Safety

Avoid Static Electricity Risk When Refueling The removal of sulfur and other compounds in Ultra-Low Sulfur Diesel (ULSD) fuel decreases its conductivity and increases its ability to store a static charge. RG22142 —UN—17MAR14

Refineries may have treated the fuel with a static dissipating additive. However, there are many factors that can reduce the effectiveness of the additive over time. Static charges can build up in ULSD fuel while it is flowing through fuel delivery systems. Static electricity discharge when combustible vapors are present could result in a fire or explosion.

RG21992 —UN—21AUG13

Therefore, it is important to ensure that the entire system used to refuel your machine (fuel supply tank, transfer pump, transfer hose, nozzle, and others) is properly grounded and bonded. Consult with your fuel or fuel system supplier to ensure that the delivery system is in compliance with fueling standards for proper grounding and bonding practices.

Coolant Control Valve Verification

CAUTION: Explosive release of fluids from pressurized cooling system can cause serious burns. Do not open coolant system until the coolant temperature is below operating temperature. Always loosen cooling system filler cap, radiator cap, or drain valve slowly to relieve pressure. IMPORTANT: Ensure that the hose is secured to the container. If the valve is stuck open, coolant flows from the outlet port. Ignition OFF, engine OFF. Disconnect coolant supply and return lines from the coolant control valve (Y5019). See Diesel Exhaust Fluid (DEF) Harness (W54) Component Location. (Group 9015-10.) Attach a line to the coolant control valve outlet port and route to a suitable container. Using a regulated air supply no greater than 103 kPa (1.03 bar) (15 psi), blow air into the coolant control valve inlet port.

YES: Replace coolant control valve (Y5019). See Diesel Exhaust Fluid (DEF) Harness (W54) Component Location. (Group 9015-10.)

Group 10

Operational Checkout Procedure Operational Checkout to doing checkout. The machine must be at operating temperature for many of the checks. See Hydraulic Oil Warm-Up Procedure. (Group 9025-25.)

This procedure is used to check operation of machine. The procedure is designed so the operator can do a walk-around inspection, check machine operation, and perform specific checks from the operator's seat. If there is a problem with machine, diagnostic information in this checkout will help pinpoint the probable cause. This information may allow the operator to perform a simple adjustment to correct the problem. Use the table of contents to help find adjustment procedures. A location will be required which is level and has adequate space to complete checks. No tools or equipment are needed to perform checkout. Complete necessary visual checks (oil levels, oil condition, external leaks, loose hardware, linkage, wiring) prior

Read each check completely before performing. If no problem is found, the operator will be instructed to go to the next check. If a problem is indicated, the operator will be referred to a procedure for adjustment, repair, or replacement. The monitor can be used to perform diagnostic and operational checks. The monitor can display engine speed, pressures, and diagnostic trouble codes (DTCs). Before performing any check or test below, verify battery disconnect is turned to the ON position. JJ03229,0001128 -19-23JAN18-1/55

Diagnostic Trouble Code Check JJ03229,0001128 -19-23JAN18-2/55

Display and Clear Trouble Always check for diagnostic trouble codes and correct them before performing Codes operational checkout. Diagnostic trouble codes can be displayed by using one of the following methods:

• Monitor • With Service ADVISOR™ • MPDr

YES: Correct all diagnostic trouble codes before proceeding. See Reading Diagnostic Trouble Codes With Service ADVISOR™ Diagnostic Application, see Reading Diagnostic Trouble Codes With Monitor Display, or see MPDr Application. (Group 9015-20.)

LOOK: Are diagnostic trouble codes present?

Cold Weather Starting Aid Glow plugs provide three possible stages of cold start aid: preheat, run-up heat, and reheat. If engine control unit (ECU) determines charge air cooler outlet temperature is below a predetermined setpoint (see table below), ECU sends current to glow plug relay, energizing the relay. With relay energized, glow plugs heat the air in the combustion chamber for the duration indicated in the following glow plugs preheat time table. The operator may start engine at any time during preheat; however, the ECU will de-energize the glow plug relay during cranking.

Run-up heat time is dependent on how long engine takes to increase speed from 10 rpm to 800—1000 rpm. The maximum run-up heat time allowed is 60 seconds. If preheat time is 0, then run-up heat is not performed. After engine has started and reached 800—1000 rpm, the ECU will determine if a reheat period is necessary using charge air cooler outlet temperature and comparing the results to glow plugs reheat time table below. If preheat time is 0, then reheat is not performed. For more information concerning cold weather starting aid, see Engine Control Unit (ECU) Circuit Theory of Operation. (Group 9015-15.)

The main controller (MCZ) uses input signals from the engine speed dial, hydraulic pressure sensors, and temperature sensors to determine appropriate engine speed. The main controller then sends a signal via controller area network (CAN) to the engine control unit (ECU). The ECU then sets engine rpm.

H/P (High Power) Mode The purpose of H/P mode is to increase engine speed using certain hydraulic functions. The main controller sends a signal to the ECU via CAN to raise engine rpm when the following conditions are met:

• Power mode: H/P. • Work mode: Bucket. • Engine speed dial set to fast idle. • Arm in, boom up, or a combination of both functions

The main controller uses input signals from the travel pressure sensor, engine speed dial, travel mode switch (3), and delivery pressure sensors to determine appropriate engine speed. The main controller then sends a signal via CAN to the ECU to increase engine speed when the following conditions are met:

• Engine speed dial set to fast idle. • Travel mode switch is at fast (rabbit) speed position. • Travel pressure sensor is on. • Either pump 1 or pump 2 delivery pressure sensor must

actuated.

• Pump delivery pressure high.

indicate high pressure.

PWR (Power) Mode

Heater Control

The function of PWR mode is to control the engine speed from slow idle to fast idle in response to the position of the engine speed dial.

NOTE: Heater control engine mode is independent of heating and air conditioning system operation. Operation of heating and air conditioning system will not change engine speeds.

ECO (Economy) Mode The purpose of ECO mode is to lower engine speed to reduce fuel consumption and noise level. The main controller receives input signals from the engine speed dial, power mode button (4), and pump delivery pressure sensors, and then sends a signal via CAN to the ECU to reduce engine rpm when the following conditions are met:

• Engine speed dial set to greater than ECO mode speed. • Power mode: ECO. Travel HP (High Power) Mode Control The purpose of travel HP mode control is to increase engine speed for faster travel.

The purpose of the heater control selection is to accelerate the warm-up speed of the cab heater by increasing the engine speed at low engine coolant temperature. The main controller sends a signal via CAN to the ECU to increase the engine rpm when the following conditions are met:

• Engine speed dial set to fast idle. • Engine coolant temperature is 5°C (41°F) or lower. • Pilot shutoff lever in the locked (UP) position. Heater control selection is activated when the key switch is turned ON and is deactivated if any other engine speed controls are activated.

Theory of Operation

Heater control selection can be activated or deactivated in the monitor or MPDr. See Machine Setting. (Group 9015-16.) Also, see Heater Control Disable and Enable. (Group 9015-20.)

until the engine coolant temperature rises above 50°C (122°F). 4. Only after the engine coolant temperature has risen above 50°C (122°F) will the warm-up circuit deactivate and engine run at user-selected idle speed.

Auto-Idle Control

Engine Coolant Temperature Management

The purpose of auto-idle control is to lower engine speed to reduce fuel consumption and noise levels while engine is running and no hydraulic functions are actuated.

NOTE: If engine coolant temperature management (ECTM) is unable to achieve desired coolant temperature after 80 minutes, exhaust temperature management (ETM) will not activate. Key cycle is required to reset ECTM and ETM.

The main controller uses input signals from hydraulic pressure sensors, engine speed dial, and power mode button to determine appropriate engine speed. The main controller then sends a signal via CAN to the ECU to lower engine rpm.

The main controller sends a signal via CAN to the ECU to adjust engine rpm according to the following conditions:

Auto-idle is activated when the following conditions are met:

• Auto-idle switch (2) in the auto-idle ON position. • No functions activated for approximately 4 seconds. • Engine speed is greater than auto-idle speed. Auto-idle control is deactivated when the following conditions are met:

• Auto-idle switch turned to OFF position. • A hydraulic function is actuated. • Power mode button is pressed from ECO to PWR, PWR to H/P, or H/P to ECO.

• Engine speed dial is turned to change engine speed. When auto-idle is deactivated, the engine rpm increases to the setting of the engine speed dial. Auto Warm-Up Control The purpose of auto warm-up control is to increase engine coolant and hydraulic oil temperatures to proper operating temperatures. Warm-up is achieved by increasing engine speed. The main controller determines the appropriate target engine speed for auto warm-up. The main controller then sends a signal via CAN to the ECU to adjust engine rpm according to the following conditions: 1. Only when hydraulic oil temperature is below 0°C (32°F) will the main controller send a signal to the ECU to run the engine between 1300—1500 rpm until the hydraulic oil temperature rises above 0°C (32°F). Engine coolant temperature is not considered for auto warm-up by the main controller when hydraulic oil temperature is below 0°C. 2. When hydraulic oil temperature is above 0°C (32°F) and engine coolant temperature is 0—25°C (32—77°F), the main controller sends a signal to the ECU to run the engine between 1350—1450 rpm until the engine coolant temperature rises above 25°C (77°F). 3. When hydraulic oil temperature is above 0°C (32°F) and engine coolant temperature is 25—50°C (77—122°F), the main controller sends a signal to the ECU to run the engine between 1150—1250 rpm

1. Only when coolant temperature is below 60°C (140°F) will the main controller send a signal to the ECU to run engine at 1200 rpm for up to 20 minutes or until engine coolant reaches 60°C (140°F). 2. Only when coolant temperature is below 60°C (140°F) will the main controller send a signal to the ECU to run engine at 1400 rpm for up to 20 minutes (after the engine has already ran for 20 minutes at 1200 rpm) or until engine coolant reaches 60°C (140°F). 3. Only when coolant temperature is below 60°C (140°F) will the main controller send a signal to the ECU to run engine at 1600 rpm for up to 40 minutes (after the engine has already ran for 20 minutes at 1200 rpm and 20 minutes at 1400 rpm or until engine coolant reaches 60°C (140°F). 4. Only after the engine coolant temperature has risen above 60°C (140°F) will the warm-up control deactivate and engine run at user-selected idle speed. Idle Speed-Up Control The purpose of the idle speed-up control is to increase the engine rpm when a function is actuated at slow idle. The main controller uses these input signals from the travel pressure sensor, front attachment pressure sensor, and engine speed dial to determine appropriate engine speed. The main controller then sends a signal via CAN to the ECU to increase the engine rpm. Idle speed-up is activated when the following conditions are met:

• Engine speed set to slow idle. • Function is actuated. ECO Control The purpose of ECO control is to reduce engine speed from fast idle in order to reduce fuel consumption and noise level. Fast idle engine speed will be reduced immediately after no functions are active. Main controller sends a signal to the ECU using CAN communication after functions are set to neutral. When any hydraulic function is actuated, engine speed will increase. ECO control, in addition to auto-idle, is a function to reduce engine speed. ECO control can be enabled and disabled through MPDr.

The System Functional Schematic is made up of equal sections to simplify searching the schematic. Each section of the System Functional Schematic is assigned a number (7). The System Functional Schematic is formatted with power supply wires (2) shown near the top of the drawing and ground wires (5) near the bottom. The schematic may contain some harness or connector information. When connector information is shown, it will be displayed as a double chevron (12) with a component identification number (11) corresponding to the connector identification number. Connector pin information (13) will be displayed in a text size smaller than that of the connector identification number. Each electrical component is shown by a schematic symbol (10), the component name (8), and a component

identification number (9). A component identification number and name will remain the same throughout the Operation and Test Technical Manual. This will allow for easy cross-referencing of all electrical drawings (Schematics, Wiring Diagrams, and Component Location). Routing location information (3) is presented to let the reader know when a wire is connected to a component in another section. TO and FROM statements identify when power is going “To” or coming “From” a component in a different location. The section and component identification number are given in the first line of information and any pin information for the component is given in parenthesis in the second line. In this example, power is going TO section 23, component B14 on pin C4.

System Diagrams Explanation of Wire Markings Electrical harness wires are identified by color, with no number stamped on wire. Wire numbers are used on some connector drawings simply as reference numbers, useful in tracing wires through the harness. Some wires are solid wire colors. These would be identified by one color name such as RED or BLK or GRN. Other wire colors are identified with two color names. These are solid wires with a narrow stripe. For example, a wire identified as RED/WHT would be a primarily RED wire, with a WHT stripe. A wire identified as WHT/RED would be a primarily WHT wire with a RED stripe. Following is a listing of wire color abbreviations used on drawings.

• BLK—Black

• BLU—Blue • BRN—Brown • CABLE—Bare Wire • DK GRN—Dark Green • GRN—Green • GRY—Grey • LT BLU—Light Blue • LT GRN—Light Green • ORG—Orange • PNK—Pink • PUR—Purple • RED—Red • SK BLU—Sky Blue • TAN—Tan • VLT—Violet • WHT—White • YEL—Yellow DS35042,0000038 -19-15MAR11-1/1

Controller Area Network (CAN) Overview—The controller area network (CAN) provides a standardized means for electronic controllers and other devices to communicate with each other.

• Engine Control Unit (ECU) (A1) • Main Controller (MCZ) (A3) • Monitor Controller (DSZ) (A4) • Flex Power Controller (FPC) (A15) • Modular Telematics Gateway (MTG) Controller (A6000)

The CAN consists of two buses (wires): CAN high and CAN low. These two wires carry signals opposite of each other to overcome noise interference and minimize communication errors. The high and low wires, and sometimes a ground wire, are woven together, which provides an additional method of reducing interference and thus helps the devices communicate with minimal errors. When woven together with a ground wire, the three wires are commonly referred to as a twisted triple.

Operations and functions of the individual devices on CAN 0 are covered separately.

• For the ECU, see Engine Control Unit (ECU) Circuit Theory of Operation. (Group 9015-15.)

• For the MCZ, see Main Controller (MCZ) Circuit Theory of Operation. (Group 9015-15.)

• For the DSZ, see Monitor Controller (DSZ) Circuit

The 120-ohm termination resistors, usually located at opposite ends of the CAN bus, also help prevent signal errors. With the key switch in the OFF position, the resistance between the CAN high and CAN low circuits would measure 55—65 ohms. Resistance drops in half because there are two paths for electrical current to flow in a parallel circuit. Total circuit resistance will always be less than any resistors in the circuit. Total circuit resistance can be calculated by using the following equation: R1 x R2 / (R1 + R2) = Total Resistance The CAN is an arbitration-based system. This means a low-priority message always allows a high-priority message to go first. Each CAN device checks to see if the bus is idle before it transmits a signal. Whichever device gets on the bus first is able to transmit its signal. When collision occurs, that is, when two or more devices are transmitting at the same time, the device with the lowest ID has higher priority to access the bus. The device that loses arbitration immediately retransmits its signal when the device with the higher priority has completed its transmission. This machine contains five CAN circuits: CAN 0, CAN 1, interface CAN, engine CAN, and aftertreatment CAN. CAN 0—The CAN 0 circuit provides the communication link for the following devices:

CAN 0 also includes the following components:

• CAN 0 Termination Resistor (R5601) • Service ADVISOR™ Diagnostic Connector (X1) CAN 0 utilizes two terminating resistors: CAN 0 termination resistor (R5601) and another located inside monitor controller (DSZ) (A4), which is not accessible. The Service ADVISOR™ diagnostic connector provides an interface for connecting diagnostic equipment such as a laptop. See Service ADVISOR™ Diagnostic Application. (Group 9015-20.) CAN 1—The CAN 1 circuit provides the communication link for the following devices:

• Main Controller (MCZ) (A3) • Monitor Controller (DSZ) (A4) • Data Converter (A5) • Radio (A6) • Air Conditioner Controller (ACF) (A7) • Machine Controller (BCZ) (A11) Operations and functions of the individual devices on CAN 1 are covered separately.

• For the MCZ, see Main Controller (MCZ) Circuit Theory of Operation. (Group 9015-15.)

Unswitched power is supplied to the following components:

• Battery Relay (K19) • Key Switch (S1) (from battery 45 A fuse [F61]) • Main Controller (MCZ) (A3) (from data converter

and main controller battery power 5 A fuse [marked CONTROLLER] [F10]) • Machine Controller (BCZ) (A11) (from data converter and main controller battery power 5 A fuse [marked CONTROLLER] [F10]) • Data Converter (A5) (from data converter and main controller battery power 5 A fuse [marked CONTROLLER] [F10]) • Engine Control Unit (ECU) (A1) - From Engine Control Unit (ECU) 20 A Fuse (marked ECU P1) (F8) - From Engine Control Unit (ECU) 20 A Fuse (marked ECU P2) (F36) - From Engine Control Unit (ECU) 20 A Fuse (marked ECU P3) (F37) • Monitor Controller (DSZ) (A4) (from radio backup 10 A fuse [marked BACK UP] [F9]) • Load Dump Relay (K1)

relay (K12). Utilizing the normally closed contacts of accessory cut relay, power is supplied through accessory cut diode (V11) and monitor 5 A fuse (F14) to pin B17 of the monitor controller (DSZ) (A4), powering the DSZ. Key switch pin M also receives power, supplying idle stop relay (K11), accessory cut relay (K12), and key cut relay (K13) through idle stop 5 A fuse (F18). Utilizing the normally closed contacts of key cut relay, power is passed through pin 3 of key cut relay, next through load dump relay diode (V3), then to pin S of battery relay (K19), energizing the battery relay. Ground is provided to pin E of battery relay. When energized, the battery relay allows current to pass through to pin B of starter motor (M1) and pin 3 of starter relay (K34). Power is also passed through to alternator 65 A fuse (F60), providing a path from pin B of alternator (G3) to the batteries (G1 and G2). Utilizing the normally closed contacts of the key cut relay, current is passed to pin A16 of monitor controller (A4), indicating the key switch is in the ON/START position. Engine Start

Battery Disconnect Switch The battery disconnect switch (S91) is used to isolate electrical power from batteries (G1 and G2) to ground. The battery disconnect switch has two positions: OFF and ON. Once the machine has been shut down with key switch, the battery disconnect indicator light (E22) stays illuminated until turning the battery disconnect switch to the OFF position is safe. For more information about the battery disconnect switch, see Battery Disconnect Switch. (Operator’s Manual.) For more information about the battery disconnect indicator light, see Engine Control Unit (ECU) Circuit Theory of Operation and see Exhaust Aftertreatment Circuit Theory of Operation. (Group 9015-15.) Ignition ON When key switch (S1) is placed in the ON position, current flows from key switch pin ACC to pin 3 of accessory cut

When key switch (S1) is moved to the START position, current flows from key switch pin ST to pins 1 and 3 of starter cut relay (K4) and through start position signal 5 A fuse (F7) to pin A17 of monitor controller (A4), indicating the key switch is in the START position. Utilizing the normally closed contacts of starter cut relay, power is supplied to pin 1 of starter relay (K34). With battery relay (K19) energized from the ignition ON position, power from battery relay pin A is supplied to pin B of starter motor (M1) and pin 3 of starter relay (K34) through starter in-line 30 A fuse (F45). Starter relay (K34) is a normally open relay, which closes when power is present on pin 1 and ground is present on pin 2. Energized starter relay provides power from battery relay (K19) to pin S of starter motor (M1). When power is present on starter motor pins B and S, the starter rotates thus cranking the engine. When the starter relay is de-energized, starter relay contacts are opened, removing power from starter pin S, stopping the starter motor from turning.

Sub-System Diagnostics

Starter cut relay (K4) utilizes the normally closed contacts of the relay to continue the start signal to pin 1 of starter relay (K34). Starter cut relay is energized when there is power from the key switch present at pin 1 and ground on pin 2, preventing the starter motor from cranking the engine. The ground on pin 2 is supplied from the monitor controller (DSZ) (A4), pilot shutoff switches (S3 and S4), main controller (MCZ) (A3), or the engine control unit (ECU) (A1). A ground from the monitor controller is the result of a security code violation or machine warning alarm. A ground from pilot shutoff switches or the main controller is the result of the pilot shutoff lever in the unlocked (DOWN) position or an error in the pilot shutoff circuit. A ground from the engine control unit is based on the engine run status, which prevents the starter from engaging while the engine is running.

engine control unit (ECU) connector 1 (X5501) to pin 1 of the glow plug relay (K16), current is supplied from pin 32 of ECU connector 1 to pin 2 of the glow plug relay, energizing the relay. Current from pin 3 on glow plug relay is sent to pin 54 of ECU via engine control unit (ECU) connector 1 (X5501) for diagnostics and to glow plugs (R1—R4). With the relay energized, the glow plugs heat the air in the combustion chamber for a set duration. When the ECU determines that coolant temperature is at operating temperature, the ECU stops current to the glow plug relay and glow plugs. The operator may start the engine at any time during the preheat; however, the ECU will de-energize the glow plug relay during cranking. For more information on the glow plugs (cold start) circuit, see Cold Weather Starting Aid. (Group 9010-05.)

When a warning alarm or security code error is detected, pin D16 of monitor controller is connected to ground. When a malfunction in the pilot shutoff circuit is detected, pin B10 of monitor controller is connected to ground. With either pin D16 or pin B10 of the monitor controller connected to ground the starter cut relay (K4) is energized through security diode (V4), removing the start signal from starter relay (K34). With no start signal at starter relay, the relay remains de-energized, removing power from pin S of starter motor (M1), preventing engine from starting. When pilot shutoff switches 1 and 2 (S3 and S4) are closed and pilot shutoff lever is in the unlocked (DOWN) position, pin 2 of starter cut relay is connected to ground through starter cut relay diode (V5), removing the start signal from the starter relay. With no start signal at starter relay, the relay remains de-energized, removing power from pin S of starter motor. Removing power from pin S prevents the activation of starter motor when pilot shutoff lever is in the unlocked (DOWN) position. For more information on the pilot shutoff circuit, see Pilot Shutoff Circuit Theory of Operation. (Group 9015-15.)

Alternator (G3) provides power to all machine circuits and charges the batteries when the engine is running.

When the engine is running, the engine control unit (ECU) (A1) will ground to pin 2 of starter cut relay (K4), opening the normally closed contacts of the starter cut relay, removing the start signal from starter relay (K34) and preventing the starter from engaging while the engine is running. When the engine is not running, the engine control unit will not ground starter cut relay. Security diode (V4), starter cut relay diode (V5), pilot shutoff diode (V9), starter protection diode (V10), accessory cut diode (V11), starter cut diode (V12), and pilot shutoff switch diode (V20) work as logic gates to allow more than one device to control one circuit without backfeeding other circuits.

Charging Circuit

Pin B1+ of the alternator is connected to battery positive (+) through alternator 65 A fuse (F60) when the battery relay (K19) is energized. When key switch (S1) is in the ON position and engine is running, current flows from pin 34 of engine control unit (ECU) connector 2 (X5502) to pin D+ of the alternator. Current from pin D+ of the alternator flows through the alternator field windings, causing excitation of the windings. Current then flows from pin B1+ of the alternator through pins A and B of battery relay (K19) to battery positive (+) terminal, charging the batteries (G1 and G2). The ECU monitors battery and alternator system voltage. When low voltage is detected, the ECU sends message over the controller area network (CAN) to the monitor controller (DSZ) (A4), the DSZ then activates the alternator alarm indicator on the monitor. For more information on CAN communication, see Controller Area Network (CAN) Theory of Operation. (Group 9015-15.) Auto-Shutdown Control The auto-shutdown feature allows the main controller (MCZ) to automatically turn off ignition power and stop the engine in order to reduce fuel consumption if no operation is active for set amount of time. The main controller (MCZ) sends the auto-shutdown signal to the monitor controller (DSZ) via the controller area network (CAN) when the following conditions have been met:

Glow Plugs (Cold Start) Circuit The engine control unit (ECU) determines when glow plugs are needed. The ECU provides ground to pin 21 of

• Pilot shutoff lever is in the locked (UP) position • Auto-shutdown enabled • Engine coolant temperature is greater than 60°C (140°F) and less than 100°C (212°F)

• Manual exhaust filter cleaning not active

Sub-System Diagnostics

When auto-shutdown timer expires, the main controller (MCZ) reduces demand engine speed to slow idle, and provides ground to the idle stop relay (K11) via pin C5. With idle stop relay energized, accessory cut relay (K12) and key cut relay (K13) are energized via ground at idle stop relay pin 5 and MCZ pin C5. With accessory cut and key cut relays energized, power is removed from ignition ON and accessory (ACC) circuits. With no power on the ignition circuit, the controllers are powered down, including the engine control unit (ECU), stopping the engine. The time duration is selectable by accessing the SETTINGS MENU >> AUTO SHUTDOWN menu in the monitor service menu. See Main Menu—Setting Menu—Auto-Shutdown. (Operator’s Manual.) Load Dump Circuit The load dump circuit consists of load dump relay (K1) and load dump relay diode (V3).

When the alternator (G3) is generating electricity, voltage is detected by the engine control unit (ECU) and the ECU sends a message over the controller area network (CAN) to the monitor controller (DSZ) (A4), causing the monitor controller to put pin D8 of monitor controller to ground and energizing load dump relay (K1). With load dump relay (K1) energized, battery power is applied through pins 3 and 5 to battery relay (K19). Monitor controller (DSZ) (A4) pin D8 retains a ground path for load dump relay (K1) until alternator (G3) stops producing output voltage, keeping the battery relay (K19) energized and providing a path to the batteries (G1 and G2) for any power produced by the alternator (G3) as the engine slows to a stop. Therefore, the ground path is removed from load dump relay, and battery relay (K19) is de-energized. For more information, see Controller Area Network (CAN) Theory of Operation. (Group 9015-15.)

NOTE: The information controller (ICZ) is an internal controller of the monitor controller (DSZ). Monitor Controller (DSZ) (A4)—The monitor controller (DSZ) contains the monitor software and interprets inputs from various sensors, buttons, and switches. Information sent over the controller area network (CAN) from other controllers is sent to the DSZ where information is then displayed on the monitor. The DSZ uses the CAN 1 to communicate with the data converter (A5), radio (A6), air conditioner controller (ACF) (A7), machine controller (BCZ) (A11), and main controller (MCZ) (A3) through pins A25 and A26 of DSZ. The DSZ also communicates on CAN 0 with the engine control unit (ECU) (A1), flex power controller (FPC) (A15), and the main controller (MCZ) (A3) through pins A23 and A24 of DSZ. For more information on CAN communication, see Controller Area Network (CAN) Theory of Operation. (Group 9015-15.) Monitor Controller (DSZ) (power and ground)—Unswitched battery power is available through battery 45 A fuse (F61) and radio backup 10 A fuse (F9) to pin B18 of the monitor controller (DSZ). Battery power from battery 45 A fuse is also provided to pins 1 and 3 of load dump relay (K1). Ground is provided to pins A22, B11, B35, and B36 of the DSZ. When key switch (S1) is in the accessory (ACC) position, current flows from pin ACC of key switch to accessory cut relay (K12). Utilizing the normally closed contacts of accessory cut relay, current flows through accessory cut diode (V11) and through monitor 5 A fuse (F14) to pin B17 of the DSZ. Accessory power enables the radio and air conditioning and heating electronic features to operate without powering up the other vehicle controllers. When the key switch is in the ignition ON position, current flows to pin M in addition to pin ACC. Current from pin M flows to key cut relay (K13) directly to pin 3 and through idle stop 5 A fuse (F18) to pin 1 of key cut relay, pin 1 of idle stop relay, and pin 1 of accessory cut relay. Utilizing

the normally closed contacts of the key cut relay, current flows through load dump relay diode (V3) to pin 5 of load dump relay and to battery relay (K19), energizing the battery relay. Current from key cut relay also flows through power on 5 A fuse (F17) to pin A16 of the DSZ, powering up the DSZ. When the key switch is in the START position, current flows to pin ST in addition to pin M. Current from key switch pin ST flows to pins 1 and 3 of starter cut relay (K4), and through start position signal 5 A fuse (F7) to pin A17 of the DSZ, indicating the key switch is in the START position. Anti-Theft Security—The anti-theft security circuit consists of security alarm relay (K3) and security alarm (H2). Battery power is provided to pin 1 of security alarm relay and to pin 1 of the security alarm through radio backup 10 A fuse (F9). When an invalid code has been entered, ground is provided to pin 2 of security alarm relay from pin D15 of the monitor controller (DSZ), energizing the security alarm relay and activating the security alarm. When the anti-theft security circuit is active, ground is provided to starter cut relay (K4), disabling the starter motor (M1) and preventing the machine from starting. For more information, see Starting and Charging Circuit Theory of Operation. (Group 9015-15.) Monitor Warning Alarm—The monitor warning alarm (H3) sounds when certain diagnostic trouble codes (DTCs) or machine conditions exist, which could damage the machine. The monitor warning alarm receives switched power from power on 5 A fuse (F17). Ground is provided from pin D7 of monitor controller (DSZ), activating the alarm. Alternator Voltage Indicator—The alternator voltage is monitored by the engine control unit (ECU) (A1). When the alternator voltage is below charging level or the battery voltage is low, the ECU sends a message over the controller area network (CAN) to the monitor controller (DSZ) (A4), the DSZ then illuminates the alternator alarm indicator on the monitor. The monitor controller also uses this signal from the ECU to activate the load dump circuit.

Engine Control Unit (ECU) (A1)—The engine control unit (ECU) uses information received from various sensors to determine the correct amount of fuel and injection timing based on load, temperatures, and operator input. Some of the data calculated by the ECU is transmitted across the controller area network (CAN) to the main controller (MCZ) (A3), monitor controller (DSZ) (A4), flex power controller (FPC) (A15), and modular telematics gateway (MTG) controller (A6000). The DSZ forwards much of the information across the CAN data line to the monitor where the information is displayed on the appropriate screen. NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.)

• For information concerning the MCZ, see Main

Controller (MCZ) Circuit Theory of Operation. (Group 9015-15.) • For information concerning the DSZ, see Monitor Controller (DSZ) Circuit Theory of Operation. (Group 9015-15.)

• Engine Mode The ECU contains a barometric air pressure (BAP) sensor that is located inside the ECU. This sensor is used to determine the pressure of the ambient air at the mounting location of the ECU. The BAP sensor helps the ECU determine the air density for calculating the correct air-fuel ratio. This sensor cannot be repaired or replaced without replacing the entire ECU. The ECU also contains a temperature sensor that is located inside the ECU. This sensor is used to determine the internal temperature of the ECU. If the ECU temperature exceeds specification, the ECU limits the speed of the engine in an attempt to protect the ECU from permanent damage. Temperature sensor cannot be repaired or replaced without replacing the entire ECU.

• Programming—The ECU can be programmed by

Whenever an engine DTC occurs, the information is captured or recorded. The information generated is called a Snapshot. The Snapshot information is categorized into two types: Snapshot Capture and Snapshot Recording. For more information, see Snapshot Instructions. (CTM120119.)

downloading the latest programs from the software delivery system (SDS). • Compression Test—This test is used to determine the relative compression of each cylinder. The engine is cranked while being provided with no fuel. The angular period of the crankshaft is measured near top dead center (TDC), and again past TDC. The periods can be converted to velocities, and the relative decelerations can be calculated from the difference in the velocities. The deceleration is a function of the pressure in the cylinder. By comparing the result from each cylinder, cylinders with relatively low compression can be identified. • Cylinder Cutout-Misfire Test—This test provides the capability to cutout fuel to individual cylinders and provide a programmable fuel command to the other cylinders for a programmable number of cylinder firing events. The total time for the number of firing events is determined and made available to Service ADVISOR™ for analysis. ECU Power Up (power and ground)—Unswitched battery power is available from:

• Fuse F37—Pins 13 and 14 of engine control unit (ECU) connector 3 (X5503).

Ground is provided at pin 22 via engine control unit (ECU) connector 2 (X5502) and pins 16, 17, 27, 43, and 44 via engine control unit (ECU) connector 3 (X5503). When key switch (S1) is in the ON position, current flows from pin M of key switch to pin 3 of key cut relay (K13) and through idle stop 5 A fuse (F18) to pin 1 of key cut relay. Utilizing the normally closed contacts of the key cut relay, current is passed to pin 7 of engine control unit (ECU) connector 3 (X5503) through power on 5 A fuse (F17), causing the ECU to power up. When key switch (S1) is in the START position, current flows from pin ST through the normally closed contacts of starter cut relay (K4) to starter relay (K34), energizing the relay. With the starter relay energized, power is supplied to pin S of starter motor (M1), thus cranking the engine. Once the ECU has determined the engine has started, pin 05 of engine control unit (ECU) connector 3 (X5503) is grounded, providing ground to starter cut relay, energizing the relay. With starter cut relay energized, the start signal is removed from the starter relay, de-energizing the starter relay, thus disengaging the starter motor. When the engine is running the ECU provides excitation from pin 34 of engine control unit (ECU) connector 2 (X5502) to pin D+ of the alternator (G3) for the charging circuit. For more information, see Starting and Charging Circuit Theory of Operation. (Group 9015-15.)

torque message is sent. Before applying a new torque command, the ECU verifies the watchdog indicator has changed from the previous message. If the ECU detects that the torque command message is not being updated at the expected rate or if two consecutive messages have the same watchdog indicator value, the ECU will default to the lowest torque curve and set the appropriate diagnostic trouble code (DTC). The FPC is used to monitor the system voltage. The FPC uses engine speed and system voltage data, received via CAN from the ECU, to determine the state of the alternator and battery. If the voltage is below a predefined threshold with the engine running, a DTC is created and a message is sent via CAN to the monitor controller (DSZ) (A4) to activate the alternator light on the monitor. The FPC interfaces with the modular telematics gateway (MTG) controller (A6000) and the monitor controller (DSZ) (A4) to communicate the availability of software updates for the machine controllers via Service ADVISOR™ Remote (SAR). The Service ADVISOR™ Remote (SAR) switch (S18) is used to accept or decline these updates. The FPC monitors the status of parked exhaust filter cleaning cycles. The FPC will generate a DTC to warn the operator of aborted cleaning cycles. The FPC stores the machine model information in nonvolatile memory. On each power cycle, the FPC compares the model received from the main controller (MCZ) (A3) to its own stored model data. If the two do not agree, the machine model can’t be verified and the flex power function will default to the low torque curve. Flex Power Controller (FPC) (Power and Ground)—Unswitched battery power is available at pins L1 and L2 of flex power controller (FPC) (A15) through fuel transfer pump and controllers 20 A fuse (marked ECU P4) (F38) and through flex power controller (FPC) in-line 10 A Fuse (F5004). Ground is provided at pin M2 and pin M3 of FPC.

Flex Power Controller (FPC) (A15)—The FPC provides several functions: flex power control, system voltage monitoring, Service ADVISOR™ Remote (SAR), and exhaust filter cleaning malfunction notice. FPC is used to allow the vehicle system to adjust the maximum available torque between two predefined torque curves. The flex power function allows the engine torque level to be defined via CAN by the FPC. However, the engine control unit (ECU) and FPC both contain a common data table defining the minimum and maximum torque at each speed within the operating range of the engine. The ECU updates the FPC with the current engine speed every 20 milliseconds. Once the FPC receives the engine speed, it then computes the new torque command for that speed as a percentage between the minimum and maximum torque values in the data table. Every 20 milliseconds, the FPC sends an updated torque command to the ECU which also includes a watchdog indicator, which is simply a counter that increments each time the

When key switch (S1) is in the ON position, current flows from pin M of key switch to pin 3 of key cut relay (K13) and through idle stop 5 A fuse (F18) to pin 1 of key cut relay. Utilizing the normally closed contacts of the key cut relay, current flows through power on 5 A fuse (F17) to pin M1 of FPC, causing the FPC to power up. NOTE: For power up of the other electronic controllers, see the theory of operation of specific component:

Service ADVISOR™ Remote (SAR) Switch (S18)—The Service ADVISOR™ Remote (SAR) switch (S18) allows the operator to accept or decline available updates. The flex power controller (FPC) (A15) will create DTCs under certain trigger conditions, which will send a message via CAN to the monitor controller (DSZ) (A4) to prompt the vehicle to display operator instructions on the monitor. When key switch (S1) is in the ON position, current flows from pin M of key switch to pin 3 of key cut relay (K13) and through idle stop 5 A fuse (F18) to pin 1 of key cut relay. Utilizing the normally closed contacts of the key cut relay, current is passed through power on 5 A fuse (F17) to pins 1, 7, and 10 of Service ADVISOR™ Remote (SAR) switch (S18). When the SAR switch is pressed to the ACCEPT position, current is sent through pin 3 of the SAR switch to pin C1 of FPC. Pin E3 of FPC, is then grounded, completing the circuit to pin 5 of the SAR switch, activating the ACCEPT (green) light emitting diode (LED). When the SAR switch is pressed to the DECLINE position, current is sent through pin 2 of the SAR switch to pin F2 of FPC. Pin F3 of FPC, is then grounded, completing the circuit to pin 4 of the SAR switch, activating the DECLINE (red) light emitting diode (LED). Cold Weather Starting Aid—Power is available to pin 3 of glow plug relay (K16) from glow plug 50 A fuse (F63). Ground is provided at pin 1 of glow plug relay and to glow plugs (R1—R4). When key switch (S1) is in the ON position, current flows from pin M of key switch to pin 3 of key cut relay (K13) and through idle stop 5 A fuse (F18) to pin 1 of key cut relay. Utilizing the normally closed contacts of the key cut relay, current is passed to pin 7 of engine control unit (ECU) connector 3 (X5503) through power on 5 A fuse (F17), causing the ECU to power up. The ECU now determines if the glow plugs need to be activated. If the ECU determines the glow plugs are necessary, power is

sent out pin 32 via engine control unit (ECU) connector 1 (X5501) to pin 2 of glow plug relay, energizing the relay. Power is sent to glow plugs and through glow plug resistor (R19) to engine control unit (ECU) connector 1 (X5501) pin 54. For more information on cold start aid, see Cold Weather Starting Aid. (Group 9010-05.) Hydraulic Variable Speed Fan—The variable speed fan cools the machine's systems by a hydraulic pump and motor controlled by a variable speed fan solenoid, providing machine efficiency and reducing fan noise levels by only operating the fan at the minimum speed necessary to cool the machine systems. The engine control unit (ECU) uses the following inputs to determine the proper fan speed:

• B22—Ambient air temperature sensor if air conditioner is ON via CAN.

• B40—Hydraulic oil temperature sensor via controller area network (CAN).

• B5205—Charge air cooler outlet temperature sensor at

pin 29 of engine control unit (ECU) connector 2 (X5502).

• B5208—Engine coolant temperature sensor at pin 16 of engine control unit (ECU) connector 1 (X5501).

• B5209—Fuel temperature sensor at pin 48 of engine control unit (ECU) connector 1 (X5501).

The input that requires the most cooling takes precedence over the other inputs and the fan is run at a speed sufficient to cool the warmest input. If any of the three temperature sensor inputs are invalid, the fan will run at maximum speed to ensure proper cooling. The maximum fan speed is limited to engine speed. Temperature thresholds and variable speed fan solenoid duty cycles (fan speeds) are preprogrammed into the ECU and cannot be changed. The variable speed fan solenoid (Y5014) is driven from engine control unit (ECU) pin 32 of engine control unit (ECU) connector 2 (X5502).

To protect the fan pump while operating in cold conditions, the ECU limits the fan speed according to the input from the hydraulic oil temperature sensor (B40). The ECU will increase the fan speed as hydraulic oil warms.

*When the air conditioner is ON and the ambient air temperature is over 15°C (60°F) the engine fan will increase to 1250 rpm. **The engine control unit measures the intake air temperature and adds a constant value to it at ambient temperatures above 25°C (77°F). In this application, the constant value is 27°C (80°F) above ambient air temperature when ambient air temperature is above 25°C (77°F). At temperatures below 25°C (77°F), the engine control unit uses the constant of 52°C (126°F) for the fan speed calculations. For example:

• at 20°C (68°F) ambient temperature, the ECU calculated temperature would be 52°C (126°F). • at 26°C (79°F) ambient temperature, the ECU calculated temperature would be 53°C (128°F). • at 30°C (86°F) ambient temperature, the ECU calculated temperature would be 57°C (135°F).

Hydraulic Variable Speed Fan Reversing Function (if equipped)—The hydraulic variable speed fan with reversing function controls the cooling capacity of the cooling package by varying the speed of the fan. The engine control unit (ECU) automatically controls the speed of the fan by monitoring the following:

• Engine Coolant Temperature • Hydraulic Oil Temperature • Fuel Temperature • Charge Air Cooler Outlet Temperature • Ambient Air Temperature • Air Conditioning State (On-Off)

communicates with the DSZ and ACF to set the A/C compressor value to OFF. The A/C compressor will be temporarily turned off until approximately 1 minute after the completion of a fan reversing cycle; at that time, the ECU will send communication to set the A/C compressor value to ON. For more information on the DSZ, see Monitor Controller (DSZ) Circuit Theory of Operation. (Group 9015-15.) NOTE: If a malfunction exists for any of the previously mentioned temperature sensors, the fan speed will go to full speed.

The engine coolant temperature sensor (B5208), fuel temperature sensor, and charge air cooler outlet temperature sensor (B5205) are hard wired to the engine control unit (ECU). The hydraulic oil temperature is hard wired to the main controller (MCZ) (A3) and continuously transmits information across the controller area network (CAN) to communicate with the ECU. For more information on the hydraulic oil temperature sensor, see Main Controller (MCZ) Circuit Theory of Operation. (Group 9015-15.) The air conditioner compressor clutch is hard wired to the air conditioner controller (ACF) and continuously transmits information via CAN to communicate with the monitor controller (DSZ), which then forwards the information via CAN to the ECU. During a reversing cycle, the ECU

The engine control unit (ECU) uses certain reference values in the form of look-up tables for each of the temperatures and the air conditioning state to determine the fan speed for each input. The ECU then selects the highest fan speed required and sends current out pin 32 of engine control unit (ECU) connector 2 (X5502) to variable speed fan solenoid (Y5014). Static ground is provided to variable speed fan solenoid at all times on pin 21 of engine control unit (ECU) connector 1 (X5501). The amount of current the ECU provides the variable speed fan solenoid is inversely dependent on the calculated fan speed and compared to a predefined look-up table. Zero current commands maximum fan speed. For hydraulic operation of the fan, see Fan Drive Hydraulic System Operation. (Group 9025-05.)

Sub-System Diagnostics

The reversing fan function reverses the fan direction to purge the cooling system of debris. The reversing fan function can be operated in manual or automatic mode via the reversing fan switch (S15). Unswitched power is provided from optional connector and reversing fan 20 A fuse (F6) to pin 3 of reversing fan switch (S15). The reversing fan function can be operated when the ECU determines that the following conditions are met:

• Engine speed is at least 1180 rpm. • Hydraulic oil temperature is greater than 12°C (54°F). • The high temperature lamp is off. See Exhaust Aftertreatment Circuit Theory of Operation. (Group 9015-15.) • Fan solenoid codes are not present in the monitor. • A reverse sequence is not in progress. NOTE: The reversing fan is inhibited for 7 seconds following a fan reversal cycle and only an ECU reset can interrupt a fan reverse cycle. The first automatic reverse cycle will begin 1 hour after key ON or an ECU reset. When the automatic reversing fan timer in the ECU reaches the preset interval or if manual mode is selected, the ECU begins the reversing sequence as follows: 1. The ECU increases the current to variable speed fan solenoid (Y5014) to slow the fan to minimum fan speed (approximately 350 rpm). 2. When fan speed is at minimum, the ECU sends current out pin 26 of engine control unit (ECU) connector 2 (X5502) to the reversing fan solenoid (Y5015), energizing the solenoid. The fan solenoid reverses the fan direction. 3. With the fan now operating in the reverse direction, the ECU decreases the current applied to the variable speed fan solenoid (Y5014) until maximum fan speed (approximately 1500 rpm) is reached. 4. The ECU operates the fan at maximum speed in reverse direction for approximately 15 seconds, then increases the variable speed fan solenoid current until the fan is at minimum speed. 5. When the fan slows to minimum speed, the ECU stops sending current to the reversing fan solenoid (Y5015), causing the fan to change back to forward direction. 6. With the fan operating in the forward direction, the ECU decreases the variable speed fan solenoid current until the normal operating fan speed is obtained. When an automatic reversing sequence is complete the ECU will start the automatic reversing fan timer according to the preset interval of 60 minutes. The reversing sequence cannot be activated again for approximately 1 minute. If the reversing fan is in the automatic mode when the manual mode is activated, the reversing fan timer is stopped and then started again after the reversing fan sequence is completed. When a manual reverse cycle is complete, the function returns to the automatic mode.

(MCZ) and sensors located on the engine. The ECU is supplied with unswitched power on engine control unit (ECU) connector 3 (X5503) pins 12 and 50 through engine control unit (ECU) 20 A fuse (marked ECU P1) (F8), pins 23 and 24 through engine control unit (ECU) 20 A fuse (marked ECU P2), and pins 13 and 14 through engine control unit (ECU) 20 A fuse (marked ECU P3). Ground is provided on engine control unit (ECU) connector 2 (X5502) pin 22 and engine control unit (ECU) connector 3 (X5503) pins 16, 17, 27, 43, and 44. The ECU is turned on by a power on 5 A fuse (F17) through pin 07 of engine control unit (ECU) connector 3 (X5503). The ECU communicates with the MCZ through a CAN (controller area network). CAN connects to ECU through pins 01, 02, and 21 of engine control unit (ECU) connector 3 (X5503). If there is a malfunction with the ECU or one of the sensor circuits it is connected to, the ECU will illuminate an indicator on the monitor controller (A4) to notify the operator of the problem. See Reading Diagnostic Trouble Codes With Monitor Display. (Group 9015-20.) See Reading Diagnostic Trouble Codes with Service ADVISOR™ Diagnostic Application. (Group 9015-20.) Engine Speed Control— The engine speed dial allows for manual adjustment of the engine speed through the main controller (MCZ) (A3) to the engine control unit (ECU) (A1). A variable voltage of 0—5 volts is sent from the engine speed dial to the MCZ. The MCZ uses this information along with the status of the power mode button, work mode switch, auto-idle switch, and information from the pressure sensors to create an engine speed output signal. The engine speed output signal from the MCZ is used by the ECU to set the engine speed. Power is supplied to pin 4 of cab harness-to-switch panel connector 3 (X29) to MCZ connector (X36) pin F25. Signal is sent from pin 5 of cab harness-to-switch panel connector 3 (X29) to MCZ connector (X34) pin D16. Ground is supplied on pin 6 of cab harness-to-switch panel connector 3 (X29) to pin F16 of MCZ connector X36. For information on auto-idle and power modes ECO, PWR, and H/P, see Engine Speed Control System Operation. (Group 9010-05.) Engine Warm-Up— When the coolant temperature is below 0°C (32°F), the engine control unit (ECU) (A1) will run the engine at 1200 rpm for 12 minutes to warm up the engine. After the 12 minute warm-up period, the engine will return to slow idle unless the main controller (MCZ) is requesting the warm-up routine for the hydraulic oil. When the hydraulic oil temperature is below 0°C (32°F), the MCZ sends a signal to ECU to increase engine speed to 1400 rpm for 15 minutes. For more information on auto warm-up control, see Engine Speed Control System Operation. (Group 9010-05.) Power Limiting— The engine control unit (ECU) (A1) has a built-in engine protection program. The ECU will derate the amount of fuel that is delivered to the engine when sensor inputs exceed normal operating ranges. For a list of these fault codes and derate percentages, see Engine Control Unit (ECU) Diagnostic Trouble Codes. (Group 9001-20.)

Exhaust Filter Parked Cleaning Switch (S16)—The exhaust filter parked cleaning switch (S16) allows the operator to perform a parked exhaust filter cleaning. With key switch (S1) in the ON position, current flows from pin M of key switch to pin 3 of key cut relay (K13) and through idle stop 5 A fuse (F18) to pin 1 of key cut relay. Utilizing the normally closed contacts of the key cut relay, current is passed through power on 5 A fuse (F17) to pin 1 of exhaust filter parked cleaning switch (S16). When the ECU has determined a parked exhaust filter cleaning is required, ground is provided to pin 5 of exhaust filter parked cleaning switch from pin 35 of engine control unit (ECU) connector 3 (X5503), completing the circuit and activating the light emitting diode (LED). When the exhaust filter parked cleaning switch is held for 3 seconds, pin 38 of engine control unit (ECU) connector 3 (X5503) is connected to ground, initiating the parked exhaust filter cleaning if all requirements are met. NOTE: For component location, see Exhaust Filter Parked Cleaning Switch Harness (W9) Component Location. (Group 9015-10.)

Battery Disconnect Indicator Light (E22)—The battery disconnect indicator light (E22) illuminates when the key switch is in the ON position and stays illuminated until it is safe to turn the battery disconnect switch (S91) to the OFF position. When the key switch is in the ON position the engine control unit (ECU) sends power from pin 30 of engine control unit (ECU) connector 3 (X5503) to the battery disconnect indicator light. When the key switch is turned to the OFF position, the ECU determines when the diesel exhaust fluid (DEF) system has purged the DEF fluid in the DEF lines. NOTE: For component location, see Engine Interface Harness (W5) Component Location. (Group 9015-10.) For more information on the DEF system, see Exhaust Aftertreatment Circuit Theory of Operation.

Fuel Rail Pressure Sensor (B5113)—The fuel rail pressure sensor (B5113) sends a pressure equivalent signal to the engine control unit (ECU). The ECU monitors fuel pressure to control the amount and timing of fuel being transferred from the high-pressure fuel pump to the high-pressure common rail (HPCR). The ECU uses this signal input to determine if fuel rail pressure is adequate for the current operating condition. The ECU will command more or less fuel from the high-pressure fuel pump by altering the signal to the high-pressure fuel pump pressure control valve (PCV) 1 (Y5022) and high-pressure fuel pump pressure control valve (PCV) 2 (Y5023). The ECU also uses this sensor to determine if there is an electronic injector problem by measuring the drop of pressure in the HPCR during each injection. The fuel rail pressure sensor is used for engine protection. The fuel rail pressure sensor uses pin 37 for supply voltage, pin 09 for ground, and pin 51 for signal on engine control unit (ECU) connector 1 (X5501). NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.)

The ECU uses the exhaust manifold pressure for the volumetric efficiency calculation. The exhaust manifold pressure sensor uses pin 27 for supply voltage, pin 11 for signal, and pin 25 for ground on engine control unit (ECU) connector 1 (X5501). NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.) For information on how pressure sensors operate, see Measuring Pressure. (CTM120119.)

Exhaust Gas Recirculation (EGR) Delta Pressure Sensor (B5103)—The exhaust gas recirculation (EGR) delta pressure sensor (B5103) measures the pressure drop across the EGR venturi tube. The ECU calculates the amount of the recirculated exhaust gas using this measurement and the venturi tube physical dimensions. The ECU controls the EGR valve (Y5400) and turbocharger actuator (Y5500) to recirculate the ideal amount of exhaust gas for the operating condition. The EGR delta pressure sensor uses pin 36 for supply voltage, pin 05 for signal, and pin 24 for ground on engine control unit (ECU) connector 2 (X5502).

NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.)

Manifold Air Temperature (MAT) Sensor (B5206)—The manifold air temperature (MAT) sensor (B5206) is used to measure the temperature of the air in the intake manifold. The ECU then compares the temperatures of the recirculated exhaust gas, charge air cooler outlet air, and mixed air in the intake manifold to determine if proper cooling and mixing has occurred. If the temperature is not correct, the ECU adjusts the signal going to the EGR valve (Y5400) to compensate the mixture. The MAT sensor helps the ECU calculate the correct fueling for the engine. The ECU also uses this sensor for engine protection purposes.

For information on how pressure sensors operate, see Measuring Pressure. (CTM120119.)

The MAT sensor uses pin 09 for signal and pin 15 for ground on engine control unit (ECU) connector 2 (X5502).

Inlet Fuel Pressure Sensor (B5107)—The inlet fuel pressure sensor (B5107) sends a pressure equivalent signal to the ECU. The ECU monitors fuel pressure to determine if fuel is continuously passing through the low-pressure side of the fuel system, or if there is a leak or blockage in it. Based on inlet fuel pressure sensor inputs, the ECU controls the low-pressure fuel pump speed to maintain the desired pressure.

NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.)

The crankcase pressure sensor uses pin 15 for supply voltage, pin 18 for signal, and pin 45 for ground on engine control unit (ECU) connector 2 (X5502).

For information on engine protection and derate programs, see Engine Derate and Shutdown Protection. (CTM120119.) Engine Coolant Temperature Sensor (B5208)—The engine coolant temperature sensor (B5208) monitors the coolant temperature for engine protection. Depending on the severity of the temperature increase, the ECU transmits a diagnostic trouble code (DTC) for either moderate or extreme temperature levels. The engine is derated for each level of temperature severity. When the ECU determines the coolant temperature is too low for the current operating conditions, it will set a DTC, indicating a thermostat is stuck open. The engine coolant temperature sensor uses pin 16 for signal and pin 50 for ground on engine control unit (ECU) connector 1 (X5501). NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.) For information on how temperature sensors operate, see Measuring Temperature. (CTM120119.)

The ECU uses the crankshaft position input to determine engine speed and the angular position of the crankshaft in its 360-degree field of rotation. The ECU also uses this signal to calculate engine (crankshaft) speed and sends this information across the controller area network (CAN) to the monitor controller (DSZ) (A4), where the information appears on the monitor display as engine rpm. Based on information from the crankshaft position and camshaft position sensors, the ECU calculates precisely to control the timing and duration of fuel injection. If there is a problem with the crankshaft position sensor, the ECU will use the camshaft position sensor to determine engine timing, which may require prolonged engine cranking to start the engine. The crankshaft position sensor uses pin 38 for signal and pin 30 for ground on engine control unit (ECU) connector 1 (X5501). Pin 35 of ECU connector 1 provides a shield for the signal and ground wires. NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.)

Fuel Temperature Sensor (B5209)—The fuel temperature sensor (B5209) input is used by the ECU to calculate fuel density and adjust fuel delivery.

Camshaft Position Sensor (B5302)—The camshaft position sensor (B5302) is used to determine engine speed and when each cylinder is at top dead center (TDC) of the compression stroke. The ECU uses this information to determine injection timing.

The fuel temperature sensor uses pin 48 for signal and pin 50 for ground on engine control unit (ECU) connector 1 (X5501). NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.) For information on how temperature sensors operate, see Measuring Temperature. (CTM120119.) For information on engine protection and derate programs, see Engine Derate and Shutdown Protection. (CTM120119.) NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.)

Camshaft position sensor consists of a permanent magnet, coil, and yoke. The sensor is mounted near the inner camshaft gear which contains seven webs. During engine rotation, an AC voltage pulse is induced in the coil as each web passes by the sensor. There are seven pulses per camshaft revolution. The circular distance between two of the webs is smaller. By detecting this difference, the ECU determines when cylinder number one is at TDC of its compression stroke. The camshaft speed signal circuit is shielded from electromagnetic interference (EMI). If there is a problem with the camshaft position sensor, the ECU will use the crankshaft position sensor to determine engine timing, which may require prolonged engine cranking to start the engine.

For information on how speed sensors operate, see Measuring Speed. (CTM120119.) For information on engine protection and derate programs, see Engine Derate and Shutdown Protection. (CTM120119.) Crankshaft Position Sensor (B5301)—The crankshaft position sensor (B5301) is an inductive-type pickup sensor that detects teeth on the crankshaft timing gear. The crankshaft timing gear is composed of 78 evenly spaced teeth. Two of the teeth are ground back 1/2 the width of the teeth from the front of the gear. These partially ground-off teeth help the ECU determine when cylinder number one or six is at top dead center (TDC) of its compression stroke.

The camshaft position sensor uses pin 28 for signal and pin 29 for ground on engine control unit (ECU) connector 1 (X5501). Pin 35 of ECU connector 1 provides a shield for the signal and ground wires. NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.)

For information on engine protection and derate programs, see Engine Derate and Shutdown Protection. (CTM120119.) Fan Speed Sensor (B5303)—The fan speed sensor (B5303) sends the engine control unit (ECU) with the fan speed in revolutions per minute (rpm). The ECU uses the fan speed sensor for more precise control of the fan speed. The fan speed sensor uses pin 36 for supply voltage on engine control unit (ECU) connector 2 (X5502). The fan speed sensor uses pin 53 for signal and pin 50 for ground on engine control unit (ECU) connector 1 (X5501). Intake Air Sensor (B5500)—The intake air sensor (B5500) measures temperature, pressure and humidity of the turbocharger compressor inlet air. The location of the measurements is in the intake prior to the fixed geometry turbocharger. The sensor communicates with the ECU over the engine CAN bus. These measurements provide input for fueling calculations made by the ECU. Humidity affects the exhaust gas temperature and the effectiveness of exhaust filter cleaning. The ECU compares turbocharger compressor inlet pressure to barometric air pressure to calculate the intake air pressure drop. The intake air sensor uses pin 28 for supply voltage and pin 14 for ground on engine control unit (ECU) connector 2 (X5502). The intake air sensor uses pins 45 and 46 for CAN communication on engine control unit (ECU) connector 1 (X5501). Pin 35 of ECU connector 1 provides a shield for the CAN wires. NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.)

Engine Coolant Loss Level Sensor (B5009)—The engine coolant loss level sensor (B5009) is a reed switch that extends from the bottom of the surge tank. A float in the tank changes position with coolant level. When the coolant level falls, the ring magnet on the bottom of the float moves to the bottom of the tank, below the switch position. The magnetic field is removed, the switch will open, a diagnostic trouble code (DTC) will be set, and the engine will be derated. The engine coolant loss level sensor uses pin 17 for signal and pin 14 for ground on engine control unit (ECU) connector 2 (X5502). NOTE: For component location, see Engine Interface Harness (W5) Component Location. (Group 9015-10.) Electronic Injectors (Y1—Y4)—The electronic injectors (Y1—Y4) are controlled by the engine control unit (ECU) for injection timing and amount of fuel, by energizing and de-energizing the electronic injectors. For more information on the electronic injectors, see Electronic Injector (EI) Operation. (CTM120119.) For information on CAN communication, see Controller Area Network (CAN) Theory of Operation.

Water-in-Fuel (WIF) Sensor (B5600)—The water-in-fuel (WIF) sensor (B5600) is located on the bottom of the primary fuel filter in the water separator bowl. When water is detected in the fuel, a signal is sent to the ECU. The water-in-fuel sensor uses the resistance of fuel and water in the fuel system along with the principle that water is a better conductor than fuel. If water is present, the voltage will be lower. The ECU monitors water in fuel for engine protection. The water-in-fuel sensor uses pin 15 signal and pin 50 for ground on engine control unit (ECU) connector 1 (X5501). NOTE: For component location, see Diesel Exhaust Fluid (DEF) Harness (W54) Component Location. (Group 9015-10.)

Water-in-Fuel Alarm— The engine control unit (ECU) (A1) monitors the water-in-fuel sensor (B5600) for water in the fuel. When water is present, the engine control unit will ground connector engine control unit (ECU) connector 2 (X5502) pin E2, grounding monitor controller (A4) pin C12. When monitor controller (A4) pin C12 is grounded, the monitor will display the water-in-fuel indicator to notify the operator of the water-in-fuel condition.

Suction Control Valve (Y5002)— The suction control valve (Y5002) is located on the high pressure fuel pump. The engine control unit (ECU) sends an electronic signal to the suction control valve through the solenoid to regulate the delivery of fuel to the high pressure common rail (HPCR). When the suction control valve is energized, fuel is allowed into the pumping chamber of the high pressure fuel pump. The pressurized fuel is then sent to the HPCR. The ECU varies the time of the signal to ensure the proper amount of fuel is available, see High-Pressure Fuel System Operation. (CTM120119.)

Fuel Rail Pressure Relief Valve (PRV) (Y5024)—The fuel rail pressure relief valve (Y5024) is located on the end of the high-pressure common rail (HPCR). The ECU sends a signal to the pressure relief valve solenoid to regulate the pressure in the HPCR. When the pressure relief valve is energized, fuel pressure in the HPCR is reduced by allowing the fuel to flow to the return manifold. The pressure relief valve works in conjunction with the high-pressure control valves on the high-pressure pump to control fuel pressure in the HPCR. The pressure relief valve is also energized at key OFF to relieve the fuel pressure in the HPCR. The fuel rail pressure relief valve uses pin 06 for supply voltage and pin 34 for ground on engine control unit (ECU) connector 1 (X5501). Pin 23 of ECU connector 1 provides a shield for the CAN wires. For more information on the high-pressure fuel system, see High-Pressure Fuel System Operation. (CTM120119.)

NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.) For additional information on the EGR valve, see EGR Valve Operation. (CTM120119.) Exhaust Throttle Actuator (Y5402)—The exhaust throttle actuator (Y5402) is located upstream of the intake manifold and is normally open. An electric motor opens and closes a butterfly valve. To raise the exhaust gas temperature before and during exhaust filter cleaning, the ECU commands the intake air throttle valve to close. The actual manifold air pressure may be negative if a vacuum develops in the intake manifold while the butterfly valve is closed. The ECU receives position feedback from a sensor located inside the intake air throttle assembly. The intake air throttle uses pin 17 for supply voltage, pin 36 for signal, and pin 41 for ground on engine control unit (ECU) connector 1 (X5501).

For information on CAN communication, see Controller Area Network (CAN) Theory of Operation. (Group 9015-15.) Exhaust Gas Recirculation (EGR) Valve (Y5400)—The exhaust gas recirculation (EGR) Valve (Y5400) reduces the amount of nitrogen oxides (NOx) emissions by diluting the intake air with exhaust gases by as much 10—12%. NOx emissions are formed when fuel is burned at high temperatures such as in the combustion process. The EGR valve functions only under high loads and when the engine coolant temperature sensor (B5208) is at normal operating temperature; otherwise, the valve remains closed. The ECU controls the EGR valve by calculating engine speed, load requirements, and inputs from various temperature and pressure sensors. The exhaust gas recirculation valve uses pin 27 for supply voltage, 52 for signal, and pin 25 for ground on engine control unit (ECU) connector 1 (X5501). The exhaust gas recirculation valve uses pins 07 and 08 for desired valve position on engine control unit (ECU) connector 1 (X5501).

The intake air throttle uses pins 10 and 12 for controlled valve position on engine control unit (ECU) connector 1 (X5501). NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.) For more information on the exhaust throttle actuator, see Exhaust Throttle Actuator. (CTM120119.) Fuel Transfer Pump (Y5501)—The fuel transfer pump (Y5501) draws fuel from the fuel tank through the fuel filter head and primary fuel filter. The fuel flows through the secondary fuel filter to the high-pressure fuel pump. For more information, see Electric Low-Pressure Fuel Pump Operation. (CTM120119.) The fuel transfer pump is supplied with power through engine control unit (ECU) pin 22 on engine control unit (ECU) connector 1 (X5501); ground is supplied through engine control unit (ECU) pin 14 on engine control unit (ECU) connector 1 (X5501).

If the ECU detects an incorrect position or a learned value error (EGR valve not controllable), the ECU will derate the Continued on next page

Engine Control Unit (ECU) (A1)—The engine control unit (ECU) uses information received from various sensors to determine the correct amount of fuel and injection timing based on load, temperatures, and operator input. Some of the data calculated by the ECU is transmitted across the controller area network (CAN) to the main controller (MCZ) (A3), monitor controller (DSZ) (A4), flex power controller (FPC) (A15), and modular telematics gateway (MTG) controller (A6000). The DSZ forwards much of the information across the CAN data line to the monitor where the information is displayed on the appropriate screen. NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.)

• For information concerning the MCZ, see Main

Controller (MCZ) Circuit Theory of Operation. (Group 9015-15.) • For information concerning the DSZ, see Monitor Controller (DSZ) Circuit Theory of Operation. (Group 9015-15.)

• Engine Mode The ECU contains a barometric air pressure (BAP) sensor that is located inside the ECU. This sensor is used to determine the pressure of the ambient air at the mounting location of the ECU. The BAP sensor helps the ECU determine the air density for calculating the correct air-fuel ratio. This sensor cannot be repaired or replaced without replacing the entire ECU. The ECU also contains a temperature sensor that is located inside the ECU. This sensor is used to determine the internal temperature of the ECU. If the ECU temperature exceeds specification, the ECU limits the speed of the engine in an attempt to protect the ECU from permanent damage. Temperature sensor cannot be repaired or replaced without replacing the entire ECU.

• Programming—The ECU can be programmed by

Whenever an engine DTC occurs, the information is captured or recorded. The information generated is called a Snapshot. The Snapshot information is categorized into two types: Snapshot Capture and Snapshot Recording. For more information, see Snapshot Instructions. (CTM120119.)

downloading the latest programs from the software delivery system (SDS). • Compression Test—This test is used to determine the relative compression of each cylinder. The engine is cranked while being provided with no fuel. The angular period of the crankshaft is measured near top dead center (TDC), and again past TDC. The periods can be converted to velocities, and the relative decelerations can be calculated from the difference in the velocities. The deceleration is a function of the pressure in the cylinder. By comparing the result from each cylinder, cylinders with relatively low compression can be identified. • Cylinder Cutout-Misfire Test—This test provides the capability to cutout fuel to individual cylinders and provide a programmable fuel command to the other cylinders for a programmable number of cylinder firing events. The total time for the number of firing events is determined and made available to Service ADVISOR™ for analysis. ECU Power Up (power and ground)—Unswitched battery power is available from:

• Fuse F36—Pins 23 and 24 of engine control unit (ECU) connector 3 (X5503).

• Fuse F37—Pins 13 and 14 of engine control unit (ECU) connector 3 (X5503).

Ground is provided at pin 22 via engine control unit (ECU) connector 2 (X5502) and pins 16, 17, 27, 43, and 44 via engine control unit (ECU) connector 3 (X5503). When key switch (S1) is in the ON position, current flows from pin M of key switch to pin 3 of key cut relay (K13) and through idle stop 5 A fuse (F18) to pin 1 of key cut relay. Utilizing the normally closed contacts of the key cut relay, current is passed to pin 7 of engine control unit (ECU) connector 3 (X5503) through power on 5 A fuse (F17), causing the ECU to power up. When key switch (S1) is in the START position, current flows from pin ST through the normally closed contacts of starter cut relay (K4) to starter relay (K34), energizing the relay. With the starter relay energized, power is supplied to pin S of starter motor (M1), thus cranking the engine. Once the ECU has determined the engine has started, pin 05 of engine control unit (ECU) connector 3 (X5503) is grounded, providing ground to starter cut relay, energizing the relay. With starter cut relay energized, the start signal is removed from the starter relay, de-energizing the starter relay, thus disengaging the starter motor. When the engine is running the ECU provides excitation from pin 34 of engine control unit (ECU) connector 2 (X5502) to pin D+ of the alternator (G3) for the charging circuit. For more information, see Starting and Charging Circuit Theory of Operation. (Group 9015-15.)

torque message is sent. Before applying a new torque command, the ECU verifies the watchdog indicator has changed from the previous message. If the ECU detects that the torque command message is not being updated at the expected rate or if two consecutive messages have the same watchdog indicator value, the ECU will default to the lowest torque curve and set the appropriate diagnostic trouble code (DTC). The FPC is used to monitor the system voltage. The FPC uses engine speed and system voltage data, received via CAN from the ECU, to determine the state of the alternator and battery. If the voltage is below a predefined threshold with the engine running, a DTC is created and a message is sent via CAN to the monitor controller (DSZ) (A4) to activate the alternator light on the monitor. The FPC interfaces with the modular telematics gateway (MTG) controller (A6000) and the monitor controller (DSZ) (A4) to communicate the availability of software updates for the machine controllers via Service ADVISOR™ Remote (SAR). The Service ADVISOR™ Remote (SAR) switch (S18) is used to accept or decline these updates. The FPC monitors the status of parked exhaust filter cleaning cycles. The FPC will generate a DTC to warn the operator of aborted cleaning cycles. The FPC stores the machine model information in nonvolatile memory. On each power cycle, the FPC compares the model received from the main controller (MCZ) (A3) to its own stored model data. If the two do not agree, the machine model can’t be verified and the flex power function will default to the low torque curve. Flex Power Controller (FPC) (Power and Ground)—Unswitched battery power is available at pins L1 and L2 of flex power controller (FPC) (A15) through fuel transfer pump and controllers 20 A fuse (marked ECU P4) (F38) and through flex power controller (FPC) in-line 10 A Fuse (F5004). Ground is provided at pin M2 and pin M3 of FPC.

Flex Power Controller (FPC) (A15)—The FPC provides several functions: flex power control, system voltage monitoring, Service ADVISOR™ Remote (SAR), and exhaust filter cleaning malfunction notice. FPC is used to allow the vehicle system to adjust the maximum available torque between two predefined torque curves. The flex power function allows the engine torque level to be defined via CAN by the FPC. However, the engine control unit (ECU) and FPC both contain a common data table defining the minimum and maximum torque at each speed within the operating range of the engine. The ECU updates the FPC with the current engine speed every 20 milliseconds. Once the FPC receives the engine speed, it then computes the new torque command for that speed as a percentage between the minimum and maximum torque values in the data table. Every 20 milliseconds, the FPC sends an updated torque command to the ECU which also includes a watchdog indicator, which is simply a counter that increments each time the

When key switch (S1) is in the ON position, current flows from pin M of key switch to pin 3 of key cut relay (K13) and through idle stop 5 A fuse (F18) to pin 1 of key cut relay. Utilizing the normally closed contacts of the key cut relay, current flows through power on 5 A fuse (F17) to pin M1 of FPC, causing the FPC to power up. NOTE: For power up of the other electronic controllers, see the theory of operation of specific component:

Service ADVISOR™ Remote (SAR) Switch (S18)—The Service ADVISOR™ Remote (SAR) switch (S18) allows the operator to accept or decline available updates. The flex power controller (FPC) (A15) will create DTCs under certain trigger conditions, which will send a message via CAN to the monitor controller (DSZ) (A4) to prompt the vehicle to display operator instructions on the monitor. When key switch (S1) is in the ON position, current flows from pin M of key switch to pin 3 of key cut relay (K13) and through idle stop 5 A fuse (F18) to pin 1 of key cut relay. Utilizing the normally closed contacts of the key cut relay, current is passed through power on 5 A fuse (F17) to pins 1, 7, and 10 of Service ADVISOR™ Remote (SAR) switch (S18). When the SAR switch is pressed to the ACCEPT position, current is sent through pin 3 of the SAR switch to pin C1 of FPC. Pin E3 of FPC, is then grounded, completing the circuit to pin 5 of the SAR switch, activating the ACCEPT (green) light emitting diode (LED). When the SAR switch is pressed to the DECLINE position, current is sent through pin 2 of the SAR switch to pin F2 of FPC. Pin F3 of FPC, is then grounded, completing the circuit to pin 4 of the SAR switch, activating the DECLINE (red) light emitting diode (LED). Cold Weather Starting Aid—Power is available to pin 3 of glow plug relay (K16) from glow plug 50 A fuse (F63). Ground is provided at pin 1 of glow plug relay and to glow plugs (R1—R4). When key switch (S1) is in the ON position, current flows from pin M of key switch to pin 3 of key cut relay (K13) and through idle stop 5 A fuse (F18) to pin 1 of key cut relay. Utilizing the normally closed contacts of the key cut relay, current is passed to pin 7 of engine control unit (ECU) connector 3 (X5503) through power on 5 A fuse (F17), causing the ECU to power up. The ECU now determines if the glow plugs need to be activated. If the ECU determines the glow plugs are necessary, power is

sent out pin 32 via engine control unit (ECU) connector 1 (X5501) to pin 2 of glow plug relay, energizing the relay. Power is sent to glow plugs and through glow plug resistor (R19) to engine control unit (ECU) connector 1 (X5501) pin 54. For more information on cold start aid, see Cold Weather Starting Aid. (Group 9010-05.) Hydraulic Variable Speed Fan—The variable speed fan cools the machine's systems by a hydraulic pump and motor controlled by a variable speed fan solenoid, providing machine efficiency and reducing fan noise levels by only operating the fan at the minimum speed necessary to cool the machine systems. The engine control unit (ECU) uses the following inputs to determine the proper fan speed:

• B22—Ambient air temperature sensor if air conditioner is ON via CAN.

• B40—Hydraulic oil temperature sensor via controller area network (CAN).

• B5205—Charge air cooler outlet temperature sensor at

pin 29 of engine control unit (ECU) connector 2 (X5502).

• B5208—Engine coolant temperature sensor at pin 16 of engine control unit (ECU) connector 1 (X5501).

• B5209—Fuel temperature sensor at pin 48 of engine control unit (ECU) connector 1 (X5501).

The input that requires the most cooling takes precedence over the other inputs and the fan is run at a speed sufficient to cool the warmest input. If any of the three temperature sensor inputs are invalid, the fan will run at maximum speed to ensure proper cooling. The maximum fan speed is limited to engine speed. Temperature thresholds and variable speed fan solenoid duty cycles (fan speeds) are preprogrammed into the ECU and cannot be changed. The variable speed fan solenoid (Y5014) is driven from engine control unit (ECU) pin 32 of engine control unit (ECU) connector 2 (X5502).

To protect the fan pump while operating in cold conditions, the ECU limits the fan speed according to the input from the hydraulic oil temperature sensor (B40). The ECU will increase the fan speed as hydraulic oil warms.

*When the air conditioner is ON and the ambient air temperature is over 15°C (60°F) the engine fan will increase to 1250 rpm. **The engine control unit measures the intake air temperature and adds a constant value to it at ambient temperatures above 25°C (77°F). In this application, the constant value is 27°C (80°F) above ambient air temperature when ambient air temperature is above 25°C (77°F). At temperatures below 25°C (77°F), the engine control unit uses the constant of 52°C (126°F) for the fan speed calculations. For example:

• at 20°C (68°F) ambient temperature, the ECU calculated temperature would be 52°C (126°F). • at 26°C (79°F) ambient temperature, the ECU calculated temperature would be 53°C (128°F). • at 30°C (86°F) ambient temperature, the ECU calculated temperature would be 57°C (135°F).

Hydraulic Variable Speed Fan Reversing Function (if equipped)—The hydraulic variable speed fan with reversing function controls the cooling capacity of the cooling package by varying the speed of the fan. The engine control unit (ECU) automatically controls the speed of the fan by monitoring the following:

• Engine Coolant Temperature • Hydraulic Oil Temperature • Fuel Temperature • Charge Air Cooler Outlet Temperature • Ambient Air Temperature • Air Conditioning State (On-Off)

communicates with the DSZ and ACF to set the A/C compressor value to OFF. The A/C compressor will be temporarily turned off until approximately 1 minute after the completion of a fan reversing cycle; at that time, the ECU will send communication to set the A/C compressor value to ON. For more information on the DSZ, see Monitor Controller (DSZ) Circuit Theory of Operation. (Group 9015-15.) NOTE: If a malfunction exists for any of the previously mentioned temperature sensors, the fan speed will go to full speed.

The engine coolant temperature sensor (B5208), fuel temperature sensor, and charge air cooler outlet temperature sensor (B5205) are hard wired to the engine control unit (ECU). The hydraulic oil temperature is hard wired to the main controller (MCZ) (A3) and continuously transmits information across the controller area network (CAN) to communicate with the ECU. For more information on the hydraulic oil temperature sensor, see Main Controller (MCZ) Circuit Theory of Operation. (Group 9015-15.) The air conditioner compressor clutch is hard wired to the air conditioner controller (ACF) and continuously transmits information via CAN to communicate with the monitor controller (DSZ), which then forwards the information via CAN to the ECU. During a reversing cycle, the ECU

The engine control unit (ECU) uses certain reference values in the form of look-up tables for each of the temperatures and the air conditioning state to determine the fan speed for each input. The ECU then selects the highest fan speed required and sends current out pin 32 of engine control unit (ECU) connector 2 (X5502) to variable speed fan solenoid (Y5014). Static ground is provided to variable speed fan solenoid at all times on pin 21 of engine control unit (ECU) connector 1 (X5501). The amount of current the ECU provides the variable speed fan solenoid is inversely dependent on the calculated fan speed and compared to a predefined look-up table. Zero current commands maximum fan speed. For hydraulic operation of the fan, see Fan Drive Hydraulic System Operation. (Group 9025-05.)

Sub-System Diagnostics

The reversing fan function reverses the fan direction to purge the cooling system of debris. The reversing fan function can be operated in manual or automatic mode via the reversing fan switch (S15). Unswitched power is provided from optional connector and reversing fan 20 A fuse (F6) to pin 3 of reversing fan switch (S15). The reversing fan function can be operated when the ECU determines that the following conditions are met:

• Engine speed is at least 1180 rpm. • Hydraulic oil temperature is greater than 12°C (54°F). • The high temperature lamp is off. See Exhaust Aftertreatment Circuit Theory of Operation. (Group 9015-15.) • Fan solenoid codes are not present in the monitor. • A reverse sequence is not in progress. NOTE: The reversing fan is inhibited for 7 seconds following a fan reversal cycle and only an ECU reset can interrupt a fan reverse cycle. The first automatic reverse cycle will begin 1 hour after key ON or an ECU reset. When the automatic reversing fan timer in the ECU reaches the preset interval or if manual mode is selected, the ECU begins the reversing sequence as follows: 1. The ECU increases the current to variable speed fan solenoid (Y5014) to slow the fan to minimum fan speed (approximately 350 rpm). 2. When fan speed is at minimum, the ECU sends current out pin 26 of engine control unit (ECU) connector 2 (X5502) to the reversing fan solenoid (Y5015), energizing the solenoid. The fan solenoid reverses the fan direction. 3. With the fan now operating in the reverse direction, the ECU decreases the current applied to the variable speed fan solenoid (Y5014) until maximum fan speed (approximately 1500 rpm) is reached. 4. The ECU operates the fan at maximum speed in reverse direction for approximately 15 seconds, then increases the variable speed fan solenoid current until the fan is at minimum speed. 5. When the fan slows to minimum speed, the ECU stops sending current to the reversing fan solenoid (Y5015), causing the fan to change back to forward direction. 6. With the fan operating in the forward direction, the ECU decreases the variable speed fan solenoid current until the normal operating fan speed is obtained. When an automatic reversing sequence is complete the ECU will start the automatic reversing fan timer according to the preset interval of 60 minutes. The reversing sequence cannot be activated again for approximately 1 minute. If the reversing fan is in the automatic mode when the manual mode is activated, the reversing fan timer is stopped and then started again after the reversing fan sequence is completed. When a manual reverse cycle is complete, the function returns to the automatic mode.

(MCZ) and sensors located on the engine. The ECU is supplied with unswitched power on engine control unit (ECU) connector 3 (X5503) pins 12 and 50 through engine control unit (ECU) 20 A fuse (marked ECU P1) (F8), pins 23 and 24 through engine control unit (ECU) 20 A fuse (marked ECU P2), and pins 13 and 14 through engine control unit (ECU) 20 A fuse (marked ECU P3). Ground is provided on engine control unit (ECU) connector 2 (X5502) pin 22 and engine control unit (ECU) connector 3 (X5503) pins 16, 17, 27, 43, and 44. The ECU is turned on by a power on 5 A fuse (F17) through pin 07 of engine control unit (ECU) connector 3 (X5503). The ECU communicates with the MCZ through a CAN (controller area network). CAN connects to ECU through pins 01, 02, and 21 of engine control unit (ECU) connector 3 (X5503). If there is a malfunction with the ECU or one of the sensor circuits it is connected to, the ECU will illuminate an indicator on the monitor controller (A4) to notify the operator of the problem. See Reading Diagnostic Trouble Codes With Monitor Display. (Group 9015-20.) See Reading Diagnostic Trouble Codes with Service ADVISOR™ Diagnostic Application. (Group 9015-20.) Engine Speed Control— The engine speed dial allows for manual adjustment of the engine speed through the main controller (MCZ) (A3) to the engine control unit (ECU) (A1). A variable voltage of 0—5 volts is sent from the engine speed dial to the MCZ. The MCZ uses this information along with the status of the power mode button, work mode switch, auto-idle switch, and information from the pressure sensors to create an engine speed output signal. The engine speed output signal from the MCZ is used by the ECU to set the engine speed. Power is supplied to pin 4 of cab harness-to-switch panel connector 3 (X29) to MCZ connector (X36) pin F25. Signal is sent from pin 5 of cab harness-to-switch panel connector 3 (X29) to MCZ connector (X34) pin D16. Ground is supplied on pin 6 of cab harness-to-switch panel connector 3 (X29) to pin F16 of MCZ connector X36. For information on auto-idle and power modes ECO, PWR, and H/P, see Engine Speed Control System Operation. (Group 9010-05.) Engine Warm-Up— When the coolant temperature is below 0°C (32°F), the engine control unit (ECU) (A1) will run the engine at 1200 rpm for 12 minutes to warm up the engine. After the 12 minute warm-up period, the engine will return to slow idle unless the main controller (MCZ) is requesting the warm-up routine for the hydraulic oil. When the hydraulic oil temperature is below 0°C (32°F), the MCZ sends a signal to ECU to increase engine speed to 1400 rpm for 15 minutes. For more information on auto warm-up control, see Engine Speed Control System Operation. (Group 9010-05.) Power Limiting— The engine control unit (ECU) (A1) has a built-in engine protection program. The ECU will derate the amount of fuel that is delivered to the engine when sensor inputs exceed normal operating ranges. For a list of these fault codes and derate percentages, see Engine Control Unit (ECU) Diagnostic Trouble Codes. (Group 9001-20.)

Exhaust Filter Parked Cleaning Switch (S16)—The exhaust filter parked cleaning switch (S16) allows the operator to perform a parked exhaust filter cleaning. With key switch (S1) in the ON position, current flows from pin M of key switch to pin 3 of key cut relay (K13) and through idle stop 5 A fuse (F18) to pin 1 of key cut relay. Utilizing the normally closed contacts of the key cut relay, current is passed through power on 5 A fuse (F17) to pin 1 of exhaust filter parked cleaning switch (S16). When the ECU has determined a parked exhaust filter cleaning is required, ground is provided to pin 5 of exhaust filter parked cleaning switch from pin 35 of engine control unit (ECU) connector 3 (X5503), completing the circuit and activating the light emitting diode (LED). When the exhaust filter parked cleaning switch is held for 3 seconds, pin 38 of engine control unit (ECU) connector 3 (X5503) is connected to ground, initiating the parked exhaust filter cleaning if all requirements are met. NOTE: For component location, see Exhaust Filter Parked Cleaning Switch Harness (W9) Component Location. (Group 9015-10.)

Battery Disconnect Indicator Light (E22)—The battery disconnect indicator light (E22) illuminates when the key switch is in the ON position and stays illuminated until it is safe to turn the battery disconnect switch (S91) to the OFF position. When the key switch is in the ON position the engine control unit (ECU) sends power from pin 30 of engine control unit (ECU) connector 3 (X5503) to the battery disconnect indicator light. When the key switch is turned to the OFF position, the ECU determines when the diesel exhaust fluid (DEF) system has purged the DEF fluid in the DEF lines. NOTE: For component location, see Engine Interface Harness (W5) Component Location. (Group 9015-10.) For more information on the DEF system, see Exhaust Aftertreatment Circuit Theory of Operation.

Fuel Rail Pressure Sensor (B5113)—The fuel rail pressure sensor (B5113) sends a pressure equivalent signal to the engine control unit (ECU). The ECU monitors fuel pressure to control the amount and timing of fuel being transferred from the high-pressure fuel pump to the high-pressure common rail (HPCR). The ECU uses this signal input to determine if fuel rail pressure is adequate for the current operating condition. The ECU will command more or less fuel from the high-pressure fuel pump by altering the signal to the high-pressure fuel pump pressure control valve (PCV) 1 (Y5022) and high-pressure fuel pump pressure control valve (PCV) 2 (Y5023). The ECU also uses this sensor to determine if there is an electronic injector problem by measuring the drop of pressure in the HPCR during each injection. The fuel rail pressure sensor is used for engine protection. The fuel rail pressure sensor uses pin 37 for supply voltage, pin 09 for ground, and pin 51 for signal on engine control unit (ECU) connector 1 (X5501). NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.)

For information on engine protection and derate programs, see Engine Derate and Shutdown Protection. (CTM120119.) Engine Oil Pressure Sensor (B5101)—The engine oil pressure sensor (B5101) sends an oil pressure equivalent signal to the engine control unit (ECU). The ECU uses this signal to determine if engine oil pressure is adequate for the current operating conditions. The ECU monitors oil pressure for engine protection purposes. The engine oil pressure sensor uses pin 17 for supply voltage, pin 26 for signal, and pin 41 for ground on engine control unit (ECU) connector 1 (X5501).

Exhaust Manifold Pressure Sensor (B5102)—The exhaust manifold pressure sensor (B5102) provides feedback to the control systems for the exhaust throttle actuator (Y5402) and exhaust gas recirculation (EGR) valve (Y5400) in order to maximize engine performance while meeting the applicable emissions regulations. The ECU uses the exhaust manifold pressure for the volumetric efficiency calculation. The exhaust manifold pressure sensor uses pin 27 for supply voltage, pin 11 for signal, and pin 25 for ground on engine control unit (ECU) connector 1 (X5501). NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.) For information on how pressure sensors operate, see Measuring Pressure. (CTM120119.)

Exhaust Gas Recirculation (EGR) Delta Pressure Sensor (B5103)—The exhaust gas recirculation (EGR) delta pressure sensor (B5103) measures the pressure drop across the EGR venturi tube. The ECU calculates the amount of the recirculated exhaust gas using this measurement and the venturi tube physical dimensions. The ECU controls the EGR valve (Y5400) and turbocharger actuator (Y5500) to recirculate the ideal amount of exhaust gas for the operating condition. The EGR delta pressure sensor uses pin 36 for supply voltage, pin 05 for signal, and pin 24 for ground on engine control unit (ECU) connector 2 (X5502).

Crankcase Pressure Sensor (B5105)—The crankcase pressure sensor (B5105) is used to measure the amount of pressure in the crankcase of the engine. The ECU uses the crankcase pressure sensor value to indicate when the crankcase ventilation filter needs to be replaced or if there is a problem with the crankcase pressure relief valve that is located in the rocker arm cover.

Manifold Air Temperature (MAT) Sensor (B5206)—The manifold air temperature (MAT) sensor (B5206) is used to measure the temperature of the air in the intake manifold. The ECU then compares the temperatures of the recirculated exhaust gas, charge air cooler outlet air, and mixed air in the intake manifold to determine if proper cooling and mixing has occurred. If the temperature is not correct, the ECU adjusts the signal going to the EGR valve (Y5400) to compensate the mixture. The MAT sensor helps the ECU calculate the correct fueling for the engine. The ECU also uses this sensor for engine protection purposes.

For information on how pressure sensors operate, see Measuring Pressure. (CTM120119.)

The MAT sensor uses pin 09 for signal and pin 15 for ground on engine control unit (ECU) connector 2 (X5502).

Inlet Fuel Pressure Sensor (B5107)—The inlet fuel pressure sensor (B5107) sends a pressure equivalent signal to the ECU. The ECU monitors fuel pressure to determine if fuel is continuously passing through the low-pressure side of the fuel system, or if there is a leak or blockage in it. Based on inlet fuel pressure sensor inputs, the ECU controls the low-pressure fuel pump speed to maintain the desired pressure.

NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.)

The crankcase pressure sensor uses pin 15 for supply voltage, pin 18 for signal, and pin 45 for ground on engine control unit (ECU) connector 2 (X5502).

For information on engine protection and derate programs, see Engine Derate and Shutdown Protection. (CTM120119.) Engine Coolant Temperature Sensor (B5208)—The engine coolant temperature sensor (B5208) monitors the coolant temperature for engine protection. Depending on the severity of the temperature increase, the ECU transmits a diagnostic trouble code (DTC) for either moderate or extreme temperature levels. The engine is derated for each level of temperature severity. When the ECU determines the coolant temperature is too low for the current operating conditions, it will set a DTC, indicating a thermostat is stuck open. The engine coolant temperature sensor uses pin 16 for signal and pin 50 for ground on engine control unit (ECU) connector 1 (X5501). NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.) For information on how temperature sensors operate, see Measuring Temperature. (CTM120119.)

The ECU uses the crankshaft position input to determine engine speed and the angular position of the crankshaft in its 360-degree field of rotation. The ECU also uses this signal to calculate engine (crankshaft) speed and sends this information across the controller area network (CAN) to the monitor controller (DSZ) (A4), where the information appears on the monitor display as engine rpm. Based on information from the crankshaft position and camshaft position sensors, the ECU calculates precisely to control the timing and duration of fuel injection. If there is a problem with the crankshaft position sensor, the ECU will use the camshaft position sensor to determine engine timing, which may require prolonged engine cranking to start the engine. The crankshaft position sensor uses pin 38 for signal and pin 30 for ground on engine control unit (ECU) connector 1 (X5501). Pin 35 of ECU connector 1 provides a shield for the signal and ground wires. NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.)

Fuel Temperature Sensor (B5209)—The fuel temperature sensor (B5209) input is used by the ECU to calculate fuel density and adjust fuel delivery.

Camshaft Position Sensor (B5302)—The camshaft position sensor (B5302) is used to determine engine speed and when each cylinder is at top dead center (TDC) of the compression stroke. The ECU uses this information to determine injection timing.

The fuel temperature sensor uses pin 48 for signal and pin 50 for ground on engine control unit (ECU) connector 1 (X5501). NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.) For information on how temperature sensors operate, see Measuring Temperature. (CTM120119.)

(Group 9015-10.)

Camshaft position sensor consists of a permanent magnet, coil, and yoke. The sensor is mounted near the inner camshaft gear which contains seven webs. During engine rotation, an AC voltage pulse is induced in the coil as each web passes by the sensor. There are seven pulses per camshaft revolution. The circular distance between two of the webs is smaller. By detecting this difference, the ECU determines when cylinder number one is at TDC of its compression stroke. The camshaft speed signal circuit is shielded from electromagnetic interference (EMI). If there is a problem with the camshaft position sensor, the ECU will use the crankshaft position sensor to determine engine timing, which may require prolonged engine cranking to start the engine.

For information on how speed sensors operate, see Measuring Speed. (CTM120119.) For information on engine protection and derate programs, see Engine Derate and Shutdown Protection. (CTM120119.) Crankshaft Position Sensor (B5301)—The crankshaft position sensor (B5301) is an inductive-type pickup sensor that detects teeth on the crankshaft timing gear. The crankshaft timing gear is composed of 78 evenly spaced teeth. Two of the teeth are ground back 1/2 the width of the teeth from the front of the gear. These partially ground-off teeth help the ECU determine when cylinder number one or six is at top dead center (TDC) of its compression stroke.

The camshaft position sensor uses pin 28 for signal and pin 29 for ground on engine control unit (ECU) connector 1 (X5501). Pin 35 of ECU connector 1 provides a shield for the signal and ground wires. NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.)

For information on engine protection and derate programs, see Engine Derate and Shutdown Protection. (CTM120119.) Fan Speed Sensor (B5303)—The fan speed sensor (B5303) sends the engine control unit (ECU) with the fan speed in revolutions per minute (rpm). The ECU uses the fan speed sensor for more precise control of the fan speed. The fan speed sensor uses pin 36 for supply voltage on engine control unit (ECU) connector 2 (X5502). The fan speed sensor uses pin 53 for signal and pin 50 for ground on engine control unit (ECU) connector 1 (X5501). Intake Air Sensor (B5500)—The intake air sensor (B5500) measures temperature, pressure and humidity of the turbocharger compressor inlet air. The location of the measurements is in the intake prior to the fixed geometry turbocharger. The sensor communicates with the ECU over the engine CAN bus. These measurements provide input for fueling calculations made by the ECU. Humidity affects the exhaust gas temperature and the effectiveness of exhaust filter cleaning. The ECU compares turbocharger compressor inlet pressure to barometric air pressure to calculate the intake air pressure drop. The intake air sensor uses pin 28 for supply voltage and pin 14 for ground on engine control unit (ECU) connector 2 (X5502). The intake air sensor uses pins 45 and 46 for CAN communication on engine control unit (ECU) connector 1 (X5501). Pin 35 of ECU connector 1 provides a shield for the CAN wires. NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.)

Engine Coolant Loss Level Sensor (B5009)—The engine coolant loss level sensor (B5009) is a reed switch that extends from the bottom of the surge tank. A float in the tank changes position with coolant level. When the coolant level falls, the ring magnet on the bottom of the float moves to the bottom of the tank, below the switch position. The magnetic field is removed, the switch will open, a diagnostic trouble code (DTC) will be set, and the engine will be derated. The engine coolant loss level sensor uses pin 17 for signal and pin 14 for ground on engine control unit (ECU) connector 2 (X5502). NOTE: For component location, see Engine Interface Harness (W5) Component Location. (Group 9015-10.) Electronic Injectors (Y1—Y4)—The electronic injectors (Y1—Y4) are controlled by the engine control unit (ECU) for injection timing and amount of fuel, by energizing and de-energizing the electronic injectors. For more information on the electronic injectors, see Electronic Injector (EI) Operation. (CTM120119.) For information on CAN communication, see Controller Area Network (CAN) Theory of Operation.

For information on CAN communication, see Controller Area Network (CAN) Theory of Operation. (Group 9015-15.) Water-in-Fuel (WIF) Sensor (B5600)—The water-in-fuel (WIF) sensor (B5600) is located on the bottom of the primary fuel filter in the water separator bowl. When water is detected in the fuel, a signal is sent to the ECU. The water-in-fuel sensor uses the resistance of fuel and water in the fuel system along with the principle that water is a better conductor than fuel. If water is present, the voltage will be lower. The ECU monitors water in fuel for engine protection. The water-in-fuel sensor uses pin 15 signal and pin 50 for ground on engine control unit (ECU) connector 1 (X5501). NOTE: For component location, see Diesel Exhaust Fluid (DEF) Harness (W54) Component Location. (Group 9015-10.)

Water-in-Fuel Alarm— The engine control unit (ECU) (A1) monitors the water-in-fuel sensor (B5600) for water in the fuel. When water is present, the engine control unit will ground connector engine control unit (ECU) connector 2 (X5502) pin E2, grounding monitor controller (A4) pin C12. When monitor controller (A4) pin C12 is grounded, the monitor will display the water-in-fuel indicator to notify the operator of the water-in-fuel condition.

Suction Control Valve (Y5002)— The suction control valve (Y5002) is located on the high pressure fuel pump. The engine control unit (ECU) sends an electronic signal to the suction control valve through the solenoid to regulate the delivery of fuel to the high pressure common rail (HPCR). When the suction control valve is energized, fuel is allowed into the pumping chamber of the high pressure fuel pump. The pressurized fuel is then sent to the HPCR. The ECU varies the time of the signal to ensure the proper amount of fuel is available, see High-Pressure Fuel System Operation. (CTM120119.)

Sub-System Diagnostics

Fuel Rail Pressure Relief Valve (PRV) (Y5024)—The fuel rail pressure relief valve (Y5024) is located on the end of the high-pressure common rail (HPCR). The ECU sends a signal to the pressure relief valve solenoid to regulate the pressure in the HPCR. When the pressure relief valve is energized, fuel pressure in the HPCR is reduced by allowing the fuel to flow to the return manifold. The pressure relief valve works in conjunction with the high-pressure control valves on the high-pressure pump to control fuel pressure in the HPCR. The pressure relief valve is also energized at key OFF to relieve the fuel pressure in the HPCR. The fuel rail pressure relief valve uses pin 06 for supply voltage and pin 34 for ground on engine control unit (ECU) connector 1 (X5501). Pin 23 of ECU connector 1 provides a shield for the CAN wires. For more information on the high-pressure fuel system, see High-Pressure Fuel System Operation. (CTM120119.) NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.) For information on CAN communication, see Controller Area Network (CAN) Theory of Operation. (Group 9015-15.) Exhaust Gas Recirculation (EGR) Valve (Y5400)—The exhaust gas recirculation (EGR) Valve (Y5400) reduces the amount of nitrogen oxides (NOx) emissions by diluting the intake air with exhaust gases by as much 10—12%. NOx emissions are formed when fuel is burned at high temperatures such as in the combustion process. The EGR valve functions only under high loads and when the engine coolant temperature sensor (B5208) is at normal operating temperature; otherwise, the valve remains closed. The ECU controls the EGR valve by calculating engine speed, load requirements, and inputs from various temperature and pressure sensors. The exhaust gas recirculation valve uses pin 27 for supply voltage, 52 for signal, and pin 25 for ground on engine control unit (ECU) connector 1 (X5501). The exhaust gas recirculation valve uses pins 07 and 08 for desired valve position on engine control unit (ECU) connector 1 (X5501).

NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.) For additional information on the EGR valve, see EGR Valve Operation. (CTM120119.) Exhaust Throttle Actuator (Y5402)—The exhaust throttle actuator (Y5402) is located upstream of the intake manifold and is normally open. An electric motor opens and closes a butterfly valve. To raise the exhaust gas temperature before and during exhaust filter cleaning, the ECU commands the intake air throttle valve to close. The actual manifold air pressure may be negative if a vacuum develops in the intake manifold while the butterfly valve is closed. The ECU receives position feedback from a sensor located inside the intake air throttle assembly. The intake air throttle uses pin 17 for supply voltage, pin 36 for signal, and pin 41 for ground on engine control unit (ECU) connector 1 (X5501). The intake air throttle uses pins 10 and 12 for controlled valve position on engine control unit (ECU) connector 1 (X5501). NOTE: For component location, see Engine Harness (W4) Component Location. (Group 9015-10.) For more information on the exhaust throttle actuator, see Exhaust Throttle Actuator. (CTM120119.) Fuel Transfer Pump (Y5501)—The fuel transfer pump (Y5501) draws fuel from the fuel tank through the fuel filter head and primary fuel filter. The fuel flows through the secondary fuel filter to the high-pressure fuel pump. For more information, see Electric Low-Pressure Fuel Pump Operation. (CTM120119.) The fuel transfer pump is supplied with power through engine control unit (ECU) pin 22 on engine control unit (ECU) connector 1 (X5501); ground is supplied through engine control unit (ECU) pin 14 on engine control unit (ECU) connector 1 (X5501).

If the ECU detects an incorrect position or a learned value error (EGR valve not controllable), the ECU will derate the JL58967,0000742 -19-01JUN17-28/28

• Engine control unit (ECU) (A1) • Monitor controller (DSZ) (A4)

• For more information on the parked cleaning process, see Exhaust Filter. (Operator's Manual.)

The ECU controls engine and exhaust aftertreatment systems. The ECU communicates directly with the DSZ over the controller area network (CAN). The DSZ retains all of the monitor software and communicates directly with the monitor to display various screens and readings for exhaust aftertreatment. For more information on the CAN, ECU, and DSZ:

• See Controller Area Network (CAN) Theory of Operation. (Group 9015-15.) Operation. (Group 9015-15.)

Service Cleaning: This process requires activation by the service technician when exhaust filter restriction reaches the SERVICE level. This process is similar to parked cleaning, but requires at least 3 hours to complete. For information on the service cleaning process, see Exhaust Filter No. (Group 9015-16.) Also, see Service Regeneration Instructions. (CTM120119.)

Exhaust Filter Delta Pressure Sensor (B5109)—The exhaust filter delta pressure sensor (B5109) measures the differential pressure between the inlet and outlet of the diesel particulate filter (DPF). Differential pressure across the DPF is an indication of accumulated soot quantity. DPF regeneration is required when there is a high differential pressure. The ECU uses this measurement to determine when regeneration is complete. The exhaust filter delta pressure sensor uses two pressure sensors that are connected by hard lines:

Exhaust Filter Temperature Module (B5204)—The exhaust filter temperature module (B5204) measures temperatures in the exhaust filter and communicates with the ECU over the local interconnect network (LIN) to determine inputs for in-cylinder fuel dosing. The exhaust filter temperature module contains three temperature sensors that are mounted in the exhaust filter:

• Diesel oxidation catalyst (DOC) inlet temperature

valve that is located immediately after the turbocharger, located upstream of the intake manifold. An electric motor opens and closes a butterfly valve. To raise the exhaust gas temperature before and during exhaust filter cleaning, the ECU commands the intake air throttle valve to close. For more information on the intake air throttle, see Engine Control Unit (ECU) Circuit Theory of Operation. (Group 9015-15.)

sensor (B5201) is used to determine when temperature is high enough for in-cylinder fuel dosing to occur. • Diesel oxidation catalyst (DOC) outlet temperature sensor (B5202) is used to provide regeneration and fuel dosing feedback to the ECU. • Selective catalytic reduction (SCR) inlet temperature sensor (B5216) is used by the ECU to determine when temperature is high enough for DEF injection to occur.

Abort Conditions for Auto Cleaning—Exhaust aftertreatment abort conditions are monitored by the ECU. Auto cleaning is aborted when the ECU detects any of the following:

The exhaust filter temperature module (B5204) receives supply voltage on pin 1 from pin 6 of engine control unit (ECU) connector 2 (X5502), ground on pin 2 from pin 24 of ECU connector 2, and signal on pin 4 from pin 38 of ECU connector 2. The exhaust filter temperature module uses pin 3 is for communication over the LIN bus to pin 28 of ECU connector 2.

Abort Conditions for Parked or Service Filter Cleaning—Exhaust aftertreatment abort conditions are monitored by the ECU. If the auto-shutdown feature is enabled, the machine will shut down if an abort is detected.

Selective Catalytic Reduction (SCR) and Diesel Exhaust Fluid (DEF) System—The selective catalytic reduction (SCR) and diesel exhaust fluid (DEF) system on 4045HT76 engines are required to reduce NOx emissions generated by the engine. The aftertreatment SCR and DEF system uses the following major components: Diesel Exhaust Fluid (DEF) Tank Header Assembly (A5507)—The diesel exhaust fluid (DEF) tank header assembly (A5507) routes DEF into and out of the DEF tank. The header is equipped with a DEF tank level sensor (B5601), DEF tank temperature sensor (B5211), DEF tank header A (A5507A) 6-pin connector, and coolant control valve (Y5019). The DEF tank level sensor (B5601) uses pin 3 for signal on pin 49 of engine control unit (ECU) connector 2 (X5502). The DEF tank temperature sensor (B5211) uses pin 5 for signal on pin 19 of ECU connector 2. Both sensors are grounded on pin 4 from pin 48 of ECU connector 2. DEF tank header A is also equipped with coolant tubes from the engine cooling system. When the temperature of the DEF is below a predetermined threshold, the ECU grounds the coolant control valve (Y5019) on pin 2 from pin 51 of ECU connector 2 and sends a signal to pin 1 from pin 20 of ECU connector 2, energizing the solenoid and causing the coolant control valve (Y5019) to open. Coolant then flows through the DEF tank header until the DEF temperature rises above the predetermined threshold and the ECU de-energizes the solenoid.

(Group 9015-10.) • To purge the DEF tank header cooling system, see DEF Header Coolant Purge Test. (CTM120119.) Diesel Exhaust Fluid (DEF) Dosing Unit (B5501)—The diesel exhaust fluid (DEF) dosing unit (B5501) is an electrically controlled system for the delivery of DEF. The DEF dosing unit uses internal components to control

priming, pressure, shutdown sequence, and heating of the DEF within the DEF dosing unit. The DEF dosing unit interfaces with DEF tank header assembly (A5507). When the ECU activates the DEF dosing unit, the internal DEF pump draws DEF through the supply line from DEF tank header assembly (A5507) to the DEF dosing injector (Y5020). The priming pump receives power on pin 9 from pin 21 of engine control unit (ECU) connector 2 (X5502), ground on pin 8 from pin 31 of ECU connector 2, and signal on pin 10 from pin 25 of ECU connector 2. The DEF dosing unit pressure sensor receives power on pin 2 from pin 6 of engine control unit (ECU) connector 2 (X5502), ground on pin 4 from pin 43 of ECU connector 2, and signal on pin 3 from pin 46 of ECU connector 2. During a key-off event, the ECU opens the valve on the diesel exhaust fluid (DEF) dosing injector (Y5020). The ECU also grounds the DEF dosing unit reversing valve on pin 11 from pin 40 of engine control unit (ECU) connector 2 and sends power to pin 12 from pin 53 of ECU connector 2, energizing the reversing valve solenoid. The DEF is then drawn from the injector pressure line and routed back to the DEF tank through the return line. The remaining DEF in the supply line is pumped to the DEF tank. During cold weather, the ECU monitors the DEF temperature. At a predetermined temperature, the ECU turns on the DEF dosing unit internal heater. The ECU sends power to pin 6 from pin 54 of engine control unit (ECU) connector 2 and grounds pin 5 to pin 52 of ECU connector 2. The heater ensures DEF is able to flow through the DEF dosing unit to allow priming and normal operations (the DEF dosing unit will not prime until the unit is defrosted).

Selective Catalytic Reduction (SCR) Inlet NOx Sensor (B5502)—The ECU communicates with the selective catalytic reduction (SCR) inlet NOx sensor (B5502) through the aftertreatment controller area network (CAN). Engine NOx output is measured using the aftertreatment inlet NOx sensor (B5217) prior to the SCR and this measurement is used by the ECU to determine a low SCR NOx conversion efficiency. If a high NOx emission condition exists, the ECU commands the DEF dosing unit (B5501) and DEF dosing injector (Y5020) to inject DEF into the exhaust stream to reduce NOx output. The SCR inlet NOx sensor incorporates a heater element powered by switched battery power and controlled by the ECU. The selective catalytic reduction (SCR) inlet NOx sensor receives switched battery power on pin 1 from pin 50 of engine control unit (ECU) connector 2 and ground on pins 3 and 4 from pin 16 of ECU connector 2. The ECU communicates with the SCR inlet NOx sensor on pins 5 and 6 from pins 35 and 44 of ECU connector 2.

Selective Catalytic Reduction (SCR) Outlet NOx Sensor (B5503)—The ECU communicates with the aftertreatment selective catalytic reduction (SCR) outlet NOx sensor through the aftertreatment controller area network (CAN) bus. Engine-catalyzed NOx output is measured using aftertreatment outlet NOx sensor (B5218) in the SCR outlet, and this measurement is used by the ECU to determine a low SCR NOx conversion efficiency. If a high NOx emission condition exists, the ECU commands the DEF dosing unit (B5501) and DEF dosing injector (Y5020) to inject DEF into the exhaust stream to reduce NOx output. The SCR inlet NOx sensor incorporates a heater element powered by switched battery power and controlled by the ECU. The selective catalytic reduction (SCR) outlet NOx sensor receives switched battery power on pin 1 from pin 50 of engine control unit (ECU) connector 2 and ground on pin 4 from pin 16 of ECU connector 2.

Diesel Exhaust Fluid (DEF) Dosing Unit Line Heaters (E5601, E5602, and E5603)—The diesel exhaust fluid (DEF) system utilizes electric DEF dosing unit line heaters for DEF lines. At cold temperatures, the ECU enables the electrical heaters in the DEF system to warm the DEF lines between DEF tank header A (A5507A) and the DEF dosing injector (Y5020). The heaters remain on until the ECU determines that the DEF is no longer frozen.

The DEF dosing injector receives power on pin 1 from pin 13 of engine control unit (ECU) connector 2 and ground on pin 2 from pin 1 of ECU connector 2, energizing the solenoid. The solenoid opens a valve, causing the injector to inject pressurized DEF supplied by the DEF dosing unit into the aftertreatment system.

System Overview—The exhaust aftertreatment system involves the following major components:

VERY HIGH. The process takes less than 45 minutes to complete.

• Engine control unit (ECU) (A1) • Monitor controller (DSZ) (A4)

• For more information on the parked cleaning process, see Exhaust Filter. (Operator's Manual.)

The ECU controls engine and exhaust aftertreatment systems. The ECU communicates directly with the DSZ over the controller area network (CAN). The DSZ retains all of the monitor software and communicates directly with the monitor to display various screens and readings for exhaust aftertreatment. For more information on the CAN, ECU, and DSZ:

• See Controller Area Network (CAN) Theory of Operation. (Group 9015-15.) Operation. (Group 9015-15.)

• See Monitor Controller (DSZ) Circuit Theory of

Service Cleaning: This process requires activation by the service technician when exhaust filter restriction reaches the SERVICE level. This process is similar to parked cleaning, but requires at least 3 hours to complete. For information on the service cleaning process, see Exhaust Filter No.(Group 9015-16.) Also, see Service Regeneration Instructions. (CTM120119.)

Exhaust Filter Delta Pressure Sensor (B5109)—The exhaust filter delta pressure sensor (B5109) measures the differential pressure between the inlet and outlet of the diesel particulate filter (DPF). Differential pressure across the DPF is an indication of accumulated soot quantity. DPF regeneration is required when there is a high differential pressure. The ECU uses this measurement to determine when regeneration is complete. The exhaust filter delta pressure sensor uses two pressure sensors that are connected by hard lines:

Operation. (Group 9015-15.)

There are four cleaning processes used to clean the exhaust filter:

• Passive cleaning • Auto cleaning • Parked cleaning • Service cleaning Passive and Auto Cleaning: These processes require no interaction from the operator.

• B5213—Diesel particulate filter (DPF) outlet pressure

When enabled, auto cleaning will activate when exhaust filter restriction is MODERATE or HIGH.

Exhaust Filter Temperature Module (B5204)—The exhaust filter temperature module (B5204) measures temperatures in the exhaust filter and communicates with the ECU over the local interconnect network (LIN) to determine inputs for in-cylinder fuel dosing. The exhaust filter temperature module contains three temperature sensors that are mounted in the exhaust filter:

• Diesel oxidation catalyst (DOC) inlet temperature

valve that is located immediately after the turbocharger, located upstream of the intake manifold. An electric motor opens and closes a butterfly valve. To raise the exhaust gas temperature before and during exhaust filter cleaning, the ECU commands the intake air throttle valve to close. For more information on the intake air throttle, see Engine Control Unit (ECU) Circuit Theory of Operation. (Group 9015-15.)

sensor (B5201) is used to determine when temperature is high enough for in-cylinder fuel dosing to occur. • Diesel oxidation catalyst (DOC) outlet temperature sensor (B5202) is used to provide regeneration and fuel dosing feedback to the ECU. • Selective catalytic reduction (SCR) inlet temperature sensor (B5216) is used by the ECU to determine when temperature is high enough for DEF injection to occur.

Abort Conditions for Auto Cleaning—Exhaust aftertreatment abort conditions are monitored by the ECU. Auto cleaning is aborted when the ECU detects any of the following:

The exhaust filter temperature module (B5204) receives supply voltage on pin 1 from pin 6 of engine control unit (ECU) connector 2 (X5502), ground on pin 2 from pin 24 of ECU connector 2, and signal on pin 4 from pin 38 of ECU connector 2. The exhaust filter temperature module uses pin 3 is for communication over the LIN bus to pin 28 of ECU connector 2.

Abort Conditions for Parked or Service Filter Cleaning—Exhaust aftertreatment abort conditions are monitored by the ECU. If the auto-shutdown feature is enabled, the machine will shut down if an abort is detected.

• DOC inlet or DOC outlet temperature is too low. • DOC outlet or DPF outlet temperature is too high. • Exhaust filter parked cleaning switch is pressed. • Component malfunction.

The ECU will abort the exhaust filter cleaning process and send an abort message to the DSZ if the following occurs:

• DOC inlet or DOC outlet temperature is too low. • DOC outlet or DPF outlet temperature is too high. • Removal of safe-state conditions.

- Throttle movement. - Pilot shutoff lever movement. • CAN communication lost from DSZ to ECU. • ECU unable to maintain exhaust temperatures. • Parked or service cleaning takes too long to either prepare the exhaust temperatures or clean the exhaust filter. • Exhaust temperatures too high. • Varying engine loads. • Component malfunction.

Selective Catalytic Reduction (SCR) and Diesel Exhaust Fluid (DEF) System—The selective catalytic reduction (SCR) and diesel exhaust fluid (DEF) system on 4045HT76 engines are required to reduce NOx emissions generated by the engine. The aftertreatment SCR and DEF system uses the following major components: Diesel Exhaust Fluid (DEF) Tank Header B (A5507B)—The diesel exhaust fluid (DEF) tank header B (A5507B) routes DEF into and out of the DEF tank. The header is equipped with a DEF tank level sensor (B5601), DEF tank temperature sensor (B5211), DEF tank concentration sensor (B5506), and DEF tank header B (A5507B) 4-pin connector. The ECU communicates with the diesel exhaust fluid (DEF) tank header B (A5507B) through the aftertreatment controller area network (CAN). The DEF tank header B receives switched battery power on pin 1 from pin 50 of engine control unit (ECU) connector 2 (X5502) and ground on pin 4 from pin 24 of ECU connector 2. The ECU communicates with the DEF tank header B on pins 2 and 3 from pins 35 and 44 of ECU connector 2. The DEF tank header B is also equipped with coolant tubes from the engine cooling system. When the temperature of the DEF is below a predetermined threshold, the ECU grounds the coolant control valve (Y5019) on pin 4 from pin 51 of ECU connector 2 and sends a signal to pin 1 from pin 20 of ECU connector 2, energizing the solenoid and causing the coolant control valve (Y5019) to open. Coolant then flows through the DEF tank header until the DEF temperature rises above the predetermined threshold and the ECU de-energizes the solenoid.

• For more information on DEF tank header B, see DEF Tank Header Operation. (CTM120119.)

• For more information on the DEF system component

location, see Diesel Exhaust Fluid (DEF) System Component Location. (Group 9010-05.) • For component location, see Diesel Exhaust Fluid (DEF) Harness (W54) Component Location. (Group 9015-10.) • To purge the DEF tank header cooling system, see DEF Header Coolant Purge Test. (CTM120119.) Diesel Exhaust Fluid (DEF) Dosing Unit (B5501)—The diesel exhaust fluid (DEF) dosing unit (B5501) is an

electrically controlled system for the delivery of DEF. The DEF dosing unit uses internal components to control priming, pressure, shutdown sequence, and heating of the DEF within the DEF dosing unit. The DEF dosing unit interfaces with DEF tank header B (A5507B). When the ECU activates the DEF dosing unit, the internal DEF pump draws DEF through the supply line from DEF tank header B (A5507B) to the diesel exhaust fluid (DEF) dosing injector (Y5020). The priming pump receives power on pin 9 from pin 21 of engine control unit (ECU) connector 2 (X5502), ground on pin 8 from pin 31 of ECU connector 2, and signal on pin 10 from pin 25 of ECU connector 2. The DEF dosing unit pressure sensor receives power on pin 2 from pin 6 of engine control unit (ECU) connector 2 (X5502), ground on pin 4 from pin 43 of ECU connector 2, and signal on pin 3 from pin 46 of ECU connector 2. During a key-off event, the ECU opens the valve on the diesel exhaust fluid (DEF) dosing injector (Y5020). The ECU also grounds the DEF dosing unit reversing valve on pin 11 from pin 40 of engine control unit (ECU) connector 2 and sends power to pin 12 from pin 53 of ECU connector 2, energizing the reversing valve solenoid. The DEF is then drawn from the injector pressure line and routed back to the DEF tank through the return line. The remaining DEF in the supply line is pumped to the DEF tank. During cold weather, the ECU monitors the DEF temperature. At a predetermined temperature, the ECU turns on the DEF dosing unit internal heater. The ECU sends power to pin 6 from pin 54 of engine control unit (ECU) connector 2 and grounds pin 5 to pin 52 of ECU connector 2. The heater ensures DEF is able to flow through the DEF dosing unit to allow priming and normal operations (the DEF dosing unit will not prime until the unit is defrosted).

• For operation of module, see DEF Dosing Unit Operation. (CTM120119.)

• For component location, see Diesel Exhaust Fluid (DEF) Harness (W54) Component Location. (Group 9015-10.)

Selective Catalytic Reduction (SCR) Inlet NOx Sensor (B5502)—The ECU communicates with the selective catalytic reduction (SCR) inlet NOx sensor (B5502) through the aftertreatment controller area network (CAN). Engine NOx output is measured using the aftertreatment inlet NOx sensor (B5217) prior to the SCR and this measurement is used by the ECU to determine a low SCR NOx conversion efficiency. If a high NOx emission condition exists, the ECU commands the DEF dosing unit (B5501) and DEF dosing injector (Y5020) to inject DEF into the exhaust stream to reduce NOx output. The SCR inlet NOx sensor incorporates a heater element powered by switched battery power and controlled by the ECU. The selective catalytic reduction (SCR) inlet NOx sensor receives switched battery power on pin 1 from pin 50 of engine control unit (ECU) connector 2 and ground on pins 3 and 4 from pin 16 of ECU connector 2. The ECU communicates with the SCR inlet NOx sensor on pins 5 and 6 from pins 35 and 44 of ECU connector 2.

• For component location, see Diesel Particulate Filter

(DPF) Harness (W62) Component Location. (Group 9015-10.) • For information on the aftertreatment CAN, see Controller Area Network (CAN) Theory of Operation. (Group 9015-15.) • For information on engine protection and derate programs, see Engine Derate and Shutdown Protection. (CTM120119.) Selective Catalytic Reduction (SCR) Outlet NOx Sensor (B5503)—The ECU communicates with the aftertreatment selective catalytic reduction (SCR) outlet NOx sensor through the aftertreatment controller area network (CAN) bus. Engine-catalyzed NOx output is measured using aftertreatment outlet NOx sensor (B5218) in the SCR outlet, and this measurement is used by the ECU to determine a low SCR NOx conversion efficiency. If a high NOx emission condition exists, the ECU commands the DEF dosing unit (B5501) and DEF dosing injector (Y5020) to inject DEF into the exhaust stream to reduce NOx output. The SCR inlet NOx sensor incorporates a heater element powered by switched battery power and controlled by the ECU. The selective catalytic reduction (SCR) outlet NOx sensor receives switched battery power on pin 1 from pin 50 of engine control unit (ECU) connector 2 and ground on pin 4 from pin 16 of ECU connector 2. The ECU communicates with the SCR inlet NOx sensor on pins 5 and 6 from pins 35 and 44 of ECU connector 2.

Harness (W53) Component Location. (Group 9015-10.)

• For information on engine protection and derate

programs, see Engine Derate and Shutdown Protection. (CTM120119.)

Diesel Exhaust Fluid (DEF) Dosing Unit Line Heaters (E5601, E5602, and E5603)—The diesel exhaust fluid (DEF) system utilizes electric DEF dosing unit line heaters for DEF lines. At cold temperatures, the ECU enables the electrical heaters in the DEF system to warm the DEF lines between DEF tank header B (A5507B) and the DEF dosing injector (Y5020). The heaters remain on until the ECU determines that the DEF is no longer frozen.

• Diesel exhaust fluid (DEF) dosing unit pressure line

heater (E5601) receives power on pin 1 from pin 10 of engine control unit (ECU) connector 2 and ground on pin 2 from pin 39 of ECU connector 2. • Diesel exhaust fluid (DEF) dosing unit supply line heater (E5602) receives power on pin 1 from pin 11 of engine control unit (ECU) connector 2 and ground on pin 2 from pin 42 of ECU connector 2. • Diesel exhaust fluid (DEF) dosing unit return line heater (E5603) receives power on pin 1 from pin 12 of engine control unit (ECU) connector 2 and ground on pin 2 from pin 41 of ECU connector 2.

• For component location, see Diesel Exhaust Fluid (DEF) Harness (W54) Component Location. (Group 9015-10.)

location, see Diesel Exhaust Fluid (DEF) System Component Location. (Group 9010-05.) • For information on engine protection and derate programs, see Engine Derate and Shutdown Protection. (CTM120119.) Diesel Exhaust Fluid (DEF) Dosing Injector (Y5020)—The diesel exhaust fluid (DEF) dosing injector (Y5020) is an electrically controlled, normally closed, coolant-cooled injector. The DEF dosing injector receives power on pin 1 from pin 13 of engine control unit (ECU) connector 2 and ground on pin 2 from pin 1 of ECU connector 2, energizing the solenoid. The solenoid opens a valve, causing the injector to inject pressurized DEF supplied by the DEF dosing unit into the aftertreatment system.

Main Controller Power Up (power and ground)—Unswitched battery power is available at pins E5 and E6 of the main controller (MCZ) (A3) through data converter and main controller battery power 5 A fuse (F10). Ground is provided to pins E1, E2, F4, F5, and F6 of the MCZ.

more power to boom up and arm in functions when hydraulic pump delivery pressure is high. The MCZ sends an engine speed request to the ECU via the CAN. The ECU monitors several sensors in the engine and makes adjustments to maintain the engine speed requested by the MCZ. For more information on CAN communication, see Controller Area Network (CAN) Theory of Operation. (Group 9015-15.) For more information on the ECU, see Engine Control Unit (ECU) Circuit Theory of Operation. (Group 9015-15.)

When key switch (S1) is in the ON position, current flows from pin M of key switch to pin 3 of key cut relay (K13). Utilizing the normally closed contacts of the key cut relay current is passed to pin E4 of the MCZ through power on 5 A fuse (F17), causing the MCZ to power up.

Engine Speed Dial (R15)—The engine speed dial (R15) controls the engine speed according to the rotation angle of the dial. The MCZ sends the equivalent to target engine speed to the engine control unit (ECU) via the controller area network (CAN).

Travel Mode (HP)—When the travel mode switch (S11) is set to fast (rabbit) speed, the switch grounds the MCZ at pin F8. The MCZ then activates the power dig/travel speed solenoid (marked SG) (Y24) depending on the status of the travel pressure sensor (marked TR) (B34), the front attachment pressure sensor (marked FRT) (B32), the pump control pressure sensors (B36 and B38), and the pump delivery pressure sensors (B35 and B37). The power dig/travel speed solenoid is a proportional solenoid controlled by pins A12 and A13 of the MCZ.

When battery relay (K19) is energized, current flows through solenoid 20 A fuse (F4) to pins F1, F2, and F3 of the MCZ.

Activation of the power dig/travel speed solenoid sends pilot pressure to the travel speed change valve in the travel motors. Pressure at the travel speed change valves changes the displacement of the travel motors allowing for fast travel speed. If the machine is traveling in fast travel speed and a dig or swing function is operated, the machine will remain in fast travel speed, but travel speed will slow as hydraulic oil is routed to other functions.

Sub-System Diagnostics temperature sensor (B40), located in the hydraulic oil tank. The MCZ will activate the warm-up circuit for 12 minutes or until the hydraulic oil temperature rises above 2°C (36°F).

When the travel mode switch is in the slow (turtle) speed position, the power dig/travel speed solenoid valve is de-energized. For more information, see Travel Motor Speed Circuit Operation. (Group 9025-05.) Power Dig—The power dig/travel speed solenoid (marked SG) (Y24) increases digging force by temporarily increasing the main hydraulic system relief pressure. The power dig switch (S7) grounds pin F11 of the MCZ. The MCZ then energizes the power dig/travel speed solenoid for a maximum of 8 seconds. The power dig/travel speed solenoid is a proportional solenoid and controlled by a pulse width modulated signal from pins A12 and A13 of the MCZ. When the power dig/travel speed solenoid is activated, pilot oil from the power dig/travel speed solenoid valve flows to the top of the main relief and power dig valve. The pilot oil pressure pushes the piston in the main relief and power dig valve down, increasing the pressure setting. The main hydraulic system now operates at the power dig operating pressure. For more information, see Main Relief Valve Circuit Operation. (Group 9025-05.) A/I (Auto-Idle) Mode—A/I (auto-idle) is a feature that reduces engine speed when hydraulic functions are not operated for more than 4 seconds. When the auto-idle switch (S8) is turned to A/I (auto-idle), the switch sends a ground to the MCZ to pin F7 of the MCZ. The MCZ communicates the selected mode through the CAN to the monitor controller (DSZ) (A4), updating the monitor with the current mode. When the engine speed dial is set to an engine speed above auto-idle speed, the MCZ will reduce the engine speed to auto-idle speed if hydraulic functions are not operated for more than 4 seconds. If engine speed dial is set to an engine speed below auto-idle speed, the engine speed will not increase or decrease after 4 seconds. The MCZ receives the pressure signal from the front attachment pressure sensor (marked FRT) (B32) or the travel pressure sensor (marked TR) (B34) to sense if a hydraulic function has been operated. For more information on CAN communication, see Controller Area Network (CAN) Theory of Operation. (Group 9015-15.) Cold Fluid Component Protection (CFCP)—CFCP protects components from damage by allowing engine coolant and hydraulic oil time to warm up in low temperatures if engine speed dial is set to high during start-up. After start-up, the CFCP icon on the monitor will illuminate until hydraulic oil temperature and engine coolant temperature conditions have been met. For more information, see Engine Speed Control System Operation. (Group 9010-05.) Hydraulic Oil Warm-Up Circuit—When hydraulic oil temperature is below 0°C (32°F), the MCZ activates a warm-up circuit, which raises the engine speed slightly above slow idle to help warm up the hydraulic oil. The MCZ receives oil temperature from the hydraulic oil

For more information on engine speed control, see Engine Speed Control System Operation. (Group 9010-05.) Engine Coolant Warm-Up Circuit—When engine coolant temperature is below predefined point, the MCZ activates a warm-up circuit, which raises the engine speed slightly above slow idle to help warm up the engine coolant. The MCZ receives coolant temperature via the CAN from the ECU. The MCZ will activate the warm-up circuit for 12 minutes or until the coolant temperature rises to 25°C (77°F). Idle Speed-Up Circuit—The idle speed-up circuit prevents the engine from hunting when travel or front attachment operation is performed while the engine is running at a speed between slow idle and idle speed-up speed. When the travel or front attachment operation is performed while the engine is between slow idle and idle speed-up speed, the MCZ sends the equivalent to target engine speed to the ECU via the CAN. The ECU then increases the engine speed to the idle speed-up speed. Pilot Shutoff Idle Speed-Up Circuit—When engine speed dial (R15) is in the slow idle position and the pilot shutoff lever is in the unlocked (DOWN) position, the MCZ activates the pilot shutoff idle speed up circuit. The MCZ sends the equivalent to target engine speed to the ECU via the CAN, which increases the engine speed by 100 rpm from the slow idle speed in order to prevent engine stall during a function. Engine Starting Idle Speed-Up Circuit—The engine starting idle speed-up circuit increases the engine speed and increases the engine oil pressure when the engine starts. The engine starting idle speed-up circuit will not activate if the engine speed dial (R15) is set above 1150 rpm. When active, the engine starting idle speed-up circuit sends the signals equivalent to the target engine speed to the ECU via the CAN. The idle speed-up circuit will remain active for 15 seconds. Engine speed will then return to the engine speed set by the engine speed dial. Travel Torque Up—The torque control solenoid (marked ST) (Y21) can be activated during a travel function. At slow engine speeds, the torque control solenoid is activated and both pumps are moved to maximum displacement. Maximum displacement of the pumps reduces the oil flow difference between the two hydraulic pumps and therefore reduces machine mistracking at low engine speeds. At fast engine speeds, the torque control solenoid may also be activated to slightly increase pump oil flow to improve the travel function. The torque control solenoid is a proportional solenoid and is controlled by a pulse width modulated signal from pins A2 and A3 of the MCZ. Auto-Shutdown Control—For more information on auto-shutdown control, see Starting and Charging Circuit Theory of Operation. (Group 9015-15.)

Work Modes—The DSZ contains several work modes that are communicated by the CAN to MCZ. The MCZ can adjust pump delivery and engine speed depending on the work mode or attachment selected. Pump flow and engine speeds can be adjusted with the monitor controller or by using MPDr. Hydraulic Oil Overheat Alarm Circuit—The hydraulic oil overheat alarm circuit sounds the monitor alarm when the hydraulic oil temperature increases beyond the specified value. The MCZ monitors hydraulic oil temperature utilizing hydraulic oil temperature sensor (B40). When hydraulic oil temperature increases and remains past a predefined point, the MCZ sends the signal to the DSZ via the CAN.

MCZ adjusts the signal to the torque control solenoid to change the pump displacement to utilize the maximum efficiency of the engine without allowing the engine to stall. The torque control solenoid is a proportional solenoid and is controlled by a pulse width modulated signal from pins A2 and A3 of the MCZ. Under most conditions, the torque control solenoid is activated to some degree. For more information, see Engine Speed Sensing Control Circuit Operation. (Group 9025-05.)

The monitor controller sounds the alarm and displays the hydraulic oil overheat alarm on the monitor. For more information, see Monitor Controller (DSZ) Circuit Theory of Operation. (Group 9015-15.)

Dig Regenerative Solenoid (marked SF) (Y22)—The dig regenerative solenoid valve (marked SF) (Y22) redirects oil from the boom cylinder rod end to the arm cylinder head end during a boom up and arm in function. This additional oil flow helps improve arm control and prevents arm cylinder cavitation during the combined function. The dig regenerative solenoid is a proportional solenoid that is controlled by a pulse width modulated signal from pins A14 and A15 of the MCZ.

Travel Alarm Circuit— For more information, see Travel Alarm Circuit Theory of Operation. (Group 9015-16.)

The MCZ activates the dig regenerative solenoid when the following conditions have been met:

Pump 2 Flow Rate Limit Solenoid (marked SB) (Y20)—The pump 2 flow rate limit solenoid (marked SB) (Y20) valve limits the pump 2 displacement according to each lever stroke of boom, arm, bucket, and travel in order to reduce fuel consumption. The pump 2 flow rate limit solenoid (marked SB) (Y20) is a proportional solenoid and is controlled by a pulse width modulated (PWM) signal from pins A6 and A7 of the main controller (MCZ). When the control lever is operated, the MCZ receives signals from the hydraulic pressure sensors and activates maximum pump 2 flow rate limit solenoid according to the sensor input. Fine adjustments to the pump 2 flow rate can be made through the monitor. NOTE: Flow rates and adjustments in MPDr and the monitor are approximate. Actual flow rates may vary. The auxiliary flow combiner may greatly affect MPDr flow adjustments if activated. Torque Control Solenoid (marked ST) (Y21)—The torque control solenoid (marked ST) (Y21) helps control pump displacement in response to changes in engine load. As engine load increases, the torque control solenoid is deactivated, reducing the pump displacement and therefore reducing engine load and prevents engine stall. As engine load decreases, the torque control solenoid is activated, increasing pump displacement and therefore increasing the efficiency of the machine. The MCZ monitors the difference between target engine speed as set by the MCZ and the actual engine speed as read by the ECU and communicated to the MCZ over CAN. As engine speed varies above or below target speed, the

For more information, see Dig Regenerative Valve Circuit Operation. (Group 9025-05.) Arm Regenerative Solenoid (marked SC) (Y23)—The arm regenerative solenoid (marked SC) (Y23) combines return oil from the arm cylinder rod end with supply oil to the arm cylinder head end. This additional oil flow helps prevent arm hesitation or cavitation in the arm in circuit during a combined arm in and swing or boom up function. The arm regenerative solenoid is a proportional solenoid that is controlled by a pulse width modulated signal from pins A10 and A11 of the MCZ. The MCZ activates the arm regenerative solenoid when the following conditions have been met:

• Either pump 1 delivery pressure sensor (marked PP1)

(B35) or pump 2 delivery pressure sensor (marked PP2) (B37) sensing low pressure • Arm in pressure sensor (marked PI2) (B31) sensing high pressure (arm in function fully actuated) • Swing pressure sensor (marked S3) (B33) or boom up pressure sensor (marked PI1) (B30) sensing pressure (swing or boom up function actuated)

When the arm regenerative solenoid is activated, pilot oil from the arm regenerative solenoid valve shifts the arm regenerative valve in the control valve. The arm regenerative valve blocks return oil from the arm cylinder rod end from returning to the hydraulic oil tank and combines the return oil with supply oil to the arm cylinder head end. Pilot oil from the arm regenerative solenoid valve also shifts the arm 2 flow rate control valve, limiting the oil to the second arm spool to preserve oil flow to other functions in the control valve. For more information, see Arm Regenerative Valve Circuit Operation and see Arm 2 Flow Rate Control Valve Circuit Operation. (Group 9025-05.) Power Dig/Travel Speed Solenoid (marked SG) (Y24)—The power dig/travel speed solenoid (marked SG) (Y24) increases digging force by temporarily increasing the main hydraulic system relief pressure. The power dig switch (S7) grounds pin F11 of the main controller (MCZ). The MCZ then energizes the power dig/travel speed solenoid (marked SG) (Y24) for a maximum of 8 seconds. The power dig/travel speed solenoid (marked SG) (Y24) is a proportional solenoid and is controlled by a pulse width modulated (PWM) signal from pins A12 and A13 of the MCZ. When the power dig/travel speed solenoid (marked SG) (Y24) is activated, pilot oil from the power dig/travel speed

solenoid (marked SG) (Y24) flows to the top of the main relief and power dig valve. The pilot oil pressure pushes the piston in the main relief and power dig valve down, increasing the pressure setting. The main hydraulic system now operates at the power dig higher operating pressure. For more information, see Main Relief Valve Circuit Operation. (Group 9025-05.) Pump 1 Flow Rate Limit Solenoid (marked SA) (Y26)—The pump 1 flow rate limit solenoid (marked SA) (Y26) limits the pump 1 displacement according to each lever stroke of boom, arm, bucket, and travel in order to reduce fuel consumption. The pump 1 flow rate limit solenoid is a proportional solenoid controlled by a pulse width modulated signal from pins A26 and A27 of the MCZ. When the control lever is operated, the MCZ receives signals from the hydraulic pressure sensors and activates maximum pump 1 flow rate limit solenoid according to the sensor input. Fine adjustments to the pump 1 flow rate can be made through the monitor. NOTE: Flow rates and adjustments in MPDr and the monitor are approximate. Actual flow rates may vary.

Auxiliary Function Lever (AFL)— The main controller (MCZ) provides control for AFL control. For more information on MCZ, see Main Controller (MCZ) Circuit Theory of Operation. (Group 9015-15.) Auxiliary hydraulic functions are controlled by the MCZ with inputs from the following components:

• B68—Secondary hydraulic oil temperature sensor • B85—Auxiliary function lever (AFL) solenoid pressure sensor (marked PS1)

• S29—Auxiliary function lever (AFL) proportional control switch

• S45—Auxiliary function enable switch (marked AFL_SW)

After the MCZ processes received input signals, output signals are sent to the solenoids to control hydraulic speed and volume with the following components:

• Y61—Auxiliary function lever (AFL) solenoid A (marked 1A)

• Y62—Auxiliary function lever (AFL) solenoid B (marked 1B)

• Y66—Secondary pilot shutoff solenoid valve (marked PiC)

cycle of the pilot control shutoff lever is done, AFL will need to be activated again. By pressing the auxiliary function enable switch (S45), ground is supplied at pin F22. The MCZ provides ground at pin C6, activating the secondary pilot shutoff solenoid valve (marked PiC) (Y66) which is a normally closed solenoid. When the operator actuates AFL proportional control switch (S29) on the right pilot control lever, a proportional signal is sent to the MCZ. The MCZ converts this signal and energizes the appropriate AFL solenoid to allow flow to the attachment in the requested speed and volume. The MCZ monitors secondary hydraulic oil temperature utilizing secondary hydraulic oil temperature sensor (B68) through pin C7 of the MCZ and grounded through pins F16 and F17 of the MCZ. When hydraulic oil temperature increases or decreases and remains past a predefined point, the MCZ sends the signal to the monitor controller (DSZ) (A4) via the controller area network (CAN). The MCZ monitors hydraulic oil pressure utilizing AFL solenoid pressure sensor through pin B2 of the MCZ and grounded through pins F25 and F26 of the MCZ. When hydraulic oil pressure increases and remains past a predefined point, the MCZ sends the signal to the monitor controller (DSZ) (A4) via the controller area network (CAN).

The machine controller (BCZ) (A11) receives unswitched power at pin A4 of machine controller 8-pin connector A (X10) from data converter and main controller battery power 5 A fuse (F10). Switched battery power is supplied to pin B19 of the BCZ through key cut relay (K13) with the key switch (S1) in the ON position. Switched power is also supplied to windshield wiper relay (K6) and windshield washer relay (K9). The BCZ is grounded at pin A8 of machine controller 8-pin connector A. The windshield wiper and washer circuit has four modes of operation:

• Windshield wiper ON (continuous) • Windshield wiper INT (intermittent) • Windshield wiper OFF (park) • Windshield wash Operation of the windshield wiper and washer circuit is controlled by signals from the BCZ and the state of the windshield wiper motor (M5) internal position status switch. Windshield Wiper Continuous Operation—When windshield wiper and washer switch (S9) is placed in the ON position, the BCZ grounds pin B9 at predetermined intervals. When pin B9 is grounded, the windshield wiper relay (K6) is energized. NOTE: Window switch (S28) must be connected for windshield wiper to operate. Power to windshield wiper motor (M5) is supplied from windshield wiper and washer 10 A fuse (F2). When windshield wiper relay is energized, pin L of the windshield wiper motor is grounded and the windshield wiper motor operates. The windshield wiper motor drives a pitman arm assembly which moves the windshield wiper blade back and forth across the windshield. When the windshield wiper is operating, the BCZ and monitor controller (DSZ) (A4) communicate through controller area network (CAN). The DSZ sends a signal to the monitor (A10) which displays the operation of the windshield wiper and washer switch. For more information on CAN theory of operation, see Controller Area Network (CAN) Theory of Operation. (Group 9015-15.)

position, BCZ intermittently grounds pin B9. The monitor controller (DSZ) (A4) controls windshield wiper delay time. NOTE: Window switch (S28) must be connected for windshield wiper to operate. Power to windshield wiper motor (M5) is supplied from windshield wiper and washer 10 A fuse (F2). When windshield wiper relay is energized, pin L of the windshield wiper motor is grounded, and the windshield wiper motor operates. The windshield wiper motor drives a pitman arm assembly which moves the windshield wiper blade back and forth across the windshield. When the windshield wiper is operating, the BCZ and DSZ communicate through controller area network (CAN). The DSZ sends a signal to the monitor (A10) which displays the operation of the windshield wiper and washer switch. For more information on CAN theory of operation, see Controller Area Network (CAN) Theory of Operation. (Group 9015-15.) Windshield Wiper Park Operation—When windshield wiper and washer switch (S9) is turned to the OFF position, windshield wiper motor (M5) continues to run until a cam-driven switch inside the windshield wiper assembly opens and removes power from the windshield wiper motor. The cam-driven switch applies ground to the windshield wiper motor pin S, causing the motor to run until a cam in the pitman arm assembly moves the windshield wiper to the left side of the windshield into the park position. When the windshield wiper motor reaches the park position, ground is removed from motor pin S by the internal switch, and the windshield wiper motor stops. Windshield Washer Operation—When windshield wiper and washer switch (S9) is pressed, the BCZ grounds pin A5. When pin A5 is grounded, the windshield washer relay (K9) is energized. Power is supplied to windshield washer motor (M6) from windshield wiper and washer 10 A fuse (F2) through pins 3 and 5 of energized windshield washer relay. The windshield washer motor drives the pump to spray fluid from the windshield washer fluid reservoir onto the windshield. When the windshield wiper and washer switch is released, ground is removed from pin A5 of BCZ and the washer motor stops. JS20420,0000D96 -19-23JAN18-2/2

The machine controller (BCZ) (A11) receives unswitched power at pin A4 of machine controller 8-pin connector A (X10) from data converter and main controller battery power 5 A fuse (F10). Switched battery power is supplied to pin B19 of the BCZ through key cut relay (K13) with the key switch (S1) in the ON position. The BCZ is grounded at pin A8 of machine controller 8-pin connector A. Work Light Operation—Turning the work light switch (S10) to position 1 activates the work light (E1). When key switch (S1) is in the ON position, current from pin M of the key switch is passed to pin 3 of key cut relay (K13). Utilizing the normally closed contacts of key cut relay, power is passed through power on 5 A fuse (F17) to pin 1 of work light relay (K7). When work light switch is in position 1, ground is supplied to pin A6 through work light 1 diode (V13) and to pin B7 of machine controller 20-pin connector B (X11). When work light relay is energized, the work light will illuminate. The BCZ communicates the work light switch position to the monitor controller (DSZ) (A4) via the controller area network (CAN). The DSZ then updates the monitor (A10) with the current work light operation. For more information on CAN theory of operation, see Controller Area Network (CAN) Theory of Operation. (Group 9015-15.)

relay, power is passed through load dump relay diode (V3) to energize the battery relay (K19) through pin S. The battery relay allows current to travel to the alternator B terminal through the alternator 65 A fuse (F60). At the B terminal of the alternator, current is then passed through the work and boom lights 20 A fuse (F1). Current then passes to boom light relay (K8) pins 1 and 3 and to work light relay (K7) pin 3. When work light switch is in position 2, ground is supplied to pins A2 and A6 of machine controller 8-pin connector A (X10) through work light 2 diode (V14) and to pin B17 of machine controller 20-pin connector B (X11). This energizes work light relay, boom light relay, cab roof light 1 relay, and cab roof light 2 relay and illuminates the work light, boom light, and cab roof lights 1—4. When key switch is turned to the OFF position, ground through pin A6 to work light relay is disconnected and work light turns off. With work light switch in position 2 and no ground detected from the key cut relay (K13), BCZ provides ground to pins A2 and A7, illuminating the boom light and key switch light for 30 seconds. After 30 seconds, the MCZ provides ground for the key cut relay through pin 5 cab harness-to-main controller 17-pin connector C. When current passes through key cut relay, power is removed from battery relay and current is removed from lights. The BCZ communicates the work light switch position to the monitor controller (DSZ) (A4) via the controller area network (CAN). The DSZ then updates the monitor (A10) with the current work light operation. For more information on CAN theory of operation, see Controller Area Network (CAN) Theory of Operation. (Group 9015-15.)

Boom Light Operation—Turning the work light switch (S10) to position 2 will activate the work light and boom light (E2). NOTE: When work light switch is in position 2, the monitor screen will change to nighttime mode screen. Daytime mode screen can be returned by pressing 0 on the keypad. When key switch (S1) is in the ON position, current from pin M of the key switch is passed to pin 3 of key cut relay (K13). Utilizing the normally closed contacts of key cut

The pilot shutoff circuit enables or disables (unlocks or locks) the pilot oil, thus enabling or disabling the machine hydraulics. The pilot shutoff circuit consists of the pilot shutoff switches 1 and 2 (S3 and S4), pilot shutoff switch diode (V20), pilot shutoff solenoid (Y10), pilot shutoff solenoid relay (K2), security relay (K5), monitor controller (DSZ) (A4), and security diode (V4). With key switch (S1) in the ON position, current flows from key switch pin M to key cut relay (K13). Utilizing the normally closed contacts of key cut relay, power is passed through pin 3 of key cut relay through power on 5 A fuse (F17) to monitor controller (A4) pin A16 and to battery relay (K19) pin S. With current at battery relay pin S the relay energizes closing the normally open contact sending current through alternator 65 A fuse (F60) and through solenoid 20 A fuse (F4) to pilot shutoff solenoid relay (K2), security relay (K5), and pilot shutoff solenoid (Y10). When the pilot shutoff lever is moved to the unlocked (DOWN) position, pin 10 of monitor controller 36-pin connector B (X21) detects a ground through pilot shutoff switch diode (V20), indicating that both pilot shutoff switches are in the same position, allowing the monitor to diagnose if there is a malfunction with one of the switches. When the pilot shutoff lever is in the unlocked (DOWN) position, ground passes through the pilot shutoff switches through starter cut relay diode (V5) to pilot shutoff solenoid relay, energizing the relay. When pilot shutoff solenoid relay is excited, the ground circuit in pilot shutoff solenoid (Y10) is connected to ground through pilot shutoff solenoid relay and security relay (K5), thus energizing the solenoid

allowing pressure oil from the pilot pump to be supplied to the pilot valve. When the pilot shutoff lever is in the unlocked (DOWN) position, ground is provided to the starter cut relay (K4) through starter cut relay diode (V5), energizing starter cut relay. When starter cut relay is energized, starter relay (K34) is de-energized, removing the start signal from starter motor (M1) and preventing the engine from cranking. For more information on the neutral engine start circuit, see Starting and Charging Circuit Theory of Operation. (Group 9015-15.) With the pilot shutoff lever in the unlocked (DOWN) position, ground is also provided to pin F13 of the main controller (MCZ) (A3), indicating the pilot shutoff lever is in the unlocked (DOWN) position. When the pilot shutoff lever is in the locked (UP) position, ground is not detected at pilot shutoff solenoid relay (K2). The relay remains de-energized, thus the pilot shutoff solenoid (Y10) is de-energized and the pilot hydraulics are disabled (locked). When the monitor security is active, pin D16 is grounded, energizing the starter cut relay (K4) and security relay (K5) through security diode (V4). Energized security relay removes ground to pilot shutoff solenoid relay (K2). When the pilot shutoff lever is in the unlocked (DOWN) position (pilot shutoff solenoid relay energized), the ground path to the pilot shutoff solenoid is broken, preventing the pilot hydraulics from being enabled (unlocked), keeping the machine from being operated when the security system is active.

Maximum Pump Flow—The maximum pump flow can be adjusted using MPDr, Service ADVISOR™, and the monitor. Adjustments made to pump flow are only approximate values. The machine is not designed to measure pump flow and therefore the values in MPDr, Service ADVISOR™, and the monitor are calculated approximations. Actual flow must be measured using a flowmeter to accurately adjust pump flow. See Pump Flow Test. (Group 9025-25.)

TX1088894A —UN—01MAR11

Pump 1 and pump 2 flow rates can be adjusted individually. If 2-speed is not selected (OFF), only pump 2 is used to run the attachment. In this mode, only adjustments to pump 2 will affect the flow to the attachment. Pump 2 flow rate adjustments are controlled by the main controller (MCZ) with the pump 2 flow rate limit solenoid. For more information, see Main Controller (MCZ) Circuit Theory of Operation. (Group 9015-15.) If 2-speed is selected (ON), both pumps 1 and 2 are used to run the attachment. With 2-speed ON, flow from pump 1 is combined with flow from pump 2 in the control valve. In this mode, both pumps may be adjusted to control the flow of the attachment. The monitor will display the combined flow rates of pump 1 and pump 2. See Service Menu. (Group 9015-16.) NOTE: The 2-speed will not work properly unless appropriate kits are installed on machine. Pump flow or flow priority may also be finely adjusted in the monitor. If 2-speed is not selected (OFF), small adjustments can be made to the pump 2 flow rate. Adjustments are only approximate and relative to the overall selected flow. Actual flow must be measured using a flowmeter to accurately set pump flow. If 2-speed is selected (ON), small adjustments can be made to the priority of oil flow. The priority can be adjusted to favor the attachment or the boom up, arm out, swing, and travel functions. Adjustments are only approximate and relative to the overall selected flow. Actual flow must be measured

Maximum Engine Speed—The maximum engine speed for an attachment may be adjusted using MPDr, Service ADVISOR™, and the monitor. The engine will reduce speed when a work mode with reduced engine speed is selected on the monitor. The engine will run at the preset speed regardless if the attachment is operated or not. The maximum engine speed for an attachment cannot be set higher than the fast idle speed of the machine.

NOTE: Selector valve control will not work properly unless appropriate kits are installed on machine. Valve Selector (selector valve)—The selector valve icon on the monitor controls the selector valve solenoid valve (Y40). The selector valve solenoid valve receives power from the optional and attachment 5 A fuse (F5) and is grounded by the main controller (MCZ) by pin C4. When the monitor displays “0”, the return oil from the attachment flows through the control valve before it returns to the hydraulic oil tank. When the monitor displays “1,” the return oil from the attachment flows directly to the hydraulic oil tank, bypassing the control valve. The selector valve solenoid valve can be adjusted for each attachment using MPDr, Service ADVISOR™, and the monitor. The valve selector will default to “0” or control valve in bucket mode (no attachment selected).

Accumulator—The accumulator controls the accumulator solenoid valve (Y42). The accumulator solenoid valve is powered by the optional and attachment 5 A fuse (F5) and grounded by the main controller (MCZ) by pin C17. When the accumulator is ON, the accumulator solenoid valve is activated, pilot oil is sent to the accumulator control valve. The accumulator shutoff valve shifts, connecting the accumulators to the supply and return lines of the attachment hydraulic circuit. The accumulators help reduce the shock of oil pressure and buffers vibrations when certain types of attachments are used, such as breakers. When the accumulator is OFF, the accumulator solenoid valve is deactivated and the accumulators are isolated from the attachment hydraulic oil circuit. The accumulator status for each attachment can be adjusted using MPDr, Service ADVISOR™, and the monitor.

NOTE: The 2-speed control will not work properly unless appropriate kits are installed on machine.

When 2-speed is activated, the flow rate adjustment solenoid valve can also be activated. When an arm out, boom up, swing, or travel function is actuated in combination with the attachment function, the flow rate adjustment solenoid valve is activated. When the flow rate adjustment solenoid valve is activated, pilot oil is routed to the auxiliary flow rate control valve, adjusting the auxiliary flow rate control valve to provide more or less priority to the arm out, boom up, swing and travel functions over the attachment function. The main controller (MCZ) can vary the signal to the flow rate adjustment solenoid valve to vary the pilot oil pressure at the auxiliary flow rate control valve, allowing for adjustment of the priority of the attachment function over arm out, boom up, swing, and travel. The 2-speed selector status can be adjusted for each attachment using MPDr, Service ADVISOR™, and the monitor. Adjustments to the priority level can be made in the monitor in the attachment adjustment menu. See Service Menu. (Group 9015-16.)

2-Speed Selector and Auxiliary Flow Combiner Valve—The 2-speed selector icon on the monitor controls the 2-speed activation solenoid valve (Y43) and the flow rate adjustment solenoid valve (Y44). The 2-speed activation solenoid valve is powered by optional and attachment 5 A fuse (F5) and grounded by the main controller (MCZ) pin C3. The flow rate adjustment solenoid valve is powered by MCZ pin B11 and grounded by pin B12. When activated, the 2-speed activation solenoid valve sends pilot oil to the bypass shutoff valve blocking hydraulic oil from pump 1 from returning to the hydraulic oil tank. The activated 2-speed activation solenoid valve also sends pilot oil to the auxiliary flow combiner valve to combine oil flow from pump 1 with that of pump 2, allowing for combined oil flow from pump 1 and pump 2 to operate the attachment.

Secondary Hydraulic Relief Selector—The secondary hydraulic relief selector icon in the monitor controls the secondary relief solenoid valve (Y41). The secondary relief solenoid valve receives power from the optional and attachment 5 A fuse (F5) and is grounded by the main controller (MCZ) pin C16. When the secondary relief solenoid valve is activated, pilot oil shifts the secondary relief shutoff valve, routing hydraulic oil from the high-pressure lines of the attachment to the secondary relief valve. The relief pressure of the circuit will then be equal to the lowest setting of the two relief valves in the circuit. The secondary hydraulic relief selector status can be adjusted for each attachment using MPDr, Service ADVISOR™, and the monitor. The secondary relief solenoid valve diode (V41) suppresses voltage spikes created when the solenoid valve is energized and de-energized.

Service ADVISOR™ Diagnostic Application The Service ADVISOR™ application is what technicians use to diagnose and troubleshoot equipment. The application allows technicians to quickly and easily find information and solve equipment problems. The Service ADVISOR™ application provides access to manuals, the Dealer Technical Assistance Center (DTAC), real-time diagnostics, and system readings. The application also allows technicians to perform calibrations, run tests, and program controllers, when possible. The Connection-Readings shortcut bar within Service ADVISOR™ is used to connect to a machine. A connection allows a technician to take live system readings, create recordings, diagnose problems, calibrate, interactively test, and program controllers. With a connection established, the Readings menu allows a

technician to add or remove a reading, set a readings baseline, and create and check recording triggers. With Service ADVISOR™ connected to a machine, the Diagnostics shortcut bar can be used to read machine diagnostic trouble codes. The diagnostic codes can then be reviewed by code number for specific details. When a diagnostic trouble code is opened, code information displays in a window similar to the way a manual would. The details of a diagnostic trouble code often are in a procedural format with links so the technician can work to correct the problem with the equipment while following the step-by-step process in the diagnostic trouble code details. See Service ADVISOR™ Connection Procedure. (Group 9015-20.) See Reading Diagnostic Trouble Codes with Service ADVISOR™ Diagnostic Application. (Group 9015-20.)

8— Recoil Spring 9— Grease 10— Track Adjuster and Recoil Spring

The track adjuster and recoil spring (10) is supported by the track frame. Shock loads on the track and front idler (6) are absorbed by the recoil spring (8). To decrease track sag, grease (9) is pumped into the cylinder (4) through the grease fitting (1). The grease pushes the piston (7) against the yoke moving the front

idler (6) out, reducing track sag. The grease fitting (1) is protected from excess pressure by a check ball. Increasing track sag is accomplished by loosening the valve (2) to release grease from the cylinder through the grease relief passage (3). When releasing grease from the cylinder, only loosen the valve (2). JW00603,0000239 -19-10NOV10-1/1

Theory of Operation

The travel motor driveshaft is connected to the first stage sun gear (input shaft) (12) by a spline coupler. Travel motion is transferred from the first stage sun gear to the sprocket (18) by the three planetary gear sets that mesh with the ring gear (6). As the first stage sun gear is rotated, it rotates the first stage planetary gears (14), causing the first stage carrier (11) to rotate. The first stage carrier is connected to the second stage sun gear (10). The second stage sun gear meshes with the second stage planetary gears (15). Second stage

planetary gears are connected to the second stage carrier (9). The second stage carrier is connected to the third stage sun gear (8). The third stage sun gear rotate the third stage planetary gears (16). The third stage planetary gears are fastened to the gear case housing and do not rotate. The rotation is transferred to the ring gear. The ring gear, drum (17) and sprocket are fastened together and turn as one unit which rotates the track to move the machine. A replaceable thrust pad (13) is used in the gear case cover to keep the first stage sun gear in position. MM16284,0001652 -19-24FEB12-2/2

Group 05

Theory of Operation Hydraulic System Operation See Hydraulic System Schematic as a reference for hydraulic system operation. (Group 9025-15.) Main hydraulic system is an open-center hydraulic system. Main pump housing contains a pilot pump (28), pump 1 (15), and pump 2 (16). Pump 1 is on the right side as you are looking at the pump compartment (toward front of machine), pump 2 is on the left side (toward rear of machine) and the pilot pump is mounted adjacent to pump 2 (toward the rear of machine). The engine drives the pumps through a coupler and a gear case. Hydraulic oil flows from hydraulic oil tank (31) through suction screen (35) to pump 1 and pump 2. Pump 1 delivers high pressure oil to right control valve (4-spool) (73), and pump 2 delivers high pressure oil to left control

valve (5-spool) (74). High pressure oil is routed to motor(s) (52, 61, and 63) and cylinder(s) (125, 126, and 127) by valve spool(s) of their respective valve section (75—110). Hydraulic oil tank is pressurized to ensure oil flows from hydraulic oil tank, through suction line, and into pumps. Return oil from motor(s) and cylinder(s) is routed into return passages in control valve by valve spools. From return passages, return oil flows out of control valve, through hydraulic oil cooler (36), and then to hydraulic oil tank. Oil cooler bypass valve (124) opens to route return oil around oil cooler and directly to hydraulic oil tank when resistance to flow through oil cooler becomes high because oil is cold (high viscosity), there is surge of return oil, or oil cooler becomes plugged. Back pressure in the return passage provides makeup oil to swing motor. JA66566,000263D -19-03AUG12-1/1

160GLC Excavator 042318 PN=819


Theory of Operation

The fan drive pump is directly driven off the front gear train of the engine. Oil flow to the pump comes from the hydraulic oil tank (31). Return oil (604) from the fan drive motor is routed to the return filter (32) in the hydraulic oil tank. The proportional fan speed solenoid valve (Y5014) regulates oil flow and pressure buildup in the fan drive system. Engine control unit (ECU) reads fan speed from fan speed sensor (B53), located on fan drive motor. See Fan Harness (W57) Component Location. (Group 9015-10.) The more oil flow to fan drive motor, the greater the fan speed. How much oil flow is routed to fan drive motor, depends on current applied to proportional fan speed solenoid valve from ECU. The ECU uses five parameters to control the current sent to the integrated proportional fan speed solenoid valve. The engine coolant temperature sensor (B4), hydraulic oil temperature sensor (B40), intercooler outlet temperature sensor (B5205), fuel temperature sensor (B5), and ambient air temperature sensor (B22) send system temperatures to the ECU. Each temperature input calculates a desired fan speed, the maximum of the fan speeds is used as output to the fan speed control valve. When machine systems are cold, the ECU sends maximum current to the proportional fan speed solenoid valve. This shifts the solenoid valve, to allow most oil flow to be returned to the hydraulic oil tank and bypass the fan drive motor. The fan drive motor and cooling fan operate at a low speed. As the machine warms up during operation, the ECU decreases the current to the proportional fan speed solenoid valve. The decrease in current applied, causes the solenoid valve to shift and restrict oil flow through the proportional fan speed solenoid valve, increasing oil flow to the fan drive motor. As oil flow to the fan drive motor increases, cooling fan speed increases. When maximum cooling is required, the ECU supplies low current to the proportional fan speed solenoid valve. With the solenoid valve at a set minimum current, LOW

VOLTAGE fan speed current, the fan drive motor and cooling fan operate at the set maximum speed of LOW VOLTAGE maximum speed. This controlled fan speed is more economical and fuel efficient. During a fan system fault or unplugged proportional fan speed solenoid, the ECU supplies no current to the proportional fan speed solenoid valve. With the solenoid de-energized, the proportional fan speed solenoid valve is fully shifted to allow maximum oil flow to the fan drive motor. The fan drive motor and cooling fan operate at maximum speed. Reverse Fan Function—If Equipped The optional reversing function, reverses cooling fan to help clean machine cooling package of dirt and debris. The reversing function can be initiated manually by the operator, or automatically by the ECU. If set to reverse automatically, the ECU will reverse the fan at a preset interval. In order to reverse the fan manually, the engine must be running above 1180 rpm and the hydraulic oil temperature must be above 12°C (54°F). See Reversing Fan Switch—If Equipped. (Operator's Manual.) The integrated fan speed and reversing control valve is used with the optional reverse fan function. The control valve controls both fan speed and reversing fan direction. To start a reversing cycle, the ECU first increases current to the proportional fan speed solenoid valve in the fan speed and reversing control valve. The engine control unit briefly applies maximum current to stop the fan, while the reversing fan solenoid valve (Y5015) shifts to reverse oil flow. The ECU then removes current to the proportional fan speed solenoid valve, to operate the fan at maximum speed in reverse for a short period of time. The ECU continues to calculate the desired speed for the fan forward inputs. After the reverse cycle completes, the ECU will return to the maximum desired speed. Returning to normal operation, the ECU briefly applies maximum current to the proportional fan speed solenoid valve while the reversing fan solenoid resets to normal operation. DF89619,00B57C3 -19-19MAY14-3/3

Pilot System Operation See Hydraulic System Schematic as a reference for the hydraulic system operation. (Group 9025-15.) Pilot system is used to operate control circuits for pump 1 and pump 2 regulators (17 and 18), to shift the right and left control valve (73 and 74) spools, to release the swing park brake (56), and as a supply source for functions of the solenoid valve manifold (37).

The pilot pump (28) supplies oil to the pilot system. From the pilot pump, oil flows to the pilot pressure regulating valve (30), which houses the pilot oil filter and pilot oil bypass valve (29). After leaving the filter, oil is supplied to the pilot shutoff valve, the pump regulators, and the solenoid manifold. When no functions are activated, the oil returns to hydraulic oil tank (31).

Pilot filter element (13), bypass valve, and pilot pressure regulating valve (30) are incorporated into one assembly. Pilot filter bypass valve senses differential pressure between inlet side and outlet side of filter element. During normal operation, bypass valve is held closed by a spring and pilot oil flows through filter element to pilot pressure regulating valve and out to pilot circuit. When the filter element becomes plugged, pressure on inlet side increases forcing bypass valve open. Pilot oil now bypasses the filter element and unfiltered oil flows to pilot pressure regulating valve spool (14) and out to the pilot circuit.

in pilot oil circuit. When pressure in pilot circuit increases to pressure setting of spring (15), spool is pushed against spring. Regulated pilot oil flows from port PD to solenoid valve manifold (10) and from port PC to pump 1 and 2 servo pistons and regulators (5). Oil not needed to maintain pressure in pilot circuit flows out port TA to hydraulic return manifold (6). See Hydraulic System Schematic for pilot filter, bypass valve, and pilot pressure regulating valve in Pilot Control Valves and Pilot Signal Manifold Schematic (Group 9025-15.)

Theory of Operation

With the pilot control shutoff lever in the locked position, the lever is up. The solenoid for the pilot shutoff solenoid valve is de-energized. Pilot oil from the pilot pump (P) is blocked by the spool. Ports to the pilot control valves (A1—A3) and pilot signal manifold port PI are open to the hydraulic oil tank (T4) through the spool. Therefore, no hydraulic function is actuated when a control lever for a pilot control valve is operated.

Theory of Operation

With the pilot control shutoff lever in the unlocked position, the lever is down. The solenoid for the pilot shutoff solenoid valve is energized. Ports to the pilot control valves (A1—A3) and pilot signal manifold port PI (A4) are now open to pilot oil from pilot pump (P). Now, operating a control lever actuates a function.

The left and right pilot control valves regulate the pilot oil (609) pressure to actuate the pilot valves in the pilot signal manifold and to shift the control valve spools to actuate each function. See Pilot Signal Manifold Operation for pilot valve operation. (Group 9025-05.) See Pilot Operation of Control Valve Operation for control valve operation. (Group 9025-05.) Each pilot control valve contains four valves, one for each function. The ports (10, 11, and 12) in housing (9) are identified by numbers and letters next to each port. The valves are pressure-reducing valves controlled by movement of the control lever (1) and plunger (2). Moving the control lever to actuate a function pushes the plunger and spring guide (3) against the balance spring (4) pushing the spool (7) down. The return spring (5) is also compressed by the plunger and spring guide.

During the initial movement (14), the spool goes through a deadband area (13) where the flow of return oil (604) through the holes (8) to port T is blocked before pilot oil flows from port P through the holes down through the spool to the work port and out to the control valve pilot caps (10). Pilot oil also flows through the orifice (6) to the top of spool to dampen the upward movement of spool. Pilot oil pressure out the work port increases until the pressure is equal to the force of balance spring pushing the spool up until the oil flow through the holes is blocked in the deadband area. With the oil flow blocked, the control valve spool is held stationary until the control lever is again actuated. When the control lever is actuated to full stroke, the plunger contacts the spool, pushing it down until the plunger contacts a shoulder in the housing. Oil pressure to the control valve pilot caps is now approximately equal to pilot system pressure.

The travel pilot control valve regulates the pilot oil (609) pressure to actuate the pilot valves in the pilot signal manifold and to shift the control valve spools to actuate the travel functions. See Pilot Signal Manifold Operation for pilot valve operation. (Group 9025-05.) See Pilot Operation of Control Valve Operation for control valve operation. (Group 9025-05.) One pilot control valve is used to control the travel functions. The pilot control valve contains four valve assemblies, one for each direction of travel for each track. The valves are pressure-reducing valves controlled by movement of the cams and pedals (6), against the plunger (4). The ports (10, 11, and 12) in housing are identified by numbers and letters next to each port. In neutral, the spool is pushed up by the return spring (9) pushing the plunger up. The return springs hold the pedal in the neutral position. With the spool up, ports 1, 2, 3, and 4 to control valve pilot cap (12) are open to port T to the hydraulic oil tank (10) through the passage and holes in spool. Port P for pilot oil from the pilot shutoff solenoid valve (11) is blocked by the spool.

604— Return Oil 609— Pilot Oil

When the pedal is pushed to move the machine, the cam pushes the plunger and spring guide down against the return spring and balance spring. The balance spring pushes the spool down. As the spool is pushed down and the holes move through the deadband area, the passage from control valve pilot cap to the hydraulic oil tank is closed and then opened to the pilot oil from pilot shutoff solenoid valve. Pilot oil pressure increases until it is equal to the force applied by the balance spring pushing the spool up until the oil flow through the holes is blocked in the deadband area. With the oil flow blocked, the control valve spool is held stationary until the pedal is again actuated. When the pedal and cam is pushed to full stroke, the plunger is pushed down farther by the balance spring opening the passage through the spool to pilot oil pressure. When pressure to the control valve pilot cap is equal to the force applied by the balance spring, the spool moves up until it contacts the plunger. The plunger holds the spool down so the passage through the spool remains open to pilot oil pressure. Oil pressure to the control valve pilot cap now approximately equals pilot oil pressure.

JA66566,0002642 -19-03AUG12-2/3

The travel pedal is equipped with a shockless function. The shockless function consists of a bracket (18) connected to the travel pedal (14) and a support (17) connected to the bracket with a spring pin (15). Gear 1 (20) is connected to the support. When the travel pedal is released while traveling, the spring forces the travel pedal to the neutral position. At this time gear 1 and gear 2 (19) inside the damper (16) receive resistance due to friction. The travel pedal gradually returns to neutral preventing a sudden stop due to sudden release of the travel pedal.

The pilot control valves and travel pilot control valves are connected to the control valve by lines through the pilot signal manifold (41). Actuating a pilot control valve routes pilot oil (609) through the pilot signal manifold to the control valve pilot cap to shift a spool. Pilot oil also flows through the shuttle valves in the pilot signal manifold and shifts the pilot valves.

NOTE: The numbers 1—14 and letters A—N, DF, TR, S3, SA, SB, SE, SH, SK, SL, SM, SN, SP, PH, and PI are next to the respective ports on the pilot signal manifold. The pilot signal manifold is in the pilot system between the pilot control valves and the control valve and regulators. The manifold receives a pilot signal from the pilot control valves and sends the signal on multiple paths. One path

is used to shift the spools in the control valve and the other sends a signal to the regulators through pump 2 flow rate pilot valve (47) and pump 1 flow rate pilot valve (48). This is done simultaneously so there is little lag between operation of the pilot control valves, pump stroke, and function movement. The manifold also houses additional pilot valves that provide pilot oil for various other functions. See Hydraulic System Schematic. (Group 9025-15.)

Boom Down Shockless Valve The boom down shockless valve (42) regulates the return oil flow from the pilot cap during boom down operation. Regulating the return oil flow controls the movement of boom 1 and boom 2 spools to provide precise control of boom down function. Actuating boom up sends pilot oil to pilot signal manifold port A. Pilot oil flows past the tapered land (140) on the boom down shockless valve spool and into the oil chamber (144). The tapered land acts as a variable orifice between the spool and manifold as the spool is shifted back and forth. Pilot oil flows from the oil chamber, through the orifice (141), into passage 2 (145), and out port 1 to the control valve pilot cap. Pilot oil also flows through passage 3 (143) into spring B (142) cavity and passage 1 (139) into spring A (138) cavity. Because spring B is the larger spring, the increasing pilot oil pressure shifts the valve spool to the left, opening the passage from port A to port 1 and allowing pilot oil to flow unrestricted to the pilot cap shifting the boom 1 and boom 2 valve spools.

Actuating boom down sends return oil from the pilot cap to port 1. From port 1 pilot oil flows through passage 1 to spring A cavity and through passage 2, through the orifice, and into the oil chamber. From the oil chamber return oil flows through passage 3 to spring B cavity and past the tapered land to port A. Because of the pressure drop across the orifice, the return oil pressure in the oil chamber and spring B cavity is less than the return oil pressure in spring A cavity. The increasing return oil pressure shifts the valve spool to the right causing the tapped land to restrict and then block the flow of return oil from port 1 to port A. When the tapered land blocks the return oil flow, the pressure increases in the oil chamber and spring B cavity. The valve spool now shifts to the left allowing return oil to flow past the tapered land to port A. The opening and closing continues until the return oil is gradually returned through port A controlling the movement of the boom 1 and boom 2 spools.

The spool is shifted back to the left until the regulated pilot oil pressure equals the oil pressure in the spring chamber and spring force stopping the oil pressure increase to the pump regulator.

The function of pump 1 and pump 2 flow rate pilot valves is to deliver a regulated amount of pilot oil to the pump 1 and pump 2 regulators in proportion to the pilot oil pressure applied to the flow rate pilot valve spools (47 or 48) by the actuated pilot control valves (147). The pilot oil delivered by the flow rate pilot valves is from the pilot control shutoff valve port A4 to the pilot signal manifold through port PI (149). Pump 1 flow rate pilot valve delivers regulated pilot oil to pump 1 through port SA. Pump 2 flow rate pilot valve delivers regulated pilot oil to pump 2 through port SB. The pilot oil from the actuated pilot control valve is routed to the flow rate pilot valves by the shuttle valves. Actuating a function sends pilot oil from the pilot control valve to the pilot signal manifold. The pilot oil flows through the manifold to the control valve pilot cap and within the manifold to the spring chamber (150). The pilot oil pressure in the spring chamber increases, shifting the flow rate pilot valve spool to the right and allowing a regulated

NOTE: Ports SA and SB are located on the control valve side of pilot signal manifold (41A) but, for simplification of the schematic, are shown on the pilot control valve side of pilot signal manifold (41B). When the function is returned to neutral, oil pressure in the spring chamber is released to the hydraulic oil tank through the pilot control valve. The regulated pilot pressure on the right end of spool shifts the spool to the left against the spring, releasing the regulated pilot oil pressure to the hydraulic oil tank by port DF (146). As the regulated pilot oil pressure decreases, the spool is shifted back to the right by the spring until the spring force and oil pressure are equal.

Pump 1 (15), pump 2 (16) and pilot pump (28) are driven by the engine at engine speed through the drive gear (24) in pump drive gear case (2). The pump 2 drive shaft is connected to the engine flywheel through a damper drive (flex coupling). Pump 1 and pump 2 are variable displacement, bent-axis, piston type pumps. Two identical pumps are used to generate high pressure oil flow in the hydraulic system. The pumps can vary from minimum displacement to maximum displacement depending on hydraulic demand of the system. Pump 1 regulator (17) and pump 2 regulator (18) are attached to the top of pump housing. The regulators control the movement of the servo piston (19) by sending or releasing oil from the large end of the piston. The servo piston moves the valve plate (22) and cylinder block (21) changing the pump displacement. The feedback link (26), connected to the valve plate, provides a mechanical

feedback to the remote control sleeve in the regulator. The remote control sleeve blocks the flow of oil and traps the oil at both ends of the servo piston, stopping its movement at the flow rate in proportion to the control lever actuation. See Pump 1 and Pump 2 Regulator Operation. (Group 9025-05.) The pump displacement, or flow rate, is varied by changing the angle of the cylinder block with respect to the drive shaft. Expanding the angle increases the distance that each piston travels into and out of the bore, which increases displacement. Decreasing the angle reduces the distance that each piston travels into and out of the bore, which decreases displacement. An attenuator hose is connected to pump 1 attenuator port and pump 2 attenuator port (10 and 11) to the machine frame. The attenuator hoses help reduce pump vibrations during operation.

Pump Regulator Component Identification—Function of pump 1 and pump 2 regulators is to control pump 1 and pump 2 flow rates (displacement) in response to various oil pressure signals so pump drive torque does not exceed engine torque.

Remote control sleeve (4) and load sleeve (12) are moved by feedback link blocking flow of oil to or from large end of servo piston.

Piston (6) controls remote control spool (5) movement against spring in response to flow rate valve pilot oil pressure from pump 1 and pump 2 flow rate pilot valves. Actuating control levers or pedals shifts flow rate pilot valves. See Pilot Signal Manifold Operation for pump 1 or pump 2 flow rate pilot valves operation. (Group 9025-05.) Load piston (14) controls load spool (13) movement against inner and outer springs (10 and 11) in response to pilot oil pressure from torque control solenoid valve and supply oil pressure from pump 1 and pump 2. Supply oil pressure from pump 1 is sensed on one shoulder of load piston and from pump 2 on other shoulder. Pilot oil pressure increases or decreases in response to actual engine speed to target engine speed difference or when a travel function is actuated at slow engine speed. See Engine Speed Sensing Control Circuit Operation. (Group 9025-05.))

Pump 1 and pump 2 regulators are mounted on top of pump housing. Torque control solenoid valve and pump 2 flow rate limit solenoid valve are located in housing on top of pump 2 regulator. See the following tests and adjustments for minimum flow adjusting screw (7):

Pump Regulator Control by Flow Rate Pilot Valve—Pilot oil (609) from pilot pump is constantly supplied through drilled passages in pump housing to small end of servo pistons, to pilot oil inlet (19) at each pump regulator, and to torque control solenoid valve located on top of pump 2 regulator. Pump flow rate (displacement) is changed by sending pilot oil to or releasing oil from large end of servo piston (15). Flow rate valve pilot oil (613) from pump 1 and pump 2 flow rate pilot valves (SA or SB) in pilot signal manifold is sensed by piston (6) in its respective regulator. Supply oil (600) from pump 1 and pump 2 is sensed through drilled passages in pump housing to pump 1 pressure inlet (20) and pump 2 pressure inlet (21) in each pump regulator.

Increasing Flow Rate (Displacement)—Actuating a function increases flow rate valve pilot oil (613) pressure from pump 1 or pump 2 flow rate pilot valve (SA or SB) (16) to piston (6). Oil pressure pushes piston and remote control spool (5) to left against spring. Movement of spool opens path from large end of servo piston (15) to return in pump housing (23). Pilot oil on small end of servo piston pushes piston down, increasing pump angle which increases flow rate (displacement). Servo piston movement is transmitted to remote control sleeve (14) and load sleeve (12) by feedback link (18). Sleeves move left until path to return is closed. Oil at large end of servo piston is now trapped, holding pump at flow rate (displacement) that is proportional to pressure of flow rate valve pilot oil.

Torque sensing pilot oil (611) from torque control solenoid valve is routed through steel lines to torque sensing port (22) in each pump regulator.

Theory of Operation

Maximum Flow Rate (Displacement)—When controller lever or pedal is actuated to full stroke, flow rate valve pilot oil (613) from pump 1 or pump 2 flow rate pilot valve (SA or SB) (16) to piston (6) increases to its maximum pressure. Oil pressure pushes piston and remote control spool to left until spool contacts maximum flow adjusting screw. Movement of spool opens path from large end of servo piston to return in pump housing (23). Pilot oil on small end of servo piston pushes piston down, increasing pump flow rate (displacement). As flow rate (displacement) increases, servo piston movement is transmitted to remote control sleeve (4) and load sleeve (12) by feedback link (18). Sleeves move left until path to return is closed. Oil at large end of servo piston is now trapped, holding pump at maximum flow rate (displacement).

oil (613) pressure sensed at piston (6) also decreases. Spring pushes remote control spool and piston to right. Movement of spool opens path for pilot oil (609) from pilot oil inlet (19) to flow to large end of servo piston (17). Pilot oil pressure applied to large end of servo piston pushes piston up against pilot oil pressure applied to small end decreasing pump flow. Remote control spool continues to move to right in response to decreasing flow rate valve pilot oil pressure until it contacts piston cylinder. As pump flow rate (displacement) decreases, servo piston movement is transmitted to remote control sleeve (4) and load sleeve (12) by feedback link (18). Sleeves move right until path for pilot oil is closed.

Pump Regulator Control by Supply Oil Pressure—Supply oil (600) pressure (load) for each pump is sensed on shoulders of load piston (14) through pump 1 and pump 2 pressure inlets (20 and 21) in each pump regulator. Area of each shoulder is equal. Therefore, force applied through load spool (13) to inner and outer springs is an average of supply oil pressures. Springs are adjusted against average pressure so flow rate of each pump is approximately equal and uses approximately one-half engine output.

feedback link moves load sleeve and remote control sleeve (4) blocking flow of oil. Flow rate of both pumps decreases so load on pumps does not exceed engine output. For decreasing supply oil, pressure (load) springs push load spool and pistons to right against supply oil pressure, opening path for oil to flow from large end of servo piston (15) through load sleeve and remote control sleeve to return in pump housing (23). Flow rate increases until feedback link moves load sleeve and remote control sleeve blocking flow of oil.

Increasing supply oil pressure (load) pushes load pistons and spools against springs, opening path for pilot oil (609) to flow from pilot oil inlet (19), through load sleeve (12) to large end of servo pistons (15). Flow rate decreases until

Engine output is not exceeded, even if one pump is loaded relatively high while other pump stays relatively low.

Pump Regulator Control by Speed Sensing Pilot Oil—As engine speed changes, the main controller calculates speed difference between target and actual engine speed. Main controller then actuates torque control solenoid valve to increase or decrease torque sensing pilot oil (611) pressure to torque sensing port (22) and load piston (14).

sensing pilot oil pressure, releasing oil from large end of servo piston to return in pump housing (23) allowing pump displacement to increase. As pump flow rate increases engine output is used more efficiently.

As load on engine increases, speed difference between target and actual engine speed increases. Main controller decreases voltage to torque control solenoid valve, which increases torque sensing pilot oil pressure to load piston. Torque sensing pilot oil along with supply oil pressure shifts load spool so pilot oil (609) flows to large end of servo piston (15), decreasing flow rate (displacement). As flow rate of both pumps decreases, load on engine also decreases allowing actual engine speed to increase. As load on engine decreases, speed difference between target and actual engine speed decreases. Main controller increases voltage to torque control solenoid valve, which decreases torque sensing pilot oil pressure to load piston. Spring shifts load spool in response to decreasing torque

Also, actuating travel function at slow engine speed causes pump flow rate to increase. Flow rate is increased to prevent mistracking, which may occur at lower flow rate if there are any differences between pump 1 and pump 2 flow rates. Main controller processes voltage signals from engine speed dial, travel pressure sensor, and pump 1 and pump 2 pressure sensors. Main controller sends an increasing voltage to torque control solenoid valve, which decreases torque sensing pilot oil pressure to load piston. Springs shift load spool in response to decreasing torque sensing pilot oil pressure, releasing oil from large end of servo piston allowing pump flow rate (displacement) to increase. At increased flow rate, machine does not mistrack at slow engine speed. Increased flow rate continues even if dig function is actuated while traveling at slow engine speed.

Theory of Operation

The engine control unit (ECU) (A1) receives signals from crankshaft position sensor (B5301) and camshaft position sensor (B5302), calculates engine speed, and sends information to the main controller (MCZ) (A3) using CAN communication.

in response to the decreasing pilot oil pressure, releasing oil from the large end of servo piston thus increasing pump displacement. As pump flow rate increases, engine output is used more efficiently. See Pump 1 and Pump 2 Regulator Operation. (Group 9025-05.)

The MCZ calculates the speed difference between target and actual engine speed. Target engine speed is a value set by the position of engine speed dial (R15). Actual engine speed is calculated by the ECU using crankshaft position sensor and camshaft position sensor inputs. The MCZ then actuates the torque control solenoid (Y21) to change the pump displacement to increase or decrease pump flow rate.

Travel Torque-Up Control (Slow Speed Sensing)—The function of travel torque-up control is to increase pump flow rate when travel functions are actuated at slow engine speed.

As a load on the engine increases, the actual engine speed becomes less than the target engine speed. The MCZ decreases the electrical signal to the torque control solenoid valve, which increases the pilot oil (609) pressure to load piston 1 in the pump 1 regulator (17) and pump 2 regulator (18). Pilot oil pressure on load piston 1 and high-pressure oil (600) on load piston 2 shifts load spool (6), allowing pilot oil flow to the large end of servo piston thus decreasing the pump displacement. As pump flow rate is reduced, the load on the engine is reduced. As the load on the engine decreases, actual engine speed becomes greater than target engine speed. The MCZ increases the electrical signal to the torque control solenoid, which decreases pilot oil pressure to the load piston in the regulators. The spring (1) shifts the load spool

Actuating travel functions with engine at slow idle causes the pumps to go to maximum displacement. Pump 1 and 2 flow rates are increased to prevent mistracking. Mistracking can occur at lower flow rates if there are differences between pumps 1 and 2. When the engine speed requested by the engine speed dial is slow, the MCZ processes the electrical signals from the travel pressure sensor (B34), pump 1 delivery pressure sensor (B35), and pump 2 delivery pressure sensor (B37). The MCZ sends an increasing electrical signal to the torque control solenoid, which decreases pilot oil pressure to load piston 1 in the regulators. The springs shift the load spool in response to the decreasing pilot oil pressure, releasing oil from the large end of servo piston and allowing pump displacement to increase. See Pump 1 and Pump 2 Regulator Operation. (Group 9025-05.) The increased flow rate continues even if a dig function is actuated while traveling at slow engine speed. DF89619,00B5722 -19-02APR14-2/2

The control valve consists of two monoblock valves referred to as the left control valve (5-spool) (74) and right control valve (4-spool) (73). The 4-spool and 5-spool valves are mounted back-to-back so the oil passages in the valves are connected. The spools are selectively fitted. There is a spool in each valve to control the boom (81 and 104), arm (90 and 97), and travel (75 and 110) functions. All other functions are supplied by a single spool in one or the other of the valves. All spools are moved by pilot oil. Check valves are used as lift checks and to route supply oil between the 4-spool and 5-spool valves for combined operation. The control valve is an

open-center type valve. Each valve section controls the flow rate and direction for its hydraulic circuit. See Hydraulic System Schematic for more information. (Group 9025-15.) All valves are accessible from the outside of control valve by removing a plug, cover, or the pilot caps. See Control Valve Line Identification. (Group 9025-15.) See Control Valve Check Valves Identification and Operation for check valves. (Group 9025-05.)

Supply oil from pump 1 (15) flows to the right control valve (73). Supply oil from pump 2 (16) flows to the left control valve (74). When all functions are in neutral, supply oil flows through the neutral and power passages for each valve spool section and then into the return passage. Neutral and power passages in the left and right control valves are used to route supply oil for the combined operation of functions. Combiner oil (610) is connected in

combiner passages between arm 1 and 2 spools (97 and 90), and boom 1 and 2 spools (81 and 104), so supply oil from both pump 1 and pump 2 flows to the cylinders during a single operation. Supply oil from pump 2 can be combined with supply oil from pump 1 by the auxiliary combiner power passage to supply the auxiliary spool (107).

For location of check valves and orifices in the right and left control valves (73 and 74), see Control Valve Operation. (Group 9025-05.) Check Valves (92, 96, and 111): Check valves function as lift checks in the neutral passages.

Operational Check: Arm in function is slow or lacks power when dig. Inspect check valve for leakage. Also inspect the orifice (notch) in arm 1 spool and the orifice in the arm regenerative valve for restriction.

Check Valves (105 and 112): Check valves function as lift checks in the power passages. Check Valve (lift check)—Dig Regenerative Circuit (100): Functions as a lift check for arm in function when dig regenerative solenoid valve is actuated. See Dig Regenerative Valve Circuit Operation for solenoid valve operation. (Group 9025-05.) See Control Valve Operation for location and operation of dig regenerative valve. (Group 9025-05.)

Check Valve (lift check)—Arm 1 Regenerative Circuit (99): During arm in regenerative operation when the arm regenerative valve (94) is closed, check valve (99) is pushed open when return oil from the rod end of arm cylinder becomes greater than high pressure oil from pump 2 (16). Return oil combines with the high pressure oil flow to the head end of arm cylinder preventing cavitation. When high pressure oil pressure to the head end of arm cylinder is higher, all return oil from rod end flows to the return passage through the orifice (notch) in the arm 1 spool (97) and orifice in the arm regenerative valve. Return oil from the rod end only flows through the

Main Relief Valve Isolation Check Valve—5-Spool (115): One main relief and power dig valve (117) is used to limit the high pressure oil pressure. The higher pressure closes the check valve against the lower pressure so it cannot flow to the lower pressure side of control valve. The higher pressure is sensed by the main relief and power dig valve. Operational Check: Pump 2 (16) high pressure oil pressure becomes hard to increase. To check, operate bucket dump function over relief and check pressure at pump 1. If pressure is less than main relief and power dig valve pressure setting, inspect isolation check valve (115). Also, power and neutral passage oil flow pressure for the 5-spool side is high because oil is flowing past the isolation check valve (115). Main Relief Valve Isolation Check Valve—4-Spool (116): Operational Check: Pump 1 (15) high pressure oil becomes hard to increase. Operate swing function at stall and check pressure at pump 2. If pressure is less than swing crossover relief valve pressure setting, inspect the isolation check valve (116). Also, neutral passage oil flow pressure for the 4-spool side is high because oil is flowing past the isolation check valve (116).

Theory of Operation

Check Valve—Auxiliary Function Flow Combiner Valve Circuit (119): For pump 1 (15) and pump 2 (16) combined flow to the auxiliary spool (107), a pilot line from the auxiliary spool pilot cap must be connected to shift the auxiliary function flow combiner valve (118) and bypass shutoff valve (93). Check valve closes if high pressure oil in the left control valve (74) power passage becomes higher than high pressure oil pressure in the right control valve (73) neutral passage. Check Valve—Travel Flow Combiner Valve Circuit (121): Blocks a higher high pressure oil pressure in the left control valve (5-spool) (74) from flowing to the right control valve (4-spool) (73) in travel flow combiner circuit. Operational Check: Machine mistracks to the left, forward or reverse, when traveling and operating a dig function. To check, operate a dig function over relief while traveling. If mistracking stops, inspect check valve (121). Circuit Relief and Anticavitation Valves (79, 80, 88, 89, 102, and 103): The anticavitation valves open when return oil pressure becomes greater than high pressure oil pressure to provide makeup oil to prevent cavitation in the cylinder.

High pressure oil flow from pump 1 to the bucket spool is blocked by the right travel spool (75) when actuated. High pressure oil flow from pump 1 to the bucket spool is now through the travel flow combiner valve (120), check valve (121), check valve (122), and orifice (123). The orifice restricts the flow of pump 1 high pressure oil to the bucket spool. Operational Check: Actuate left and right travel and bucket functions. If bucket does not move, inspect check valve and orifice. Check Valve—Dig Regenerative Circuit (106): Not used in this configuration. Hydraulic Oil Cooler Bypass Valve (124): Opens to route return oil around hydraulic oil cooler and directly to hydraulic oil tank when resistance to flow through oil cooler becomes high because the oil is cold (high viscosity), there is a surge of return oil, or oil cooler becomes plugged. The pressure setting for the bypass valve is higher than the restriction valve. Operational Check: Hydraulic oil continues to run hot. Check for an open bypass valve.

Check Valve (lift check) (122) and Orifice (123): The check valve functions as a lift check for the bucket spool (76). JA66566,0002649 -19-03AUG12-3/3

to the bottom of its bore, increasing the pressure setting of pilot poppet spring (7). The main hydraulic system now operates at a higher operating pressure for approximately 8 seconds.

Main Relief and Power Dig Valve (117)—The function of the main relief and power dig valve is to limit the main hydraulic system operating pressure. Main relief and power dig valve is pilot operated, poppet type relief valve with a piston (5). When the high-pressure oil (600) in the power passage (12) exceeds the relief valve pressure setting, pilot poppet (8) is pushed off its seat letting oil behind main poppet (10) flow to the return passage (11). A pressure difference is created across main poppet because oil flows out faster than oil can flow through orifice in the poppet. The main poppet is pushed open to relieve pressure oil to return passage.

Main relief valve isolation check valves are used in the left and right control valve to route the higher high-pressure oil to the main relief and power dig valve. The higher pressure closes an isolation check valve against the lower pressure so it cannot flow to the lower pressure side. The higher pressure is then sensed by the main relief and power dig valve. For main relief valve isolation check valves, see Control Valve Check Valves Identification and Operation (Group 9025-05.)

For power dig operation (14), pilot oil (609) from the power dig/travel speed solenoid pushes the piston down Continued on next page

When the power dig switch (S7) is pushed and held, the main controller (MCZ) (A3) sends electrical voltage (650) to energize the power dig/travel speed solenoid (Y24) coil. Pilot oil (609) flows from the valve to the piston in main relief and power dig valve (117). The pilot oil pressure pushes the piston in the main relief valve and power dig

The power dig control circuit stays actuated for approximately 8 seconds as long as the switch is held closed. After 8 seconds, the switch must be released and pushed again to actuate the power dig control circuit. A timer circuit in the MCZ controls the length of time control circuit is actuated. Releasing the switch before 8 seconds causes the power dig control circuit to turn off.

Auto-Power Dig Control Circuit—The function of the auto-power dig control circuit is to increase the system operating pressure during boom up operation. Control circuit is also activated during combined operations except when the arm in function is used. During boom up operation, the main controller (MCZ) (A3) actuates the power dig/travel speed solenoid (Y24) under the following conditions:

• Pilot control valve is actuated, sending pilot oil to the

pilot cap, shifting boom 1 and 2 spools to some extent. Also pressurizes the boom up pressure sensor (B30), sending an electrical signal to the main controller. • Pump 1 (15) delivery pressure is high. Pump 1 delivery pressure sensor (B35) sends an electrical signal to the MCZ indicating the high pressure.

• Control lever for arm in is in neutral. Electrical signal for arm in pressure sensor (B31) is at zero.

When all conditions are met, the MCZ sends an electrical signal to energize the power dig/travel speed solenoid coil, allowing pilot oil (609) to flow to the piston in main relief and power dig valve (117). The pilot oil pressure shifts the piston in the main relief and power dig valve against spring pressure to increase the pressure setting. The main hydraulic system now operates at the higher operating pressure.

Power Dig/Travel Speed Solenoid Operation—The power dig/travel speed solenoid (Y24) is a proportional solenoid valve type. The solenoid valve is activated by an electrical signal from the main controller (MCZ). The electrical signal is DC voltage that is turned on and off to form a pulse-width, modulated signal. Solenoid coil (24) reacts to the average voltage to create a magnetic force to shift the spool (22) left against a spring. When shifted left, reduced pilot oil (613) is sent to the main relief and power dig valve (20). The pressure of reduced pilot oil is in proportion to the electrical signal to the solenoid coil. When de-energized, the spool is pushed to the right by a spring. The main relief and power dig valve is then connected to the hydraulic oil tank (21) through the spool.

604— Return Oil Y24— Power Dig/Travel Speed 609— Pilot Oil Solenoid (marked SG) 613— Reduced Pilot Oil Y22— Dig Regenerative Solenoid (marked SF) Y23— Arm Regenerative Solenoid (marked SC)

When energized, the magnetic force shifts the spool left against the spring. Pilot oil (609) flows past the spool flange and out the port as a reduced pilot oil to the main relief and power dig valve. Because the flange on the right is larger than the flange on the left, the spool is pushed to the right against the magnetic force as the electrical signal to the solenoid increases. When the reduced pilot oil pressure equals or greater than magnetic force (23), the spool is pushed to the right closing the passage. The reduced pilot oil to the main relief and power dig valve is trapped. The spool is moving constantly to maintain the reduced pilot oil pressure in response to the electrical signal to the solenoid coil. DF89619,00B58AD -19-19JAN16-4/4

At pressures below the circuit relief setting, the main poppet (10) remains closed. In relief operation (11), the relief valve opens in three steps. In the first step, the pilot poppet (5) is opened. Flow restriction through the hollow piston (2) causes the pressure in the cavity behind the main poppet to decrease. In the second step of relief operation, the piston seats against the pilot poppet. This further reduces oil flow into the cavity and greatly decreases the pressure against the back side of main poppet. The main poppet opens in the third step of relief operation.

604— Return Oil 624— Low Pressure (cavitation)

During anticavitation operation (12), the check valve (4) retracts to allow oil to flow from the return passage into the work circuit. During normal operation, the operating pressure oil (602) on the inner shoulder holds the check valve against its seat. This pressure decreases as pressure in the work circuit decreases. The return oil (604) on the outer shoulder moves the check valve, main poppet, and piston against the springs to open the valve. MM16284,0000FD9 -19-25FEB11-1/1

When travel only is actuated, supply oil (600) from pump 2 (16) flows through the neutral passage of swing, arm 1, boom 2, and auxiliary spools, then through the left travel spool (110) and out to the left travel motor (63). Supply oil from pump 1 (15) flows through the right travel spool (75) and out to the right travel motor (61). Right travel spool blocks the flow of supply oil through the neutral passage of bucket (76), boom 1, and arm 2. When dig functions are actuated at the same time as travel, the travel flow combiner valve (120) is shifted by pilot oil (609) from the travel flow combiner pilot valve (port SL) in the pilot signal manifold. See Pilot Signal Manifold Operation for operation of pilot valves. (Group 9025-05.)

Supply oil from pump 1 flows to right travel spool and now through the travel flow combiner valve to the left travel spool and bucket spool. Supply oil flow from pump 1 to both left and right travel motors prevents mistracking. When travel is not actuated, return oil and spring force keeps the travel flow combiner valve closed. Supply oil from pump 2 (16) is used for the swing, arm, and boom functions and when connected, the auxiliary function.

Actuating an auxiliary function, with 2-speed activation solenoid valve (Y43) energized, routes pilot oil (609) from flow rate select solenoid valve (156) to the auxiliary flow combiner valve, shifting the spool. The auxiliary flow combiner valve works in conjunction with the bypass shutoff valve. When the bypass shutoff valve is shifted, pump 1 high-pressure oil in neutral passage flow to return passage is blocked. High-pressure oil now flows through the auxiliary flow combiner valve and combines with pump 2 oil at the auxiliary spool (107). Check valve—flow combiner valve circuit (119) prevents back flow of oil through the auxiliary flow combiner valve.

Theory of Operation

During boom down (2) operation the boom lower meter-in cut valve is shifted by regenerative oil (603) from the boom cylinders. See Boom Regenerative Valve Circuit Operation. (Group 9025-05.) The boom lower meter-in cut valve blocks control pilot oil to the boom 2 spool and directs it to the switch valve in the boom flow rate control valve. The poppet of boom flow rate control valve now restricts supply oil (600) flow from pump 1 to the boom 1 spool. See Boom Flow Rate Control Valve Circuit Operation. (Group 9025-05.)

Supply oil is restricted to the boom 1 spool. Regenerative oil from the boom cylinder head end is routed through the boom regenerative valve (82) to the boom cylinder rod end. Supply oil flows unrestricted to the other circuits that pump 1 supplies. When boom cylinder return oil pressure drops, the boom lower meter-in cut valve shifts. The switch valve in the boom flow rate control valve opens and allows supply oil from pump 1 to flow to the boom 1 spool. Boom down control pilot oil can now shift the boom 2 spool.

During operation of boom down and other function, the boom lowers due to own weight. MM16284,0000FDA -19-10FEB11-2/3

During boom down operation, control pilot oil (609) flows to the boom 2 spool through boom lower meter-in cut valve. Regenerative oil from the boom cylinders flows to the spring chamber (5) in boom lower meter-in cut valve through the orifice (4).

When pressure in the spring chamber becomes larger than the spring force, the boom lower meter-in cut valve is shifted.

Control pilot oil flows to and shifts the switch valve in the boom flow rate control valve. See Boom Flow Rate Control Valve Circuit Operation. (Group 9025-05.) During combined operation of boom lower and other functions, more supply oil is available to the other functions to ensure priority to them. 1— To Hydraulic Oil Tank 2— From Boom Down (pilot) 3— From Boom Cylinders 4— Orifice 5— Spring Chamber 6— From Boom 2 Spool

The boom regenerative valve (82) is located inside the boom 1 spool (81). The boom regenerative valve improves boom control and prevents boom cylinder cavitation during boom down operation.

When regenerative oil (610) pressure is more than pump 1 supply oil (600), the boom regenerative valve (82) is open. Regenerative oil is combined with pump 1 supply oil and both are supplied to the boom cylinders rod end. When pump 1 supply oil is more than regenerative oil pressure, the boom regenerative valve is closed. Pump 1 supply oil only flows to the boom cylinders rod end. Regenerative oil passes through an orifice (57) and back to hydraulic oil tank.

The boom regenerative valve operates under the following operating conditions: low pump 1 delivery pressure and pilot oil pressure to the pilot cap for boom down, the weight of boom, arm, and bucket causes the boom to lower faster than the pump can supply oil to the boom cylinder rod end. Pilot oil (609) shifts the boom 1 spool to the boom down position. The pilot oil also shifts the boom reduced leakage valve (85) to allow oil to flow from the head end of the boom cylinders.

The dig regenerative solenoid (marked SF) (Y22) is a proportional-type solenoid valve. The solenoid valve is actuated by a voltage signal from the main controller (MCZ). The voltage signal is a DC voltage that is turned on and off to form a pulse width modulated signal. The solenoid (1) reacts to the average voltage to create a magnetic force to shift the spool (2) left against a spring. The reduced pilot oil (613) pressure sent to the valve function (3) depends on how long the voltage signal is on versus how long it is off. The reduced pilot oil pressure is in proportion to the voltage signal. When de-energized (7), the spool is pushed to the right by a spring. The valve function port is connected to the hydraulic oil tank (31) port.

regulator valve (30) flows past the spool flange and out the valve function port as reduced pilot oil. Because the flange on the right is larger than the flange on the left, the spool is pushed to the right against the magnetic force as the oil pressure to the valve function increases. When the oil pressure becomes equal to or greater than the magnetic force, the spool is pushed to the right closing the passage stopping the pressure increase. The oil pressure to the valve function is trapped. The spool is moving constantly to maintain the oil pressure in response to the voltage signal to the solenoid coil. See Control Valve Operation. (Group 9025-05.) Also see Main Controller (MCZ) Circuit Theory of Operation. (Group 9015-15.)

When energized (6), the magnetic force shifts the spool left against the spring. Pilot oil (609) from the pilot pressure DF89619,00B5727 -19-08DEC15-5/5

The arm regenerative valve (94) improves arm control and prevents arm cylinder (127) cavitation during arm in operation by combining return oil from arm cylinder rod end with the pump supply oil to the arm cylinder. The main controller (MCZ) (A3) sends a voltage signal (650) to arm regenerative solenoid (Y23) to energize the coil under the following conditions:

• Low-pressure at pump 1 delivery pressure sensor (B35) or pump 2 delivery pressure sensor (B37)

• High-pressure (arm in fully actuated) at arm in pressure sensor (B31)

• Pressure at swing pressure sensor (B33) or boom up pressure sensor (B30)

The solenoid valve then routes pilot oil (609) to shift the arm regenerative valve and arm 2 flow rate control valve (91) switch valve. The return oil (604) route from arm cylinder (127) rod end to tank is blocked while arm regenerative valve is shifted, causing pressure to rise. Return oil pressure opens check valve (99) and is combined with supply oil from pump 2 (16). Regenerative oil (610) and supply oil flows through arm 1 spool (97) and is routed to arm cylinder head end increasing cylinder speed and preventing cavitation.

The bucket regenerative valve combines regenerative oil (610) from the bucket cylinder (126) rod end with pump 1 high pressure oil (600) to prevent cavitation and improve function control. The bucket regenerative valve functions under the following operating conditions: low pump 1 (15) delivery pressure and pilot oil (609) pressure to the pilot cap for bucket curl (7). When bucket curl function is actuated, pilot oil pressure shifts the bucket spool to the bucket regenerative valve position. Regenerative oil passes through an orifice (86) in the bucket spool.

NOTE: The operational principles of the boom and arm reduced leakage valves are identical. Therefore, boom reduced leakage valve operation is used as an example. Reduced leakage valves are used in the boom head end circuit and arm rod end circuit. The function of a reduced leakage valve is to reduce cylinder drift by stopping leakage from the cylinder back through the control valve. When the control valve is in neutral, the oil pressure generated by the load on the cylinders is applied to the spring end of boom reduced leakage valve (85) check valve through the boom reduced leakage valve switch valve. The check valve is held closed against the seat in housing trapping the oil from the cylinders at the work port.

600— High Pressure Oil 602— Low Pressure Supply Oil 604— Return Oil or Pressure-Free Oil

606— Trapped Oil 609— Pilot Oil

pressure from the cylinder is blocked by the switch valve. The oil pressure at the top (spring end) of the check valve can now flow through the pilot valve to the air bleed passage in the pilot caps and then to the hydraulic oil tank (31). The oil pressure from the cylinder pushes the check valve off its seat, opening the passage for oil to flow into the control valve return passage. The check valve is pushed off its seat because the OD of the upper land at the head end of check valve is slightly larger than at the lower land. The manual boom lower screw (2) is used to lower the boom if the engine should stop with the boom in the raised position. See Lower Boom with Engine Stopped. (Operator’s Manual.)

When a function is actuated, the pilot pressure (609) from pilot control valve (1) shifts the switch valve. The oil AS79221,00003D8 -19-18MAR11-2/2

Combined Operation—During combined operation of boom up, arm in, and swing, the arm regenerative solenoid is activated. When activated, control pilot oil shifts the switch valve of the arm 2 flow rate control valve.

600 604 Arm 2 Flow Rate Control Valve (normal operation)

With the switch valve shifted, high pressure oil is trapped on the backside of poppet, which forces the poppet towards the closed position. The poppet now restricts the flow of high pressure oil to arm 2 spool. Consequently, more pump 1 high pressure oil is available to the boom 1 spool, maintaining the boom up speed. During combined operation, the arm in function is maintained by the pump 2 high pressure oil and the arm 1 spool regenerative circuit. See Arm Regenerative Valve Circuit Operation.

Normal Operation—High pressure oil from pump 1 (17) opens the check valve (6) in the poppet of arm 2 flow rate control valve because the switch valve is open. The high pressure oil flows through the check valve and switch valve to the arm 2 spool. As load increases, pressure increases pushing the poppet open and high pressure oil flows through the poppet to arm 2 spool.

The purpose of the boom flow rate control valve (valve and poppet) (83) is to restrict supply oil in the circuit to ensure that there is sufficient supply oil for other functions during boom down and to restrict supply oil through boom 1 spool (81) during boom down so that boom regenerative valve (82) in boom 1 spool works properly.

During boom down and other functions, the boom lowers due to its own weight by the boom regenerative circuit and uses supply oil from the pump for other functions. This ensures that other functions maintain normal operation. See Boom Regenerative Valve Circuit Operation. (Group 9025-05.)

During boom down, the boom flow rate control valve restricts supply oil flow to the boom 1 spool from pump 1 (15). DF89619,00B574B -19-20JAN16-2/4

Normal Operation—When boom down is actuated, supply oil flows to the 4-spool side of the control valve from pump 1 (15). Supply oil opens the check valve (200) in the poppet (201) of the boom flow rate control valve (83) because the switch valve (203) is open due to no pilot oil pressure. Supply oil flows through boom flow rate control valve without any restriction and continues on to the boom 1 spool (81). 202— To Solenoid Valve Manifold Port DD 203— Switch Valve 204— From Boom Lower Meter-In Cut Valve 600— High-Pressure Oil 604— Return Oil

Theory of Operation

Combined Operation—When boom down is actuated, return oil (604) from the boom cylinders is under pressure from the weight of the boom. Return oil pressure causes boom lower meter-in cut valve to shift, routing boom down pilot oil to the boom flow rate control valve (83). See Boom Lower Meter-In Cut Valve Operation. (Group 9025-05.)

With the switch valve shifted, high-pressure oil (600) is trapped on the backside of poppet (201) which forces the poppet towards the closed position. The poppet now restricts the flow of high-pressure oil to boom 1 spool. Consequently, more pump 1 high-pressure oil is available to other functions.

202

When supply oil pressure to boom 1 spool is less than return oil pressure during boom down operation, the return oil shifts the boom regenerative valve (82) and combine with supply oil. See Boom Regenerative Valve Circuit Operation. (Group 9025-05.)

Swing Motor—The swing motor is a fixed-displacement, axial-piston motor consisting of swash plate (8), cylinder block (10), valve plate (11), housing (9), and swing park brake. Swing park brake consists of spring (1), brake piston (2), brake plate (3), and friction disc (4). Piston (5) is inserted into cylinder block which is splined to shaft (7).

Piston is pushed by pressurized oil from pump. Shoe (6) slides over swash plate so that cylinder block rotates. Shaft is splined to the first stage sun gear of swing reduction gear case. Therefore, the rotation of shaft is transmitted to the swing reduction gear case. See Swing Reduction Gear Case Operation. (Group 9025-05.)

Swing Motor Crossover Relief Valve—The swing motor crossover relief valves (54) are direct-acting relief valves with a shock-reducing function. Low-Pressure Relief Operation (shockless function): High pressure at port (24) flows into cavity (14) through poppet (21). Pressure oil from cavity (14) flows into cavities (18 and 19) via passages (15 and 16). Cavity (18) is larger than cavity (19) so that the piston moves to the left. A pressure difference is created from one side of the poppet to the other. When pressure difference is increased more than spring force, the poppet is open and pressure oil flows to port (23). When piston reaches full stroke the pressure difference is eliminated, the poppet is closed and the pressure in the swing circuit reaches set pressure. High-Pressure Relief Operation (overload prevention): After the piston is moved full stroke, the spring is compressed and circuit pressure becomes the

54— Crossover Relief Valve

set-pressure. If pressure at port (24) increases more than the spring set-pressure, the poppet is open and pressure oil flows to port (23). When pressure at port (24) is reduced to the specified level, the poppet is closed by the spring force. Swing Motor Make-Up Check Valve—When the swing control lever is returned to the neutral position while the upperstructure is in motion, the weight of the upperstructure continues to turn the swing motor which causes it to act like a pump. The flow caused by the pumping action of the swing motor cannot flow through the control valve because the work ports are blocked by the valve spool. The high-pressure oil is forced through the crossover relief valve. The make-up check valve (53) provides oil to the low-pressure side of the swing motor to prevent cavitation.

The function of swing damper valves A and B (5 and 6) is to relieve the pressure spike and aftershock at swing motor (17) when control valve swing spool (18) is returned to neutral. In neutral, the swing spool stops the flow of supply oil to the inlet side of swing motor and blocks the flow of return oil (604) from the return side. As the swing motor continues to rotate due to the inertia force of upperstructure, pressure in the return side increases momentarily. The inlet side of swing motor goes to a lower pressure. When the swing motor stops rotating, an aftershock or pressure increase is created at the inlet side of swing motor. The swing crossover relief valves and swing damper valves relieve the pressure increase and aftershock as shown by the time (1) to pressure (2) output curves. Between A and B (when relieving), the swing crossover relief valves, and swing damper valves operate as follows:

Swing Crossover Relief Valves: 1. High-pressure oil (600) of the pressure spike at return side of swing motor (17) is relieved to inlet side through the swing crossover relief valves. See Swing Motor, Crossover Relief Valve, and Make-Up Check Valve Operation. (Group 9025-05.) Swing Damper Valve A (5): 1. High-pressure oil pushes the ball (11) off seat of poppet (9) and then flows through the plunger (12) to chamber N (14). 2. Pressure in chamber N increases pushing the piston (15) against the plug. 3. When pressure increase becomes greater than the force of springs (8 and 13), plunger, ball, and poppet are pushed to the right compressing the springs. Swing Damper Valve B (6): 1. High-pressure oil flows through inner passage to spring chamber (16). 2. When pressure increase becomes greater than the force of springs, the piston, plunger, ball, and poppet are pushed to the left compressing the springs. The valves remain at this state until the high-pressure oil on return side of swing motor begins to decrease (B to C—pressure begins to decrease).

When swing motor (17) rotation due to the inertia force of upperstructure is reduced, the pressure spike at return side of swing motor also decreases. Between B and C (pressure begins to decrease) the swing damper valves operate as follows: Swing Damper Valve A (5): 1. When pressure spike at return side of swing motor (17) begins to decrease to medium-pressure oil (601),

pressure in chamber N (14) also begins to decrease. When pressure becomes less than force of spring (13), the plunger (12), is pushed to the left. 2. At the same time, poppet (9) is pushed to the left by its spring (8). Poppet moves more slowly because oil in chamber M (10) must flow through the orifice (7) causing pressure in chamber M to increase. 3. Therefore, the plunger moves away from the poppet, opening a passage for pressure oil to flow from the return side to inlet side of swing motor. 4. As pressure oil flows to the other side, pressure in the return side is controlled and aftershock is reduced. Swing Damper Valve B (6): 1. No operation between B to C—pressure begins to decrease. The valves remain at this state until the pressure spike at return side of swing motor decreases more (C to D—pressure at return side decreases).

Theory of Operation When swing motor (17) rotation due to the inertia of upperstructure is reduced, the pressure spike at return side of swing motor also decreases. Between C and D (pressure at return side decreases) the swing damper valves operate as follows: Swing Damper Valve A (5): 1. Poppet (9) continues to be pushed to the left by its spring (8) but moves slowly because oil in chamber M (10) must flow through the orifice (7) causing pressure in chamber M to increase. Swing Damper Valve B (6): 1. When pressure spike at return side of swing motor decreases to low-pressure oil (602), pressure in chamber N (14) also decreases. When pressure becomes less than force of spring (13), plunger (12) is pushed to the right. 2. At the same time, poppet (9) is pushed to the right by its spring (8). Poppet moves slowly because oil in chamber M (10) must flow through the orifice (7) causing pressure in chamber M to increase.

3. Therefore, the plunger moves away from the poppet, opening a passage for pressure oil to flow from the return side to inlet side of swing motor. Pressure oil now acts on ball (11) and poppet pushing the ball and poppet to the right compressing spring. 4. As the pressure oil flows to the inlet side, aftershock pressure in the return side is relieved promptly to the inlet side. The valves remain at this state until the aftershock pressure is sensed at the inlet side (D to E—during aftershock).

Theory of Operation When swing motor (17) stops rotating, the pressure spike at the inlet side of swing motor increases causing an aftershock. Between D and E (during aftershock) the swing damper valves operate as follows: Swing Damper Valve A (5): 1. Medium-pressure oil (601) from inlet side of swing motor, acts on ball (11) and poppet (9) through inner passage. Ball and poppet are pushed to the right compressing spring (8). Swing Damper Valve B (6): 1. Medium-pressure oil from inlet side of swing motor, pushes the ball off seat of poppet and oil flows through inner passage to the return side of swing motor.

The valves repeat these operations until pressure spike is controlled and aftershock is relieved. When pressures at the inlet and return side of swing motor decrease completely, the damper valves stop operating. MM16284,0000FE7 -19-19JAN16-8/8

Releasing Park Brake—When any dig or swing function is operated, the swing park brake release pilot valve is shifted allowing pilot pressure oil through check valve (4) to move brake piston (2). As brake piston moves, plate (7) and friction plate (6) disengage, which releases the swing park brake. Applying Park Brake—When the dig or swing control lever is returned to neutral, the swing park brake release pilot valve stops the flow of pilot oil to the swing motor.

6— Friction Plate 7— Plate 8— Cylinder Block

52— Swing Motor

The spring (1) pushes the brake piston down, forcing the oil through the orifice (3) into the swing motor case. The orifice prevents the brake piston from moving quickly and delays the application of the swing park brake until the upperstructure is stopped or nearly stopped. The spring force on the brake piston engages the friction plate (6), which acts on the cylinder block (8), and the plate (7), which acts on the inside of the swing motor housing, securing the upperstructure from moving.

When travel function is released, the counterbalance valve returns to center position blocking the supply oil acting on park brake piston (9). The disk spring pushing against the park brake piston forces the oil to flow through the orifice in the piston and into propel motor housing. The delay caused by oil flowing through the orifice is enough to slow engagement to ensure that park brake is only fully applied after the machine has stopped.

Counterbalance Valve (71)—When the travel spools in the control valve are in neutral, counterbalance valve is held in the center position by springs (17). Both travel motor work ports (75A and 75B) are open to return through the control valve return passage. The check valves (69) and counterbalance valve traps the oil in each motor holding them stationary. When travel function is first actuated, supply oil (600) pressure builds on one side of motor due to the motor's resistance to turning and because the check valve and counterbalance valve blocks the flow of return oil (604) from the motor. The increased pressure is sensed at the end of counterbalance valve through orifice (70) and begins to shift the counterbalance valve. As the valve shifts, a path is opened for return oil to flow to the control valve. Supply oil flows to the park brake piston (14) to release the travel park brake (64). Supply oil flows around counterbalance valve and opens the check valve to supply the motor. When a machine is traveling down a hill, the weight can cause it to overrun the travel motors. Overrunning would cause faster travel than desired and cavitation in the motors. As pressure decreases in the work port

of motor, the spring begins to shift the counterbalance valve towards the neutral position. A restriction is created restricting the flow of return oil from the motor and keeps the motor from turning faster than desired. Travel Motor Crossover Relief Valves (68)—The crossover relief valves are direct acting relief valves with a shock reducing function. As oil flows through the orifice (13) and moves the piston (14), a pressure difference is created from one side of the poppet (12) to the other. The pressure difference allows the poppet to open below the set pressure to reduce pressure spikes. Once the piston reaches full stroke, the pressure difference is eliminated and the pressure in the travel circuit increases to the set pressure. Check Valves (69)—When the travel control lever is returned to the neutral position while the machine is in motion, the inertia of machine continues to turn the travel motor which causes it to act like a pump. High pressure oil is then created in the return side of motor and low pressure oil (602) on the other. When pressure in the return side becomes higher than the low pressure side of motor, the check valve is pushed open. Return oil from the return side flows to low pressure side preventing cavitation.

Power Dig/Travel Speed Solenoid (marked SG) (Y24)—is a proportional type solenoid valve. The solenoid valve is actuated by a voltage signal from the main controller (MCZ). The voltage signal is a DC voltage that is turned on and off to form a pulse width modulated signal. The solenoid (1) coil reacts to the “average” voltage to create a magnetic force to shift the spool (2) left against a spring. The reduced pilot oil (613) pressure sent to the valve function (3) depends on how long the voltage signal is on versus on how long it is off. The reduced pilot oil pressure is in proportion to the voltage signal. When de-energized (7), the spool is pushed to the right by a spring. The valve function port is connected to the hydraulic oil tank (31) port.

regulator valve (30) flows past the spool flange and out the valve function port as reduced pilot oil. Because the flange on the right is larger than the flange on the left, the spool is pushed to the right against the magnetic force as the oil pressure to the valve function increases. When the oil pressure becomes equal to or greater than the magnetic force, the spool is pushed to the right closing the passage stopping the pressure increase. The oil pressure to the valve function is trapped. The spool is moving constantly to maintain the oil pressure in response to the voltage signal to the solenoid coil. See Control Valve Operation (Group 9025-05.) and see Main Controller (MCZ) Circuit Theory of Operation. (Group 9015-15.)

When energized (6), the magnetic force shifts the spool left against the spring. Pilot oil (609) from the pilot pressure DF89619,00B58AE -19-01MAY15-4/4

Boom, Arm, and Bucket Cylinders The boom, arm, and bucket cylinders are similar in design.

A buffer ring (5), U-cup seal (4), backup ring (3), and wiper seal (2) are used in the rod guide. A snap ring (1) is used to help hold wiper seal in place. The U-cup seal (4) is protected against high pressure by the buffer ring (5) and stops the small amount of oil that may pass by the buffer ring. The piston (8) is a slip fit on the cylinder rod (16) and is retained with a nut (13). A set screw (12) prevents loosening of the nut. The piston is fitted with a cap seal (11), wear rings (10), and buffer rings (9).

Boom, bucket, and arm cylinders have a cushion (14) in front of the piston to provide cushioning action in cylinder extension. As the cylinder nears the end of its stroke, the cushion enters a bore in the rod guide. The remaining return oil ahead of the piston must flow through a small clearance between the cushion and rod guide. Only the arm cylinder is cushioned in retraction. The end of the rod enters a bore in the head end of cylinder. The remaining return oil ahead of the piston and nut must flow through this small clearance as the cylinder bottoms out in this direction.

During bypass operation, oil flows into chamber faster than it can flow through the filter element, causing pressure to increase. The higher pressure forces bypass valve open allowing oil to flow down center of filter element and into hydraulic oil tank. The bypass valve closes when pressure decreases below pressure setting of bypass valve.

A bypass valve (3) is located at the top of filter. The valve opens to protect filter element against pressure surges JA66566,0002660 -19-03AUG12-1/1

One pilot control valve is used to control the auxiliary functions. The pilot control valve contains two valve assemblies. The valves are controlled by movement of the pedals against the plunger (4). The ports (10, 11, and 12) in housing are identified by numbers and letters next to each port. In neutral, the spool is pushed up by the return spring (9) pushing the plunger up. The return springs hold the pedal in the neutral position. With the spool up, ports 13 and 14 to the control valve pilot cap (12) are open to pilot shutoff solenoid valve port T2 (10) through the passage and holes in spool. Pilot oil from the pilot shutoff solenoid valve port A3 (11) is blocked by the spool. When the pedal is pushed to actuate an auxiliary function, the pedal pushes the plunger and spring guide down against the return spring and balance spring. The balance spring pushes the spool down. As the spool is pushed down and the holes move through the deadband area, the

passage from control valve pilot cap to the hydraulic oil tank is closed and then opened to the pilot oil from pilot shutoff solenoid valve. Pilot oil pressure increases until it is equal to the force applied by the balance spring pushing the spool moves up until the oil flow through the holes is blocked in the deadband area. With the oil flow blocked, the control valve spool is held stationary until the pedal is again actuated. When the pedal is pushed to full stroke, the plunger is pushed down farther by the balance spring opening the passage through the spool to pilot oil pressure. When pressure to the control valve pilot cap is equal to the force applied by the balance spring, the spool moves up until it contacts the plunger. The plunger holds the spool down so the passage through the spool remains open to pilot oil pressure. Oil pressure to the control valve pilot cap now approximately equals pilot oil pressure.

Theory of Operation

Flow Rate Select Solenoid Valve Operation 41B 93 118

The function of the flow rate select solenoid valve (156) is to allow for combined oil flow from pump 1 and pump 2, and to provide more or less priority to the functions under the following conditions:

41A

• Two-speed on (combined flow on) • Pressure on attachment pressure sensor (B60)

108

Y44

Y43

Combined with any of these inputs:

• Pressure on arm out pressure sensor (B61) • Pressure on arm out pressure sensor (B61) and boom up pressure sensor (B30)

37

• Pressure on swing pressure sensor (B33) • Pressure on travel pressure sensor (B34)

TX1135894 —UN—21AUG13

219

For more information on sensors, see System Functional Schematic. (Group 9015-10.) NOTE: Two-Speed control will not work properly unless appropriate kits are installed on machine.

156

When energized, solenoid valve (Y43) sends pilot oil from pilot signal manifold port SM (41A), to pilot signal manifold port SP (41B), to bypass shutoff valve (93), and to auxiliary function flow combiner valve (118). Pilot oil sent to auxiliary function flow combiner valve allows for combined oil flow from pump 1 and pump 2 to operate the attachment. Pilot oil to pilot signal manifold port SP shifts the pump 1 flow rate pilot valve to send full control pressure to pump 1 and bypass shutoff valve allowing pump 1 pressure to increase. When de-energized, 2-speed activation solenoid valve spring tension shifts the valve allowing the circuit to drain to hydraulic oil tank (219).

Flow Rate Select Solenoid Valve Schematic (2-speed solenoid energized)

When energized, the flow rate adjustment solenoid valve (Y44) routes pilot oil from solenoid valve manifold port PE (37) to auxiliary flow rate control valve (108). This adjusts the auxiliary flow rate control valve to provide more or less priority to the swing and travel functions over the attachment function. The main controller varies the signal to the flow rate adjustment solenoid valve to vary the pilot oil pressure at the auxiliary flow rate control valve. This

Theory of Operation

Flow Rate Pressure Reducing Valve Operation

74

The function of the flow rate reducing valve (157) is to control the amount of pump 1 flow that is directed to the auxiliary spool when combining auxiliary with a pump 1 function. Pilot pressure is sent from pilot signal manifold port SN (41) when a pump 1 function is activated. The pilot oil is then routed through the flow rate pressure reducing valve (157) to control valve port SN (74). This shifts the auxiliary flow combiner valve to stop the flow of pump 1 high-pressure oil to the auxiliary spool, “de-combining” the flow. Flow rate reducing valve is adjustable, turn counterclockwise to give auxiliary priority flow over pump 1 functions or clockwise to give pump 1 functions priority over auxiliary. When pilot oil pressure to control valve port SN exceeds set pressure of flow rate reducing valve, the valve shifts allowing pilot oil to control valve port SN to flow to hydraulic oil tank (219) allowing the auxiliary flow combiner valve to shift combining pump 1 and pump 2 high-pressure oil flow. For more information, see Two Pump Combined Flow Kit Operation. (Group 9025-05.)

Secondary Auxiliary Relief Valve Solenoid Valve Operation

158

The secondary auxiliary relief valve solenoid valve is controlled by settings in MP Dr and Service ADVISOR™. See Attachment Control Circuit Theory of Operation. (Group 9015-15.) When the secondary auxiliary relief valve solenoid valve (158) is activated, valve is shifted and pilot oil from solenoid valve manifold port PE (218) is sent to secondary auxiliary relief control valve (160). This shifts the secondary auxiliary relief control valve to route high-pressure oil to the secondary auxiliary relief valve. When the secondary auxiliary relief valve solenoid valve is deactivated, spring tension shifts the valve. Pilot oil to secondary auxiliary relief control valve is sent to hydraulic oil tank (219). This shifts the secondary auxiliary relief control valve to stop routing high-pressure oil to the secondary auxiliary relief valve.

The function of the secondary auxiliary relief control valve (160) is to open or close flow of high-pressure oil from auxiliary attachment (150) to secondary auxiliary relief valve (159). When secondary auxiliary relief valve solenoid valve energizes, pilot oil is sent from secondary auxiliary relief valve solenoid valve (158) shifting secondary auxiliary relief control valve to open the circuit allowing high-pressure oil flow to secondary auxiliary relief valve. When secondary auxiliary relief valve solenoid valve de-energizes, pilot oil from secondary auxiliary relief valve solenoid valve is routed to hydraulic oil tank and spring tension closes secondary auxiliary relief control valve circuit.

Secondary Auxiliary Relief Valve Operation

At pressures below the circuit relief setting, spring tension in the secondary auxiliary relief valve closes flow of auxiliary high-pressure oil from auxiliary attachment to hydraulic oil tank. When pressure exceeds the secondary auxiliary relief valve setting, auxiliary high-pressure oil overcomes spring tension and shifts secondary auxiliary relief valve, opening flow of auxiliary high-pressure oil from auxiliary attachment (160) to hydraulic oil tank. For more information, see Secondary Auxiliary Relief Kit Operation. (Group 9025-05.)

Auxiliary Secondary Relief Solenoid Valve Energized— When the secondary relief solenoid valve (Y41) is energized, the secondary auxiliary relief valve solenoid valve shifts to allow pilot oil (609) to flow to secondary auxiliary relief control valve (160). Pilot oil shifts secondary auxiliary relief control valve, allowing high-pressure oil (600) from auxiliary attachment work port (217) to secondary auxiliary relief valve (159). When pressure from auxiliary attachment work port (217) exceeds set point, secondary auxiliary relief valve (159) opens to allow high-pressure oil (600) to flow to hydraulic oil tank (219).

General Hydraulic Oil Cleanup Procedure ESSENTIAL TOOLS JDG10712 Super Caddy™

TX1035521A —UN—25JAN08

This procedure is to be used on machines that have had hydraulic system repair without a catastrophic component failure. Filter caddy procedure must be done prior to starting machine after a component has been repaired or replaced. IMPORTANT: Intermixing of oils can cause premature hydraulic component damage and oil contamination. Oil types and filters must not be intermixed. Use filter element in same type oil to avoid intermixing of oils.

Hydraulic Tank Cap

Oil contamination could result if filter caddy is used in dusty or wet conditions. Clean work practices and cleanliness of filter caddy and attachments are critical when filtering oil. TX1035522A —UN—25JAN08

NOTE: Filter oil should be at 27°C (80°F) or above for best Super Caddy performance. Reduce flow rate to filter oil below 27°C (80°F). Super Caddy requires a 20-amp electric circuit. Use of electrical extension cord is not recommended. 1. Park machine on a flat, level surface with attachments lowered to the ground and turn engine off. See Park and Prepare for Service Safely. (Group 0001.)

Hydraulic Tank and Wands 1— Hydraulic Oil Tank Pressure Release Button 2— Hydraulic Oil Tank Cap 3— Cover

CAUTION: Avoid personal injury from high-pressure fluid. High-pressure release of oil from pressurized system can cause serious burns or penetrating injury. Relieve pressure from hydraulic system before servicing.

4— Suction Wand 5— Discharge Wand

CAUTION: Prevent possible personal injury from unexpected machine movement. Clear all persons from area before operating machine.

2. Release hydraulic oil tank pressure by pressing pressure release button at top of hydraulic oil tank. See Hydraulic Oil Tank Pressure Release Procedure. (Group 9025-25.)

Avoid entanglement and possible electrocution from filter caddy power cord. Do not operate machine while filter caddy is connected to machine.

3. Remove hydraulic oil tank cap (2). NOTE: When installing suction and discharge wands (4 and 5) into the hydraulic oil tank, locate the submerged ends of the wands as far away from each other as possible to ensure maximum oil movement during cleanup procedure.

8. Make sure machine is parked in an area that will allow all hydraulic functions to be operated. 9. Fill hydraulic oil tank to operating level.

4. Install JDG10712 Super Caddy discharge wand (5) and suction wand (4) into hydraulic oil tank. 5. Cover the wands and tank openings with a plastic tarp to prevent contamination.

10. Run machine at slow idle. Operate each circuit a minimum of 2 minutes in each direction to flush any remaining contaminants back through hydraulic system filters.

6. Remove residual oil contaminants using JDG10712 Super Caddy.

11. Stop engine. Install Super Caddy to machine as before.

7. When cleaning process is done, disconnect Super Caddy from machine. Continued on next page

Tests

12. Repeat Super Caddy operation procedure until contaminant value is at specifications. Refer to operator’s manual included with Super Caddy or see Super Caddy in Service ADVISOR™ for operating procedure.

NOTE: Instrument cleanliness and clean work practices are critical when taking oil samples. Dust, wind, and moisture, as well as contaminated sample pumps, bottles, and tubing can affect results.

13. When oil reaches an acceptable level of cleanliness, disconnect Super Caddy from machine.

16. Obtain oil sample for fluid analysis. Oil sample must be taken from system before oil passes through the filter when oil is warm.

14. Install new hydraulic oil filters.

17. Fill hydraulic oil tank to proper operating level.

15. Clean hydraulic oil tank pressure release button and install hydraulic oil tank cap.

18. Return machine to service.

CAUTION: Avoid possible serious injury from machine movement during warm-up procedure. Clear the area of all bystanders before doing the warm-up procedure. 2. Clear the area of all bystanders to allow for machine movement. 3. Run machine at specification for approximately 5 minutes before operating any functions.

IMPORTANT: If machine temperature is below -18°C (0°F), start procedure in the ECO (economy) mode. Failure to do this could cause pump cavitation. Once oil temperature is above -18°C (0°F), the power mode can be switched to H/P (high power) mode. Below -18°C (0°F) an extended warm-up period may be necessary. Hydraulic functions will move slowly and lubrication of parts may not be adequate with cold oil. Do not attempt normal machine operation until hydraulic functions move at or close to normal cycle times. Operate functions slowly and avoid sudden movements until engine and hydraulic oils are thoroughly warmed. Operate a function by moving it a short distance in each direction. Continue operating the function increasing the distance traveled in each cycle until full stroke is reached. For faster warm-up, restrict air flow through oil cooler using cardboard or other similar material. Use correct viscosity oil to minimize warm-up period. See Hydraulic Oil. (Operator's Manual.) 1.

5— Expansion Valve 6— Receiver-Dryer 7— High-Pressure Liquid

8— High-Pressure Gas 9— Low-Pressure Liquid 10— Low-Pressure Gas

The compressor (2) is belt driven and engaged by an electromagnetic clutch. The air conditioner circuit automatically controls compressor engagement or disengagement when system is in operation. The compressor draws low-pressure gas (10) from evaporator (1) and compresses it into high-pressure gas (8). High-pressure gas causes temperature of refrigerant to rise higher than outside air temperature. High-pressure gas leaves compressor and flows through condenser (3). Inside condenser, heat is removed and transferred to outside air that is drawn through condenser core by the fan. Cooling refrigerant causes it to condense, and refrigerant leaves condenser as high-pressure liquid (7).

High-pressure liquid flows into receiver-dryer (6), where moisture and contaminants (acid, solids, etc.) are removed. The receiver-dryer contains a color moisture indicator. (Blue) indicates no moisture is present. (Pink) indicates moisture is present. Should moisture be combined with refrigerant, hydrofluoric and hydrochloric acids are formed. These acids are corrosive to metal surfaces, and leakage will eventually develop. The receiver-dryer also stores refrigerant, allowing a longer period of time before additional refrigerant is needed. Refrigerant hoses allow a small amount of refrigerant to migrate through their walls.

Theory of Operation

Refrigerant flows from receiver-dryer through expansion valve (5) to the evaporator. The expansion valve senses refrigerant temperature and pressure to modulate refrigerant flow, which then changes refrigerant to low-pressure liquid (9) entering evaporator. Actual cooling and drying of cab air takes place at evaporator. Heat absorbed by evaporator and transferred to refrigerant causes refrigerant to vaporize into low-pressure gas. Low-pressure gas is drawn from evaporator by compressor and cycle is repeated.

is drained away through drain tubes connected to a drain pan under evaporator.

A freeze control switch senses temperature of evaporator coil through a capillary tube. This prevents the evaporator from becoming cold enough to freeze moisture that condenses on the evaporator coil. Condensed moisture

For location of machine heater and air conditioning components, see Heater and Air Conditioner Component Location. (Group 9031-15.)

System pressure is monitored by a high/low-pressure switch, located on high-pressure side of expansion valve. If pressure becomes too high or too low, the switch opens and stops the compressor, interrupting the cycle. The engine cooling fan increases to 1200 rpm for increased flow across the condenser when ambient air is over 18°C (64°F) and air conditioner is on.

Tests R134a Refrigerant Cautions and Proper Handling

If skin freezes to container, pour COOL water over container to free the skin. Go to a physician or hospital immediately for treatment.

SERVICE EQUIPMENT AND TOOLS Refrigerant Identifier

CAUTION: DO NOT allow liquid refrigerant to contact eyes or skin. Liquid refrigerant will freeze eyes or skin on contact. Wear goggles, gloves, and protective clothing. If liquid refrigerant contacts eyes or skin, DO NOT rub the area. Splash large amounts of COOL water on affected area. Go to a physician or hospital immediately for treatment.

IMPORTANT: To meet government standards relating to the use of refrigerants, R134a is used in the air conditioning system. Because it does not contain chlorine, R134a is not detrimental to the ozone in the atmosphere. However, it is illegal to discharge any refrigerant into the atmosphere. It must be recovered using the appropriate recovery stations. Use correct refrigerant recovery, recycling, and charging stations. Do not mix refrigerants, hoses, fittings, components, or refrigerant oils.

DO NOT allow refrigerant to contact open flames or very hot surfaces such as electric welding arc, electric heating element, and lighted smoking materials.

Use only John Deere approved R134a refrigerant products. Mixing of products not compatible will cause system damage and contaminate recovery, recycling, and charging station equipment. Care must be taken to identify and use equipment, refrigerant oil, and refrigerant designed only for R134a refrigerant systems. Refrigerant should be tested for type and purity before recovery, recycling, or charging of system. Refrigerant identifier should be used before any testing or repair to system is performed.

DO NOT heat refrigerant over 52°C (125°F) in a closed container. Heated refrigerant will develop high pressure which can burst the container. Keep refrigerant containers away from heat sources. Store refrigerant in a cool place. DO NOT handle damp refrigerant container with bare hands. Skin may freeze to container. Wear gloves.

tubing, or fittings and cannot be removed by cleaning, then replace parts.

IMPORTANT: Hoses used for air conditioning systems contain special barriers in its walls to prevent migration of refrigerant gas.

IMPORTANT: Chlorinated solvents (such as trichloroethylene) are contaminants, and must not be used for cleaning. The use of these solvents will cause deterioration of hoses.

Do not use hydraulic hoses as replacement hoses in the air conditioning system. Only use certified hose meeting SAE J2064 requirements. When a component is disconnected from the system, special care should be given to inspecting hoses and tubing for moisture, grease, dirt, rust, or other foreign material. If such contamination is present in hoses,

Fittings that have grease or dirt on them should be wiped clean with a cloth dampened with alcohol. To assist in making leak-proof joints, use a small amount of clean, correct viscosity refrigerant oil on all hose and tube connections. Dip O-rings in correct viscosity oil before assembling.
