2.2 Proper use

• Thesetmustbeusedonat,stableanddryground,otherwisethesetmayfall.

• Do not park below the follower plate.

• Do not put your hands between the follower plate and the drum before and during the lowering or

raising of the plate.

• In the event of a hydraulic leak from FLUIDABIO, clean the area with clear water, having taken care to

isolate the system from the electrical and pneumatic connections.

• Beware of the risk of falling on the soiled or wet area.

• Before any operation on the system, disconnect the power supply, the compressed air and the

product delivery hoses.

• For any dismantling of the elements, use the appropriate lifting and handling means.

• Thepumpmustonlybeoperatedinaverticalposition(Seeoperatinginstructionpumptube)

• Only use the pump for suitable liquid.

• Avoid dry running.

- Make sure that the pump is only started with the liquid to be pumped and that it is not operated

without liquid.

• In the case of delivery of pump tubes without a motor, the addition to a pump unit must be carried

out in accordance with the provisions of the machinery directive 2006/42/EC.

If the product and supplied accessories are used for other purposes than the intended purpose, it is the

responsibilityoftheusertocheckthesuitabilityandadmissibility.Productusenotconrmedinwritingby

the manufacturer absolves the manufacturer of any liability. The manufacturer is not liable for consequences

andtear.Thesameappliesiffaultsarisefrominterventionorcongurationsonthepartoftheusernot

conrmedbythemanufacturer.

Prevention of obvious misapplications (examples)

• Respecttheoperatinglimitsofthepumpwithregardtotemperature,pressure,owrateandspeed.

• The power consumption of the pump increases with increasing viscosity of the pumped liquid.

Observe the permissible viscosity range to avoid overloading the pump, coupling and motor. Low

density and viscosity is allowed.

• Whenpumpingliquidscontainingsolids,observethelimitvaluesforsolidscontentandparticlesize.

• Do not use the pump tube to lift objects.

6. Starting up

Procedure for setting up the trolley with follower plate.

! DANGER

Incorrect connection of the plug could cause an electric

shock.

►Read the instructions for the plug carefully and keep it in a

safe place.

! WARNING

The unit may start uncontrolled when the power supply is

restored!

►Before connecting to the power source, check that all

switches are set to “OFF”.

►Connect the 400V 3~+N+PE plug to the mains socket A.

0697-051 - 06/2023

7. Extending the hydraulic system

! CAUTION

Risk of impact when lifting the plate.

► Make sure that there are no persons in the

vicinity of the moving parts.

Keep the push button "LIFT UP" ② pressed, until

the cylinder is completely extended.

Slight vibrations may occur during this process.

When the cylinder is in the extended position,

push the trolley under the pallet on which the

drum to be emptied is located.

Activate the brake on the two rear wheels B.

0697-051 - 06/2023

8. Lowering the follower plate onto

the uid

! WARNING

Other hazards may result from improper use

of the pump.

►Before starting operation, read the operating

instructions of the pump carefully.

When the trolley with follower plate is in the upper

position above the drum to be emptied, set the

switch "LOWER” ① for the hydraulic controls to

"ON".

The cylinder will then start lowering the follower

plate.

Make sure that the follower plate is centred on

the drum to be emptied and adjust it if necessary

during lowering.

Make sure that nothing can obstruct the lowering

ofthecylinder(drumcover,etc.).

Depending on the viscosity of the liquid, some

of the liquid may pass over the sealing lip of the

follower plate.

Do not reach with your hands between the

follower plate and the drum!

Pressing the black push button “STOP” ③ stops the

pump and the lowering of the follower plate.

To reactivate the pump, release the push button

and press the switch "PUMP ON/OFF" ④.

The pump must remain switched o until the

plate is lowered onto the uid level.

9. Emptying the drums

As soon as the follower plate is lowered on the

uidlevel:

Install the pressure hose using the appropriate

connections at the outlet of the pump.

(Seeoperatinginstructionsofthepump).

Set the switch "PUMP ON/OFF" ④ to the „ON“

position.

The transfer process is started, the follower

platelowerslinearlywiththeuidlevelinthe

container.

10. Finishing the emptying process

When the drum is empty, the limit switch stops

the pump B70 C.

Potentiometer „A“ D allows the detection

distance to be set for the pump to stop

automatically when the drum is empty. This must

be adjusted to the application depending on the

height of the pallets and containers.

Pressing the black push button “STOP” ③ stops

the pump and the lowering of the follower plate.

To avoid damage to the mechanical seal of the

pump, dry running must be excluded.

④

0697-051 - 06/2023

11. Raising the follower plate

Set the switch “LOWER” ① for the hydraulic

control to "OFF".

Open the ball valve for the compressed air supply

by opening the valve 1/4 turn. The incoming air

regulates the negative pressure that would occur

when the plate is extended E.

Press and hold the push button "LIFT UP" ②,

parallel to the incoming air, until the cylinder is

completely extended.

Close the compressed air ball valve as soon as the

plate is fully moved out of the drum.

Release the brakes on the two rear wheels and

pull the trolley away from the underside of the

pallet.

Then lower the cylinder again.

12. Disassembling the electric

motor

With the system switched o and the wheel

brakes tightened

Disconnect the compressed air hose, uncouple

the follower plate from the pump and the pump

tube from the motor G (see operating

instructionofthepump).

Open the cover of the frequency converter or the

terminal box and dismantle the cables, having

marked them beforehand.

Loosen and remove the 4 bolts with two 17mm

spanners and remove the motor I.

13. Venting the hydraulics

In the event of a jerky lowering of the cylinder,

the hydraulic system of the cylinder must be

vented.

Lift the cylinder halfway, open the plug (cap,

cover),pressthecoverwithasmallscrewdriverto

releasetheair.Assoonashydraulicoilows,stop

pressing and put the plug back on F.

0697-051 - 06/2023

14. Troubleshooting

Leakage of hydraulic oil

Check the hydraulic couplings for leaks

Replace them if they are defective.

Top up the oil level in the hydraulic unit tank if necessary.

Hydraulicoil(FLUIDABIO®-propyleneglycol+waterFDAapproved).

The hydraulic cylinder does not move upwards

Check the power supply

Check the hydraulic oil level in the tank of the hydraulic unit.

Check the hydraulic connections

Check that the switch “LOWER” for the hydraulic control ① is in the "OFF" position

The cylinder does not lift the follower plate into the drum

Check the power supply

Check the hydraulic oil level in the tank of the hydraulic unit.

Check the hydraulic connections

Check that the switch “LOWER” for the hydraulic control ① is in the "OFF" position

Check if there is compressed air at the pressure reducing valve.

Check if the compressed air ball valve is open

The cylinder does not move down

Check the power supply

Make sure that the stroke of the cylinder is not blocked

Make sure that the switch “LOWER” ① for the hydraulic control is switched on

Make sure that the hydraulic control valve is not closed

0697-051 - 06/2023

15. Recommendations

As a general rule, do not run the system without an operator nearby.

The operator must use the necessary protective equipment (e.g. face mask or goggles, apron and

gloves)whenhandlinghazardouschemicals.Thestatutoryorothersafetyandaccidentprevention

regulations must be observed.

Allworkonthehydraulicandelectricalcircuitsmayonlybecarriedoutbyauthorisedandqualied

personnel.

Use only original LUTZ parts for all repairs.

The system may only be moved in the retracted, lower position. Unless the system is above a container

andisinanycasexedinapalletwiththetwofootstabilisers.

Do not store anything under the follower plate.
