11-1 Cleaning and Maintenance
This section describes daily maintenance and the cleaning and inspection methods.
Inspect the Position Interface Units daily or periodically in order to keep it in optimal operating condition.
Clean the Position Interface Units regularly as described below in order to keep it in optimal operating
condition.
• Wipe the Units over with a soft, dry cloth when doing daily cleaning.
• If dirt remains even after wiping with a soft, dry cloth, wipe over with a cloth that has been wet with a
sufficiently diluted detergent (2%) and wrung dry.
• A smudge may remain on the Unit from gum, vinyl, or tape that was left on for a long time. Remove
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 connector.
Although the major components in Position Interface Units have an extremely long life time, they can
deteriorate under 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
No. Item Inspection Criteria Action
1Power
supplies
Measure the power supply
voltage at the terminal
blocks, and make sure that
the voltage fluctuation is
within the criteria voltage.
The voltage must be
within the power supply
voltage range.
Use a voltage tester to check the
power supply at the terminals. Take
necessary steps to bring voltage of
the supplied power to within the
allowable voltage fluctuation range.
2I/O
power
supplies
Measure the power supply
voltages at the input and out-
put terminal blocks, and
make sure that the voltage
fluctuation is within the crite-
ria voltage.
The voltages must be
within the I/O specifica-
tions for each NX Unit.
Use a voltage tester to check the
power supply at the terminals. Take
necessary steps to bring voltage of
the I/O power supplies to within the
I/O specifications of each Unit.
