We're having a similar problem with our optical sensors, and maybe someone can help out.

One of the sensors worked fine, the second would always trigger regardless. A short was detected in the wiring and we re-wired it. Now, on the offending sensor, the green "I got it" light flickers constantly, and none of the sensors trigger switch LEDs on the operator interface anymore.

I tried adjusting the gain control on the sensor to no avail. I suspect we may have blown the sensor due to the short, but why are there no LEDs on the OI anymore? I will try swapping the sensors on the wiring.
