Standard Features - GE Digital Energy LP 31 Series Product Description

4. STANDARD FEATURES

Automatic (quick) battery test
The LP Series family UPS conducts periodic automatic battery tests to ensure that the batteries and the
wiring are healthy and able to support power failures.
The tests do not cause any interruption in the function of the unit.
Automatic tests are conducted after every 500 operating hours.
A manual battery test can be activated either through an interface kit via the ComConnect Port, or via the
front panel.
Deep battery calibration test
The battery condition can be calibrated by the UPS monitoring software, ensuring accurate autonomy
prediction.
Please refer to the manual of the appropriate monitoring software package for more information.
During a deep battery test the batteries will be discharged until 'battery low' alarm level.
The test will, after a complete recharge, result in new autonomy predictions.
Communications port
ComConnect: 9-pin Sub-D male plug
No-load shutdown
Whenever the load is <2% of the maximum load, and the input is absent for a period exceeding 10
minutes.
If the input voltage is restored, the output will be available again. Standard: activated.
Bypass enable/disable
If you do not want the automatic bypass switch to transfer to bypass, e.g. in situations of very bad or
unstable mains, the bypass switch can be disabled.
Also if the unit is used as a frequency converter the bypass transfer must be disabled and the control knob
of the manual bypass switch must be removed.
Frequency tracking range
The output frequency will follow the bypass frequency within the frequency tracking range (standard ±
2%).
If the bypass frequency is outside these limits, the inverter will run on its internal oscillator, and bypass
transfer is inhibited.
If you want the bypass switch to operate over a wider frequency range (e.g. in case of generator supply),
the tracking range can be changed into ± 4% or ± 6%.
