George,

I have a Bridgeport Interact Series 1 with a Heidenhain TN151 controller. It's unable to start the spindle motor, opening the main power circuit internally every time I try to start it up. I go through the startup routine of clearing the memory check, "Power Interrupted" message, and finding the axis datums. Then I try to start the spindle motor with the upper front panel pushbutton and direction switch. The machine makes a loud click, like a contactor cycling, and it is back at the "Power Interrupted" message. It was working fine at the dealer before it was delivered to my shop. I suspect the problem is with internal power settings similar to the other postings in this thread. Can you send me a wiring diagram for this machine, or advice on what to check?

Thanks!
