ALARMS
Alarms indicate faults, power outages, and UPS battery operation. The tone pattern varies
according to the alarm:
On-Battery / Utility Failure Alarm - one beep every 4 seconds (greater than 2 minutes
battery time remaining). Silence this alarm by depressing the ”Alarm Reset” switch for a
half-second. After silencing it, the low battery alarm still sounds at the appropriate time.
Low Battery Alarm - 4 beeps per second (less than 2 minutes battery time remaining).
Silence this alarm by depressing the ”Alarm Reset” switch for a half- second.
UPS Shutdown - A long continuous tone occurs for a few seconds after the UPS is off.
Then the controls and display shut off.
High Temperature Alarm - This alarm, along with a flashing FAULT indicator, indicates
excessive internal UPS temperature. This alarm is two long beeps per second. Though
the UPS continues to support its critical load, correct the condition immediately. Poor
ventilation, prolonged overloads, or high-temperature environments may cause
overheating. Immediately save work in process and correct the problem.
TROUBLESHOOTING
If the UPS shuts down due to a fault condition, the ”FAULT” indicator lights. The ”FAULT”
indicator also lights if the UPS exhausts its battery or receives a shut- down command via
its communication interface port.
In addition to the ”FAULT” light, one of several different LED segments in the ”LOAD” or
”CAPACITY” bar indicators light briefly also. These LED segments will indicate the name
of the fault condition and the reason for the
shutdown.
A. Over-temperature condition.
B. Output overload condition.
C. Internal fault.
D. UPS output is short-circuited.
E. Internal fault.
F. UPS shutdown due to battery exhaustion.
G. UPS shutdown on command from
communication interface port.
If only the Fault LED lights, it indicates the UPS is in Bypass mode.
Refer to the Troubleshooting Guide on the next page to determine what to do if your UPS
shuts down and indicates one of the shutdown codes.
