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?
Have you used the Test Menu to test the function of the sensors, I believe it is under Test/Sens. You can select each of the pan and tilt sensors and make sure they are working. Sounds like you have a problem with the Tilt or pan stop sensor. If the hubs were not reinstalled correctly this will cause this error. Did you reinstall the hubs with the 2 screws lined up to the marks on the end of the pan and tilt tube? Let us know what the test menu says, and I think we should be able to figure it out.

Yes sensors check out via info/sens on this unit. Yes I noticed the markings and the ones along the tubes too. I'm thinking it might be the harness can't handle a load but still passes continuity test. I am temted at this point to ship it off to have it repaired . I am runing out of time to deal with it. Thanks for taking the time to answer my question .
Encoders work too?.... Hmm, thats a tough one. It really doesn't sound like a wiring issue..... but you never know I suppose.... Sorry I wasn't more help... Josh
I know you said they tested OK, but is there any chance that the pan/tilt homing/stop sensors are reversed? I know I have had days where I have been so close to a problem, that I would miss the minor detail that the pan test was showing good, but I was tilting the head, and vice-versa . . . .
My Studio* fixtures are older, and don't have the encoders, so I do need to ask - is the menu test showing the encoder function, or the homing opto? (Mine are all in the air, so I can't go check . . . ).
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.
