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 147. 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.
