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 238. 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.
