1.1 Principle of Operation
TheV200incorporatestheforcebalanceprincipal of operation. The desired value, in theformofpressure,affectsthemembrane(1)with the force that is created and transferred to the balance arm(2). The opposing force, which represents the actual control value, is provided by the feedback spring(5) and creating force in the opposite direction on the balance arm(2).The feedback spring, resting on the feedback arm(3), is positioned by the shape and re-sponse of the cam. The cam(4) is connected to the cylinder’s (actuator) piston rod via the drive. The pilot valve(6) is connected to the balance
arm and follows the balance arm’s movement. The system is stable when the gold plated spool(7) is in the neutral position and the forces thataffectthebalancearmisinequilibrium.As soon as a signal change occurs or a change inthepositionofthevalve/actuatorpackageoccurs, the “force balance” is also changed and the spool responds. Air immediately begins toflowintothepartoftheactuator(C+orC-)which allows the feedback mechanism to return the spool to the neutral position.The system is self-stabilizing and searches for a steady state position.
1.2 Product identification
TheV200identificationtags,Serialnumbertag(1), product model tag(2) and feedback op-tion tags(3), are placed as shown. The product model tag contains information on control signal, maximum working pressure and temperature ranges. Other information can be shown depending on the model.

CAUTION: Beware of moving parts when positioner is operated!
CAUTION: Beware of parts with live voltage!A voltage, which is normally not dangerous, is supplied to the
positioner.Avoid touching live parts and bare wires as well as short circuiting live parts and the housing.
CAUTION: Do not dismantle a pressurized positioner!Dismantling a pressurized positioner will result in uncontrolled pressure release. Always isolate the relevant part of the pipeline. Release the pres-
sure from the positioner and the pip- ing. Failure to do this may result in
damage or personal injury.
CAUTION: Do not exceed the positioner performance limitations!Exceeding the limitations marked on the 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 of premature functional problems with pneumatic and electro pneumatic equipment. The pilot valve and IP-converter are precision instru-ments, and are therefore the most sensitive parts 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-timesfloodsmallwaterseparators.Thisex-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 water separators with adequate capacity. Coales-ingfiltersfromareputablemanufacturerisaninexpensive way to help prevent unit malfunc-tions or failures, and add life to the product. Thesefiltersremoveparticlesandmoisturefrom air lines.
b) Oil in the supply air usually is from the maincompressor. Oil can clog the small nozzlesanddisturbtheflapperintheIP-converter.Itcan also cause the gold plated spool to “drag”within the pilot valve. The result is poor controlor in the worst case, failure.
c) Particles in the air usually occur becauseof corrosion. 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.
ToensurenormaloperationalsafetywithVACpositioner products, we recommend that a wa-terseparatoranda<80micrometerfilteraremounted as close to the product as possible.If large amounts of oil are present an oil sepa-rator should be installed as well.
To further increase operational safety, we rec-ommend that the working air is clean, dry and free of moisture, water, oil, particles and other contaminants, in accordance with the standard ANSI/ISA–7.0.01–1996

2.2.1 Rotary actuator
TheVACV200hasaverystableandproperlysized drive shaft bearing. However, the posi-tioner drive(A) should be aligned properly to the rotary actuator spindle(B). A relatively small error combined with a rigid coupling can create very powerful radialforces, which can overload and cause premature wear.
2.2.2 Linear actuator
When mounting to linear actuators, thepositioner should be attached in such away that its drive is in the center (mid stroke)of the actuator’s stroke. Proper installation and alignment will minimize linearity error.

2.5 Cam
The V200 is standard shipped with the C1-cam, factory set for 90° ±1°, direct (CCW) turning.
2.5.1 Adjustments
Remove the front cover and indicator.(see page 15)
1. Loosen the locking screw(2) and the camnut(1).
2. Strokethevalve/actuatortothestop/endposition at 0% input.
3. Turn the cam(3) so that the index mark(5)for the selected curve aligns with the ballbearing(4). A small gap between the roller andthe cam tip is desirable.
4. Tighten the cam nut by hand(1).Check that the locking screw(2) is still loose.(if not, loosen the locking screw slightly andtighten the nut again).
5. Tighten the locking screw(2).Do not tighten cam nut with screw(2) down.
