Caution
Safety Instructions
This manual contains essential information for the protection of users
and others from possible injury and/or equipment damage.
•Read this manual before using the product, to ensure correct handling,
and read the manuals of related apparatus before use.
•Keep this manual in a safe place for future reference.
•These instructions indicate the level of potential hazard by label of
"Caution", "Warning" or "Danger", followed by important safety
information which must be carefully followed.
•To ensure safety of personnel and equipment the safety instructions in
this manual and the product catalogue must be observed, along with
other relevant safety practices.
Caution
CAUTION indicates a hazard with a low level of risk
which, if not avoided, could result in minor or
moderate injury.
Warning
WARNING indicates a hazard with a medium level
of risk which, if not avoided, could result in death or
serious injury.
Danger
•Do not touch the terminals and connectors while the power is on.
Otherwise electric shock, malfunction or damage to the product can result.
•After maintenance is complete, perform appropriate functional
inspections and leak tests.
Stop operation if the equipment does not function properly or there is a
leakage of fluid.
When leakage occurs from parts other than the piping, the product is
faulty.
Disconnect the power supply and stop the fluid supply.
Do not apply fluid under leaking conditions.
Safety cannot be assured in the case of unexpected malfunction.
Panel mounting
•Insert Panel Mount Adapter B (supplied as an accessory) into Section A of
Panel Mount Adapter A.
Push Panel Mount Adapter B from behind till the display is fixed onto the
panel.
The pin of Panel Mount Adapter B engages the notched part of Panel
Adapter C to fix the display.
•The switch can be mounted on a panel with a thickness of 1 to 3.2 mm.
•See the illustration below for panel cut out dimensions.

NOTE
•The direct current power supply to be used should be UL approved as
follows:
Circuit (class 2) which is of maximum 30 Vrms (42.4 V peak), with UL 1310
class 2 power supply unit or UL 1585 class 2 transformer.
•The Flow switch is a
approved product only if it has a
mark on
the body.

•For one-touch fitting, insert the tube to the end so that it cannot be
pulled out.
•Insertion with excessive force can cause damage.
•Ensure there is no leakage after piping.
•Use this product within the specified operating pressure range and
operating temperature range.
•Withstand pressure is 1.0 MPa.
This product is class A equipment that is intended for use in an industrial
environment.
There may be potential difficulties in ensuring electromagnetic
compatibility in other environments due to conducted as well as radiated
disturbances.
•Do not disassemble, modify (including changing the printed circuit
board) or repair.
An injury or failure can result.
•Do not operate the product outside of the specifications.
Do not use for flammable or harmful fluids.
Fire, malfunction, or damage to the product can result.
Verify the specifications before use.
•Do not operate in an atmosphere containing flammable or
explosive gases.
Fire or an explosion can result.
This product is not designed to be explosion proof.
•Do not use the product in a place where static electricity is a
problem.
Otherwise it can cause failure or malfunction of the system.
•If using the product in an interlocking circuit:
•Provide a double interlocking system, for example a mechanical
system
•Check the product regularly for proper operation
Otherwise malfunction can result, causing an accident.
•The following instructions must be followed during maintenance:
•Turn off the power supply
•Stop the air supply, exhaust the residual pressure and verify that
the air is released before performing maintenance.
Otherwise an injury can be caused.

Model Indication and How to Order
DANGER indicates a hazard with a high level of risk
which, if not avoided, will result in death or serious
injury.
Warning
Piping
•Ensure tightening torque is correct when installing piping.
•Refer to the following table for the appropriate torque values.
•Hold the metal part with a spanner when piping.

DIN rail mounting
•The tightening torque for DIN rail mounting screws and joint screws should
be 0.4±0.05 Nm.
Wiring
Connection
•Make connection after turning the power off.
•Use a separate route when installing wire. Malfunction stemming from
noise may occur if wire is installed in the same route as that of power or
high-voltage cable.
•Be sure to ground terminal FG when using a switching regulator
obtained on the market. If analogue output is performed connecting to a
switching regulator obtained on the market, switching noise will be
superimposed and product specification can no longer be met. This can
be prevented by inserting a noise filter, such as a line noise filter and a
ferrite element, between the switching regulator and the pressure
switch, or by using a series power supply instead of a switching
regulator.
Connector
Connecting/Disconnecting
•When connecting the connector, insert it straight onto the pin holding
the lever and connector body between fingers and lock the connector by
pushing the lever claw into the square groove in the body of the switch.
•When disconnecting the connector, push down the lever by thumb to
disengage the lever claw from the square groove. Then pull the
connector straight out.

the switch will be turned off.
The switch is adjusted such that it will be turned on with the center point
of a flow rate setting range for each product specification.
If the operation shown below doesn't cause any problem, do not change
