In case of disturbance or defect, secure the lift against authorized person. Phone your
service partner.
6.2 Driving onto an obstacle
If the platform or the lifting carriage is lowering on an obstacle, the motor from this side will be
locked. The lift switched off if the lifting carriage are not more in the regulation range
(approx. 50 mm).
An additional protection is the temperature control system in the motor. It interrupt the
electrical circuit when it is overloaded. You can not work with the lift. Cool down
approx. 5 – 10 min. dependently on the outside temperature.
After the locking of the motor, examine the V-belt, if necessary exchange it. Call your service-
partner.
6.3 Function of safety device
The lift is equipped with a safety switching, which controls the wear of the main nut.
If the lifting nut is broken, a safety nut which is conducted loose in the spindle, carries
the load. After a break of the nut, the lift can only once being lowered in the lowest
position. If the lift has reached the lowest position it is not possible to raise the lift again.
The lifting carriage of the broken side gets mechanically locked. During the lifting the
other side is driving out of the regulation range and switched off the lift. You can not
work with the lift anymore. Call the service-partner.
If the safety device is active, Shut down the lift and phone your the service partner!
Switch off the main switch at all repairs and disturbances!
The electrical system may only be opened by trained persons!
6.4 Manually equalisation of the carriage
The lift is equipped with a position measuring system which guarantee the
synchronisation of the lift. The electrical control recognises if one lifting carriage is
approx. 20 mm earlier at the definite height. The electrical control stopped the motor of
this carriage until both carriage have the same height again. After it both motors are
working together again.
If the carriages of the lift are driving out of the regulation range/switching off window
of approx. 5 0mm), the electrical control recognises this and
switched off the lift.
To reach the normal function of the lift you must equal manually the carriages. Remove
the cover of the V-Belt pulley at the top of the lift. Equal the lift: turn the nuts until the
carriages have the same height.
• Carry out the equalisation with the lift only without load.
• Open the electrical box.
• See the DIP-switches on the controller (Pos.2).
