Overload
Lifting blocked
 Put down the overload and reduce the load
 Correct the cut-off threshold (during commissioning,
with test load)
Overheating 1 or
thermistor error
Lifting and
lowering
blocked
 Let the motor cool down the error state is
acknowledged automatically
 Check the wiring of the thermistor
 Check the thermistor resistance with the motor cold:
– If the measured resistance is 150...750, the
thermistor input is defective and the device must
be replaced.
– If the resistance is greater or smaller, the ther-
mistor is defective and the motor must be re-
placed.
Offset correction error
Lifting blocked
 Existing device: check the load sensor  see above
 New device: carry out offset calibration
 If the error occurs in testing bay mode, then check
the load sensor wiring
Lifting and lowering
actuated at the same
time
Lifting and
lowering
blocked
 Error in the wiring.
 Check the control cables to the terminals 3, 4 and 5
at the SLE
Internal error
Lifting and
lowering
blocked
 Check the voltage at terminal 6
 Restart the device
 If the error occurs again after a restart, the device
must be replaced
No power supply
