Yeah, Scott, I think you're right about the DOL probably not being "it", because there's no door time. I was thinking that too, but you gotta start somewhere...

But if the door zone went low, then the doors would shut right away, w/o pausing for door time.

Does this job have vanes and mag switches for door zone, or a tape reader? Once I saw a car with vanes, where when the doors were opening, the car doors shifted enough weight from one side to the other, that the cab moved away from the vane, and door zone would dissapear during the door cycle.
