13.1 HYDRAULIC SYSTEM
13.1.1 GENERAL DESCRIPTION
Automated arm units use an extra valve stack to control the arm (figure 13.2). This valve is aproportional type, meaning that amount of flow coming out of it will be according to the positionof the spool. This feature allows infinite control of the speed and the movement of the arm. Thearm is powered by a piston pump (see section 13.1.2 “Tandem Pump”). For more informationon hydraulic system and the control valve of the body (figure 13.1), refer to both the GeneralMaintenance and the Hydraulic sections. You will find detailed schematics and procedures toservice the valve and/or to identify pipes and hoses.
This section will show how to adjust the hydraulic pressure of the arm and to calibrate cushioningsystem. At the end of the section, you will find a troubleshooting section, which if combined tothe Expert 2000 Troubleshooting section, will help resolve most of the commonly seen problemson that type of unit.
Note:Before servicing an automated arm unit, make sure to have the proper skills and training. Referto section 1.5 “Lockout/Tagout procedure”.
SECURE THE AREA AROUND THEPATH OF THE ARM PRIOR TOPERFORMING ANY REPAIRS ORMAINTENANCE.

13.1.2 TANDEM PUMP
The automated version of the Expert 2000 is equipped with a tandem pump (figure 13.3). Thetandem pump is made of two separate sections: The vane pump and the piston pump withvariable flow.
The vane pump section powers all the body functions such as the tailgate, the body hoist, thepacker and the crusher panel. All these functions are controlled through a directional controlvalve.
The piston pump, however, powers the automated arm functions such as the grabber, the innerand the outer boom for the retraction and extension movement. All these functions are controlledthrough a proportional valve.
Finally, the tandem pump is connected to the engine crankshaft and therefore is always turningwhen the truck engine is running.

THE VANE PUMP SHALL NOT TURNANY FASTER THAN 2300 RPM.
13.1.3 VANE PUMP
Since the pump is connected directly to theengine, it is constantly turning and pumpinghydraulic oil. In order to control the hydraulicflow, a dump valve mounted on the pump(figure 13.4) is either used to send the fluid tothe body hydraulic system or sent back to thetank.
When the pump switch (figure 13.5) is turned“ON”, an electric signal is sent to the dumpvalve solenoid. Then, the flow of the vanepump is sent to the body directional valve.Otherwise, when the pump switch is turned“OFF , the hydraulic flow returns back to thetank.
When the switch is turned “ON”, thetransmission electronic control unit (ECU),monitors the vehicle speed and the engineRPM and then allows (or not) the dump valveto engage. If the vehicle is exceeding 15Mph(25Km/h), or if the engine speed exceeds900RPM, the dump valve will not engage.
A minimum of 90 PSI of air pressure is alsorequired for the dump valve to operate. Thisminimum pressure ensures that the hydraulictank will be pressurized before using the pump.
After the dump valve is engaged, it will stayengaged at any engine speed under 2300 RPM.Refer to section 13.3.3 “Allison TransmissionProgramming Parameters”.
The vane pump is capable of delivering a flowof 40 gallons per minute when the engine isrunning at 1200 RPM.
A flow regulator at the pump outlet (figure 13.4)limits the flow to the directional valve. Anyexcess flow above 50GPM is sent back directlyto the hydraulic tank. When the dump valve isnot engaged the flow returns to the tank.

WARNING
13.1.4 PISTON PUMP
This section of the tandem pump is equippedwith a load sensing system. This means thatthe pump will deliver its flow according todemand.
When moving the joystick, an electric signalfrom the joystick is sent to the coils on theproportional valve (figure 13.6), allowing thespools inside the valve to move accordinglyand proportionally to the movement of thejoystick. The demand or “load” is then created.
At that point, the piston pump starts to deliverits flow to the proportional valve making thearm to move.
The pump will deliver its flow proportionallyto the demand (or movement of the joystick).When there is no “load”, (Joystick to centerposition) the pump turns without sending oilin the system (Refer to section 13.2.2 “Pistonpump adjustment”.
In order to operate the arm and send a signal tothe proportional valve, the pump switch mustbe turned “ON” and the joystick moved outfrom its center position.

WARNING
13.1.5 PRESSURIZED TANK
To ensure proper fluid supply to the pump andto prevent cavitation in the hydraulic system,air pressure of 3 to 3.5 PSI is applied to thehydraulic tank. The cavitation is defined as theformation of air pockets in a moving fluid. Thepresence of air in the hydraulic oil producescavitation inside the pump, generatingexcessive noise. Cavitation is forming most ofthe time after replacing hydraulic componentsor after flushing the hydraulic system.
A gage and a pressure regulator are installed toadjust the air pressure inside the tank. Thisgage is located inside the frame rail on thecurbside of the chassis (figure 13.8). This gagecan be accessed only when body is raised.
The hydraulic tank is also mounted with a5-PSI relief valve (figure 13.9) and a 5-PSIpressurized filler cap.
INSTALL THE BODY SAFETY PROPBEFORE PERFORMING ANY WORKUNDER BODY.

13.2.2 PISTON PUMP ADJUSTMENT
As described in section 13.1.3, the pistonpump delivers its flow only on demand (whenthe joystick is moved). The compensator,located on the pump (figure 13.22), controlsboth the pressure output and the load sensingsystem of the piston pump.
How it works:
The load sense port on the proportional valveor LS port (figure 13.21), allows pressurefrom the valve to return to the compensator,creating a margin pressure of 450 PSI betweenthe PP port and the LS port. When moving thejoystick, the pressure on the LS port will buildup, creating the demand to the piston pump.
At that point, the compensator will increasethe pump flow, keeping the pressure 450 PSIabove the pressure of the load sense port.
If a pressure of 2000 PSI is required to lift acart, the pressure at the PP port will be 2450PSI. A differential pressure of 450 PSI. Whenthere is no demand, the pressure at the port LSwill drop to 0 PSI.
Note:The port PP should always indicate 450 PSI.
The pressure adjustments of the pumpcompensator and the proportional valve haveto be made, following the right sequence.
Two pressure gages (0-4000) are necessary toperform this adjustment. One connected to thepressure port (PP) and the other on the loadsense port (LS). See figure 13.23.
The procedure on the next page will show howto adjust the load sense and the pump maximumoutput pressure.

13.2.7 CYLINDER CUSHION ADJUSTMENT(cont’d)
Proximity switches detect the presence ofmetal. When metal is detected, the red pilotlight on the proximity switches turns “OFF”and the arm starts to slow down.
The first red light that shuts off marks thebeginning of a cushion. (A red light on eachproximity switches corresponds to “no cushionsignal”). Therefore, the arm is moving fasterwhen the red lights are “ON”.
The position of each proximity switch on themounting brackets will determine where thecushioning will start. Two pairs of proximity
switches are required to control the cushioningsystem of the arm. Each pair controls eitherthe retract or the extend cushion of a cylinder.
To adjust the proximity switches werecommend to use the following procedure:

13.2.7 CYLINDER CUSHION ADJUSTMENT(cont’d)
Located inside the console, two electronicmodules control the speed or amount of cushionfor the outer and the inner boom cylinders. Oneach module, there are screws for cushionspeed adjustment (figure 13.34). It is notrecommended to change the adjustment ofthe cushions since they were adjusted at thefactory.
However, if the arm does not reach or hits therubber bumper too hard, it is possible to reduce(or increase) the speed of the cylinder cushion.Perform the following procedure for cushionadjustment:
CUSHION SPEEDADJUSTMENT PROCEDURE
1. Secure the area around the path of thearm.
2. Start the engine and engage thehydraulic system.
3. Clearly identify the cylinder cushionthat needs to be adjusted and thecorresponding module.
4. Move the joystick slowly to the desiredposition in order to bring the cylinderat the beginning of the cushion range(distance Dx), At that point, the redpilot light shall turn “OFF”.
5. Release the joystick and make surethat the proximity switch light is “OFF”.
6. Move the joystick again in the samedirection to evaluate the speed of thearm. The arm cylinder should reachthe end of its stroke without knocking.If not, increase the amount of cushion(reduce the speed).
NOTE:The word “extension” and “retraction” referonly to the cylinder movement and not themovement of the arm itself.

DANGER
DO NOT STAND DIRECTLY IN THEPATH OF THE ARM WHILECARRYING OUT THESEADJUSTMENTS.
APPLY THE “LOCKOUT/TAGOUT”PROCEDURE AT ALL TIMES.
The screw on the cushion module may beturned clockwise or counterclockwisedepending on what result is required.
The cushion’s speed adjustment is made bystep of one quarter (1/4) of a turn at a time. Seefigure 13.34 for proper way to increase ordecrease the amount of cushion as it is not thesame way for each screw).
Increasing the amount of cushion will result inreducing the speed of the arm in the cushionrange. Decreasing the amount of cushion willresult in faster arm speed in the cushion range.

13.2.8 ARM SPEED ADJUSTMENT
The arm speed is controlled by the amount ofhydraulic fluid that is being sent to the arm’scylinder. The arm control valve spools can letthrough 6 to 10 gallons per minute of hydraulicoil, depending on the section of the valve*.The flow is limited by a mechanical movementrestrictor or stopper (figure 13.36).
Note:No arm speed adjustment is required unlessreplacing the valve or a section of it.

ARM SPEEDADJUSTMENT PROCEDURE
1. Secure the area around the path of thearm.
2. Start the engine and engage thehydraulic system.
3. Clearly identify the stopper screw onthe valve that corresponds to theproper function (boom extension/retraction, grabber open/close). Movethe lever to evaluate the speed of thearm then release the lever.
4. Loosen the lock nut.
5. Screw in the restrictor adjustment onlyone eighth (1/8th) of a turn at a time tosee a significant change of the arm’sspeed.
6. Move the lever again to evaluate thearm’s speed. Repeat until satisfactory.
7. Tighten the lock nut.
NOTE:The cushioning system is not functioning whenusing manual control levers.
* Limiting the stroke of the spools is limitingthe amount of oil (flow) going through them.Controlling the flow of oil means controllingthe speed of the arm.

13.2.9 OUTER BOOM RESTRICTORADJUSTMENT
The outer boom cylinder is equipped with anadjustable restrictor on the rod side (extension).The restrictor (figure 13.37) prevents theweight of the arm to pull the cylinder fasterthan the oil pressure.
RESTRICTOR ADJUSTMENTPROCEDURE
1. Secure the area around the path of thearm.
2. Engine at idle speed: 750-800 RPM.
3. Maintain the crusher panel up to warmup the hydraulic oil (10-15 minutes).Release the crusher panel thenactivate the packer blade so the oilgoes through the whole system.Repeat this operation until the oiltemperature reaches 150 0F.
4. Position the arm as shown in figure13.38.
5. Unlock the restrictor knob byloosening the hex key lock screw.
6. Screw-out the restrictor knob.
7. Extend and retract the outer boomseveral times. At one point, whileextending the outer boom, the weightof the outer pulls faster on the cylinderthan the flow coming from the pump.The arm slows down and goes againwhen the flow reaches the cylinder.
8. Screw-in the restrictor until the pumpalone forces the extension of thecylinder and you obtain a steadypendulum motion.
9. Do not over screw the restrictor, sincethe restriction has to be at theminimum, so the arm speed and the oiltemperature are not affected.
10. Once properly adjusted, lock therestrictor knob in place using the hexkey lock screw.

INNER BOOM LOCK VALVEADJUSTMENT PROCEDURE
1. Secure the area around the path of thearm.
2. Start the engine and engage thehydraulic system.
3. Operate the inner boom to ensure noair is in the hydraulic system.
4. Retract the inner boom cylinder toone-third of its stroke (Inner boomdown), then extend the outer boomcylinder to full reach.
5. Loosen the locknut on the cartridge ofthe lock valve (figure 13.39).
6. With the pump switch turned off,tighten the adjustment screw until theinner boom starts to fall under it’s ownweight (The inner boom may start toshake when loosening too much).
7. Then return the screw back in until theinner boom just stops falling. Pick upa weight of 450 lbs to the grabber andcheck if the inner boom goes furtherdown. If the inner boom falls, loosenthe adjustment screw until it stops.
8. Once properly adjusted tighten thelocknut of the adjustment screw.

13.2.11 GRABBER LOCK VALVEADJUSTMENT
The purpose of this lock valve is to lock the oilinside the cylinder so no oil can come out oneither side of it. This situation will remainuntil enough flow or pressure is sent in againto move the cylinder.
This feature ensures that once the grabber isclosed on a roller cart, it will remain that wayand will not close any further or open untilanother hydraulic signal (like open or closethe grabber) is sent. No maintenance oradjustment is required on the lock valve.
In case the grabber fails to hold onto carts,remove and clean the valve or replace it

13.2.12 PRESSURIZED HYDRAULIC TANK
To make sure the pump is properly fed with oiland to prevent any cavitation, the hydraulictank is pressurized with air.
The air from the brake system of the truck isbeing used for this purpose. The pressure hasto be brought down around 3 to 3.5 PSI withthe use of an air pressure regulator(figure13.44).
Then the air pressure enters the hydraulic tankfrom the top and presses down on the hydraulicoil to feed the pump. To prevent any pressurebuilt up, a safety relief valve set to PSI is beingused. The filler cap will also vent any airpressure higher than 5 PSI.

13.3.1 ELECTRICAL SYSTEM GENERALDESCRIPTION
The automated side loader units use the sameelectrical system for the body and cab controlsas the standard Expert 2000 unit, except thewiring of the auto-neutral system(See section 13.3.4).
Also, the automated arm has a separate wiringsystem. A combination of different color-codedwiring harnesses, ensure the proper electricalcommunication between the joystick, the armcomputer (cushioning module) and thehydraulic control valve.
Most of the electrical components are locatedin the console. A sealed packer control modulelocated at the front of the body and can beaccessed through a removable access door(figure 13.45).

13.3.3 ALLISON TRANSMISSIONPROGRAMMING PARAMETERS
The Allison transmission electronic controlunit (ECU) controls several systems of theautomated unit; it prevents pump from overspeeding (2300 RPM maximum). The ECUalso prevents the pump engagement if theengine speed is any higher than 900 RPM. Itwill also shut off the pump and the joystick (ofthe arm) if the vehicle is moving faster than15 MPH (25Km/h). The transmission ECUalso controls the auto-neutral system.
If the vehicle requires having the ECU repairedor replaced, or a specific programmingparameters, refer to section 3.17 “AllisonTransmission Programming Parameters”.
A “Pro-link” keypad interface (figure 13.47)may be used to program the Allison ECU andverify if the signals are properly reaching thecomputer and verify the fault code. To tap ontothe ECU, Labrie uses the following wires onthe Allison connector:
INPUT:
#117: PUMP PACK ENABLE: Active whenthe brakes are used, and when the PTOand auto-neutral switch is“ON”(ground signal).
#118: PTO ENABLE: Active when the PTOswitch is “ON”(+12V. signal).
#153: AUTO-NEUTRAL PACK INPUT:Active when the brakes are used, andwhen the PTO and auto-neutral switchesare “ON” (ground signal).
OUTPUT:
#112: PTO ENABLE OUTPUT: Active whenthe PTO switch is “ON” and when allengine and vehicle speed criteria arerespected (+12V. signal). Refer to theprogramming parameter chart,section 3.17 “Allison TransmissionProgramming Parameters” in theTroubleshooting section of the Partsand Service manual.
#114: NEUTRAL SIGNAL OUTPUT: Activewhen the transmission is in neutral. Thissignal (ground signal) is used to allowthe fast idle engagement (1500 RPM).For more details, refer to the electricalschematic.
FIGURE 13.47
13-33
COOL HAND AUTOMATED ARM
13.3.4 AUTO-NEUTRAL SYSTEM
The Auto-neutral switch allows thetransmission to shift from “DRIVE” to“NEUTRAL” automatically without using theshifter lever or shifter keypad.
When the operator stops the vehicle and appliesthe temporary handbrake, a signal is sent totransmission computer (ECU) to automaticallyshift the transmission to “NEUTRAL”.However, the transmission will not shift backto “DRIVE” automatically when releasing thetemporary handbrake; the operator must pressthe footbrake pedal to shift back to “DRIVE”
Also, when the Auto-neutral switch is set to“ON”, the transmission will automatically shiftto NEUTRAL as soon as the operator pressesthe footbrake pedal (without activating thetemporary handbrake).
30 PSI of air is required at the brake pedal toactivate the Auto-neutral. This means that amedium pressure of the foot on the brake pedalis sufficient to activate the Auto-neutral andshift the transmission to “NEUTRAL”. Whenreleasing the brake pedal, the transmissionwill shift back to “DRIVE” automatically.
FIGURE 13.49
FOOTBRAKEPRESSURE SWITCH
Pressure switches (figure 13.48) are installedon the footbrake pedals. The one installed onthe right-hand side, is found in the cab behindthe pedal (figure 13.49). The one on the left-hand side is accessible from the enginecompartment mounted on the firewall(figure 13.50). A third pressure switch islocated behind the temporary handbrake toggleswitch (figure 13.51).
