5.11 Setting the Battery Test
A software-controlled battery facility can be initiated from the Operator control Panel
on an ‘immediate’ or ‘periodic’ basis. This test turns off the rectifier and runs the
inverter (and load) from the battery from the predetermined period. If the battery
voltage falls below an preset minimum level prior to the termination of the test period
a ‘BATTERY TEST FAILED’ alarm is annunciated and the rectifier is immediately turned
on to prevent the load from transferring to bypass – and recharge the battery. These
instructions given below initiates an immediate battery test.
For the following test to be ‘meaningful’ as part of the UPS commissioning procedure,
the batteries should be fully charges prior to the test being carried out. The UPS
rectifier section must be therefore allowed to be operated with the battery connected
for several hours to provide the battery with an adequate initial charge.
CAUTION
Do not continue with this procedure if the battery is not yet charged.
