Replacing the PWB Assembly

(KEY 210)
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.
Calibration is required for either Travel
or Pressure Control after PWB
Assembly replacement.
Note that only one calibration is
needed, depending on control
selection.
