Terminology
WIRING DIAGRAM A wiring diagram shows, as closely as possible, the actual location of all component parts of the device. The open terminals (marked by an open circle) and arrows represent connections made by the user. Since wiring connections and terminal markings are shown, this type of diagram is helpful when wiring the device or tracing wires when troubleshooting. Bold lines denote the power circuit and thin lines are used to show the control circuit. Black wires are conventionally used in power circuits and red wire in control circuits for AC magnetic equipment. A wiring diagram is limited in its ability to completely convey the controller’s sequence of operation. The elementary diagram is used where an illustration of the circuit in its simplest form is desired.
ELEMENTARY DIAGRAM An elementary diagram is a simplified circuit illustration. Devices and components are not shown in their actual positions. All control circuit components are shown as directly as possible, between a pair of vertical lines representing the control power supply. Components are arranged to show the sequence of operation of the devices and how the device operates. The effect of operating various auxiliary contacts and control devices can be readily seen. This helps in troubleshooting, particularly with the more complex controllers. This form of electrical diagram is sometimes referred to as a “schematic” or “line” diagram.

Examples of Control Circuits 2- and 3-Wire Control Elementary Diagrams Low Voltage Release and Low Voltage Protection are the basic control circuits encountered in motor control applications. The simplest schemes are shown below. Other variations shown in this section may appear more complicated, but can always be resolved into these two basic schemes. Note: The control circuits shown in this section may not include overcurrent protective devices required by applicable electrical codes. See page 11 for examples of control circuit overcurrent protective devices and their use.

PILOT DEVICE SUCH AS LIMIT SWITCH, PRESSURE SWITCH, ETC.
Low voltage release is a 2-wire control scheme using a maintained contact pilot device in series with the starter coil. This scheme is used when a starter is required to function automatically without the attention of an operator. If a power failure occurs while the contacts of the pilot device are closed, the starter will drop out. When power is restored, the starter will automatically pickup through the closed contacts of the pilot device. The term “2-wire” control is derived from the fact that in the basic circuit, only two wires are required to connect the pilot device to the starter.
Low voltage protection is a 3-wire control scheme using momentary contact push buttons or similar pilot devices to energize the starter coil. This scheme is designed to prevent the unexpected starting of motors, which could result in injury to machine operators or damage to the driven machinery. The starter is energized by pressing the Start button. An auxiliary holding circuit contact on the starter forms a parallel circuit around the Start button contacts, holding the starter in after the button is released. If a power failure occurs, the starter will drop out and will open the holding circuit contact. When power is restored, the Start button must be operated again before the motor will restart. The term “3-wire” control is derived from the fact that in the basic circuit, at least three wires are required to connect the pilot devices to the starter.

A Hand-Off-Auto selector switch is used on 2-wire control applications where it is desirable to operate the starter manually as well as automatically. The starter coil is manually energized when the switch is turned to the Hand position and is automatically energized by the pilot device when the switch is in the Auto position.

When a motor must be started and stopped from more than one location, any number of Start and Stop push buttons may be wired together. It is also possible to use only one Start-Stop station and have several Stop buttons at different locations to serve as an emergency stop.

As an operator safety precaution, a step-down transformer can be used to provide a control circuit voltage lower than line voltage. The diagram above shows one way to provide overcurrent protection for control circuits.
A starter coil with a high VA rating may require a control transformer of considerable size. A control relay and a transformer with a low VA rating can be connected so the normally-open relay contact controls the starter coil on the primary or line side. Square D Size 5 Combination Starter Form F4T starters use this scheme.

Examples of Control Circuits 3-Wire Control Elementary Diagrams Jogging: Selector Switch and Start Push Button FIG. 1
Jogging: Selector Push Button FIG. 2
FPO 7-2 FPO 7-1
Jogging, or inching, is defined by NEMA as the momentary operation of a motor from rest for the purpose of accomplishing small movements of the driven machine. One method of jogging is shown above. The selector switch disconnects the holding circuit contact and jogging may be accomplished by pressing the Start push button.
A selector push button may be used to obtain jogging, as shown above. In the Run position, the selector-push button provides normal 3-wire control. In the Jog position, the holding circuit is broken and jogging is accomplished by depressing the push button.
Jogging: Control Relay
Jogging: Control Relay for Reversing Starter
FIG. 3
FIG. 4
FPO 7-4
FPO 7-3 When the Start push button is pressed, the control relay is energized, which in turn energizes the starter coil. The normallyopen starter auxiliary contact and relay contact then form a holding circuit around the Start push button. When the Jog push button is pressed, the starter coil is energized (independent of the relay) and no holding circuit forms, thus jogging can be obtained.
This control scheme permits jogging the motor either in the forward or reverse direction, whether the motor is at standstill or rotating. Pressing the Start-Forward or Start-Reverse push button energizes the corresponding starter coil, which closes the circuit to the control relay.The relay picks up and completes the holding circuit around the Start button. As long as the relay is energized, either the forward or reverse contactor remains energized. Pressing either Jog push button will deenergize the relay, releasing the closed contactor. Further pressing of the Jog button permits jogging in the desired direction.

When one Start-Stop station is required to control more than one starter, the scheme above can be used. A maintained overload on any one of the motors will drop out all three starters.

FPO 7-6 3-wire control of a reversing starter can be implemented with a Forward-Reverse-Stop push button station as shown above. Limit switches may be added to stop the motor at a certain point in either direction. Jumpers 6 to 3 and 7 to 5 must then be removed.
Examples of Control Circuits 3-Wire Control Elementary Diagrams 3-Wire Control: Reversing Starter Multiple Push Button Station
3-Wire Control: Reversing Starter w/ Pilot Lights to Indicate Motor Direction FIG. 2
FIG. 1
More than one Forward-Reverse-Stop push button station may be required and can be connected in the manner shown above.
3-Wire Control: 2-Speed Starter
Pilot lights may be connected in parallel with the forward and reverse contactor coils, indicating which contactor is energized and thus which direction the motor is running.
3-Wire Control: 2-Speed Starter w/ 1 Pilot Light to Indicate Motor Operation at Each Speed FIG. 4
FIG. 3
3-wire control of a 2-speed starter with a High-Low-Stop push button station is shown above. This scheme allows the operator to start the motor from rest at either speed or to change from low to high speed. The Stop button must be operated before it is possible to change from high to low speed. This arrangement is intended to prevent excessive line current and shock to motor and driven machinery, which results when motors running at high speed are reconnected for a lower speed.
One pilot light may be used to indicate operation at both low and high speeds. One extra normally-open auxiliary contact on each contactor is required. Two pilot lights, one for each speed, may be used by connecting pilot lights in parallel with high and low coils (see reversing starter diagram above).
Plugging: Plugging a Motor to a Stop from 1 Direction Only
Anti-Plugging: Motor to be Reversed but Must Not be Plugged
FIG. 5
Plugging is defined by NEMA as a braking system in which the motor connections are reversed so the motor develops a counter torque, thus exerting a retarding force. In the above scheme, forward rotation of the motor closes the normally-open plugging switch contact and energizing control relay CR. When the Stop push button is operated, the forward contactor drops out, the reverse contactor is energized through the plugging switch, control relay contact and normally-closed forward auxiliary contact. This reverses the motor connections and the motor is braked to a stop. The plugging switch then opens and disconnects the reverse contactor. The control relay also drops out. The control relay makes it impossible for the motor to be plugged in reverse by rotating the motor rotor closing the plugging switch. This type of control is not used for running in reverse.
FIG. 6
Anti-plugging protection is defined by NEMA as the effect of a device that operates to prevent application of counter-torque by the motor until the motor speed has been reduced to an acceptable value. In the scheme above, with the motor operating in one direction, a contact on the anti-plugging switch opens the control circuit of the contactor used for the opposite direction. This contact will not close until the motor has slowed down, after which the other contactor can be energized.

Examples of Control Circuits Shunting Thermal Units During Starting Period Elementary Diagrams Shunting Thermal Units During Starting Period FIG. 1
Article 430-35 of the NEC describes circumstances under which it is acceptable to shunt thermal units during abnormally long accelerating periods. 430-35. Shunting During Starting Period. (a) Nonautomatically Started. For a nonautomatically started motor, the overload protection shall be permitted to be shunted or cut out of the circuit during the starting period of the motor if the device by which the overload protection is shunted or cut out cannot be left in the starting position and if fuses or inverse time circuit breakers rated or set at not over 400 percent of the full-load current of the motor are so located in the circuit as to be operative during the starting period of the motor.
FPO 9-1
(b) Automatically Started. The motor overload protection shall not be shunted or cut out during the starting period if the motor is automatically started.
Exception. The motor overload protection shall be permitted to be shunted or cut out during the starting period on an automatically started motor where: (1) The motor starting period exceeds the time delay of available motor overload protective devices, and (2) Listed means are provided to: a. Sense motor rotation and to automatically prevent the shunting or cut out in the event that the motor fails to start, and b. Limit the time of overload protection shunting or cut out to less than the locked rotor time rating of the protected motor, and c. Provide for shutdown and manual restart if motor running condition is not reached. Figures 1 and 2 show possible circuits for use in conjunction with 3-wire control schemes. Figure 1 complies with NEC requirements. Figure 2 exceeds NEC requirements, but the additional safety provided by the zero speed switch might be desirable. Figure 3 shows a circuit for use with a 2-wire, automatically started control scheme that complies with NEC requirements. UL or other listed devices must be used in this arrangement.

Auxiliary contacts on contactors, relays and push button contacts use 2-digit terminal designations, as shown in the diagram above. The first digit indicates the location of the contact on the device. The second digit indicates the status of the contacts, N.O. or N.C. “1” and “2” indicate N.C. contacts. “3” and “4” indicate N.O. contacts.
96 98 With Non-Isolated N.O. Alarm Contact
Overload contact terminals are marked with two digits. The first digit is “9”. The second digits are “5” and “6” for a N.C. and “7” and “8” for a N.O. isolated contact. If the device has a non-isolated alarm contact (single pole), the second digits of the N.O. terminals are “5” and “8”.

To find Kilowatts KVA Horsepower (output) Amperes when Horsepower is known
E=Volts
l = Amperes
%Eff = Percent efficiency
PF = Power factor
HP = Horsepower
KVA = Kilovolt-Amps
Average Efficiency and Power Factor Values of Motors: When actual efficiencies and power factors of the motors to be controlled are not known, the following approximations may be used: Efficiencies: DC motors, 35 hp and less: DC motors, above 35 hp: Synchronous motors (at 100% PF):
80% to 85% 85% to 90% 92% to 95%
“Apparent” efficiencies (Efficiency x PF): 3-phase induction motors, 25 hp and less: 3-phase induction motors above 25 hp: Decrease these figures slightly for single phase induction motors.
