Characteristics of the unit


BeWa OFX 3796731 en-us 2014-03-31.doc 2014-03-31

Characteristics of the unit

The filtration unit OFX serves as a portable service unit for filling and draining hydraulic systems. Due to the maximum permitted operating pressure of up to 45 bar, also supply circuits of hydrostatic transmission drives and work hydraulics in a closed circuit can be filled and vented.

The handy design and light weight make it ideal for service calls on mobile machines (e.g. construction, agricultural and forestry machinery, municipal vehicles).

Existing contamination and air pockets, for example after repairs, are specifically removed before commissioning in a very short time.

The filtration unit is suitable for:

Flushing and bleeding of hydraulic systems

Filtered oil change during maintenance

For filling preloaded hydraulic systems with filtrated, cleaned fluid.

For filling hydrostatic drives after service or repairs.

NOTICE

Danger of tipping over / danger of slipping due to vibrations

The unit will be damaged

► Prior to operation, place the unit on a stable, horizontal surface.

Prepare the unit for operation by following the following steps:

1. Check the connector cable for damage. If the connector cable is damaged, replace it immediately.

2. Check the suction and pressure hose for damage. Replace damaged hoses immediately.

3. Clean the suction strainer. See page 39 for details.

4. Prior to each use, match the oil type in the unit to the oil type to be pumped. If you are unsure which type of oil is in the unit or you would like to use a different type of oil than was previously pumped, completely drain the pump and replace the filter element.

Different types of oil blend together. Oil properties can change.

5. The unit is ready for the next steps on the following pages.



BeWa OFX 3796731 en-us 2014-03-31.doc 2014-03-31

Electrical connection

Hanging the suction hose

NOTICE

Danger due to severe contamination in the fluid / on the bottom of the tank.


► Never prime without a built-in suction screen.

► Do not prime directly at the bottom of the tank.

► Do not prime in the sump.

The greatest contamination is found on the bottom of the tank. All impurities and other particles are deposited on the bottom of the tank.

Put the suction hose with lance, without tension and or twist, into the appropriate tank. Secure the suction hose so that it cannot fall out our float.

Connecting pressure hose to high-pressure port

Connect the pressure hose (4.1) to the hydraulic system to be filled.

Connecting pressure hose to depressurized tank

Put the pressure hose (4.1), without tension or twist, into the appropriate depressurized tank. Secure the suction hose so that it cannot fall out our float.

Prevent aeration of the medium by fully immersing the lance in the medium.

Make sure that the lance is always below the oil level in operation.

Danger due to missing suction strainer / operation without a suction strainer


► Never operate the unit without a suction screen.

► Check / clean the suction strainer regularly.

To protect the pump from coarse contaminant particles there is a suction strainer in the suction port. Clean the suction strainer regularly.

Suction strainer cleaning interval

The suction screen (2.42) has a much larger absorption capacity at a mesh width of 300 µm.

Change interval Suction strainer

- every 250 hours*

- at least monthly*

- at every filter change*

300 µm

*) For heavily contaminated fluid, the maintenance intervals shorten.

To replace the suction strainer, proceed as follows:

1. Switch the filtration unit off.


3. Turn the hose coupling (3.1) counterclockwise by ~ 90° and remove it.

4. Drain the fluid in the suction hose back into the tank

5. Remove the suction hose from the tank and wipe off any fluid remaining on the suction hose and lance using a cloth.

6. The suction screen (2.42) is now visible and can be accessed via the hose coupling (2.41).

7. Remove the suction screen (2.42) from the hose coupling (2.41).

8. To clean the suction screen (2.42), wash it out and then dry it using compressed air.

6. Insert the new or cleaned suction strainer (2.42) into the hose coupling (2.41).

9. Attach the hose coupling (3.1) to the counterpart on the unit (2.41) and turn the hose coupling (3.1) in a clockwise direction by ~ 90 °.

10. Tighten the collet (3.2) on the hose coupling (3.1) by turning it clockwise.

If the collet is not tightened or not sufficiently, the pump will take in air via the hose coupling.

11. Start up the unit.

12. Check the unit for leaks while in operation.

13. Checking / replacing the suction screen is complete.

Errors and troubleshooting


BeWa OFX 3796731 en-us 2014-03-31.doc 2014-03-31


Error Cause(s) Remedy

The is no power at the electric motor.

The power outlet used is free of voltage.

The mains connector is not plugged in. Plug in the power plug.

Inspect the unit supply line for damage. If the unit supply line is defective, replace it immediately.

The mains voltage or frequency do not correspond to the specifications on the unit.

Use a unit that is suitable for the mains voltage.

The unit is switched off at the operating switch.

Turn the unit on at the operating switch.

Electric motor / pump is not running

The thermal overload protection was triggered.

Reset the thermal overload protection. For details refer to page 44 in Section "Resetting overload protection".

The hose coupling is leaking

Retighten the screw connection on the hose coupling.

The suction strainer is clogged

Check or clean the suction strainer.

The suction hose is kinked or faulty or a shut-off device is closed

Check the suction hose for flow. Replace it if necessary.

There is air in the suction line and the pump

Fill the pump via the suction hose / hose coupling.

No oil flow

The viscosity of the fluid is too high

Check the viscosity of the medium.

Heat the medium to reach the permissible viscosity.



BeWa OFX 3796731 en-us 2014-03-31.doc 2014-03-31

Error Cause(s) Remedy

There is no voltage supply to the electric motor.

Check the supply line to the filtration unit. Replace it if necessary.

The electric motor / pump is defective

Contact HYDAC.

The transport seals have not been removed.

Remove the transport seals.

Transport seals are the yellow plastic plugs.

The fluid is heavily contaminated.

The contamination retention capacity of the filter element has been reached.

Replace the filter element. The filter is clogged

(Clogging indicator appears)

The viscosity of the fluid is too high.

Check the viscosity of the medium.

Heat the medium to reach the permissible viscosity.

Wrong, missing, or defective sealing ring.

Check the sealing ring on the filter element. Replace it if necessary.

Leakage on the unit / filter housing

The filter element is insufficiently tightened.

Tighten the filter housing somewhat by hand.



BeWa OFX 3796731 en-us 2014-03-31.doc 2014-03-31

Resetting overload protection

The unit has a thermal overload protection (6.90) to protect the electric motor.

If the thermal overload protection has been triggered, the electric motor no longer runs. Reset the thermal overload protection by pressing the switch.

If the overload protection is triggered again, check the viscosity of the fluid and the suction and pressure hose for flow rate.

If all conditions are within the permitted range, the cause may be a technical flaw in the electric motor or pump. Contact HYDAC Customer Service.
