I responded to a shutdown this morning and found the car at the top landing. Hall calls and car calls latch, doors close but the elevator does not move. Went to the control room, there are no faults. I put the car on inspection and tried to run it down. My locks, gate, safety and direction inputs go high when I try to run in the down direction but the car does not move, I do not get the main contactor to pick. The car does run in the up direction so I am assuming it is the down normal limit that is bad. I didn't find any normal limit switches in the shaftway. Are the normals virtual? Anyone have any advice?
