HI all,

I have a strange issue at one customer installation:
One of the Unity Elite (internal FB4) shows some kind of white "standby" beam. So a low powered white beam.
Behaviour is like this:
- The beam is white (so I can exclude one single channel driver defect)
- The beam is only visible when laser output in Beyond is enabled. Deactivated laser output in Beyond will stop this directly...
- No DMX in signal to Beyond (Cues are fired via GrandMa, but I disabled DMX for root cause finding)
- Emergency switch works.. so the beam dissapears when stop switch is activated
- Reset all live control... did not help
- I tried to completely blank the output by BAM to 0% at full output zone ... did not help
- Projector settings are ok... no change in color settings...
- full restart of laser, Beyond, GrandMa... did not help

Since the hardware seems to be fine, I assume something happened in Beyond (it´s a permanent installation some 100km away, so I can only check via screen remote)

--> Is there any setting in Beyond that might lead to this strange behaviour? Or any idea what else to check? Could it be a FB4 issue?


Thanks for your ideas in advance
