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.
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 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.
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 the ON 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 the ON 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 the ON 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 Technical Support 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 the OUTPUT OFF/BYPASS button once during normal
operation will cause the load to be transferred to BYPASS power if BYPASS
voltage is within +/- 17% of nominal. If the BYPASS voltage is outside this range,
transfer to BYPASS power will not be permitted to protect the connected load.
Pressing this button a second time within 4 seconds will result in loss of power to
the output and connected loads in all cases. Perform all necessary shutdown
procedures on connected loads before pressing this button.
