Alarms
ON-BATTERY
When the UPS is operating on the batteries, the On-Line LED will blink and the
audible alarm will sound every 10 seconds. The alarm will stop once the UPS
returns to On-Line operation.
UPS FAULT
When the UPS detects a hardware fault, the Fault LED will illuminate and the
UPS will emit a sustained tone. The fault condition can be reset by turning the
UPS OFF and then ON.
OVERLOAD
When the amount of load attached to the UPS exceeds its power rating, the
Overload LED will illuminate and the UPS will emit a sustained tone. This alarm
will remain on until the excess load is removed or the UPS self-protection circuit
shuts the UPS down.
REPLACE BATTERY
The UPS automatically tests the battery condition and will illuminate the
Weak/Bad Battery LED and emit a short beep. This tone will be repeated every
hour until the battery passes a self-test. It is recommended that the UPS be
allowed to charge overnight before performing a battery test to confirm a
Weak/Bad Battery condition.
LOW-BATTERY WARNING
The UPS will emit two consecutive beeps every five seconds when the battery
reserve runs low. This continues until AC returns or the UPS shuts down from
battery exhaustion.
