• Environment
o Select the proper type of protection according to the operating environment.
o IP65 protection is achieved when the following conditions are met. The units are connected
properly with fieldbus cable with M12 connector and power cable with M12 connector. All
unused connectors are closed with a properly installed seal cap.
o If using in an environment that is exposed to water splashes, please take measures such as
using a cover.
o Do not use in a place where the product could be splashed by oil or chemicals.
o If the product is to be used in an environment containing oils or chemicals such as coolant or
cleaning solvent, even for a short time, it may be adversely affected (damage, malfunction etc.).
o Do not use the product in an environment where corrosive gases or fluids could be splashed.
Otherwise damage to the product and malfunction can result.
o Do not use in an area where surges are generated.
o If there is equipment which generates a large amount of surge (solenoid type lifter, high
frequency induction furnace, motor, etc.) close to the fieldbus system, this may cause
deterioration or breakage of the internal circuit of the fieldbus system. Avoid sources of surge
generation and crossed lines.
o When a surge-generating load such as a relay or solenoid is driven directly, use a fieldbus
system with a built-in surge absorbing element.
o Direct drive of a load generating surge voltage can damage the fieldbus system.
o The product is NOT immune to lightning strikes. Take measures against lightning strikes in the
system.
o Prevent foreign matter such as remnant of wires from entering the fieldbus system to avoid
failure and malfunction.
o Mount the product in a place that is not exposed to vibration or impact.
▪ Failure or malfunction can result.
o Do not expose the product to direct sunlight.
o If using in a location directly exposed to sunlight, shade the product from the sunlight. Failure
or malfunction can result.
o Keep within the specified operating temperature range.
▪ Malfunction can result.
o Do not operate close to a heat source, or in a location exposed to radiant heat.
▪ Malfunction can result.
• Adjustment and Operation
o Perform settings suitable for the operating conditions.
▪ Incorrect setting can cause operation failure.
o Please refer to the PLC manufacturer's manual etc. for details of programming and addresses.
▪ For the PLC protocol and programming refer to the relevant manufacturer's
documentation.
• Maintenance
o Turn off the power supply, stop the supplied air, exhaust the residual pressure and verify the
release of air before performing maintenance.
▪ There is a risk of unexpected malfunction.
o Perform regular maintenance and inspections.
▪ There is a risk of unexpected malfunction.
o After maintenance is complete, perform appropriate functional inspections.
