DEFINITIONS FOR ILLUMINATED LCD INDICATORS
1. INPUT Voltage Meter: This meter measures
the AC voltage that the UPS system is re-
ceiving from the utility wall outlet. The UPS
is designed, through the use of automatic
voltage regulation, to continuously correct
output voltage to connected equipment
to a safe 110/120 voltage output range. In
the event of a complete power loss, severe
brownout, or over-voltage, the UPS relies
on its internal battery to supply consistent
110/120 output voltage. The INPUT voltage
meter can be used as a diagnostic tool to
identify poor-quality input power.
2. OUTPUT Voltage Meter: This meter mea-
sures, in real time, the AC voltage that the
UPS system is providing to the computer,
such as normal line mode, AVR mode, and
battery backup mode. (Note: The OUTPUT
voltage meter shows the status of the bat-
tery backup outlets.)
3. ESTIMATED Run Time: This displays the
run time estimate of the UPS with current
battery capacity and load.
4. NORMAL Icon: This icon appears when the
UPS is working under normal conditions.
5. BATTERY Icon: During a severe brown-
out or blackout, this icon appears and an
alarm sounds (two short beeps followed
by a pause) to indicate the UPS is oper-
ating from its internal batteries. During a
prolonged brownout or blackout, the alarm
will beep rapidly every 1/2 second (and
the BATT.CAPACITY meter shows one 20%
capacity segment shaded) to indicate the
UPS’s batteries are nearly out of power. You
should save files and turn o your equip-
ment immediately.
6. AVR (Automatic Voltage Regulation) Icon:
This icon appears whenever your UPS
is automatically correcting low AC line
voltage without using battery power. This is
a normal, automatic operation of your UPS,
and no action is required on your part.
7. SILENT MODE Icon: This icon appears
whenever the UPS is in silent mode. The
buzzer does not beep during silent mode
until the battery reaches low capacity.
8. OVER LOAD Icon: This icon appears and an
alarm sounds to indicate the battery-sup-
plied outlets are overloaded. To clear the
-continued
The LCD screen indicates a variety of UPS
operational conditions. All descriptions
apply when the UPS is plugged into an AC
outlet and turned on or when the UPS is
on battery.
