Basic Operation
6
LCD Brightness
Tap the
MODE
button repeatedly to advance to the LCD Brightness screen marked “LCD”. Press
the
MUTE
button to select Medium Backlight (default), High Backlight or Dim Backlight. The last
option displayed before navigating away from this menu option will be the selected setting.
Note: After 2 minutes of inactivity, the backlight will revert to the Dim setting until a button is pressed.
Self-test
Tap the
MODE
button repeatedly to advance to the TEST BATT screen. Press the
MUTE
button to
initiate the test. The test will last approximately 10 seconds as the UPS switches to battery to
test the capacity with a load. Upon completion of the test, the screen will indicate PAS or
BAD (pass or bad) for 20 seconds, then return to the home screen. Connected equipment
can remain on during the test. Do not unplug your UPS, this will remove safe electrical
grounding.
Power Sensitivity
Tap the
MODE
button repeatedly to advance to Sensitivity screen, as shown here:
Press the
MUTE
button to advance through the options. The last option displayed, before
navigating away from this menu option, will be the selected setting.
This setting is normally set to 100%, which enables the UPS to protect against waveform
distortions in its AC input. When such distortion occurs, the UPS will normally switch to
providing PWM sine wave power from its battery reserves for as long as the distortion is
present. In some areas with poor utility power or where the UPS’s input power comes from a
backup generator, frequent brownouts and/or chronic waveform distortion could cause the
UPS to switch to battery too often, draining its battery reserves. You may be able to reduce
how often your UPS switches to battery due to waveform distortion or brownouts by
experimenting with different settings. As the setting is reduced, the UPS becomes more
tolerant of variations in its input power’s AC waveform.
Note: When experimenting with different settings, operate connected equipment in a safe test mode so
that the effect on the equipment of any waveform distortions in the UPS’s output can be evaluated
without disrupting critical operations. The experiment should last long enough to assure that all expected
line conditions are encountered.
