Chapter 4 – Maintenance
The 4117T is designed to withstand the harsh environment of the factory floor.
Routine maintenance can help keep your system in good operating condition.
Preventive maintenance consists of several basic procedures that will greatly reduce
the chance of system malfunction. Schedule preventive maintenance along with the
regular equipment maintenance to minimize down time.
General Preventive Maintenance
Here are some preventive measures you can take:
•
•
•
•
Clean the monitor screen using a non-residue cleaner such as a mild window
cleaning solution or CRT screen cleaner. Take care not to scratch the screen
face.
•
•
•
•
Remove dust and dirt from PC components
. If dust builds up on heat sinks and
circuitry, an obstruction of heat dissipation could cause the unit to malfunction.
If dust reaches the electronic boards, a short circuit could occur.
•
•
•
•
Check the connections to I/O modules,
especially in environments where
vibration could loosen the connections. Check to see that all plugs, sockets,
terminal strips, and module connections are solid.
•
•
•
•
Remove unnecessary articles, such as drawings or manuals, from the unit.
They
can obstruct airflow and create hot spots, which cause the system to malfunction.
•
•
•
•
Do not place noise-generating equipment near the 4117T unit.
Fuse Replacement
The 4117T unit has no accessible fuse. Return the unit to the factory for fuse
replacement.
Recommended Hard Drive Preventive Maintenance
Pro-face has recognized that hard drive failures may begin to increase an average of
four to five years into the life of most computers used in industrial applications.
Therefore, it is our recommendation as a preventive maintenance measure that all
hard drives used in these types of applications be replaced at a two year interval to
avoid any down time related to hard drive failure.
