3.7 Terminology Pulsations Pulsation means opening and closing the teat liners in the teat cups. This occurs when the valve system, the pulsator, alternately admits atmospheric air and air from the vacuum system into the chamber between the liner and cup. The teat liner opens when vacuum is created in the space between the teat liner and the teat cup. If atmospheric air is allowed to enter this space the teat liner will close. Most pulsators can be classified as follows: 路
Relay pulsators where a central pulsation unit controls pulsation rate and ratio.
路
Stand alone pulsators with a built-in pulsation control unit.
Pulsators can control all 4 teat cups simultaneously - Simultaneous system. Pulsators can control 4 teat cups in pairs - Alternate system. Alternate pulsation: The alternate cyclical movement of half the number of teat liners on the same milking cluster. Atmospheric pressure phase: How long atmospheric pressure is present in the pulsation area (d-phase) expressed as a percentage of the entire pulsation stroke. Cascade: A method where solenoids in the pulsators are controlled in sequence so that only a certain number of solenoids (with the Lectron 612 system usually a third of the total number) are activated at a certain time. The aim is to reduce the vacuum demand for the pulsation compared
D105018
14
10/03-1.0
to the demand with a simultaneous setting (simultaneous activation of all the pulsators). Compensating pulsation: Milking with a different pulsation ratio on the front and rear teats. Equal pulsation ratio: The same pulsation ratio on the front and rear teats. Maximum vacuum phase: How long maximum vacuum is present in the pulsation area (bphase) expressed as a percentage of the entire pulsation stroke. Milking phase: The part of the pulsation stroke where the teat liner is open. Milk flows out of the teat during this phase. Pair ratio: The difference in pulsation ratio between both pairs of teat cups in the same milking cluster, for example with alternate milking, expressed as a percentage Pulsation characteristic: A graph illustrating the progress of the vacuum level and the vacuum signal in the pulsation zone. Pulsation zone: Space between the teat liner and the teat cup. Pulsation zone vacuum registration: Each period of pulsation zone vacuum expressed as follows: a. Vacuum increase phase- teat liner opens b. Maximum vacuum phase -teat liner fully opened c. Vacuum decrease phase- teat liner closes d. Minimum vacuum phase- teat liner fully closed The duration of each phase, expressed as a percentage of the entire pulsation stroke, is measured at points where registration cuts through the abcis (y-axis) at a level of 4 kPa below nominal vacuum and above atmospheric pressure. Pulsation stroke: A complete cyclical movement of a teat liner. Pulsation rate: The number of pulsations per minute. Pulsation control unit: A mechanism that controls one or more pulsator(s). In the first instance the mechanism is built into one pulsator (stand-alone pulsator); in the second case the installation is separate and the mechanism controls several pulsators. Pulsation ratio: The duration of a vacuum increase (a- phase) + the duration of the maximum vacuum level (b-phase) in relation to the duration of the vacuum decrease (c-phase) + the duration of the minimum vacuum level (d-phase) in the space between the teat liner and teat cup (pulsation zone) expressed as a percentage of the total pulsation stroke. The pulsation ratio is expressed as follows: a+b a+b+c+d

D105018
Rest phase: The part of the pulsation stroke when the teat liner is closed. There is no vacuum on the teat. Simultaneous pulsation: The synchronous cyclical movement of all teat liners in the same milking cluster. Pulsation air usage per milking cluster: The amount of air used by the pulsation system per milking cluster during milking. Required average airflow: The required amount of airflow, taking into account any narrowing on the route between the milking cluster and the pulsation lines (e.g. a narrowing is caused where the pulsator is connected to the pulsation lines).

4 Switching on / off The Isolator Xp milk flow sensor can be switched on or off using the switch on the power supply unit. With normal operation the power is never switched off. If the Isolator Xp milk flow sensor is in Pause mode (in other words non-milking mode) the system will deactivate both solenoids (one for the Isolator Xp sensor, the other in the automatic cluster removal). If an Aquastar Water management system is part of the installation, these actions take place automatically. If there is no Aquastar system present, the switch actions are done manually using the external switch.

5 Working The Gascoigne Melotte Isolator Xp Automatic Cluster Removal system comprises 2 main parts: ·
The Isolator Xp milk flow sensor including control system, internal pulsation and milk flowcontrolled stimulation
·
The automatic cluster removal
The system is controlled by the condition of the cow’s milk flow, using conductivity measured between 2 probes. The illustration below shows the front of the sensor and the position of both probes in the milk chamber, plus the 5 visible LEDs. The Isolator Xp milk automatic cluster removal measures the milk flow between both probes and uses the conductive properties of the milk; if there is milk between both probes the electrical current is transmitted from one probe to the other, thereby completing the circuit. If there is no milk between the probes the current is interrupted. The percentage of time that milk is sensed between both probes is measured over a continuous time window of 30 sec.

If the milking cluster in a raised position (normal if the vacuum pump is switched off), the automatic cluster removal is activated by lifting up the cluster. The vacuum in the milking cluster sucks the diaphragm against the contact ring in the bulkhead of the system. The contact ring completes the circuit in the head of the ACR. This contact shuts off the vacuum to the milking cluster removal unit and admits outside air causing the milking cluster to drop. This action starts the vacuum delay and the initial delay.
5.1 Vacuum delay This delay begins when the system is activated (see above) and gives the operator the opportunity to lower the milking cluster and prepare it for connection. During this brief period the milk shut-off valve in the Isolator Xp milk flow sensor remains closed. This delay means that as little excess air as possible is admitted during connection. The delay can be set from 0 to 4.5 seconds. The factory setting is 1.5 seconds
5.2 Initial delay During the initial delay the ACR signal is suppressed to prevent the milking cluster being removed before the milk has started to flow properly. The initial delay factory setting is 120 seconds for cows and 60 seconds for goats. When the initial delay has elapsed the removal system is stand-by. The animal is milked as usual. After a certain time the milk flow decreases until the rate is less than the milk flow time set in the ACR system. Vacuum to the clawpiece is then shut off and the cluster removed automatically.
5.3 Drop-off system This mechanism ensures that the cluster is lifted up immediately by the ACR system if it drops off/ is kicked off during milking. The clawpiece shut-off valve will be closed at the same time. A light flashes on the Isolator Xp milk flow sensor to warn the operator. The drop-off signal is reset if the wash signal is activated. The drop-off signal can be switched off during sampling. During the delay the user must keep the key pressed down for 4 seconds. The large LED will light up. The drop-off signal will be sensed again after the Isolator Xp milk flow sensor has been set to the wash position.
5.4 Drop-off delay If the milking cluster has fallen off/ been kicked off during milking the removal system will be in drop-off mode. From this mode the operator can connect the milking cluster normally (lift cluster up). This will restart the system with a delay of 20 seconds instead of 120 seconds. If the milk is not flowing within 20 seconds, the milking cluster will be removed.
5.5 Cluster venting delay This is the period between the milk tube valve closing until the moment the automatic cluster removal removes the cluster from the animal. During this time the clawpiece fills up with outside air via the vent hole. This means the teats are gently removed, comfortably lifting the cluster from the animal.
10/03-1.0

D105018
5.6 Milk sweep When the cluster has been lifted by the automatic cluster removal there is usually a certain amount of milk residue left behind in the clawpiece or milk tube. Briefly opening the milk tube shut-off valve (standard setting 15 seconds after removal of the milk cluster ) admits a rush of air which removes the last traces of milk. Set the time using ACR3TOOL. The milk sweep can be switched on or off. It is not used in jar dairies, as in this situation the jars are vented after milking cluster removal so there is no vacuum available to open the milk tube shut-off valve.
5.7 Pulsation When the pulsation function has been activated, pulsation will start as soon as vacuum has been created and milking has started. Standard pulsation setting at milking. ·

The stimulation block time has elapsed (standard setting 30 sec). This time starts as soon as the first milk is sensed.
·
The stimulation time window (the time parameters within which stimulation takes place) must be started (standard setting 70 sec). The milk flow during this period must be less than the set value (standard setting 400 gram / minute)

5.10 Switch operation The Isolator Xp milk flow sensor is easy to operate. The Isolator Xp milk flow sensor has a single switch with the following functions: ·
From stand-by mode (milking cluster lifted, all 3 LEDs lit up) press the switch for 1.5 seconds. This action places the Isolator Xp milk flow sensor in stand-by wash mode: The milking cluster is lowered, but the milk tube shut-off valve remains closed. When the power has been switched off, the valve will open for washing.
·
If the switch is briefly pressed during the stand by wash mode, the Isolator Xp milk flow sensor will return to stand-by milking mode.
·
If the switched is pressed for 1.5 seconds during the milking mode, vacuum to the milking cluster will be shut off. During milking the cluster will be lifted off if the Isolator Xp milk flow sensor is accidentally activated.
·
If the Drop-off/Removal Stand-by LED (35) flashes, press the switch for 1.5 seconds to return the Isolator Xp milk flow sensor to stand-by mode. If the ACR system is then started (after the cluster has been lifted) all wait /delays times are again available.
·
Manual start stimulation (if set). Stimulation will start within the stimulation time window (standard 70 seconds) if the button is pressed.
·
Starting stimulation when the cluster is connected. Press the button to deactivate stimulation for the individual animal.
·
Placing the Isolator Xp milk flow sensor in program mode (service purposes only). Set the sensor to stand-by wash mode. Press the button for 4 seconds until all 5 LEDs light up. Release the button. The Isolator Xp milk flow sensor can now be programmed using a PC and a programming adaptor.
·
Deactivate Drop-off by pressing the button for 4 seconds during milking position. The large LED will switch off.

6.1.3 Positioning the automatic cluster removal Before mounting the automatic cluster removal and TLs establish the milking method used in the parlour concerned. For example, is milking done from the side or from between the hind legs? Correct positioning of the automatic cluster removal is very important to prevent hindering the animal during removal. Install the ACR so that the pulley is aligned with the animal’s udders. Figure 12 shows the automatic cluster removal position if the clawpiece is connected between the animal’s hind legs. If milking is done from the side in a herringbone parlour refer to figure 13. In a tandem milking parlour, position the automatic cluster removal as shown in figure 14. Cut all cables to size with a slack of about 20 cm to allow corrections to be made at a later date. This also applies to the vacuum supply line.

6.1.4 Attaching the cord to the automatic cluster removal Open the protection pin and remove the lower pulley holder. Place the cord around the cord holders as shown in figure 16.
Figure 15: Attaching the cord to the automatic cluster removal
6.1.5 Mounting the automatic cluster removal horizontally If the ACR is to be mounted horizontally, it is advisable to attach the cord guide to the bottom of the ACR. Drill 2 4-mm. holes in the lower CR lid as shown in the drawing below. Mount the cord guide using the screws in the guide kit. Mount the ACR horizontally using 76mm. plastic line clamps D240810 (not included). Mount one at each end of the orange unit.

6.1.6 Mounting the ACR vertically If the ACR is mounted vertically in a dairy with I parlour/ 2 milking positions the removal cord is pulled in two directions. In this kind of situation, we advise replacing the pulley on the underneath of the ACR with a cable guide. See ‘A’ in figure 17.
Figure 17: Attaching the cable guide 6.1.7 Attaching the clawpiece to the automatic cluster removal Figure 18 shows how to attach the clawpiece to the ACR. Estimate the correct length of the cord/extension cord before tightening the clamping ring.

6.2 Mounting the Isolator Xp milk flow sensor Mount the Isolator Xp milk flow sensor as shown in figure 20. The sensor can be mounted vertically or horizontally to the bars of the parlour using a U-bracket/saddle combination. If the “GM-Isolator Xp� logo plate on the side of the Isolator Xp milk flow sensor is switched over, it can be mounted in the opposite position on the other side of the milking parlour. Use 4 self-tappers to
D105018

Unused cable glands must be sealed off watertight.
6.2.2 Sealing the cable glands Apply Locktite® to the thread to prevent water entering i.e. from high-pressure cleaners etc. See ‘A’ in figure 22. Use Locktite® type 542 or similar. Note: After the milk flow sensor has been installed, tighten the thumb nut again under vacuum. This seals the milk chamber tightly.

6.2.3 Mounting on low-line milking installations Figure 23 shows the line connections for low-line milking installations. For the vacuum connection an 8.6 mm hole must be drilled in the vacuum supply line (A) with a 1/8" thread. Screw in a plastic nozzle and connect to the automatic cluster removal using a PVC tube. The length of the PVC tube used to attach the Isolator Xp milk flow sensor to the milk line (C) must be at least 30 cm. to prevent milk causing blockages. Blockages in the milk lines can cause problems for probe detection. The Isolator Xp milk flow sensor works by sensing conductivity. It is therefore important to earth the milk lines correctly.
Figure 23: Mounting low-line milking installations A. Vacuum supply line B. Pulsation line C. Clean air line D. Milk line IMPORTANT - A clean air line must be connected for all low-line milking installations. This prevents moisture entering the drop-off sensor chamber, which would otherwise cause malfunctioning. If the milking installation does not have a line suitable for clean pulsation air, provide separate arrangements.
10/03-1.0
31
D105018
A pulsation silencer line may be used - assuming its diameter is not smaller than the pulsation line. In older installations a clean air line of 63mm diameter or larger can be mounted - if it is not used as a silencer line.
6.2.4 Mounting on high-line milking installations If the Isolator Xp system is mounted in high-line installations, a remote control switch with LED unit is recommended (the usual operation switch will be out of reach due to the sensor’s high position). The remote control switch with LED unit is supplied with a mounting bracket and Ubolt. Mount the switch in an easy to access position. Note: The LED in remote control switch switches synchronous to the removal LED (37 on page 21). A milk tube support is also recommended. Place this at a short distance form the Isolator Xp milk flow sensor. Place the line in the hole in the bracket and join the top to the sensor with a piece of milk tube. Then attach the long milk tube to the lower part of the line (see figure 24).

6.3 Lectron TL pulsator 6.3.1 Mounting The Lectron TL is mounted to the side of the boosting line. In new installations: Drill a Ø17 mm. hole in a 63 or 90 mm PVC booster line and debur the hole before mounting the Lectron TL pulsator (see Figure 25).
Figure 25: Mounting Lectron pulsator onto the lines Centre the pulsator clamp correctly before tightening the bolt. If the clamp is not positioned correctly the booster line may be damaged irreparably. Drill a Ø 25 mm. hole at the side of the booster line and screw in a 3/4" gas thread. Mount a 25 x 3/4" nozzle and place the Lectron TL pulsator on it (see Figure 26). Then mount the pulsator clamp with a screw after the “T” piece has been removed. Note: , A 25mm x 1/2" nozzle can be used with existing installations with booster lines with a smaller diameter and 1/2" galvanized T-pieces
Figure 26: Placing the Lectron TL pulsator using an adapter

D105018
6.3.2 Wiring The Lectron TL pulsator is supplied with a 3-metre 0.5 mm 3-core cable. Use the shrink sleeve insulation case and weld the cable joints. Use conduits for wiring. Preferably connect the Lectron TL pulsators to a silencer line. The connections concerned are on the lower lid of the Lectron TL pulsator. The silencer line not only damps the noise produced by the Lectron TL pulsator, but also supplies it with clean air. The air supply to the lines must be connected outside the dairy in clean surroundings. Note: The diameter of the silencer (clean air) line must never be smaller than the diameter of the booster line.
6.4 Parameters Remove the lid to access the PCB in the Isolator Xp milk flow sensor. The PCB can then be removed from the housing. The following can be set: 路
End milking signal
路
Initial vacuum delay time

Make other settings using ACR3TOOL appendix 2. Note: Ensure the PCB is replaced in the sensor housing before mounting. Note: The type of parlour determines which print in the Isolator Xp milk flow sensor must be used:
6.4.1 Isolator Xp milk flow sensor Type Print D480197 For milking line installations cows D480180X1 D480199 For milking line installations goats with milking cluster retractor D480194x1 D480200 For milking line installations goats hi-line with milking cluster retractor D480195x1 D480201 For milking line installations goats with automatic cluster removal D480202 The times are set using the binary system via the DIP switches. If the PCB is positioned vertically and the large LED pointing upwards, the switch will point downwards in the OFF position (0) and upwards in the ON (1) position.

6.4.2 Milk Sweep (DIP switch 1) This switch has an ON and OFF position. If Milk Sweep is ON, the milk shut-off valve is opened for 15 seconds, after milking cluster removal. This briefly admits air into the clawpiece to remove any milk residue from the clawpiece, milk tube and milk flow sensor. If the switch is in the OFF (0) position there will be no milk sweep. Switch 1 0 1
Milk Sweep OFF ON
6.4.3 Clawpiece shut-off time This is the period of time that vacuum on the clawpiece is shut off until the ACR removes the cluster from the animal’s udder. During this period outside air is admitted to the clawpiece via the vent, and the vacuum level drops. This allows comfortable and gentle removal from the animal. The time can be set from 1 to 4 seconds in 1-second steps. Switch 2 0 0 1 1
Switch 3 0 1 0 1
Vent time in seconds 1 second 2 seconds 3 seconds 4 seconds
6.4.4 Vacuum delay This is the period from the moment the milking cluster is lowered until actual connection of the first teat cup. During this period the milking cluster can be positioned under the udder. The delay time is set correctly if the clawpiece is under vacuum just before connection to the first teat. Switch 4 0 0 1 1
Switch 5 0 1 0 1
Vacuum delay 0 seconds 1,5 seconds 3 seconds 4,5 seconds
6.4.5 End - Milking – Signal This is the set end-milking signal where the milk shut-off valve in the Isolator Xp milk flow sensor is closed causing the cluster to be removed from the udder. The 8 settings vary from 20 to 90 %. The milk/air ratio is a time measurement, expressed in percentages, during which probes sense the presence of milk. Measurement is continuous in a time window of 25 seconds. Example: 50 % detection (milk present between both probes for 50% of the time during a 30 second period) corresponds to a milk flow of 200 gr/minute. The vacuum on the clawpiece is shut off if the probes sense the presence of milk less than 50 % of the set time.
D105018
36
10/03-1.0
Figure 28: Setting end-milking signal Figure 28 shows switches 6, 7 and 8 in the factory settings of resp. 0-1-0. These settings correspond to an end-milking signal of 200 gr/minute. These settings can be fine tuned in the parlour using other milk flow ratios.
6.4.6 Drop-off sensor adjustment Note: Each Isolator Xp milk flow sensor installed must be adjusted as follows to determine the drop-off moment: 1. Switch on the milking installation (check the working vacuum) and set the Isolator Xp milk flow sensor to stand-by. Switch on pulsation if central pulsation is used. Remove the cap (1) from the Isolator Xp milk flow sensor. 2. Unscrew the protection nut and loosen the drop-off setting screw (B, figure 22) until the drop-off sensor no longer works (LED 38 goes out). 3. Mount a vacuum gauge between the long milk tube and the Isolator Xp milk flow sensor milk inlet nozzle using a 14 mm. T-piece and 14 mm. milk tube, length 100 mm. 4. Activate the Isolator Xp milk flow sensor by lifting the milking cluster. 5. Place the milking cluster on the cow standing with the teat cups spread upwards (as if the cluster had fallen off or been kicked off). After the vacuum delay has elapsed outside air will be sucked in via the clawpiece. 6. Read off the vacuum level on the vacuum gauge. This will give a global idea of the vacuum drop that can be expected if the clawpiece falls off the animal. This is the vacuum level with the clawpiece in the parlour. 7. Replace the clawpiece on the long milk tube by a valve, see figure 29. Leave the clawpiece attached to the removal cord. 8. Note the vacuum level on the vacuum gauge, while the valve is closed and the Isolator Xp milk flow sensor activated. This is the working vacuum level. 9. Calculate the adjustment vacuum level for the drop-off sensor as follows: Working vacuum level + vacuum level with clawpiece in parlour 2 10. Adjust the valve at the end of the long milk tube until the vacuum gauge indicates the value calculated at 9.
10/03-1.0
37
D105018
11. Adjust the drop-off screw (B in figure 25) until the drop-off LED lights up. 12. Wait 20 secs. until the milking cluster is in drop-off mode - in other words when the “milking cluster removed” LED flashes. 13. Activate the Isolator Xp milk flow sensor (lift milking cluster), briefly remove the valve at the end of the long milk tube until the air rush in the sensor has pushed the diaphragm valve into the right output position. Connect the valve to the milk tube again. 14. Check the vacuum gauge and adjust using the valve if necessary. 15. Adjust the drop-off screw until the drop-off LED lights up. 16. Repeat steps 10 to 15 to check the settings and adjustments 17. Tighten the locking nut 18. Replace the valve on the long milk tube by the milking cluster.
19. Place the cap on the Isolator Xp milk flow sensor again Figure 29: Replace milk tube by valve 1. Valve 2. Vacuum gauge 3. Setting screw and locking nut
6.4.7 Description drop-off adjustment The diagram below shows the inside of the Isolator Xp milk flow sensor .Drop-off valve C is the upper diaphragm covered by a metal disc, A is the trace contact and B is the Drop-off setting screw, as described in the previous section ‘Drop-off sensor adjustment’. If the cluster falls, the air enters with so much force that the diaphragm is forced upwards causing the metal disc to come into contact with setting screw B. This completes an electrical circuit. After a brief delay time*) the system realises that a cluster has fallen.
D105018
38
10/03-1.0
Note: The brief delay allows the system time to determine if there is any cyclic vacuum fluctuation - which may occur normally during milking.
Figure 30: Drop-off sensor
6.5 Inside of the Isolator Xp milk flow sensor The diagrams below shows a cross section of the Isolator Xp milk flow sensor. The upper figure 30 shows the sensor in stand-by position. The solenoid is activated and open so vacuum is present in the sensor. The lower chamber is under vacuum, which forces the diaphragm and spring downwards. This closes the shut-off valve: The milking cluster is not under vacuum. Note: The vacuum on the drawing is shown in dark grey, the atmospheric air is light grey.

7 Maintenance 7.1 Before each milking Check if all the vent holes in the clawpieces are open. Also check all rubber tubes and connections for leaks. Attention: blockages or leaks obstruct the milk flow, which will have a negative effect on how the sensor determines the milk flow. This may mean that the milk cluster is taken off too early or too late.
7.2 Monthly Lubricate the suction seal and the inside of the automatic cluster removal. Check for general wear and tear. Also see “Demounting the ACR� page 7.2. Only use silicone oil to lubricate the suction seal. NEVER use any other type of oil or grease.
7.3 Annually Check diaphragm quality in the Isolator Xp milk flow sensor and replace if necessary. Also check all seals, chimney ducts and valves for wear and tear. Replace if necessary.
7.4 Every 3 years Replace the diaphragms, seals, chimney ducts and valves on the Isolator Xp milk flow sensor. Also replace diaphragms and seals on the ACR system.
