Safety Instructions
Mounting and Installation
Warning
Installation
Do not disassemble, modify (including changing the printed circuit board) or repair.
An injury or failure can result. •Never mount the product in a location that will be used as a foothold.
•The rotation angle of the monitor is 270
Do not operate the product outside of the specifications.
Do not use for flammable or harmful fluids. part with excessive force will damage the end stop.
Fire, malfunction, or damage to the product can result.
Verify the specifications before use.
Do not operate in an atmosphere containing flammable, explosive or corrosive gas.
Fire or an explosion can result.
This product is not designed to be explosion proof.
Do not use the product for flammable or highly permeable fluids.
180°
A fire or explosion can result.
Do not use the product in a place where static electricity is a problem.
Otherwise it can cause failure or malfunction of the system.
IN side
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.
Installing
The following instructions must be followed during maintenance:
•Turn off the power supply •Install the product (with bracket) using the
•Ensure the flow is shut off before performing maintenance
M4 screws (4 pcs.) supplied.
Otherwise an injury can result.
•Bracket thickness is approximately 1.6 mm

Do not touch the terminals and connectors while the power is on.
for more information about mounting hole dimensions.
Otherwise electric shock, malfunction or damage to the product can result.
Do not touch the piping or its connected parts when the fluid is at high temperature.
Piping
It may lead to burnt.
Ensure the piping cools sufficiently before touching.
•Use the product within the specified operating pressure range and temperature range.
After maintenance is complete, perform appropriate functional inspections and leak tests. •Proof pressure is 1.0 MPa for air and 1.5 MPa for water.
Stop operation if the equipment does not function properly or there is a leakage of fluid.
•Connect the piping to the fittings.
When leakage occurs from parts other than the piping, the product might be faulty.
•Mount the product so that the fluid direction is the same as the arrow indicated
Disconnect the power supply and stop the fluid supply.
on the product.
Do not apply fluid under leaking conditions.
Safety cannot be assured in the case of unexpected malfunction.
•Never mount the product for air upside down.
•The piping on the IN side must have a straight section of piping whose length
is 8 times the piping diameter or more.
Maintenance
•Avoid sudden changes in the piping size on the IN side of the product.
How to reset the product after a power cut or forcible de-energizing
The setting of the product will be retained as it was before a power cut or
de-energizing.
The output condition is also basically recovered to that before a power cut or
de-energizing, but may change depending on the operating environment.
Therefore, check the safety of the whole installation before operating the product.
•If the product for water is mounted vertically, let the liquid flow from bottom to top.
In case of the product for water trapped air bubbles can cause errors in
measurement accuracy.
(If the fluid detection path is always filled with liquid, there will be no problem.)
Connecting the piping
•Ensure that the metal piping attachments are tightened to the required torque
(refer to the table below).
•If the tightening torque is exceeded, the product can be broken. If the
tightening torque is insufficient, the fittings may become loose.
Connector pin numbers
(On the product) •When connecting piping to the product, a spanner should be used on the
metal piping attachment only. Using a spanner on other parts may damage
