(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
Pressure Systems’ 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 Pressure Systems. Specifically needed for these procedures are
calibration manifold and piston O-rings, Teflon 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
.
