Avoiding injuries and damages:
– Malfunctions may only be repaired by sufficiently qualified and authorised persons.
– Secure devicece against unintentional start-up. I.e.switch main switch off and secure with lock.
– Secure range of action of moving components.
– Safety instructions --> Chapter 2.
malfunction Possible causes:
No power supply
Fuse melted
Interruption in the control cable
The motor does not run
The brake does not vent
The switching unit in the control switch is defective
Start up or operating capacitor defective (220 V)
The overload protection (as of 1000 daN rope tensile
force) is released (with overload)
The motor runs - the load is
not hoisted
The overload protection (as of 1000 daN rope tensile
force) is released (with load ≤ nominal load)
Coil or capacitor defective (220 V)
The motor hums and has a
The rotor drags
high power consumption
The brake does not vent
Winding damage Overload (mechanical or electrical)
Worn or oiled brake pad
The motor does not brake
Excessive air gap
or the castor is excessive
Circuit fault after electrical circuit modification
Defective brake coil
Defective rectifier
The brake does not vent
Exceedance of the permissible air gap due to worn
brake pad
Voltage drop in the supply line > 10 %
Motor or line short circuit
The fuses blow or the motor
Short circuit to frame or winch short circuit in the motor Repair motor
protection is released
(consider item 8.9)
Incorrect motor circuitry
Incorrect fuse type
Our service department will be glad to help you, if you have any questions (Chapter 1.3).
