hey there. ive been having issues with a 6 stop dover mp1. it seems that only in the down direction the car will drop the "R" contactor momentarily just above or around the 6th landing on multi floor runs, will "lose" itself when sent to the 6th landing and works fine on single floor runs to that landing. ive changed the floor magnet, LS1, WP, WR, WM, IFA and the 2F cards. it does not happen in the up direction or on any other floors. I have been getting no elevation faults on the wm card. Any thoughts? thanks in advance.
