Before You Begin
Do not install, operate, or maintain a DVC6200 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 43, for approval specific safe use information. If you have any questions about these
instructions, contact your Emerson Process Management sales office before proceeding.
WARNING
Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before proceeding
with any Installation procedures:
D Always wear protective clothing, gloves, and eyewear to prevent personal injury or property damage.
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 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
To avoid static discharge from the plastic cover when flammable gases or dust are present, do not rub or clean the cover
with solvents. To do so could result in a spark that may cause the flammable gases or dust to explode, resulting in personal
injury or property damage. Clean with a mild detergent and water only.

General Mounting Guidelines
If ordered as 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. The
following procedures are general guidelines. See the instructions that come with the mounting kit for detailed
information on mounting the digital valve controller to a specific actuator model.
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.
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 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 – These are high power magnets used to hold 4-20 mA calibrators. 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
D The mounting instructions also apply to the DVC6215 remote mount feedback unit.
D 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.
D The linear magnet assemblies have a valid travel range indicated by arrows molded into the piece. This means that the hall
sensor (the center point of the channel on the back of the DVC6200 housing) has to remain within this range throughout the
entire valve travel. The linear magnet assemblies are symmetrical. Either end may be up.
D The magnet assembly may be referred to as a magnetic array in user interface tools.
D Mounting the instrument vertically, with the vent at the bottom of the assembly, or horizontally, with the vent pointing down, is
recommended to allow drainage of moisture that may be introduced via the instrument air supply.

WARNING
Supply medium must be clean, dry, oilfree, and noncorrosive and meet the requirements of ISA Standard 7.0.01 or
ISO 8573-1.
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, 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.
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.
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.
D Ensure that all caps and covers are correctly installed before putting this unit back into service. Failure to do so could
result in personal injury or property damage from fire or explosion.
2. Connect a filter or filter regulator to the DVC6200 supply input using at least 10 mm (3/8inch) diameter tubing.
D When using an integral mounted 67CFR filter regulator, lubricate an Oring and insert it in the recess around the
SUPPLY connection on the digital valve controller. Attach the filter regulator to the side of the digital valve
controller. Thread a 1/4inch sockethead pipe plug into the unused outlet on the filter regulator. This is the
standard method of mounting the filter regulator. No tubing is required.
D When using a yoke mounted 67CFR filter regulator, mount the filter regulator with two cap screws to the
predrilled and tapped holes in the actuator yoke. Thread a 1/4inch sockethead pipe plug into the unused
outlet on the filter regulator. No Oring is required.
D When using a casing mounted filter regulator, use a separate casing mounting bracket (typically provided with
the filter regulator). Attach the mounting bracket to the filter regulator and then attach this assembly to the
actuator casing. Thread a 1/4inch sockethead pipe plug into the unused outlet on the filter regulator. No Oring
is required.
D If the supply pressure is less than the maximum actuator and instrument pressure rating, a regulator is not
required. However, a filter is always required. Attach the filter securely to the actuator or instrument.
