2 ND9200H INTELLIGENT VALVE

CONTROLLER WITH HART

COMMUNICATION

2.1 General

This manual incorporates Installation, Maintenance and

Operation Instructions for the Metso Automation

ND9200H intelligent valve controller. The ND9200H may

be used with either cylinder or diaphragm type pneu-

matic actuators for rotary or linear valves.

2.2 Technical description

The ND9200H is a 4–20 mA loop-powered microcontrol-

ler-based intelligent valve controller. The device operates

even at 3.6 mA input signal and communicates via HART.

The device contains a Local User Interface enabling

local configuration. A PC with FieldCare software can be

connected to the ND9200H itself or to the control loop.

The powerful 32-bit microcontroller controls the valve

position. The measurements include:

❑Input signal

❑Valve position with contactless sensor

❑Actuator pressures, 2 independent measurements

❑Supply pressure

❑Spool valve position

❑Device temperature

Advanced self-diagnostics guarantees that all measure-

ments operate correctly. Failure of one measurement

does not cause the valve to fail if the input signal and

position measurements are operating correctly. After

connections of electric signal and pneumatic supply the

micro controller (µC) reads the input signal, position sen-

sor (α), pressure sensors (Ps, P1, P2) and spool position

sensor (SPS). A difference between input signal and

position sensor (α) measurement is detected by the con-

trol algorithm inside the µC. The µC calculates a new

value for prestage (PR) coil current based on the infor-

mation from the input signal and from the sensors.

Changed current to the PR changes the pilot pressure to

the spool valve. Reduced pilot pressure moves the spool

and the actuator pressures change accordingly. The

spool opens the flow to the driving side of the double

diaphragm actuator and opens the flow out from the

other side of the actuator. The increasing pressure will

move the diaphragm piston. The actuator and feedback

shaft rotate clockwise. The position sensor (α) measures

the rotation for the µC. The µC using control algorithm

modulates the PR-current from the steady state value

until a new position of the actuator according to the input

signal is reached.

2.3 Markings

The valve controller is equipped with an identification

plate sticker (Fig. 2).

Identification plate markings from top to bottom include:

❑Type designation of the valve controller

❑Revision number

❑Enclosure class

❑Operational temperature

❑Input signal (voltage range)

❑Input resistance

❑Maximum supply voltage

❑Supply pressure range

❑Contact details of the manufacturer

❑CE mark

❑Manufacturing serial number TTYYWWNNNN*)

*) Manufacturing serial number explained:

TT= device and factory sign

YY= year of manufacturing

WW = week of manufacturing

NNNN = consecutive number

Example: PH03011234 = controller, year 2003, week 1,

consecutive number 1234.

NOTE:

The selection and use of the valve controller in a specific

application requires close consideration of detailed

aspects. Due to the nature of the product, this manual

cannot cover all the likely situations that may occur when

installing, using or servicing the valve controller.

2.6 Safety precautions

3 MOUNTING

3.1 General

If the ND9200H is supplied with valve and actuator, the

tubes are mounted and the ND9200H adjusted in

accordance with the customer’s specifications. If the

controller is ordered separately, the mounting parts for

the assembly must be ordered at the same time.

Sample order: (B1CU13)-Z-ND9206HN

The controller is equipped with the Metso Automation

flush mounting face, the old Neles mounting face and for

connection according to VDI/VDE 3845.

Shaft coupling alternatives for the controller for Metso

Automation actuators are shown in Fig. 5.

For mounting parts for Metso Automation actuators, see

10.2 - 10.8.

3.2 Mounting on EC and EJ actuators

For EC actuators see figure in Section10.2.

For EJ actuators see figure in Section10.3.

❑Mount the U-shaped coupling (47) to the shaft.

Apply thread-locking compound to the screws

(48) and tighten firmly.

CAUTION:

Do not exceed the permitted values!

Exceeding the permitted values marked on the valve

controller may cause damage to the controller and to

equipment attached to the controller and could lead

to uncontrolled pressure release in the worst case.

Damage to the equipment and personal injury may

result.

CAUTION:

Do not remove or dismantle a pressurized controller!

Removing or dismantling a pressurized prestage or

spool valve of an ND9200H leads to uncontrolled

pressure release. Always shut off the supply air and

release the pressure from the pipelines and equip-

ment before removing or dismantling the controller.

Otherwise personal injury and damage to equipment

may result.

WARNING:

During automatic or manual calibration and tuning

the valve operates between open and closed posi-

tions. Make sure that the operation does not

endanger people or processes!

Ex d WARNING:

Do not open the device when energized!

Explosion protection is lost.

Electromagnetic immunity is reduced, valve may

stroke.

Ex d WARNING:

Use a cable gland with suitable Ex d certification.

For ambient temperature over 70 °C / 158 °F use a

heat resistant cable and cable gland suitable for at

least 90 °C / 194 °F.

NOTE:

Avoid earthing a welding machine in close proximity to

an ND9200H valve controller.

Damage to the equipment may result.

Ex d NOTE:

Follow the installation guidelines in EC-EN 60079-10

when mounting the equipment.

NOTE:

The enclosure of ND9200H intelligent valve controller

meets the IP66 protection class according to EN 60529

in any position when the cable entry is plugged accord-

ing to IP66.

Based on good mounting practice, the recommended

mounting position is electrical connections placed

downwards. This recommendation is shown in our

mounting position coding for control valves.

If these requirements are not fulfilled, and the cable

gland is leaking and the leakage is damaging valve

controller or other electrical instrumentation, our war-

ranty is not valid.

Fig. 3 Mounting on EC and EJ actuators

O-rings

Fig. 4 Mounting on Metso Automation actuator with

VDI/VDE mounting face

The pointer on the coupling must

stay in this sector

❑Adjust the distance of the positioner to the pin on

the actuator stem so that the pin stays in the lever

slot at full stroke. Ensure also that the maximum

angle of the lever does not exceed 45° in either

direction. Maximum allowed travel of the lever is

shown in Section 10.8. Best control performance

is achieved when the feedback lever utilises the

maximum allowed angle (±45° from horizontal

position). The whole range should be at least 45°.

❑Make sure that the positioner is in right angle and

tighten all the mounting bolts.

❑Ensure that the positioner complies with previous

steps. Check that the actuator pin does not touch the

positioner case throughout the entire stroke of the actu-

ator. If the actuator pin is too long it may be cut to size.

❑Apply grease (Molykote or equivalent) to the con-

tact surfaces of the actuator pin and the feed-

back arm to reduce wear.

3.6 Piping

Table 2 provides the recommended tube sizes in

accordance with actuator sizes. Tube sizes are the mini-

mum values allowed. For supply air choose a tube one

size bigger. Operating times may be tested by the Field-

Care software.

Connect the air supply to S (1/4 NPT ).

Connect C1 and C2 (1/4 NPT) to the actuator, see Fig. 6.

ND9200H is connected direct to the EC or EJ actuator.

Connections C1 and C2 (1/4 NPT) must be plugged, see

10.2 and 10.3.

Liquid sealants, such as Loctite 577 are recommended

for the pipe threads.

The air supply must be clean, dry and oil-free instrument

air, see Section 2.4.
