Fault Cause
Fault Blocked rotor
Contact/winding Faulty winding
Supply side voltage too low/
Under/overvoltage
high
Excessive module tem-
Inside of module too hot
perature
Short circuit Motor current too high
The hydraulic system of
Turbine operation pumps is fed but the pump
does not have mains voltage
Dry running Air in pump
The motor turns with difficulty.
Pump operation not in accord-
ance with specifications (e.g.
Overload
high module temperature).
The speed is lower than in
normal operation.
Cure
Activate manual restart or
contact Customer Service
Check the mains voltage
and conditions of use.
Request Customer Service
Check the mains voltage,
the water flow/pressure as
well as the environmental
conditions
