WEAK/BAD BATTERY

The UPS automatically tests the battery’s condition.  If the battery is weak, bad
or disconnected, the  Weak/Bad Battery icon will illuminate and the Battery
Capacity Bar Graph will turn off and the alarm will sound three beeps every
five minutes until the battery is either reconnected or replaced.  This alarm will
be repeated until the batteries pass a self-test.  It is recommended that the
UPS be allowed to charge overnight before performing a battery test to con-
firm a Weak/Bad Battery condition.

OVERLOAD

When the amount of load attached to the UPS exceeds its power rating, the
Overload icon will illuminate and the alarm will sound continuously (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.

To clear the overload alarm when the UPS has shutdown requires that the UPS
perform a battery test.  First remove part of the load, then turn the UPS on, the
Overload icon and the alarm will be on.  Second either use the Test Button or
unplug the input power cord to perform the battery test.

ALARMS

ON BATTERY

When the UPS is operating on the batteries, the AC normal icon will extinguish,
the On-Battery icon will illuminate, the LCD will display the estimated runtime
remaining and the alarm will sound one beep every 10 seconds.  Once the
UPS returns to the normal AC mode, the alarm will stop, the On-Battery icon
will extinguish and the AC normal icon will illuminate.

LOW BATTERY WARNING

When the batteries reach the predetermined level, the alarm will sound two
beeps every five seconds, the Battery Bar Graph will display the remaining
battery capacity and the LCD will display error code E07.  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 Fault icon will illuminated and an
error code will be displayed on the LCD screen,  the alarm will sound continu-
ously and the output will be turned off.  The fault condition, in some instances,
may be cleared by turning the UPS off and then on.  If the fault condition does
not clear the UPS must be sent in for service.  See the Troubleshooting sec-
tion.
