10. Connecting the SystemAfter performing all preliminary tests, prepare and connect the BCT-2000 Series system.10.1. Determine Load TypeThe BCT-2000 System can operate in three different types of load configurations.10.1.1. Optional Load Banks (Battery Isolated)One recommended way to load test a battery is with the battery completely isolated fromthe system or its associated load, using optional Albércorp Load Banks. In this instance,the charger carries the load until the test ends.WARNING: When using this method, if a loss of power occurs during the load test,there will be no battery on line to support designed operation. Before switching thebattery off line from the charger, ensure that design criteria allows for the charger to carryfull load. Some organizations require placing a backup battery into service prior to loadtesting a critical battery.10.1.2. Optional Load Banks (Supplemental Load)A second recommended way to load test a battery is to supplement the service load on thebattery with Albércorp load banks. In this case, the battery is left on line and a capacitytest is performed using the load bank and system load as a combination total load on thebattery. This is done by reading the present load on the battery charger, subtracting thatfrom the discharge load required, and programming the unit for the balance of thetheoretical load.10.1.3. System LoadUsing the system load on the battery allows the system load to be placed directly on thebattery, with the BCT-2000 used as a data gathering device. The BCT system will notread current unless a current shunt is installed and optional current sense leads areconnected to the shunt. (Done as a rundown test on the BCT.)14
