2 fault groups can be selected. If any of the faults in a fault
group occurs, a fault signal is given.
Fault group consists of:
• Phase loss fault
• Fieldbus fault
• Frequency fault
• Heat sink over-temperature fault
• By-pass doesn't open fault
• Connection fault
• Non conducting thyristor fault
• Line side fault
• Kick-current fault
• Internal fault
• Fault Line/Delta
Shunt fault group consists of:
• Thyristor short circuit fault
• By-pass doesn't open fault
The shunt fault signal can be used to trip an upstream
breaker in case the softstarter is not able to stop the motor.
