(5) Replace the PC-206 board as described in Section 5.1.3.1 and reassemble the module.
Ensure that the two hex-head standoff screws are installed on DH200 positions 2 and 15
and that they align with the two PC-206 mounting holes.
(6) Test your scanner to ensure proper operation.
5.1.5 Calibration Valve Solenoid Replacement
Following is a step-by-step procedure to replace the Calibration Valve Solenoids in a Model
9016 Intelligent Pressure Scanner. All Model 9016 scanners contain the purge and leak check
calibration manifold and contain two solenoid valves. Use the tools and follow the general
warnings already described at the start of Section 5.1.1. Refer to Section 5.1.6.5 for details
concerning solenoid O-ring replacement.
(1) Disassemble the module as described in Section 5.1.2.
(2) Carefully remove the two (2) Phillips-head screws from the top of the solenoid.
Disconnect the solenoid from connector P6 of the PC-280 CPU board. See Figure 5.5.
(3) If the either the new or old solenoid does not have a pluggable wiring harness at the
solenoid, the new solenoid wires will require crimp pins to be installed for insertion in the
P6 mating housing. The proper crimp pin is Molex part number 08-56-0110. After
installing the crimp pins to the solenoid wiring, remove the old crimp pins from the
Molex P6 housing and insert the new solenoid's wiring. Ensure that the new wires are
installed in the same position as the old wires.
(4) Ensure the three (3) solenoid manifold O-rings are present and free of contaminants.
Replace the solenoid with the new one by carefully aligning and gently tightening the
screws.
