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.

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. Equipement 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.

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.

Description

DVC6200 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 DVC6200 digital valve controller, using the HARTr 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 with the DVC6200 digital valve controller. You can obtain general information concerning software revision level, messages, tag, descriptor, and date.

Instruction Manual

D103409X012

The feedback system for the DVC6200 digital valve controller utilizes a magnetic assembly for linkage‐less, non‐contacting position measurement. In order to prevent inadvertent stem movement while the instrument is in operation, magnetic tools (such as a magnetic‐tipped screwdriver) should not be used.

Note

The magnet assembly may be referred to as a magnetic array in user interface tools.

CAUTION

The magnet assembly material has been specifically chosen to provide a long‐term stable magnetic field.

However, as with any magnet, care must be taken when handling the magnet assembly. Another high powered magnet placed in close proximity (less than 25 mm) can cause permanent damage. Potential sources of damaging equipment include, but are not limited to: transformers, DC motors, stacking magnet assemblies.

CAUTION

General Guidelines for use of High Power Magnets with Positioners

Use of high power magnets in close proximity to any positioner which is operating a process should be avoided. Regardless of the positioner model, high power magnets can affect the positioner’s ability to control the valve. Technicians should avoid the use of high power magnets in close proximity with any positioner.

Use of Magnetic Tools with the DVC6200

D Magnetic Tip Screw Drivers – Magnetic tip screw drivers can be used to work on the DVC6200. However, they should

not be brought in close proximity to the magnet assembly (located at the back of the instrument) during process operations.

D Calibrator Strap Magnets

Normally, these calibrators would not be used while an instrument is controlling the process. High power magnets should be kept at least 15 cm (6 inches) from the DVC6200.

Note

As a general rule, do not use less than 60% of the magnet assembly travel range for full travel measurement. Performance will decrease as the assembly is increasingly subranged.

The linear magnet assemblies have a valid travel range indicated by arrows molded into the piece. This means that the hall sensor (on the back of the DVC6200 housing) has to remain within this range throughout the entire valve travel. See figure 2‐2. The linear magnet assemblies are symmetrical. Either end may be up.

– These are high power magnets used to hold 4-20 ma calibrators.

Mounting the DVC6215 Feedback Unit

If ordered as part of a control valve assembly, the factory mounts the feedback unit on the actuator, makes pneumatic connections to the actuator, sets up, and calibrates the instrument. If you purchased the feedback unit separately, you will need a mounting kit to mount the feedback unit on the actuator. See the instructions that come with the mounting kit for detailed information on mounting the feedback unit to a specific actuator model.

The DVC6215 housing is available in two different configurations, depending on the actuator mounting method. Figure 2‐7 shows the available configurations. The feedback system for the DVC6215 feedback unit utilizes a magnetic assembly for true linkage‐less, non‐contacting position measurement. In order to prevent inadvertent stem movement while the instrument is in operation, magnetic tools (such as a magnetic‐tipped screwdriver) should not be used.

There are a variety of mounting brackets and kits that are used to mount the DVC6215 to different actuators.

Note

The DVC6215 feedback unit uses the same mountings as the DVC6200 digital valve controller.

However, despite subtle differences in fasteners, brackets, and connecting linkages, the procedures for mounting can be categorized as follows:

D Sliding‐stem linear actuators

D Fisher rotary actuators

D GX actuator

D Quarter‐turn actuators

See figure 2‐3 for examples of the different travel feedback magnet assemblies.

Sliding‐Stem Linear Actuators up to 210 mm (8.25 Inches) of Travel

The DVC6215 feedback unit has linkage‐less, non‐contact feedback on sliding‐stem actuators with up to 210 mm (8.25 inches) travel. Figure 2‐9 shows a typical mounting on a sliding stem actuator. For actuators with greater than 210 mm (8.25 inches) travel, see the guidelines on page 20.

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 mounting bracket to the actuator.

WARNING

To avoid personal injury or property damage resulting from bursting of parts, do not exceed maximum supply pressure.

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 30.

Severe personal injury or property damage may occur from an uncontrolled process if the instrument supply medium is not clean, dry, oil‐free, and noncorrosive. While use and regular maintenance of a filter that removes particles larger than 40 micrometers in diameter will suffice in most applications, check with an Emerson Process Management field office and industry instrument air quality standards for use with corrosive air or if you are unsure about the amount of air filtration or filter maintenance.

WARNING

When using natural gas as the supply medium, or for explosion proof applications, the following warnings also apply:

D Remove electrical power before removing the housing cap. Personal injury or property damage from fire or explosion

may result if power is not disconnected before removing the cap.

D Remove electrical power before disconnecting any of the pneumatic connections.

D When disconnecting any of the pneumatic connections or any pressure retaining part, natural gas will seep from the

unit and any connected equipment into the surrounding atmosphere. 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: ensuring adequate ventilation and the removal of any ignition sources.

Instruction Manual

D103409X012

The DVC6200 can be used with 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 DVC6200 to any connected equipment. In normal operation the unit will vent the supply medium into the surrounding atmosphere unless it is remotely vented.

Natural Gas Certified, Single Seal instruments can be identified by the natural gas approval label shown in figure 2‐22. The Natural Gas Certified, Single Seal device option simplifies conduit sealing requirements. Read and follow all local, regional, and federal wiring requirements for natural gas installations. Contact your Emerson Process Management sales office for information on obtaining a Natural Gas Certified, Single Seal DVC6200 digital valve controller.

Figure 2‐22. Gas Certified Label

LABEL LOCATED ON TOP OF TERMINAL BOX

Supply pressure must be clean, dry air that meets the requirements of ISA Standard 7.0.01.

Alternatively, natural gas must be clean, dry, oil‐free, and noncorrosive. H

S content should not exceed 20 ppm.

If you are using a 67CFR filter regulator with standard 5 micrometer filter, connect the supply line to the 1/4 NPT IN connection and attach tubing from the output connection on the filter regulator to the SUPPLY connection on the instrument. If you are using an integral mounted 67CFR filter regulator, connect the supply to the IN connection on the regulator.

Output Connection

A factory mounted digital valve controller has its output piped to the supply connection on the actuator. If mounting the digital valve controller in the field, connect the 1/4 NPT digital valve controller output connection to the pneumatic actuator input connection.

Single‐Acting Actuators

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.

Page 35

Instruction Manual

D103409X012

Installation

December 2013

Double‐Acting Actuators

DVC6200 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. To have the actuator stem retract into the cylinder with increasing input signal, connect OUTPUT A to the lower actuator cylinder connection. Connect OUTPUT B to the upper cylinder connection.

Special Construction to Support Solenoid Valve Testing

Note

Solenoid valve testing is only available for instrument level ODV.

In single‐acting actuator applications with a solenoid valve installed, the DVC6200 can be configured to test the operation of the solenoid valve. This is accomplished by connecting the “unused” output port from the DVC6200 to the pneumatic line between the solenoid valve and the actuator, as shown in figure 2‐23. 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.

Vent

WARNING

Personal injury or property damage can occur from cover failure due to overpressure. Ensure that the housing vent opening is open and free of debris to prevent pressure buildup under the cover.

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, should be as short as possible with a minimum inside diameter of 12.7 mm (1/2‐inch), 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 constantly bleeds a small amount of supply medium into the area under the cover. The vent opening, located below the wiring terminal box on the side of the housing, should be left open to prevent pressure buildup under the cover. If a remote vent is required, the vent lines must be as short as possible with a minimum number of bends and elbows.

To connect a remote vent, remove the plastic vent. The vent connection is 3/8 NPT. 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.

Wiring and Electrical Connections

WARNING

To avoid personal injury resulting from electrical shock, do not exceed maximum input voltage specified in table 1‐2 of this quick start guide, or on the product nameplate. If the input voltage specified differs, do not exceed the lowest specified maximum input voltage.

WARNING

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.

Page 37

Instruction Manual

D103409X012

Personal injury or property damage caused by fire or explosion may occur if this connection is attempted in a potentially explosive atmosphere or in an area that has been classified as hazardous. Confirm that area classification and atmosphere conditions permit the safe removal of the terminal box cover before proceeding.

The valve may move in an unexpected direction when power is applied to the DVC6200 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.

Wiring Practices

Control System Requirements

There are several parameters that should be checked to ensure the control system is compatible with the DVC6200 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 2‐27). 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 communication. For more information on the description and use of the HART filter, refer to the appropriate HART filter instruction manual.

To determine if your system requires a filter contact your Emerson Process Management sales office.

Note

A HART filter is typically NOT required for any of the Emerson Process Management control systems, including PROVOXt, RS3t, and DeltaVt systems.

VALVE

Voltage Available

The voltage available at the DVC6200 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 2‐28, the voltage available at the instrument depends upon:

D the control system compliance voltage

D if a filter, wireless THUM adapter, or intrinsic safety barrier is used, and

D the wire type and length.

The control system compliance voltage is the maximum voltage at the control system output terminals at which the control system can produce maximum loop current.

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.

Table 2‐2 lists the resistance of some typical cables.

The following example shows how to calculate the voltage available for a Honeywellt TDC2000 control system with a HF340 HART filter, and 1000 feet of Belden

9501 cable:

Voltage available = [18.5 volts (at 21.05 mA)] - [2.3 volts] - [48 ohms  0.02105 amps]

Voltage available = [18.5] - [2.3] - [1.01]

Voltage available = 15.19 volts

Calculate Voltage Available at the Instrument as follows:

– Filter voltage drop (if used)

Example Calculation

18.5 volts (at 21.05 mA)

– 2.3 volts (for HF300 filter)

– Intrinsic safety barrier resistance (if used) x maximum loop current – 2.55 volts (121 ohms x 0.02105 amps)

– Smart Wireless THUM adapter voltage drop (if used)

– Total loop cable resistance x maximum loop current – 1.01 volts (48 ohms x 0.02105 amps for

1000 feet of Belden 9501 cable)

= Voltage available at the instrument

= 15.19 volts, available—if safety barrier (2.55 volts) is not used

NOTES:

Obtain filter voltage drop. The measured drop will be different than this value. The measured filter voltage drop

depends upon control system output voltage, the intrinsic safety barrier (if used), and the instrument. See note 3.

The voltage drop of the THUM adapter is linear from 2.25 volts at 3.5 mA to 1.2 volts at 25 mA.

The voltage available at the instrument is not the voltage measured at the instrument terminals. Once the instrument is

connected, the instrument limits the measured voltage to approximately 9.0 to 10.5 volts.

Basic Setup

Field Communicator Configure > Guided Setup (1‐1)

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.

When the DVC6200 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 set up 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

Field Communicator Configure > Guided Setup > Setup Wizard (1‐1‐1)

Follow the prompts on the Field Communicator display to automatically setup the instrument using specified actuator information. Table 4‐4 provides the actuator information required to setup and calibrate the instrument.

1. Enter the instrument family; select DVC6200.

2. Select travel or pressure control. Travel control is the typical mode of operation. Refer to page 56 for additional information on setting Travel/Pressure Control.

3. Enter the pressure units: psi, bar, kPa, or kg/cm

4. Enter the maximum instrument supply pressure.

After entering the maximum instrument supply pressure, the Setup Wizard prompts you for actuator information.

5. Enter the manufacturer of the actuator on which the instrument is mounted. If the actuator manufacturer is not listed, select Other.

6. Enter the actuator model or type. If the actuator model is not listed, select Other.

7. Enter the actuator size.

8. Select whether the valve is open or closed under the zero power condition.

9. Specify if a volume booster or quick release valve is present.

10. Specify if factory defaults should be used for Basic Setup. If you select YES for factory default, the Field 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 on page 70.

WARNING

If you answer YES to the prompt for permission to move the valve when the Setup Wizard 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, isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the process fluid.

Travel Sensor motion (increasing or decreasing air pressure causes the magnet assembly to move up or down or the rotary shaft to turn clockwise or counterclockwise) The Setup Wizard asks if it can move the valve to determine travel sensor motion. If you answer Yes, the instrument will stroke the valve the full travel span to determine travel sensor motion. If you answer No, then you must specify the direction of travel movement. For quarter‐turn actuators determine rotation by viewing the rotation of the magnet assembly from the back of the instrument (see Travel Sensor Motion on page 71).

Volume booster (indicate if volume booster or quick release valve is present) Tuning set (see Tuning Set in the Detailed Setup section).

Note

Travel Sensor Motion in this instance refers to the motion of the magnet assembly. Note that the magnet assembly may be referred to as a magnetic array in user interface tools.

After completing the setup information, you will be prompted to run auto calibration. 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 Calibration on page 78.

Instruction Manual

D103409X012

If a double‐acting relay is used, you will be prompted to run the relay adjustment when auto calibration is selected. Select Yes to adjust the relay. For additional information refer to Relay Adjustment on page 83.

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.

Performance Tuner

Field Communicator Configure > Guided Setup > Performance Tuner (1‐1‐2)

Note

The Performance Tuner is available for instrument level AD, PD, and ODV.

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.

Instrument Mode

Detailed Setup

December 2013

Field Communicator

Hot Key > Instrument Mode (Hot Key‐1)

Configure > Detailed Setup > Mode and Protection > Instrument Mode (1‐2‐1‐1)

Instrument Mode allows you to either take the instrument Out Of Service or place it In Service. Taking the instrument Out Of Service allows you to perform instrument calibration and also allows you to change setup variables that affect control, provided the calibration/configuration protection is properly set. See Setting Protection.

Note

Some changes that require the instrument to be taken Out Of Service will not take effect until the instrument is placed back In Service or the instrument is restarted.

Control Mode

Field Communicator

Hot Key > Instrument Mode (Hot Key‐2)

Configure > Detailed Setup > Mode and Protection > Instrument Mode (1‐2‐1‐2)

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

Field Communicator Configure > Detailed Setup > Mode and Protection > Restart Control Mode (1‐2‐1‐3)

Restart Control Mode lets you choose which operating mode you want the instrument to be in after a restart. Follow the prompts on the Field Communicator display to define the restart control mode as Resume Last, Analog, or Digital.

Burst Mode

Field Communicator Configure > Detailed Setup > Mode and Protection > 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

Page 56

Detailed Setup

December 2013

Instruction Manual

D103409X012

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.

D Burst Enable—Yes or no. Burst mode must be enabled before you can change the burst mode command.

D Change Burst Enable— Turns Burst Mode on and off. Actual values are Burst Enable = Disabled(Polled), Enabled.

D 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.

D 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.

D Cmd 3 Configured Pressure—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/cm

. Select Cmd 3 Configured Pressure from the

Burst menu to select if the output A, output B, differential (A-B), or supply pressure is sent.

Quaternary variable—travel in % of ranged travel.

Protection

Field Communicator

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 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 calibration.

Auto calibration can be terminated by shorting the auxiliary terminals for one second.

In addition, you can specify Expert tuning and individually set the proportional gain, velocity gain, and minor loop feedback gain. Individually setting or changing any tuning parameter or running the Performance Tuner or Stabilize/Optimize will automatically change the tuning set to X (expert).

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.

Table 4‐4 provides tuning set selection guidelines for Fisher and Baumann 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.

D 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.

D 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.

D Stabilize/Optimize—Stabilize/Optimize permits you to adjust valve response by changing the digital valve controller

tuning. During this routine, the instrument must be out of service; however, the instrument will respond to setpoint changes.

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.

D Performance Tuner

Note

The Performance Tuner is available for instrument level AD, PD, and ODV, and can only be run while in Travel control mode.

The Performance Tuner is used to determine 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

D 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%.

D Integral Limit—The Integral Limit provides an upper limit to the integrator output. The high limit is configurable

from 0 to 100% of the I/P drive signal.

Pressure Tuning

WARNING

D Pressure Tuning Set—There are twelve Pressure Tuning Sets to choose from. Each tuning set provides a preselected

value for the digital valve controller gain settings. Tuning set C provides the slowest response and M provides the fastest response.

Tuning set B is appropriate for controlling a pneumatic positioner. Table 4‐5 lists the proportional gain, pressure integrator gain and minor loop feedback gain values for preselected tuning sets.

In addition, you can specify Expert tuning and individually set the pressure proportional gain, pressure integrator gain, and pressure minor loop feedback gain. Individually setting or changing any tuning parameter will automatically change the tuning set to X (expert).

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.

D Integral Enable—Yes or No. Enable the pressure integral setting to improve static performance by correcting for

error that exists between the pressure target and actual pressure. Pressure Integral Control is disabled by default.

D Integral Gain—Pressure Integral Gain (also called reset) is the gain factor applied to the time integral of the error

signal between desired and actual pressure. Changing this parameter will also change the tuning set to Expert.

Travel/Pressure Control

Field Communicator Configure > Detailed Setup > Response Control > Travel/Pressure Control (1‐2‐2‐2)

D Travel/Pressure Select

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.

Note

Travel / Pressure Select must be set to Travel for double‐acting actuators

Cutoffs and Limits

D 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%.

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%.

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%

D Change Cutoffs—Allows you to set hi and lo cutoffs. When a cutoff is set the corresponding travel or pressure limit

will be disabled.

D 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%

D Travel Limit Lo—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%.

D 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

D 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.

D 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 (Instrument Level ODV)

Note

End Point Pressure Control is available for instrument level ODV.

D 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 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.

D 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.

D103409X012

D Press Set 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.

D Press Sat Time— Pressure Saturation Time is the time the digital valve controller stays in hard cutoff before switching

to pressure control. Default is 45 seconds.

Input Characterization

Field Communicator Configure > Detailed Setup > Response Control > 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.

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

Field Communicator Configure > Detailed Setup > Response Control > Custom Characterization Table (1‐2‐2‐4)

To define a custom input character select Custom Characterization Table from the Response Control menu. Select the point you wish to define (1 to 21), then enter the desired set point value. Press Enter then enter the desired travel target for the corresponding set point. When finished, select point 0 to return to the Response Control menu.

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).

D SP Rate Open—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 9 and 10 this parameter should be set to 0.

D SP Rate Close—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 9 and 10 this parameter should be set to 0.

D Set Point Filter Time (Lag Time)—The 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 9 and 10 this parameter should be set to 0.

Note

Set Point Filter Time (Lag Time) is available for instrument level HC, AD, and PD.

D Lead/Lag Set Point Filter—ODV devices have access to a lead‐lag set point filter that can be used to improve a valve's

dynamic response. The lead‐lag 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.

Note

Lead/Lag is only available for instrument level ODV.

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 4‐6 for typical lead‐lag filter settings.

Lag Time First order time constant. A value of 0.0 will disable the lead‐lag filter. 0.2 sec

The tag you assign is automatically displayed when the Field Communicator establishes contact with the digital valve controller at power‐up.

D Message—Enter any message with up to 32 characters. Message provides the most specific user‐defined means for

identifying individual instruments in multi‐instrument environments.

D Descriptor—Enter a descriptor for the application with up to 16 characters. The descriptor provides a longer

user‐defined electronic label to assist with more specific instrument identification than is available with the HART tag.

D Date—Enter a date with the format MM/DD/YY. Date is a user‐defined variable that provides a place to save the date

of the last revision of configuration or calibration information.

D Valve Serial Number—Enter the serial number for the valve in the application with up to 12 characters.

D Instrument Serial Number—Enter the serial number on the instrument nameplate, up to 12 characters.

D Polling Address—If the digital valve controller is used in point‐to‐point operation, the Polling Address is 0. When

several devices are connected in the same loop, such as for split ranging, each device must be assigned a unique polling address. The Polling Address is set to a value between 0 and 15. To change the polling address the instrument must be Out Of Service.

For the Field Communicator to be able to communicate with a device whose polling address is not 0, it must be configured to automatically search for all or specific connected devices.

Travel Sensor Motion

WARNING

If you answer YES to the prompt for permission to move the valve when determining travel sensor motion, the instrument will move the valve through a significant portion of its travel range. 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.

Select Clockwise/Toward Bottom, or Counterclockwise/Toward Top. Travel Sensor Motion establishes the proper travel sensor rotation. For quarter‐turn actuators determine rotation by viewing the rotation of the magnet assembly from the back of the instrument.

Note

Travel Sensor Motion in this instance refers to the motion of the magnet assembly. Note that the magnet assembly may be referred to as a magnetic array in user interface tools.

D For instruments with Relay A and C: If increasing air pressure at output A causes the magnet assembly to move

down or the rotary shaft to turn clockwise, enter CW/To Bottom Inst. If it causes the magnet assembly to move up, or the rotary shaft to turn counterclockwise, enter CCW/To Top Inst.

Note

Partial Stroke is only available for instrument level ODV.

Follow the prompts on the Field Communicator display to configure the following partial stroke parameters: PST Enable, and View/Edit PST Variables.

PST Enable—Yes or No. Enables or disables the Partial Stroke Test.

PST Vars View/Edit—Follow the prompts on the Field Communicator display to enter or view information for following

PST Variables: Max Travel Movement, Stroke Speed, Pause Time, PST Press Limit, PST Mode Enable, Pressure Set Point, and End Pt Control Enable.

Max Travel Movement—The default value for Max Travel Movement is 10%. It may be set to a value between 1 and 30%

in 0.1% increments.

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.

Pause Time—The Setup Wizard sets the Partial Stroke Pause Time to 5 seconds. This is the pause time between the up and down strokes of the test. It can be set for 5, 10, 15, 20 or 30 seconds.

PST Press Limit (single acting actuators)—During the Setup Wizard, or Auto Calibration, the Partial Stroke Pressure Limit value will be set to a positive value. For single acting actuators that vent from the test starting point, the pressure limit will be a minimum value. For those actuators that fill from the test starting point, the pressure limit will be a maximum value. The pressure signal used for this threshold depends on relay type and is summarized below.

Relay Type Pressure Signal

A or C Port A - Port B B Port B - Port A B Special App. Port B C Special App. Port A

PST Press Limit (double-acting actuators)— During the Setup Wizard or Auto Calibration, the Partial Stroke Pressure Limit value 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 valve for actuators where the Partial Stroke Start Point is the same as the Zero Power Condition.

December 2013

Section 5 Calibration 55

Calibration Overview

When a DVC6200 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 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 then calibrate travel by selecting Configure > Calibrate > Travel Calibration > Auto Calibration. For more detailed calibration information, refer to the following calibration procedures.

Calibrate

Field Communicator Configure > Calibrate (1‐3)

Travel Calibration

D Auto Travel Calibration —This procedure automatically calibrates the travel. The calibration procedure uses the

valve and actuator stops as the 0% and 100% calibration points.

D Manual Travel Calibration —This procedure permits manual calibration of the travel. This calibration procedure

allows you to determine the 0% and 100% calibration points.

Sensor Calibration

D Pressure Sensors—This procedure permits calibrating the three pressure sensors. Normally the sensors are

calibrated at the factory and should not need calibration.

D Analog In Calibration—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.

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 pressure or process fluid, isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the process fluid.

Travel Calibration

Field Communicator Configure > Calibrate > Travel Calibration (1‐3‐1)

If a double‐acting relay is used, you will be prompted to run the relay adjustment when auto or manual calibration is selected. Select Yes to adjust the relay, select No to proceed with calibration. For additional information, refer to Relay Adjustment in this section.

Note

Relay Adjustment is only available for the double‐acting relay (Relay A).

Auto Travel Calibration

1. The auto calibration procedure is automatic. It is completed when the Calibrate menu appears.

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 MLFB sensor.

2. 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.

Table 5‐1. Auto Calibrate Travel Error Messages

Error Message Possible Problem and Remedy

Power failure occurred during Auto Calib

Auto Calib did not complete within the time limit.

Insufficient travel

Drive signal exceed low limit; check supply pressure

Drive signal exceed high limit; check supply pressure

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 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 and checking the magnet array for proper alighment.

1. Check supply pressure (reverse‐acting relay)

2. Friction is too high.

1. Check supply pressure (direct‐acting relay)

2. Friction is too high

Calibration using the Aux Terminal Connections

Note

Pressure range is not captured during this procedure.

Travel calibration can also be accomplished by shorting the auxiliary terminal connections for 3 to 5 seconds. You can abort the procedure by shorting the auxiliary terminals for 1 second.

To enable this calibration Auxiliary Terminal Action must be set to Auto Calibration. The instrument Operational Status during calibration is Calibration in Progress.

Use this calibration procedure to calibrate the digital valve controller travel whenever the I/P converter or relay is replaced. Do not use this calibration for initial calibration when mounting the instrument on an actuator, or if the printed wiring board assembly was replaced.

You can use the auxiliary terminal connections to calibrate the digital valve controller if you suspect calibration has changed due to drift. However, prior to initiating calibration for this reason, perform a Valve Signature diagnostic test, using ValveLink software. This will capture the as‐found data for future root cause analysis.

Partial Stroke Test (ODV only)

Field Communicator Service Tools > Partial Stroke Test (2‐5)

Note

Partial Stroke Test is only available for instrument level ODV.

The Partial Stroke Test allows DVC6200 digital valve controllers with instrument level ODV to perform a Valve Signature type of test while the instrument is in service and operational. In some applications, it is important to be able to exercise and test the valve to verify that it will operate when commanded. This feature allows the user to partially stroke the valve while continually monitoring the input signal. If a demand arises, the test is aborted and the valve moves to its commanded position. The partial stroke valve travel is configurable between 1 and 30% maximum travel, in 0.1% increments. Data from the last partial stroke test is stored in the instrument memory for retrieval by ValveLink software.

The Partial Stroke Test allows you to perform a partial, 10%, stroke test (standard) or a custom stroke test. With the custom stroke test, the stroke may be extended up to 30%. Be sure to check plant guidelines before performing a custom stroke test. The purpose of this test is to ensure that the valve assembly moves upon demand.

A partial stroke test can be initiated when the valve is operating at either 4 or 20 mA (point‐to‐point mode). In applications where a spurious trip is to be minimized, 4 mA is the normal operating position.

When enabled, a partial stroke test may be initiated by the device (as a scheduled, auto partial stroke test), a remote push button located in the field or at the valve, a Field Communicator, or ValveLink software.

Device (Digital Valve Controller)

The Auto Partial Stroke Test allows the partial stroke test to be scheduled by the DVC6200. The test is scheduled in number of hours between tests. Any power cycle will reset the test clock timer.

Auxiliary Terminal

The auxiliary terminal can be used for different applications. The default configuration is for a partial stroke test initiated by shorting the contacts wired to the auxiliary +/- terminals of the DVC6200. Refer to Auxiliary Terminal Wiring Length Guidelines below.

D Local Push Button

A partial stroke test command may be sent to the digital valve controller using a set of contacts wired to the auxiliary +/- terminals. To perform a test, the contacts must be closed for 3 to 5 seconds and then opened. To abort the test, close the contacts for 1 second. The last set of diagnostic data is stored in the instrument memory for later retrieval via ValveLink software.

D Local DI

When configured by the user interface, the Auxiliary Terminal can be used as a discrete input from a pressure switch, temperature switch etc., to provide an alert.

Auxiliary Terminal Wiring Length Guidelines

The Auxiliary Input Terminals of a DVC6200 with instrument level ODV can be used with a locally‐mounted switch for initiating a partial stroke test. Some applications require that the partial stroke test be initiated from a remote location.

The length for wiring connected to the Auxiliary Input Terminals is limited by capacitance. For proper operation of the Auxiliary Input Terminals capacitance should not exceed 18000 pF. As with all control signal wiring, good wiring practices should be observed to minimize adverse effect of electrical noise on the Aux Switch function.

Example Calculation: Capacitance per foot or per meter is required to calculate the length of wire that may be connected to the Aux switch input. The wire should not exceed the capacitance limit of 18000 pF. Typically the wire manufacturer supplies a data sheet which provides all of the electrical properties of the wire. The pertinent parameter is the highest possible capacitance. If shielded wire is used, the appropriate number is the “Conductor to Other Conductor & Shield” value.

Example — 18AWG Unshielded Audio, Control and Instrumentation Cable

Manufacturer's specifications include:

Nom. Capacitance Conductor to Conductor @ 1 KHz: 26 pF/ft Nom. Conductor DC Resistance @ 20 Deg. C: 5.96 Ohms/1000 ft Max. Operating Voltage - UL 200 V RMS (PLTC, CMG),150 V RMS (ITC) Allowable Length with this cable = 18000pF /(26pF/ft) = 692 ft

Example — 18AWG Shielded Audio, Control and Instrumentation Cable

Manufacturer's specifications include:

Nom. Characteristic Impedance: 29 Ohms Nom. Inductance: .15 μH/ft Nom. Capacitance Conductor to Conductor @ 1 KHz: 51 pF/ft Nom. Cap. Cond. to other Cond. & Shield @ 1 KHz 97 pF/ft Allowable Length with this cable = 18000pF /(97pF/ft) = 185 ft

The AUX switch input passes less than 1 mA through the switch contacts, and uses less than 5V, therefore, neither the resistance nor the voltage rating of the cable are critical. Ensure that switch contact corrosion is prevented. It is generally advisable that the switch have gold‐plated or sealed contacts.

Field Communicator

1. Connect the Field Communicator to the LOOP terminals on the digital valve controller.

2. Turn on the Field Communicator.

3. From the Online menu, select Service Tools > Partial Stroke Test.

4. Select either Standard (10%) or Custom. With the Custom Stroke Test, the stroke may be entered up to 30% with configurable stroking speed and pause time.

5. The currently configured Stroke, Stroking Speed, and Pause Time is displayed. Choose “Yes” to run the test using these values. Choose “No” to modify the values. The default value for Stroke Speed is 0.25%/second.

6. The valve begins to move and the actual travel reported by the digital valve controller is displayed on the Field Communicator.

7. Once the valve has reached the endpoint, check that the valve has reached the desired set point. The valve should return to its original position.

For information on configuring the Partial Stroke Test, see Partial Stroke Variables in the Detailed Setup section.
