Note:
It is recommended to mask Trip and Close commands from a protection function the
same binary I/O’s, if they operate the same breaker. If for instance, the Close com-
mand of the Control function uses two contacts the auto reclose function should be
masked also to both contacts. See elementary diagrams in the appendix A.
