Binary output LEDs

The BO1–BO6 LEDs indicate the status of the six binary outputs.
Table 18 describes binary output LED activity.
Note:
Each binary output LED reflects the status of the output relay on the
circuit board. It may or may not reflect the status of the equipment
the binary output is controlling. Field wiring determines whether the
state of the binary output LED also applies to the status of the end
device. Table 18 describes the LED states.
