Installation
December 2009 2-19
Casing-Mounted Regulator
Use the separate 67CFR filter regulator casing
mounting bracket provided with the filter regulator.
Attach the mounting bracket to the 67CFR 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. The O-ring is not required.
Pressure Connections
Pressure connections are shown in figure 2-16. All
pressure connections on the digital valve controller are
1/4 NPT internal connections. Use 10 mm (0.375 inch)
tubing for all pneumatic connections. If remote venting
is required, refer to the vent subsection.
Note
Make pressure connections to the
digital valve controller using tubing
with at least 10 mm (0.375-inch)
diameter.
Supply Connections
WARNING
To avoid personal injury and property
damage resulting from bursting of
parts, do not exceed maximum supply
pressure.
WARNING
Severe personal injury or property
damage may occur from process
instability 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 that 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 proper
amount or method of air filtration or
filter maintenance.
Supply pressure must be clean, dry air that meets the
requirements of ISA Standard 7.0.01. 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.
Alternatively, natural gas may be used as the supply
pressure medium. Gas must be clean, dry, oil-free,
and noncorrosive. H
2
S content should not exceed 20
ppm.
A 67CFR filter regulator with 5 micrometer filter, or
equivalent, may be used to filter and regulate supply
air. A filter regulator can be integrally mounted onto
the side of the digital valve controller, casing mounted
separate from the digital valve controller, or mounted
on the actuator mounting boss. Supply and output
pressure gauges may be supplied on the digital valve
controller. The output pressure gauges can be used as
an aid for calibration.
Connect the nearest suitable supply source to the
1/4 NPT IN connection on the filter regulator (if
furnished) or to the 1/4 NPT SUPPLY connection on
the digital valve controller housing (if a 67CFR filter
regulator is not attached).
Output Connections
A factory mounted digital valve controller has its
output piped to the pneumatic input connection on the
actuator. If mounting the digital valve controller in the
field, or installing the remote-mounted DVC6005f base
unit, connect the 1/4 NPT digital valve controller
output connections to the pneumatic actuator input
connections.
