Minor Faults and Alarms
When a minor fault or alarm occurs, the ALM LED flashes and the text display shows an alarm code. A fault has occurred
if the text remains lit and does not flash.
Refer to Alarm Detection on page 241
. An overvoltage situation, for example,
can trigger both faults and minor faults. It is therefore important to note whether the LEDs remain lit or if the LEDs flash.
