Troubleshooting
In case of a fault, please proceed as follows:
Fault 1:
Electronics supply or motor too small (see technical data minimum motor
load). Send device to the producer to have it checked.
Fault 2:
Check the frequency of starts and the starting current and also observe
the max. ambient temperature. Give the device and/or the motor enough
time between starts to cool down. The heat dissipation can be improved
by forced cooling, e.g., by means of a fan mounted unterneath the device
or by using a motor with a separately driven fan.
Fault 3:
Defect in the internal control electronics. Send device to the producer to
have it checked.
Fault 4/5:
Mains supply is interrupted. Motor lead interrupted, power semiconductor(s)
defective, motor defective. Check motor and wiring. Send device to the
producer to have it inspected.
Fault 6/7:
Mains supply is interrupted. Power semiconductors do not trigger. Motor
rating is too small. Check as to whether the motor is suitable for the device
rating. Send device to the producer to have it checked.
Fault 8:
Mains or motor wiring is interrupted. Power semiconductor(s) defective.
Check wiring. Send device to producer to have it inspected
Motor load must always be connected as continuous operation of the
softstart with no load may cause overheating of the motor and softstart.
It is recommended that the softstart is protected by superfast semiconductor
fuses rated as per the current rating of the softstart or motor. However,
standard line and motor protection is acceptable, but for high starting
frequencies motor winding temperature monitoring is recommended.

Resetting of faults
The fault message can be reset by disconnecting and reconnecting the
supply voltage.
!
Warning:
At any rate, the cause of the fault has to be identified and remedied by
trained and qualified personnel. Only then must the device be put into
operation again.
Notes
!
Attention:
Please pay attention and consider for the operation of IE3 motors while
dimensioning of softstarters the resulting higher starting currents.
For the use of IE3 motors we highly recommend to dimension and design
the needed softstarters one size higher.
