Peele freight doors (relays, no solid state). Great question. I don't think the retiring cam is pulling in when we put in a call or try to run on machine room inspection as the Peele door controller is silent (no relays energizing, or at least none that I could hear).

The mechanic I was with claimed the retiring cam was pulling in when we pushed in a relay on the Peele door. We didn't actually verify from the car though.
