defective limit switch has been repaired or replaced, run 2-3 lifting cycles
without load.
Drive-on protection (antilock system)
If when lowering the lift any item, e.g. a tool car, should have been left under
the lift, the automatic drive-on protection or antilock system actuates. The
system automatically switches off the lift and does only permit to move the
unit upward. It is thus simulated that the carriages have reached the lower
limit of travel. After the item under the lift has been removed, the lift can be
further operated. If the emergency switch should actuate proceed as
described above (‘Failure of the
lower limit switch’).
Short circuit protection
The short circuit protection works automatically. It must be checked whether
the ratings of the safety plug correspond to the ratings given in the circuit
diagram. Overload protection is granted by the built-in thermal protector. If
an overload should occur the thermal protector interrupts the operation. No
actions by the operator are required. Please verify that the value is actually
set to the required 7.0 A. To verify the protection against accidental contact,
the correct connection of the earth leads should be checked.
Failure of the control cable
In case of a defect or even tear of the cable of the control cable switch
system an emergency switch-off will always occur. After an emergency switch-
off, the lifted load is manually lowered and removed from the lift as described
above (‘Failure of the chain’) after the unit power supply has been
disconnected. The torn cable is replaced by a new one and inserted
according to Fig. 6. The lift is put into operation as described in section 4.0.
Pay attention to the correct adjustment of the switch system!
ATTENTION!
A torn control cable must neither be repaired nor completed and reassembled!
This is strictly forbidden! Always use a new control cable! Measures to be taken in
case of an accidental defect: the unit must be shut down anytime an unusual
event occurs during operation. The correction of failures should be left to an
expert or authorised service personnel. The operation of the lift is forbidden unless
the failure has been corrected! The lift must be disconnected from its power
supply and protected from unauthorised return to service.
Safety directions
The lifting unit must only be operated with its protection covers and safety
devices properly installed. If the lift should be exposed to the danger of a
potential unauthorised use the selector switch must be secured in position ‘0’
using a padlock.
