1/3ph + 3ph
1-phase + 3-phase, or 3-phase + 3-phase, two-shot reclosing.
The operation is similar to that in program 1/3ph, described above, but at
a tripping after the first reclosing shot, a second reclosing shot is made.

3.1 Recommendations
regarding input
signals
The signals can be configured via the built-in MMI or with the CAP 531
configuration tool.

AR01-ON and AR01-OFF
may be connected to binary inputs for external control.
AR01-START
should be connected to the protection function trip output for which it is to
be started. It can also be connected to a binary input for start from an
external contact. A logical OR gate can be used to multiply the number of
start sources.
AR01-INHIBIT
can be connected to binary inputs, for example for AR blocking from a
certain protection, such as a line connected shunt reactor, transfer trip
receive, or back-up protection or breaker-failure protection.
AR01-CBCLOSED and AR01-CBREADY
must be connected to binary inputs, for pick-up of the breaker signals.
Should the external signal be of Breaker not ready type (uncharged), an
inverter can be configured before CBREADY.
AR01-SYNC
is connected to the synchro-check internal function if needed. It can also be
connected to a binary input. If neither internal nor external synchronism or
energizing check (dead line check) is required, it can be connected to a
permanent 1, by connection to FIXD-ON.
AR01-PLCLOST
can be connected to a binary input, when it is to be used.
