Abstract: A remote adjustment mechanism for the louvered cleaning elements of a combine harvester has a linearly movable output member directly fastened to the adjusting bar of each element. The actuator is driven by an electric motor. Calibration and feedback of the louver opening is provided by a pair of non-contact sensors sealed in the actuator housing. A first sensor sends a signal to a microprocessor controller when the output member is in a home position corresponding to a known louver opening. The second sensor sends a signal to the microprocessor that is responsive to movement of the output member. By tracking the movement of the output member from the home position, the current position of the output member is known from which the louver opening is determined based on the louver geometry.
