Operating environment
•Select the correct type of enclosure according to the operating environment.
IP67 protection class is achieved when the following conditions are met.
(1) The units are connected correctly using power supply cables and communication cables with M12 (or M8)
connectors.
(2) Suitable mounting of each unit and manifold valve.
(3) Be sure to fit a water resistant cap on any unused connectors.
If using in an environment that is exposed to water splashes, please take protective measures, such as using a
cover.
Do not use in an atmosphere having water, water steam, or where there is direct contact with any of these. These
may cause failure or malfunction.
•Do not use the product in a place where the product could be splashed by oil or chemicals.
Operating in environments with coolants, cleaning solvents, various oils or chemicals may cause adverse effects
(failure, malfunction) to the unit even in a short period of time.
•Do not use the product in an environment where corrosive gases or fluids can be splashed.
Otherwise damage to the unit can result, causing malfunction.
•Do not use in an area where surges are generated.
If there is equipment generating large surge near the unit (magnetic type lifter, high frequency inductive furnace,
welding machine, motor, etc.), this can cause deterioration of the internal circuitry element of the unit or result in
damage. Take measures against the surge sources, and prevent the lines from coming into close contact.
•When a surge-generating load such as a relay, valve, or lamp is directly driven, use the product with
built in surge protection.
Direct drive of a load generating surge voltage can damage the unit.
•The product is CE marked, but is not immune to lightning strikes. Take measures against lightning
strikes in the system.
•Prevent foreign matter such as dust or wire debris from entering inside the product.
Otherwise it can cause damage or malfunction.
•Mount the product in a place that is not exposed to vibration or impact.
Otherwise it can cause damage or malfunction.
•Do not use the product in an environment that is exposed to temperature cycles.
Heat cycles other than ordinary changes in temperature can adversely affect the inside of the product.
•Do not expose the product to direct sunlight.
If using in a location directly exposed to sunlight, shade the product from the sunlight.
Otherwise it can cause damage or malfunction.
•Keep within the specified ambient temperature range.
Otherwise malfunction can result.
•Do not operate close to a heat source, or in a location exposed to radiant heat.
Otherwise malfunction can result.
Adjustment and Operation
•Perform settings suitable for the operating conditions.
Incorrect setting can cause operation failure.
(Refer to "Setting and Adjustment".)
•Please refer to the PLC manufacturer's manual, etc. for details of PLC-side programming and
addresses.
For the PLC protocol and programming, refer to the relevant manufacturer's documentation.
