I Have a studio color 575 with a pan stop error . The fixture would go to full pan position , slam against stops and make a load racket trying to go farther . I tried cross testing ( put them in another fixture to test them. ) both the power supply boards , motor , sensor , and the logic board . I also confirmed it was set to studio color and not studio spot. I did a continuity test on the harness that’s involved. All checked out fine. Still had the problem . I tore this light all the way down and replaced the bearings in pan and tilt . I also replaced the motors and sensors . Now I had the same problem with pan and tilt . I triple checked to make sure I plugged it all back in correctly , rechecked the harness for continuity , cross checked motors to make sure the new ones were the correct ones , and waved a sledge hammer in a threatening manner . Still have pan and tilt slamming against stops and making horrible noises .at a loss. What I miss ? Where did I go wrong with this fixture?
I tested the encoders when I swapped out the motors . I just switched the motor mounts to make it quicker. The encoders are attached to the mount with the motor. Josh was correct , the wires passed load test . I know it’s something simple I’m missing . I needed some parts for other lights so I stole it’s motor power supply card for another fixture . So I will have to put off trouble shooting it for a bit . I will let you know what it was when I figure it out though . I have fixed allot of these fixtures but haven’t seen this before.
