2.10.3 Autoreclose Output Signals

The autoreclose scheme logic has two output reclosing signals: ARC1 and ARC2. ARC1 is a
reclosing signal for single breaker autoreclose or a reclosing signal for the busbar breaker in a
two-breaker autoreclose scheme.

ARC2 is the reclosing signal for the center breaker of the two-breaker autoreclose scheme.

The assignment of these reclosing signals to the output relays can be configured, which is done
using the setting menu. For details, see Section 3.2.2. For the default setting, see Appendix D.
