3 Unpacking and Storage

3.1 Unpacking

1. While unpacking the Logix 3400IQ 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

c

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 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 ﬂoor. The storage location must also be free from ﬂooding, dust, dirt, etc.

Long Term Storage of Logix 3000 series Positioners in Humid Locations

The Logix 3000 series positioners are designed to operate in humid environments when connected to a proper instrument air supply. There are some occasions when valves and positioners are stored at job sites or installed and commissioned and then left without instrument air for months. To make startup easier for units that are left without instrument air and insure that the positioners will be ready to operate, it is recommended that the vent assembly of the positioner be sealed preferably with a desiccant pouch sealed with the vent assembly.

ﬂowserve.com

Logix 3400IQ Digital Positioner FCD LGENIM3401-00 – 06/06

The vent assembly is located in the upper left side of the positioner. The gaps around the assembly as noted by the arrows should be sealed for long term storage.

Joints to be sealed

Vent assembly

A small desiccant package as shown can be included under the sealing tape to insure proper protection.

Desiccant packet

Logix 3400IQ Digital Positioner FCD LGENIM3401-00 – 06/06

All of the edges around the vend assembly should be sealed similar to the picture below.

Removeable sealing tape

The sealing tape and desiccant should be removed when instrument air is permanently applied to the positioner.

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.

2. Inspect the solenoid and positioner soft goods and replace as necessary.

4.2 Positioner Operation

The Logix 3400IQ positioner is an electric feedback instrument. Figure 1 shows a Logix 3400IQ positioner installed on a double-acting linear actuator for air-to-open action.

The Logix 3400IQ receives power from the two-wire, FF input signal. This positioner utilizes FF communications for the command signal. The command source can be accessed with the Rosemount 375 communicator or other host software.

0% is always deﬁned as the valve closed position and 100% is always deﬁned as the valve open position. During stroke calibration, the signals corresponding to 0% and 100% are deﬁned.

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 four basic modes:

Linear, Equal Percent (=%), Quick Open (QO) 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. In Quick Open the input signal is mapped to an industry standard quick-open curve. If Custom char-

acterization is enabled, the input signal is mapped to either a default =% output curve or a custom, user-deﬁned 21-point output curve. The custom user-deﬁned 21-point output curve is deﬁned using a handheld or the Host conﬁguration tool software. In addition, two user-deﬁned features,

Soft

Limits and Final Value 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 3400IQ 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 compared against the 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 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.

uses a two-stage, stem-positioning algorithm. The two stages consist of an

Control Command is

Stem Position. If any deviation exists, the control algorithm sends a signal to

Control Command and Stem Position.

4.3 Detailed Sequence of Positioner Operations

A more detailed example explains the control function. Assume the unit is conﬁgured as follows:

• Unit is in

• Custom characterization is disabled (therefore characterization is Linear).

• No soft limits enabled. No Final Value Cutoff set.

• Valve has zero deviation with a present input command of 50.

• Write to Final_Value to change command.

• Actuator is tubed and positioner is conﬁgured air-to-open.

Given these conditions, 50 represents a is disabled so the 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

OOS.

Command source of 50 percent. Custom characterization

Command source is passed 1:1 to the Control Command. Since zero deviation

null or balanced spool position.

Assume the input signal changes from 50 to 75. The positioner sees this as a of 75 percent. With is the difference between 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

Linear characterization, the Control Command becomes 75 percent. Deviation

Control Command and Stem Position: Deviation = 75% - 50% = +25%,

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.

5 Mounting and Installation

5.1 Mounting to Valtek Linear Mark One Valves

To mount a Logix 3400IQ positioner to a Valtek linear Mark One valve, refer to Figure 3 and proceed as outlined below. The following tools are required:

• 9⁄16" open-end wrench (or ½" for spud sizes 2.88 and smaller)

• 7⁄16" box wrench

• 3⁄8" open-end wrench

1. Remove washer and nut from follower pin assembly. Insert pin into the appropriate hole in

follower arm, based on stroke length. The stroke lengths are stamped next to their corre sponding holes in the follower arms. Make sure the unthreaded end of the pin is on the stamped side of the arm. Reinstall lock washer and tighten nut to complete follower arm assembly.

2. Slide the double-D slot in the follower arm assembly over the ﬂats on the position feedback shaft

in the back of the positioner. Make sure the arm is pointing toward the customer interface side of the positioner. Slide lock washer over the threads on the shaft and tighten down the nut.

3. Align the bracket with the three outer mounting holes on the positioner. Fasten with ¼" bolts.

4. Screw one mounting bolt into the hole on the yoke mounting pad nearest the cylinder. Stop

when the bolt is approximately

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 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 YRYR or YRRY 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)

Figure 4: Standard Rotary Mounting

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

• 3⁄8" socket with extension

• 3⁄16" nutdriver

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.

ﬂowserve.com

Logix 3400IQ Digital Positioner FCD LGENIM3401-00 – 06/06

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

⁄16-18 x ½" bolts, attach bracket to actuator transfer case pad.

Leave these bolts slightly loose until ﬁnal 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. The pin should extend approximately

⁄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 3400IQ

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 RE-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 RE-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 YRYR or YRRY 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.

5.3 Optional Valtek Rotary Mounting Procedure (See Figure 5)

Figure 5: Optional Rotary Mounting

The optional rotary mounting applies to Valtek valve/actuator assemblies that are equipped with mounted volume tanks or handwheels. The optional mounting uses a four-bar linkage coupled to the valve shaft. The following tools are required:

• 3⁄8" open-end wrench

• 7⁄16" open-end wrench

• ½" open-end wrench

1. Using a ½" open-end wrench and two 5⁄16-18 x ½" bolts, attach bracket to actuator transfer case

pads. Leave bracket loose to allow for adjustment.

ﬂowserve.com

Logix 3400IQ Digital Positioner FCD LGENIM3401-00 – 06/06

2. Using four ¼-20 x ½" bolts and a 7⁄16" open-end wrench, fasten positioner to universal bracket,

using the four-hole pattern that locates the positioner the farthest from the valve. Rotate positioner 90 degrees from normal so gauges are facing upward.

3. Attach follower arm to positioner feedback shaft, using the star washer and 10-32 nut.

4. Attach tripper and tripper clamp to valve shaft using two ¼-20 bolts and two ¼-20 locknuts.

Leave tripper loose on shaft until ﬁnal adjustment.

5. Thread ball joint linkage end to tripper and tighten (thread locking compound such as Loctite

is recommended to prevent back threading). Adjust the length of tie rod so follower arm and tripper rotate parallel to each other (the rod must be cut to the desired length). Connect the other ball joint end to follower arm using a star washer and a 10-32 nut.

6. Tighten bracket and tripper bolting.

7. Check for proper operation, note direction of rotation.

WARNING: If rotating in wrong direction, serious damage will occur to the positioner

c

and/or linkage. Check air action and stroke direction carefully before initiating operation.

5.4 NAMUR Mounting Option

Logix 3200IQ is available with a NAMUR output shaft and mounts on an actuator using the ISO F05 holes. Proper alignment of the positioner shaft to the actuator shaft is very important since improper alignment can cause excess wear and friction to the positioner.

5.5 Tubing Positioner to Actuator

The Logix 3400IQ 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 3400IQ 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 ﬁlter 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 ﬁve 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 conﬁguration, that selection tells the control which way the actuator has

been tubed. The top output port is called 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 1 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 conﬁguration 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 orienta tion 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.

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.

6.1 FF Command Input Wiring

The Logix 3400IQ is non-polarity sensitive. Wire FF source to the input terminals (see Figure 6). Minimum operating voltage is 9 VDC.

The FF signal to the Logix 3400IQ 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. Refer to guidelines in FF AG-181 for proper wiring methods.

NOTE: The Logix 3400IQ positioner carries an intrinsically safe barrier rating of 250 mA. Input currents should not exceed 250 mA, 5 watts.

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.

6.3 Segment Compliance Voltage (See Figure 7)

Output compliance voltage refers to the voltage limit that can be provided by the FF source. A FF system consists of the FF source, wiring resistance, barrier resistance (if present), and the Logix 3400IQ positioner voltage. The Logix 3400IQ digital positioner requires that the system allows for a

9.0 VDC drop across the positioner at minimum segment voltage. The actual voltage at the terminals varies from 9.0 to 32.0 VDC depending on the FF signal and ambient temperature.

Determine if the segment will support the Logix 3400IQ

digital positioner by performing the following

calculation.

6.4 Cable Requirements

The Logix 3400IQ digital positioner utilizes the FF protocol. This communication signal is superimposed on the supply voltage.

FF rated cable should be used. Refer to H1 wiring speciﬁcation.

6.5 Intrinsically Safe Barriers

When selecting an intrinsically safe barrier, make sure the barrier is FF compatible. Although the barrier will pass the segment voltage and allow normal positioner operation, if not compatible, it may prevent FF communication.

The Logix 3400IQ local user interface (Figure 8) allows the user to conﬁgure the basic operation of the positioner, tune the response, and calibrate the positioner without additional tools or conﬁgura tors. The local interface consists of a RE-CAL button for automatic zero and span setting, along with two jog buttons ( position. There is also a DIP switch block containing eight switches. Six of the switches are for basic conﬁguration settings and two are for FF 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 three LEDs on the local user interface.

7.2 Initial DIP Switch Settings

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

NOTE: The Logix 3400IQ positioner reads the DIP switch settings each time the RE-CAL button is pressed. If a FF handheld or Host 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.

Transducer block settings will always override the DIP switch settings until the RE-CAL button is pressed.

7.3 Description of Conﬁguration DIP Switch Settings

The ﬁrst six 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.

GAIN

Auto Tune

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

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 RE-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 10: 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 RE-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 RE-CAL.

If the adjustable GAIN selector switch is set to “F”, “G”, or “H” with the auto tune switch on, progres

sively higher gain settings will be calculated and used based on response parameters measured during the last RE-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.

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.

ﬂowserve.com

Logix 3400IQ Digital Positioner FCD LGENIM3401-00 – 06/06

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.

proper personnel that the valve will stroke, and make sure the valve is properly isolated.

7.5 RE-CAL Operation

NOTE: The unit must be in OOS mode before a calibration sequence can begin.

The RE-CAL button is used to locally initiate a calibration of the positioner. Pressing and holding the RE-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 RE-CAL can be aborted at any time by brieﬂy pressing the RE-CAL button and the previous settings will be retained.

If the Quick Calibration switch (be careful not to confuse this with the RE-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 calibra tion 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 calibra

tion be completed for optimum performance.

Logix 3400IQ Digital Positioner FCD LGENIM3401-00 – 06/06

WARNING: When operating using RE-CAL or local control, the valve will not respond to

c

external commands. Notify proper personnel that the valve will not respond to remote command changes, and make sure the valve is properly isolated.

7.6 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-red-red-green) which indicates that the user must use the Jog buttons ( stem is properly positioned press both the Jog buttons ( 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.

7.8 Factory Reset

To perform a factory reset, disconnect power, hold the RE-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. 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

7.9 Logix 3400IQ Status Condition

The blink codes used to convey the status of the Logix 3400IQ 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 calibra

7.13 Calibration

7.13.1 CALIBRATE_FLAGS

Position 0% Calibration Flag in CALIBRATE_FLAGS

During stroke calibration, the Logix 3400 digital positioner checks to see if the linkage is placing the stem position sensor in range. If the valve stroke causes stem position measurement to go out of range in the closed position, a Position 0% Flag will be generated. The valve stem will stop in the closed position and the red LED will blink. Linkage must be adjusted to bring the sensor in range. Special LED indication: If the linkage is out of range, the LEDs can be used as an adjustment guide. The LED will change from a red to yellow when the linkage is brought into range.

Position 100% Calibration Flag in CALIBRATE_FLAGS

During stroke calibration, the Logix 3400IQ digital positioner checks to see if the linkage is placing the stem position sensor in range. If the valve stroke causes stem position measurement to go out of range in the open position, a Position 100% Flag will be generated. The valve stem will stop in the open position and the red LED will blink. Linkage must be adjusted to bring the sensor in range. Special LED indication: If the linkage is out of range, the LEDs can be used as an adjustment guide. The LED will change from a red to yellow when the linkage is brought into range.

Logix 3400IQ Digital Positioner FCD LGENIM3401-00 – 06/06

Position Span Flag in CALIBRATE_FLAGS

Position span is a check during stroke calibration to verify that the valve stem moved. The algorithm waits to see if no movement is detected when the valve is automatically stroked open. Anything that could prevent the valve from stroking will generate a Position Span error (no supply pressure, malfunctioning spool valve).

7.13.2 Control and Tuning

Setting P + I Parameters

Using the Host conﬁgurator, you can set individual tuning parameters. A few key points are mentioned below. (See Figure 11

GAIN_UPPER, GAIN_LOWER, and GAIN_MULT: These three parameters are related by the following formula.

Proportional Gain =

Maximum Gain - | deviation | x Gain Multiplier

If Proportional Gain < Minimum Gain, then Proportional Gain = Minimum Gain

This algorithm allows for quicker response to smaller steps yet stable control for large steps. Setting the gain multiplier to zero and max gain = min gain results in a typical ﬁxed proportional gain.

The higher the gain multiplier, the larger the required deviation before the gain increases. Default values upon initiating a RESET to factory defaults (under LOAD_EE_DEFAULTS) are maximum gain =

2.0, minimum gain= 1.0, and gain multiplier= 0.05. These values will allow stable control on all Valtek control product actuator sizes.

Integral Gain (IGAIN): The integral gain is primarily for deviations due to temperature drift within the inner loop spool control. The factory default value is 10. Although higher numbers can speed the time it takes to reach zero deviation, it can add overshoot if too large. It is recommended that maximum and minimum gains be adjusted while leaving integral gain ﬁxed at 10. Integration is disabled below a stem position of 3 percent and above a stem position of 97 percent. This is to prevent integration windup from calibration shifts due to lower pressure or a damaged seat that may prevent fully closing the valve.

Integration Summer: The integral summer within the Logix 3400IQ digital positioner is clamped at +20 percent and -20 percent. If the integration summer is ﬁxed at +20 percent or -20 percent, it usually indicates a control problem. Some reasons for a clamped integration summer are listed below:

• Stroke calibration incorrect.

• Any failure which prevents stem position movement: stuck spool, handwheel override, low

pressure.

• Incorrect inner loop offset.

• Loss of air supply on a fail in place actuator.

Logix 3400IQ Digital Positioner FCD LGENIM3401-00 – 06/06

Writing a zero to integral gain (IGAIN) will clear the integral summer. The integral gain can then be returned to its original value.

Inner loop offset (IL_OFFSET): Three control numbers are summed to drive the inner loop spool position control: proportional gain, integral summer, and inner-loop offset.

Inner-loop offset is the parameter that holds the spool in the ‘null’ or ‘balance’ position with a control deviation of zero. This value is written by the positioner during stroke calibration and is a function of the mechanical and electrical spool sensing tolerances. However, if it becomes necessary to replace the driver module assembly or the software RESET calibration constants has been performed, it may be necessary to adjust this value. The method below should be used to adjust inner-loop offset.

Or simply perform a new stroke calibration.

From the ﬁeldbus conﬁgurator:

• Set transducer block to OOS

• Enable Diagnostic Variable access in TEST_MODE

• Send a 50 percent command.

• Set integral to zero.

• Locate the DAC_PERCENT

• Write this percentage value to IL_OFFSET

• Write original value to Integral

These tuning sets can be used to obtain initial values for Flowserve products and comparable actuator sizes. The user may need to adjust this tuning to achieve optimal performance for a particular application.

7.14 Alerts

7.14.1 FINAL_VALUE_CUTOFF

The FINAL_VALUE_CUTOFF or tight shutoff feature of the Logix 3400IQ digital positioner allows the user to control the level at which the command signal causes full actuator saturation in the closed or open position.

This feature can be used to guarantee actuator saturation in the closed or open position or prevent throttling around the seat at small command signal levels. To enable, use conﬁguration to apply the desired FINAL_VALUE_CUTOFF threshold.

NOTE: The positioner automatically adds a 1 percent hysteresis value to the FINAL_VALUE_CUTOFF_ LO setting to prevent jumping in and out of saturation when the command is close to the setting.

7.14.2 Effects of FINAL_VALUE_CUTOFF on Operation

With the FINAL_VALUE_CUTOFF_LO set at 5 percent the positioner will operate as follows: 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, full actuator saturation will occur. The actuator will maintain full saturation below 5 percent command signal. Now, as the command increases, the positioner will remain saturated until the command reaches 6 percent (remember the 1 percent hysteresis value added by the positioner). At this point, the stem position will follow the command signal.

If the FINAL_VALUE_CUTOFF_LO is set to 3 percent but the valve will not go below 10 percent, SOFTSTOP_LOW may be enabled. The lower soft limit must be less than or equal to 0 percent in order for the FINAL_VALUE_CUTOFF_LO to become active.

If soft stops are active (ie: SOFTSTOP_LOW = 0 or SOFTSTOP_HIGH = 100) FINAL_VALUE_CUTOFF is disabled.

7.14.3 Soft Limits

Unlike position alerts, soft limits prevent the stem position from going below or above the conﬁgured limits. If the command signal is trying to drive the position past one of the limits, the yellow LED will blink but the stem position will remain at the set limit.

7.14.4 Travel Accumulator

The travel accumulator is equivalent to a car odometer and sums the total valve movement. Using the user deﬁned stroke length and travel dead-band, the Logix 3400IQ digital positioner keeps a running total of valve movement. When the positioner ﬁrst powers up, high and low dead-band limits are calculated around the present position. When the stem position exceeds the travel dead-band, the movement from the center of the deadband region to the new position is calculated and added to the travel accumulator. From this new position, deadband high and low limits are again calculated.

ﬂowserve.com

Logix 3400IQ Digital Positioner FCD LGENIM3401-00 – 06/06

EXAMPLE: The Logix 3400IQ digital positioner has a default dead-band conﬁguration of 20 percent. The valve has a 4 inch linear stroke. When the valve ﬁrst powers up, the command signal is 50 percent. The unit will calculate a high travel threshold of 70 percent (50 percent present position plus 20 percent dead-band) and a low travel threshold of 30 percent (50 percent present position minus 20 percent dead-band). As long as the stem position remains greater than 30 percent and less than 70 percent, no additions are made to the travel accumulator. Now, assume the stem position moves to 80 percent that is outside the present dead-band. The Logix 3400IQ digital positioner calculates the stem movement and adds this number to the travel accumulator.

80 percent (present position) - 50 percent (previous) = 30 percent movement x 4-inch stroke = 1.2 inches

So, 1.2 inches is added to the travel accumulator. New dead-band thresholds of 100 percent (80 percent present position plus 20 percent dead-band) and 60 percent (80 percent present position minus 20 percent dead-band) are calculated. This process continues as the stem position moves throughout its stroke range.

7.14.5 Cycle Counter

The cycle counter is another means of monitoring valve travel. Unlike the travel accumulator, the stem position must do two things to count as a cycle: exceed the cycle counter dead-band and change direction. A cycle counter limit can also be written into the positioner. If this limit is exceeded, the yellow LED will blink.

7.14.6 Position Deviation

If the stem position differs from the control command by a certain amount for a given length of time, the yellow LED will blink to signify excess deviation. The trip point and settling times are set from the transducer function block.

7.14.7 Advanced Features

NOTE: These features are contained in the transducer function block. Refer to the Reference Manual for a more detailed explanation.

7.14.8 Standard vs. Advanced Diagnostics

Advanced diagnostics models add top, bottom, and supply pressure sensors. This allows for more diagnostic calculations such as loss of pressure, advanced signatures, and troubleshooting.

7.14.9 Temperature and Pressure Units

The desired temperature and pressure units can be set during conﬁguration. Once set, all readings will be displayed in the desired units.

Logix 3400IQ Digital Positioner FCD LGENIM3401-00 – 06/06

7.14.10 Stroke Length

Stroke length is used by the travel accumulator. When the stroke length and units are set, the length is used to determine the total travel accumulated. The travel accumulator will have the units associ ated with stroke.

EXAMPLE: Stroke length is set to four inches. If the valve is moved from 0 percent to 100 percent, four inches will be added to the travel accumulator. The travel accumulator units will be inches. If Stroke length is 90 degrees for a rotary, the travel accumulator will now have units of degree. A 0 percent to 100 percent stroke will add 90 to the travel accumulator.

NOTE: Stroke length is for information only and is not used during calibration.

7.15 Characterization Retention

Once a custom curve has been loaded into the Logix 3400IQ digital positioner’s memory it is retained in the EPROM until it is either edited or replaced. Turning Custom Characterization Active on or off now selects between a linear response (off), or the new custom curve (on). If either of the other two factory curves is selected it will overwrite the custom curve in RAM only. The custom user-deﬁned curve will automatically be activated again when the factory curve is deselected.

7.15.1 Initiating a Valve Signature

A feature of the Logix 3400 positioner is the ability to capture and store a valve diagnostic signature. A signature is the collected data response of the valve to a predeﬁned set of operating conditions. This stored data can later be uploaded to the host system for analysis of potential problems. By comparing a baseline signature, when the valve is new, to subsequent signatures at later times, a rate of change can be tracked which can help predict possible faults in the valve before they happen. This is called ‘predictive maintenance’. It is important to note that the purpose of the positioner is to act as the data acquisition device for the signature. Analysis of the data is not done on the device, but in the supervisory system.

NOTE: Signature data is lost if the positioner is reset or if the power is cycled

7.15.2 System Preparation

WARNING: By deﬁnition, the collection of the signature requires the unmanaged opera-

c

tion of the positioner. Therefore, the process must be in a safe operating mode where unexpected movement of the valve will not cause a hazardous condition.

Before a valve signature can be run, the Transducer Block must Out-of-Service (OOS).

7.15.3 Signature Procedure

The following steps are an example of how to initiate a ramp signature capture.

1. Make sure the process is in safe condition and notify the control room that the valve will

temporarily be taken off-line.

2. Verify preparedness to proceed.

3. Put the Transducer block MODE_BLK OOS

4. Set SIG_START to desired value.

5. Set SIG_STOP to desired value.

6. Set SAMPLE_TIME to desired value (typically 0.3).

7. In SIG_FLAGS, select; STEP_RAMP, PRESS_MEAS.

8. Write values to the Logix 3400IQ digital positioner.

Logix 3400IQ Digital Positioner FCD LGENIM3401-00 – 06/06

9. Set RAMP_RATE to desired value (typically 100).

10. Write value to the Logix 3400IQ digital positioner.

11. In SIG_FLAGS, select BEGIN_SIG.

12. Write value to the Logix 3400IQ digital positioner.

13. The valve will stroke to the beginning position, as deﬁned by SIG_START and will begin ramping

to the desired ending position, as deﬁned by SIG_STOP.

Notice that SIG_COUNTER will increment while this takes place. (Typically approximately 670 data sets will be collected with the above settings and full stroke of the valve. Exact numbers will vary.)

14. SIG_FLAGS indicates SIG COMPLETE.

15. Return the MODE_BLK to auto.

16. Notify control room the valve is back on-line. The stored signature will remain in the Logix

3400IQ digital positioner RAM until the either the unit is powered down, or another signature is taken which overwrites the previous one.

7.16 Step Signature

If a step signature was desired, simply do not select STEP_RAMP in SIG_FLAGS, and then set the STEP_TIME prior to selecting BEGIN_SIG.

7.16.1 Collection of Stored Signature

The collection of the stored signature is accomplished by the host system. It is not part of the device. See host system programming. A simple utility using National Instruments NI-FBUS is available from Flowserve for retrieving a signature ﬁle.

The retrieved ﬁle is stored in a text format that can be imported into other programs for plotting and analysis. Contact Flowserve for more details.

7.17 Glossary

A/D Also called ADC. Analog-to-digital converter. An A/D converts an analog signal into an integer count. This integer count is then used by the microcontroller to process sensor information such as position, pressure, and temperature.

D/A Also called DAC. Digital-to-analog converter. A D/A converts an integer count into an analog output signal. The D/A is used to take a number from the microcontroller and command an external device such as a pressure modulator.

EEPROM (Electrically Erasable Programmable Read Only Memory) A device that retains data even when power is lost. Electrically erasable means that data can be changed. EEPROM have a limited number of times data can be rewritten (typically 100,000 to 1,000,000 writes).

Micro-controller In addition to an integral CPU (microprocessor), the micro-controller has built in memory and I/O functions such as A/D and D/A.

Microprocessor Semiconductor device capable of performing calculations, data transfer, and logic decisions. Also referred to as CPU (Central Processing Unit).

Protocol A set of rules governing how communications messages are sent and received.

Resolution Resolution is a number which indicates the smallest measurement which can be made.

You will often see analog-to-digital (A/D) converters referred to as a 10-bit A/D or a 12-bit A/D. 10-bit and 12-bit are terms which indicate the total number of integer counts which can be used to measure a sensor or other input. To determine the total integer count, raise 2 to the power of the number of bits.

Example: 12-bit A/D

Total integer number = 2

Number of Bits = 2

= 4096

Resolution is the measurement range divided by the maximum integer number.

Example: A valve has a 2-inch stroke and a 12-bit A/D is used to measure position.

Resolution = Stroke/(Maximum Integer for 12-bit) = 2 inch/4096 = 0.000488 inches

Sampling Taking readings at periodic time intervals.

Serial Channel Channel that carries serial transmission. Serial transmission is a method of

sending information from one device to another. One bit is sent after another in a single stream.

16. Reinstall all covers.

9 Optional Vented Design

NOTE: See Figures 19 and 20

A standard Logix 3400IQ 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 3400IQ spool valve chamber (Figures 20 and 21). The main chamber vent is located on the backside of the positioner (see Figure 20). Vented-design Logix 3400IQ 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 ft

WARNING: The back pressure in the main housing must never rise above 2.0 psig (0.14

The spool valve chamber (see Figure 21) must also be vented through the spool valve cover. Vented-design Logix 3400IQ

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.

13 Frequently Asked Questions

Q: I set the Final Value Cutoff Low 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 Final Value Cutoff, the Logix 3400 blink GGGY.

Q: I have Final Value Cutoff 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 Final Value Cutoff to become active. If a positive lower soft stop is written, this stop will take priority over the Final Value Cutoff 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.

IQ LEDs will

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. Perform an actuator pressure calibration.
