TECHNICAL DESCRIPTION

The ND9000 is a 4–20 mA or fieldbus powered microcontrollerbased intelligent valve controller. The device contains a Local

User Interface (LUI) enabling local configuration. A PC with FieldCare software can be connected to the ND9000 itself or to the

control loop. 

The powerful 32-bit microcontroller controls the valve position.

The measurements include:

□ Input signal

□ Valve position with contactless sensor

□ Actuator pressures, 2 independent measurements

□ Supply pressure

□ Spool valve position

□ Device temperature

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.
