LCD Status Screen
The LCD Status Screen indicates a variety of UPS
operational conditions. All descriptions apply when the
UPS is plugged into an AC outlet and turned on.
Note: The LCD will illuminate for 1 second when the
UPS is plugged in, before it is turned on. The LCD
Status Screen can be rotated for easy viewing, regard-
less of whether the UPS is in a horizontal or vertical
position. To rotate the LCD Status Screen: insert a small
tool in the slots on the sides of the screen to pop it out
of the UPS housing; rotate the screen, and snap it back
into the UPS housing.
3a) “Input Voltage” Meter: This meter measures,
in real time, the AC voltage that the UPS system is
receiving from the utility wall outlet. Although the
Meter may occasionally display input voltages which
stray outside the range of standard computer tolerance
(due to poor quality utility service), rest assured that the UPS is designed (through the use of automat-
ic voltage regulation) to continuously supply connected equipment with stable, computer-grade output
voltage. In the event of a blackout (power loss), severe brownout (low power) or overvoltage (high
power), the UPS will rely on its internal battery to supply computer-grade output voltage.
3b) “BATTERY CAPACITY” Meter: This meter displays the approximate charge level (in 20%
increments) of the UPS's internal battery. During a blackout or severe brownout, the UPS will switch
to battery power, the “ON BAT” icon will be illuminated and the charge level will deplete.
3c) “AVR” (Automatic Voltage Regulation) Icon: This icon will illuminate whenever your UPS is
automatically correcting AC line voltage without depleting battery power. This is a normal, automatic
operation of your UPS, and no action is required on your part.
3d) “REPLACE” (Battery Recharge/Replace) Icon: This icon will illuminate and an alarm will
sound after a self-test to indicate the UPS battery needs to be recharged or replaced. Allow the UPS to
recharge continuously for 24 hours, and repeat the self-test. If the icon continues to illuminate, contact
Tripp Lite for service. Battery replacement should only be performed by qualified service personnel.
3e) “ON BAT” (On Battery) Icon: During a severe brownout or blackout, this icon illuminates and
an alarm sounds (4 short beeps followed by a pause) to indicate the UPS is operating from its internal
batteries. Monitor the “Battery Capacity” Meter to determine the approximate battery charge level
available to support equipment. During a prolonged brownout or blackout, the alarm will sound
continuously (and the “BATTERY CAPACITY” Meter will show one 20% capacity segment shaded)
to indicate the UPS's batteries are nearly out of power; you should save files and shut down your equip-
ment immediately.
3f) “FAULT” Icon: This icon will illuminate and an alarm will sound after a self-test to indicate the
battery-supported outlets are overloaded. To clear the overload, unplug some of your equipment from
the battery-supported outlets and run the self-test until the icon is no longer illuminated and the alarm
is no longer sounding.
CAUTION! Any overload that is not corrected by the user immediately following a self-test may
cause the UPS to shut down and cease supplying output power in the event of a blackout or
brownout.
