This is a relay logic Dover selective collective with 4 stops inline. The old IBM relay controls. The car responds properly to the hall calls. But when more then one car call is put in the car skips the first call and stops at the furthest car call out.
So if I have the car at the bottom landing and I place a 2nd and 3rd landing car call the car skips the 2nd and then stops at the 3rd. The selector is stepping in its proper sequence. When 2a1 and 2a2 pickup 2c cancels and the car goes to 3. 3a1and 3a2 pick, CC picks, CS picks and the car comes to a stop.
We are going back on Monday and I would appreciate anything you can share. We do have prints. And it seems that what ever picks and drops CC happens too quickly. And CC doesn't have enough time to pick when there is more then one car call.
