■ Minor Faults and Alarms
Table 6.11 give an overview of possible alarm codes. As conditions such as overvoltage can trip both a fault and alarm, it
is important to distinguish between faults and alarms in order to find the right corrective action.
If an alarm is detected, the ALM LED will blink and the alarm code display flashes. The majority of alarms will trigger a
digital output programmed for alarm output (H2-
fault has been detected (not an alarm). Information on fault codes can be found in
