Hi Alex really like your posts seem to be on point,had a fault with a Schindler 3300 would just park open soon as you break the light curtain would go then park at next floor door open soon as you walk out car break the beam door would shut,so if you ran car from inside would go to floor and stay there until break the beam,seems a simple fault but turns out to be edges as you pointed out in one of your posts ,but could easily be looking at something else,hope this heps anybody out there with similar faults #change the light curtains 😅
