Problem

Possible cause

Actions

Control unit does not work.

A buzzer sounds.



Runways misaligned. Misa-

lignment protection activated.

Lower the lift or rolling jack,



Chapter 6. Authorized lowering.

The main lift does not react
when being lowered.

Only rolling jack can be lowered.

A buzzer sounds



Cable too slack or damaged.

Slack cable switch activated.

Tighten and adjust cable
(



Chapter 11.11 und 13.4),

Change if necessary.

Lower lift completely (



chap-

ter 6).

Carry out function test.

Lift does not work.

A buzzer sounds



Fuses damaged.



Thermal protection discon-

nected.



Transformer damaged.

Depending on cause:

●

Reset or replace fuses.

●

Connect thermal protection.

●

Replace transformer.

The motor is not running.



Incorrect supply voltage to the

motor.



Wiring loose.



Faulty motor.



Faulty limit switch.

Depending on cause:

●

Supply the correct voltage to

the motor.

●

Check all wiring connections

and repair or insulate if neces-
sary.

●

Test function of the Up switch.

Replace if necessary.

●

Check function of overhead

limit switch. Replace if necessary.

●

Change hydraulic power unit for

motor.

Up button does not work.



Suction pipe disconnected

from pump.

Depending on cause:

●

Clean or replace lowering

valve.

●

Tighten fittings on suction pipe.

●

Replace suction pipe.

Runways do not lift with a load.
Runways rise however without a
load.



Depending on cause:

●

Supply the correct voltage to

the motor.

●

Clean the lowering valve.

●

Adjust release valve.
