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:
Rectification
The motor does not run
No power supply
Check the power supply connection
Fuse melted
Replace the fuse
Interruption in the control cable
The brake does not vent
Refer to the "The brake does not vent" fault
The switching unit in the control switch is defective
Replace the switching unit
Start up or operating capacitor defective (220 V)
Replace the capacitor
The motor runs - the load is
not hoisted
The overload protection (as of 1000 daN rope tensile
force) is released (with overload)
Reduce the load to the nominal load
The overload protection (as of 1000 daN rope tensile
force) is released (with load ≤ nominal load)
Check the overload protection and readjust it if
required
The motor hums and has a
high power consumption
Coil or capacitor defective (220 V)
Repair motor
The rotor drags
The brake does not vent
Refer to the "The brake does not vent" fault
Winding damage
Overload (mechanical or electrical)
Repair motor
The motor does not brake
or the castor is excessive
Worn or oiled brake pad
Completely replace the pad support
Excessive air gap
Readjust the air gap
Circuit fault after electrical circuit modification
Check the brake's connection in accordance with the
circuit diagram
The brake does not vent
Defective brake coil
Replace the brake coil
Defective rectifier
Replace the rectifier
Exceedance of the permissible air gap due to worn
brake pad
Readjust the air gap, replace the pad support if
required
Voltage drop in the supply line > 10 %
Assure correct supply voltage
The fuses blow or the motor
protection is released
(consider item 8.9)
Motor or line short circuit
Eliminate the short circuit
Short circuit to frame or winch short circuit in the motor Repair motor
Incorrect motor circuitry
Correct the circuitry
Incorrect fuse type
Use appropriate fuse
