1. Introduction
The PMV D3 is a digital positioner designed primarily to control modulating
valves.
The positioner can be used with single
or double action actuators with either
rotary or linear movement.
The D3 can be equipped with modules for feedback, limit switches, and a
pressure gauge block.
The modules can be factory assembled
before delivery or fitted later.
The modules for feedback and limit
switches can contain the following:
Feedback 4-20 mA and one of the
following functions:
- Two mechanical switches
- Two reed switches
- Two inductive sensors
- Two soft contacts (relays)
Safety instruction
Read the safety instructions in this manual carefully before using the product.
The installation, operation, and maintenance of the product must be done by
staff with the necessary training and experience. If any questions arise during
installation, 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.
Important
Always turn off the compressed air supply before removing or disconnecting
the air supply connection or the integral filter. Remove or disconnect with
care because C- is still under pressure even after the air supply is turned off.
3
2. Storage
General
The PMV positioner is a precision instrument. Therefore it is essential that it is
handled and stored in the correct way.
Always follow the instructions below!
NOTE! As soon as the positioner is
connected, an very minimal internal air
leakage supply will provide protection
against corrosion and prevent the ingress
of moisture. For this reason, the air
supply pressure should always be kept
on.
Storage indoors
Store the positioner in its original
packaging. The storage environment
must be clean, dry, and cool (15 to 26°C,
60-80°F).
Storage outdoors or for a
longer period
The unit should be packed with a
desiccant (silica gel) in a plastic bag or
similar, covered with plastic, and not
exposed to sunlight, rain, or snow.
This is also applicable for long-term
storage (more than 1 month) and for long
transport by sea.
Storage in a warm place
When the positioner is stored in a warm
place with a high relative humidity and
is subjected to daily temperature
variations, the air inside the unit will
expand and contract.
This means that air from outside the
unit may be drawn into the positioner.
Depending on the temperature
variations, relative humidity, and other
factors, condensation and corrosion can
occur inside the unit, which in turn can
give rise to functional disorders or a
failure.
If the positioner must be stored outdoors,
it is important that all the cover screws
are tightened and that all connections are
properly sealed.

3. Design
The D3 positioner contains:
• electronic board with microprocessor,
HART modem, display etc,
• pneumatic valve block,
• positional feedback with potentiometer,
• sealed compartment for electrical
connections.
Filter
The pushbuttons and display are
accessible underneath the aluminum
cover, which is sealed with an O-ring.

Double action function
The control signal and the feedback
potentiometer position are converted to
digital signals that are processed with a
PID algorithm in the microprocessor.
This provides control signals to the two
piezo-valves. The two piezo–valves are
closed in the schematic diagram above
and have no effect on the valves A and
D.
Air from the pressure regulator flows
through the open valve A to the valve B,
which opens. The supply pressure now
through valve B to the actuator via H.
The actuator then moves in the direction
of the arrow. At the same time, air flow
from valve A keeps valve C open and
allows venting of the actuator. When

both the piezo-valves open, valve A

valves E and F so that the actuator moves
in a direction opposite the arrow. When
only piezo-valve 1 is open, the actuator
is staionary.
Single action function
Valve B is used for the supply air and
valve F for venting. The positioner can
be converted from double acting to
single acting by installing a screw closing
H, described on page 36.
By converting to single acting function,
damper I is engaged. For double acting
function the screw should be installed at
G, bypassing damper I.

6. Installation
Air supply requirements
Max. air supply pressure, see the section
Technical Data on page 39.
The air supply must be free from
moisture, water, oil, and particles.
The air must come from a refrigeration
dried supply or be treated in such a way
that its dew point is at least 10°C, 18°F
below the lowest expected ambient
temperature.
To ensure a stable and problem-free air
supply, we recommend the installation
of a filter/pressure regulator <40µ as
close to the positioner as possible.
Before the air supply is connected to the
positioner, we recommend the hose is
opened freely for 2 to 3 minutes to allow
any contamination to be blown out.
Direct the air jet into a large paper bag
to trap any water, oil, or other foreign
materials. If this indicates that the air
system is contaminated, it should be
properly cleaned.
WARNING. Do not direct the
open air jet towards people or
objects because it may cause
personal injury or damage.
Poor air supplies are the main source
of problems in pneumatic and electropneumatic systems.
7
Mounting
NOTE! If the positioner is installed
in a hazardous environment, it
must be of a type approved for this
purpose.
The D3 positioner has an ISO F05
footprint, A. The holes are used to attach
it to the mounting bracket B, which is
suitable for most types of linear actuator.
It is important that the positioner ’s
spindle and the arms, that transfer the
actuator movements, are correctly
mounted. Any tension between these
parts can cause incorrect operation and
abnormal wear.
C
The spindle adapter C can be changed
to suit the actuator in question.
Remove the existing adapter using two
screwdrivers. Check that the spring ring
on the new spindle is undamaged before
installing.

8. Maintenance/service
When performing service, replacing a circuit board, or other repair, it may be
necessary to remove and refit various parts of the positioner. This is described on
the following pages.
Read the Safety Instructions on page 3 before starting work on the positioner.
Cleanliness is essential when working with the positioner. Contamination in
the air ducts will ultimately lead to operational disturbances. Do not disassemble
the 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 with
ESD protection before the work is started. Always turn off the air and electrical
supplies before starting any work.
Removing cover and inner
cover
A
• Unscrew the screws A and remove the
cover.
B
• Pull off the disc with the arrow B.
C
➜
• Unscrew the screws C, pull the inner
cover slightly in the direction of the
arrow, and remove the cover.
34
Circuit boards (pcb)
D
Disconnect or turn off the electric
power supply before starting any
work.
• Lift off the display pcb.
F
E
• Unscrew the spacers E, release the
cable connections F and G, and lift up
the processor pcb.
G
H
• Remove the terminal board by
unscrewing the spacers H.
35
Valve block
I
F
Turn off the air and electric power
supply before starting any work.
• Disconnect connector F from the processor pcb.
• Remove the four screws I.
• Lift out the valve block
NOTE! Do not disassemble the valve
block. Will not operate if opened.
Single/Double action
• The D3 can easily be converted from
double acting to single acting or vice
versa by moving screw J as shown.
For single action, screw should be placed
into the bottom of the housing.
Single action
J
Double action
For double action, screw should be
placed into the lower side of the valve
block. Factory default setting.
36
Potentiometer
The spring-loaded potentiometer K can
be removed from the gearwheel for
calibration or replacement.
If the potentiometer is replaced or the
setting is changed, it must be calibrated
in the menu Tuning - Expert - Ref cal pot.
K
Spindle adapter
The spindle adapter L can be changed to
suit the actuator in question.
L
• Remove the existing adapter using two
screwdrivers. Check that the spring
ring on the positioner’s spindle is
undamaged. Fit the new spindle.
Filter change
Turn off the compressed air supply
before starting any work.
Otherwise the filter can be
uncontrollably blown out of the
positioner by the air pressure,
which can be dangerous.
• Unscrew the filter with a coin or
similar.
.

9. Troubleshooting
Action
Fault symptom
• Check air supply pressure, air
cleanliness, and connection between
positioner and actuator.
Change in input signal to positioner does
not affect actuator position.
• Check input signal to positioner.
• Check mounting and connections of
positioner and actuator.
Change in input signal to positioner makes actuator move to its end position.
Inaccurate regulation.
Slow movements, unstable regulation.
• Check input signal.
• Check mounting and connections of
positioner and actuator.
• Implement auto-tuning. Check for
any 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 positioner on actuator.
• Dirty/humid supply air
• Implement auto-tuning.
• Adjust the pressure adjusting screws.
• Increase the deadband (Tuning
menu)
• Reduce Performance (Calibrate
menu)
