The autoreclosing function can be inhibited with the INHIBIT_RECL input. By
default, few selected protection function operations are connected to this input. A
control command to the circuit breaker, either local or remote, also blocks the
autoreclosing function via the CBXCBR1-SELECTED signal.
The circuit breaker availability for the autoreclosure 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 binary output X100:PO3, whereas the close
command is connected directly to binary output X100:PO1.
Set the parameters for DARREC1 properly.
Check the initialization signals of the DARREC1.

Figure 459: Autoreclosing function
Two overvoltage and undervoltage protection stages PHPTOV and PHPTUV offer
protection against abnormal phase voltage conditions. A failure in the voltage
measuring circuit is detected by the fuse failure function and the activation is
connected to block undervoltage protection functions to avoid faulty tripping.
