10-1 Cleaning and Inspection

This section describes daily device maintenance such as cleaning and inspection.
Make sure to perform daily or periodic inspections in order to maintain the Digital I/O Unit's functions in
the best operating condition.

10-1-1 Cleaning

Perform the following cleaning procedures periodically to ensure Digital I/O Units are maintained in the
best operating condition.
• Wipe the equipment over with a soft, dry cloth when performing daily cleaning.
• If dirt remains even after wiping with a soft, dry cloth, wipe with a cloth that has been wet with a suffi-
ciently diluted detergent (2%) and wrung dry.
• Units will become stained if items such as rubber, vinyl products, or adhesive tape are left on the NX
Unit for a long period. Remove such items during regular cleaning.
Precautions for Correct Use
• Never use benzene, thinners, other volatile solvents, or chemical cloths.
• Do not touch the NX bus connectors.

10-1-2 Periodic Inspection

NX Units do not have parts with a specific life. However, its elements can deteriorate under improper
environmental conditions. Periodic inspections are thus required to ensure that the required conditions
are being maintained.
Inspection is recommended at least once every six months to a year, but more frequent inspections
may be necessary depending on the severe environments.
Take immediate steps to correct the situation if any of the conditions in the following table are not met.
