LED Operation
The Input Board uses two onboard LEDs (D1 and D2) to provide status information
during the power-up sequence as well as during normal operation.
In addition to the status LEDs, there are two additional relay status LEDs and 16 input
status LEDs on board. The input LEDs flash when there is an alarm associated with
the input. When any relay or input is energized or ON, its corresponding status LED
becomes ON also. The LED remains ON for as long as the relay is energized.
