3. Operation
“LOAD” LED:
This green LED will illuminate when the UPS system
is receiving AC power. It also indicates that the % level LEDs (25%,
50%, 75%, 100%) are displaying the UPS load level.
“BATT” LED:
This green LED will illuminate when the UPS system
is operating from battery power. It indicates that the % level LEDs
(25%, 50%, 75%, 100%) are displaying the battery charge level.
(The “ON BATT” LED will also be illuminated.)
% Level LEDs:
These dual-function LEDs will indicate the % level
for either the load level (if the “LOAD” LED is lit) or the battery
charge level (if the “BATT” LED is lit).
“OVERLOAD” LED:
This red LED will illuminate continuously to
indicate that the UPS system’s capacity has been exceeded. The
UPS alarm will beep continuously. Immediately unplug some
equipment until the LED and alarm go off. If the overload is not
corrected immediately, the UPS system will go from on-line to
bypass mode.
“BATT LOW” LED:
This yellow LED will illuminate when the UPS
system’s battery charge level is low. The UPS alarm will beep until
the batteries are either depleted or adequately recharged.
“ON BATT” LED:
This green LED will illuminate continuously to
indicate that AC line voltage is absent (or out of range) and the
UPS system is providing equipment with battery-derived AC power.
The UPS system will also beep every two seconds (unless silenced
by the “ON/TEST” button) and the % level LEDs (25%, 50%, 75%,
100%) will display the battery charge level.
“REPLACE BATT” LED:
This red LED will illuminate continuously
and the UPS alarm will beep every two seconds if the UPS system
fails the automatic self-test. Allow the UPS system to charge for at
least 12 hours and perform a self-test as described in
Section
3.1: Front Panel Switches
. If the condition persists, contact
Tripp Lite.
