LED (Light Emitting Diode) Functions

The following list describes the conditions necessary for each LED lamp to be "on."

This green LED lamp is "on" when the UPS is operating normally within specifications. If there is no power failure and the input voltage is in an under-voltage condition, the AC IN lamp will be "off." If there is no power failure and the input voltage is in an over-voltage condition, the AC IN lamp will flicker on and off rapidly (0.4 sec "on" and 0.4 sec "off").

This green LED lamp is "on" when the UPS inverter is operating.

This green LED lamp is "on" when the UPS is in the static Bypass Mode.

This green LED lamp is "on" when the UPS is in the Battery-Discharge Mode. If the battery is low during a battery discharge, the BATT lamp will flicker on and off slowly (1.2 sec "on" and

1.2sec "off"). The BATT lamp will go "off" if the battery voltage reaches the shutdown level during the Battery-Discharge Mode.

FAULT

RED

This red LED lamp is "on" when the UPS is in a fault condition.

5.14.1LED (Light Emitting Diode) System Status

The following chart shows the UPS system status that can be determined by decoding the "on" and "off" condition of the LED lamps. It should be used in conjunction with the LCD display and the audible alarms for total system monitoring.
