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
Note: An overvoltage situation can trigger both faults and minor faults, therefore it is
important to note whether the LEDs remain lit or if the LEDs flash.
The following table illustrates LED operator after minor faults or errors.
