Hi, I need some information on the door interlock. I have a machine at work that will not release the door. At power up it should be open but it is not getting power from the controller.I have 24VDC on the N24B-1 and P24-5 wires (located in the interlock device) to operate the switch but across the P24-5 and BT201-6 wires I have 0.00VDC that operate the coil to release the door it wont send back a voltage to release the door. The door remains locked even with the machine in manual mode. Is this a problem with the controller? Does anyone know if I can get the schematics for this?
Has anyone seen this problem?

Thanks,
