10-1 Cleaning and Inspection
This section describes daily maintenance and the cleaning and inspection methods.
Inspect the High-speed Analog Input Units daily or periodically in order to keep it in optimal operating
condition.
10-1-1
Cleaning
Clean the High-speed Analog Input Units regularly as described below in order to keep it in optimal
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
sufficiently diluted detergent (2%) and wrung dry.
• A smudge may remain on the NX Unit from gum, vinyl, or tape that was left on for a long time. Re-
move the smudge when cleaning.
Precautions for Correct Use
• Never use volatile solvents, such as paint thinner, benzene, or chemical wipes.
• Do not touch the NX bus connectors.
10-1-2
Periodic Inspections
Although the major components in NX Units have an extremely long life time, they can deteriorate un-
der improper environmental conditions. Periodic inspections are thus required.
Inspection is recommended at least once every six months to a year, but more frequent inspections
will be necessary in adverse environments.
Take immediate steps to correct the situation if any of the conditions in the following table are not met.
Periodic Inspection Items

1
External
power
supply
Is the power supply voltage
measured at the terminal
block within standards?
Within the power sup-
ply voltage range
Use a voltage tester to check the
power supply at the terminals. Take
necessary steps to bring the power
supply within the power supply volt-
age range.
2
I/O power
supply
Is the power supply voltage
measured at the I/O terminal
block within standards?
Voltages must be with-
in I/O specifications of
each NX Unit.
Use a voltage tester to check the
power voltage at the terminals.
Take necessary steps to bring the
I/O power supply within NX Unit
standards.
