It is imperative that personnel involved in the installation, service, and operation of the Oildyne units be familiar with how the equipment is to be used. They should be aware of the limitations of the system and its component parts, and have knowledge of good hydraulic practices in terms of safety, installation, and maintenance.

Explanation of Warning LabelsThe following labels will be used in this Instruction Manual and on all applicable Oildyne products.

DescriptionThe 550 Series Hydraulic Power Unit consists of an AC electric motor, fixed displacement gear pump, relief valve and reservoir with options for different circuit types incorporating NG6/D03 valves or 2 position/2 way cartridge valves. The gear pump is driven through a coupling located between the electric motor drive shaft and the pump drive shaft.

For dimensional drawings please see pages 4 to 6.

Two basic versions are available, either with SAE-6 (9/16-18) ports for the P and T connections, or with JIC-6 male extension tube fittings for use with the NG6/D03 version of the adapter.

For hydraulic schematics, please see pages 7 and 8.

The life expectancy of Parker Oildyne power units is directly tied to the frequency of use, the product in which it is incorporated and the application.

Shipping weights for the 550 Series Power Units range from 14.5 kg (36 lbs) to 50 kg (110 lbs).

The 550 Series Power Units are intended to be used in a variety of applications, specified by the customer, where pressurized hydraulic fluid is needed to move an actuator(s), charge an accumulator(s) or supply test equipment.

Pressure Capability (depends on pump/motor combination):• Upto207bar(3000psi)maximum

Flow Output (depends on pump/motor combination):• At1725rpm:.95–5.6lpm(.25–1.5gpm)• At3450rpm:1.9–11.4lpm(.5–3gpm)

550 Series Power Units should be installed indoors in a clean environment.

550 Series Power Units are designed for a continuous duty. However, do not operate the power unit with pump flow going over the relief valve for any length of time; this creates excessive heat. It is recommended that for any applications requiring a maintained pressure, a circuit be selected which incorporates a load holding check valve(s). Examples of these circuits would be the D1, using the Manapak double pilot operated check valves, or a two position/two way cartridge valve with included check valve.

There may be hydraulic liquid under pressure. Do not open unit or break pipe connections until hydraulic pressure has

been released.

Be careful; take precautions; examine instructions before operation.

Parker Hannifin Corporation takes no responsibility for safety of any unit if it is not used for the intended purposes detailed in this Instruction Manual.

Preparation for Use

Unpacking and Checking All units were carefully packed, in containers or boxes, and may or may not be on skids. In any case, do not remove anything from the skid or any packaging until it has been carefully checked for damage that may have occurred in transit. Report all damage immediately to the carrier and send a copy to the vendor.

All open ports on the power unit were plugged at the factory to prevent the entry of contamination. These plugs must not be removed until just before piping connections are made to the unit.

Storage If the unit is not going to be installed immediately, it should be stored indoors, covered with waterproof sheet, and all open ports kept plugged. If long term storage is expected (6 months or more) we recommend filling the reservoir completely with clean hydraulic fluid to prevent the entry of moisture.

Removing from packagingThe mass of 550 Series Power Units is unequally distributed in the assembly. The electric motors are the ‘heavy ends’ of the power units with the standard motors alone weighing between 8.3 kg (18.2 lbs) and 22 kg (48.4 lbs). It is strongly recommended that two people carry and move these power units. The exception is the 550 Series Power Unit using the 19 liter (5 gallon) rectangular steel reservoir. These are assembled with the electric motor above the reservoir. 550 Series Power Units with the 19 liter (5 gallon) rectangular steel reservoir should be removed from the skid by wrapping a heavy duty nylon strap around the base of the motor mounting feet. This strap should be firmly secured to the lift truck forks when unit is lifted.

Installation

Locating Power Unit The unit should preferably be installed indoors in a clean, dry environment with an ambient temperature of 15 to 38°C (60 to 100°F).

Parker Oildyne products should not be installed where they are at risk of objects falling from overhead or where there is any risk of impact with external objects.

Mounting the power unitThe majority of 550 Series Power Units are complete assemblies. A small portion is created without the electric motors, allowing the customer to purchase and install alternate motors. There is a ‘C-face’ kit available, Oildyne part number 775679, which allows a standard ‘56C with base’ motor to be mounted to the 550 Series. This kit includes a spacer plate, shaftadapterwithsetscrew,threadedstudsandnuts–allthecomponents needed to mount the motor to the power unit. See the Appendix on page 18 for installation instructions using this C face kit.

550 Series Power Units are assembled for mounting horizontally (ports or D03 valve facing UP) or vertically (motor above the reservoir), except for power units using the 19 liter (5 gallon) reservoir, which are designed only for vertical installation (motor above the reservoir).

For port locations see pages 4 - 6.

Mount the power unit securely through the provided slots in the motor foot. See page 4 for the motor foot details. Power units with the 19 liter (5 gallon) reservoir will use the reservoir base flanges to mount to the customer determined location. See page 6 for reservoir mounting flange details. Mounting bolt torque values will be determined by the type of fastener selected by the customer. It is strongly recommended that the surface to which the power unit is mounted is bonded to earth to provide proper grounding in the event of a lightning strike.

Electrical Service Connections Connect the motor to the power source following good practices as outlined in the national electric codes and any local codes which may apply. Verify that the available voltage is the same as the voltage identified on the label. Most AC motors have dual voltage ratings, so verify that the leads in the conduit box have been connected together as defined on the motor nameplate to match the facility power source available. Ensure the wiring connections will provide clockwise motor rotation, when looking at the fan end.

Customer supplied controls will include motor starters and valve operators (for NG6/D03 and solenoid cartridge valves).

Supply and Return Connections 550 Series Power Units incorporating an NG6/D03 valve surface, regardless of the valve being supplied by Oildyne or not, will include two JIC-6 (9/16-18) extensions fittings onto which the A and B actuator control connections can be made. Power units incorporating the P and T ports have two SAE-6 (9/16-18) female o-ring type ports to accept customer fittings.


10

Bulletin HY22-3220A/US Instruction Manual550 Series Hydraulic Power UnitsStart-Up Procedures

In circuits types using solenoid cartridge valves, the T ports will be blocked by Oildyne with an SAE-6 plug.

Fluid connectors and conductors installed by the customer should be selected based on an acceptable safety margin for the maximum pressure required in the application. 550 Series Power Units are capable of producing up to 207 bar (3000 psi).

Complete all necessary interconnecting piping to the power unit. The line sizes should be determined based on oil flow, operating pressure and allowable pressure drop between the power unit and actuator.

One of the key ingredients for good service and long life from a hydraulic system is cleanliness. Because most dirt infiltrates a hydraulic system during installation, we recommend the following:

a) All open ports on the power unit, cylinders, etc. must remain plugged with tape or plastic plugs until just before the hydraulic connections are made.

b) All interconnecting tubing, pipe, or hose should be clean, and free of rust, scale and dirt. The ends of all connectors should be plugged until just before they are to be installed in the system.

c) All openings in the reservoir such as the filler breather or access end covers holes must remain closed during installation.

Hydraulic Fluids Follow all vendor-supplied instructions for safe handling, use and disposal of the fluid selected for operation in this power unit.

It is strongly recommended that the customer have available the MSDS for the fluid chosen for use in the 550 Series Power Unit. Follow all instructions should the fluid be spilled or come in contact with an operator.

It is critical that the reservoir be filled with an approved fluid prior to startup of the power unit. Any system failures due to improper fluids being used or operating without the reservoir being full of an approved fluid will result in voiding the warranty.

The reservoir must be filled with clean fluid through the filler cap on the reservoir. The type of fluid must be compatible with the seals used on the power unit, and must comply with the recommendations of the manufacturers of the component parts. Acceptable fluids include standard Automatic Transmission Fluid (ATF) and most mineral based hydraulic fluids with viscosities between 32 cSt (150 SSU) and 64 cSt (300 SSU) at 38°C (100°F). For fluids other than these, please contact Oildyne Division with the details. If users wish to use alternative oil, hydraulic fluid or ATF, they are warned to check that they have the same properties as those recommended. Parker Oildyne takes no responsibility if alternatives are used.

Reservoir Filling The cylindrical steel reservoirs have filler/breathers with a 3/8-18 NPT thread. The head of the breather is circular allowing the breathertoberemovedandinstalledbyhandonly–notoolsare necessary. The 19 liter (5 gallon) reservoir breather is also operablebyhand–notoolsarenecessary.

The rectangular plastic reservoirs have a filler breather which isa‘pushin/pullout’design,installablebyhand–notoolsarerequired.

Reservoir volumes: Maximum fill at 7 mm (.25 in) below filler for all (vertical and horizontal) but 19 liter (5 gallon) reservoir, which is 25.4 mm (1 in) below filler.

The cleanliness of the fluid going into the reservoir is very important. In some cases, even new oil out of the drum is not adequate. We recommend that any fluid being transferred into the reservoir be done with the transfer pump with a 10 micron filter installed. A Parker-manufactured filter cart is available for this purpose.

Start-Up Procedures

SA or SW circuitsPower units with circuit ‘SA’ or ‘SW’ have two ports, marked P and T. Ports are SAE-6 (9/16-18). With the reservoir filled, jog the electric motor to produce flow from the P port. If no oil shows ensure the rotation is correct (clockwise from motor fan end) and the reservoir is full of oil. Once oil shows, proceed with connecting the power unit to your circuit for operation.

S(1-8) or P(1-8) circuitsPower units with circuits ‘S(1-8)’ or ‘P(1-8)’ have two ports, marked P and T, but the T port is plugged at the factory. Ports are SAE-6 (9/16-18). With the reservoir filled, jog the electric motor to produce flow from the P port. If no oil shows ensure the rotation is correct (clockwise from motor fan end) and the reservoir is full of oil. If the solenoid valve is normally open, energize the solenoid to close the valve. If the solenoid valve is normally closed, ensure the valve is not energized. Once oil shows at the P port, proceed with connecting the power unit to your circuit for operation.

D0 or D1 circuitsPowerunitswithcircuitsD0orD1havetwoJIC–6maleextension fittings for outlet ports, one on each side of the power unit located just behind the NG6/D03 valve(s). Connect the NG6/D03 valve solenoid(s) using the input voltage specified on the valve cover and energize one solenoid. With the reservoir filled, jog the electric motor and oil should appear at one of the JIC-6 male extension fittings. If oil does not appear, check that the valve is energized and also that the motor rotation is clockwise looking at the fan end of the motor. Once oil appears, proceed with connecting the power unit to your circuit for operation.

550 Series Power Units are factory assembled and tested at the pressure setting given in the ordering model code. Should slight adjustments be required, a 3/16 in Allen wrench is needed to turn the relief valve screw, after loosening the 11/16 in lock nut. To increase pressure turn the relief valve screw clockwise (when facing the relief valve). Adjustments are approximately 59 bar (850 psi) per full turn of the screw. When adjustment is complete, retighten the lock nut to 13.5 to 19 Nm (10-14 ft-lbs) torque.

Functional testing is considered complete when the 550 Series Power Unit successfully extends and/or retracts the system actuator(s).

Additional TestingIf required, any tests for radiated and conducted emissions should be performed in accordance with the Electromagnetic Compatibility (EMC) Generic Emissions standards for

environments appropriate to the end use product to confirm compliance with the EMC Directive.

If required, any tests for radiated and conducted immunity should be performed in accordance with the Electromagnetic Compatibility (EMC) Generic Immunity standards for environments appropriate to the end use product to confirm compliance with the EMC Directive.

The standard 60 Hz motors used in the 550 Series Power Units are not certified per the Low Voltage Directive. However, motors which are selected specifically for use in the European Union will meet the Low Voltage Directive.

Special Tools All normal service and maintenance on standard 550 Series Power Units can be accomplished with standard hand tools. No special tools are required.

Safe Operating ProceduresShould a failure of the electrical power supply occur, power should not be returned to these power units without a conscious action by the operator.

550 Series Power Units, when operating with a motor speed of 3450 rpm, will most likely generate noise in excess of 70 dBA but below 80 dBA. When working around this noise level it is recommended that appropriate hearing protection be worn.

550 Series Power Units, when operating with a motor speed of 1725 rpm, will likely generate a noise level in the 65 dBA range.

If noise levels should exceed 80 dBA, it is necessary to take measures to reduce noise. This is normally achieved by placing the power unit/machinery in an acoustically lined enclosure.

Standard 550 Series Power Units include AC motors from 370 W (.50 HP) to 2.2 kW (3 HP) in voltages of 115/208-230 and 230/460 VAC at 60 Hz. Using voltages other than those specified on the electric motor nameplate may reduce the life expectancy and the safety of these units cannot be guaranteed.

Directional control valves and solenoid cartridge valves are voltage specific and must be operated at the voltage stated on the nameplates or coils.

Standard operating temperature range is -7 to +60°C (+20 to +140°F).

550 Series Power Units are designed for continuous duty. However, do not operate the power unit with pump flow going over the relief valve for any length of time; this creates excessive heat. It is recommended that for any applications requiring a maintained pressure, a circuit be selected which incorporates a load holding check valve(s). Examples of these circuits would be the D1, using the Manapak double pilot operated check valves, or a two position/two way cartridge valve with included check valve. Should an operating condition cause the oil temperature to reach the maximum safe temperature of the selected hydraulic fluid, it is required that the duty cycle be modified or external cooling be used, such as a fan circulating air around the reservoir. Under no circumstances should the system fluid ever exceed the maximum recommended temperature of 60°C (140°F).

Bulletin HY22-3220A/US Instruction Manual550 Series Hydraulic Power UnitsOperation and Maintenance

Removal from service

There may be hydraulic liquid under pressure. Do not open unit or break pipe connections until hydraulic pressure has

been released.

If, for some reason, the power unit must be removed from service, follow these instructions:1) Wear protective eye gear.2) Remove electrical power from the motor and solenoid valve

(if applicable).3) Mechanically hold/block the actuator load to prevent its

movement once pressure is relieved in the fluid conductors.4) Only after the load is mechanically held in place, put a

rag around the A or B port fitting and loosen the port connection. The rag will absorb an oil leakage as any locked pressure is relieved. Then put a rag around the other port connection and loosen the port connection.

5) Immediately cap the fluid conductor ends and the power unit ports to prevent the introduction of contaminants until the power unit is reconnected.

6) When reinstalling the power unit, follow all the procedures and startup instructions on page 10.

Operation Suitable lighting requirements for operation of this unit are the responsibility of installing manufacturer.

The 550 Series Power Units are assembled and tested according to the specific model codes ordered. See page 15 for performance graphs which provide the expected flows of the available pump sizes at 1725 RPM and 3450 RPM at a variety of pressures.

MaintenanceMaintenance should only be conducted when units are disconnected from the power supply, depressurized and removed from service.

Reservoirs -Maintain oil level at all times. The oil should be checked after the first 100 hours and verified that the class of oil meets the requirements of the pump being used. Change the oil every 1000 to 2000 hours depending on the application and operation environment.

Cylindrical Steel and Composite ReservoirsTo remove the fluid from the cylindrical steel and composite reservoirs, it is recommended to remove the filler cap and use a siphon to remove the oil. Dispose of, or recycle the used fluid according to local regulations. Once the fluid is removed, an examination of the suction strainer is suggested. To access the strainer, the reservoir must be removed. To remove the cylindrical steel and composite plastic reservoirs, loosen and remove the four screws holding the reservoir flange to the power unit adapter. These screws require an 8 mm (5/16 in) wrench or socket.

In horizontal applications, place absorbent paper or towels under the reservoir flange area to catch any remaining fluid as the reservoir is removed from the power unit adapter. Dispose of any oil-soaked materials according to local regulations.

19 liter (5 gallon) reservoirTo remove the fluid from this reservoir, there are two drain plugs provided, one on each end. These plugs require an adjustable wrench or 15 mm (9/16 in) open end wrench to remove (and replace). Another option is to remove the electric motor and adapter assembly from the reservoir by removing the four each 5/16 in hex head screws holding the adapter to the reservoir cover. Use a siphon to remove the fluid from this reservoir. Dispose of, or recycle the used fluid according to local regulations. This method will allow for examination of the suction strainer.

Suctionstrainer–Itisrecommendedthatatthesameintervalsat which the reservoir fluid is changed, the suction strainer be examined for any conditions restricting the free flow of fluid through it. If the strainer appears restricted at all, it is recommended that the strainer be replaced. The strainer is Oildyne part number 410542. The strainer is hand threaded onto a plastic elbow. Turn the strainer counter-clockwise to remove then install a new strainer by turning the strainer clockwise onto the elbow threads until it is tight against the elbow hex.

Cylindrical Steel and Composite ReservoirsOnce the suction strainer has been installed, replace the reservoir using the same four hex head screws. Ensure the filler port on the reservoir is oriented to face UP. Torque the

are warned to check that they have the same properties as those recommended. Parker Oildyne takes no responsibility if alternatives are used.

Maintenance Suggestions1. Never return to the system any fluid which has leaked out.2. Always keep the supply of fresh fluid covered tightly.3. Use clean containers, hoses, and funnels when filling the

reservoir. Use of a filter cart when adding oil is highly recommended.

4. Use common sense precautions to prevent entry of dirt into components which have been temporarily removed from the circuit.

5. Make sure that the breather/filler on the reservoir is properly fastened.

6. Do not run the system unless the normally provided suction strainer is in place.

7. Make certain that the fluid used in the system is of a type recommended by Parker Oildyne.

8. Parker offers an oil sampling kit which can be used to ascertain the condition of the system fluid.

Maintaining Proper Oil Temperature Hot oil in your equipment’s hydraulic system is one of the primary causes of poor operation, component failure and downtime. Here are some tips on maintaining proper oil temperature.

1. The oil in your hydraulic system was designed for operation within a specified temperature range. You may be able to run it at hotter temperatures for short periods of time, intermittently, without adverse effects. If run continuously with oil that is too hot, equipment will operate poorly causing key component failure and machine downtime.

2. “Hot oil” is a relative term. In most cases, 49°C (120°F) at the reservoir is considered an ideal operating temperature. Always take an oil temperature reading at the reservoir, not at a component or any of the piping.

3. Keep your equipment clean. A thick layer of dirt acts as insulation. It will prevent the hydraulic system from getting rid of heat.

4. On hot days, and in hot climates, check and change the oil more frequently. Be sure to use an oil recommended for hot weather operation by the equipment manufacturer or oil supplier.

Measuring Oil Temperature If your machine does not have a reservoir thermometer, use the “palm test”. First check the tank with your fingertip; if it is not too hot to touch, place your palm on the tank. You should be able to hold it there without discomfort if the oil temperature is about 54°C (130°F) or below.

Isolating Trouble-Spots To determine which components are “running hot” and overheating the oil, touch the outlet fittings and lines at the valves, pumps and motors. If the oil temperature is normal going into a component but hot coming out, that could be one of the potential problem areas.

A sticking valve can cause excessive heat. If a spool does not return promptly to the neutral position, the pump flow will be dumping continuously. This builds up heat rapidly.

If a relief valve is set too low, part of the oil will be dumped across the valve with every cycle. This too, generates excessive heat. Even when all valves are set properly, they may not be

four screws to 5.6 Nm (50 in-lbs). Refill the reservoir with an approved fluid prior to startup of the power unit. Any system failures due to improper fluids being used or operating without the reservoir being full of an approved fluid will result in voiding the warranty.

19 liter (5 gallon) reservoirOnce the suction strainer has been installed, remount the motor and pump combination on the reservoir cover, ensuring the reservoir gasket is still in place, positioned so the four holes on the corners are aligned with the four adapter mounting screw holes. Torque these four screws to 5.6 Nm (50 in-lbs). Refill the reservoir with an approved fluid prior to startup of the power unit. Any system failures due to improper fluids being used or operating without the reservoir being full of an approved fluid will result in voiding the warranty.

The reservoir must be filled with clean fluid through the filler cap on the reservoir. The type of fluid must be compatible with the seals used on the power unit, and must comply with the recommendations of the manufacturers of the component parts. Acceptable fluids include standard Automatic Transmission Fluid (ATF) and most mineral based hydraulic fluids with viscosities between 32 cSt (150 SSU) and 64 cSt (300 SSU) at 38°C (100°F). For fluids other than these, contact Parker Oildyne with the details. If users wish to use alternative oil, hydraulic fluid or ATF, they are warned to check that they have the same properties as those recommended. Parker Oildyne takes no responsibility if alternatives are used.

operating well because of worn orifices or seals. Always remove and check the hot components first.

Check Oil Samples Periodically Periodically checking oil temperature and siphoning an oil sample from the reservoir, comparing it with a sample of new, clean oil, is good preventive maintenance.

Oil that has been running too hot will look darker and feel thinner than new oil. It will also smell burned. Normally it will contain more contaminants, because hot oil leads to accelerated wear of component parts.

using Customer-supplied Motor

Installing customer-supplied motor using 56C Adapter KitThis is easiest with the 550 Series Power Unit sitting vertically on a table with the reservoir down.1. Tighten the tapered ends of the four studs into the motor face threaded holes until bottomed out. These are interference fit studs so resistance is expected.2. Install the shaft adapter onto the motor’s keyed shaft with the set screw positioned over the keyway. With the shaft adapter pushed all the way onto the motor shaft, tighten the set screw to 3.4 to 4.5 Nm (30 to 40 in-lbs) torque using a 5/64 in Allen wrench. 3. Take the coupling that came with the power unit and liberally fill both slots with a heavy, axle-type, grease.4. Insert the coupling into the power unit adapter so the pump shaft tang engages the female slot fully.5. Position the 56C adapter plate on the 550 Series Power Unit adapter so the four through holes align with the four through holes in the power unit adapter.6. Turn the motor shaft so the tang on the shaft adapter will align with the up-facing coupling slot, then carefully lower the electric motor vertically onto the power unit/56C adapter plate so the four studs pass through the four through holes. If the motor face, the 56C adapter plate and the 550 Series Power Unit adapter are not tight together, reposition the motor shaft until it aligns with, and mounts into, the coupling slot.

7. Turn the four nuts onto the four studs until all are finger tight, then torque the four nuts to 20 +/- .5 Nm (180 +/- 5 in-lbs).Installation is now complete. Follow the start up instructions on page 10.
