5.1.1 Common Maintenance
The NetScanner
™ System Intelligent Pressure Scanners are designed for rugged use. No
special preventive maintenance is required, although periodic maintenance may be required to
replace worn or damaged components. Upgrades or modifications of module hardware or
firmware may also be periodically required. For users who wish to do their own maintenance
and repair, maintenance kits and replacement parts may be purchased from the factory.
When performing any type of maintenance of NetScanner
™ System
components, the following guidelines and precautions should
always be followed :
● Verify that the work area and technicians are properly
grounded to prevent damage to electronic components due to
electrostatic
discharge.
● Ensure that all electrical and pneumatic connections have
been removed from the module.
● Ensure that the work area is free of dust and other possible
contaminants that may affect the high tolerance machined
parts (and pneumatic seals, if model has an integral manifold).
● Care must be taken to prevent contaminants from reaching O-
ring surfaces. If O-ring surfaces require cleaning, use a lint-
free applicator with alcohol, Freon, or acetone to remove dirt
and lightly lubricate the O-ring surface with silicon oil. The oil
l is not provided in the maintenance kit.
● Never use sharp objects to cut tubing from the bulged tubes.
The tiny scratches left on the tubes could cause leaks.
In the process of performing general maintenance on a module and in printed-circuit board
replacement, the following tools may be required:
● 3/32" and 5/64" Allen-head screwdrivers,
● 3/16" hex wrench,
● needle nose tweezers,
● #0 Phillips-head screwdriver, and
● small adjustable wrench.
