Internal circuit fault
Resetting the converter initializes the cumulative value of the internal thermal relay.
The error message shows an operational error. The converter does not trip.
Warnings are messages given before faults occur. The converter does not trip.
Alarms warn the operator of failures with output signals. The converter does not trip.
When faults occur, the protective functions are activated to trip the converter and output the fault signals.
Assign the OH signal to one of Pr.3 to Pr.7 (Input terminal function selection) to enable the external thermal relay operation.
This protective function is not available in the initial status.
