The PMV D3 is a digital positioner de-signed primarily to control modulatingvalves.
The positioner can be used with singleor double action actuators with eitherrotary or linear movement.
The D3 can be equipped with modu-les for feedback, limit switches, and apressure gauge block.
The modules can be factory assembledbefore delivery or fitted later.
Safety instructionRead the safety instructions in this manual carefully before using the product.The installation, operation, and maintenance of the product must be done bystaff with the necessary training and experience. If any questions arise duringinstallation, contact the supplier/sales office before continuing work.
Warning• The valve package moves when in operation and can cause personal injury
or damage if handled incorrectly.• If the power supply fails or is turned off, the valve moves quickly to its end
position.• If the compressed air supply fails or is turned off, fast movements can occur.• The valve is not controlled by the input signals when in the Out of service
position. It will open/close in the event of a leak.• If a high value is set for Cut off, fast movements can occur.• When the valve is controlled in the Man mode, the valve can move quickly.• Incorrect settings can cause self-oscillation, which can lead to damage.
ImportantAlways turn off the compressed air supply before removing or disconnectingthe air supply connection or the integral filter. Remove or disconnect withcare because C- is still under pressure even after the air supply is turned off.
The modules for feedback and limitswitches can contain the following:
Feedback 4-20 mA and one of thefollowing functions:
- Two mechanical switches- Two reed switches- Two inductive sensors- Two soft contacts (relays)
1. Introduction

General
The PMV positioner is a precision instru-ment. Therefore it is essential that it ishandled and stored in the correct way.Always follow the instructions below!
NOTE! As soon as the positioner isconnected, an very minimal internal airleakage supply will provide protectionagainst corrosion and prevent the ingressof moisture. For this reason, the airsupply pressure should always be kepton.
Storage indoors
Store the positioner in its originalpackaging. The storage environmentmust be clean, dry, and cool (15 to 26°C,60-80°F).
Storage outdoors or for alonger period
If the positioner must be stored outdoors,it is important that all the cover screwsare tightened and that all connections areproperly sealed.
The unit should be packed with adesiccant (silica gel) in a plastic bag orsimilar, covered with plastic, and notexposed to sunlight, rain, or snow.
This is also applicable for long-termstorage (more than 1 month) and for longtransport by sea.
Storage in a warm place
When the positioner is stored in a warmplace with a high relative humidity andis subjected to daily temperaturevariations, the air inside the unit willexpand and contract.
This means that air from outside theunit may be drawn into the positioner.Depending on the temperaturevariations, relative humidity, and otherfactors, condensation and corrosion canoccur inside the unit, which in turn cangive rise to functional disorders or afailure.

The D3 positioner contains:• electronic board with microprocessor,
HART modem, display etc,• pneumatic valve block,• positional feedback with potentio-
meter,• sealed compartment for electrical
connections.
The pushbuttons and display areaccessible underneath the aluminumcover, which is sealed with an O-ring.
The figure shows the D3 with the coverremoved.

Double action function
The control signal and the feedbackpotentiometer position are converted todigital signals that are processed with aPID algorithm in the microprocessor.This provides control signals to the twopiezo-valves. The two piezo–valves areclosed in the schematic diagram aboveand have no effect on the valves A andD.
Air from the pressure regulator flowsthrough the open valve A to the valve B,which opens. The supply pressure nowthrough valve B to the actuator via H.The actuator then moves in the directionof the arrow. At the same time, air flowfrom valve A keeps valve C open andallows venting of the actuator. When

Single action function
Valve B is used for the supply air andvalve F for venting. The positioner canbe converted from double acting tosingle acting by installing a screw closingH, described on page 36.
By converting to single acting function,damper I is engaged. For double actingfunction the screw should be installed atG, bypassing damper I.

Air supply requirements
Max. air supply pressure, see the sectionTechnical Data on page 39.
The air supply must be free frommoisture, water, oil, and particles.
The air must come from a refrigerationdried supply or be treated in such a waythat its dew point is at least 10°C, 18°Fbelow the lowest expected ambienttemperature.
To ensure a stable and problem-free airsupply, we recommend the installationof a filter/pressure regulator <40µ asclose to the positioner as possible.
Before the air supply is connected to thepositioner, we recommend the hose isopened freely for 2 to 3 minutes to allowany contamination to be blown out.
Direct the air jet into a large paper bagto trap any water, oil, or other foreignmaterials. If this indicates that the airsystem is contaminated, it should beproperly cleaned.
6. Installation
WARNING. Do not direct theopen air jet towards people orobjects because it may causepersonal injury or damage.
Poor air supplies are the main sourceof problems in pneumatic and electro-pneumatic systems.
8
The D3 positioner has an ISO F05footprint, A. The holes are used to attachit to the mounting bracket B, which issuitable for most types of linear actuator.
The spindle adapter C can be changedto suit the actuator in question.
Remove the existing adapter using twoscrewdrivers. Check that the spring ringon the new spindle is undamaged beforeinstalling.

Mounting
NOTE! If the positioner is installedin a hazardous environment, itmust be of a type approved for thispurpose.
It is important that the positioner ’sspindle and the arms, that transfer theactuator movements, are correctlymounted. Any tension between theseparts can cause incorrect operation andabnormal wear.

Removing cover and innercover
• Unscrew the screws A and remove thecover.
• Pull off the disc with the arrow B.
• Unscrew the screws C, pull the innercover slightly in the direction of thearrow, and remove the cover.
When performing service, replacing a circuit board, or other repair, it may benecessary to remove and refit various parts of the positioner. This is described onthe following pages.
Read the Safety Instructions on page 3 before starting work on the positioner.
Cleanliness is essential when working with the positioner. Contamination inthe air ducts will ultimately lead to operational disturbances. Do not disassemblethe unit more than what is described here.
Do not take the valve block apart because its function will be impaired.
When working with the D3 positioner, the work place must be equipped withESD protection before the work is started. Always turn off the air and electricalsupplies before starting any work.

Valve block
Turn off the air and electric powersupply before starting any work.
• Disconnect connector F from the pro-cessor pcb.
• Remove the four screws I.
• Lift out the valve block
NOTE! Do not disassemble the valveblock. Will not operate if opened.
Single/Double action
• The D3 can easily be converted fromdouble acting to single acting or viceversa by moving screw J as shown.
For single action, screw should be placedinto the bottom of the housing.
For double action, screw should beplaced into the lower side of the valveblock. Factory default setting.

Potentiometer
The spring-loaded potentiometer K canbe removed from the gearwheel forcalibration or replacement.
If the potentiometer is replaced or thesetting is changed, it must be calibratedin the menu Tuning - Expert - Ref cal pot.
Spindle adapter
The spindle adapter L can be changed tosuit the actuator in question.
• Remove the existing adapter using twoscrewdrivers. Check that the springring on the positioner’s spindle isundamaged. Fit the new spindle.
Filter change
Turn off the compressed air supplybefore starting any work.Otherwise the filter can beuncontrollably blown out of thepositioner by the air pressure,which can be dangerous.
• Unscrew the filter with a coin orsimilar.

Fault symptom
Change in input signal to positioner doesnot affect actuator position.
Change in input signal to positioner ma-kes actuator move to its end position.
Inaccurate regulation.
Slow movements, unstable regulation.
Action
• Check air supply pressure, aircleanliness, and connection betweenpositioner and actuator.
• Check input signal to positioner.
• Check mounting and connections ofpositioner and actuator.
• Check input signal.
• Check mounting and connections ofpositioner and actuator.
• Implement auto-tuning. Check forany leaks.
• Uneven air supply pressure.• Uneven input signal.• Wrong size of actuator being used.• High friction in actuator/valve
package.• Excess play in actuator/valve
package.• Excess play in mounting of positio-
ner on actuator.• Dirty/humid supply air
• Implement auto-tuning.• Adjust the pressure adjusting screws.• Increase the deadband (Tuning
menu)• Reduce Performance (Calibrate
