American Power Conversion 2200 manual Voltage Sensitivity, Low Battery Warning Interval

5.9 Voltage Sensitivity

The unit detects line voltage distortions such as spikes, notches, dips, and swells, as well as distor- tions caused by operation with inexpensive fuel powered generators. By default, the unit reacts to distortions by transferring to on-battery operation to protect the loads. Where power quality is poor, the unit may frequently transfer to on-battery operation. If the loads can operate normally under such conditions, battery capacity and service life may be conserved by reducing the sensitivity of the unit.

To reduce unit’s sensitivity, press the configuration button on the rear panel. Use a pointed object such as a pen to press the button. Press it once to set the unit’s sensitivity to reduced. Press it again to set the sensitivity to low. Press the button again to reset normal sensitivity.

When the unit is set to normal sensitivity, the configuration LED is brightly lit. When it is set to re- duced sensitivity, the LED is dimly lit. When it is set to low sensitivity, the LED is off.

5.10 Low Battery Warning Interval

By default, the low battery warning occurs when there are approximately two minutes of on-bat- tery run time remaining. This may not be enough time to gracefully shut down some protected computer systems. To change the warning interval, press the rear panel configuration button while pressing and holding the front-panel on/test button. Use a pointed object such as a pen to press the configuration button.

Press the configuration button once to set the low battery warning interval to approximately five minutes. Press it again to set the interval to approximately seven minutes. Press the button again to reset the interval to two minutes.
