Warning
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:

1 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 indicates a hazard with a low level of risk
which, if not avoided, could result in minor or
moderate injury.
Caution
Warning
Danger
WARNING indicates a hazard with a medium level
of risk which, if not avoided, could result in death or
serious injury.
DANGER indicates a hazard with a high level of risk
which, if not avoided, will result in death or serious
injury.
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.
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 might
be 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.
Use within the specified operating pressure.
Otherwise it can cause damage to the Pressure Sensor or inability to
measure correctly.
If fluid is supplied at a pressure exceeding the proof pressure, the ceramic
diaphragm will be damaged which may short circuit the power supply.
Please use a power supply which includes short circuit protection.

Wiring
Connector pin numbers
When the lead wire and connector (ZS-37-A or ZS-37-B) designated for
the PSE570 is used, the wire colours will apply as shown in the
diagram.
How to connect the body and the lead wire and connector
•Align the lead wire connector with the connector key groove, and insert
vertically.
•Connection is complete when the knurled part is fully tightened. Check
that the connection is not loose.
