CONTROLS AND INDICATORS
On/Alarm Silence/Manual Battery Test Button
This button controls output power to connected load(s) and has three functions:
On, Alarm Silence, and Manual Battery Test. Pressing this button will start up
the UPS in order to provide conditioned and protected power into the utility
socket.
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.
To initiate a manual battery test, press this button for at least one half second
while operating from utility power and no alarm conditions are present.
If the bottom two LEDs 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 retested and the bottom two LEDs still do not illuminate,
contact your dealer or Liebert Technical Support (LTS) for a battery replacement
kit.
Off/Bypass Button
This button controls output power to connected load(s) and has dual functions:
Off and Bypass.
CAUTION:
Pressing this button once 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 sockets and connected loads. Perform all necessary
shutdown procedures on connected loads before pressing this button twice.
Load/Battery Level Indicators (4 Green, 1 Amber)
The Load/Battery Level indicators have dual functions. During normal mode
operation LED indicators display the approximate electrical load placed upon the
UPS; and during battery mode operation LED indicators display approximate
battery capacity. Refer to the Typical Battery Discharge Curves to determine the
approximate amount of back up time with respect to your connected load
percentage.
The UPStation GXT™ is equipped with automatic and remote battery test
features. The automatic test occurs every 14 days if utility 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.
Fault Indicator (Red)
The Fault indicator is illuminated if the UPS has detected a problem. Also, one or
more of the load/battery level indicators may be illuminated (refer to
Troubleshooting Guide).
Bypass Indicator (Amber)
The Bypass indicator is illuminated when the UPS is operating from bypass
power. An alarm will sound indicating the UPS detected a problem, or the
manual bypass function has been activated.
