11-4 Maintenance
1560D-UM051D-EN-P – February 2005
Periodic Inspection (cont.) "Keep Good Maintenance Records"
This rule will be most helpful in locating possible intermittent problems by
pointing to a particular area of recurring trouble within the overall system.
Furthermore, good maintenance records will help reduce major, costly
shutdowns by demanding the use of proper test equipment and an appropriate
inventory of spare parts. For additional information see NFPA 70B,
"RECOMMENDED PRACTICE FOR ELECTRICAL EQUIPMENT
MAINTENANCE", published by the National Fire Protection Association.
Power Components
Power components should be kept clean and free of dirt and obstructions.
This will avoid tracking and heat build-up, thereby increasing the life of
the device.
Control Components – Electronic
The printed circuit boards are to be kept clean and free of any accumulations
of dirt and foreign materials.
Materials which create static electricity should never be allowed near circuit
boards while in the unit, or in storage. Caution should be used when one
is near or handling circuit boards. There are no other requirements, other
than housekeeping standards, that the maintenance program requires on
the logic control components.
Fans
Physically rotating and observing the fans for noise or binding will
indicate if fan failure is evident.
Interlocks
Verify that interlocks function as intended, and have not been forced,
damaged or removed.
Barriers
Verify that all barriers are in place and securely fastened.
