    1.1 Principal of Operation

    The V200 incorporates the force balance prin-cipal of operation. The desired value, in theform of pressure, affects the membrane(1)withthe force that is created and transferred to thebalance arm(2). The opposing force, whichrepresents the actual control value, is providedby the feedback spring(5) and creating force inthe opposite direction on the balance arm(2).The feedback spring, resting on the feedbackarm(3), is positioned by the shape and re-sponse of the cam. The cam(4) is connected tothe cylinders (actuator) piston rod via the drive.The pilot valve(6) is connected to the balancearm and follows the balance arms movement.

    The system is stable when the spool(7) is in theneutral position and the forces that affect thebalance arm is in equilibrium.As soon as a signal change occurs or a changein the position of the valve/actuator packageoccurs, the force balance is also changed andthe spool responds. Air immediately begins toflow into the part of the actuator (C+ or C-) whichallows the feedback mechanism to return thespool to the neutral position.The system is self-stabilizing and searches for asteady state position.

    1.2 Product identification

    The V200 identification tags, Serial numbertag(1), product model tag(2) and feedbackoption tag(3), are placed as shown.The product model tag contains information oncontrol signal, maximum working pressure andtemperature ranges. Other information can beshown depending on the model.

    CAUTION: Beware of moving partswhen positioner is operated!

    CAUTION: Beware of parts withlive voltage!A voltage, which is normally notdangerous, is supplied to thepositioner.Avoid touching live parts and barewires as well as short circuiting liveparts and the housing.

    CAUTION: Do not dismantle apressurized positioner!Dismantling a pressurized positionerwill result in uncontrolled pressurerelease. Always isolate the relevantpart of the pipeline. Release the pres-sure from the positioner and the pip-ing. Failure to do this may result indamage or personal injury.

    CAUTION: Do not exceed thepositioner performance limitations!Exceeding the limitations marked onthe positioner may cause damage tothe positioner, actuator and valve.Damage or personal injury may result.

    1.3 Air quality recommendations

    Poor air quality is one of the main causes ofpremature functional problems with pneumaticand electro pneumatic equipment. The pilotvalve and IP-converter are precision instru-ments, and are therefore the most sensitiveparts of the positioner.

    a) Water in the supply air is a natural occur-rence. This happens when air is compressed.The compression heats the air and the naturaldegree of water in the air can remain as mois-ture. When the air cools in pipes etc.the moisture condenses and becomes liquidwater. Large quantities can build and some-times flood small water separators. This ex-cess water will eventually reach the controlvalve and positioner. This can cause corrosiondamage to the IP converter, causing theunit to malfunction.

    We strongly recommend the use of waterseparators with adequate capacity. Coalesingfilters from a reputable manufacturer is aninexpensive way to help prevent unit malfunc-tions or failures, and add life to the product.These filters remove particles and moisturefrom air lines.

    b) Oil in the supply air usually is from the maincompressor. Oil can clog the small nozzles anddisturb the flapper in the IP-converter. It canalso cause the spool to drag within the pilotvalve. The result is poor control or in the worstcase, failure.

    c) Particles in the air usually occur because ofcorrosion. Dirt and particles can block thesmall nozzles of the IP-converter.They can also cause the pilot valve to mal-function. The unit may completely fail.

    To ensure normal operational safety with VACpositioner products, we recommend that awater separator and a
