The circuit breaker availability for the autoreclosing sequence is expressed with the
CB_READY input in DARREC1. The signal, and other required signals, are connected
to the CB spring charged binary inputs in this configuration. The open command from
the autorecloser is connected directly to the binary output X100:PO3, whereas the
close command is connected directly to the binary output X100:PO1.

The residual overvoltage protection ROVPTOV provides earth-fault protection by
detecting an abnormal level of residual voltage. This can be used, for example, as a
nonselective backup protection for the selective directional earth-fault functionality.
