I have a Dover hydro with IBM wire contact relays that runs from 1st floor to 2nd floor non-stop. SU is in while running up, and as soon as it hits the door zone at floor 2, SD pulls, which brings in the down pilot, and once the doors finish their cycle, the car runs down. As soon as it hits door zone at floor 1, SU pulls...
According to the print, 1C, 2C, TC, 2U, 1U, or 2D normally open contacts would need to pull for SU or SD to be able to pull. None of these relays are pulling, and none of the contacts are welded or stuck.
It's almost as if the elevator is searching for a ghost floor in between 1 & 2.
I'm at my wits end. I've been on this thing for over 2 days now and I'm getting nowhere. Please help if you can.
Thanks!
