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.
Basic Operation
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. 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 may be evaluated without disrupting
critical operations. The experiment should last long enough to assure that all expected line conditions are
encountered.
Tap the
button repeatedly to advance to Sensitivity display, as shown on the previous page.
Press the
button to advance through the options. The last option displayed before navigating
away from this menu option will be the selected setting.
Factory Mode Reset
The LCD settings can be restored to Factory Mode by holding the MODE and ENTER/MUTE buttons
simultaneously for 5 seconds while in any display mode.
CAUTION: This action cannot be undone.
