(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-322 Main Board

Assembly.

(6) Reassemble the module.

(7) Test your scanner to enusre proper operation.

5.1.6 Replacement of O-Rings

MEAS calibration valves include static and dynamic O-ring seals. When used properly, the

rated durability of the dynamic O-rings is in excess of 1,000,000 shifts of the calibration valve.

The procedures described below should be used for replacement of all the O-rings in the Model

9116 Intelligent Pressure Scanner. Use the tools and follow the general warnings already

described at the start of Section 5.1.

The material needed for the O-ring replacement can be acquired through the proper

maintenance kit available from MEAS. Specifically needed for these procedures are calibration

manifold and piston O-rings, PTFE cup seals, a fast evaporating cleaning fluid ( i.e. acetone,

alcohol, Freon

, etc.), 50 psi dry air supply, and Krytox

fluorinated grease (read product

warnings and recommendations thoroughly). Service of O-ring seals requires a clean

working environment. Introduction of contaminants to the O-ring or internal calibration

manifold surfaces can result in internal pneumatic leaks. Inspection for contaminates generally

requires some type of magnification device, such as a microscope.
