2 General Information
The following instructions are designed to assist in unpacking,
installing and performing maintenance as required on Valtek
3200MD digital positioners. Series 3000 is the term used for all
the positioners herein; however, specifi c numbers indicate features
specifi c to model (i.e., Logix 3200 indicates that the positioner has
®
HART
protocol). See Logix 3200MD Model Number table in this
manual for a breakdown of specifi c model numbers. Product users
and maintenance personnel should thoroughly review this bulletin
prior to installing, operating, or performing any maintenance on the
valve.
Separate Valtek Flow Control Products Installation, Operation,
Maintenance instructions cover the valve (such as IOM 1 or IOM 27)
and actuator (such as IOM 2 or IOM 31) portions of the system and
other accessories. Refer to the appropriate instructions when this
information is needed.
To avoid possible injury to personnel or damage to valve parts,
WARNING and CAUTION notes must be strictly followed. Modifying
this product, substituting non-factory parts or using maintenance
procedures other than outlined could drastically affect performance
and be hazardous to personnel and equipment, and may void existing warranties.

WARNING: Standard industry safety practices must be
adhered to when working on this or any process control
product. Specifi cally, personal protective and lifting devices
must be used as warranted.
WARNING: Substitution of components may impair intrin-
sic safety.
3 Unpacking and Storage
3.1 Unpacking
1. While unpacking the Logix 3200MD positioner, check the
packing list against the materials received. Lists describing the
system and accessories are included in each shipping
container.
2. When lifting the system from the shipping container, position
lifting straps to avoid damage to mounted accessories. Systems
with valves up to six inches may be lifted by actuator lifting ring.
On larger systems, lift unit using lifting straps or hooks through
the yoke legs and outer end of body.
WARNING: When lifting a valve/actuator assembly with
lifting straps, be aware the center of gravity may be above
the lifting point. Therefore, support must be given to prevent the valve/actuator from rotating. Failure to do so can
cause serious injury to personnel or damage to nearby
equipment.
3. In the event of shipping damage, contact the shipper
immediately.
4. Should any problems arise, contact a Flowserve Flow Control
Division representative.
3.2 Storage
Control valve packages (a control valve and its instrumentation)
can be safely stored in an enclosed building that affords environmental protection; heating is not required. Control valve packages
must be stored on suitable skids, not directly on the fl oor. The
storage location must also be free from fl ooding, dust, dirt, etc.
3.3 Pre-installation Inspection
If a valve control package has been stored for more than one year,
inspect one actuator by disassembling it per the appropriate Installation, Operation, and Maintenance Instructions (IOM) prior to valve
installation. If O-rings are out-of-round, deteriorated, or both, they
must be replaced and the actuator rebuilt. All actuators must then
be disassembled and inspected. If the actuator O-rings are replaced,
complete the following steps:
1. Replace the pressure-balance plug O-rings.

4 Logix 3200MD
Positioner Overview
The Logix 3200MD digital positioner is a two-wire 4-20 mA input digital
valve positioner. The positioner is confi gurable through the local user
interface. The Logix 3200MD utilizes the HART protocol to allow twoway remote communications with the positioner. The Logix 3200MD
positioner can control both double- and single-acting actuators with
linear or rotary mountings. The positioner is completely powered by
the 4-20 mA input signal. Start up current must be at least 3.6 mA
without AO card or 3.85 mA with AO card.

4.2 Positioner Operation
The Logix 3200MD positioner is an electric feedback instrument.
Figure 1 shows a Logix 3200MD positioner installed on a doubleacting linear actuator for air-to-open action.
The Logix 3200MD receives power from the two-wire, 4-20 mA
input signal. However, since this positioner utilizes HART communications, two sources can be used for the command signal:
Analog and Digital. In Analog source, the 4-20 mA signal is used for
the command source. In Digital source, the level of the input 4-20
mA signal is ignored and a digital signal, sent via HART, is used as
the command source. The command source can be accessed with
ValveSight software, the HART 375 communicator, or other host
software.
Whether in Analog or Digital Source, 0% is always defi ned as the
valve closed position and 100% is always defi ned as the valve
open position. In Analog Source, the 4-20 mA signal is converted
to a percentage. During loop calibration, the signals corresponding
to 0% and 100% are defi ned. The input signal in percent passes
through a characterization/limits modifi er block. The positioner no
longer uses CAMs or other mechanical means to characterize the
output of the positioner. This function is done in software, which
allows for in-the-fi eld customer adjustment. The positioner has three
basic modes: Linear, Equal Percent (=%) and Custom characteriza-
tion. In Linear mode, the input signal is passed straight through to
the control algorithm in a 1:1 transfer. In Equal Percent (=%) mode,
the input signal is mapped to a standard 30:1 rangeability =% curve.
If Custom characterization is enabled, the input signal is mapped to
either a default =% output curve or a custom, user-defi ned 21-point
output curve. The custom user-defi ned 21-point output curve is
defi ned using a handheld or ValveSight software. In addition, two
user-defi ned features, Soft Limits and MPC (Minimum Position
Cutoff), may affect the fi nal input signal. The actual command being
used to position the stem, after any characterization or user limits
have been evaluated, is called the Control Command.
The Logix 3200MD uses a two-stage, stem-positioning algorithm.
The two stages consist of an inner-loop, spool control and an outerloop, stem position control. Referring again to Figure 1, a stem
position sensor provides a measurement of the stem movement.
The Control Command is compared against the Stem Position. If
any deviation exists, the control algorithm sends a signal to the
inner-loop control to move the spool up or down, depending upon
the deviation. The inner-loop then quickly adjusts the spool position.
The actuator pressures change and the stem begins to move. The
stem movement reduces the deviation between Control Command
and Stem Position. This process continues until the deviation goes
to zero.
The inner-loop controls the position of the spool valve by means of
a driver module. The driver module consists of a temperature-compensated hall effect sensor and a piezo valve pressure modulator.

The piezo valve pressure modulator controls the air pressure under
a diaphragm by means of a piezo beam bender. The piezo beam
defl ects in response to an applied voltage from the inner-loop electronics. As the voltage to the piezo valve increases, the piezo beam
bends, closing off against a nozzle causing the pressure under
the diaphragm to increase. As the pressure under the diaphragm
increases or decreases, the spool valve moves up or down respectively. The hall effect sensor transmits the position of the spool back
to the inner-loop electronics for control purposes.
4.3 Detailed Sequence
of Positioner Operations
A more detailed example explains the control function. Assume the
unit is confi gured as follows:
• Unit is in Analog command source.
• Custom characterization is disabled (therefore characterization is
Linear).
• No soft limits enabled. No MPC set.
• Valve has zero deviation with a present input signal of 12 mA.
• Loop calibration: 4 mA = 0% command, 20 mA = 100% com-
mand.
• Actuator is tubed and positioner is confi gured air-to-open.
Given these conditions, 12 mA represents a Command source of
50 percent. Custom characterization is disabled so the Command source is passed 1:1 to the Control Command. Since zero deviation
exists, the Stem Position is also at 50 percent. With the stem at the
desired position, the spool valve will be at a middle position that balances the pressures above and below the piston in the actuator. This
is commonly called the null or balanced spool position.
Assume the input signal changes from 12 mA to 16 mA. The positioner sees this as a Command source of 75 percent. With Linear characterization, the Control Command becomes 75 percent. Deviation is the difference between Control Command and Stem Position :
Deviation = 75% - 50% = +25%, where 50 percent is the present
stem position. With this positive deviation, the control algorithm
sends a signal to move the spool up from its present position. As the
spool moves up, the supply air is applied to the bottom of the actuator and air is exhausted from the top of the actuator. This new pressure differential causes the stem to start moving towards the desired
position of 75 percent. As the stem moves, the Deviation begins to
decrease. The control algorithm begins to reduce the spool opening.
This process continues until the Deviation goes to zero. At this point,
the spool will be back in its null or balanced position. Stem movement will stop and the desired stem position is now achieved.
One important parameter has not been discussed to this point: Inner
loop offset. Referring to Figure 2, a number called Inner loop offset
is added to the output of the control algorithm. In order for the spool
to remain in its null or balanced position, the control algorithm must
output a non-zero spool command. This is the purpose of the Inner loop offset. The value of this number is equivalent to the signal that
must be sent to the spool position control to bring it to a null position with zero deviation. This parameter is important for proper control and is optimized and set automatically during stroke calibration.

4. Screw one mounting bolt into the hole on the yoke mounting
pad nearest the cylinder. Stop when the bolt is approximately
3
⁄16" from being fl ush with mounting pad.
5. Slip the large end of the teardrop shaped mounting hole in the
back of the positioner/bracket assembly over the mounting bolt.
Slide the small end of the teardrop under the mounting bolt and
align the lower mounting hole.
6. Insert the lower mounting bolt and tighten the bolting.
7. Position the take-off arm mounting slot against the stem clamp
mounting pad. Apply Loctite 222 to the take-off arm bolting and
insert through washers into stem clamp. Leave bolts loose.
8. Slide the appropriate pin slot of the take-off arm, based on
stroke length, over the follower arm pin. The appropriate stroke
lengths are stamped by each pin slot.
9. Center the take-off arm on the rolling sleeve of the follower pin.
10. Align the take-off arm with the top plane of the stem clamp and
tighten bolting. Torque to 120 in-lb.
! NOTE: If mounted properly, the follower arm should be
hole pattern as indicated on
horizontal when the valve is at 50% stroke and should move
approximately ±30° from horizontal over the full stroke of the
valve. If mounted incorrectly, a stroke calibration error will
occur and the indicator lights will blink a RGGY code indicating
the position sensor has gone out of range on one end of travel.
Reposition the feedback linkage or rotate the position sensor to
correct the error.
5.2 Mounting to Standard
Valtek Rotary Valves
(See Figure 4)
The standard rotary mounting applies to Valtek valve/actuator assemblies that do not have mounted volume tanks or handwheels.
The standard mounting uses a linkage directly coupled to the valve
shaft. This linkage has been designed to allow for minimal misalignment between the positioner and the actuator. The tools required for
the following procedure are:
5
•
⁄32" Allen wrench
• ½ " open-end wrench
7
•
⁄16" open-end wrench

1. Fasten the spline lever adapter to the splined lever using two 6 x
½ " self-tapping screws.
2. Slide the take-off arm assembly onto the spline lever adapter
shaft. Insert the screw with star washer through the take-off
arm and add the second star washer and nut. Tighten nut with
socket so arm is lightly snug on the shaft but still able to rotate.
This will be tightened after linkage is correctly oriented.
3. Attach follower arm to positioner feedback shaft using the star
washer and 10-32 nut.
! NOTE: The arm will point up when feedback shaft is in the free
position.
4. Using four ¼ -20 x ½ " bolts, fasten positioner to universal
bracket using appropriate hole pattern (stamped on bracket).
5. Using a ½ " end wrench and two
to actuator transfer case pad. Leave these bolts slightly loose
until fi nal adjustments are made.
6. Rotate take-off arm so the follower pin will slide into the slot on
the take-off arm. Adjust the bracket position as needed noting
the engagement of the follower pin and the take-off arm slot.
User Instructions - Digital Positioner 3200MD LGENIM0059-09 12/13
The pin should extend approximately 1⁄16" past the take-off arm.
When properly adjusted, securely tighten the bracketing bolts.
Orienting the Take-off Arm for Final Lock Down
1. Tube the Logix 3200MD positioner to the actuator according
to the instructions given in Section 5.5, “Tubing Positioner to
Actuator.”
2. With supply pressure off, rotate the follower arm in the same
direction the shaft would rotate upon a loss of supply pressure.
When the mechanical stop of the follower arm (positioner) is
reached, rotate back approximately 15 degrees.
3. Hold the take-off arm in place; tighten the screw of the take-off
arm.
! NOTE: The take-off arm should be snug enough to hold the
follower arm in place but allow movement when pushed.
4. Connect regulated air supply to appropriate port in manifold.
5. Remove main cover and locate DIP switches and QUICK-CAL
button.
6. Refer to sticker on main board cover and set DIP switches
accordingly. (A more detailed explanation of the DIP switch
settings is given in Section 7, “Startup.”)
7. Press the QUICK-CAL button for three to four seconds or
until the positioner begins to move. The positioner will now
perform a stroke calibration.
8. If the calibration was successful the green LED will blink GGGG
or GGGY and the valve will be in control mode. Continue with
step 9. If calibration failed, as indicated by a RGGY blink code,
the A/D feedback values were exceeded and the arm must be
adjusted away from the positioners limits. Return to step 2 and
rotate the arm back approximately 10 degrees.
! NOTE: Remember to remove the air supply before re-adjusting
take-off arm.
9. Tighten the nut on the take-off arm. The socket head screw of
the take-off arm must be tight, about 40 in-lb.
! NOTE: If the take-off arm slips, the positioner must be
recalibrated.
WARNING: Failure to follow this procedure will result in
positioner and/or linkage damage. Check air-action and
stroke carefully before lockdown of take-off arm to spline
lever adapter.

5.4 NAMUR Rotary Mounting
The Logix 3200MD includes an option for NAMUR Rotary mounting.
The NAMUR shaft option provides mounting to standard brackets
for valve automation. The NAMUR option is not recommended for
high performance valves since the normal alignment tolerances can
cause a degradation in valve performance. Care must be taken when
mounting the positioner using a NAMUR confi guration to prevent
damage to the shaft. Mount the positioner and rotate into position
using the following table:

5.5 Tubing Positioner to Actuator
The Logix 3200MD digital positioner is insensitive to supply pressure changes and can handle supply pressures from 30 to 150 psig.
A supply regulator is recommended if the customer will be using
the diagnostic features of the Logix 3200MD but is not required. In
applications where the supply pressure is higher than the maximum
actuator pressure rating a supply regulator is required to lower the
pressure to the actuator’s maximum rating (not to be confused with
operating range). An air fi lter is highly recommended for all applications where dirty air is a possibility.
! NOTE: The air supply must conform to ISA Standard ISA 7.0.01
(a dew point at least 18°F below ambient temperature, particle
size below fi ve microns—one micron recommended—and oil
content not to exceed one part per million).
Air-to-open and air-to-close are determined by the actuator tubing,
not the software. When air action selection is made during confi guration, that selection tells the control which way the actuator
has been tubed. The top output port is called Output 1. It should be
tubed to the side of the actuator that must receive air to begin the
correct action on increasing signal. Verify that tubing is correct prior
to a stroke calibration. Proper tubing orientation is critical for the
positioner to function correctly and have the proper failure mode.
Refer to Figure 5 and follow the instructions below:
Linear Double-acting Actuators
For a linear air-to-open actuator, the Output 1 port of the
positioner manifold is tubed to the bottom side of the actuator.
The Output 2 port of the positioner manifold is tubed to the top
side of the actuator. For a linear air-to-close actuator the above
confi guration is reversed.
Rotary Double-acting Actuators
For a rotary actuator, the Output 1 port of the positioner manifold
is tubed to the bottom side of the actuator. The Output 2 port of
the positioner manifold is tubed to the top side of the actuator.
This tubing convention is followed regardless of air action. On
rotary actuators, the transfer case orientation determines the air
action.
Single-acting Actuators
For single-acting actuators, the Output 1 port is always tubed to the
pneumatic side of the actuator regardless of air action. The Output 2
port must be plugged.

(See Figure 6)
WARNING: This product has electrical conduit connec-
tions in either thread sizes ½ " NPT or M20 which appear
identical but are not interchangeable. Housings with
M20 threads are stamped with the letters M20 above
the conduit opening. Forcing dissimilar threads together
will damage equipment, cause personal injury and void
hazardous location certifi cations. Conduit fi ttings must
match equipment housing threads before installation. If
threads do not match, obtain suitable adapters or contact
a Flowserve representative.
6.1 4-20 mA Command Input Wiring
Verify polarity when making fi eld termination connection. The Logix
3200 is reverse polarity protected. Wire 4-20 mA current source to
the input terminal labeled 4-20 mA Input on the user interface board
(See Figure 6). Never connect a voltage source directly across the
Logix 3200MD terminals. The current must always be limited for
4-20 mA operation. Minimum operating current is 3.6 mA.
User Instructions - Digital Positioner 3200MD LGENIM0059-09 12/13
Output compliance voltage refers to the voltage limit that can be
provided by the current source. A current loop system consists of
the current source, wiring resistance, barrier resistance (if present),
and the Logix 3200MD positioner impedance. The Logix 3200MD
digital positioner requires that the current loop system allows for
a 10.0 VDC drop across the positioner at maximum loop current.
The 10.0 VDC drop across the Logix 3200MD positioner terminals
is generated by the positioner from the 4-20 mA loop current input.
The actual voltage at the terminals varies from 9.8 to 10.0 VDC
depending on the current mA signal, HART communications, and
ambient temperature.

Terminals (Optional)
The input loop current signal to the Logix 3200MD digital positioner
should be in shielded cable. Shields must be tied to a ground at only
one end of the cable to provide a place for environmental electrical
noise to be removed from the cable. In general, shield wire should
be connected at the source.
! NOTE: The Logix 3200MD positioner carries an intrinsically safe
barrier rating of 100 mA. Input currents should not exceed 100
mA.
6.2 Grounding Screw
The green grounding screw, located inside the termination cap,
should be used to provide the unit with an adequate and reliable
earth ground reference. This ground should be tied to the same
ground as the electrical conduit. Additionally, the electrical conduit
should be earth grounded at both ends of its run.
WARNING: The green grounding screw must not be used
to terminate signal shield wires.

The voltage 12.5 VDC is greater than the required 10.0 VDC; therefore, this system will support the Logix 3200MD digital positioner.
The Logix 3200MD positioner has a worst case input resistance
equivalent to 500 Ω at a 20 mA input current.
6.4 Cable Requirements
The Logix 3200MD digital positioner utilizes the HART Communication protocol. This communication signal is superimposed
on the 4-20 mA current signal. The two frequencies used by the
HART protocol are 1200 Hz and 2200 Hz. In order to prevent
distortion of the HART communication signal, cable capacitance
and cable length restrictions must be calculated. The cable length
must be limited if the capacitance is too high. Selecting a cable
with lower capacitance/foot rating will allow longer cable runs.
In addition to the cable capacitance, the network resistance also
affects the allowable cable length.

6.5 Intrinsically Safe Barriers
When selecting an intrinsically safe barrier, make sure the barrier is
HART compatible. Although the barrier will pass the loop current and
allow normal positioner control, if not compatible, it may prevent
HART communication.

7.1 Logix 3200MD Local Interface
Operation
The Logix 3200MD local user interface allows the user to confi gure
the basic operation of the positioner, tune the response, and calibrate
the positioner without additional tools or confi gurators. The Local
interface consists of a quick calibration button for automatic zero
and span setting, along with two jog buttons for spanning valve/
actuators with no fi xed internal stop in the open position. There is
also a switch block containing 8 switches. Six of the switches are
for basic confi guration settings and one is for calibration options.
There is also a gain selector switch for adjusting the positioner gain
settings. For indication of the operational status or alarm conditions
there are also 3 LEDs on the local user interface.

LinearSelect if the actuator position should be directly proportional
to the input signal. (Due to their inherent =% characteristics, this
setting give an =% Cv characteristic for most rotary valves.)
Optional Select if another characteristic is desired, which is set in
conjunction with the next switch, labeled Optional Pos. Char.
Optional Pos. Characterization
If the Pos. Characterization switch is set to optional then this switch
is active with the following options:
The =% option will characterize the actuator response to the input
signal based on a standard 30:1 equal percent rangability curve
Custom If Custom is selected, the positioner will be characterized
to a custom table that must be setup using a properly confi gured
HART 275 handheld or other host software. The Default setting for
this curve is modifi ed quick open. ( also used for a linear Cv characteristic for most rotary valves)
This switch controls whether the positioner will auto tune itself or
use preset tuning parameters.
On On enables an auto tune feature that will automatically deter-
mine the positioner gain settings based on the current position of the
selectable “Gain” switch setting and response parameters measured
during the last QUICK-CAL. The gain switch is live meaning the
settings can be adjusted at any time by changing the selectable gain
switch position. (

If the adjustable GAIN selector switch is set to “F”, “G”, or “H” with
the auto tune switch on, progressively higher gain settings will be
calculated and used based on response parameters measured during
the last QUICK-CAL.
If the selectable GAIN switch is set to “A” the tuning will not be
modifi ed with a QUICK-CAL. Use this setting if custom tuning will
be done using a handheld or other Flowserve software.

User Instructions - Digital Positioner 3200MD LGENIM0059-09 12/13
Off Off forces the positioner to use one of the factory
preset tuning sets determined by the rotary “Gain” selector
switch. Settings “A” through “H” are progressively higher
gain predefi ned tuning sets. The Gain selector switch can be
adjusted at any time to modify the tuning parameters.
! NOTE: With Autotune on “E” is the default adjustable GAIN
selector switch setting for all actuator sizes. Raising or lowering
the gain setting is a function of the positioner/valve response to
the control signal, and is not actuator size dependent.
Spare Switch
If special features have been purchased they may be controlled
by this switch. See special documentation for more details.
Stability Switch
This switch adjusts the position control algorithm of the positioner
for use with low-friction control valves or high-friction automated
valves.
Placing the switch to the left optimizes the response for low friction,
high performance control valves. This setting provides for optimum
response times when used with most low friction control valves.
Placing the switch to the right optimizes the response for valves
and actuators with high friction levels. This setting slightly slows
the response and will normally stop limit cycling that can occur
on high friction valves.
! NOTE: This option is more effective on advanced units with the
optional pressure sensors installed.
7.4 Setup of the Cal Dip-Switch for the
Quick Calibration Operating Mode.
The eighth DIP switch selects between two calibration options. The
function of the Cal DIP switch is described below.
Auto Select Auto if the valve/actuator assembly has an internal
stop in the open position. In Auto mode the positioner will fully
close the valve and register the 0% position and then open the valve
to the stop to register the 100% position when performing a selfcalibration. See detailed instructions in the next section on how to
perform an auto positioner calibration.
Jog Select Jog if the valve/actuator assembly has no calibration
stop in the open position. In the Jog mode the positioner will fully
close the valve for the 0% position and then wait for the user to set
the open position using the Jog buttons labeled with the up and
down arrows. See the detailed instructions in the next section on
how to perform a manual calibration using the “Jog” buttons.
WARNING: During the QUICK-CAL operation the valve may
stroke unexpectedly. Notify proper personnel that the valve
will stroke, and make sure the valve is properly isolated.
7.5 QUICK-CAL Operation
The QUICK-CAL button is used to locally initiate a calibration of the
positioner. Pressing and holding the QUICK-CAL button for approximately 3 seconds will initiate the calibration. A QUICK-CAL can
be aborted at any time by briefl y pressing the QUICK-CAL button and
the previous settings will be retained.
If the Quick calibration switch (be careful not to confuse with the
QUICK-CAL button) is set to Auto and the valve/actuator assembly has the necessary internal stops the calibration will complete
automatically. While the calibration is in progress you will notice a
series of different lights fl ashing indicating the calibration progress.
When the lights return to a sequence that starts with a green light
the calibration is complete. (See the table X for an explanation of the
various light sequences) The initial calibration of extremely large
or very small actuators may require several calibration attempts.
The positioner adapts to the actuator performance and begins each
calibration where the last attempt ended. On an initial installation it
is recommended that after the fi rst successful calibration that one
more calibration be completed for optimum performance.
If the Quick ca
initially close the valve then cause a small jump in the valve
position. The jog calibration process will only allow the user to
manually set the span; zero position is automatically always set
at the seat. If an elevated zero is needed a handheld or other PC
based confi guration software is required.
When performing a jog calibration the LED‘s will fl ash in a
sequence of Y-G-Y-R (yellow-green-yellow-red) which indicates
that the user must use the jog keys to manually position the
valve to approximately 100%. When the valve is approximately
100% open press both the

7.6 Local Control of Valve Position
Local control of valve position can be done from the user
interface by holding both jog buttons while then simultaneously
pressing the quick cal button for 3 seconds. The
buttons can then be used to position the valve. While in this
mode the LED‘s will fl ash a YGYY (yellow-green-yellow-yellow)
sequence. To exit the local control mode and return to normal
operation, briefl y press the QUICK-CAL button.
WARNING: When operating using local control of the valve,
the valve will not respond to external commands. Notify
proper personnel that the valve will not respond to remote
command changes, and make sure the valve is properly
isolated
and
7.7 Factory Reset
To perform a factory reset, hold QUICK-CAL button while applying
power and all of the internal variables including calibration will be
reset to factory defaults. The positioner must be re-calibrated after
a factory reset. Tag names and other user confi gured limits, alarm
settings, and valve information will also be lost and need to be
restored.
WARNING: Performing a factory reset may result in the
inability to operate the valve until reconfi gured properly.
Notify proper personnel that the valve may stroke, and
make sure the valve is properly isolated.
7.8 Command Reset
Performing a command reset will reset the command source to
analog if it has been inadvertently left in digital mode. This is done
while a QUICK-CAL is in process by holding down both the and
buttons while briefl y pressing the QUICK-CAL button. A new
QUICK-CAL must be done after resetting.
7.9 Version number checking
The version number of the embedded code may be checked at any
time except during a calibration by holding down the button.
This will not alter the operation of the unit other than to change the
blink sequence to 3 blinks indicating the major version number.
Holding the button will give the minor version number without
affecting operation. The version codes are interpreted by adding up
the numbers assigned according to the following table:

7.10 Logix 3200MD Status Condition
The blink codes used to convey the status of the Logix 3200MD
digital positioner are described in the following table. In general,
any sequence starting with a green light fl ashing fi rst is a normal
operating mode and indicates that there are no internal problems.
Some diagnostic status results are only available with the Advanced
or Pro diagnostics option.

Diagnostic Software and HART 375
Handheld Communicator
Flowserve Corporation has written custom confi guration and
diagnostic software for the Logix 3200MD digital positioner called
ValveSight. This software is available from a Flowserve representative.
The Logix 3200MD digital positioner supports and is supported by
the HART 375 Handheld Communicator. The Device Description
(DD) fi les and the manual listed below can be obtained from the
HART Communication Foundation or from your Flowserve representative. For more information please see the following guide:
• Product Manual for the HART Communicator.
Diagnostic features such as the datalog, signature tests, and ramp
tests are performed using the ValveSight software. Certain calibration features such as loop calibration, analog output calibration, and
actuator pressure sensor calibrations are performed using the HART
375 Handheld Communicator or using diagnostic software such as
ValveSight.
!NOTE: Warnings and alarms marked by ** have been masked
from the factory. To Initiate diagnostics, perform a stroke,

the actuator can cause decreased responsiveness and excessive
air/gas consumption. Low supply pressure can also trigger this
warning.
FRICTION HIGH WARNING (user set) indicates the valve/actuator
friction has passed the user set limit. High friction can cause loop
oscillations, poor position control, jerky motion, or valve sticking.
It can be caused by build-up from the process on the stem, trim or
seat , by a failing bearing or guides in the valve and actuator,
galling of the trim or stem, excessively tightened packing, linkages,
or other valve/actuator mechanical issues.

position upon loss of signal/power. This condition may occur
briefl y on an air-to-close valve that is held for long periods of
time in the closed position, or and air-to-open valve held in the
open position.
upon loss of air supply, the valve may not move to the fail-safe
position. The spring alone is not adequate to overcome the
friction and process load in the system. The system is relying on
pneumatic force to actuate in the direction the spring is pushing.
The failsafe spring may have failed, or it was not sized properly
for the application. Friction or process load may have increased.

8.6 Stem Position Sensor
The position feedback assembly transmits valve positions information to the processor. This is accomplished by means of a rotary
position sensor that connects to the valve stem through a feedback
linkage. To provide for accurate tracking of the pin in the slot, the
follower arm is biased against one side of the slot with a rotary
spring. This spring also automatically moves the position feedback
assembly to its limit in the unlikely event of failure of any component
in the linkage.
Stem Position Sensor Replacement

8.8 Pressure Sensor Board
The pressure sensor board contains two pressure sensors that
measure the pressure on output ports 1 and 2. The actuator pressure sensors are used in the positioner control algorithm to enhance
valve stability. In positioners with Advanced diagnostics, pressure
data is gathered for supply pressure alarm, signatures and data
logging. In positioners with Pro diagnostics, pressure data is used
for full on-line diagnostic analyses. For optimal performance, the
actuator pressure sensors need to be calibrated. The actuator pressure sensor calibration is performed using a HART 375 Handheld
Communicator or confi guration software such as ValveSight.

User Instructions - Digital Positioner 3200MD LGENIM0059-09 12/13
9 Optional Hardware
9.1 Vented Design
(See Figures 19 and 20)
A standard Logix 3200MD positioner is vented directly to the atmosphere. When supply air is substituted with sweet natural gas, piping
must be used to route the exhausted natural gas to a safe environment. This piping system may cause some positioner back pressure
in the main chamber (from the modulator and regulator) and spool
chamber (from the actuator). Back pressure limitations are described
below.
Two chambers must be vented on the Logix 3200MD positioners:
the main housing chamber and the spool valve chamber (Figures 19
and 20). The main chamber vent is located on the backside of the
positioner (See Figure 19). Vented-design Logix 3200MD positioners are supplied from the factory with a fi tting installed in the main
chamber vent. Connect the necessary tubing/piping to this fi tting to
route the exhausted natural gas to a safe environment.
The maximum allowable back pressure from the collection device on
the main housing vent is 2.0 psig (0.14 barg). Vent fl ow rate is 0.5
3
std ft
/min (1.4 std liter/min).
WARNING: The back pressure in the main housing must
never rise above 2.0 psig (0.14 barg).

The spool valve chamber (See Figure 20) must also be vented
through the spool valve cover. Vented-design Logix 3200MD
positioners are supplied from the factory with a fi tting installed in
the spool valve cover (item SKU 179477). Connect the necessary
tubing/piping to this fi tting to route the exhausted natural gas to
a safe environment. The maximum allowable back pressure in the
spool valve chamber is 8 psig (0.55 barg). Pressures greater than 8
psig will cause vented gas to leak past the spool cover O-ring to the
atmosphere and will result in overshoot of the positioner.
9.2 HART Modem
The HART modem is a device that connects to the serial communications port of a computer. This modem converts the RS-232
COM port signals to the HART signal. A HART modem is optional in
ValveSight since a MUX can be used in its place. The HART modem
takes power from the RS-232 COM port lines. If using a laptop
computer running on an internal battery, HART communication may
become erratic as the batteries begin to lose charge. This is due to
a reduction in HART modem power. Allow batteries to recharge or
apply AC adapter power to the laptop to correct the problem. A HART
modem is available through your Flowserve representative. (Please
refer to Section 12 for part numbers.)
When using a HART modem with ValveSight or when using the
HART 375 handheld, the leads can be connected anywhere across
the 4-20 mA current signal. The leads are not polarity sensitive.
When using a fi lter, the connection must be made between the fi lter
output and the Logix 3200MD (See Figure 22).

9.3 4-20 mA Analog Output Board
User Instructions - Digital Positioner 3200MD LGENIM0059-09 12/13
The Logix 3200MD digital positioner can be supplied to provide an
analog feedback signal of the stem position. This option can also be
retrofi tted in the fi eld. The 4-20 mA analog output board is wired in
series with a 12.5 to 40 VDC power supply (See Figure 23). This position feedback option has the following features and specifi cations:
• Does not interfere with positioner operation.
• Calibration of the analog output signal is performed using a HART
375 Handheld Communicator or confi guration software such as
ValveSight.
• In normal operation, the ouput follows the actual position of the
valve whenever possible, including during all failure modes. During loss of power, the output of ≤ 3.15 mA is transmitted. When
confi gured with the safety annunciation feature, the current will fall
below 3.6 mA when safety critical alarms are triggered. The safety
annunciation feature is in effect if the following are both true:
1) The software version is 2.05 - 2.07, or the software version is
2.08 or later and the safety annuciation has been enabled.
2) A safety-critical annunciation is in progress.
See Section 10 for more details.
• Immune to RFI/EMI disturbances.
• Available for explosion-proof and safe applications (CSA, FM). For
I.S. installations a sepatate barrier is required. Refer to product
label and Flowserve drawing 198736

10 Requirements for Safety
Integrity
This section provides information and additional user responsibilities
in order to meet Safety Integrity Level 2 (SIL 2) per IEC 61508 Parts
1-3.
10.1 Fail Safe State
The fail safe state for the Logix 3200MD positioner:
• Fail Safe State 1: The spool valve is at less than 5% of full
stroke such that Output (Port) 1 is venting and Output (Port) 2
is open to supply pressure.
• Fail Safe State 2: The spool valve is at greater than 95% of full
stroke such that Output (Port) 1 is supply pressure and Output
(Port) 2 is open to venting.
• ! NOTE that these represent the fail safe state of the positioner.
The valve fail safe state may be different depending on spring
confi guration and tubing. Ensure the valve fail-safe state is
appropriate for your application.
10.2 Safety Function
The Logix 3200MD positioner moves to fail-safe state upon the following conditions:
• Loss of supply pressure (less than approximately 7 psi).
• Fail Safe State 1
• Removal of analog input power (less than 4.0 mA)
• Fail Safe State 1
10.3 Fail Safe State Response Time
A typical response time for the spool to move to a fail safe state
due to a complete and sudden loss of supply pressure or a sudden
command change is less than 50 ms*. The response time may be
slower, possibly up to 1 second with subzero (F) temperatures.
A typical response time for the spool to move to a fail safe state due
to linkage pin failure is less than 200 ms*. The response time may
be slower with stroke lengths longer than 8 inches.
A typical response time for a valve to move to a fail safe state due
to a complete and sudden loss of supply pressure or a sudden
command change can be less than 150 ms*. However, the response
time will vary widely with actuator size, stroke length, starting position, fail safe direction, tubing size, supply pressure, and temperature. The positioner air fl ow capacity affects the speed of the valve
moving to a fail-safe position. See section 4.1 for air fl ow capacity.
Test the fi nal valve assembly response time to ensure it meets your
requirements.
*Tests were with a 25 inch double acting actuator, ambient temperature 74°F (23.3 °C), 60 PSI (4.1 bar) supply, quarter inch tubing,
starting at 50% open, moving to close, .75 inch stroke, 1.5 inch
feedback arm.
10.4 Diagnostic Annunciation and
Response Time
The Flowserve 3200MD Positioner will report the conditions below
within 1.0 second of occurrence by transition of the Analog Output
to less than or equal to 3.6 mA for as long as the condition exists.
• Analog input less than approximately 2.0 mA.
• Disconnection of feedback arm mechanism.
• Fail Safe State 1 or 2 (confi guration dependent).
The Logix 3200MD positioner detects and annunciates the following
safety related conditions:
• Analog input less than approximately 2.0 mA.
• Analog output power less than approximately 12.5 V.
• Pilot Relay Response Alarm (user adjustable settings)
• Position Deviation Alarm (user adjustable settings)
• Pilot Relay Position Limit Alarm
For a detailed description of these alarms, See section 7.10 Logix
3200MD Status Conditions.
30
• Analog output power less than approximately 12.5 V.
• Detection of one of the following safety related alarms.
• Pilot Relay Response Alarm (user adjustable settings)
• Position Deviation Alarm (user adjustable settings)
• Pilot Relay Position Limit Alarm
Upon detection of the alarms, the Analog Output will remain at less
than or equal to 3.6 mA for at least 5 seconds or as long as the
alarm persists.
Should any of the safety related alarms arise, the positioner will
continue to attempt to control to the analog input signal.
The settings of the Pilot Relay Response Alarm and the Position
Deviation Alarm affect the time between the occurrence of a physical
problem and the generation of the alarm. Ensure these settings are
adjusted to an acceptable level. The Pilot Relay Position Limit Alarm
can take up to 8 seconds to generate if the spool sticks suddenly.
User Instructions - Digital Positioner 3200MD LGENIM0059-09 12/13
10.5 Maximum Achievable SIL
The Flowserve 3200MD Valve Positioner covered by this safety
manual is suitable for use in low demand mode of operation Safety
Integrity Functions (SIF) up to SIL 2 in simplex (1oo1) confi gurations. The achieved SIL for a particular SIF needs to be verifi ed by
PFDavg calculation for the entire SIF including the failure rates of the
associated sensors and valves that are also part of the SIF.
Use of the Flowserve 3200MD Valve Positioner in a redundant
(1ooN) confi gurations is also limited to SIL 2.
For details, contact your Flowserve representative for Failure Mode,
Effects, and Diagnostics Analysis (FMEDA) report number FLO 0911-42 R001 for Logix 3200MD.
10.6 Model Selection and Specifi cation of
Flowserve 3200MD Positioner
In order to be used for SIL 2 applications as stated above, the Logix
3200MD positioner must have software version 2.05 or greater and
an Analog Output board.
The model number can be viewed on the metal tag on the positioner.
You may have a 3200IQ model that was upgraded to a 3200MD in
which case, stickers on the cover will denote the upgrade has taken
place. The software version may be verifi ed by following the instructions in section 7.9. The presence of an Analog Output board can be
verifi ed by removing the covers and viewing the circuit board. See
fi gure 24.
10.9 Required Confi guration Settings
The following user settable options must be properly confi gured
for the individual application in order to provide the designed safety
integrity for that application. A method of HART communication is
required such as a HART 375 Handheld Communicator or confi guration software such as ValveSight.
• Calibrate the A/O board.
• Software version 2.08 or later requires the following confi guration: Enable the AO safety annunciation using the ValveSight
DTM or a Hand-held device. If using the DTM, locate the “Edit
Variables”feature. Change variable 240 to a value of 1. If using
a Hand-held device, navigate to the Confi guration menu. Use
the Write Register function to change variable 240 to a value of
1. The register type is “char”.
• Calibrate the analog input (command). The fail safe state must
correspond to the analog input command at low current. (e.g.
For fail safe state = closed, low command (at least 4 mA)
must correspond with fully closed. For fail-safe state of open,
the low command (at least 4 mA) must correspond with fully
opened.)
• Set the MPC to be active when the positioner is given an analog
input command to move to the fail safe state. Guarantee tight
shut-off by allowing some degree of margin taking into account
command input tolerances. (For example, if the input command
tolerance is +\- 0.5%, set the MPC to 2% when the fail safe
state is closed.)
10.7 Installation
Ensure installation is properly performed according to this manual.
Ensure tubing is confi gured to the actuator so that the fail-safe state
of the positioner matches the desired fail-safe state of the valve.
Ensure the feedback spring is confi gured for the appropriate fail-safe
direction for the valve. For SIL 2 applications, the positioner may be
ordered with the feedback spring reversed. See Fail Option Feedback
in the How To Order section.
Ensure the A/O board has been installed. If no A/O board has been
installed, follow installation instructions in section 9.3.
market installation of the A/O board will void FM and CSA certifi cations in North America.
! NOTE: After
10.8 Firmware Update
Ensure the fi rmware version is 2.05 or greater. The software version
may be verifi ed by following the instructions in section 7.9. Only
authorized representatives of Flowserve may update fi rmware. If
fi rmware update is required, contact your sales representative. See
the back cover of this manual for contact information.
• Set the MPC such that during normal operation MPC is not active. When MPC is active, some diagnostics are disabled.
• Adjust the Pilot Relay Response Alarm settings as desired.
• Adjust the Position Deviation Alarm settings as desired.
• It is recommended to lock the local interface to prevent unintended adjustments of the settings by an unauthorized user.
10.10 Reliability Data
For reliability data, a detailed Failure Mode, Effects, and Diagnostics
Analysis (FMEDA) report has been prepared and is available from
Flowserve with all failure rates and failure modes for use in SIL
verifi cation. See FMEDA report number FLO 09-11-42 R001 for
Logix 3200MD.
! NOTE that the failure rates of the associated sensors and actua-
tors need to be accounted for in the Safety Instrumented Function
(SIF) level Probability of Failure High on Demand PFDavg calculation.
31
User Instructions - Digital Positioner 3200MD LGENIM0059-09 12/13
10.11 Lifetime Limits
The expected lifetime of the Flowserve 3200MD Positioner is approximately 10 years. The reliability data listed the FMEDA report is
only valid for this period. The failure rates of the Flowserve 3200MD
Valve Positioner may increase sometime after this period. Reliability calculations based on the data listed in the FMEDA report for
lifetimes beyond 10 years may yield results that are too optimistic,
i.e. the calculated Safety Integrity Level may not be achieved.
10.12 Proof Testing
The objective of proof testing when used in low demand mode
of operation is to detect failures within Flowserve 3200MD Valve
Positioner and its associated sensors and actuators that may not be
detected by the normal self diagnostics. Of main concern are undetected failures that prevent the safety instrumented function from
performing its intended function.
The frequency of the proof tests (or the proof test interval) is to be
determined in the reliability calculations for the safety instrumented
functions for which the Flowserve 3200MD Valve Positioner is applied. The actual proof tests must be performed at least as frequently
as specifi ed in the calculation in order to maintain required safety
integrity of the safety instrumented function.
When the tests listed above are executed a proof test coverage of
95% can be claimed.
10.13 Maintenance
Calibrations should be checked annually.
10.14 Repair and Replacement
In the unlikely event that the Flowserve 3200MD Valve Positioner
fails, the failure should be reported to Flowserve. Replace faulty
components according to section 8 of this manual or return the
positioner to Flowserve for service.
10.15 Training Requirements
Activities specifi ed in this manual shall be performed by a service
technician trained in the installation and maintenance of process
instrumentation.
The following tests need to be specifi cally executed when a proof
test is performed. The results of the proof test need to be documented and this documentation should be part of a plant safety
management system. Positioner failures that are detected should be
reported to Flowserve.
To perform the proof testing, a HART communicator such as a 375
Handheld or software such as ValveSight DTM for Logix 3200MD
are required.
Steps for Proof Test
Step Action
1. Bypass the safety PLC or take other appropriate action to avoid
a false trip.
2. Set the analog input command to less than 2.0 mA.
3. Ensure that the attached valve is fully in the safe state (defi ned
by application) and has moved to that position within the
allowed time. This tests for all failures that could prevent the
closure of the valve, including electronic and mechanical faults,
as well as valve faults.
4. Inspect the 3200MD Valve Positioner for any visible damage
or contamination and ensure the follower arm has suffi cient
spring bias.
5. Remove the bypass from the safety PLC or otherwise restore
normal operation

14 Frequently Asked Questions
Q: My DCS uses 24 VDC, can I run a Logix 3200MD?
A: A DCS output current card does run from 24 VDC but the card regulates
the actual current output. However, if the 24 VDC were applied directly across
the terminals, nothing would limit the current and the Logix 3200MD Field
Termination Board could be damaged. The current source voltage supply can
be anywhere between 10 VDC to 30 VDC as long as the current is limited in the
4-20 mA range.
Q: I accidentally placed a voltage supply across the Logix 3200MD. How do
I know if I damaged something?
A: The typical failure in an over-current situation is a short circuit. Your loop
current will be maintained but the Logix 3200MD control board will receive
no power. With power removed from the Logix 3200MD, use an ohmmeter to
measure across the terminals. If the reading is a short (close to zero ohms),
the Customer Interface Board must be replaced. Make sure the positive lead is
on the ‘+’ terminal and negative lead is on the ‘-’ terminal when measuring the
resistance.
Q: What is the input resistance of the Logix 3200MD?
A: The Logix 3200MD does not have a simple resistive input. When measuring
the voltage across the Logix 3200MD, it only varies slightly when the current
is changed from 4 mA to 20 mA (9.8 to 10.0 VDC nominal without HART communications. Add 0.3 V with HART active). This is because the Logix 3200MD
is an active device. The resistance at a given current is commonly referred to
as the effective resistance.
Effective Resistance = (Terminal Voltage)/Current
For example:
at 20 mA: Effective resistance = 9.9 VDC/0.02 A = 495 Ω
The Logix 3200MD has a specifi cation of 495 Ω @ 20 mA.
! NOTE: Your cannot measure across the terminals of an unpowered Logix
3200 and get the effective resistance.
Q: How do I know if I need a VHF HART fi lter?
A: If the current source is interfering with communication, it will affect both
ValveSight and the HART 375 handheld. If the positioner communicates to
ValveSight or the HART 375 handheld when using a current source (a 4-20 mA
current calibrator, for example) and not the DCS, it indicates a fi lter is necessary with that current source. Some 4-20 mA calibrators that work without a
fi lter are listed below. If one of these is available, try to connect with ValveSight
or the HART 375 handheld again. If communications are established while using one of these sources but fails on the original source, a fi lter is needed.
Handheld 4-20 mA calibrators which do not require a fi lter:
• Altek Model 334
• Rochester Instrument Systems (RIS) CL-4002
• Unomat UPS-II
Q: I set the MPC at 5 percent. How will the positioner operate?
A: Assume that the present command signal is at 50 percent. If the command
signal is decreased, the positioner will follow the command until it reaches
Equation 3
5 percent. At 5 percent, the spool will be driven fully open or fully closed,
depending on the air action of the valve, in order to provide full actuator
saturation and tight shutoff. The positioner will maintain full saturation below
5 percent command signal. As the command increases, the positioner will
remain saturated until the command reaches 6 percent (there is a 1 percent
hysteresis value added by the positioner). At this point, the stem position will
follow the command signal. While in MPC, the Logix 3200MD LEDs will blink
GGGY.
Q: I have MPC set to 3 percent but the valve will not go below 10 percent.
A: Is a lower soft stop enabled? The lower soft stop must be less than the
lower PMC setpoint in order for the lower MPC to become active. When the
lower soft stop is reached, the positioner will blink a GYGY code. When MPC
is active, the positioner will blink GGGY.
Q: Will soft stops prevent the valve from going to its fail position?
A: No.
Q: What is the difference between models with Standard (3200MD),
Advanced (3210MD) and Pro (3220MD) diagnostics?
A: All models use the pressure sensors in the positioner control algorithm
to enhance valve stability. The model with Advanced diagnostics performs
calculations such as detection of loss of pressure, diagnostic signatures and
data logging. The model with Pro diagnostics adds full diagnostic capabilities including continuous on-line friction, pneumatic leak and actuation ratio
analysis. Pro diagnostics support comprehensive health views in the ValveSight DTM. Partial stroke tests and long term trends of many key parameters
are also available with Pro diagnostics.
Q: Can I upgrade from a Standard to Advanced or from Advanced to Pro
diagnostics?
A: Yes. Upgrading can be accomplished using ValveSight DTM software.
After upgrading, pressure and friction calibrations can be performed using
the ValveSight DTM or the HART 375 handheld.
Q: Can I add pressure sensors to my 3200IQ and upgrade it to a 3220MD
with Pro diagnostics?
A: This depends on the certifying agency. Some agencies do not allow fi eld
upgrades which change the physical confi guration. If the certifying agency
allows physical upgrades, the pressure sensor board assembly can be purchased and installed. A Flowserve technician can update the positioner software from IQ to the desired MD version (Advanced or Pro). If the certifying
agency does not allow physical upgrades, a Flowserve technician can update
the positioner software from the IQ to the desired MD version (Advanced or
Pro). If the certifying agency does not allow physical upgrades, a Flowserve
technician can update the positioner software to turn the 3200IQ into a
3200MD (with Standard diagnostics) allowing it to work with the ValveSight
DTM. See the Logix 3200IQ IOM for instruction on removing the plug plate
and installing the pressure sensors. For any questions regarding this upgrade
or the certifying agencies’ rules, contact the Flowserve Springville Quality
Department.
Q: Does the QUICK-CAL perform all the required calibrations for an Advanced or Pro Diagnostics level Logix positioner?
A: No, the advanced diagnostics feature of the ValveSight technology requires
the user to input the size of the actuator and the supply pressure into the
positioner. This cannot be done with a QUICK-CAL only. Perform a Stroke,
Actuator and Friction calibration through the ValveSight DTM or HART
handheld.
