Possible Problem(s) Possible Solution(s)
MAJ Battery on
Discharge
Norm
green
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.

Rect)

• Rectifier output has dropped
below 18V (36V), rectifier has
shut down 30 .
• Excessive ambient temperature,
rectifier has shut down.
• A rectifier or rectifier fan has
failed.
• A rectifier high voltage shut
down 30 .
1. Verify that there is no obstruction of the airflow path and fans
are turning.
2. Reset the rectifier by removing the rectifier, waiting
approximately 30 seconds, and replacing the rectifier.
3. If problem persists, replace the rectifier.
4. If problem still persists, call your local field representative.
30 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.
