afety Instructions

•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.

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 sensor is a approved product only if it has a mark
on the body.

•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.

Bracket mounting

•Fasten the bracket mounting screws to a torque of 0.5±0.05 Nm.

Self tapping
screws

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.

•For one-touch fitting, insert the tube to the end so that it cannot be
pulld 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.

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 sensor.

•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.
