How do I set up the logic on a 311C to block zone2 / zone 3 reclosing AND have it such that if the line comes back live (successful re-close on the remote end) the relay closes the local breaker back in? It looks like you can set the relay to drive-to-lockout on a number of parameters, but nothing on having it re-close after live line/live bus.


For those who ask why you would ever block a zone 2 reclose: I'd like to have it so if the station has a DC outage (or bus protection failure) with a simultaneous bus fault, remote relaying can clear this on zone 2 without all of a suddenly having 12 lines all start reclosing at the remote ends. :eek:
