Hello colleagues I got a work ray team which precedes a failure when the head moves. It is an intermittent beep, there to turn it off so that the fault comes out. finally check the plate which is fine. disconnect the head to see if it was the problem, which now arises the doubt, to disconnect the head throws that fault. when I connect it, not when we move the head to all sides, which I said was the cable, but what I can't understand is that the fault appears with the head disconnected. if the head does not energize until the moment of firing. It's a good idea I listen to opinions, greetings
