Our FS code is the same function. In this case the elevator recalls fine on phase I to the primary recall floor. Then when switched to Phase II, the doors will close with constant pressure on DCB. Upon arrival to the selected floor the door should open if constant pressure is held on DOB. This elevator's door only opens 1" and immediately re-closes with constant pressure on DOB. It basically traps you in the car because the door pressure to open manually is quite strong. The only way to reset the car is to bring it back to the recall floor and open the doors manually.
