n 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 141 . 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.
