Use of 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. 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, a personal computer with ValveLink software or AMS Suite: Intelligent Device Manager. For information on using the software with a FIELDVUE instrument, refer to the appropriate user guide or help.

Additional information for installing, operating, and maintaining the DVC2000 digital valve controller can be found in the related documents listed on page 32.

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 Hazardous Area Approvals and Special Instructions for “Safe Use” and Installations in

Hazardous Locations, on page 33, for approval specific safe use information. If you have any questions about these instructions, contact your Emerson Process Management sales office before proceeding.

Installation

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.

D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.

D Check with your process or safety engineer for any additional measures that must be taken to protect against process

media.

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.

WARNING

This product is intended for a specific range of application specifications, found in the Specifications table on page 29. Incorrect configuration of a positioning instrument could result in the malfunction of the product, property damage or personal injury.

Note

Refer to Hazardous Area Approvals and Special Instructions for “Safe Use" and Installations in Hazardous Locations, on page 33, for approval specific safe use and installation information.

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 arrays.

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 DVC2000

D Magnetic Tip Screw Drivers – Magnetic tip screw drivers should not be brought in close proximity to the DVC2000 or the

magnetic feedback array (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.

Note

As a general rule, do not use less than 50% of the magnet array for full travel measurement. Performance will decrease as the array is increasingly subranged.

The linear magnet arrays 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 arrays 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 Fisher GX actuator

D Air‐to‐close GX actuator

D Rotary actuators with travel up to 90 degrees

See figure 3 for the different travel feedback magnet pieces.

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 array that is shorter than the physical travel of the actuator. Loss of control will result from the magnet array 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 feedback array inside the retaining slot.

5. Align the magnet array as follows:

D For air‐to‐open actuators (e.g. Fisher 667) vertically align the magnet array 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

feedback array. See figure 4.

D For air‐to‐close actuators (e.g. Fisher 657) vertically align the magnet array 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

feedback array. See figure 5.

6. Tighten the fasteners and remove the alignment template.

Note

Use a flat end hex key to tighten the mounting assembly fasteners to a torque of 2.37 N•m (21 in•lbf) for 4 mm screws, and

5.08 N•m (45 in•lbf) for 5 mm screws. While tightening the fasteners using the hex key should be sufficient, blue (medium) thread locker may be used for additional security.

7. Mount the digital valve controller to the mounting bracket, using the mounting bolts. See figure 6.

8. Check for clearance between the magnet assembly and the DVC2000 feedback slot. The magnet assembly should be positioned so that the index mark in the feedback slot of the DVC2000 housing is within the valid range on the magnet assembly throughout the range of travel. See figure 2.

9. Install tubing between the actuator casing and the pneumatic positioner output connection that has the arrow pointing away from the opening. See figure 7.

Mounting on GX Actuators

The DVC2000 digital valve controller mounts directly on 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 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.
