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 140. 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.
