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.
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.
Warning
• The compatibility of pneumatic equipment is the responsibility of the
person who designs the pneumatic system or decides its specifications.
Since the products specified here can be used in various operating
conditions, their compatibility with the specific pneumatic system must
be based on specifications or after analysis and or tests to meet specific
requirements.
• Only trained personnel should operate pneu atically operated
achinery and equip ent.
Compressed air can be dangerous if an operator is unfamiliar with it.
Assembly, handling or repair of pneumatic systems should be performed
by trained and experienced personnel.
• Do not service achinery/equip ent or atte pt to re ove
co ponents until safety is confir ed.
1) Inspection and maintenance of machinery equipment should only be
performed after confirmation of safe locked-out control positions.
2) When equipment is to be removed, confirm the safety process as
mentioned above. Switch off air and electrical supplies and exhaust all
residual compressed air in the system.
3) Before machinery equipment is re-started, ensure all safety measures
to prevent sudden movement of cylinders etc. (Supply air into the system
gradually to create back pressure, i.e. incorporate a soft-start valve).
• Do not use this product outside of the specifications. Contact SMC
if it is to be used in any of the following conditions:
1) Conditions and environments beyond the given specifications, or if the
product is to be used outdoors.
2) Installations in conjunction with atomic energy, railway, air navigation,
vehicles, medical equipment, food and beverage, recreation equipment,
emergency stop circuits, press applications, or safety equipment.
3) An application which has the possibility of having negative effects on
people, property, or animals, requiring special safety analysis.
Caution
• Ensure that the air supply system is filtered to 5 microns.

3 Installation
3.1 Installation
Warning
• Do not install the product unless the safety instructions have been read
and understood
3.2 Environ ent
Warning
• Do not use in an environment where corrosive gases, chemicals, salt
water or steam are present.
• Do not use in an explosive atmosphere.
• Do not expose to direct sunlight. Use a suitable protective cover.
• Do not install in a location subject to vibration or impact. Check the
product specifications.
• Do not mount in a location exposed to radiant heat.
3.3 Piping
Warning
• Before piping make sure to clean up chips, cutting oil, dust etc.
• When installing piping or fittings, ensure sealant material does not enter
inside the port. When using seal tape, leave 1.5 to 2 threads exposed on
the end of the pipe fitting.
• Tighten fittings to the specified tightening torque.
Thread Tightening Torque
M5 By hand + 1 6 turn with a wrench (1 4 turn for miniature fittings)
Rc 1 8 7 to 9
3.4 Electrical Connection
Caution
• When DC power is connected to a solenoid valve equipped with light
and or surge voltage suppressor, check for polarity indications.
• For polarity indications:
• No diode to protect polarity: if polarity connection is wrong, the
diode in the valve or switching device at control equipment or
power supply may be damaged.
• With diode to protect polarity: if polarity connection is wrong, the
valve does not switch.
Vacuum Pressure Switch Wiring Diagram (ZSE30A type)
Wiring electronic Pressure Switch
• Confir wire colours and ter inal nu bers when wiring.
Since incorrect wiring can lead to breakage or failure of the switch as
well as malfunction, perform wiring after confirming wiring colours and
terminal numbers with the instruction manual.
• Avoid repeatedly bending or stretching lead wires.
Broken lead wires will result from applying bending stress or stretching
force to the lead wires. In the event that lead wires are damaged
creating a possibility of malfunction, replace the entire product. (For
cases in which the lead wires cannot be replaced through grommets.)
• Confir proper insulation of wiring.
Be certain that there is no faulty wiring insulation (contact with other
circuits, ground fault, improper insulation between terminals, etc.).
Damage may occur due to excess current flow into a switch.
• Do not wire with power lines or high voltage lines.
Wire separately from power lines or high voltage lines, avoiding parallel
wiring or wiring in the same conduit. Control circuits containing switches
may malfunction due to noise from other lines.
• Do not allow short circuiting of loads.
Use caution, as switches will be damaged if a load is short circuited. Be
especially careful not to reverse the power supply line (Brown) and the
output line (Black).

3.5 Mounting
• Read the instruction anual carefully.
The product should be mounted and operated with a good
understanding of its contents. Also, keep the manual where it can be
easily referred to at any time.
• Ensure space for aintenance.
Ensure the necessary space for maintenance activities.
• Be sure to tighten screws with the proper torque.
When mounting, tighten screws with the recommended torque.
• Do not obstruct the exhaust port of the ejector.
If the exhaust port is obstructed when mounted, a vacuum will not be
generated.
Electronic Pressure Switch
• Do not use if equip ent does not operate properly.
Verify correct mounting by suitable function and leakage inspections
after air and power are connected following mounting or maintenance.
• Do not drop or bu p.
Do not drop, bump or apply excessive impact (1000m s²) when handling.
Even if the switch body is not damaged, the switch may suffer internal
damage that will lead to malfunction.
• Hold the product fro the body side when handling.
The tensile strength of the power cord is 49N, and pulling it with a force
greater than this can cause failure. Hold by the body when handling.
• Turn the setting tri er gently using a watch akers screwdriver.
Turn the setting trimmer gently using a watchmakers screwdriver. Do not
turn beyond the stoppers located at both ends. If the trimmer is broken,
adjustment will be impossible.
• Pressure port
Do not insert wire, etc., from the pressure port. This will damage the
pressure sensor, making it impossible to obtain normal operation.
3.6 Air Supply Circuit
• When designing the air supply circuit ensure that pipe sizes have
sufficient capacity to prevent any pressure drop within the generator, this
also applies to valves and fittings.
• The supply air should be clean and oil free.
• Vacuu circuit
Ensure that the piping from generator to vacuum pad is kept as short as
possible to prevent restriction and leakage.
• Vacuu pads
When installing vacuum generators the rule is one generator → one
vacuum pad. If this rule is ignored then possible loss of vacuum during
pick-up will occur.
4 Maintenance
4.1 General Maintenance
• Not following proper maintenance procedures could cause the product to
malfunction and lead to equipment damage.
• If handled improperly, compressed air can be dangerous. Maintenance
of pneumatic systems should be performed only by qualified personnel.
• Before performing maintenance, turn off the power supply and be sure to
cut off the supply pressure. Confirm that the air is released to
atmosphere.
• After installation and maintenance, apply operating pressure and power
to the equipment and perform appropriate functional and leakage tests to
make sure the equipment is installed correctly.
• Do not make any modification to the product.
• Do not disassemble the product, unless required by installation or
maintenance instructions.
