Thanks so much for reply. I obviously didn't explain well. You are correct in your first assumption of my analysis --- the car will run all day in hoistway between 1-5. It will stop at 6 or 7 for a hall or car call then it will NOT come back down from 6 or 7. It will go up from 6 TO 7 but will not come down from 6 or 7 to any of the lower floors. All calls latch from lower floors or inside car, but the car will not move. Probably not a door problem since it will go from 6 to 7 (will go up).
