Hello all!

I’m in Alaska working on an old Otis that has had a pana 40 upgrade in the past. The problem now is that the light curtain is active in phase 1 fire service (car doesn’t have phase 2). I can easily use a pair of unused contacts on the HEO relay to disable the light ray on fire service but the doors will close at high speed with too much kinetic energy. This car doesn’t have nudging either. I’m haveing a problem figuring out how it originally worked, I’m guessing the safe edge remained active at all times? Am I going to have to use some contacts in the HEO relay to keep the door out of high speed?
I do have prints for this elevator. And help is greatly appreciated.

Joe
