WEAK/BAD BATTERY
The UPS automatically tests the battery’s condition. If the battery is weak, bad
or disconnected, the Battery Capacity Bar Graph will flash 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 confirm 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 perfom 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 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 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 and the Battery Bar Graph will display the remaining
battery capacity. 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, "FAL" will be displayed on the LCD
screen, the alarm will sound continuously and the output will be turned off. The
fault condition, in some instances, may be reset by turning the UPS off and
then on. If the fault condition does not clear the UPS must be sent in for
service.

SELF-TEST
The self-test feature is useful to verify the correct operation of the UPS and the
condition of the batteries. The length of the test that is automatically performed
every two weeks is longer than the start-up or user invoked test. This every two
week test will run for approximately fifteen-seconds to measure the battery’s
capability to support the output load. The start-up and user invoked test will run
for approximately ten-seconds. If the UPS fails one of these tests, one of the
icons or the information displayed on the LCD will remain illuminated indicating
the type of problem. NOTE: The UPS will automatically perform a self-test on
start-up and every two weeks.
SCROLL BUTTON
Press the Scroll Button to scroll through the UPS parameters. The UPS pa-
rameters are displayed on the LCD screen.
LCD SCREEN
The LCD provides the user with a variety of useful information. The LCD has a
real-time meter to display, in numeric fashion, the following data:
Input Voltage and Frequency
Output Voltage and Frequency
Connected Load Capacity
Battery Capacity
Estimated runtime in the AC and DC mode
The LCD will include dedicated icons for the following information:
AC Normal
On Battery
AVR Mode (Boost and Buck) – The AC Normal icon will flash
Overload
Weak/Bad Battery (Battery Capacity Bar Graph will flash)
Site Wiring Fault (S.L.F. will be displayed)
UPS Fault (FAL will be displayed)
The LCD does have a backlight that will turn on when the UPS is turned on.
After approximately 20-seconds the backlight will turn off to conserve energy.
When an event (alarm) occurs, such as going to the battery mode, the back-
light will turn on for approximately 20-seconds to alert the user that an event
has occurred and then the backlight will turn off. While the Scroll button is in
use the backlight will remain on. Approximately 20-seconds after the Scroll
button has stopped being used the backlight will turn off to conserve energy.
BATTERY OVER CHARGE PROTECTION
If the charger is providing too much voltage to the battery the UPS will turn off
the charger to protect the battery. When the charger voltage exceeds 14.52V/
battery the charger will turn off. The alarm will sound three beeps every five
seconds and the Battery Capacity Bar Graph will flash. In some instances, the
charger may be reset by turning the UPS off and then on. When the charger
voltage exceeds 15.0V/battery the charger will turn off. The alarm will sound
three beeps every five seconds and the Battery Capacity Bar Graph will flash.
The UPS will automatically transfer to the battery mode and operate until the
UPS shuts down due to battery exhaustion. The UPS must be sent in for
service.
