Home Forums General Discussion Technical Questions MiProm 1 with freight doors help

I have a this 3 stop Mipron1 with freight doors. I don’t have a job print or a tool.
It will respond to one call, pick the RC and run to the floor normally but when it gets to the floor the doors don’t open.
From that point the car is out of service. If I cycle power it will do the same.
I will get the RC output but never the door open or door or if I manually open the door, no door close outputs. I assume there is something it doesn’t like or it doesn’t like that the doors didn’t open.

Any input would be appreciated

Send me the WD number from the controller and I'll see if I have something.

Are the freight doors Courion? If so, check the door controller. The relays will hang in with residual magnetism.

In order for GP or Dp to pull in it has to see the door unlocked circuit open. That contact opens when the retiring cam, releases the pick up roller. Of course....the Miprom has to send out the DO signal first. If you still need prints let me know.
