17 GTS Series Uninterruptible Power Manager
On/Off Button
The On/Off button is a dual function control:
• When the UPM is off and AC power is present to the UPM input,
pressing the On/Off button for more than 3 seconds will turn the
UPM on. If battery enable plug(s) are installed, pressing the
On/Off switch for 3 seconds or more will “cold-start” the UPM on its
internal battery.
• When the UPM is on, pressing the On/Off button for more than 3
seconds will turn off the UPM and output power.
Test/Silence Button
The Test/Silence button is a dual function control:
• Pressing the Test/Silence button when AC power is present and
the UPM is operating causes the UPM to enter a self test mode in
which it tests both battery and inverter for a few seconds before
returning to the AC supply. We recommend you close all open files
before initiating self-test.
• When AC power fails, the UPM warns you with an audible alarm.
The Test/Silence button is used to silence the alarm. When battery
power begins to run low, the audible alarm will automatically return
and beep at a faster rate.
Load Monitor
The Load Monitor is a 4-segment LED display that shows the current
load percentage. All the LED’s each indicate approximately 25% load.
Battery Charge Monitor
The Battery Charge Monitor is a 4-segment LED display that shows the
charge capacity of the internal battery from zero to 100%. Each LED
indicates approximately 25% of full charge.
