be achieved by the provision of state signals to the machine controls that, by means of comparison with the setpoints , detect deviations (self-checking). Provided the fault diagnostics also provide early

varying grain size, its effect on the filtering result cannot be applied directly to contamination with debris, which has different geometric shapes.

safe position in the case of a failure of the electrical control energy ( Figure V 26 , in this case with a open-centre position for A, B and T).

Squarewave AC signal from 70 to 400 Hz with low amplitude that is superimposed on the DC control voltage as "hum". The dither signal is used on continuously adjustable valves and has the task of placing

different time; Delay element: Timer element, which reflects the change of the input signal over time with a delay; Signal contracting element: Timer element, which contracts the input signals; Signal stretching

pressure" p 1,2 is allowed if differential pressure itself is the measured variable (in accordance with DIN 1314).

without auxiliary energy, which converts an input signal into an with the same physical properties and a value range suitable for the downstream elements. Example: Voltage converter, electrical potentiometer

directional valves . They increase linearly towards a maximum as flow increases and then decrease with a hyperbolic pattern as the switching distance increases ( Figure S 102 ) ( Bernoulli force ).

case of constant flow systems and secondary control of a hydraulic motor (c) in the case of systems with impressed pressure.

development of the single-chip computer and, by implication, the microcontroller have made this possible, with the option to accommodate digital control electronics within the most confined of spaces.
