Maintenance/service
Warning!
When upgrading electronically parts inside a PMV positioner approved for installation in Hazardous locations special procedures
apply, permission from PMV/Flowserve is required prior to the start of work. Please contact a Flowserve ofce for information
regarding proper procedures.
www.pmv.nu or infopmv@owserve.com
Warning!
Always turn off the air and electrical supplies before starting any work
General safety
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 ofce before continuing work.
Warning
The valve can open or close very quickly when in operation and, if handled incorrectly, may cause damages to ngers. There may
also be unintentional effects due to it fully opening or shutting off the ow in the process pipe. Please note the following:
• If the input signal fails or is switched off, the valve operates quickly to its default position.
• If the compressed air supply fails or is turned off, rapid 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 an internal or
external 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 operate 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 lter.
Remove or disconnect with care as air connection ”C-” is still under pressure even after the air supply is turned off.
• Always work in an ESD (Electrostatic Discharge) protected area when servicing the Printed circuit boards (PCB´s). Make sure the
input signal is switched off.
• The air supply must be free from moisture, water, oil and particles according to DIN/ISO 8573-1-2001 3.2.3

3. Storage
General
The D20-series positioner is a precision
instrument. Therefore, it is essential that it is
handled and stored in the correct way. Always
follow the instructions in this IOM!
Note: As soon as the positioner is connected
and started, internal air venting will provide
protection against corrosion and prevent the
ingress of moisture. For this reason, the air
supply pressure should always be kept on unless
repair/maintenance work of the positioner,
actuator or valve equipment is in progress.
Storage indoors
Store the positioner in its original packaging. The
storage environment must be clean, dry, and cool
(Temp -15°C to 25°C, 5°F to 77°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 open ports/connections are properly
sealed and/or plugged.
The red shipping plugs are not intended as a
permanent outdoor plug. 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.

7. Installation
WARNING! Do not direct the open air jet
towards people or objects because it may
cause personal injury or damage.
Removal of cover
General purpose / Intrinsically safe
Remove cover by rst loosening the screw 1and
then the two screws 2.
To install cover, rst tighten the screw 1, then the
two screws 2.
Tighten to 1.5 Nm ± 15%.
Air Preparation
Supply air should meet requirements specied
on page 5. A coalescing lter/regulator should
be installed in front of the supply air connection.
Connect the air supply to the lter, which is
connected to the D20 positioner.
Tubing
It is recommended to use tubes with a minimum
inner diameter of Ø 6 mm (¼”).
Air supply requirements
Poor quality air supply is the main cause of problems
in pneumatic systems.
The air supply must be free from moisture, water,
oil and particles and delivered @ 1.4-6 barg
(20-85 psi)
Standard: DIN/ISO 8573-1-2001 3.2.3
Filtered to 5 Micron, dew point -40°C/F
Oil 1mg/m³ (0,83 ppm by weight)
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.
Before the air supply is connected to the
positioner, we recommend the pipe/tube 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 before continuing.

Note: If the positioner is installed in a
hazardous environment, it must be of a type
approved for this purpose.
All versions of the D20 positioner have an ISO
F05 footprint. The holes are used to attach the
D20 to the mounting bracket B. Please contact
PMV or your local distributor representative
with actuator specics for the proper mounting
bracket and hardware.
The spindle shaft S09 can be used to suit various
actuators in question by the use of adaptors.
It is important that the positioner’s spindle shaft
and the lever arms, that transfer the actuator
movements, are correctly mounted. Any tension
between these parts can cause incorrect
operation and abnormal wear.

For Linear actuator
Mounting the positioner
1. Adjust the actuator to mid-stroke.
2. Pre-assemble the mounting bracket on the left
actuator leg hand-tight with two U-bolts, nuts
and lockwashers.
3. Attach the positioner to the pre-assembled
mounting bracket and fasten it with two hexagon
head screws and two lock washers. Check that
the follower pin is inserted in the slot of the take-
off arm and the follower arm is positioned at a
right angle to the outer edge of the positioner.
4. Tighten all screws and nuts.
NOTE: A slight unsymmetrical mounting increases the
linearity deviation but does not affect the performance
of the device. Depending on the actuator size and stroke
it may be necessary to ip the take-off arm by 180° and
attach it to the opposite side of the stem clamp bracket.

Mounting of the PMV D20 positioner on a
linear pneumatic actuator
(NAMUR / IEC 534 part 6)
The mounting of a rod actuator kit (according
to IEC 534 part 6) is described in an example by
using the following equipment:
Valve: Standard globe valve or equivalent
Actuator: Single-acting pneumatic actuator
Positioner: PMV D20 with mounting kit.
Pre-assembly: Valve with actuator (valve stroke
is matched with the actuator stroke).
For mounting, proceed as follows:
Mounting the Follower Arm (Figures 1 and 2)
1. Unscrew the lock nut for the follower arm
attachment.
2. Place the follower arm on the shaft at the
back of the positioner and fasten it with the lock
nut. The follower pin should point back from the
positioner.
CAUTION: Maximum torque
0,25 Nm (0,18 ft-lbs).
Mounting the stem clamp bracket and
take-off arm
1. Attach the stem clamp bracket to the stem
clamp and fasten it with two hexagon socket
screws and lock washers.
2. Attach the take off arm to the stem clamp
bracket and fasten it with a hexagon socket
capscrew and a washer. Ensure the take-off arm
slot is centered.

Follower pin adjustment
The positioner follower pin must be adjusted to
match the valve stroke in the following manner:
1. Adjust the follower pin (STROKE + 10 mm) as
indicated on the follower arm’s embossed scale.
2. Exhaust the actuator.
3. Loosen the follower pin and shift it along the
follower arm until the control marking on the
feedback gear is horizontal (points to the center
of the feedback potentiometer). Fasten the
follower pin in this position.
4. Adjust the actuator to full stroke and check
the follower pin adjustment the same way as
described in step 3. As the actuator strokes, the
rotation of the feedback gear should be between
the inner control markings. If the length of
rotation is outside the control markings, adjust
the follower pin farther out on the feedback lever
to reduce the angle of rotation.
NOTE: Stroke the actuator carefully and ensure
the follower arm does not interfere with valve
parts, actuator or positioner. Do not adjust the
follower pin too near to the slot end of the take-
off arm.
The minimum lateral distance should be
approximately 5 mm (0,2 inches) to prevent
bending of the feed-back mechanisim.

Electrical connections
Terminal block diagram for the D20-series.
The terminal block (right) for the positioner
is accessible when the aluminium cover is
removed. The D20-series digital positioner
has been designed to operate correctly in
electromagnetic (EM) elds found in typical
industrial environments. Care should be taken
to prevent the positioner from being used in
environments with excessively high EM eld
strengths (greater than 10 V/m). Portable EM
devices such as hand-held two-way radios
should not be used within 30 cm of the device.
Ensure proper wiring and shielding techniques
of the control lines, and route control lines away
from electro-magnetic sources that may cause
unwanted noise. An electromagnetic line lter
can be used to further eliminate noise. In the
event of a operability. It may be necessary to
recalibrate the D20-series positioner to restore
operation.
