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 pneumatically operated
machinery and equipment.
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 machinery/equipment or attempt to remove
components until safety is confirmed.
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.

3.1 Installation
Warning
•
Do not install the product unless the safety instructions have been read
and understood
3.2 Environment
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.

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
•
Confirm wire colours and terminal numbers 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.)
•
Confirm 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).
