18. Troubleshooting chart

Fault Probable cause
Short-circuit - Motor or cable short-circuit
- Wrong power supply connection
- Wrong connection of the cable shield
Frequency - Ambient temperature too high
converter - One or more frequency converter fans
overheating faulty
Low supply voltage - Supply voltage lower than 330V
High supply voltage - Supply voltage higher than 520V
Overcurrent - Step up/down ramp too high
- Improper connection of the motor
- Wrong motor settings
Electronic card Electronic card overheating
overheating
Dry-run The pump is running with no water
1) For electrical reparation, disconnect the supply voltage from the frequency converter. Refer to the safety
regulation described in section 4.
