Overview
Function
Circuit boards (sometimes referred to as “cards”) are included in the battery
connection and dc distribution panels to provide data to the controller.
Terminal Boards
Terminal boards are used to provide shunt voltage data to the controller, where
it is used to calculate current. Terminal boards located on the battery connection
panels provide data that is used to calculate battery current; data from terminal
boards located on the dc distribution panels is used to calculate load current.
Alarm Boards
Alarm boards perform two functions:
•
monitor panel functions and activate local indicators when faults occur on
the panel
•
provide alarm data to the controller
Alarm/Terminal Boards
Alarm/terminal boards combine the functions of alarm boards and terminal
boards.
BLJ Terminal Board
The BLJ terminal board is located inside the cabinet door. The BLJ is the
termination point for all signal cables in each cabinet and between cabinets.
