Depending on the program selection and the selected fault types
that start and inhibit reclosing, a check of no unwanted reclosing
can be made. For example, if only single-phase reclosing is select-
ed, a test can verify that there is no reclosing after two-phase and
three-phase trips.

If a multi-breaker arrangement is used for the application and priorities are given for the
master (high) and slave (low) terminals, test that correct operation takes place and that
correct signals are issued. The signals WFMASTER, UNSUC, WAIT and INHIBIT
should be involved.
