Note
To avoid affecting performance of the instrument, inspect the guide surface on the module and the corresponding seating area in
the housing before installing the module base assembly. These surfaces must be free of dust, dirt, scratches, and contamination.
Ensure the module base seal is in good condition. Do not reuse a damaged or worn seal.
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).
Note
For stainless steel digital valve controllers pipe thread sealant (key 64) is recommended under the head of the three socket head
screws (key 38) prior to attaching the module base to the housing in the next step.
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).
