Instruction Manual
D102794X012
Specifications
This product was intended for a specific range of service conditions‐‐pressure, pressure drop, process and ambient temperature, temperature variations, process fluid, and possibly other specifications. Do not expose the product to service conditions or variables other than those for which the product was intended. If you are not sure what these conditions or variables are, contact your Emerson sales office other pertinent information that you have available.
for assistance. Provide the product serial number and all
Inspection and Maintenance Schedules
All products must be inspected periodically and maintained as needed. The schedule for inspection can only be determined based on the severity of your service conditions. Your installation might also be subject to inspection schedules set by applicable governmental codes and regulations, industry standards, company standards, or plant standards.
In order to avoid increasing dust explosion risk, periodically clean dust deposits from all equipment.
When equipment is installed in a hazardous area location (potentially explosive atmosphere), prevent sparks by proper tool selection and avoiding other types of impact energy. Control Valve surface temperature is dependent upon process operating conditions.
WARNING
Control valve surface temperature is dependent upon process operating conditions. Personal injury or property damage, caused by fire or explosion, can result if the valve body surface temperature exceeds the acceptable temperature for the hazardous area classification. To avoid an increase of instrumentation and/or accessory surface temperature due to process operating conditions, ensure adequate ventilation, shielding, or insulation of control valve components installed in a potentially hazardous or explosive atmosphere.
Parts Ordering
Whenever ordering parts for older products, always specify the serial number of the product and provide all other pertinent information that you can, such as product size, part material, age of the product, and general service conditions. If you have modified the product since it was originally purchased, include that information with your request.
WARNING
Use only genuine Fisher replacement parts. Components that are not supplied by Emerson Automation Solutions should not, under any circumstances, be used in any Fisher product. Use of components not supplied by Emerson Automation Solutions may void your warranty, might adversely affect the performance of the product and could result in personal injury and property damage.

Installation
WARNING
Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before mounting the product:
D Do not install any system component where service conditions could exceed the limits given in this manual or the limits
on the appropriate nameplates. Use pressure‐relieving devices as required by government or accepted industry codes and good engineering practices.
D Always wear protective gloves, clothing, and eyewear when performing any installation operations.
D Do not remove the actuator from the valve while the valve is still pressurized.
D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the
actuator cannot suddenly open or close the valve.
D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure
from both sides of the valve.
D Vent the pneumatic actuator loading pressure and relieve any actuator spring precompression so the actuator is not
applying force to the valve stem; this will allow for the safe removal of the stem connector.
D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
D The valve packing box might contain process fluids that are pressurized, even when the valve has been removed from the
pipeline. Process fluids might spray out under pressure when removing the packing hardware or packing rings, or when loosening the packing box pipe plug. Cautiously remove parts so that fluid escapes slowly and safely.
D The instrument is capable of supplying full supply pressure to connected equipment. To avoid personal injury and
equipment damage, caused by sudden release of process pressure or bursting of parts, make sure the supply pressure never exceeds the maximum safe working pressure of any connected equipment.
D Severe personal injury or property damage may occur from an uncontrolled process if the instrument air supply is not
clean, dry and oil‐free, or noncorrosive gas. While use and regular maintenance of a filter that removes particles larger than 40 microns will suffice in most applications, check with an Emerson Automation Solutions field office and Industry Instrument air quality standards for use with corrosive gas or if you are unsure about the proper amount or method of air filtration or filter maintenance.
D For corrosive media, make sure the tubing and instrument components that contact the corrosive media are of suitable
corrosiion-resistant material. The use of unsuitable materials might result in personal injury or property damage due to the uncontrolled release of the corrosive media.
D If natural gas or other flammable or hazardous gas is to be used as the supply pressure medium and preventive
measures are not taken, personal injury and property damage could result from fire or explosion of accumulated gas or from contact with hazardous gas. Preventive measures may include, but are not limited to: Remote venting of the unit, re‐evaluating the hazardous area classification, ensuring adequate ventilation, and the removal of any ignition sources.
D To avoid personal injury or property damage resulting from the sudden release of process pressure, use a high‐pressure
regulator system when operating the controller or transmitter from a high‐pressure source.
The instrument or instrument/actuator assembly does not form a gas‐tight seal, and when the assembly is in an enclosed area, a remote vent line, adequate ventilation, and necessary safety measures should be used. Vent line piping should comply with local and regional codes and should be as short as possible with adequate inside diameter and few bends to reduce case pressure buildup. However, a remote vent pipe alone cannot be relied upon to remove all hazardous gas, and leaks may still occur.
D Personal injury or property damage can result from the discharge of static electricity when flammable or hazardous
gases are present. Connect a 14 AWG (2.08 mm flammable or hazardous gases are present. Refer to national and local codes and standards for grounding requirements.
D Personal injury or property damage caused by fire or explosion may occur if electrical connections are attempted in an
area that contains a potentially explosive atmosphere or has been classified as hazardous. Confirm that area classification and atmosphere conditions permit the safe removal of covers before proceeding.

D For instruments with a hollow liquid level displacer, the displacer might retain process fluid or pressure. Personal injury
or property damage due to sudden release of pressure, contact with hazardous fluid, fire, or explosion can be caused by puncturing, heating, or repairing a displacer that is retaining process pressure or fluid. This danger may not be readily apparent when disassembling the sensor or removing the displacer. Before disassembling the sensor or removing the displacer, observe the appropriate warnings provided in the sensor instruction manual.
D Personal injury or property damage, caused by fire or explosion from the leakage of flammable or hazardous gas, can
result if a suitable conduit seal is not installed. For explosion‐proof applications, install the seal no more than 457 mm (18 inches) from the instrument when required by the nameplate. For ATEX applications use the proper cable gland certified to the required category. Equipment must be installed per local and national electric codes.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
D If installing into an existing application, also refer to the WARNING in the Maintenance section.
Instruction Manual
D102794X012
Special Instructions for Safe Use and Installations in Hazardous Locations

Instruments Mounted on Tank or Cage
WARNING
For instruments mounted on a tank or displacer cage, release trapped pressure from the tank and lower the liquid level to a point below the connection. This precaution is necessary to avoid personal injury from contact with the process fluid.
Instruments With a Hollow Displacer or Float
WARNING
For instruments with a hollow liquid level displacer, the displacer might retain process fluid or pressure. Personal injury and property might result from sudden release of this pressure or fluid. Contact with hazardous fluid, fire, or explosion can be caused by puncturing, heating, or repairing a displacer that is retaining process pressure or fluid. This danger may not be readily apparent when disassembling the sensor or removing the displacer. A displacer that has been penetrated by process pressure or fluid might contain:
D pressure as a result of being in a pressurized vessel
D liquid that becomes pressurized due to a change in temperature
D liquid that is flammable, hazardous or corrosive.
Handle the displacer with care. Consider the characteristics of the specific process liquid in use. Before removing the displacer, observe the appropriate warnings provided in the sensor instruction manual.

Description
DVC6000 digital valve controllers (figures 1-1 and 1-2) are communicating, microprocessor-based current-to-pneumatic instruments. In addition to the normal function of converting an input current signal to a pneumatic output pressure, the DVC6000 digital valve controller, using the HART communications protocol, gives easy access to information critical to process operation. You can gain information from the principal component of the process, the control valve itself, using the Field Communicator at the valve, or at a field junction box, or by using a personal computer or operator’s console within the control room.
Using a personal computer and ValveLink software or AMS Suite: Intelligent Device Manager, or a Field Communicator, you can perform several operations
WARNING
Refer to table 1-2 for specifications. Incorrect configuration of a positioning instrument could result in the malfunction of the product, property damage or personal injury.
Specifications for DVC6000 digital valve controllers are shown in table 1-2. Specifications for the Field Communicator can be found in the product manual for the Field Communicator.

Installation
Installation
The DVC6000 can be used with either air or natural gas as the supply medium. If using natural gas as the pneumatic supply medium, natural gas will be used in the pneumatic output connections of the DVC6000 to any connected equipment. In normal operation the unit will vent the supply medium into the surrounding atmosphere unless it is remotely vented. When using natural gas as the supply medium, in a non-hazardous location in a confined area, remote venting of the unit is required. Failure to do so could result in personal injury, property damage, and area re-classification. For hazardous locations remote venting of the unit may be required, depending upon the area classification, and as specified by the requirements of local, regional, and federal codes, rules and regulations. Failure to do so when necessary could result in personal injury, property damage, and area re-classification.
WARNING
Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before proceeding with any Installation procedures:
Always wear protective clothing,
gloves, and eyewear.
Personal injury or property damage may result from fire or explosion if natural gas is used as the supply medium and appropriate preventive measures are not taken. Preventive measures may include, but are not limited to, one or more of the following: Remote venting of the unit, re-evaluating the hazardous area classification, ensuring adequate ventilation, and the removal of any ignition sources. For information on remote venting of this controller, refer to page 2-22.
If installing this into an existing application, also refer to the WARNING at the beginning of the Maintenance section of this instruction manual.
Check with your process or safety engineer for any additional measures that must be taken to protect against process media.
WARNING
To avoid static discharge from the plastic cover when flammable gases or dust are present, do not rub or clean the cover with solvents. To do so could result in a spark that may cause the flammable gases or dust to explode, resulting in personal injury or property damage. Clean with a mild detergent and water only.
WARNING
This unit vents the supply medium into the surrounding atmosphere. When installing this unit in a non-hazardous (non-classified) location in a confined area, with natural gas as the supply medium, you must remotely vent this unit to a safe location. Failure to do so could result in personal injury or property damage from fire or explosion, and area re-classification.
When installing this unit in a hazardous (classified) location remote venting of the unit may be required, depending upon the area classification, and as specified by the requirements of local, regional, and federal codes, rules and regulations. Failure to do so when necessary could result in personal injury or property damage from fire or explosion, and area re-classification.
Vent line piping should comply with local and regional codes and should be as short as possible with adequate inside diameter and few bends to reduce case pressure buildup.
In addition to remote venting of the unit, ensure that all caps and covers are correctly installed. Failure to do so could result in personal injury or property damage from fire or explosion, and area re-classification.

Figure 2-1. FIELDVUE DVC6010 Digital Valve Controller Mounted on Sliding-Stem Actuator with up to 2 Inches Travel
Mounting Guidelines
DVC6010 on Sliding-Stem Actuators Up to 102 mm (4 Inches) of Travel
If ordered as part of a control valve assembly, the factory mounts the digital valve controller on the actuator, makes pneumatic connections to the actuator, sets up, and calibrates the instrument. If you purchased the digital valve controller separately, you will need a mounting kit to mount the digital valve controller on the actuator. See the instructions that come with the mounting kit for detailed information on mounting the digital valve controller to a specific actuator model.
The DVC6010 digital valve controller mounts on sliding-stem actuators with up to 102 mm (4 inch) travel. Figure 2-1 shows a typical mounting on an actuator with up to 51 mm (2 inch) travel. Figure 2-2 shows a typical mounting on actuators with 51 to 102 mm (2 to 4 inch) travel. For actuators with greater than 102 mm (4 inch) travel, see the guidelines for mounting a DVC6020 digital valve controller.
Note
Do not use the stainless steel DVC6010S in high vibration service where the mounting bracket uses standoffs (spacers) to mount to the actuator.
Refer to the following guidelines when mounting on sliding-stem actuators with up to 4 inches of travel. Where a key number is referenced, refer to figure 8-2.
1. Isolate the control valve from the process line pressure and release pressure from both sides of the valve body. Shut off all pressure lines to the actuator, releasing all pressure from the actuator. Use lock-out procedures to be sure that the above measures stay in effect while you work on the equipment.
2. Attach the connector arm to the valve stem connector.

3. Attach the mounting bracket to the digital valve controller housing.
4. If valve travel exceeds 2 inches, a feedback arm extension is attached to the existing 2-inch feedback arm. Remove the existing bias spring (key 78) from the 2-inch feedback arm (key 79). Attach the feedback arm extension to the feedback arm (key 79) as shown in figure 2-2.
5. Mount the digital valve controller on the actuator as described in the mounting kit instructions.
6. Set the position of the feedback arm (key 79) on the digital valve controller to the no air position by inserting the alignment pin (key 46) through the hole on the feedback arm as follows:
For air-to-open actuators (i.e., the actuator stem retracts into the actuator casing or cylinder as air pressure to the casing or lower cylinder increases), insert the alignment pin into the hole marked ‘‘A’’. For this style actuator, the feedback arm rotates counterclockwise, from A to B, as air pressure to the casing or lower cylinder increases.
For air-to-close actuators (i.e., the actuator stem extends from the actuator casing or cylinder as air pressure to the casing or upper cylinder increases), insert the alignment pin into the hole marked ‘‘B’’. For this style actuator, the feedback arm rotates clockwise, from B to A, as air pressure to the casing or upper cylinder increases.

7. Apply anti-seize (key 64) to the pin of the adjustment arm. As shown in figure 2-3, place the pin into the slot of the feedback arm or feedback arm extension so that the bias spring loads the pin against the side of the arm with the valve travel markings.
8. Install the external lock washer on the adjustment arm. Position the adjustment arm in the slot of the connector arm and loosely install the flanged hex nut.
9. Slide the adjustment arm pin in the slot of the connector arm until the pin is in line with the desired valve travel marking. Tighten the flanged hex nut.
10. Remove the alignment pin (key 46) and store it in the module base next to the I/P assembly.
11. After calibrating the instrument, attach the shield with two machine screws.
Note
Do not use the stainless steel DVC6020S in high vibration service where the mounting bracket uses standoffs (spacers) to mount to the actuator.
DVC6020 digital valve controllers use a cam (designed for linear response) and roller as the feedback mechanism. Figure 2-4 shows an example of mounting on sliding-stem actuators with travels from 4 inches to 24 inches. Some long-stroke applications will require an actuator with a tapped lower yoke boss. Figures 2-5 and 2-6 show the DVC6020 mounted on rotary actuators.
As shown in figure 2-5, two feedback arms are available for the digital valve controller. Most long-stroke sliding-stem and rotary actuator installations use the long feedback arm [62 mm (2.45 inches) from roller to pivot point]. Installations on Fisher 1051 size 33 and 1052 size 20 and 33 actuators use the short feedback arm [54 mm (2.13 inches) from roller to pivot point]. Make sure the correct feedback arm is installed on the digital valve controller before beginning the mounting procedure.
DVC6020 on Long-Stroke (4 to 24 Inch Travel) Sliding-Stem Actuators and Rotary Actuators
If ordered as part of a control valve assembly, the factory mounts the digital valve controller on the actuator, makes pneumatic connections to the actuator, sets up, and calibrates the instrument. If you purchased the digital valve controller separately, you will need a mounting kit to mount the digital valve controller on the actuator. See the instructions that come with the mounting kit for detailed information on mounting the digital valve controller to a specific actuator model.
Note
All cams supplied with FIELDVUE mounting kits are characterized to provide a linear response.
Refer to figures 2-4, 2-5, and 2-6 for parts locations. Also, where a key number is referenced, refer to figure 8-3. Refer to the following guidelines when mounting on sliding-stem actuators with 4 to 24 inches of travel or on rotary actuators:
1. Isolate the control valve from the process line pressure and release pressure from both sides of the valve body. Shut off all pressure lines to the pneumatic actuator, releasing all pressure from the actuator. Use lock-out procedures to be sure that the above measures stay in effect while working on the equipment.
2. If a cam is not already installed on the actuator, install the cam as described in the instructions included with the mounting kit. For sliding-stem actuators, the cam is installed on the stem connector.
3. If a mounting plate is required, fasten the mounting plate to the actuator.
4. For applications that require remote venting, a pipe-away bracket kit is available. Follow the instructions included with the kit to replace the existing mounting bracket on the digital valve controller with the pipe-away bracket and to transfer the feedback parts from the existing mounting bracket to the pipe-away bracket.

When using a single-acting direct digital valve controller (relay A or C) on a single-acting actuator connect OUTPUT A to the actuator pneumatic input.
When using a single-acting reverse digital valve controller (relay B) on a single-acting actuator connect OUTPUT B to the actuator diaphragm casing.
Double- Acting Actuators
DVC6000 digital valve controllers on double-acting actuators always use relay A. With no input current, OUTPUT A is at 0 pressure and OUTPUT B is at full supply pressure when the relay is properly adjusted.
To have the actuator stem extend from the cylinder with increasing input signal, connect OUTPUT A to the upper actuator cylinder connection. Connect OUTPUT B to the lower cylinder connection. Figure 2-18 shows the digital valve controller connected to a double-acting piston actuator.

Special Construction to Support Solenoid Valve Testing
In single-acting actuator applications with a solenoid valve installed, the DVC6000 can be configured to test the operation of the solenoid valve. This is accomplished by connecting the “unused” output port from the DVC6000 to the pneumatic line between the solenoid valve and the actuator, as shown in figure 2-19. When single-acting, direct relay C is installed, the “unused” output port is port B. When single-acting, reverse relay B is used, the unused port is port A.

Installation
WARNING
This unit vents the supply medium into the surrounding atmosphere. When installing this unit in a non-hazardous (non-classified) location in a confined area, with natural gas as the supply medium, you must remotely vent this unit to a safe location. Failure to do so could result in personal injury or property damage from fire or explosion, and area re-classification.
When installing this unit in a hazardous (classified) location remote venting of the unit may be required, depending upon the area classification, and as specified by the requirements of local, regional, and federal codes, rules and regulations. Failure to do so when necessary could result in personal injury or property damage from fire or explosion, and area re-classification.
Vent line piping should comply with local and regional codes and should be as short as possible with adequate inside diameter and few bends to reduce case pressure buildup.
In addition to remote venting of the unit, ensure that all caps and covers are correctly installed. Failure to do so could result in personal injury or property damage from fire or explosion, and area re-classification.
The relay output constantly bleeds supply medium into the area under the cover. The vent opening at the back of the housing should be left open to prevent pressure buildup under the cover. If a remote vent is required, the vent line must be as short as possible with a minimum number of bends and elbows.
To connect a remote vent to DVC6010 and DVC6030 digital valve controllers and DVC6005 base unit—remove the plastic vent (key 52, figures
8-2 and 8-5). The vent connection is 3/8 NPT internal. At a minimum, 12.7 mm (1/2-inch) tubing should be used when installing a remote vent to prevent excessive pressure from building up under the cover.
To connect a remote vent to DVC6020 digital valve controllers—replace the standard mounting bracket
(key 74, figures 8-3 and 8-5) with the vent-away bracket (key 74). Install a pipe plug in the vent-away mounting bracket (key 74). Mount the digital valve controller on the actuator as described in the Installation section of this manual. The vent connection is 3/8 NPT internal. At a minimum, 12.7 mm (1/2-inch) tubing should be used when installing a remote vent to prevent excessive pressure from building up under the cover.
Electrical Connections
WARNING
To avoid personal injury resulting from electrical shock, do not exceed the maximum input voltage specified in table 1-2 of this instruction manual, or on the product nameplate. If the input voltage specified differs, do not exceed the lowest specified maximum input voltage.
Select wiring and/or cable glands that are rated for the environment of use (such as hazardous area, ingress protection and temperature). Failure to use properly rated wiring and/or cable glands can result in personal injury or property damage from fire or explosion.
Wiring connections must be in accordance with local, regional, and national codes for any given hazardous area approval. Failure to follow the local, regional, and national codes could result in personal injury or property damage from fire or explosion.
The valve may move in an unexpected direction when power is applied to the DVC6000 digital valve controller. To avoid personal injury and property damage caused by moving parts, keep hands, tools, and other objects away from the valve/actuator assembly when applying power to the instrument.

Control System Requirements
There are several parameters that should be checked to ensure the control system is compatible with the DVC6000 digital valve controller.
HART Filter
Depending on the control system you are using, a HART filter may be needed to allow HART communication. The HART filter is a passive device that is inserted in field wiring from the HART loop. The filter is normally installed near the field wiring terminals of the control system I/O (see figure 2-24). Its purpose is to effectively isolate the control system output from modulated HART communication signals and raise the impedance of the control system to allow HART
VALVE
communication. For more information on the description and use of the HART filter, refer to the separate HART filter instruction manual.
Contact your Emerson Process Management sales office if assistance is needed to determine if your system requires a filter.
Note
A HART filter is typically NOT required for any of the Emerson Process Management control systems, including PROVOXt, RS3t, and DeltaVt systems.

Voltage Available
The voltage available at the DVC6000 digital valve controller must be at least 11 volts DC. The voltage available at the instrument is not the actual voltage measured at the instrument when the instrument is connected. The voltage measured at the instrument is limited by the instrument and is typically less than the voltage available.
As shown in figure 2-25, the voltage available at the instrument depends upon:
the control system compliance voltage
The voltage available at the instrument may be calculated from the following equation:
Voltage Available = [Control System Compliance Voltage (at maximum current)] [filter voltage drop (if a HART filter is used)] [total cable resistance maximum current] [barrier resistance x maximum current].
The calculated voltage available should be greater than or equal to 11 volts DC.

DVC6000 Digital Valve Controllers
Basic Setup (1-1)
Instrument Mode
To setup and calibrate the instrument, the instrument mode must be Out Of Service.
To view the instrument mode, press the Hot Key and select Instrument Mode. If the mode is not Out Of
Service, select Out Of Service from the Instrument Mode menu and press ENTER.

Configuration Protection
To setup and calibrate the instrument, the protection must be set to None with the Field Communicator. If the protection is not None, changing the protection requires placing a jumper across the Auxiliary terminals in the terminal box.
To remove protection:
1. Connect a 4-20 mA source to the instrument.
2. Connect the Field Communicator to the instrument and turn it on.
WARNING
Changes to the instrument setup may cause changes in the output pressure or valve travel. Depending on the application, these changes may upset process control, which may result in personal injury or property damage.
Note
To setup and calibrate the instrument, the protection must be None and the Instrument Mode must be Out Of Service. See Configuration Protection and Instrument Mode at the beginning of this section for information on removing instrument protection and changing the instrument mode.
If you are operating in burst mode, we recommend that you disable burst before continuing with calibration. Once calibration is complete, burst mode may then be turned back on.
3. Press the Hot key on the Field Communicator and select Protection.
Note
If the Auxiliary Terminal Action is configured for Auto Calibration, be sure the jumper remains across the auxiliary terminals until the Field Communicator prompts you to remove it. Removing the jumper too soon will cause the instrument to begin auto travel calibration.
4. From the Protection menu, select None. When prompted by the Field Communicator, temporarily attach the jumper to the AUX + and AUX terminals in the instrument terminal box.
When the DVC6000 digital valve controller is ordered as part of a control valve assembly, the factory mounts the digital valve controller and sets up the instrument as specified on the order. When mounting to a valve in the field, the instrument needs to be setup to match the instrument to the valve and actuator.
Before beginning Basic Setup, be sure the instrument is correctly mounted as described in the Installation section.
Setup Wizard (1-1-1)
To have the Field Communicator automatically setup the instrument using specified actuator information, from the Online Menu select Configure, Guided Setup, and Setup Wizard. Follow the prompts on the Field Communicator display to setup the instrument. Table 4-5 provides the actuator information required to setup and calibrate the instrument.
1. Select travel or pressure control. Travel control is the typical mode of operation.
2. Enter the pressure units: psi, bar, kPa, or kg/cm2.

5. Enter the actuator model or type. If the actuator model is not listed, select Other.
6. Enter the actuator size.
7. Select whether the valve is open or closed under the zero power condition.
WARNING
In the next step, if you answer YES to the prompt for permission to move the valve when the Field Communicator is determining the travel sensor motion, the instrument will move the valve through its full travel range. To avoid personal injury and property damage caused by the release of pressure or process fluid, provide some temporary means of control for the process.
Communicator sets the setup parameters to the values listed in table 3-1. If you select NO for the factory defaults, the setup parameters listed in the table remain at their previous settings.
Typically the Setup Wizard determines the required setup information based upon the actuator manufacturer and model specified. However, if you enter other for the actuator manufacturer or the actuator model, then you will be prompted for setup parameters such as:
Actuator style (spring & diaphragm, piston double-acting without spring, piston single-acting with spring, piston double-acting with spring),
Valve style (rotary or sliding stem),
On Loss of Instrument Signal (valve opens or closes), see Zero Power Condition in the Detailed Setup section.
Feedback connection (rotary-all, sstem-roller, or sstem-standard), see Feedback Connection in the Detailed Setup section.
Travel Sensor motion (increasing air pressure causes the travel sensor shaft to rotate clockwise or counterclockwise). The Field Communicator will ask if it can move the valve to determine travel sensor motion. If you answer yes, the instrument may stroke the valve the full travel span to determine travel sensor rotation. If you answer No, then you will have to specify the rotation for increasing air pressure: clockwise or counterclockwise. (see Travel Sensor Motion in the Detailed Setup section).
Volume booster (indicate if volume booster or quick release is present)
Tuning set (see Tuning Set in the Detailed Setup section).
After completing the setup information, travel is automatically calibrated. Follow the prompts on the Field Communicator display. The calibration procedure uses the valve and actuator stops as the 0% and 100% calibration points. For additional information, refer to Auto Calibrate Travel on page 5-2 of the Calibration section.
When travel calibration is complete, you are asked if you wish to adjust the relay (double-acting only). Select yes to adjust the relay. For additional information, refer to Relay Adjustment on page 5-10 of the Calibration section.

DVC6000 Digital Valve Controllers
If after completing the Setup Wizard the valve seems slightly unstable or unresponsive, you can improve operation by selecting either Performance Tuner or Stabilize/Optimize from the Guided Setup menu. For additional information on using the Performance Tuner, refer to Using the Performance Tuner in this section. For additional information on stabilizing or optimizing valve response, refer to Stabilize/Optimize at the end of this section.
Using the Performance Tuner (1-1-2)
3
Note
Performance Tuner is not available for instrument level AC or HC.
WARNING
During performance tuning the valve may move, causing process fluid or pressure to be released. To avoid personal injury and property damage caused by the release of process fluid or pressure, isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the process fluid.
The Performance Tuner is used to optimize digital valve controller tuning. It can be used with digital valve controllers mounted on most sliding-stem and rotary actuators, including Fisher and other manufacturers’ products. Moreover, because the Performance Tuner can detect internal instabilities before they become apparent in the travel response, it can generally optimize tuning more effectively than manual tuning. Typically, the Performance Tuner takes 3 to 5 minutes to tune an instrument, although tuning instruments mounted on larger actuators may take longer.
Access Performance Tuner by selecting Performance Tuner from the Guided Setup menu. Follow the prompts on the Field Communicator display to optimize digital valve controller tuning.
Stabilizing/Optimizing or (1-1-2) Valve Response
Note
Stabilize/Optimize is only available through the Guided Setup menu for instrument level HC.
WARNING
During Stabilize/Optimize the valve may move, causing process fluid or pressure to be released. To avoid personal injury and property damage caused by the release of process fluid or pressure, isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the process fluid.
If after completing setup and calibration the valve seems slightly unstable or unresponsive, you can improve operation by pressing the Hot Key and selecting Stabilize/Optimize, or select Stabilize/Optimize from the Guided Setup menu.
Stabilize/Optimize permits you to adjust valve response by changing the digital valve controller
If the valve is unstable, select Decrease Response to stabilize valve operation,. This selects the next lower tuning set (e.g., F to E). If the valve response is sluggish, select Increase Response to make the valve more responsive. This selects the next higher tuning set (e.g., F to G).
If after selecting Decrease Response or Increase Response the valve travel overshoot is excessive select Decrease Damping to select a damping value that allows more overshoot. Select Increase Damping to select a damping value that will decrease the overshoot. When finished, select done.

Control Mode—You can change the control mode by selecting Control Mode from the Mode and
Protection menu, or press the Hot Key and select Control Mode.
Control Mode lets you define where the instrument reads its set point. Follow the prompts on the Field Communicator display to choose one of the following control modes: Analog or Digital.
Choose Analog if the instrument is to receive its set point over the 4-20 mA loop. Normally the instrument control mode is Analog.
Choose Digital if the instrument is to receive its set point digitally, via the HART communications link.
A third mode, Test, is also displayed. Normally the instrument should not be in the Test mode. The Field Communicator automatically switches to this mode whenever it needs to stroke the valve during calibration or stroke valve, for example. However, if you abort from a procedure where the instrument is in the Test mode, it may remain in this mode. To take the instrument out of the Test mode, select Control Mode then select either Analog or Digital.
Restart Control Mode—Lets you choose which operating mode you want the instrument to be in after a restart. Access by selecting Restart Control Mode from the Mode and Protection menu. Follow the prompts on the Field Communicator display to define the restart control mode as Resume Last, Analog, or Digital.
Burst Mode (1-2-1-4)
Enabling burst mode provides continuous communication from the digital valve controller. Burst mode applies only to the transmission of burst mode data (analog input, travel target, pressure, and travel) and does not affect the way other data is accessed.
Access to information in the instrument is normally obtained through the poll/response of HART communication. The Field Communicator or the control system may request any of the information that is normally available, even while the instrument is in burst mode. Between each burst mode transmission sent by the instrument, a short pause allows the Field Communicator or control system to initiate a request. The instrument receives the request, processes the response message, and then continues “bursting” the burst mode data.
To enable burst mode, select Burst Mode, and Burst Enable from the Mode and Protection menu.
Burst Enable—Yes or no. Burst mode must be enabled before you can change the burst mode command.
Change Burst Enable—Turns Burst Mode on and off. Actual values are Burst Enable = Disabled(Polled), Enabled.
Burst Command—There are four burst mode commands. Command 3 is recommended for use with the 333 HART Tri-Loop HART-to-analog signal converter. The other three are not used at this time.
Change Burst Command—Allows you to pick the command to be sent from the instrument when Burst Mode is on. Select HART Univ Cmd 1, HART Univ Cmd 2, HART Univ Cmd 3, or DVC6000 Cmd 148.
Cmd 3 Configured Presssure—Command 3 provides the following variables:
Primary variable—analog input in % or ma, Secondary variable—travel target in % of ranged
travel, Tertiary variable—supply or output pressure in psig,
bar, kPa, or kg/cm2. Select Cmd 3 Configured Pressure from the Burst menu to select if the output A, output B, differential (AB), or supply pressure is sent.
Quaternary variable—travel in % of ranged travel.
Protection
Protection—Some setup parameters may require changing the protection with the Field Communicator. To remove protection (change protection to None) requires placing a jumper across the Auxiliary terminals in the terminal box in order to change protection.

Note
If the Auxiliary Terminal Action is configured for Auto Travel Calibration, be sure the jumper remains across the auxiliary terminals until the Field Communicator prompts you to remove it. Removing the jumper too soon will cause the instrument to begin auto travel calibration.
4
WARNING
If the jumper is removed too soon, and auto travel calibration begins, the valve will move full stroke. To avoid personal injury and property damage caused by the release of pressure or process fluid, provide some temporary means of control for the process.
Two levels of protection are available:
Config & Calib—Both setup and calibration are protected. Prohibits changing calibration and protected setup parameters.
None—Neither setup nor calibration is protected. Allows changing calibration and setup parameters.
Table 4-3 lists configurable parameters in the instrument and the requirements for modifying these parameters, in terms of instrument mode and protection.
To change an instrument’s protection, press the Hot key on the Field Communicator and select Protection or from the Online menu, select Configure, Detailed Setup, Mode and Protection, and Protection. Select the desired level of protection. Follow the prompts on the Field Communicator display to set the protection level. If necessary, temporarily attach the jumper to the AUX + and AUX terminals in the instrument

Table 4-5 provides tuning set selection guidelines for Fisher, Baumann, and Gulde actuators. These tuning sets are only recommended starting points. After you finish setting up and calibrating the instrument, you may have to select either a higher or lower tuning set to get the desired response. You can use the Performance Tuner to optimize tuning.
Integral Enable—Yes or No. Enable the integral setting to improve static performance by correcting for error that exists between the travel target and actual travel. Travel Integral Control is enabled by default.
In addition, you can select User Adjusted or Expert, which allows you to modify tuning of the digital valve controller. With User Adjusted, you specify the proportional gain; an algorithm in the Field Communicator calculates the velocity gain and minor loop feedback gain. With Expert you can specify the proportional gain, velocity gain, and minor loop feedback gain.
Note
Use Expert tuning only if standard tuning has not achieved the desired results.
Stabilize/Optimize or Performance Tuner may be used to achieve the desired results more rapidly than Expert tuning.
Integral Gain—Travel Integral Gain is the ratio of the change in output to the change in input, based on the control action in which the output is proportional to the time integral of the input.
Stabilize/Optimize—Stabilize/Optimize permits you to adjust valve response by changing the digital valve controller tuning.
If the valve is unstable, select Decrease Response to stabilize valve operation. This selects the next lower tuning set (e.g., F to E). If the valve response is sluggish, select Increase Response to make the valve more responsive. This selects the next higher tuning set (e.g., F to G).
If after selecting Decrease Response or Increase Response the valve travel overshoot is excessive, select Decrease Damping to select a damping value that allows more overshoot. Select Increase Damping to select a damping value that will decrease the overshoot. When finished, select done.

Performance Tuner
Note
The Performance Tuner is not available for instrument level HC.
The Performance Tuner is used to optimize digital valve controller tuning. It can be used with digital valve controllers mounted on most sliding-stem and rotary actuators, including Fisher and other manufacturers’ products. Moreover, because the performance tuner can detect internal instabilities before they become apparent in the travel response, it can generally optimize tuning more effectively than manual tuning. Typically, the performance tuner takes 3 to 5 minutes to tune an instrument, although tuning instruments mounted on larger actuators may take longer.
Integral Settings (1-2-2-1-2)
Integral Dead Zone—A window around the Primary Setpoint in which integral action is disabled. This feature is used to eliminate friction induced limit cycles around the Primary Setpoint when the integrator is active. The Dead Zone is configurable from 0% to 2%, corresponding to a symmetric window from 0% to +/2% around the Primary Setpoint. Default value is 0.25%.

Detailed Setup
Travel/Pressure Control (1-2-2-2)
Travel/Pressure Select—Determines if the instrument is set up for position or pressure control. Select Travel, Pressure, Travel with Pressure Fallback/Auto recovery or Travel with Pressure Fallback/Manual Recovery. If the travel sensor fails, and Travel with Pressure Fallback/Auto Recovery is selected, it will return to travel control when the travel sensor starts working again. Travel with Pressure Fallback/Manual recovery will stay in pressure control until Travel Pressure Select is changed to Travel or Travel with Pressure Fallback/Auto recovery. It is not necessary to enable the Travel Sensor Alert for Pressure Fallback to occur.
Cutoffs and Limits (1-2-2-2-2)
Cutoff Hi
Travel Cutoff High defines the high cutoff point for the travel in percent (%) of ranged input current. Above this cutoff, the travel target is set to 123.0% of the ranged input current. When a Travel Cutoff High is set, the Travel Limit High is deactivated, since only one of these parameters can be active. Travel Cutoff Hi is deactivated by setting it to 125.0%.
Pressure Cutoff Hi defines the high cutoff point for the pressure in percent (%) of pre-characterized setpoint. Above this cutoff, the pressure target is set to 123.0%. A Pressure Cutoff Hi of 99.5% is recommended to ensure valve goes fully open. Pressure Cutoff Hi is deactivated by setting it to 125%.
Cutoff Lo
Travel Cutoff Low defines the low cutoff point for the travel set point. Travel Cutoff Low can be used to ensure proper seat load is applied to the valve. When below the travel cutoff low, the output is set to zero or to full supply pressure, depending upon the zero power condition. A Travel Cutoff Low of 0.5% is recommended to help ensure maximum shutoff seat loading. When a Travel Cutoff Low is set, the Travel Limit Low is deactivated, since only one of these parameters can be active. Travel Cutoff Low is deactivated by setting it to −25%.
Travel Limit Hi—Defines the high limit for the travel in percent (%) of ranged travel. It is the maximum allowable travel (in percent of ranged travel) for the valve. During operation, the travel target will not exceed this limit. When a Travel Limit High is set, the Travel Cutoff High is deactivated, since only one of these parameters can be active. Travel Limit High is deactivated by setting it to 125.0%
Travel Limit Lo—Travel Limit Low defines the low limit for the travel in percent (%) of ranged travel. It is the minimum allowable travel (in percent of ranged travel) for the valve. During operation, the travel target will not exceed this limit. When a Travel Limit Low is set, the Travel Cutoff Low is deactivated, since only one of these parameters can be active. Travel Limit Low is deactivated by setting it to −25.0%.
Change Travel Limits—Allows you to set hi and lo travel limits. Setting a travel limit will eliminate the corresponding Tvl/Press Cutoff.
Pressure Control (1-2-2-2-3)
Pressure Range Hi—The high end of output pressure range. Enter the pressure that corresponds with 100% valve travel when Zero Power Condition is closed, or 0% valve travel when Zero Power Condition is open. This pressure must be greater than the Pressure Range Lo.
Pressure Range Lo—The low end of the output pressure range. Enter the pressure that corresponds to 0% valve travel when Zero Power Condition is closed, or 100% valve travel when Zero Power Condition is open. This pressure must be less than the Pressure Range Hi.
End Point Pressure Control (1-2-2-2-5)
Note
End Point Pressure Control is only available for instrument level ODV.

Pressure Cutoff Lo defines the low cutoff point for the pressure in percent (%) of pre-characterized setpoint. Below this cutoff, the pressure target is set to 23%. A Pressure Cutoff Lo of 0.5% is recommended to help ensure maximum shutoff seat loading. Pressure Cutoff Lo is deactivated by setting it to −25.0%
Change Cutoffs—Allows you to set hi and lo cutoffs. When a cutoff is set the corresponding travel or pressure limit will be disabled.
September 2013
End Pt Control Enab— Select Yes or No. End Point Pressure Control allows the digital valve controller to pull back from saturation of the pneumatic output after reaching the travel extreme. Rather than having the instrument provide full supply pressure (saturation) continuously at the travel extreme, the digital valve controller switches to an End Point Pressure Control where the output pressure (pressure controller set point) to the actuator is maintained at a certain value. This value is configured through the
4-9
DVC6000 Digital Valve Controllers
Upper Operating Pressure feature. Because the digital valve controller is constantly in control and not allowed to reach a dormant or saturated state, it is constantly testing its own pneumatic system. If there is an output pressure deviation, for example, the instrument will issue an alert. To ensure there is an alert when an output pressure deviation occurs, setup the alert as described under Pressure Deviation Alert.
PST Start Pt—Defines the travel stop the valve needs to be at before a partial stroke test can be initiated. Also defines the travel stop for end point pressure control. Setting this value to Not Configured will disable partial stroke tests and end point pressure control.
4
EPPC Setup Point—Used in conjunction with End Point Pressure Control, Pressure Set Point allows the user to select a pressure to be delivered by the instrument at the travel extreme. For a fail-closed valve, this pressure must be sufficient to maintain the fully open position. For a fail-open valve, this pressure (which is automatically set to supply pressure) must be sufficient to fully close the valve and maintain its rated shutoff classification. For double-acting spring return actuators, this is the differential pressure required to either maintain the fully open or fully closed position, depending on the valve and actuator configuration. For a double-acting actuator without springs with a fail-close valve, this is 95% of the supply pressure. If the valve is fail-open, the upper operating pressure for all actuator is set to the supply pressure.
EPPC Saturation Time—Pressure Saturation Time is the amount of time the digital valve controller stays in hard cutoff before switching to pressure control. Default is 45 seconds.

Input Characterization (1-2-2-3)
Input Characterization defines the relationship between the travel target and ranged set point. Ranged set point is the input to the characterization function. If the zero power condition equals closed, then a set point of 0% corresponds to a ranged input of 0%. If the zero power condition equals open, a set point of 0% corresponds to a ranged input of 100%. Travel target is the output from the characterization function.
To select an input characterization, select Input Characterization from the Response Control menu. You can select from the three fixed input characteristics shown in figure 4-1 or you can select a custom characteristic. Figure 4-1 shows the relationship between the travel target and ranged set point for the fixed input characteristics, assuming the Zero Power Condition is configured as closed.

Detailed Setup
You can specify 21 points on a custom characteristic curve. Each point defines a travel target, in % of ranged travel, for a corresponding set point, in % of ranged set point. Set point values range from −6.25% to 106.25%. Before modification, the custom characteristic is linear.
Custom Characterization Table (1-2-2-4)
Select Custom Characterization Table from the Response Control menu and follow the prompts to define a custom input character.
With input characterization you can modify the overall characteristic of the valve and instrument combination. Selecting an equal percentage, quick opening, or custom (other than the default of linear) input characteristic modifies the overall valve and instrument characteristic. However, if you select the linear input characteristic, the overall valve and instrument characteristic is the characteristic of the valve, which is determined by the valve trim (i.e., the plug or cage).
Dynamic Response (1-2-2-5)
SP Rate Open (Minimum Opening Time in firmware 26)—Maximum rate (% of valve travel per second) at which the digital valve controller will move to the open position regardless of the rate of input current change. A value of 0 will deactivate this feature and allow the valve to stroke open as fast as possible. In firmware 10 and below this parameter should be set to 0.
SP Rate Close (Minimum Closing Time in firmware 26)—Maximum rate (% of valve travel per second) at which the digital valve controller will move to the close position regardless of the rate of input current change. A value of 0 will deactivate this feature and allow the valve to stroke close as fast as possible. In firmware 10 and below this parameter should be set to 0.
Note
Set Point Filter Time (Lag Time) is only available for instrument level HC, AD, and PD, firmware 7, 9, 10, and 11.
Set Point Filter Time (Lag Time)—Slows the response of the digital valve controller. A value ranging from 0.2 to 10.0 can be used for noisy or fast processes to improve closed loop process control. Entering a value of 0.0 will deactivate the lag filter. In Firmware 7, 9, and 10 this parameter should be set to 0.
Note
Lead/Lag is only available for instrument level ODV.
4
Lead/Lag Set Point Filter—ODV devices have access to a lead-lag input filter that can be used to improve a valve’s dynamic response. The lead-lag input filter is part of the set point processing routine that reshapes the input signal before it becomes travel set point. Lead-lag filters are characterized by lead and lag time constants.
When the valve is in its active control region (off the seat), the lead-lag filter improves small amplitude response by momentarily overdriving the travel set point. This is useful when the actuator is large and equipped with accessories. As a result, any volume boosters that are present will be activated. The longer the lag time, the more pronounced the overdrive. Since the lead-lag input filter is used to enhance the dynamic response of a control valve, filter parameters should be set after the tuning parameters have been established.
When the valve is at its seat, the lead-lag filter also has a boost function that sets the initial conditions of the filter artificially low so that small amplitude signal changes appear to be large signal changes to the filter. The boost function introduces a large spike that momentarily overdrives the instrument and activates any external volume boosters that may be present. The lead-lag boost function is normally disabled except for those cases where the valve must respond to small command signals off the seat. By setting the lead/lag ratio in the opening and closing directions to
1.0, the boost function can be enabled without introducing lead-lag dynamics in the active control region. See table 4-7 for typical lead-lag filter settings.

pressure. If the difference exceeds the Pressure Deviation Alert Point for more than the pressure deviation time, the Pressure Deviation Alert is set. It remains set until the difference between the target pressure and the actual pressure is less than the Pressure Deviation Alert Point. The pressure deviation alert point and deviation alert time are configurable and can be disabled altogether. Factory default is Yes.
Pressure Deviation Alert Point— The alert point for the difference between the pressure target and the actual pressure. When the difference exceeds the alert point for more than the Pressure Deviation Time, the Pressure Deviation Alert is set. After completion of the Setup Wizard or Auto Travel calibration a default value of 2 psi is set. This will generate an alert when the actuator pressure is not
within $2 psi of the target pressure.
Pressure Deviation Time— The time, in seconds, that the pressure deviation must exceed the Pressure Deviation Alert Point before the alert is set. The Pressure Deviation Time is set to 30 seconds by default.

PST Press Limit (double-acting actuators)— During the Setup Wizard or Auto Travel Calibration, the PST Press Limit will be set to a negative value for actuators where the Partial Stroke Start Point is opposite of the Zero Power Condition (e.g., Partial Stroke Start Point = Open and Zero Power Condition = Closed) and to a positive value for actuators where the Partial Stroke Start Point is the same as the Zero Power Condition.
Note
The Max Travel Movement is the percentage of total span that the valve moves away from its operating state towards its fail state during a Partial Stroke Test.
Stroke Speed—The stroke speed can be set for 1%/second, 0.5%/second, 0.25%/second,
0.12%/second, or 0.06%/second. The default value for Partial Stroke Speed is 0.25%/second.
4-20
Note
In order to manually set the partial stroke pressure limit with the correct value, you must be able to run a valve signature test using ValveLink software. It is then possible to set the partial stroke pressure limit with the Field Communicator, using the information generated by the valve signature test.
September 2013
Detailed Setup
To manually set the partial stroke pressure limit, disable the travel deviation alert by setting Travel Dev Alert Pt to 125%. Also disable “end point pressure control” and disable the partial stroke pressure limit by setting the values shown in table 4-9.
Run the partial stroke test using the Field Communicator. Once the test is completed download the partial stroke test results using ValveLink software.
Select the Press/Time radio button from the partial stroke valve signature graph. If actuator pressure starts high and moves low, find the minimum actuator pressure, Pmin. Otherwise, find the maximum actuator pressure, Pmax. Use table 4-10 to estimate the partial stroke pressure limit.
The default value is 0. For double-acting valves, the differential pressure is
used.

DVC6000 Digital Valve Controllers
Calibration Overview
When a DVC6000 digital valve controller is ordered as part of a control valve assembly, the factory mounts the digital valve controller on the actuator and connects the necessary tubing, then sets up and calibrates the controller. For remote-mounted digital valve controllers, the DVC6005 base unit ships separately from the control valve and does not include tubing, fittings or wiring.
For digital valve controllers that are ordered separately, recalibration of the analog input or pressure sensors generally is unnecessary. However, after mounting on an actuator, perform the initial setup (either auto or manual), then calibrate travel by selecting Calibrate, Travel Calibration, and Auto Calibration from the Configure menu. For more detailed calibration information, refer to the following
5
calibration procedures, available from the Calibrate menu:
Travel Calibration
Auto Calibration —This procedure automatically calibrates the travel. The calibration procedure uses the valve and actuator stops as the 0% and 100% calibration points.
Manual Calibration —This procedure permits manual calibration of the travel. This calibration procedure allows you to determine the 0% and 100% calibration points and obtain the optimum linearity on a sliding-stem valve.
Sensor Calibration
Pressure Sensors—This procedure permits calibrating the three pressure sensors. Normally the sensors are calibrated at the factory and should not need calibration.
Travel Sensor—This procedure permits calibrating the travel sensor. Normally the travel sensor is calibrated at the factory. Calibrating the travel sensor should only be necessary if the travel sensor is replaced.
Analog In—This procedure permits calibrating the analog input sensor. Normally the sensor is calibrated at the factory and should not need calibration.
Relay Adjustment—This procedure permits adjustment of the pneumatic relay.
Restore Factory Settings—This procedure permits you to restore the calibration settings back to the factory settings.
To display the calibrate menu, from the Online menu, select Configure and Calibrate.
Note
The Instrument Mode must be Out Of Service and the Protection set to None before the instrument can be calibrated.
If you are operating in burst mode, we recommend that you disable burst before continuing with calibration. Once calibration is complete, burst mode may then be turned back on.
WARNING
During calibration the valve will move full stroke. To avoid personal injury and property damage caused by the release of process fluid or pressure, isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the process fluid.
Travel Calibration
There are two procedures available for calibrating travel:
Auto CalibrationManual Calibration
Once the travel is calibrated by performing either the Auto Calibration or Manual Calibration procedures, the travel calibration can be “touched-up” using Touch-Up Travel Calibration.
Auto Calibration (1-3-1-1)
User interaction is only required with Auto Calibrate Travel when the feedback connection is SStem ­Standard (Sliding Stem - Standard). A feedback connection of Rotary - All, SStem - Roller (Sliding Stem - Roller) requires no user interaction and you can start with step 6.
For a SStem - Standard feedback connection, interaction provides a more accurate crossover adjustment. Setting crossover establishes the zero degree point for the geometric correction used to translate the rotary motion observed by the travel sensor into the linear motion of the sliding-stem valve.

Calibration
When a double-acting actuator is used, you will be prompted to run the Relay Adjustment when Auto Travel Calibration is selected. Select Yes to adjust the relay. Select No to proceed with Auto Travel Calibration. For additional information, refer to Relay Adjustment in this section.
Select Calibrate, Travel Calibration, Auto Calibration, then follow the prompts on the Field Communicator display to automatically calibrate travel.
1. Select the method of crossover adjustment: manual, last value, or default. Manual is the recommended choice. If you select Manual, the Field Communicator will prompt you to adjust the crossover in step 3.
If you select Last Value, the crossover setting currently stored in the instrument is used and there are no further user interactions with the auto-calibration routine (go to step 6). Use this selection if you cannot use manual, such as when you cannot see the valve.
If you select Default, an approximate value for the crossover is written to the instrument and there are no further user interactions with the auto-calibration routine (go to step 6). Use this selection only as a last resort. Default assumes a midrange position on the travel sensor as the crossover point, however, this may not be an appropriate value to use for crossover because of variations in mounting and travel sensor calibration.
2. The instrument seeks the high and low drive points and the minor loop feedback (MLFB) and output bias. No user interaction is required in this step. For a description of these actions see step 6.
3. If you select Manual in step 1, you are asked to select an adjustment source, either analog or digital. If you use a current source to adjust the crossover, select Analog and go to step 4. If you wish to adjust the current source digitally, select Digital and go to step 5.
4. If you selected Analog as the crossover adjustment source, the Field Communicator prompts you to adjust the current source until the feedback arm is 90° to the actuator stem, as shown in figure 5-1. After you have made the adjustment, press OK and go to step 6.
5. If you selected Digital as the crossover adjustment source, the Field Communicator displays a menu to allow you to adjust the crossover.
Select the direction and size of change required to set the feedback arm so it is 90° to the actuator stem, as shown in figure 5-1. Selecting large, medium, and small adjustments to the crossover causes changes of

approximately 10.0°, 1.0°, and 0.1°, respectively, to the rotation of the feedback arm.
If another adjustment is required, repeat step 5. Otherwise, select Done and go to step 6.
6. The remainder of the auto calibration procedure is automatic.
During calibration, the instrument seeks the high and low end points and the minor loop feedback (MLFB) and output bias. By searching for the end points, the instrument establishes the limits of physical travel, i.e., the actual travel 0 and 100% positions. This also determines how far the relay beam swings to calibrate the sensitivity of the beam position sensor.
Adjusting the minor loop feedback bias is done around mid travel. The valve position is briefly moved back and forth to determine the relay beam position at quiescence. Essentially, it establishes the zero point for the Minor Loop Feedback circuit. The back and forth motion is performed to account for hysteresis.
Adjusting the output bias aligns the travel set point with the actual travel by computing the drive signal required to produce 0% error. This is done while the valve is at 50% travel, making very small adjustments. Calibration is complete when the “Auto Calibration has completed” message appears.
7. Place the instrument In Service and verify that the travel properly tracks the current source.
If the unit does not calibrate, refer to table 5-1 for error messages and possible remedies.

The analog input signal to the instrument must be greater than 3.8 mA. Adjust the current output from the control system or the current source to provide at least 4.0 mA.
The Instrument Mode must be Out of Service and the Protection must be None before the instrument can be calibrated. For information on changing instrument protection and mode, see the beginning of this section.
The problem may be one or the other of the following:
1. The tuning set selected is too low and the valve does not reach an end point in the allotted time. Press the Hot Key, select Stabilize/Optimize then Increase Response (selects next higher tuning set).
2. The tuning set selected is too high, valve operation is unstable and does not stay at an end point for the allotted time. Press the Hot Key, select Stabilize/Optimize then Decrease Response (selects next lower tuning set).
Prior to receiving this message, did the instrument output go from zero to full supply? If not, verify instrument supply pressure by referring to the specifications in the appropriate actuator instruction manual. If supply pressure is correct, check instrument pneumatic components (I/P converter and relay).
If the instrument output did go from zero to full supply prior to receiving this message, then verify proper mounting by referring to the appropriate mounting procedure in the Installation section. Verify travel sensor adjustment by performing the appropriate Travel Sensor Adjust procedure in the Calibration section. Making the crossover adjustment with the valve positioned at either end of its travel will also cause this message to appear.
The instrument may have been taken out of service by a primary master. Put the instrument into service with the primary master or cycle the power off and on.

Once the travel is calibrated by performing either the Auto or Manual Calibration procedure, the travel calibration can be “touched-up” by shorting the Auxiliary Terminal Connections for 3 to 5 seconds to activate Touch-Up Calibration. Touch-Up Travel Calibration uses Last Value for the crossover adjustment. You can abort the procedure by shorting the auxiliary terminals for 1 second.
To enable Touch-Up Travel Calibration the Aux Terminal Mode must be set to Auto Calibration. The instrument Operational Status during calibration is Calibration in Progress.

controller travel whenever the I/P converter or relay is replaced. Do not use Touch-Up calibration for initial calibration when mounting the instrument on an actuator, or if the travel sensor assembly or printed wiring board assembly was replaced.
You can use Touch-Up Travel Calibration to calibrate the digital valve controller if you suspect calibration has changed due to drift. However, prior to initiating Touch-Up Travel Calibration, perform a Valve Signature diagnostic test, using ValveLink software. This will capture the as-found data for future root cause analysis.
