Power Sensitivity
Tap the
MODE
button repeatedly to advance to Sensitivity display, 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.
Scroll Control
Tap the
MODE
button repeatedly to advance to the Scroll display as shown here:
Press the
MUTE
button to advance to the next available option. The last option displayed, before
navigating away from this menu option, will be the selected setting.
This display option allows the user to select the option to automatically scroll each operating
condition of the UPS (such as Input Voltage, Output Voltage and Runtime) automatically.
NOTE:
1. Each condition is displayed in 2 second intervals.
2. If a button is pressed while Scroll Mode is enabled, the scroll function will pause for 10 seconds to allow the
user to manually make menu selections.
