ON Battery Events
This feature allows the user to view the number of times the UPS has experienced an ON
Battery Event. To reset the counter to “0,” press and hold the button.
Basic Operation
Tap the button repeatedly to advance to the ON Battery Events display, as shown above.
Note: The value displayed is a random value used for example reference.
AVR Events
This feature allows the user to view the number of times the UPS has experienced an
Automatic Voltage Regulation Event. To reset the counter to “0,” press and hold the
button.
Tap the
button repeatedly to advance to the AVR display, as shown above.
Note: The value displayed is a random value used for example reference.
Power Sensitivity
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 pure 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 ensure that all expected line
conditions are encountered.
