Removing the I/P Converter
1. Remove the front cover (key 43), if not already
removed.
2. Refer to figure 7-4. Using a 2.5 mm hex socket
wrench, remove the four socket-head screws (key 23)
that attach the shroud (key 169) and I/P converter
(key 41) to the module base (key 2).
3. Remove the shroud (key 169); then pull the I/P
converter (key 41) straight out of the module base
(key 2). Be careful not to damage the two electrical
leads that come out of the base of the I/P converter.
4. Ensure that the O-ring (key 39) and screen
(key 231) stay in the module base and do not come
out with the I/P converter (key 41).
Replacing the I/P Converter
1. Refer to figure 7-3. Inspect the condition of the
O-ring (key 39) and screen (key 231) in the module
base (key 2). Replace them, if necessary. Apply
silicone lubricant to the O-rings.
2. Ensure the two boots (key 210) shown in figure 7-4
are properly installed on the electrical leads.
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 N
m (14 lbf in).
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 8-2 for key number locations. The PWB
assembly (key 50) is located on the back of the
module base assembly (key 2).
Note
The DVC6200f PWB assembly must be
firmware revision 2.0 or later.
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.
