WARNING
Supply medium must be clean, dry, oil­free, 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, oil­free, 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 Automation Solutions 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 DVC6005 supply input using at least 10 mm (3/8­inch) diameter tubing.
D When using an integral mounted 67CFR filter regulator, lubricate an O­ring 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 1/4­inch socket­head 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
pre­drilled and tapped holes in the actuator yoke. Thread a 1/4­inch socket­head pipe plug into the unused
outlet on the filter regulator. No O­ring 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 1/4­inch socket­head pipe plug into the unused outlet on the filter regulator. No O­ring
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.
