Supply Connections

Personal injury or property damage
may occur from an uncontrolled pro-
cess if the supply medium is not
clean, dry, oil-free, or noncorrosive
gas. Industry instrument air quality
standards describe acceptable dirt,
oil, and moisture content. Due to the
variability in nature of the problems
these influences can have on pneu-
matic equipment, Fisher Controls has
no technical basis to recommend the
level of filtration equipment required
to prevent performance degradation
of pneumatic equipment. A filter or
filter regulator capable of removing
particles 40 microns in diameter
should suffice for most applications.
Use of suitable filtration equipment
and the establishment of a mainte-
nance cycle to monitor its operation
is recommended.

DVC5000 SERIES WITH INTEGRAL
MOUNTED 67CFR FILTER/REGULATOR
Supply pressure must be clean, dry air or noncorrosive
gas that meets the requirements of ISA Standard
S7.3. A Type 67CFR filter regulator, or equivalent,
may be used to filter and regulate supply air.
If you are using a Type 67CFR filter regulator, connect
the supply line to the1/4-inch NPT IN connection and
attach tubing from the output connection on the filter
regulator to the SUPPLY connection on the
instrument. If you are using an integral mounted Type
67CFR filter regulator, connect the supply to the IN
connection on the regulator.
Output Connection
A factory mounted digital valve controller has its
output piped to the supply connection on the actuator.
If mounting the digital valve controller in the field,
connect the 1/4-inch NPT digital valve controller output
connection to the pneumatic actuator input connection.
If using the Type DVC5010 on actuators with greater
than 2-inch travel, plug the output connection on the
side of the digital valve controller and use the output
connection on the back of the unit.
