Chapter Four – Maintenance
The 1510 was designed to withstand the harsh environment of the factory floor. Routine
maintenance can help keep your 1510 in good operating condition. Preventive mainte-
nance consists of several basic procedures that significantly reduce the chance of system
malfunction. Schedule preventive maintenance along with the regular equipment mainte-
nance to minimize 1510 down time.
Preventive Maintenance
You can take these preventive measures:
·
Clean 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 operating environment of the system. 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 cir-
cuitry, 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 secure.
·
Remove unnecessary articles, such as drawings or manuals, from the unit. They can
obstruct airflow and create hot spots, which causes the system to malfunction.
·
Do not place noise-generating equipment near the 1510.
·
Stock spare parts
to minimize down time resulting from part failure. The spare parts
stocked should be 10 percent of the number of each unit used. The main CPU cards
should have one spare each. Each power supply should have a back up. In certain
applications where immediate operation of a failed system is required, you may need
to stock a spare computer module.
·
Replace the module with the correct type
.
If the new module solves the problem but
the failure recurs, check for inductive loads that may be generating voltage and cur-
rent spikes and may require external suppression.
Caution
Do not operate the 1510 without a fan filter. Dust build-up could cause
the unit to malfunction.
