Abstract

An example control unit may include: a processor; an output device; a valve element; an actuator; and a sensor for the position of the valve element. The valve cycles and the processor records a first signal to measure a position of the valve element. The valve cycles and the processor records a second signal to measure a position of the valve element. The processor calculates a degree of wear based on the first value and the second value and the second number of valve cycles. The processor compares the degree of wear to a predefined threshold value and generates an output signal if the degree of wear exceeds the predefined threshold value.
