Any resolution here guys? Have the same/slightly different issue with my 3 stop. 1-2 is fine. 1-3 or 2-3. "Oops I'm lost". Photo switch error. Returns to 1st landing. Shuts down.
Sent all boards in to be rebuilt. Just reinstalled them. Same issue. Replaced photo switches. Same issue.. cleaned all reflector vanes. Same issue..
