Bay type selection defines the external device (DEV01 or DEV02 or ...) that represents the circuit breaker. For the P632, 2 circuit breakers are available. CB1 is used as an example in the following description.

Coupling between control and protection for the “Closed” position signal is made by the setting at MAIN: Sig. asg. CB1 closed. In the same way coupling between control and protection for the “Open” position signal is made by the setting at MAIN: Sig. asg. CB1 open. As a result, the CB status signal needs to be assigned to a binary signal input only if this coupling is implemented.
