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.
