Chapter 4 – Maintenance
The 3600 series 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.
••••
Clean or change the fan filter periodically to ensure that the air circulating in the
unit is clean. Wash the filter with warm water and dish soap, and let it air dry.
Do not scrub the filter, and do not reinstall it into the unit until it is completely
dry.
••••
Base your maintenance schedule on the type of environment the system is in
(i.e., if the area is dusty, you should schedule maintenance more often than if it is
a dry, clean area). Check the filter often to determine if it needs to be changed
ahead of schedule.
••••
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 3600 unit.

replacement.

To change the fan filter, remove the grill and filter as illustrated in Figure 4–1 and
replace the filter. Then snap the assembly back into position.
