LED and ALARM FUNCTIONS
WEAK / BAD / DISCONNECTED BATTERY
The UPS automatically tests the battery’s condition. If the battery is weak, bad
or disconnected, the Warning/Fault LED will turn on and the alarm will sound
three beeps every five minutes until the battery is either reconnected, re-
placed or passes a self-test. The audible alarm cannot be silenced during the
Weak/Bad/Disconnected Battery alarm. It is recommended that the UPS be
allowed to charge overnight before performing a battery test to confirm a
Weak/Bad Battery condition.
OVERLOAD
When the amount of load attached to the UPS exceeds its power rating, the
Warning/Fault LED will turn on and the alarm will sound one beep every half a
second (AC and Battery modes). This alarm will remain on until the excess
load is removed or the UPS’s self protection circuit shuts the UPS down. If the
UPS has shutdown, remove part of the load and then press the On/Off button
to turn the UPS on. The audible alarm cannot be silenced during the Overload
alarm.
ALARMS
BATTERY MODE
When the UPS is operating in the Battery mode, the AC normal LED will turn
off, the On-Battery LED will turn on and the alarm will sound one beep every
five seconds. Once the UPS returns to the normal AC mode, the alarm will
stop, the On-Battery LED will turn off and the AC normal LED will turn on.
LOW BATTERY WARNING
When the batteries reach the predetermined level, the Warning/Fault LED will
turn on and the alarm will sound two beeps every five seconds. The audible
alarm cannot be silenced during the LBW alarm. This information is to inform
the user that there is approximately two minutes of runtime remaining before
the UPS shuts down. This condition will continue until either AC returns or the
UPS’s self protection circuit shuts the UPS down to protect the battery from
over discharging.
UPS FAULT
When the UPS detects an internal fault, the Warning/Fault LED will turn on
and the alarm will sound continuously and the output will be turned off. The
audible alarm cannot be silenced during the Fault alarm.The fault condition, in
some instances, may be cleared by turning the UPS off and then back on
again. If the fault condition does not clear the UPS must be sent in for service.
See the Troubleshooting section.
TURNING THE UPS ON / OFF
To turn the UPS on: press and hold the On/Off button until the alarm sounds
one beep and then release. Then in aproximately twenty seconds the UPS will
perform a five second self-test. Once the UPS has passed its self-test the
UPS will be ready for normal operation. To turn the UPS off: press and hold
the On/Off button until the alarm sounds one beep and then release. The UPS
will continue to charge the batteries whenever it is plugged into a wall outlet
and there is an acceptable AC voltage present (95 - 140VAC).
ALARM SILENCER BUTTON
When the unit is operating in Battery mode, pressing the Alarm Silencer But-
ton will silence the audible alarm. Once the UPS reaches the LBW (Low
Battery Warning) threshold the alarm will start beeping. The alarm cannot be
silenced during the LBW alarm or any fault condition. Once the UPS trans-
fers to the AC mode the alarm will be reset to default.
