I think the access down limit is actuated by a programmable dpp count relative to the top floor position count. Im wondering if this may be a software problem relating to going past the access limit dpp count and not wanting to run from hoistway key switch because of the count? Have you tried accessing car from hall until it stops, and then mark position on tape, then go down on cartop inspect and return to the mark or a little higher? then try the hoistway key switch. just a thought
