i have a trackspot that makes an error tone before the devices try to home, all dip switches are off, the colors and gobo do not even turn 1/4 turn that the tones appears, when i disconnect the sensors the color , gobo, pan, tilt it goes onto trying to home (without succes because theres no sensors) so im guessing theres a faulty sensor? i know it worked great before i played with the shutter motor, is it possible that if a wire is cut from a sensor it will do the error tone right away?
