1 INTRODUCTION
1.1 Principle of operation
The V200 feedback options allows for accurate
positionfeedback,whereon-o󰀨(open/closed)
indication(switches)orcontinuous4-20mA
transmission(orsimplepotentiometer)isrequired.
Anyfeedbackmodulecanbefactoryoreldinstalled
inside the V200 positioner housing with no special
parts or mounting brackets. This creates a very
compact and simple package that is completely
sealed.
The various feedback options are connected to the
positionermaindriveshaft(1)whichisconnectedto
the actuator shaft via the positioner spindle, assisting
inamoredirectandaccurateactuator/valvemonitoring.
A position change moves the V200 spindle and switch
cam(2)foron-o󰀨(oropen/closed)indication.
The4-20mApositiontransmittermkII(3)respondsto
changesproportionallyintheactuator/valvepackage.
It is recommended that the V200 positioner be
calibrated before installing feedback options.
CAUTION:
Beware of moving parts
when positioner is operated!
1.3 Safety instruction
CAUTION: Beware of parts with live voltage!
A voltage, which is normally not dangerous, is supplied to the positioner. Avoid touch-
ing live parts and bare wires as well as short circuiting live parts and the housing.
1.2 Product identication
TheV200identicationtags,Serialnumbertag(1),product-
modeltag(2)andfeedbackoptiontag(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.
Not for use in Hazardous locations.
Feedback options described in this manual
are for for General purpose only.

2.2 Front cover and indicator
2.2.1 Removing the front cover
Loosenthetwoscrews(1)and
remove the front cover.
2.2.2 Removing the indicator
Pulltheindicator(2)straightup,itisafrictiont.
Important Note!
Note the indicator’s position so it
can be installed in the same position.
Installing the indicator
Install the indicator in place over the drive
shaft and press it straight down.
Be sure to press the indicator completely down
so that it does not interfere with the indicator
cover(clearcover).
Turn the indicator to the proper display
position.

2.3 4-20mA transmitter installation
2.3.1 Gearwheel installation
1. Remove the front cover and indicator
 ontheV200positioner.(seepage4)
2.RemoveIndicatorscrew(1).
3.Installthegearwheel(2)sothatitalignsover
 thecamlockingnutscrew(3).
4. Secure the gearwheel with the
 Indicatorscrew(1).
2.3.2 Potentiometer installation
1.Installthepotentiometermodule(4)in
the designed section of the unit as
shown. Tighten the screw that secures
the pot arm and spring.
The pot gearwheel should be aligned
and secured to the larger gearwheel.
2.Installthepotentiometerboard(5)orthe
 4-20mAtransmittermodule(6)intothe
designed position and tighten the respective
screws.
3. When used for the 4-20mA feedback, secure
 thepotentiometerconnector(7)tothe
 transmitter(6).Forpotentiometeruseonly,
 theconnector(7)willattachtotheterminal 
 block(5)andbeusedwithanexternalposition
transmitter.

2.3.3 4-20mA transmitter setup
1. Determine the direction for
 increasingmAoutput.Direct(CCW)
 orReverse(CW).
2. The direction of rotation is simply
determined by watching the positioner
 driveshaft(1).
3. CCW rotation: the potentiometer lead
 connector(2)ttedwiththeBlackorBlue
colored lead facing to the left.
4. CW rotation: the potentiometer lead
 connector(2)ttedwiththeBlackorBlue
colored lead facing to the right.
The position transmitter can be calibrated in a
range from 25° up to 115°.
25°-70°withJumper(3).
70°-115°noJumper(3).
The Position Transmitter is
shipped for direct (CCW)
turning, range 0-90°
2.3.4 Connecting the control signal
1. Connect the signal cable to the proper
 poleontheterminalblock(1).

1. Power up the current loop.
2.Connectalowohmicamperemeteroverthetestpoints(5).
3.Setthevalve/actuatortotheclosed/zeroposition(4mA).
4.Turnthefeedbackpotentiometershaft(6)with
a screw driver until you read 3.7 - 3.9 mA on the meter.
5.Adjustthetrimpotentiometer(7)markedzero
so that the meter reads 4mA.
6.Setthevalve/actuatortotheopenposition(20mA).
7.Adjustthetrimpotentiometer(8)marked
span until the meter reads 20mA.
8.Re-checkthezeroposition(4mA)and
 makeneadjustmentsifnecessary.
A very basic calibration can be accomplished
without a meter, using the two LED’s.
Red LED lights up below 3.9mA, Green LED lights up above 20.1mA.
