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.
If you are uncertain about the use of the controller or its

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.

❑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.

3.7 Electrical connections
The ND9200H is powered by a standard 4–20 mA cur-
rent loop that also functions as a carrier to the HART
communication.
The input signal cable is led through a M20 x 1.5 (E1)/
1/2 NPT (E2) cable gland. Connect the conductors to the
terminal strip as shown in Fig. 7. It is recommended that
the earthing of the input cable shield be carried out from
the DCS end only. The terminal 'SHD' (see Fig. 7) allows
user to connect the input cable shield also to the
ND9200H.
The position transmitter is connected to 2-pole terminal
PT as shown in Fig. 7. The position transmitter needs an
external power supply. The ND9200H and the position
transmitter circuits are galvanically isolated and with-
stand a 600 VAC voltage.
NOTE:
The ND9200H equals a load of 475 Ωin the current
loop.

4 LOCAL USER INTERFACE (LUI)
The local user interface may be used to monitor the
device behaviour as well as configuring and commis-
sioning the controller during installation and normal
operation. The local user interface consists of 2 row LCD
and 4 button keypad interface. There are also custom
graphical characters for special conditions.
4.1 Measurement monitoring
When the device is powered, it enters the measurement
monitoring view. The following measurements may be
viewed from the display. The Table 3 identifies the default
unit and also optional unit of the measurement.
If the unit selection is altered from the FieldCare software
to US units, the pressure default unit will automatically be
changed to psi and temperature unit to Fahrenheit.
The active unit may be changed by pressing the ?key
constantly. The display shows the current unit selection
on the top row of the display. You may change the selec-
tion by pressing +or -while keeping the ?key
pressed down. When the buttons are released the cur-
rent selection will be activated.
If the device has been idle for 1 hour, and there is no
user activity on the local user interface, the measure-
ments will start scrolling on the display. This enables the
user to view all the measurements through the window of
the main cover.
4.2 Guided start-up
Guided startup offers a fast view of the most critical
parameters of the ND9200H controller, actuator and
valve configuration. After verifying the parameters the
valve travel calibration is recommended. The guided
start-up is entered by pressing the =and ?keys
simultaneously.
The configuration parameters are listed in following
order, see explanation from 4.5:
Valve type VTYP
Actuator type ATYP
Positioner fail action PFA
Valve rotation direction ROT
Valve dead angle A0
If you modify any of the parameters you will also need to
calibrate and tune the device. See 4.6 for detailed
description.

4.3 Configuration menu
The local user interface is organised in a menu struc-
ture. To enter the menus press +and -simultaneously
in the measurement monitoring view panel. To move to
the next or previous selection by pressing +or -
accordingly.
4.4 Mode menu
If the user wants to change the valve operating mode,
press the ?key at the MODE selection. The mode will
start to flash and by pressing +or -you may alter the
operation mode selection. User accepts the current
selection by pressing the ? key.
There are two options for the operating mode.
4.4.1 AUTO
During the auto mode, the controller controls the valve
position according to the incoming setpoint signal from
the 4–20 mA signal source. This mode is used during the
normal process control service.
4.4.2 MAN
During this mode the valve position may be controlled
manually by using the keyboard and pressing the +or
-buttons. The position of the manually driven valve is not
saved in the memory of the controller, i.e. the valve will not
return to the same position after signal failure. However,
the valve may be driven back into position after signal fail-
ure by using +and -keys.The manual control starts
from the current position of the valve after the MAN-mode
is activated. In order to change the manual setpoint return
to the measurement monitoring view and go to setpoint
measurement. Press the ?key shortly to activate the set-
point editing, text SETP starts to blink and now you are
able to edit the setpoint by pressing +or -button. The
setpoint changes in 0.1 % increments/decrements in spite
of the selected unit and the valve starts to move immedi-
ately. A continuous push changes the setpoint faster. In
order to view other measurements, press the ?or =
keys and select a measurement. Repeat the previous
steps if you would like to alter the setpoint value again.

❑Press the ?key to make your selection and
return to the setting state.
4.5.9 Low cut-off, low limit, high cut-off,
high limit
ND9000 supports signal cut-off and limiting in both ends
of the operating range. The configuration parameters
are; low cut-off, low limit, high cut-off and high limit.
❑If the input signal is smaller than low cut-off, the
valve will be fully closed.
❑If the input signal is smaller than low limit, the
valve stays in the low limit.
❑If the input signal is greater than high cut-off, the
valve will be fully opened.
❑If the input signal is greater than high limit, the
valve stays in the high limit.
The cut-off overrides the limit as follows:
❑If the low cut-off > low limit, the low limit is not
active.
❑If the low cut-off < low limit, both low cut-off and
limit are active.
❑If the low cut-off is set to zero, the low cut-off is
not active.
❑If the high cut-off < high limit, the high limit is not
active.
❑If the high cut-off > high limit, both high cut-off
and limit are active.
❑If the high cut-off is set to 100 %, the high cut-off
is not active.
Only the low cut-off is adjustable using the LUI. Low limit, high
cut-off and high limit are configurable via FieldCare software.
NOTE:
Perform valve calibration and tuning always when con-
troller fail action parameter has been changed.

4.6 Valve travel calibration
Select CAL from the menu by using +or -keys and
press the ?key. Define the calibration type AUTO, MAN
or TUNE. You may also select TUNE after AUTO and MAN
calibration separately as seen in Fig.16.
4.6.1 AUTO calibration function
During the calibration process the display will show the
following text: CALrun. After calibration the ND9200H
scrolls CALIBRATION SUCCESSFUL text. You may inter-
rupt the calibration sequences at any time by pressing
the =key.
After the calibration sequence is finished, press the =
key twice to get back to the measurement view.
Please refer to Chapter 6 if this sequence has failed and
an error message is displayed.
If you cannot drive the valve into a fully open position or if
there is no mechanical limit stop, a manual calibration is
required.
4.6.2 MAN calibration function
After selecting the MAN calibration function from the
menu press the ?key to activate the procedure. With
the +or -keys drive the valve manually to the closed
(0 %) position and then press the ?key. If you cancel
the operation, the old values of the previous calibration
will be restored. Drive the valve into the desired maxi-
mum opening position (100 %) with the +and -keys
and press the ?key.
If this sequence has failed and an error message is
shown, see Chapter 6.
4.6.3 TUNE function
During the tuning the ND9200H controller searches for
optimum internal control parameters for the valve posi-
tion control. At any time you may interrupt the tuning
sequence by pressing the =key. The tuning will not
alter the PERF parameter.
If calibration and tuning are performed in sequence, the
cancelling of tuning does not restore the old calibration
values.
4.7 Special displays
4.7.1 User interface locked
In order to prevent unauthorised access, the Local User
Interface may be locked. In this mode measurements
may be viewed but configurations and calibrations are
prohibited. You may lock and unlock the device only via
HART. When the Local User Interface is locked the lock
symbol will be activated on the display.
4.7.2 Online-alarm active
If an online alarm has been detected the &symbol is
activated. This symbol will disappear after the recovery
from online alarm. You may view the reason for the alarm
by viewing the latest event while pushing the =and -
keys simultaneously or by using FieldCare software
where all events may be viewed.
4.7.3 Viewing of latest event
You may view the latest event by pressing the =and -
keys simultaneously in the measurement monitoring
view. The message is scrolled on the top row of the dis-
play twice. You may stop the scrolling by pressing the ?
key. By pressing the =key, the message will disappear.
For the list of events see Chapter 6.
NOTE:
Valve travel calibration is possible only when the valve
controller is in AUTO mode.

4.7.4 Fail-safe active
When the ND9200H detects serious device failure (set-
point, valve position and control signals) it enters fail-
safe mode, which drives the control valve into the posi-
tion defined in the parameter controller fail action (PFA).
Fail-safe mode is indicated by the display as seen in Fig
19. The error message is displayed until the cause of
error is eliminated and the ND9200H unit is restarted, i.e.
the power loop is momentarily disconnected.
4.8 HART write protection
The ND9200H is delivered from the factory with the
default set as HART write protection OFF. Reading and
changing parameters is allowed. HART protection may
be enabled with a switch (DIP1) located on the commu-
nication circuit board under the Local User Interface
module, Fig. 20. Changes that may influence the valve
position cannot be made using the FieldCare software or
HART hand held when switch no. 1 (on the left-hand side
of the switch block) is ON.
5 MAINTENANCE
The maintenance requirements of the ND9200H valve
controller depend on the service conditions, for
instance, the quality of instrument air. Under normal
service conditions there is no requirement for regular
maintenance.
When maintaining the ND9200H ensure that the supply
air is shut off and pressure is released. In the following
text the numbers in brackets ( ) correspond to the part
numbers in the exploded view as shown in Chapter 10,
unless otherwise stated.
The ND9200H valve controller includes the following
interchangeable modules: prestage unit (120), spool
valve (193), communication circuit board with optional
position transmitter (215) and controller circuit board
with position and pressure sensors (210 ).
The spool valve is located on the bottom side of the
device while the other modules are located below the
covers (100) and (39). In the event of failure the whole
module must be changed. The module retrofit must be
assembled in a clean, dry environment. In reassembly
apply a thread-locking compound (for instance, Loctite
243) and tighten the screws firmly.
5.1 Prestage
5.1.1 Removal
❑Loosen the M8 stop screw (110) in the position
indicator (109) and turn the position indicator
from the shaft (11). Remove the inner cover (39)
attached with M3 screws (42, 3 pcs).
❑Unplug the prestage wire connector from the
spool sensor board (180). Unscrew the M4
screws (139, 2 pcs.) and lift up the prestage
module. Remove the O-ring (140).
5.1.2 Installation
❑Place a new O-ring (140) into the groove in the
housing and press the prestage into place. Make
sure the nozzle is guided into the O-ring properly.
The screws guide the prestage body into the cor-
rect position. Tighten the screws (139) evenly.
❑Push the prestage 2-pole wire connector into the
socket on the spool sensor board. The wire con-
nector can only be fitted in the correct position.
Replace the inner cover (39) and tighten the M3
screws.

5.2 Spool valve
5.2.1 Removal
For spool valve removal it is usually necessary to
unmount the valve controller from the actuator.
❑Working from the bottom side of the valve con-
troller, unscrew the M4 screws (47, 3 pcs.).
Remove the spool valve cover (61) and the spool
valve (193) with gasket (174). Hold the ends of
the body with your fingers to avoid dropping the
spool from the body.
❑Spool valve removal is only possible in the
spring-forced failsafe position of the spool. In the
case of a stuck spool it might be necessary to
remove the secondary diaphragm cover (167),
the spool spring (166) with its disc (164) and the
secondary diaphragm (162) with its plate. After
the removal of these parts it is possible to use a
punch to force the spool to the failsafe position.
❑The spool valve may be cleaned if special atten-
tion is paid to a clean environment and proper
procedure.
❑Clean the spool and the bore of the body with
care. Do not leave any fibres from cleaning mate-
rials in the bore or on the spool. Do not scratch
the mating surfaces of the spool and body.
5.2.2 Installation
❑Ensure that the gaskets (174) and (63) are prop-
erly located in their grooves on the bottom of the
housing. Mount the spool valve and the spool
valve cover (61) to the housing, and tighten M4
screws evenly.
5.3 Flame arrestor assembly
The flame arrestor and the restrictor are fit into the same
plug which is located under the diaphragm cover (171).
This assembly can not be disassembled and should be
replaced if clogged.
❑To remove the flame arrestor assembly, unscrew
the screws (173, 4 pcs) and remove the dia-
phragm cover (171) with its O-ring. Turn a M3
screw into the threaded hole of the flame arrestor
assembly to extract it from the housing. Installa-
tion is the reversal of removal. Place the O-rings
carefully.
5.4 Diaphragms
The diaphragms (169, 162) may be replaced by remov-
ing the respective covers (171, 167). The unit should be
unmounted from the actuator and the side to be worked
on turned upwards in order to avoid loss of small parts.
When replacing the secondary diaphragm (162), the
spool spring (166) with its guide (164) has to be
removed first. When reassembling, pay special attention
to the installation of the diaphragms and O-rings.
5.5 Communication circuit board
5.5.1 Removal
❑Loosen the M8 stop screw (110) in the position
indicator (109) and turn the position indicator
from the shaft (11). Remove the inner cover (39)
attached with M3 screws (42, 3 pcs).
❑Remove the M3 screws (217, 4 pcs.). Hold the
sides of the circuit board and lift it directly
upwards and outwards. Handle the board care-
fully, touching only the sides.
5.5.2 Installation
❑Mount the new communication circuit board
carefully.
❑Locate the pins with the matching connector on
the board. Tighten the M3 screws (217) evenly.
❑Install the inner cover (39).
❑Mount the position indicator (109) on the shaft
and tighten the M8 stop screw (110) temporarily.
The final orientation and locking of the position
indicator should be done after installation of the
valve controller to the actuator.
NOTE:
Each spool valve body has an individual correspond-
ing spool which cannot be replaced by any other
spool. Never alter the orientation of the spool. The ori-
entation of the spool is marked on the device, see
Fig. 21.
