This product has been designed, developed and manufactured for general-purpose application in machinery and equipment.
Accordingly, when used in the applications outlined below, special care should be taken to implement a fail-safe and/or redundant
design concept as well as a periodic maintenance program.
Never use this product in applications where human safety may be put at risk.
(1) Reduction of noise
• Safety devices for plant worker protection • Start/stop control devices for transportation and material handling machines
• Aeronautical/aerospace machines
The final control devices must be powered up simul-
taneously with or prior to the instrument when the
self-tuning function is to be used.

Even though the noise is small, the noise filter is used
to eliminate the effect of the noise as much as possible.

preventive measures
Generally, the following may be the noise sources in the
installation environment:
Relay and contact, electromagnetic coil, solenoid valve,
power supply line (particularly, 100Vac or more), motor
commutator, phase angle control SCR, radio communica-
tion device, welding machine, high-voltage ignitor, etc.
Use of CR filter is effective to prevent fast rise noise.
After the wiring work has been completed, always
inspect and check the wiring status. Great care should
be taken since incorrect wiring may cause the instru-
ment to malfunction or severe personal injury.

power supply
100 to 240Vac
If a large amount of noise exists, appropriate isolation
transformer and line filter are used to eliminate the
effect of the noise.
Recommended filter:
bundle the primary and secondary power cables together
or put both power cables in the same conduit or duct.
or more away from the power lines and power supply
lines having a voltage of 100Vac or more.
Additionally, do not put these lines together in the same
conduit or duct.
