Liebert GXTTM User Manual page 7

The UPStation GXT is equipped with automatic and remote battery test features.
The automatic test occurs every 14 days if a manual battery test has not been
performed or if mains has not been interrupted (14 day timer resets if unit goes to
battery). Should the battery fail this test, the fault indicator along with the A and
C diagnostic LEDs will illuminate and an alarm will sound (refer to
Troubleshooting Guide). The remote test feature functions with either SiteNet® 2
or SiteNet® SNMP Manager software and can remotely initiate the battery test.
UPS ON/Alarm Silence/Manual Battery Test Button
This button controls output power to connected load(s) and has three functions:
UPS ON, Alarm Silence, and Manual Battery Test.
To start the UPS, while in the BYPASS mode, press this button until the
command is acknowledged by a beep from the audible alarm. This will provide
conditioned and protected power into the output terminal block.
To silence alarms, press this button for at least one half second while alarm
conditions are present. After the alarm is silenced, the UPStation GXT will
reactivate the alarm system to alert of additional problems.
NOTE: The low battery and BYPASS reminder alarms cannot be silenced.
BATTERY TESTING- To initiate a manual battery test, press this button for at
least one half second while operating in normal UPS mode power and no alarm
conditions are present. If the bottom two LED's do not illuminate during a Battery
Test, allow the UPS to recharge the batteries for 24 hours. After 24 hours, retest
the batteries. If the batteries have been re-tested and the bottom two LED's still
do not illuminate, contact your dealer or Global Services for a battery
replacement.
OUTPUT OFF/BYPASS Button
This button controls output power to connected load(s) and has dual functions:
OUTPUT OFF and Bypass.
CAUTION: Pressing this button once during normal operation will cause the load
to be transferred to BYPASS power. Pressing this button a second time within 4
seconds will result in loss of power to the output and connected loads. Perform
all necessary shutdown procedures on connected loads before pressing this
button twice.
