Jumper on System Interface Board
Perform the following procedure to make the required setting per your site requirements. This procedure can also be used to make
adjustments on a replacement circuit card.
Controller Power Option
This option allows the controller to remain powered if the battery contactor opens. The controller is powered from the internal “system”
bus. Rectifiers and battery are connected to this “system” bus, so the controller is powered both by the rectifiers and by the battery. A
jumper option allows the controller to be powered from the “system side” of the battery contactor or the “battery side” of the battery
contactor. Refer to
for circuit card location.
•
Jumper in “No Battery Power” Position: The controller is powered from the “system side” of the battery contactor. If the
battery contactor opens, the controller is powered by the rectifiers (if functional). This is the default setting.
If you lose AC power and your battery contactor opens, the controller will shut down.
•
Jumper in “Battery Power” Position: The controller is powered from the “battery side” of the battery contactor. If the battery
LVD contactor opens, the controller is powered by the battery and the battery will drain. The controller’s power consumption is
5W.
If you lose AC power and your battery contactor opens, the controller will continue to operate.
