1. Introduction
The PMV D3 is a digital positioner designed primarily for controlling adjustable
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 contacts
- Two reed switches
- Two inductive sensors, DIN 19234
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 input signal fails or is switched 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 mode. 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 Manual mode, the valve can move quickly.
• Incorrect settings can cause self-oscillation, which can lead to damage.
Important
• Always turn of f 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.
• Always work in an ESD protected area when servicing the PCB´s. Make sure the
input signal is switched off.
• The air supply must be free from moisture, water, oil and particles.

2. Storage
General
The PMV positioner is a precision instrument. Therefore it is essential that it is
handled and stored in the right way . Always
follow the instructions below!
N.B. As soon as the positioner is
connected and started, internal air leakage
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, 59 to
79°F..
Storage outdoors or for a longer
period
If the positioner must be stored
outdoors, it is important that all the cover
screws are tightened and that all connections
are properly sealed. 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.

➾
Venting
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 is lead through the open valve A to
the valve B, which opens. The supply
pressure can now pass through valve B to
the actuator via H. The actuator then moves
in the direction of the arrow. At the same

time, air from valve A keeps valve C open
and allows venting of the actuator.
A closes but valve D opens and controls
valves E and F to that the actuator moves in
a direction opposite to the arrow. When only
piezo-valve 1 is open, the actuator is
stationary.

6. Installation
Tubing
Use tubes with an inner diameter of mi-
nimum 6 mm (1/4”).
Air supply requirements
Max. air supply pressure, see the section
Technical Data, Section 10.
The air supply must be free from
moisture, water, oil, and particles.
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.
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.
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 systems.

Mounting
N.B. 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.
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 positioner spindle is undamaged and fit
the new adapter.
Assembly examples
C
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.

8. Maintenance/service
When carrying out service, replacing a circuit board, etc., 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 infallible lead to operational disturbances. Do not disassemble the
unit more than that 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.
