Air‐to‐Open GX Actuators 6. The pneumatic output port on the DVC6215 lines up with the integral GX actuator pneumatic port. See figure 2‐16. 7. Using a 5 mm hex wrench, attach the feedback unit to the GX actuator mounting pad on the side that has the open pneumatic port. Be sure to place the O‐ring between the feedback units pneumatic output and the actuator mounting pad. Pneumatic tubing between the feedback unit and the actuator is not required because the air passages are internal to the actuator. 8. Connect the pneumatic tubing from the DVC6205 to the feedback units pneumatic port provided on the front of the DVC6215 as shown in figure 2‐16. Figure 2‐16.

9. Check for clearance between the magnet assembly and the DVC6215 feedback slot. 10. If not already installed, install a vent in the port on the upper diaphragm casing's air supply connection on the actuator yoke leg.
Air‐to‐Close GX Actuators 6. Using a 5 mm hex wrench, attach the feedback unit to the GX actuator mounting pad. 7. Check for clearance between the magnet assembly and the DVC6215 feedback slot. 8. Install tubing between the actuator casing and the appropriate DVC6215 pneumatic output port. 9. If not already installed, install a vent in the port on the lower diaphragm casing.
Note D To convert to air-to-open, install an O‐ring between the feedback units pneumatic output and the actuator mounting pad. Connect pneumatic tubing from the DVC6205 to the DVC6215. Refer to figure 2‐16. D To convert to air-to-close, remove the O‐ring between the feedback units pneumatic output and the actuator mounting pad. Disconnect the pneumatic tubing from the DVC6205 to the DVC6215. Install tubing between the pneumatic output connection of the DVC6205 to the pneumatic port on top of the actuator casing.
