Old Dover Door Issue - 01/03/19 02:50 AM
Have an old relay logic Dover that as soon as you go to Auto the doors open. OD is not picked, SE is picked. There was vandalism to the doors including off the tracks, but have fixed all that, but this problem persists. Any help or suggestions would be appreciated.
Prints attached.

If the door opeerator circuit (line 329-339) is correct, there is a front and a rear door. Is this the case? OD will drop after the doors open and hit either Door Open Limit. Are you saying that the doors opened without DO, or that the doors opened when you put the mainline in? When SE falls, the doors should close.

Yeah, the doors are opening without OD. And SE is staying picked.

Danzeitz is correct. Had this one many times.

Wow, I have never seen front and rear door operators drawn together like that. It looks like the first one to get to DOL wins.

That was a first thought, but the print doesnt show any orange drop caps. I've worked for Dover distributors for 30 years and never saw one without them, but they were always on the prints.
