Chapter 5 – Maintenance
The 3510/3512/3510KP/3512KP are 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.
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 re-install 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 shock
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 air flow and create hot spots, which causes the system to
malfunction.
•
Do not place noise-generating equipment near the 3510/3512
.
•
Stock spare parts
to minimize down time resulting from part failure. Spare parts
stocked should be 10 percent of the number of each unit used. Main CPU cards
should have one spare each. Each power supply should have a back-up. In
applications where immediate operation of a failed system is required, you may
need to stock an entire spare computer module. Refer to the Spare Parts List in
this chapter.
•
Replace the module with the correct type.
If the new module solves the problem
but the failure reoccurs, check for inductive loads that may be generating voltage
and current spikes and may require external suppression.
