Operation of the Battery (BA01) Signal Board
The battery signal board contains a red LED that provides the customer a visual indication of
the battery health. An Illuminated LED indicates a battery low condition.
The CPU automatically performs the RTC swap-over, battery test, and battery health LED
operation, whether or not the System block contains a configuration for the signal board.
The battery signal board System block configuration contains selections that allow the
customer to report the battery low state as a diagnostic alarm and/or to report the battery
state (1=battery low, 0 = battery OK) in the LSB of the configured image register input byte
for the device (for example, I7.0). The customer must select the battery signal board in the
System block configuration in order to gain access to the additional battery health reporting
options.
