ETA SYSTEMS - UNINTERRUPTIBLE POWER MANAGER
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 5-segment LED display that shows the current load percentage. The first four LEDs
each indicate approximately 20% load. When illuminated, the final LED indicates that your connected
equipment is consuming 110% of the UPM rated capacity.
Battery Charge Monitor
The Battery Charge Monitor is a 5-segment LED display that shows the charge capacity of the internal
battery from zero to 100%. Each LED indicates approximately 20% of full charge.
Status Monitor
The status monitor is a row of six individual LEDs that each indicate the status of a part of your UPM
system. The first three LED's work with 's Voltage Manager. All six LED's are explained in the following
table.
LED 1
Voltage Manager Boost Mode: When this LED is illuminated, Voltage Manager has detected that
a low voltage condition exists, and it is compensating by increasing voltage to the UPM input to
the correct level.
LED 2
Voltage Manager Normal Mode: Voltage Manager has determined that input line voltage is
normal and within parameters. No adjustment is necessary.
LED 3
Voltage Manager Buck Mode: When this LED is illuminated, Voltage Manager has detected that
an overvoltage condition exists, and it is compensating by reducing voltage to the UPM input to
the correct level.
LED 4
Battery Mode: When this LED is illuminated, either commercial AC power has been lost or the
UPM has been put into self-test using the Test/Silence button. In Battery Mode, the UPM is
operating on its internal batteries. This LED will remain illuminated until the self-test is completed
