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.

(5) Attach the wiring harness to the solenoid and connector P6 of the PC-280 CPU board.

(6) Reassemble the module.

(7) Test your scanner to ensure proper operation.
