•Product handling
∗Installation
•Do not drop, hit or apply excessive shock to the fieldbus system.
Otherwise damage to the product can result, causing malfunction.
•Tighten to the specified tightening torque.
If the tightening torque is exceeded the mounting screws may be broken.
IP67 protection cannot be guaranteed if the screws are not tightened to the specified torque.
•Never mount a product in a location that will be used as a foothold.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
∗Wiring
•Avoid repeatedly bending or stretching the cables, or placing heavy load on them.
Repetitive bending stress or tensile stress can cause breakage of the cable.
•Wire correctly.
Incorrect wiring can break the product.
•Do not perform wiring while the power is on.
Otherwise damage to the fieldbus system and/or I/O device can result, causing malfunction.
•Do not route wires and cables together with power or high voltage cables.
Otherwise the fieldbus system and/or I/O device can malfunction due to interference of noise and surge voltage
from power and high voltage cables to the signal line.
Route the wires (piping) of the fieldbus system and/or I/O device separately from power or high voltage cables.
•Confirm proper insulation of wiring.
Poor insulation (interference from another circuit, poor insulation between terminals, etc.) can lead to excess
voltage or current being applied to the product, causing damage.
•Take appropriate measures against noise, such as using a noise filter, when the fieldbus system is
incorporated into equipment.
Otherwise noise can cause malfunction.
∗Environment
•Select the proper type of protection according to the environment of operation.
IP67 protection is achieved when the following conditions are met.
(1) The units are connected properlywith fieldbus cable with M12 connector and power cable with M12 (M8)
connector.
(2) Suitable mounting of each unit and manifold valve.
If using in an environment that is exposed to water splashes, please take measures such as using a cover.
•Do not use in a place where the product could be splashed by oil or chemicals.
If the product is to be used in an environment containing oils or chemicals such as coolant orcleaning solvent, even
for a short time, it may be adversely affected (damage, malfunction etc.).
•Do not use the product in an environment where corrosive gases or fluids could besplashed.
Otherwise damage to the product and malfunction can result.
•Do not use in an area where surges are generated.
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.
•When a surge-generating load such as a relay or solenoid is driven directly, use an fieldbus system with
a built-in surge absorbing element.
Direct drive of a load generating surge voltage can damage the fieldbus system.
•The product is CE marked, but not immune to lightning strikes. Take measures against lightning strikes
in the system.
•Prevent foreign matter such as remnant of wires from entering the fieldbus system to avoid failure and
malfunction.

○Output number assignment
Output data
∗: The output number refers to the solenoid position on the manifold and starts at zero.
∗: Standard wiring on the manifold is for double-solenoid valves and output number starts A side and B side in that order as shown in
the figure a.
If you mount a single-solenoid valve on the standard wiring manifold, output number for B side valve is skipped.
∗: Custom wiring for mixed mounting single-solenoid valves and double-solenoid-valves can be specified with a Wiring Specification
Sheet. Example wiring is shown in the figure b.
∗: Bit status “0” and ”1” on a data corresponds solenoid valve status ON and OFF (0: OFF, 1: ON), and output number starts at zero
from LSB (least significant bit).
