Safety Instructions
These safety instructions are intended to prevent a hazardous situa-
tion and/or equipment damage.These instructions indicate the level
of potential hazard by label of “Caution”, “Warning” or “Danger”.
To ensure safety, be sure to observe ISO4414 (Note1), JIS B 8370 (Note2)
and other safety practices.
Note 1: ISO 4414: Pneumatic fluid power – Recommendations for the
application of equipment to transmission and control systems.
Note 2: JIS B 8370: Pneumatic system axiom.
CAUTION : Operator error could result in injury or
equipment damage.
WARNING : Operator error could result in serious
injury or loss of life.
DANGER : In extreme conditions, there is a
possible result of serious injury or loss of life.
WARNING
1. The compatibility of pneumatic equipment is the respon-
sibility of the person who designs the pneumatic system
or decides its specifications.
Since the products specified here are used in various operating
conditions, their compatibility for the specific pneumatic system
must be based on specifications or after analysis and/or tests to
meet your specific requirements.
2. 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 operators.
3. Do not service machinery/equipment or attempt to
remove component 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.
(Bleed air into the system gradually to create back-pressure,
i.e. incorporate a soft-start valve).
4. Contact SMC if the product is to be used in any of the
following conditions:
1) Conditions and environments beyond the given specifica-
tions, or if product is 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 micron.

Tube connection (push-in fitting) (Fig 5)
Ensure that the end of the tube is cut square. Push the tube firmly into
the fitting until it stops. Pull back on the tube to ensure that it is
engaged.
Replacement of cylinder port fittings
The cylinder port fittings are of a cassette type for easy replacement
(except for VQ0000). The fittings are blocked by a clip inserted from
the top of the valve. Remove the clip with a screwdriver to remove fit-
tings. To replace, insert the fitting assembly until it strikes against the
inside wall and then re-insert the clip to the specified position.
Disconnection
Push down on the collet flange, hold down, and withdraw the tube.
Electrical connection, plug lead only (plug connector) (Fig 4)
Push the connector onto the pins of the solenoid valve in a straight
line, ensuring that the lip of the lever is securely positioned in the
groove of the solenoid cover.
Disconnection (Fig 4)
Press the lever against the connector and pull the connector in a
straight line away from the solenoid.
NOTE
Plug-in units are factory pre-wired to specification (Fig 8).
Electrical disconnection D-sub connector (Fig 8)
Loosen the two captive screws 1, pull off the connector 2.
Electrical re-connection of D-sub connector (Fig 8)
Insert connector 2into the body 3.
CAUTION
Ensure that the connector enters directly onto the pins in the body.
Tighten the two retaining screws 1.
Electrical dis-connection flat cable connector (Fig 11)
Lift the two clamps 1outwards from the connector 2.
Remove the connector 2out of the body 3.
Re-fitting is the reverse of the above.
Wiring
Ensure that control wiring is separated from power wiring to prevent
noise generation.
Manual override
WARNING
Exercise extreme CAUTION when operating solenoid valve manual
overrides as connected equipment will commence operation.
Push non-locking type (Fig 6)
Push down on the manual override button 1until it stops (ON). Hold
this position whilst carrying out function checks. Release the manual
override button and the override will re-set to the (OFF) position.
Push locking type manual override (Fig 6)
Push down on the manual override button, using a small screwdriver
until it stops. Turn the button through 90° clockwise to lock. (180°
VQ0000).
CAUTION
In this position the override will be mechanically 'locked' in the ON
position.
Un-locking
Turn the manual override using a small screwdriver through 90° (180°
VQ0000) anti-clockwise. Remove the screwdriver and the manual
override will re-set.
Raised button type locking override (Fig 6)
Push down on the raised button until it stops.Turn the button through
90° clockwise by hand.
CAUTION
In this position the override is mechanically 'locked' in the ON
position.
Un-locking manual override
Turn the raised button through 90° anti-clockwise by hand. Release
the button and the manual override will re-set to the OFF position.
Lamp and surge voltage suppressor (Fig 7)
All solenoid valves are equipped with lamp and surge protection as a
standard feature. The indicators are positioned on one end of the
valve, for both single and double solenoid types. The colours of the
indicator lamps match the colours of the manual override buttons.
D-sub connector/flat cable connector/terminal block
Wiring specification (Fig 12)
With the A side solenoid of the 1st station, as No. 1 (i.e. connected to
No. 1 terminal), wires are connected in the order indicated by the
arrow in Fig 12.
NOTE: No terminal should be left vacant.
Maintenance
WARNING
Before carrying out any maintenance work ensure that air and power
supplies are ISOLATED.
