green
System voltage has fallen below the
battery on discharge threshold set
by the user.
1. Investigate other alarms that may be present such as rectifier
related problems.
2. If AC power is present but the system voltage remains low, call
your local field representative.

below 18V (36V), rectifier has
shut down
.
•
Excessive ambient temperature,
rectifier has shut down.
•
A rectifier or rectifier fan has
failed.
•
A rectifier high voltage shut
down
1. Verify that there is no obstruction of the airflow path and fans
are turning.
2. Reset the rectifier by removing the rectifier, waiting

When a rectifier or converter senses an over- or under-voltage condition it will shutdown, wait 4 seconds, and then attempt to restart. If the over- or under-voltage condition
remains it will cycle again. If the over- or under-voltage condition remains after 3 restart attempts the unit will lock out, and user intervention is required to restart.
