INTRODUCTION
1.1
General
1.3
These instructions describe the digital Metso Automation
ND800PA valve position controller. The ND800PA can be used
with either cylinder or diaphragm type pneumatic actuators for
rotary or linear valves.
1.2
Principle of operation
The ND800PA is a fieldbus powered microcontroller-based valve
controller. The ND800PA configuration can be done either using
local push buttons, Simatic PDM (Process Device Manager) or some
other suitable Profibus PA configurator.
Using push buttons or PDM the configuration parameters can be
set according to the actuator and valve in question. Then auto-calibration can be started via push buttons or PDM. A three-digit display
with text labels describes the operation.
In control service the microcontroller (µC) reads data from the input
signal (Profibus PA), position sensor (α) and pressure sensor (p). A
change in input signal will be detected by control algorithm inside
the µC. The microcontroller will change the pilot current to one of
the prestage (PR) coils. A prestage valve lowers the pilot pressure
at the end of the spool valve (SV). The spool moves in the direction
of low pressure to open the flow in to the top of the actuator
cylinder and out from the other side of the piston. The increasing
pressure difference over the piston moves the piston and rotates
the feedback shaft. A position sensor ( a) measures the rotation for
the µC. Using a control algorithm the microcontroller adjusts the
pilot current until a new position of the actuator proportional to the
input signal is reached. In the steady state, the spool valve (SV) and
prestage (PR) valves are closed.
The valve controller is equipped with an identification plate
sticker (Fig. 2). Identification plate markings from top to bottom are:

Mounting on linear actuators with Metso
Automation or IEC 60534 mounting face
See Sections 10.5, 10.6.
Connect an airset directly to the actuator and position the
actuator at its mid-stroke position (see serial plate for
actuator stroke length).
Attach the feedback arm on to the controller input shaft.
Make sure the lettering on the feedback arm faces up,
toward the controller.
Attach the controller mounting bracket loosely on to the
slotted leg of the actuator. Make sure the marks on the
shaft and feedback arm operate in the quadrant shown.
Measure the distance from the centre of the feedback
lever shaft to the slot on the feedback lever and mark this
distance with a pencil or other marking instrument. Use
the dimensions given in Sections 10.5 and 10.6.
Mount the controller loosely onto the controller mounting
bracket.
Adjust the controller mounting bracket and the controller
so that the controller is at 90° to the centre line of the
actuator and the controller feedback lever is horizontal
and at 90° to the centre line of the actuator.
Tighten the controller mounting bracket screws.
Adjust the controller on the controller mounting bracket so
that the measured distance is maintained between the centre
of the feedback lever shaft and the actuator pin (pre-measured mark on the feedback lever). Note the controller must
still conform to the specifications in previous steps.
Tighten all the mounting bolts and then re-check that the
controller complies with previous steps. Check that the
actuator pin does not touch the controller case throughout the entire stroke of the actuator. If the actuator pin is
too long it may be trimmed to length. (The pin must be
trimmed on stroke of 1.125" or less.)
Attach the spring on to the feedback arm as shown.
Apply grease (Molykote or equivalent) to the contact surfaces
of the actuator pin and the feedback lever to reduce wear.
Increase and/or decrease air pressure to the actuator to
stroke the actuator full stroke to check that nothing is
binding and that the rotation of the feedback lever is 70°
for a 1"-5" stroke and 60° for a 3⁄4" stroke. See Sections
10.5 and 10.6.
2.5
Piping of supply air
CAUTION:
Do not exceed the permitted supply pressure
of the ND800PA!
Table 1 provides the recommended tube sizes in accordance with
actuator sizes. Tube sizes are the minimum values allowed. For
supply air choose a tube one size bigger. Operating times can be
tested by the PDM.
Connect the air supply to S (1/4 NPT).
Connect C1 and C2 (1/4 NPT) to the actuator.
For the pipe threads liquid sealants, such as Loctite 577, are
recommended.
NOTE:
Too much sealant may cause faulty operation of the controller.
Sealing tape is not recommended.
Ensure the cleaniness of the air piping.
The supply air must be clean, dry and oil-free instrument air, e.g.
according to standard ISA S7.3-81.
2.6
Electrical connections
The bus cable is led through a PG13,5 cable gland. Connect the
conductors to the terminal strip according to Fig. 6.
Reverse polarity protection permits connection of the bus cables in
any order.
Depending on the plant grounding policy, either Equipotential
Bonding or Capacitive grounding can be used. See "PROFIBUS - PA
User and Installation Guideline". In the case of Equipotential Bonding,
connect the cable shield to earth connection screw. In the case of
Capacitive grounding, connect the cable shield to terminal strip 1.

Keyboard functions
See keyboard operations (Fig. 11).
The keyboard setting state is initiated by pressing the + and - keys
for 5 seconds. The blinking text item m and one of the
previously selected operation modes, a, M or o, will
be shown on the display. If you want to change the operation mode,
press r first. a, M or o will start to blink showing that
the mode-changing function is enabled. Choose the desired mode,
a, M or owith the + or - key. After the mode has
been selected, press the r key.
The m function provides three alternative ND800PA operation modes:
a:
During a mode the ND800PA controls the valve position
according to the analog output block (AO) output signal. This mode
is used during normal process control service.
M:
During this mode the valve position can be manually controlled from
the keyboard + or - keys. The position of the manually driven valve
is not saved in the non-volatile memory of the ND800PA, i.e. the
valve does not return to the same position after power failure.
However, the valve can be driven back into position after power
failure by the + and - keys.
o:
When the o mode is activated the ND800PA closes the valve
and does not respond to incoming signal.
Accept the selected mode by pressing the r key which returns you
automatically to the setting state.

CONFIGURATION
4.1
Zero and range
The ND800PA position sensor operational range is factory adjusted
to suit Metso Automation actuators. If the ND800PA is to be fitted
into another manufacturer’s actuator, the sensor may need to be
readjusted as explained in Section 5.4.
Connect the air supply and fieldbus cable.
Select the c function from the keyboard according to 3.2.
Now you can select the a or M calibration mode
from the display by pressing the + or - key.
CAUTION:
Automatic calibration drives the valve against the
mechanical open and closed travel limits of the
valve-actuator assembly and a self-tuning procedure is performed. Make sure that these procedures can be safely executed.
Self-tuning procedure:
This is performed automatically during a or M
calibration.
As a result of self-tuning the g is set = 1 and b is set = 1.
d is originally factory set as explained in Fig. 7.
a calibration function:
For safety reasons the r key needs to be pressed for 5
seconds to activate the a calibration function. During
calibration the display shows the text CAL. After calibration
the ND800PA returns automatically to the setting function.
A self-tuning procedure is performed.
At any time you may interrupt the calibration sequences
by pressing the + and - keys simultaneously.
After the a calibration sequence is finished press the
+ and - keys simultaneously to get back to the operation
state. If this sequence has ended and an error message Err
appears on the display, see Chapter 6.
Now the ND800PA will work with basic settings including 2 ± 0.5 %
signal cutoff margins to secure full closing of the valve.
If you cannot drive the valve into a fully open position or if there is
no mechanical limit stop, proceed as follows:
M calibration function:
After selecting the M calibration function from the
display press the r key to activate the procedure.
With the + or - keys drive the valve manually to the
closed (0 %) position and then press the r key.
If you cannot drive the valve into the open position, you
may skip this sequence by pressing the + and - keys
simultaneously. Now the ND800PA assumes that the
maximum valve opening is the latest calibrated value. The
factory setting is 90°.
Drive the valve into the desired maximum opening position (100 %) with the + and - keys and press the r key.
A self-tuning procedure is performed.
If an error message Err appears on the display, see
Chapter 7.
Press the + and - keys simultaneously to return to the
operation state.
Now the valve controller will work with basic settings including
2 ± 0.5 % signal cutoff margins.
4.2
Position control
g is the gain parameter, d is the actuator pressure feedback
parameter and b is the valve velocity feedback parameter. The
default values after self-tuning are given in Fig. 7. Values are defined
for the control valve in question during self-tuning. However,
because of the large range of pressure drop and temperature for
the different processes, variations in supply air pressure and the great
variety of valve constructions, actuator load may differ considerably
from the default value. For this reason g, d and b may have to
be adjusted to ensure optimum control performance for special
cases. Use the following guidelines to adjust g, d and b.
Check that d value is according to Fig. 7.
Perform a or M calibration.
For enhanced control increase the g to value 1.2
If the valve is unstable, lower g until the valve is stable
at a constant input signal. If higher g is needed, increase
d to dampen instability with spring-return actuators.
If the valve is slow, increase g. If the valve is overshooting, decrease g. Adjust g for slight overshooting and then increase b to dampen it.
If the deviation between input signal and actual valve
position is high, increase g to decrease deviation.
However, avoid unstable operation.
g setting:
Select the g function from the keyboard according
to Section 3.2.
Now the display should indicate the current parameter
value. If you want to change it, press the r key.
Increase the parameter value by pressing the + key or
decrease its value by pressing the - key.
Press the r key when the desired value appears on the display.
Press the + and - keys simultaneously to return to the
operation state.
d setting:
The d parameters can be adjusted in the same manner.
(See Fig. 10).
The ND800PA stays in the selected operation mode during the
g and d settings.

Control valve related settings
Table 3.
The basic factory settings of the ND800PA assume a positioner fail
action to be closing the valve and a clockwise closing direction for
the position sensor. The setpoint cut-off CLOSE is set to 2 ± 0.5 %
to guarantee full closing of the valve against mechanical travel stops.

The next application-specific parameter rot defines the relationship
between position sensor rotation and valve action.
Once rot is displayed press the r key and the current
parameter value will be shown on the display. Now you
may select between two values by pressing the + or key. The value cC means clockwise rotation for closing the
valve and ccC means counterclockwise to close.
After the desired value is displayed, press the key r to
conclude the operation. See default values and tubing sizes
in Fig. 7 and functions in Fig. 10.
α0 setting (dead angle, A0)
The α0 setting is made for Metso Automation segment and ball
valves. This setting takes into account the “dead angle” α0 of the
ball valves. The entire signal range is then used for effective valve
opening 90° - α0 (Figure 12 and Table 3). Use 0 % as the “dead
angle” for the valves not mentioned in Table 3.
After selecting A0 on the display, press the r key and the
parameter value currently selected appears as a percentage (%) on the display.

MAINTENANCE
The maintenance requirements of the ND800PA valve controller
depend on the service conditions, for instance, the quality of instrument
air. In normal service conditions no regular maintenance is required.
The best reliability is achieved by following these instructions.
In the following text the numbers in parenthesis ( ) correspond to
the part numbers on the expoded view in Chapter 11, unless
otherwise stated.
The ND800PA valve controller includes the following interchangeable modules: prestage (3), spool valve (4), circuit board pack (5),
position sensor (6), and differential pressure sensor (7).
The modules are located underneath a protective cover (46) which
is attached with M3-screws (48, 4 pcs.). If a module fails it must be
changed. The module retrofit must be made in a clean, dry
environment. After replacement apply thread-locking compound
(for instance, Loctite 243) and tighten the screws firmly.
5.1
Prestage
NOTE:
The prestage must be handled very carefully. In particular the moving
parts on both ends of the prestage should not be touched when
the prestage is functioning and the protective cover is not in place.
Disassembly
Unplug the prestage (3) wire connectors from the circuit
board (5). Unscrew the M4 screws (92, 2 pcs.) and
remove the prestage module.
Reassembly
Place the O-rings (91) in the respective grooves and press
the prestage into place. Make sure that the nozzles are
properly guided on top of the O-rings. The screws guide
the prestage body into the correct position.
Push the prestage 2-pole wire connectors into the sockets on
the circuit board. Make sure that the wires do not cross each
other. The wire connectors can only be fitted in the correct way.
Tighten the screws (92) evenly with a torque of approx.
0.8 Nm (0.6 ft.lb).
Set the protective cover (46) carefully in place and tighten
the screws (48).
14
5.2
Spool valve
5.3
Before removing the spool valve (4) the prestage (3) must be taken
off. (See Section 5.1)
Disassembly
Unscrew the M4 screws (99, 4 pcs.) and remove the spool
valve assembly.
The spool valve can be cleaned by following especially clean and
careful procedures. The seal (106), filter (105), restriction (104)
and spring (100) are located at the ends of the spool valve (102,
103). The spool (97) can also be removed for cleaning.
NOTE:
Each spool valve body has an individual matching spool which
cannot be replaced by any other spool. Never change the orientation of the spool or the location of the individual spool springs.
Reassembly
Place a new gasket (98) in the location determined by the fitting
screw holes. Fit the spool valve into its corresponding position
on top of the seal and tighten the M4 screws (99) evenly.
The O-rings must be mounted first in their grooves located in
the spool valve unit. During mounting the O-rings must be
compressed because the sealing is done radially. Make sure that
the O-rings are evenly compressed and that they are fully inside
the grooves. The O-rings must be in perfect condition; no
defects are allowed. If a tool is used it must be blunt.
Mount the prestage unit directly onto the spool valve unit.
The ends of the nozzles will guide the prestage unit to the
right location. The prestage unit must fit by pushing gently
with no excessive force. Ensure that the spool valve unit
and the prestage unit have an even surface connection
before tightening the screws.

NOTE:
Ground yourself on the body of the device before touching
the circuit board pack.
Take hold of the sides of circuit board and lift it directly
upwards and outwards. Handle the board carefully, touching only the sides.
Reassembly
Remount the circuit board pack carefully. Do not let the
feedback shaft touch the circuit board.
Locate the pins of the pressure sensor on the matching
connections on the board.
Tighten the M3 screws (111) evenly.
Push the rubber grommet into the slot located on the
intermediate wall of the body and connect the wires to
the terminal block as shown in Fig. 14. Plug the prestage
wire connectors into the board making sure that the wires
do not cross each other. Plug the position sensor (6) wire
connector into the board.
Mount the protective cover (46).
Mount the position indicator (65) on the shaft and tighten
the M8 screw (66) temporarily. The final locking of the
position indicator occurs when the actuator is installed.
NOTE:
Changing a new circuit board pack requires updating the
module parameters using PDM communication. See the instructions provided with the new circuit board.

ERROR MESSAGES
When the ND800PA detects serious device failure (analogue
inputs, analogue outputs or electronics) it enters fail-safe mode
which drives the control valve into the position defined in the
parameter positioner fail action (PFA). Fail-safe mode is indicated by
the LCD as message Exx, where xx is a number between 1-99, or
by the PDM. The error message is displayed until the cause of error
is eliminated and the ND800PA unit is cold-started, i.e. the fieldbus
is momentarily disconnected. Cold-start can also be done using
PDM.

Safety precautions
CAUTION:
Do not exceed the limit switch performance limitations!
Exceeding the limitations marked on the limit switch may
cause damage to the limit switch, actuator and valve. Damage
or personal injury may result.
CAUTION:
Observe caution with the live parts of the limit switch!
The limit switches are fed with a voltage that, depending on
the system, may be lethal.
Do not touch any uncovered parts of the wires. Always
disconnect the wires before dismantling the limit switch.

10.2
Installing ND800PA/K06B on a valve
controller
The limit switch can be installed on an existing valve controller.
NOTE:
Do not install a ND800/K06B limit switch on a ND800/X valve controller!
If the valve controller is already mounted on an actuator/valve assembly, operate the actuator into the closed
or open position.
Remove the cover (2) and the pointer (65).
Turn the shaft (304) onto the shaft (40). Fasten the screw
(305) using a locking agent such as Loctite. Unfasten the
screws (331) in the cam discs (330).
Mount the housing (300) on the valve controller.
Turn the cam discs (330) to avoid contact with the
microswitches, if needed.
Mount the pointer (65) on the shaft (304).
Adjust the limit switch according to Section 10.4.
10.3
Electrical connections
Before connecting the power, make sure that the electrical specifications and the wiring meet the installation conditions. See the
diagram in Section 11.12. See also the information on the identification plate.
10.4
Adjustment
The pointer (65) need not be removed for adjustment.
When the limit switch is ordered together with the valve and the
actuator, the valve controller switches are factory-adjusted.
The limits can be adjusted by changing the position of the cam discs
(330) on the shaft. The lower switch is activated at the closed limit
and the upper switch at the open limit.
With the actuator in the open or closed position, find the switching
point by turning the cam disc so that the switch changes about 5°-6°
before the limit.
After re-installation of the actuator, first adjust its mechanical limits
according to the valve, then the valve controller, and finally the limit
switch.
When adjustment is completed, turn the pointer (65) so that
the yellow line is parallel with the valve closure member.

Removal of the limit switch ND800PA/K06B
for accessing the valve controller
Before the protective cover (46) can be removed the limit switch
must be detached.
Remove the cover (2) and the pointer (65).
Loosen the screws (302) and remove the housing (300).
Detach the shaft (304) with cam discs (330).
Proceed with the valve controller as applicable.
Re-install the limit switch according to Section 10.2 and check the
adjustment according to Section 10.4.
10.6
Circuit diagrams
The internal circuitry of the limit switch is shown in the connection
diagram in Section 11.12 and on the sticker inside the cover.
10.7
Maintenance
Regular maintenance of the limit switch is not necessary.
10.8
Ordering spare parts
NOTE:
Always use original spare parts to make sure that the limit
switch functions as intended.
When ordering spare parts, always include the following information:
limit switch type designation (from the name plate or
switch documents)
number of the spare parts list or number of this manual,
part number, part name and quantity required

Notes:
1. For installation in a Division 1 hazardous (classified) location or a Zone 0 / 1 hazardous (classified)
location, the wiring must be in accordance with the Canadian Electrical Code CSA C22.1 Part 1.
2. The Entity Concept allows interconnection of intrinsically safe and associated apparatus not specifically
examined in combination as a system when the approved values of Voc ( or Uo) and Isc (or Io) for the
associated apparatus are less than or equal to Vmax (or Ui) and Imax (or Ii) for the intrinsically safe
apparatus and the approved values of Ca (or Co) and La (or Lo) for the associated apparatus are greater
than Ci + Ccable, Li + Lcable, respectively for the intrinsically safe apparatus.
3. Note associated apparatus with only Zone 1 approved connections limits the mounting of the valve
controller to Zone 1. Also associated apparatus with Group IIB connections or if in minimum one device at
the fieldbus cable is specified only with IIB limits the complete fieldbus segment to IIB.
4. The metallic enclosure of the ND800 valve controller must be grounded and bonded in accordance with
the Canadian Electrical Code CSA C22.1
5. The cover of the ND800 enclosure may be removed in hazardous location for reading the display and
operating the push buttons. The internal cover of the electronic circuits must not be removed in hazardous
areas.
6. The valve controllers ND83_/ZU and ND84_/ZU are non-incendive for Class I, Division 2, Groups A,B,C,
and D; Class I, Zone 2, Groups IIC, IIB, IIA T5 / T6 hazardous (classified) locations and need to be
connected to an associated apparatus with a max. output voltage of 22,5V.
