We have a DMC-1 with electronic door protection and after being held opened for 20 sec it closes on nudging. Should or can the door open button reopen the door when closing on nudging. When the door open button is pressed the door stops but will not reopen. The detector is connected to the electronic eye connection and the safety edge connections are jumped. We did reverse these connections and the door goes into nudging but will not close while the detector beam is broken. Thanks
