We are seeing the error 1783. I have read quite a few threads regarding this. Stumped. I switched out the solenoid to see if that was failing. Same result. I have the turret cover removed. It's clean inside that area. No oil dripping or leaks. The proximity switches both light for unclamp and clamped.
When the alarm pops, the proximity switch lights will both be off and the plate that triggers is about in the middle between them.

Any ideas?
