3. Install the I/P converter (key 41) straight into the module base (key 2), taking care that the two electrical leads feed
into the guides in the module base. These guides route the leads to the printed wiring board assembly submodule.
4. Install the shroud (key 169) over the I/P converter (key 41).
5. Install the four socket‐head screws (key 23) and evenly tighten them in a crisscross pattern to a final torque of 1.6
NSm (14 lbfSin).
6. After replacing the I/P converter, calibrate travel or perform touch‐up calibration to maintain accuracy
specifications.

Printed Wiring Board (PWB) Assembly

Refer to figure 7‐2 or 7‐4 for key number locations. The PWB assembly (key 50) is located on the back of the module
base assembly (key 2).
Note
If the PWB assembly submodule is replaced, calibrate and configure the digital valve controller to maintain accuracy specifications.
Removing the Printed Wiring Board Assembly
1. Separate the module base from the housing by performing the Removing the Module Base procedure.
2. Remove three screws (key 33).
3. Lift the PWB assembly (key 50) straight out of the module base (key 2).
4. Ensure that the O‐rings (key 40) remain in the pressure sensor bosses on the module base assembly (key 2) after the
PWB assembly (key 50) has been removed.
Replacing the Printed Wiring Board Assembly
1. Apply silicone lubricant to the pressure sensor O‐rings (key 40) and install them on the pressure sensor bosses in the
module base assembly.
2. Properly orient the PWB assembly (key 50) as you install it into the module base. The two electrical leads from the
I/P converter (key 41) must guide into their receptacles in the PWB assembly and the pressure sensor bosses on the
module base must fit into their receptacles in the PWB assembly.
3. Push the PWB assembly (key 50) into its cavity in the module base.
4. Install and tighten three screws (key 33) to a torque of 1 NSm (10.1 lbfSin).
5. Reassemble the module base to the housing by performing the Replacing the Module Base procedure.
6. Setup and calibrate the digital valve controller.
Note
Calibration is required for either Travel or Pressure Control after PWB Assembly replacement.
Note that only one calibration is needed, depending on control selection.
