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.
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 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 output can be evaluated without disrupting
critical operations. The experiment should last long enough to assure that all expected line conditions are
encountered.
