1. Ensure the module base seal (key 237) is properly installed in the housing (key 1). Ensure the O‐ring (key 12) is in
place on the module base assembly.
2. Connect the terminal box connector to the PWB assembly (key 50). Orientation of the connector is required.
3. Connect the travel sensor connector to the PWB assembly (key 50). Orientation of the connector is required.
4. Insert the module base (key 2) into the housing (key 1).
5. Install three socket head screws (key 38) in the module base into the housing. If not already installed, press three
retaining rings (key 154) into the module base. Evenly tighten the screws in a crisscross pattern to a final torque of
16 NSm (138 lbfSin).
CAUTION
Personal injury, property damage, or disruption of process control can result if the cable assemblies/wiring are damaged
when attaching the cover to the module base assembly
Ensure that the cable assemblies/wiring are positioned in the cavity of the module base so they do not get compressed or
damaged when attaching the cover to the module base assembly in step 6.
6. Attach the cover (key 43) to the module base assembly.

Submodule Maintenance

The digital valve controller's module base contains the following submodules: I/P converter, PWB assembly, and
pneumatic relay. If problems occur, these submodules may be removed from the module base and replaced with new
submodules. After replacing a submodule, the module base may be put back into service.
CAUTION
Exercise care when performing maintenance on the module base. Reinstall the cover to protect the I/P converter and
gauges when servicing other submodules.
In order to maintain accuracy specifications, do not strike or drop the I/P converter during submodule maintenance.

I/P Converter

Refer to figure 8‐2 or 8‐4 for key number locations. The I/P converter (key 41) is located on the front of the module
base.
Note
After I/P converter submodule replacement, calibrate the digital valve controller to maintain accuracy specifications.
Replacing the I/P Filter
A screen in the supply port beneath the I/P converter serves as a secondary filter for the supply medium. To replace this
filter, perform the following procedure:
