4.10.2 Automatic Operation. Elevator operation shall be automatic. Each car shall be equipped with a self leveling feature that will automatically bring the car to floor landings within a tolerance of 1/2 in (13 mm) under rated loading to zero loading conditions. This self leveling feature shall be automatic and independent of the operating device and shall correct the overtravel or undertravel.
