Using this Guide
This guide describes how to install the digital valve controller and setup and calibrate using the local operator interface. The interface consists of a liquid crystal display, four pushbuttons, and a switch for position transmitter configuration. The DVC2000 is supplied with one of three different language packs preinstalled, depending on the firmware revision and ordering option. Language pack options are shown in table 1 on page 19. To configure the language, follow the procedure outlined in the Basic Setup section. The instrument must be powered with at least 8.5 volts and 3.5 mA to operate the local interface. Certain procedures require up to 20 mA of current.
You can also setup and calibrate the instrument using a Field Communicator such as the AMS Trex Communicator, a personal computer with ValveLink
™
software, or AMS Suite: Intelligent Device Manager. For
™
Device
information on using the software with a FIELDVUE instrument, refer to the appropriate user guide or help.
Maintenance procedures for replaceable components are included on page 29.
Do not install, operate, or maintain a DVC2000 digital valve controller without being fully trained and qualified in valve, actuator, and accessory installation, operation, and maintenance. To avoid personal
injury or property damage, it is important to carefully read, understand, and follow all contents of this quick start guide, including all safety cautions and warnings. Refer to the appropriate supplement listed

Note
The DVC2000 is not designed to correct for significant stem rotation on sliding stem actuators.
WARNING
Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before mounting the DVC2000 digital valve controller:
D Always wear protective clothing, gloves, and eyewear when performing any installation procedures.
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 control valve.
D Use bypass valves or completely shut off the process to isolate the control valve from process pressure. Relieve process
pressure from both sides of the control valve.

WARNING
This product is intended for a specific range of application specifications, found in the Specifications table on page 31. Incorrect configuration and use of a positioning instrument could result in the malfunction of the product, property damage or personal injury.
CAUTION
Do not use sealing tape on pneumatic connections. This instrument contains small passages that may become obstructed by detached sealing tape. Thread sealant paste should be used to seal and lubricate pneumatic threaded connections.
Note
Refer to the appropriate Hazardous Area Approvals and Special Instructions for “Safe Use" and Installations in Hazardous Locations supplement for approval specific safe use and installation information (see page 4).
Valve / Actuator Mounting
If ordered as a part of a control valve assembly, the factory will mount the digital valve controller on the actuator and calibrate 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. The following procedures are general guidelines you should consider when mounting the digital valve controller. See the instructions that come with the mounting kit for detailed information on mounting the digital valve controller to a specific actuator model.

CAPTIVE MOUNTING BOLTS, M8
The feedback system for the DVC2000 digital valve controller utilizes a magnetic field 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.
CAUTION
The magnet 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.
Use of Magnetic Tools with the DVC2000
D Magnetic Tip Screw Drivers – Magnetic tip screw drivers should not be brought in close proximity to the DVC2000 or the
magnetic 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 DVC2000.
– These are high power magnets used to hold 4-20 ma calibrators.

D103203X012
June 2020
Note
As a general rule, do not use less than 50% of the magnet assembly 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 DVC2000 housing) has to remain within this range throughout the entire valve travel. See figure 2.
The linear magnet assemblies are symmetrical. Either end may be up.
There are a variety of mounting brackets and kits that are used to mount the DVC2000 to different actuators. However, despite subtle differences in fasteners, brackets, and connecting linkages, the procedures for mounting can be categorized as follows:
D Air‐to‐open sliding‐stem (linear) actuators
D Air‐to‐close sliding‐stem (linear) actuators
D Air‐to‐open 667 size 30i - 76i or Fisher GX actuator
D Air‐to‐close 657 size 30i - 70i or GX actuator
D Rotary actuators with travel up to 90 degrees
See figure 3 for the different travel feedback magnet assemblies.

Sliding-Stem (Linear) 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 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.
3. Loosely attach the feedback pieces and magnet assembly to the valve stem connector. Do not tighten the fasteners because fine adjustment is required.
CAUTION
Do not install a magnet assembly that is shorter than the physical travel of the actuator. Loss of control will result from the magnet assembly moving outside the range of the index mark in the feedback slot of the DVC2000 housing.
4. Using the alignment template (supplied with the mounting kit), position the magnet assembly inside the retaining slot.
5. Align the magnet assembly as follows:
D For air‐to‐open actuators (e.g. Fisher 667) vertically align the magnet assembly so that the center line of the
alignment template is lined up as close as possible with the upper
extreme of the valid travel range on the
magnet assembly. See figure 4.
D For air‐to‐close actuators (e.g. Fisher 657) vertically align the magnet assembly so that the center line of the
alignment template is lined up as close as possible with the lower
extreme of the valid travel range on the
magnet assembly. See figure 5.

Integral Mounted Fisher Actuators
The DVC2000 digital valve controller mounts directly on the 657 size 30i - 70i, 667 size 30i - 76i, and the GX actuator without the need for a mounting bracket.
However, in applications where the process temperature exceeds 80_C (176_F), it may be necessary to apply an insulating gasket between the actuator yoke of the GX and the DVC2000, as shown in figure 8. The heat conducted from the process line will transmit through the valve body and actuator and ultimately to the DVC2000. Temperature seen at the DVC2000 is a function of the ambient temperature as well as the process temperature. Guidelines on when to apply the high temperature gasket set are shown in figure 9.

Electrical and Pneumatic Connections
The electrical and pneumatic connections on the digital valve controller are available with the following combinations:
D 1/4 NPT supply and output with 1/2 NPT conduit connections
D G1/4 supply and output with M20 conduit connections
Supply Connections
WARNING
Severe personal injury or property damage may occur from process instability if the instrument air supply is not clean, dry and oil‐free. While use and regular maintenance of a filter that removes particles larger that 40 micrometers in diameter will suffice in most applications, check with an Emerson field office and industry instrument air quality standards for use with corrosive air or if you are unsure about the proper amount or method of air filtration or filter maintenance.
CAUTION
Do not use sealing tape on pneumatic connections. This instrument contains small passages that may become obstructed by detached sealing tape. Thread sealant paste should be used to seal and lubricate pneumatic threaded connections.
Supply pressure medium must be clean, dry air or noncorrosive gas that meets the requirements of ISA Standard
7.0.01 or ISO 8573-1. A maximum 40 micrometer particle size in the air system is acceptable. Further filtration down
to 5 micrometer particle size is recommended. Lubricant content is not to exceed 1 ppm weight (w/w) or volume (v/v) basis. Condensation in the air supply should be minimized.
A Fisher 67CFR filter regulator with standard 5 micrometer filter, or equivalent, may be used to filter and regulate supply air. If pressure regulation is not required, a 10 micron in‐line filter may be used.
Connect the nearest suitable supply source to the connection with the arrow pointing towards the opening (see figure 7).
Electrical Connections
WARNING
Select wiring with temperature rating of > 84C 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 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.

The digital valve controller is normally powered by a control system output card. The use of shielded cable will ensure proper operation in electrically noisy environments. Wire size requirements are 14 AWG maximum, 26 AWG minimum.
Be sure to follow the appropriate I.S. circuit guidelines when installing field wiring to the loop terminals as well as the limit switch and transmitter terminals.
Wire the digital valve controller as follows:
1. Remove the main instrument cover.
2. Route the field wiring into the terminal box through the conduit connection. When applicable, install conduit using local and national electrical codes that apply to the application.
3. Connect the control system output card positive wire “current output” to the +11 terminal. Connect the control system output card negative (or return) wire “current output” to the -12 terminal.
4. Two ground terminals are available for connecting a safety ground, earth ground, or drain wire. These ground terminals are electrically identical. Make connections to these terminals following national and local codes and plant standards.
5. Replace the cover if the local interface is not being used for configuration or calibration.
Options Boards
All three options circuits (transmitter, switch 1 and switch 2) control current from an external power source similar to the operation of a 2‐wire transmitter.
Limit Switches
On units that are supplied with integral limit switches, additional terminals provide the field wiring connection point. The limit switches are isolated from each other and from the digital valve controller's primary feedback. If only one switch is to be used, you must use channel 1. Although electrically isolated per Intrinsic Safety requirements, channel 2 derives its power from channel 1. Therefore channel 2 cannot be used alone.
Wire the limit switches as follows:
1. Remove the main instrument cover.
2. Route the field wiring into the terminal box through the conduit connection. When applicable, install conduit using local and national electrical codes that apply to the application.
3. Connect the control system input card positive wire “switch input” to the +41 terminal. Connect the control system input card negative wire “switch input” to the -42 terminal. Refer to figure 15.

Position Transmitter
On units that are supplied with an integral valve position transmitter, additional terminals provide the field wiring connection point. The position transmitter circuit in the DVC2000 derives its operating power from the 4‐20 mA control system input in the same manner as a 2‐wire transmitter. In addition, the transmitter function gets position information (through an opto‐isolator) from the digital valve controller so the 4‐20 mA position control loop must also be powered in order for the position transmitter to provide an output representing the valve position.
Note
In an Intrinsically Safe installation with the options in use, the wire pairs must be shielded. Additionally, to prevent cross‐wiring, the individual wires must not be exposed beyond the terminal barrier walls.
Wire the position transmitter as follows:
1. Remove the main instrument cover.
2. Route the field wiring into the terminal box through the conduit connection. When applicable, install conduit using local and national electrical codes that apply to the application.
3. Connect the control system input card positive wire “current input” to the +31 terminal. Connect the control system input card negative wire “current input” to the -32 terminal. Refer to figure 15.
4. Replace the cover if the local interface is not being used for configuration or calibration.
Vent
By design, the instrument exhausts supply air into the area under the cover. The vent should be left open to prevent pressure buildup under the cover and to drain any moisture that may accumulate in the housing. The control valve assembly should be installed so that the primary vent provides gravitational draining.
If a remote vent is required, the vent line must be as short as possible with a minimum number of bends and elbows.
Communications Connections
A HART communicating device, such as a Field Communicator or a personal computer running ValveLink software communicating through a HART modem, interfaces with the DVC2000 digital valve controller. You can connect at any point on the 4‐20 mA loop. Alternatively, convenient termination points are located on the termination board (figure
15). The instrument must be powered before digital communication will commence.

Basic Setup and Calibration
The local operator interface is available on all DVC2000 digital valve controllers. The interface consists of a liquid crystal display, four pushbuttons, and a switch for position transmitter configuration. The DVC2000 is supplied with one of three different language packs preinstalled, depending on the firmware revision and ordering option. Language pack options are shown in table 1. To configure the language, follow the procedure outlined in the Basic Setup section. The instrument must be powered with at least 8.5 volts and 3.5 mA to operate the local interface. Certain procedures require up to 20 mA of current.
CAUTION
When accessing the terminals or pushbuttons, proper means of electrostatic discharge protection is required. Failure to provide appropriate protection can cause the valve to move, resulting in valve/actuator instability.
Status Information
The first (home) screen on the LCD that is displayed after applying power to the instrument contains basic status information. On an instrument that is calibrated and operating properly, the flow chart in figure 16 shows the available information by pressing the right (") arrow key.

Basic Setup
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.
When the DVC2000 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 and powered electrically and pneumatically.
Selecting the Language
The DVC2000 is supplied with one of three different language packs preinstalled, depending on the firmware revision and the ordering option. See table 1 for language pack options.

Automatic tuning will provide status information as the procedure is running. Manual tuning will require you to choose from one of eleven tuning sets. 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. Table 3 lists the proportional gain, velocity gain, and minor loop feedback gain values for preselected tuning sets. Manual tuning is only recommended when the automatic tuning procedure results in failure.

A typical starting point for most small actuators is “C”. Using the UP (Y) and DOWN (B) arrow keys will apply the values immediately. You can then change the input current to observe the response. When you are satisfied with the response, press the RIGHT (") arrow key to fine tune the instrument. The UP (Y) and DOWN (B) arrow keys will apply more or less damping to fine tune the overshoot after a step input change.
After manual tuning is complete, you will have the choice to save the tuning data or exit the procedure without saving. If you exit without saving, the last saved tuning data will be restored.
Detailed Setup
If the factory default configuration values need to be changed, the DETAILED SETUP procedure provides access. See figure 20 for the flowchart showing the sequence of screens. To access this procedure from the home screen, press the DOWN (B) arrow key four times. The RIGHT (") arrow key brings you into the configuration items. Once you are in a particular configuration item, use the UP (Y) and DOWN (B) arrow keys to select the appropriate choice.
To exit this procedure, press the RIGHT (") arrow key and view the remaining configuration items until you reach the exit screen. If you exit without saving, the last saved configuration data will be restored.
Below is an explanation of the configuration items.
Zero Control Signal—Identifies whether the valve is fully OPEN or fully CLOSED when the input is 0%. If you are unsure how to set this parameter, disconnect the current source to the instrument. The resulting valve travel is the Zero Control Signal. This corresponds to setting the output pressure to zero.
Pressure Units—Defines the pressure units in either PSI, BAR, or KPA.
Input Range Low—This will correspond to 0% travel if the Zero Control Signal is configured as closed. If the Zero Control
Signal is configured as open, this will correspond to 100% travel.
Input Range High—This will correspond to 100% travel if the Zero Control Signal is configured as closed. If the Zero Control Signal is configured as open, this will correspond to 0% travel.
Characteristic—Defines the relationship between the travel target and the ranged set point. Ranged set point is the input to the characterization function. If the Zero Control Signal is closed, then a set point of 0% corresponds to a ranged input of 0%. If the Zero Control Signal is open, a set point of 0% corresponds to a ranged input of 100%. Travel target is the output from the characterization function.
Note
Travel cutoffs are enabled by default on all units.

The factory default characteristic is LINEAR. You can also use a QUICK OPEN, EQUAL %, or CUSTOM function. However, the custom function is initially configured linear, unless you use a HART based host to reconfigure the custom points. Custom configuration can be selected, but the curve cannot be modified with the local interface.

Switch #1 Trip Point—Defines the threshold for the limit switch wired to terminals +41 and -42 in percent of calibrated travel.
Switch #1 Closed—Configures the action of the limit switch wired to terminals +41 and -42. Selecting ABOVE configures the switch to be closed when the travel is above the trip point. Selecting BELOW configures the switch to be closed when the travel is below the trip point. Selecting DISABLED removes the icons and status from the display.
Switch #2 Trip Point—Defines the threshold for the limit switch wired to terminals +51 and -52 in percent of calibrated travel.
Switch #2 Closed—Configures the action of the limit switch wired to terminals +51 and -52. Selecting ABOVE configures the switch to be closed when the travel is above the trip point. Selecting BELOW configures the switch to be closed when the travel is below the trip point. Selecting DISABLED removes the icons and status from the display.
Note
Switch #2 is only operational if power is applied to switch #1 also. Switch #2 cannot be used alone.
Position Transmitter Calibration
Note
This procedure will not move the control valve. The instrument will simulate an output for calibration purposes only.
This procedure is only available on units that have the optional position transmitter hardware installed. The DVC2000 digital valve controller is shipped from the factory with the position transmitter already calibrated. You do not normally need to perform this procedure. However, if you suspect that this needs adjustment, follow the procedure below and refer to figure 22.

Diagnostic Messages, Codes and Details
The DVC2000 digital valve controller is constantly diagnosing itself for abnormal conditions while powered‐up. The following messages will appear on the local user interface if a fault condition exists (identified on the default screen by
!
the alert symbol
).
SWITCH 1 ??? SWITCH 2 ???—The alert symbol in conjunction with the above text indicates that limit switch circuit 1 is not powered,
or at least one of the switches is enabled. In order for either of the switches to work, switch circuit 1 must be powered. Switch 2 cannot be used alone. To eliminate the alert symbol, you can either apply 5 to 30 VDC to switch circuit 1 or disable both switches from DETAILED SETUP.
27
June 2020
Quick Start Guide
D103203X012
Once switch circuit 1 is powered properly, question marks (???) will indicate that the corresponding switch is disabled.
Shutdown Activated— This screen appears if the positioner has shut down and no air is being delivered to the actuator. Therefore, the valve is at its fail‐safe position. An example of a source of this error is corrupt firmware code upon start‐up. The factory default setting for this error is disabled. Therefore, this alert will only be enabled by actively configuring it with a HART based host (e.g. Field Communicator, ValveLink Software).
Travel Deviation— This error message indicates that there is a difference between the input signal (after characterization) and the actuator travel reading from the position feedback element. The default setting is 7% for 5 seconds. These settings can be configured through a HART communicating host on any instrument HC tier or higher. Possible sources of this error are insufficient air supply or excessive valve friction.
Replace Main Board— A problem with the electronics has been detected. Sources of this error may include hardware or firmware problems. If this error is detected, the instrument may be operational, but performance will be degraded.
Check Mounting— The valve position feedback reading is valid, but it is outside the operating range. Sources of this error include loose or bent mounting brackets or a misaligned magnet assembly. This error does not identify faulty components, but rather faulty installation or alignment. This alert is also called a Travel Sensor Failure.
Check Supply— The valve is not able to reach its target position due to insufficient supply pressure. This error will most likely occur in conjunction with the Travel Deviation error.
Check I/P Converter— A problem relating to the I/P converter has been detected. Sources of this error include:
D Electronics problems indicated by the drive current read back being out of range
D Low supply pressure indicated by an active drive signal alert
D A stuck valve resulting in integrator wind‐up.
Device Locked by HART— Another HART host (e.g. ValveLink software, AMS Suite: Intelligent Device Manager, or the Field Communicator) is communicating with the DVC2000. Typically this means that the instrument is “out of service”. In devices with firmware version 3 or later, you can clear this message by holding down the left button while cycling power to the DVC2000. This will place the instrument back “in service.”
FIELDVUE Instruments—This is displayed when there are no languages loaded on the DVC2000. This could occur during firmware download.
Pressure = ???—The actuator pressure reading is greater than 125% of the configured maximum supply pressure. For example, if the supply pressure range was set to 35 psi and the actual supply pressure was 45 psi, you will see ???'s when the DVC2000 is delivering full supply pressure to the actuator. If you reduce the supply pressure, or stroke the valve closed (air‐to‐open/fail closed setup), eventually there will be a point where numerical values appear.
This configuration parameter can be changed through the Field Communicator (1‐1‐2‐2‐3) or ValveLink software (Detailed Setup > Pressure).
