ABSTRACT:
The present invention relates to an electronically adjustable actuator for actuating a plurality of actuating elements, such as valves. A control unit is provided for generating actuating signals to cause each of the valves to move with one another in a start-stop motion in accordance with a predetermined moving pattern. The control unit would measure each potential at the outermost lowest position of the valve and at the outermost highest position of the valve. A device is provided for determining the present potential percentage value of the different valve between the maximum potential as well as the minimum potential. This different value is used to determine whether an actuating signal would be used to drive each of the actuating elements in the start-stop motion.
