1 VG9000F VALVGUARD
INTELLIGENT SAFETY SOLENOID
WITH FOUNDATION FIELDBUS
COMMUNICATION
1.1 General
This manual incorporates Installation, Maintenance and
Operation Instructions for the Metso’s Neles ValvGuard
VG9000F. The VG9000F may be used with either cylinder or
diaphragm type pneumatic actuators for rotary or linear
valves.
1.2 Technical description
Neles ValvGuard VG9000F is a microcontroller-based safety
solenoid and partial stroke test device with FOUNDATION
fieldbus communication. Addition to FOUNDATION fieldbus
there is also a separate binary 24 V DC signal needed. It is
isolated from the fieldbus and powers the safety part.
Main components of ValvGuard are spool valve (SV), pre-
stage unit (PR) and micro controller (µC). Spool valve and
prestage unit are the only components, which takes part of
the safety action. Spool valve controls the main airflow
between supply-, actuator- and exhaust connections. The
spool is operated by spring force to fail safe position and by
pneumatic force generated by the prestage valve to the
normal position. The prestage valve is coil operated flapper
valve (normally open). Coil of the prestage is energized with
the safety signal (24 V DC) and controlled by the micro con-
troller. Micro controller cannot prevent the safety action.
Pressure sensors (Px) and position sensor (α) are used to
getting the measurements for controlling the PST and other
tests. Measurements from the sensors are used for the
device diagnostics.
The device contains a Local User Interface enabling local
configuration. A PC with FieldCare software can be used for
advanced configuration and diagnostics.
The powerful 32-bit microcontroller controls the valve posi-
tion during partial stroke and other special testing. The
measurements include:
Safety signal
Valve position with contactless sensor
Actuator pressures, 2 independent measurements
Supply pressure
Device temperature
Housing pressure
Advanced self-diagnostics guarantees that all measure-
ments operate correctly. Failure of any measurement does
not cause the valve to go to fail-safe position if the safety
signal is operating correctly. After connections of electric
signals (FOUNDATION fieldbus and binary 24 V DC) and pneu-
matic supply the micro controller (µC) reads the input sig-
nal, position sensor (α) and pressure sensors (Ps, P1, P2 and
P3). This information is used to run the partial stroke tests
1.3 Markings
The ValvGuard is equipped with an identification plate (Fig. 2).
Identification plate markings include:
Type designation of the safety controller
Enclosure class
Revision number
Input signal (voltage range)
Input resistance
Maximum supply voltage
Supply pressure range
NOTE:
The selection and use of the ValvGuard in a specific applica-
tion 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 ser-
vicing the ValvGuard.
If you are uncertain about the use of the controller or its
suitability for your intended use, please contact Metso’s
Automation business for more information.
NOTE:
Micro controller is only able to control the prestage if
safety signal is present (24 V DC). Micro controller can
never prevent the safety action to happen since safety
action is the same as there’s no voltage in the safety signal
line.

1.5 Recycling and disposal
Most ValvGuard parts can be recycled if sorted according to
material.
Most parts have material marking. A material list is supplied
with the ValvGuard. In addition, separate recycling and dis-
posal instructions are available from the manufacturer.
A ValvGuard may also be returned to the manufacturer for
recycling and disposal. There will be a charge for this.
1.6 Safety precautions
CAUTION:
Opening the cover of VG9000F field device enclosure
is allowed for authorized and trained persons only!
Misuse of powered VG9000F field device may cause a dan-
gerous situation.
CAUTION:

the device is vulnerable to e.g. salt water.
CAUTION:
Do not exceed the permitted values!
Exceeding the permitted values marked on the ValvGuard
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 equip-
ment 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 ValvGuard leads to uncontrolled pressure
release. Always shut off the supply air and release the
pressure from the pipelines and equipment before remov-
ing or dismantling the controller. Otherwise personal
injury and damage to equipment may result.

2 TRANSPORTATION, RECEPTION AND
STORAGE
The safety controller is a sophisticated instrument, handle it
with care.
Check the controller for any damage that may have
occurred during transportation.
Store the controller preferably indoors, keep it away
from rain and dust.
Do not unpack the device until installing it.
Do not drop or knock the controller.
Keep the flow ports and cable glands plugged until
installing.
Follow instructions elsewhere in this manual.
3 MOUNTING
3.1 General
If the ValvGuard is supplied with valve and actuator, the
tubes are mounted and the ValvGuard adjusted in accord-
ance with the customer’s specifications.
The controller is equipped for connection according to VDI/
VDE 3845.
Shaft coupling alternatives for the controller for Metso
actuators are shown in Fig. 4.
For mounting parts for Metso actuators, see 11.3 - 11.5.
3.2 Mounting on Metso actuators
with VDI/VDE mounting face
See figures in Section 11.3.
Mount the H-shaped coupling (47) to the shaft.
Apply the thread-locking compound to the screw
(48) and tighten firmly.
Remove all protective plastic plugs from the pneu-
matic connections.
BJ and other single acting actuators: mount a metal
plug (53) with sealant to the C1 connection.
Set the direction arrow of the actuator in the direc-
tion of the valve closure member and attach the ear
(2) to the indicator cover in the position shown in
Section 11.3. Secure the screw of the ear using e.g.
Loctite and tighten firmly.
Attach the bracket (1) to the ValvGuard.
Attach the bracket (1) to the actuator. The shaft cou-
pling of the ValvGuard must fit into the ear (2) so that
the pointer is located in the position shown in Fig.3.
3.3 Mounting on linear actuator with
IEC 60534 mounting face
See figure in Section 11.5
Attach the feedback arm with spacer to the control-
ler shaft. Note the position of the pointer on the
shaft as in 11.5. Apply thread locking compound to
the screws and tighten firmly. Attach the spring to
the feedback arm as shown in Section 11.5.
Mount the controller mounting bracket loosely to
the yoke of the actuator.
Remove all plastic plugs from all actuator connec-
tions (3 pcs.).
Mount the controller loosely to the mounting
bracket guiding the pin on the actuator stem to the
slot of the feedback arm.
Align the bracket and the controller with the actua-
tor stem and adjust their position so that the feed-
back arm is approximately at a 90° angle to the
actuator stem (in the mid-stroke position).
Tighten the controller mounting bracket screws.
Adjust the distance of the controller 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 11.5. Best control performance is
achieved when the feedback lever utilises the maxi-
mum allowed angle (±45° from horizontal position).
The whole range should be at least 45°.
Make sure that the controller is in right angle and
tighten all the mounting bolts.
Ensure 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
cut to size.
NOTE:
The enclosure of ValvGuard meets the IP66 protection
class according to EN 60529. Cable entry needs to be
plugged according to IP66 and it is not allowed to mount
the ValvGuard in a position where the cable entry is point-
ing upwards.
Based on good mounting practice, the recommended
mounting position is electrical connections placed down-
wards. 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 ValvGuard or other
electrical instrumentation, our warranty is not valid.
NOTE:
Special care must be taken that the shaft position has
been set according to marking in VG9000F housing and
the pointer in the shaft. Also make sure that the positioner
fail action parameter (PFA) is set correctly (Section 4.4.3).

Apply grease (Molykote or equivalent) to the contact
surfaces of the actuator pin and the feedback arm to
reduce wear.
3.4 Mounting and installation of VG9300
Mounting bracket
Make sure the mounting bracket is suitable for the
weight of the device. See detailed weight informa-
tion in Section 1.5.
Three extra M8 mounting holes exist in the standard
mounting face of the housing for additional support.
See dimension drawings for VG9300 in pages 40-41
(Chapter 12). The use of this extra support is manda-
tory in addition to the standard mounting face.
There are also two 6.5 mm holes for additional sup-
port when needed. See dimension drawings for
VG9300 in Chapter 12.
Pipeline support
Due to the extra weight of stainless steel version
and/or possible heavy vibration, make sure there are
proper supports in the pipeline to hold the weight of
the valve assembly.
Spool valve protective cover
The spool valve protective cover (454) has 2 pcs. of
1/2” NPT threaded openings.
Openings allow an adequate exhaust capacity and
breathing of the spool valve.
Openings have breathers (456) installed, but they
can be replaced with protective piping if needed
and when necessary.
If VG is installed vertically, it is recommended to
replace the breather with protective piping in the
opening pointing upwards.
Exhaust adapter
The exhaust adapter (8) has a 1/2” NPT threaded
opening.
Opening allows an excess air to be released from the
housing and to prevent overpressurization.
Exhaust adapter has a breather (456) installed, but it
can be replaced with protective piping if needed
and when necessary.
Opening in the exhaust adapter shall not be
plugged!
Protective piping
Piping of the spool valve cover and/or exhaust
adapter shall be done in cases where it is assumed
that water can go inside the spool valve cover or into
the exhaust adapter in spite of breathers.
Piping shall be done so that the blowing of the exhaust
air is downwards and to prevent water to go inside the
protective cover or the exhaust adapter.
Minimum inside diameter of the piping is 13 mm.
Exhaust adapter piping shall not be connected to
the spool valve cover piping!
NOTE:
Special care must be taken that the shaft position has
been set according to marking in VG9000F housing and
the pointer in the shaft. Also make sure that the positioner
fail action parameter (PFA) is set correctly (Section 4.4.3).

3.5 Piping
Table 3 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.
Connect the air supply to S. Connect C1 and C2 to the actu-
ator, see Fig. 5. C1 must be plugged if single-acting actua-
tor.
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 1.4.
CAUTION:
Do not exceed the permitted supply pressure of the
ValvGuard!
CAUTION:
The stroking times mentioned in Table 3 are trendset-
ting. They are measured with 5 bar supply air pressure,
but may vary significantly due to different factors
such as, but not limited to, pressure difference of the
valve, the stiction of the actuator, supply air pressure,
the capacity of the supply air system and the dimen-
sions of the supply air pipeline.
NOTE:
When opening/closing times are defined in the Table 3,
the specified spool valve size can be used with that actua-
tor size. If there is '-' sign in the table or if smaller actuators
than shown in the table are used, please contact Metso.
NOTE:
When faster speeds are needed than shown in the table,
QEV or volume booster can be used. Bypass valve is man-
datory with volume boosters and QEV. Contact Metso for
separate instrumentation diagrams and instructions.
NOTE:
When QEV or volume booster is used, VG with standard
spool valve (VG9_15_) is required.
NOTE:
An excess of sealant may result in faulty operation of the
controller.
Sealing tape is not recommended.
Do not exceed torque of 30 Nm/22 lbf ft when fitting
1/4" NPT connectors to C1, C2 and S (VG921_).
Ensure that the air piping is clean.
NOTE:
A ValvGuard mounted on a spring actuator must be con-
nected only as single-acting. See Fig. 5.

QPX_C 4.1 / 60
QPX_D 5.5 / 80
Adjust regulator pressure to a level that is max 1 bar (14.5 psi)
+ spring rate.
CAUTION:
The air supply system must be of sufficient size and
capacity to ensure that at maximum flow during valve
movement the pressure at the ValvGuard must not fall
below 3 bar. Also note that if the air supply system
allows the pressure at the ValvGuard to fall below the
actuator minimum supply pressure during valve
movement the stroke speed will be affected.

4 LOCAL USER INTERFACE (LUI)
The local user interface may be used to monitor the device
behaviour as well as configuring and commissioning the
controller during installation and normal operation. The
local user interface consists of two row LCD and four button
keypad interface. There are also custom graphical charac-
ters 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 4 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 selection by
pressing +or -while keeping the ?key pressed down.
When the buttons are released the current 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 measurements will
start scrolling on the display. This enables the user to view
all the measurements through the window of the main
cover.
Valve position (POS) shows the valve travel position in per-
centage (%) of full scale. Optional unit is angle.
Input signal (INP) shows if the 24 V DC input signal is con-
nected (On) or not (OFF).
Actuator pressure difference (PDIF) shows the actuator
pressure in single acting actuators or pressure difference in
double acting actuators in bars (BAR). Optional unit is psi
(PSI).
Housing pressure (Pint) shows the pressure inside the
enclosure in bars (BAR).
Supply pressure (SUPL) shows the air supply pressure
value in bars (BAR). Optional unit is psi (PSI).
Device temperature (TEMP) shows the temperature inside
the device in degree Celsius (C). Optional unit is degree
Fahrenheit (F).
Device usage (USAG) shows if the device is set to operate
as safety (SAF) device, On/Off (Ono) device or Hybrid (HYb)
device.

Safety usage means that FOUNDATION fieldbus powers
up the diagnostic part of the device and emergency
action is implemented by the safety system signal.
On/Off usage means that FOUNDATION fieldbus pow-
ers up the diagnostic part of the device, and on/off
action is implemented by the 24 V DC signal from
the DCS. Device is not intended to be used as a
safety device. All closing actions are considered as
normal valve operations. However, the SIL certificate
is valid even if used in On/Off-mode.
Hybrid usage means that VG9000F can perform nor-
mal on/off valve operation (i.e. closing or opening)
or Partial Stroke Test (PST) through FOUNDATION field-
bus communication. In this way the DCS can control
the valve opening/closing and PST implementation
and the safety system controls the safety action
implementation.
NOTE: Default value is safety device.
NOTE: Device usage can only be changed via DD, i.e. using
fieldbus configurator.
4.2 Guided start-up
Guided startup offers a fast view of the most critical param-
eters of the ValvGuard controller, actuator and valve config-
uration. After verifying the parameters the valve travel
calibration is recommended. The guided start-up is entered

If you modify any of the parameters you will also need to
calibrate the device. See 4.5 for detailed description.
4.3 Configuration menu
The local user interface is organised in a menu structure. 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 Configuration parameters
When PAR is on the display you may enter the configura-
tion menu by pressing the ?key. In this menu the most
important configuration and signal modification parame-
ters are viewable. Depending on the device usage option
selected (safety, on/off, hybrid) the menu has different
parameters, see Figures 11–13. NOTE: Device usage option
can not be selected from LUI, only from DD. You may view
the current value and edit them by pressing the ?key at
the relevant parameter. The name of the parameter will
appear on the upper row of the display and the current

Pressure' -parameter needs to be set to negative value,
e.g. -2. It can only be changed via FOUNDATION fieldbus, e.g.
in the DTM.
NOTE:
Pneumatics test (Section 4.6.2.) will be run automatically
before the partial stroke test in some cases, e.g. when sup-
ply pressure has changed. Pneumatics test timeout
parameter is valid also in this case.
NOTE:
Pneumatics test will check the pneumatics function of the
device by moving the spool valve only and not moving
the actuator or the valve.
NOTE:
Valve position needs to be in the normal operating posi-
tion, supply pressure needs to be in valid range and any
other test or calibration cannot be active when testing is
started.
NOTE:
Pneumatics test timeout parameter is 600 s. The value is
hardcoded and cannot be changed.

4.9 Special displays
4.9.1 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 prohib-
ited. You may lock and unlock the device only via FOUNDA-
TION fieldbus DD. When the Local User Interface is locked
the lock symbol will be activated on the display.
4.9.2 Alarm or warning state
All failure conditions and statuses in VG9000F can be indi-
vidually configured to three different classes: Alarm, Warn-
ing or Info, or they can be ignored. This configuration can
be done with DTM (see separate DTM manual). Alarm state
causes a blinking & to be shown on the display. In Warn-
ing state, the &symbol is steady.
4.9.3 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 display 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.
4.9.4 Write protection
The VG9000F is delivered from the factory with HW write
protection OFF as the default setting. Reading and chang-
ing parameters is thus allowed. Write protection can be
enabled with the switch (DIP1) located on the circuit board
(see Fig. 20). If you need to change the setting, please con-
tact Metso’s Automation business for instructions.
Write protection protects all write access to all writeable
parameters of the device. Changing the parameters from
the LUI, fieldbus configurator or FieldCare is thus not
allowed.

4.9.5 Simulation switch
The VG9000F is delivered from the factory with Simulation
switch OFF (disabled). Simulation can be enabled with the
switch (DIP2) located on the circuit board (see Fig. 20). If
you need to change the setting, please contact Metso’s
Automation business for instructions.
Enable state of Simulation allows user to simulate valve
position measurement (via AI block) and field diagnostic
conditions (via Resource Block).
5 MAINTENANCE
The maintenance requirements of the ValvGuard depend
on the service conditions, for instance, the quality of instru-
ment air. Under normal service conditions there is no
requirement for regular maintenance.
When maintaining the ValvGuard 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 11, unless other-
wise stated.
The ValvGuard VG9000F includes the following modules:
prestage unit (120), spool valve (420), communication cir-
cuit board 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 cover (100).
In the event of failure the whole module must be changed.
The module retrofit must be assembled in a clean, dry envi-
ronment. On reassembly apply a thread-locking compound
(for instance, Loctite 243) and tighten the screws firmly.
5.1 Opening and closing of the cover
Open VG9000F cover (100) by opening the M4 screw
(107) first until it is not anymore attached to the
housing (2). Then turn the cover counterclockwise
until it can be removed.
Close the cover (100) in reverse order. Mount it first
on top of the housing (2) and then turn it clockwise
until threads are tight and the screw (107) is facing
the spring (111) in the housing (2). Tighten the M4
screw (107).
5.2 Prestage
5.2.1 Removal
Loosen the M8 stop screw (110) in the position indi-
cator (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 con-
nector board (182). Unscrew the M4 screws (139, 2
pcs.) and lift up the prestage unit (120). Remove the
O-ring (140).
5.2.2 Adapter plate removal
Remove the screw (412) and remove the adapter
plate. Adapter plate is only needed to be removed
when replaced with new one.
5.2.3 Installation
Install the new adapter plate, if it has been removed.
Make sure the O-rings (411) are properly installed.
Tighten the screw (412).
Place a new O-ring (140) into the groove in the pre-
stage mounting plate (400) 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 correct position. Tighten the screws (139)
evenly.
Push the prestage 2-pole wire connector into the
socket on the connector board (182). The wire con-
nector can only be fitted in the correct position.
Replace the inner cover (39) and tighten the M3
screws.
