LED Operation
The Output Board uses two onboard LEDs to provide status information during the
power-up sequence and during normal operation.
Table 3: LED Settings
In addition to the status LEDs, there are 16 additional LEDs on board for relay sta-
tus. When any relay is energized or ON, its corresponding status LED turns ON
also. The LED remains ON for as long as the relay is energized. The assignment for
each relay status LED is shown in the following table.
Table 4: Relay LEDs: 0-7
