5
Input thyristor failure
Failure of input thyristor
6
Battery discharge thyristor
failure
Failure of battery discharge thyristor
7
Battery charge thyristor failure
Failure of battery charge thyristor
8
Fan fault
At least one of the cooling fans fails. Rectifier and
inverter and charger shut down.
9
DC Bus over-voltage
Rectifier, inverter and battery converter are shutdown due
to high DC bus voltage.
10
DC Bus under-voltage
Rectifier, inverter and battery converter are shutdown
due to low DC bus voltage.
11
DC bus unbalance
If the difference between positive DC bus and negative
DC bus exceeds 30V, this warning shall occur.
12
Soft start fault
Rectifier could not be started due to low DC bus voltage
