The hoistway setup and door scan are completely independent…. If you have a successful hoistway scan there’s no reason to do it again to get a door scan to take. To do a door scan, weather it be immediately after a HW scan or later after moving a limit. Car on auto, open the door to the limit, put on inspection, clear the faults, DOR PAR O PRE, STS 1 E, take off inspect, should see SUP so you know the door is in setup mode, let the doors close. Check your new scan value in DOR PAR 1, then DOR PAR 0 SAV.
For the hoistway scan I almost always do it from the machine room with a jumper from INB to INU, bump down off the limit, check that floors have values, SEL PAR 0 SAV. Take it off inspect and it should level in. If it fails I’ll go to the car top to watch the selector LED but it rarely does.
