3.1 Installation

WARNING

• Do not install the product unless the safety instructions have been read
and understood.

• Interlock circuit
If the products are used in an interlock circuit, prepare a double interlock
style circuit with a mechanical protection function for the prevention of a
breakdown. Examine these.

3.2 Environment

WARNING

• Do not use in an environment where the product is directly exposed to
corrosive gases, chemicals, salt water, water or steam.

• Do not use in an explosive atmosphere.

• The product should not be exposed to prolonged sunlight.Use a protective
cover.

• Do not mount the product in a location where it is subject to strong
vibrations and/or shock. Check the product specifications.

• Do not mount the product in a location exposed to radiant heat.
If using in an atmosphere where there is possible contact with water drop­lets, oil, weld spatter, etc., take suitable preventative measures.

• When the solenoid valve is mounted in a control panel or its energized for
a long time, make sure that the ambient temperature is within the valve's
specified range

3.3 Piping

CAUTION

• 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 according to appropriate tightening torque.

3.4 One-touch fitting

CAUTION

Tube attachment

• Take a tube having no flaws on its periphery and cut it off at a right angle.
When cutting the tube, use tube cutters TK-1, 2 or 3. Do not use pincers,
nippers or scissors etc. If cutting is done with tools other than tube cutters,
the tube may be cut diagonally or become flattened. This makes a secure
installation impossible, and causes problems such as air leakage or the
tube being pulled out after installation. Allow some extra length in the tube.

Hold down part of the release bush
with your finger or a similar tool, as
shown in the diagram, and pull out in
the direction indicated by the arrow.

• Grasp the tube and push it in slowly, inserting it securely all the way into
the fitting.

• After inserting the tube, pull on it lightly to confirm that it will not come out.
Problems such as air leakage or the tube being pulled out can occur if the
tube is not inserted securely all the way into the fittings.

Tube detachment

• Push in the release bushing and the collar at the same time.

• Pull out the tube while holding down the release bushing so that it does not
come out. If the release bushing is not pressed down sufficiently there will
be increased bite on the tube and it will become more difficult to pull out.

• When the removed tube is to be used again, cut off the portion which has
been chewed before reusing it. If this is not done then the chewed portion
of the tube can cause problems such as air leakage or difficulty in
removing the tube from the fitting.

3.5 Precautions on other tube brands

CAUTION

• When using non-SMC brand tubes, confirm that the following
specifications are satisfied with respect to the outside diameter
tolerance of the tube.
Nylon tube ±0.1mm
Soft nylon tube ±0.1mm
Polyurethane tube +0.15mm

-0.2mm

x Do not use tubes that do not meet these outside diameter tolerances. It

may not be possible to connect them, or they may cause other
problems, such as air leakage or the tube pulling out after connection.

3.6 Indicator Light/Surge Voltage Suppressor

• Non-polar type

When the solenoid valve has no polarity:

In extreme conditions, there is a possibility of
serious injury or loss of life.

WARNING

If instructions are not followed there is a
possibility of serious injury or loss of life.

• Polar type

When the solenoid valve has polarity:

• With switch

• Extended periods of continuous energisation

• Continuous energisation of the valve for extended periods of time may
have an adverse effect on the solenoid valve performance and the
peripheral equipment. This is due to temperature rises caused by the
heat generated by the coil.
Consult with SMC if a valve will be continuously energised for extended
periods of time or if the energized period per day will be longer than the
de-energized period. It is also possible to shorten the energisation
period by using valves of the N.O.(normally open) type.

• When solenoid valves are mounted in a control panel, employ
measures to radiate away excess heat, so that temperatures remain
within the valve specification range.Be particular ly aware when three or
more stations that are sequentially aligned on the manifold are
continuously energized. This will cause a drastic temperature rise.

3.8 How to Use Plug Connector

CAUTION

When attaching and detaching a connector, first shut off the electric power
and the air supply.Also, crimp the lead wires and sockets securely.

Attaching and detaching connectors

• To attach a connector, hold the lever and connector unit between your
fingers and insert straight onto the pins of the solenoid valve so that the
lever's pawl is pushed into the groove and locks.

• To detach a connector, remove the pawl from the groove by pushing the
lever downward with your thumb, and pull the connector straight out.

4 Maintenance

4.1 General Maintenance

CAUTION

• 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 by qualified personnel only.

• Before performing maintenance ensure the supply pressure is shut off and
all residual air pressure is released from the system.

• After maintenance apply operating pressure and power to the equipment
and check for proper operation and possible air leaks. If operation is
abnormal, verify product set-up parameters.

• Do not make any modification to the product.

• Do not disassemble the product, unless required by installation or
maintenance instructions.

4.2 Fitting Assembly Replacement

CAUTION

By replacing a valve's fitting assembly, it is possible to change the port size
of the 2a, 2b, 1(P), and 3(E) ports. When replacing it, pull out the fitting
assembly after removing the clip with a flat head screwdriver, etc.To mount
a new fitting assembly, insert it into place and then fully reinsert the clip.

• Crimping or lead wires and sockets
Peel 3.2 to 3.7mm of the tip of lead wire, enter the core wires neatly into a
socket and crimp it with a special crimp tool. Be careful so that the cover
of lead wire does not enter into the crimping part.
(Crimping tool: Model no. DXT170-75-1).

Attaching and detaching lead wires with sockets

• Attaching
Insert the sockets into the square holes of the connector (with A,B,C and
N indication), and continue to push the sockets all the way in until the lock
by hooking into the seats in the connector.(When they are pushed in, their
hooks open and they are locked automatically.) Next, confirm that they are
locked by pulling lightly on the lead wires.

• Detaching
To detach a socket from a connector, pull out the lead wire while pressing
the socket's hook with a stick having a thin tip (approx.1mm). If the socket
is used again, spread the hook outward.

5 Limitations of Use

CAUTION

• Leakage voltage

The suppressor residual voltage should be 3 % or less of the rated voltage.

• Surge voltage suppressor

If a surge protection circuit contains non-ordinary diodes such as zener
diodes or varistor, a residual voltage will remain that is in proportion to the
protective elements & the rated voltage. Therefore, give consideration to
surge voltage protection of the controller.In the case of diodes, the residual
voltage is approximately 1 V.

• Low temperature operation

Unless otherwise indicated in the specifications for each valve, operation
is possible to -10°C, but appropriate measures should be taken to avoid
solidification or freezing of drainage and moisture, etc.

• Mounting orientation

Mounting orientation is universal.

• Low frequency operation

Valves should be operated at least once every 30 days to prevent
malfunction. (Use caution regarding the air supply.)

5.1 Supply air

WARNING

• Use clean air

If the compressed air supply includes chemicals, synthetic materials
(including organic solvents), salinity, corrosive gas etc., it can lead to
damage or malfunction.

CAUTION

• Install an air filter

Install an air filter at the upper streamside of the valve. Filtration degree
should be 5µm or less.
