Perform a Parallel Battery SPoT Mode Test in a Parallel UPS System
Prerequisites for each UPS in the parallel system:
-
All UPSs in the parallel system must have the same power rating and the same available power
-
UOB must be open
-
The UPS operation mode for each UPS in the parallel system must be Requested static bypass
-
The system operation mode for the parallel system must be Requested static bypass
-
The battery disconnect device(s) BB must be closed
-
There must be no detected surveillance faults
-
SSIB must be closed
-
The output voltage and frequency must be within the predefined limits
This feature performs a battery discharge test without the need for a load bank. During the battery SPoT mode test, the inverter is turned ON while the parallel UPS system is in requested static bypass. During the test, the parallel UPS system performs a battery runtime calibration test and adjusts the estimated runtime accordingly.
The output power can be manually adjusted from 0 to 100% load to be as close as possible to the operating conditions.
The test stops when the battery voltage has reached its shutdown level, or when the predefined discharge level has been reached.
- From the home screen on the display select .
- On page 1 of the menu for Parallel battery SPoT mode, verify that the prerequisites for performing a test is met and confirm that the load is powered if UOB is open during this procedure. Tap the arrow symbol to go to the next page.
- On page 2, follow the listed checklist. Tap the arrow symbol to go to the next page.
- On page 3, set the battery discharge level and the output
power level. Tap the arrow symbol to go to the next page.
- On page 4, tap Start parallel battery SPoT mode to start the test.
NOTE: If you wish to manually stop the test, tap Abort parallel battery SPoT mode.
