Advanced self-diagnostics guarantees that all measurements
operate correctly. After connections of electric signal and pneumatic supply, the micro controller (μC) reads the input signal,
position sensor (α), pressure sensors (Ps, P1, P2) and spool position sensor (SPS). A difference between input signal and position
sensor (α) measurement is detected by control algorithm inside
the μC. The μC calculates a new value for prestage (PR) coil current based on the information from the input signal and from the
sensors. The changed current to the PR changes the pilot pressure to the spool valve. Reduced pilot pressure moves the spool
and the actuator pressures change accordingly. The spool opens
the flow to the driving side of the double diaphragm actuator and
opens the flow out from the other side of the actuator. The
increasing pressure will move the diaphragm piston. The actuator
and feedback shaft rotate. The position sensor (α) measures the
rotation for the μC. The μC using control algorithm modulates the
PR-current from the steady state value until the new position of
the actuator, according to the input signal, is reached.
