Acknowledging faults or alarms in alarm/fault log
When the alarm/fault log has more than 256 unacknowledged faults or alarms, the display
shows the message "Fault/Alarm log" "overflow".
The cause may be an alarm or several that have not been manually reset to "acknowledge"
the alarm.
An alarm sets and resets itself with no external intervention. However, to acknowledge an
alarm, you must manually reset the alarm using the fault reset button or remote fault reset.
