Figure 1: Logix 3200IQ Digital Positioner

Positioner Overview

The Logix 3200IQ digital positioner is a two-wire
4-20 mA input digital valve positioner. The positioner is
configurable through the local user interface. The Logix
3200IQ utilizes the HART protocol to allow two-way
remote communications with the positioner. The Logix
3200IQ positioner can control both double- and single­acting 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.

Automax Logix 3200IQ Digital Positioner

Installation, Operation and Maintenance Instructions

Positioner Operation

The Logix 3200IQ positioner is an electric feedback
instrument. Figure 2 shows a Logix 3200IQ positioner
installed on a double-acting actuator.

The Logix 3200IQ 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
selection can be accessed with SoftTools software, the
HART 275/375 communicator, or other host software.

The input signal in percent passes through a
characterization/limits modifier 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-field
customer adjustment. The positioner has three basic
modes: Linear, Equal Percent (=%) and Custom
characterization. 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-defined 21-point output curve. The custom

Automax Logix 3200IQ Digital Positioner

Installation, Operation and Maintenance Instructions

user-defined 21-point output curve is defined using a
handheld or PC software. In addition, two user-defined
features, Soft Limits and MPC (Minimum Position Cutoff),
may affect the final 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 3200IQ uses a two-stage, stem-positioning
algorithm. The two stages consist of an inner-loop,
spool control and an outer-loop, 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 deflects
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.

Detailed Sequence of Positioner Operations

A more detailed example explains the control function.
Assume the unit is configured 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% command.

• Actuator is tubed and positioner is configured
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 3, 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.

Installation, Operation and Maintenance Instructions

5. Making sure positioner shaft rotation matches actuator
shaft rotation, place positioner on mounting bracket
(Figure 7). Make sure shafts engage. Do not insert

fasteners into positioner at this time.

Figure 7: Positioner on Mounting Bracket

6. Double-check actuator and positioner rotation. Hold
positioner against bracket with fingertips as shown in
Figure 8.

Figure 8: Check Positioner Shaft Alignment

WARNING: Keep away from positioner sides, as
positioner will suddenly rotate on bracket if not
properly aligned and cause injury.

Slowly rotate the actuator. If the positioner shaft is
properly aligned, the shaft will rotate freely. If not, the
mechanical stops will grab, causing the positioner body
to rotate on bracket.

7. If the shaft is not properly aligned, repeat steps 3-6.
Otherwise, attach positioner to bracket with fasteners
included with bracket. Tighten bolts finger-tight only at
this time.

8. Stroke actuator/positioner several times to align shafts.
Tighten all fasteners.

Tubing Positioner to Actuator

Proper tubing orientation is critical for the positioner to
function correctly and have the proper failure mode. Referring
to Figure 2, note that for air-to-open valves, the Output 1 port
of the positioner manifold is tubed to the ‘open’ side of the
actuator. The Output 2 port of the positioner manifold is tubed
to the ‘closed’ side of the actuator. For air-to-close valves the
above configuration is reversed.

Wiring and Grounding Guidelines

(See Figure 9)

WARNING: This product has electrical conduit
connections in either thread sizes 1/2" 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
certifications. Conduit fittings must match
equipment housing threads before installation.
If threads do not match, obtain suitable adapters
or contact a Flowserve representative.

4-20 mA Command Input Wiring

Verify polarity when making field 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 9). Never
connect a voltage source directly across the Logix 3200IQ
terminals. The current must always be limited for 4-20
mA operation. Minimum operating current is 3.6 mA.

The input loop current signal to the Logix 3200IQ 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.

Automax Logix 3200IQ Digital Positioner

Installation, Operation and Maintenance Instructions

NOTE: The Logix 3200IQ positioner carries an
intrinsically safe barrier rating of 100 mA. Input
currents should not exceed 100 mA.

Figure 9: Field Termination

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.

Compliance Voltage (See Figure 10)

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 3200IQ
positioner impedance. The Logix 3200IQ 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 3200IQ 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.

WARNING: Never connect a voltage source directly
across the positioner terminals. This could cause
permanent circuit board damage.

Determine if the loop will support the Logix 3200IQ digital
positioner by performing the following calculation.

Equation 1

Voltage = Compliance Voltage (@Current

The calculated voltage must be greater than 10 VDC in
order to safely support the Logix 3200IQ digital
positioner.

Voltage = 19 VDC – 0.020 A • (300 Ω + 25 Ω) = 12.5 VDC

The voltage 12.5 VDC is greater than the required

10.0 VDC; therefore, this system will support the Logix

3200IQ digital positioner. The Logix 3200IQ positioner

has a worst case input resistance equivalent to 500 Ω

at a 20 mA input current.

Automax Logix 3200IQ Digital Positioner

Installation, Operation and Maintenance Instructions

Cable Requirements

The Logix 3200IQ 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.

In order to calculate the maximum network capacitance,
use the following formula:

Equation 2

To control cable resistance, 24 AWG cable should be used
for runs less than 5000 feet. For cable runs longer than
5000 feet, 20 AWG cable should be used.

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.

The Logix 3200IQ local user interface (Figure 11) allows
the user to configure the basic operation of the positioner,
tune the response and calibrate the positioner without
additional tools or configurators. The Local interface
consists of a QUICK-CAL button for automatic zero and

span setting, along with two jog buttons (↑ and ↓) for

spanning valve/actuators with no fixed internal stop in the
open position. There is also a DIP switch block containing
eight switches. Seven of the switches are for basic
configuration settings and one is for calibration options.
There is also a rotary selector switch for adjusting the
positioner gain settings. For indication of the operational
status or alarm conditions there are also three LEDs on
the local user interface.

Figure 11: Local User Interface

Initial DIP Switch Settings

Before placing the unit in service, set the DIP switches in
the Configuration and Cal boxes to the desired control
options. A detailed description of each DIP switch setting
follows.

NOTE: The Logix 3200IQ positioner reads the DIP
switch settings each time the QUICK-CAL button is
pressed. If a HART handheld or Flowserve PC software
is used to configure and then calibrate the positioner,
the DIP switches are not read. The auto-tune
adjustment switch labeled “GAIN” is always live and
can be adjusted at any time.

Installation, Operation and Maintenance Instructions

Description of Configuration DIP Switch Settings

The first seven DIP switches are for basic configuration.
The function of each switch is described below.

Air Action

This must be set to match the configuration of the
valve/actuator mechanical tubing connection and spring
location since these determine the air action of the
system.

ATO (air-to-open) – Selecting ATO if increasing output
pressure from the positioner is tubed so it will cause the
valve to open.

ATC (air-to-close) – Selecting ATC if increasing output
pressure from the positioner is tubed so it will cause the
valve to close.

Signal at Closed

Normally this will be set to 4 mA for an Air-to-open
actuator and 20 mA for an Air-to-close actuator
configuration.

4 mA – Selecting 4 mA will make the valve fully closed
when the signal is 4 mA and fully open when the signal
is 20 mA.

20 mA – Selecting 20 mA will make the valve fully
closed when the signal is 20 mA and fully open when
the signal is 4 mA.

Figure 12: Default Custom Characterization

Pos. Characterization

Linear – Select Linear if the actuator position should be
directly proportional to the input signal.

Optional – Select Optional 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 rangeability curve.

Custom – If Custom is selected, the positioner will be
characterized to a custom table that must be set-up
using a properly configured HART 275/375 handheld or
other host software. Custom characterization can be
thought of as a “soft CAM.” The user can define a
characterization curve using 21 points. The control will
linearly interpolate between points. Points do not have
to be equally spaced in order to allow more definition at
critical curve areas. The default values will linearize the
output of a valve with an inherent =% characteristic
(e.g., ball valves).

Automax Logix 3200IQ Digital Positioner

Installation, Operation and Maintenance Instructions

Auto Tune

This switch controls whether the positioner will auto tune
itself every time the QUICK-CAL button is pressed or use
preset tuning parameters.

On – On enables an auto tune feature that will
automatically determine the positioner gain settings
based on the current position of the adjustable 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 rotary switch position. (Note that there is a
small black arrow indicating the selection. The slot in
the switch is NOT the indicator.)

Figure 13: Adjustable GAIN Switch

If the adjustable GAIN selector switch is set to “E”
with the auto tune switch on, a Flowserve standard
response tuning set will be calculated and used based
on response parameters measured during the last
QUICK-CAL.

If the adjustable GAIN selector switch is set to “D”, “C”,
“B”, or “A” with the auto tune switch on, progressively
lower gain settings will be used based on response
parameters measured during the last QUICK-CAL.

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.

Off – Off forces the positioner to use one of the factory
preset tuning sets determined by the adjustable GAIN
selector switch. Settings “A” through “H” are progress­ively higher gain predefined tuning sets. The GAIN
selector switch is live and can be adjusted at any time
to modify the tuning parameters.

NOTE: “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.

Configuration Switches

Enabled – By selecting Enabled, the Logix 3200IQ
will read all of the configuration switches each time a
QUICK-CAL is performed to determine the configuration.

Disabled – Selecting Disabled retains the last
configuration in memory (from the last successful
calibration) before the switch was set to Disabled.
With this setting a QUICK-CAL only zeros and spans
the positioner.

Stability Switch

This switch adjusts the position control algorithm of
the positioner for use with low-friction control valves
or high-friction automated valves.

Low-Friction Valves – Placing the switch to the
left optimizes the response for low-friction, high­performance control valves. This setting provides
for optimum response times when used with most
low-friction control valves.

High-Friction 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.

Description of Cal DIP Switch Settings

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 self-calibration.
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
physical 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.

Automax Logix 3200IQ Digital Positioner

Installation, Operation and Maintenance Instructions

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 three seconds will
initiate the calibration. If the Config-Switches option is
enabled, the settings of all the configuration switches
are read and the operation of the positioner adjusted
accordingly. A QUICK-CAL can be aborted at any time by
briefly pressing the QUICK-CAL button and the previous
settings will be retained.

If the Quick Calibration switch (be careful not to confuse
this 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 flashing indicating the calibration progress.
When the lights return to a sequence that starts with a
green light the calibration is complete. An explanation of
the various light sequences follows. The initial calibration
of extremely large or 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 first successful calibration that one more
calibration be completed for optimum performance.

WARNING: When operating using QUICK-CAL or
local control, 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.

Manual Jog Calibration Operation

If the Quick Calibration switch is set to Jog, the calibration
will 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 configuration
software is required. When performing a jog calibration,
the LEDs will flash in a sequence of Y-R-R-G (yellow-red­red-green) which indicates that the user must use the

Jog buttons (↑ and ↓) to manually position the valve to

approximately 100%. When the valve is approximately

100% open press both the Jog buttons (↑ and ↓)

simultaneously to proceed to the next step. The valve will
stroke and then wait while flashing the Y-R-R-G sequence
again, allowing the user to adjust the valve position a
second time to exactly 100% using the Jog buttons

(↑ and ↓). When the stem is properly positioned press

both the Jog buttons (↑ and ↓) simultaneously again to

register the 100% position and proceed. No more user
actions are required while the calibration process is
completed. When the lights return to a sequence that
starts with a green light the calibration is complete.
An explanation of the various light sequences follows.

Local Control of Valve Position

Local control of valve position can be achieved from the
user interface by holding down both Jog buttons and the
QUICK-CAL button simultaneously for three seconds.
While in this mode the LEDs will flash a YGRR (yellow­green-red-red) sequence. Use the two Jog buttons

(↑ and ↓) to manually control the position of the valve.

To exit the local control mode and return to normal
operation, briefly press the QUICK-CAL button.

Factory Reset

To perform a factory reset, disconnect power, hold the
QUICK-CAL button down and reconnect power.
Performing a factory reset will cause all of the internal
variables, including calibration, to be reset to factory
defaults. The positioner must be recalibrated after a
factory reset. Tag names and other user configured limits,
alarm settings and valve information will also need to
be restored.

WARNING: Performing a factory reset may result in
the inability to operate the valve until reconfigured
properly. Notify proper personnel that the valve may
stroke and make sure the valve is properly isolated.

Command Source Reset

Performing a command source reset will reset the
command source to analog source if it has been
inadvertently left in digital mode. This is done while a
QUICK-CAL is in process by holding down both the Jog

buttons (↑ and ↓) while briefly pressing the QUICK-CAL

button. A new QUICK-CAL must be done after resetting.

Logix 3200IQ Status Condition

The blink codes used to convey the status of the Logix
3200IQ digital positioner are described in the table below.
In general, any sequence starting with a green light
flashing first is a normal operating mode and indicates
that there are no internal problems. Any sequence starting
with a yellow light flashing indicates that the unit is in a
special calibration or test mode, or that there was a
calibration problem. Any sequence starting with a red light
flashing indicates that there is an operational problem
with the unit.

Installation, Operation and Maintenance Instructions

Logix 3200IQ Status Condition Codes

Colors ID Indication and Resolution

G - - - Any sequence starting with a green light flashing first is a

normal operating mode and indicates that there are no
internal problems.

GGGG 1 Normal operation - Analog Command mode. No errors,

alerts, or warnings.

GGGY 2 Tight shutoff (MPC) active - The command is below the

user-set limit for tight shutoff feature. This is a normal
condition for a closed valve. The factory default setting is
1% command. To clear the condition use handheld or
Flowserve-supplied software to reset the tight shutoff if the
range is incorrect or adjust the command signal above the
specified MPC value.

GGYG 3 Digital command mode - The analog 4-20 mA input signal

is ignored in this mode and a handheld or Flowserve­supplied software is needed to change the position
command. (Note a command reset is provided to change
the command back to analog control mode from the local
interface if a PC or handheld configurator is not available.)

GGYR 4 Initializing - This sequence should only be visible for three

sequences when powering up the unit.

GGRG 5 Cycle limit exceeded (user-set) - The cycle limit set by the

user has been exceeded. To clear use handheld or
Flowserve-supplied software to reset.

GGRY 6 Travel limit exceeded (user-set) - The total accumulated

travel limit set by the user has been exceeded. To clear use
handheld or Flowserve-supplied software to reset.

GYYR 7 Lower soft stop reached (user-set) - The unit is being

commanded to exceed a user-defined lower position limit
and the internal software is holding the position at the limit.
The function is similar to a mechanical limit stop except it is
not active if the unit is un-powered. To clear the condition
use handheld or Flowserve-supplied software to reset the
limit if more travel is needed or adjust the command signal
back in the specified range.

GYRY 8 Upper soft stop reached (user-set) - The unit is being

commanded to exceed a user-defined upper position limit
and the internal software is holding the position at the limit.
The function is similar to a mechanical limit stop except it is
not active if the unit is un-powered. To clear the condition
use handheld or Flowserve-supplied software to reset the
limit if more travel is needed or adjust the command signal
back in the specified range.

GRYR 9 Lower position alert (user-set) - The position has reached

or is exceeding a user-defined lower position indicator
similar to a limit switch indicator. To clear the condition use
handheld or Flowserve-supplied software to reset the
indicator if more travel is needed or adjust the command
signal back in the specified range.

GRRY 10 Upper position alert (user-set) - The position has reached

or is exceeding a user-defined upper position indicator
similar to a limit switch indicator. To clear the condition use
handheld or Flowserve-supplied software to reset the
indicator if more travel is needed or adjust the command
signal back in the specified range.

Y - - - Any sequence starting with a yellow light indicates that the

unit is in a special calibration or test mode, or that there
was a calibration problem.

YGYG 11 Signature test in progress - This is a test initiated by

Flowserve-supplied software that can only be cancelled by
that software.

YYYG 12 Loop calibration in progress - Calibration sequence

controlled by a handheld or Flowserve-supplied software
that can only be cancelled by that software.

YRGG 13 Stroke calibration in progress - Calibration sequence

started either using the local QUICK-CAL button or by a
handheld or Flowserve-supplied software. It may be
cancelled by briefly pushing the QUICK-CAL button.

YGRR 14 Local jog control model - The unit has been placed in a

local override mode where the valve can only be stroked
using the two local jog buttons. It may be cancelled by
briefly pushing the QUICK-CAL button.

YYGR 15 Pressure calibration in progress - Calibration sequence

controlled by a handheld or Flowserve-supplied software
that can only be cancelled by that software.

YYYY 16 Local user interface disabled - PC software has been used

to disable the local interface. If local control is desired then
the local interface must be re-enabled from the remote
software. This code is only present for a short time when
the QUICK-CAL button is pressed.

YRRG 17 Waiting - Adjust to full open position setting from

User — only used during Jog calibration see explanation
on page 11, “QUICK-CAL,” for operation.

YRYG 18 Setting IL offset while calibrating - An automatic step in

the calibration process that is done with the valve at 50%
position. This must be completed for proper calibration.

YRYY 19 No feedback motion while calibrating - Indicates that there

was no motion of the actuator based on the current stroke
time configuration. Check linkages and air supply to make
sure the system is properly connected. If the time out
occurred because the actuator is very large then simply
retry the QUICK-CAL and the positioner will automatically
adjust for a larger actuator by doubling the time allowed for
movement. This error may be cleared by briefly pushing the
QUICK-CAL button, which will force the positioner to use
the parameters from the last good calibration.

YRYR 20 Feedback 0% out of range - Calibration error indicating that

the position sensor was out of range during the calibration
of the closed position. To correct the condition, adjust the
positioner mounting, linkage or feedback potentiometer to
move the position sensor back into range then restart the
calibration. This error may be cleared by briefly pushing the
QUICK-CAL button, which will force the positioner to use
the parameters from the last good calibration.

YRRY 21 Feedback 100% out of range - Calibration error indicating

that the position sensor was out of range during the
calibration of the open position. To correct the condition,
adjust the positioner mounting, linkage or feedback
potentiometer to move the position sensor back into range
then restart the calibration. This error may be cleared by
briefly pushing the QUICK-CAL button, which will force the
positioner to use the parameters from the last good
calibration.

YRRR 22 Feedback span too small - The range of motion of the

position feedback arm was too small for optimum
performance. Check for loose linkages and/or adjust the
feedback pin to a position closer to the follower arm pivot
to create a larger angle of rotation and recalibrate. Briefly
pushing the QUICK-CAL button acknowledges this condition
and the positioner will operate using the current short
stroke calibration if otherwise a good calibration.

YRGR 23 Feedback unstable while calibrating - Check for loose

linkages or loose positioner sensor. This error may be
cleared by briefly pushing the QUICK-CAL button, which will
force the positioner to use the parameters from the last
good calibration. This error may appear on some very small
actuators during the initial calibration. Redoing the
calibration may clear the problem.

Installation, Operation and Maintenance Instructions

R - - - Any sequence starting with a red light indicates that there is

an operational problem with the unit.

RGRR 24 Position deviation (user-set) - The position has exceeded

user-defined error band between command and position.

RGYY 25 Pressure reading out of range - The internal pressure

sensors are either saturated with a pressure over 150 psi or
the sensor has failed. Check supply pressure and if OK
check the pressure sensor board connections and replace
pressure sensor board if necessary.

RGYR 26 Loss of supply pressure - The positioner has determined

that the supply pressure is below 15 psi. Check the supply
pressure and if OK check the pressure sensor board
connections and replace pressure sensor board if
necessary. Minimum recommended supply pressure is
30 psi for proper operation.

RYYY 27 Pilot relay non-motion alert - Check to make sure the air

supply is connected. Also check the internal wiring
harnesses for good connections. This error may be cleared
by briefly pushing the QUICK-CAL button, which will force
the positioner to use the parameters from the last good
calibration. If the positioner still does not operate replace
the pneumatic relay assembly.

RYYR 28 Pilot relay lower position alert - Check to make sure the

air supply is connected. Also check the internal wiring
harnesses for good connections. This error may be cleared
by briefly pushing the QUICK-CAL button, which will force
the positioner to use the parameters from the last good
calibration. If the positioner still does not operate replace
the pneumatic relay assembly.

RYRY 29 Pilot relay upper position alert - Check to make sure the

air supply is connected. Also check the internal wiring
harnesses for good connections. This error may be cleared
by briefly pushing the QUICK-CAL button, which will force
the positioner to use the parameters from the last good
calibration. If the positioner still does not operate replace
the pneumatic relay assembly.

RRGG 30 Watchdog timer timeout (also listed as internal voltage

reference) - This is often caused when intermittent
operation occurs when connecting power. Remove power
and then reconnect to clear. If problem persists it is a bad
electronic assembly, replace.

RRYG 31 Internal temperature alert - The internal positioner

temperature is currently exceeding operational limits of

-40°F (-40°C) or 185°F (85°C).

RRYY 32 Piezo voltage error - Bad electronic assembly, replace.
RRYR 33 Internal voltage reference error - Indicates that the circuit

board is drawing too much power. Check internal wiring and
connectors for electrical shorts – if no shorts are present,
replace the electronic assembly.

RRRY 34 NV RAM checksum error - The checksum of the internal

data was not updated correctly. Cycle power and complete
a QUICK-CAL if error persists. Check internal data to verify
correct settings. If the error still occurs, replace the
electronic assembly.

Version Number Checking

The version number of the embedded code may be
checked at any time except during a calibration by holding

down the up arrow Jog button (↑). This will not alter the

operation of the unit other than to change the blink
sequence to three blinks indicating the major version

number. Holding the down arrow Jog 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:

Color

First Second Third

blink value blink value blink value

Green 0 0 0

Yellow 9 3 1

Red 18 6 2

For example if holding the up arrow Jog button (↑) gave a
G-G-R code, and holding the down arrow Jog button (↓)

gave a Y-Y-G code then the resulting version number
would be (0+0+2).(9+3+0) or version 2.12.

Maintenance and Repair

Driver Module Assembly

The driver module assembly moves the spool valve by
means of a differential pressure across its diaphragm. Air
is routed to the driver module from the regulator through
a flexible hose. A barbed fitting connects the flexible hose
to the driver module assembly. Wires from the driver
module assembly connect the hall effect sensor and the
piezo valve modulator to the main PCB assembly.

Driver Module Assembly Replacement

To replace the driver module assembly, refer to Figures
14-18 and 28 and proceed as outlined below. The
following tools are required:

• Flat plate or bar about 1⁄ 8" thick

• Phillips screwdriver

• 1/4" nutdriver

WARNING: Observe precautions for handling
electrostatically sensitive devices.

Figure 14: Driver Module Assembly

1. Make sure the valve is bypassed or in a safe condition.

2. Disconnect the power and air supply to the unit.

3. Remove the driver module cover (Figure 17), using a
flat bar or plate in the slot to turn the cover.

4. Remove the spool valve cover by removing the screw

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.

sensor board contains two pressure sensors that measure
the pressure on output ports 1 and 2. The main PCB
electronics automatically senses the presence of the
pressure sensor board. If present, the actuator pressure
sensors are used in the positioner control algorithm to
enhance valve stability. For optimal performance, the
actuator pressure sensors need to be calibrated. The
actuator pressure sensor calibration is performed using a
HART 275/375 Handheld Communicator or configuration
software such as SoftTools.

In the standard model, the pressure sensor board is

Installation, Operation and Maintenance Instructions

14. Install the main PCB into the housing. Insert the
retaining screw through the board into the threaded
boss and tighten evenly, using a Phillips screwdriver.
Do not overtighten.

15. Reinstall the five wire connections (six wire
connections if the unit is equipped with the 4-20 mA

17. Reinstall all covers.

Optional Hardware

Vented Design (See Figures 21 and 23)

A standard Logix 3200IQ 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 3200IQ
positioners: the main housing chamber and the spool
valve chamber (Figures 21 and 23). The main chamber
vent is located on the backside of the positioner (see
Figure 19). Vented-design Logix 3200IQ positioners are
supplied from the factory with a fitting installed in the
main chamber vent. Connect the necessary tubing/piping
to this fitting 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 flow rate is 0.5 std ft3/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 23) must also be
vented through the spool valve cover. Vented-design
Logix 3200IQ positioners are supplied from the factory
with a fitting installed in the spool valve cover (item
SKU 179477). Connect the necessary tubing/piping to
this fitting 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.

Figure 22: Main Housing Vent

Figure 23: Spool Cover Vent

HART VHF Filter

HART communication superimposes two frequencies,
1200 Hz and 2200 Hz, on the DC 4-20 mA current signal.
Some current sources (DCS or 4-20 mA calibrator) can
interfere with the HART signal. This may prevent
communication with SoftTools or the HART 275/375
handheld. Intermittent communication may also be the
result of a HART incompatible current source. In this
case, a filter is necessary between the current source and
Logix 3200 to allow HART communication.

Flowserve makes a filter (Part No. 139774) that must be
used on each 4-20 mA line if the current source interferes
with communication (see Figure 24). The filter does not
affect the DC current but prevents the source from
affecting the HART frequencies. The filter comes in a
DIN rail-mount package.

NOTE: This filter is not rated for use in hazardous
areas. It should be located between the current source
and the barrier in intrinsically safe applications.

Figure 24: HART VHF Filter

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 SoftTools 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 Logix 3200IQ Spare
Parts Kit Section for part numbers.)

When using a HART modem with SoftTools or when using
the HART 275/375 handheld, the leads can be connected
anywhere across the 4-20 mA current signal. The leads
are not polarity sensitive. When using a filter, the
connection must be made between the filter output and
the Logix 3200IQ (see Figure 25).

4-20 mA Analog Output Board

The Logix 3200IQ digital positioner can be supplied to
provide an analog feedback signal of the stem position.
This option can also be retrofitted in the field. The 4-20
mA analog output board is wired in series with a 12.5 to
40 VDC power supply (see Figure 26). This position
feedback option has the following features and
specifications:

• Does not interfere with positioner operation.

• Calibration of the analog output signal is performed
using a HART 275/375 Handheld Communicator or
configuration software such as SoftTools.

• Output follows actual position of valve, including all
failure modes of positioner except loss of power. An

output of ≤3.15 mA is transmitted with loss of power

to the positioner.

• Immune to RFI/EMI disturbances.

• Available for explosion-proof and safe applications
(CSA, FM).

Replacing the 4-20 mA Analog Output Board

To replace the 4-20 mA analog output board, refer to
Figures 14, 18 and 28 and proceed as outlined below.
The following tools are required:

• Phillips screwdriver

WARNING: Observe precautions for handling
electrostatically sensitive devices.

Installation, Operation and Maintenance Instructions

Frequently Asked Questions

Q: My DCS uses 24 VDC, can I run a Logix 3200IQ?

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 3200IQ
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 3200IQ. 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
3200IQ control board will receive no power. With power
removed from the Logix 3200IQ, 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 3200IQ?

A: The Logix 3200IQ does not have a simple resistive
input. When measuring the voltage across the Logix
3200IQ, 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 3200IQ is an active device.
The resistance at a given current is commonly referred
to as the effective resistance.

Equation 3:

Effective Resistance = (Terminal Voltage)/Current

For example:

at 20 mA: Effective resistance = 9.9 VDC/0.02 A = 495 Ω
The Logix 3200IQ has a specification of 495 Ω @ 20 mA.

NOTE: You 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 filter?

A: If the current source is interfering with communication,
it will affect both SoftTools and the HART 275/375
handheld. If the positioner communicates to SoftTools or
the HART 275/375 handheld when using a current source
(a 4-20 mA current calibrator, for example) and not the
DCS, it indicates a filter is necessary with that current
source. Some 4-20 mA calibrators that work without a
filter are listed below. If one of these is available, try to
connect with SoftTools or the HART 275/375 handheld
again. If communications are established while using

one of these sources but fails on the original source,
a filter is needed.

Handheld 4-20 mA calibrators which do not require
a filter:

• 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
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
3200IQ 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 or equal to zero percent in order for the MPC
to become active. If a positive lower soft stop is written,
this stop will take priority over the MPC feature. When the
lower soft stop is reached, the positioner will blink a
GYYR code.

Q: Will soft stops prevent the valve from going to its
fail position?

A: No.

Q: What is the difference between a model with
Standard diagnostics and a model with Advanced
diagnostics?

A: The model with Advanced diagnostics adds top and
bottom actuator pressure sensors. This allows for more
diagnostic calculations such as loss of pressure, friction,
advanced signatures, and troubleshooting. The pressure
sensors, if present, are also used in the positioner control
algorithm to enhance valve stability.

Q: Can I upgrade from a Standard to an Advanced?

A: Yes. Referencing the IOM, an advanced pressure
sensor board assembly can be purchased. Simply replace
the pressure sensor plug plate with the advanced pressure
sensor board. Using SoftTools or the HART 275/375
handheld, configure the positioner for Advanced
Diagnostics and perform an actuator pressure calibration.
