■Precautions for Handling
○Follow the instructions given below for the selection and handling of the product.
●The instructions on selection (installation, wiring, environment, adjustment, operation, maintenance, etc.)
described below must be followed.
Product specifications
•This product is not suitable for applications to shut off the flow rate completely.
If it is necessary to shut off the flow rate completely, install a stop valve, etc. separately.
•Use within the specified voltage.
Otherwise failure or malfunction can result.
•For details of the compressed air quality, refer to JIS B 8392-1 1.6.2.

●Product Handling
Mounting
•If a commercially available switching power supply is used, be sure to ground the frame ground (FG)
terminal.
•Do not drop, hit or apply excessive shock to the product.
Otherwise damage to the internal components may result, causing malfunction.
•Do not pull the lead wire forcefully, or lift the product by the lead wire.
The product will be damaged, leading to failure and malfunction.
•The product should be flushed out by air blow to remove any dust left in the piping before connecting the
piping to the product.
Otherwise it can cause damage or malfunction.
•Refer to the flow direction of the fluid indicated on the product label during installation and piping.
•Do not mount the product with the display facing downward.
•Do not insert metal wires or other foreign matter into the piping ports.
This can damage the sensor causing failure or malfunction.
•Never mount the product in a place that will be used as a foothold during piping.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
•If there is a risk of foreign matter entering the fluid, install a filter or mist separator on the IN side (entry
side) to avoid failure and malfunction.
Otherwise it can cause damage or malfunction. The product will be unable to measure accurately or control the flow
rate.
Refer to the figure below for the recommended pneumatic circuit.
•If the fluid flow on the IN side (entry side) of the product is unstable, correct measurement and flow rate
control will not be possible.
If a valve is used on the IN side (entry side) of the product, the flow may be disturbed due to the change of the
effective area.
•Do not install a restrictor immediately on the product OUT side (outlet).
Otherwise, the flow control action may be unstable.

Wiring (Including connecting/disconnecting of the connectors)
•Do not pull hard on the lead wire.
Especially never lift the product equipped with fitting and piping by holding the lead wires.
Otherwise damage to the internal components may result, causing malfunction or connectors dropping off.
•Avoid repeatedly bending, stretching or applying a heavy object to the lead wire.
Repetitive bending stress or tensile stress can cause the sheath of the wire to peel off, or breakage of the wire.
If the lead wire can move, fix it near the product.
The recommended bend radius of the lead wire is 6 times the outside diameter of the sheath, or 33 times the
outside diameter of the insulation material, whichever is larger.
Replace the damaged lead wire with a new one.
•Wire correctly.
Incorrect wiring may cause malfunction or damage to the product.
•Do not perform wiring while the power is on.
Otherwise damage to the internal components may result, causing malfunction.
•Do not route wires and cables together with power or high voltage cables.
Route the wires of the product separately from power or high voltage cables to prevent noise and surge of signal
lines from entering the product.
•Confirm correct insulation of wiring.
Poor insulation (interference with other circuits, poor insulation between terminals, etc.) can apply excessive voltage
or current to the product causing damage.
•Keep wiring as short as possible to prevent interference from noise and surge voltage.
Wire the DC( - ) line(blue) as close as possible to the power supply.
•When the analogue output is used, install a noise filter (line noise filter, ferrite element, etc.) between the
switch-mode power supply and the product.

Operating environment
•Do not use in an atmosphere containing corrosive gases, chemicals, sea water, 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.
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, or hardening of the lead wires).
•Do not use in an area where electrical surges are generated.
When there are machines or equipment that generate large surges near the product (magnetic type lifter, high
frequency inductive furnace, motor, etc.), this can result in deterioration and damage of the internal circuit elements.
Take protective measures to isolate the surge sources and prevent the lines from coming into close contact.
•Do not use a load which generates a surge voltage.
When a surge voltage-generating load such as a relay or solenoid valve is directly driven, use the product with a
surge absorbing element built-in.
•The product is CE/UKCA marked but is not immune to lightning strikes. Take measures against lightning
strikes in the system.
•Mount the product in a location that is not affected by vibration or impact.
Otherwise, a failure or malfunction may be caused.
•Do not use the product in the presence of a magnetic field.
Otherwise, a malfunction of the product may be caused.
•Do not let foreign matter, such as wire debris, get inside the product.
Otherwise, a failure or malfunction may be caused.
•Do not use the product in an environment that is exposed to temperature cycles.
Temperature cycles other than ordinary changes in temperature can adversely affect the internal components 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, a malfunction may be caused.
•Keep within the specified temperature range.
Operation under low temperature may lead to damage or operation failure due to frozen moisture in the air.
Protection against freezing is necessary.
The installation of an air dryer is recommended for elimination of drainage and water.
Avoid abrupt temperature changes even within the specified temperature range.
•Do not operate close to a heat source, or in a location exposed to radiant heat.
Otherwise malfunction can result.
•Do not install the products close to each other or do not close the vent hole when installing the product.
Otherwise, the temperature of the product may rise, resulting in a failure or malfunction.

Adjustment and operation
•Connect the load before turning the power supply on.
•Do not short-circuit the load.
•Confirm that the fluid is flowing in the pipe when controlling the flow rate.
If there is no supply pressure, a current beyond the product specifications may flow in the event of an error in control
action.
•If the controlled flow rate does not continuously reach the commanded flow rate for at least 5 seconds, it
will result in a control error and the flow control will stop.
•Do not touch the LCD during operation.
The display can vary due to static electricity.
•When the product is not energized, the valve is fully closed (normally closed (N.C.)).
•Do not supply a pressure that is higher than that in the IN side to the OUT side.
Otherwise, the control valve will open, causing the fluid to flow backward.
Maintenance
•Perform regular maintenance and inspections.
There is a risk of unexpected failure of components due to the malfunction of equipment and machinery.
•Before performing maintenance, turn off the power supply, stop the air supply, exhaust the residual
compressed air in the piping, and verify the release of air.
Otherwise, unintended malfunction of system components can result.
•Remove the condensate periodically.
If condensate enters the OUT side, it can cause operating failure of pneumatic equipment.
•Do not use solvents such as benzene, thinner, etc. to clean the product.
This may damage the surface of the body or erase the markings on the body.
Use a soft cloth to remove stains.
For heavy stains, use a damp cloth soaked with diluted neutral detergent and fully squeezed, then wipe up the
stains again with a dry cloth.
