DVC2000 Digital Valve Controller

April 2014

Air‐to‐Close GX Actuators

6. Remove the cover of the digital valve controller.

7. Using a 6 mm hex wrench, attach the digital valve controller to the GX actuator mounting pad.

Note

The O‐ring and G1/4 or 1/4 NPT plugs (supplied in the mounting kit) are not used with this actuator construction.

8. Check for clearance between the magnet assembly and the DVC2000 feedback slot. The magnet assembly should

be positioned so that the index mark on the pole pieces (back of the positioner housing) is within the valid range on

the magnet assembly throughout the range of travel. See figure 2.

9. Install tubing between the actuator casing and the pneumatic positioner output connection that has the arrow

pointing away from the opening. See figure 7.

10. Install a vent in the port on the lower diaphragm casing.

Note

When field converting a GX actuator from fail‐open to fail‐closed (or vice‐versa), you will need to change the plugs for the

pneumatic passages in the DVC2000 housing.

To convert to fail‐closed, remove the R1/8 pneumatic plug on the back of the DVC2000 housing and install an O‐ring. Plug

the external pneumatic output with a 1/4 NPT or G1/4 plug (depending on the housing version). Refer to figure 12.

To convert to fail‐open, remove the external pneumatic plug (1/4 NPT or G1/4 plug depending on the housing version).

Install an R1/8 plug on the back of the DVC2000 housing. Install tubing between the pneumatic output connection of the

DVC2000 to the pneumatic port on top of the actuator casing.
