Chapter 4 – Maintenance
The 3700 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 3700 unit.
Fuse Replacement
The 3700 unit has no accessible fuse. Return the unit to the factory for fuse
replacement.
