jkh,
To answer your question this is a International 100ST personal Elevator, and has a D100A Cutler Hammer PLC for the Controler.
As far as who governs the elevators in our state (Oklahoma) I have no clue. I have been here for 6 years and have never seen, and asked one of our plant Electricians with 47 years and he has never seen nor heard of anyone inspecting this elevator other then the contractor company doing monthly PM's.
My main question is CAN the door lock switches be wired into the PLC as an input stating that the door is open and the PLC prevent the elevator from moving. Or do they HAVE to be wired in series with the Motor stater contactor.
What is the standerd that you see? Does the controller use the door lock switches or are they mostley wired into a series circuit from door to door and then provide the Neutral to the motor staters coil. If in the series Circuit, you wouldnt be able to tell what door is not closed.
Thanks,
James
