My problem started about 3 months ago. I get a call that the dual light in one of my OR rooms is acting funny. When the light powers on it starts in the number 3 intensity, then after a couple seconds it jumps both touch pads back to 0. Once it does it the first time and you put it on the desired intensity level, it stays until the power is cycled again. So 3 months when trouble shooting I noticed if I unplugged the #1 light from the shared board, the #2 light started working like it was supposed to. I changed both boards and finally found the touch pad on the #1 light was causing the issue, but I’m still not sure how. It worked fine for 3 months. Now the #1 light has started doing the same thing again. I replaced both boards and touch pad with no results. I’m wondering if anyone else has I countered this problem as tech support says they have not. Thanks for any help.

You are describing a grounding problem or digital ground reference. Many commands are done by shorting the digital pin to ground. It sounds like your digital ground is intermittently floating so when a pin should be zero, its actually high. Movements of the light heads could cause a good ground to go in and out. Check your grounds as you move the light heads around.
