Electrical and Pneumatic Connections

The electrical and pneumatic connections on the digital valve controller are available with the following combinations:
D 1/4 NPT supply and output with 1/2 NPT conduit connections
D G1/4 supply and output with M20 conduit connections
Supply Connections
WARNING
Severe personal injury or property damage may occur from process instability if the instrument air supply is not clean, dry
and oil‐free. 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 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.
CAUTION
Do not use sealing tape on pneumatic connections. This instrument contains small passages that may become obstructed
by detached sealing tape. Thread sealant paste should be used to seal and lubricate pneumatic threaded connections.
Supply pressure medium must be clean, dry air or noncorrosive gas that meets the requirements of ISA Standard
7.0.01 or ISO 8573-1. 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.
A Fisher 67CFR filter regulator with standard 5 micrometer filter, or equivalent, may be used to filter and regulate
supply air. If pressure regulation is not required, a 10 micron in‐line filter may be used.
Connect the nearest suitable supply source to the connection with the arrow pointing towards the opening (see
figure 7).
Electrical Connections
WARNING
Select wiring with temperature rating of > 84_C and/or cable glands that are rated for the environment of use (such as
hazardous area, ingress protection and temperature). Failure to use properly rated wiring and/or cable glands can result in
personal injury or property damage from fire or explosion.
Wiring connections must be in accordance with local, regional, and national codes for any given hazardous area approval.
Failure to follow the local, regional, and national codes could result in personal injury or property damage from fire or
explosion.
The valve may move in an unexpected direction when power is applied to the digital valve controller. To avoid personal
injury and property damage caused by moving parts, keep hands, tools, and other objects away from the valve/actuator
assembly when applying power to the instrument.
