1. Introduction

The D30 is a digital positioner designed

primarily for controlling modulating valves. The

positioner can be used with single or double

acting actuators with either rotary or linear

movement.

The D30 can be equipped with modules for

limit switches and pressure gauges. Pressure

sensors can be installed to offer advanced

diagnostics.

The modules can be factory assembled before

delivery or ﬁtted later.

The modules for limit switches can contain one

of the following:

• Two mechanical contacts

• Two proximity switches

• Two inductive sensors

Warning!

Special Conditions for Safe Use

The enclosure of PMV D30 Intrinsically safe version is made of aluminium and any impact

or friction caused by external objects shall be avoided in the application.

The surface area of the plastic parts on the cover exceeds the limits speciﬁed in EN

60079-0 for II 1G (EPL Ga) for gas group IIC and intensive rubbing or brush charging

should be avoided when used in an IIC explosive atmosphere.

The cable connection of the Remote Unit with the D30 – unit shall be type A or B in

accordance with EN 60079-25. The cable must be adequately mechanically protected in

all instances and have a temperature rating for the ambient temperature range at the site.

Control Drawing D4-086C contains the parameters for intrinsically safety.

The intrinsic safe circuits D30 is insulated from earth and complies with the dielectric

strength test of 500 VAC.

In a hazardous environment where there is a risk of explosion, electrical connections

must comply with the relevant regulations.

Do not disconnect equipment unless area is known to be non-hazardous. or; read,

understand and adhere to the manufacturer’s live maintenance procedures. To prevent

ignition of ﬂammable or combustible atmospheres, disconnect power before servicing,

Substitutions of components may impair suitability for hazardous (classiﬁed) locations.

When installing PMV D30 Intrinsically safe unit always consult drawing D4-086C

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 ofﬁce for information regarding proper

procedures www.pmv.nu or infopmv@ﬂowserve.com

-Always turn off the air and electrical supplies before starting any work.

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 can open or close very quickly when in operation and, if handled incorrectly, it may

cause damages. There may also be unintentional effects due to it fully opening or shutting

off the ﬂow 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 operates 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 as air connection

”C-” is still under pressure even after the air supply is turned off.

• Always work in an ESD (Emergency 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.

2. Storage

General

The D30 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.

Keep the cover mounted on the positioner and

replace any damaged window.

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 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.

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 - without air

supply pressure applied - 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.

3. Installation

Removal of cover

General purpose / Intrinsically safe

Remove cover by ﬁrst loosening the screw 1

and then the two screws 2.

To install cover, ﬁrst tighten the screw 1, then

the two screws 2.

Tighten to 1.5 Nm ± 15%.

Supply air should meet requirements speciﬁed

on page 5. A coalescing ﬁlter/regulator

should be installed in front of the supply air

connection. Now connect the air supply to the

ﬁlter, which is connected to the D30 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 @ 1.4-8

barg (20-115 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.

To ensure a stable and problem-free air supply,

we recommend the installation of a

coalescing ﬁlter/regulator <5µ 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 before continuing.

WARNING! Do not direct the open air jet

towards people or objects because it may

cause personal injury or damage.

Mounting

Note: If the positioner is installed in a

hazardous environment, it must be of a type

approved for this purpose.

All versions of the D30 positioner have an ISO

F05 footprint. The holes are used to attach the

D30 to the mounting bracket B. Please contact

PMV or your local distributor representative

with actuator speciﬁcs for the proper mounting

bracket and hardware.

The spindle shaft S09 can be changed 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.
