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.

Note 1: As per JIS B8375-1981 (Coil temperature; 20°C, without surge voltage suppresser at rated voltage).
Note 2: Shock resistance - - - -No malfunction from test using drop impact tester, to axis and right angle and armature, each one time when
energized and de-energized.
Vibration resistance - - No malfunction from test with 8.3 to 2000Hz 1 sweep, to axis and right angle direction of main valve and
armature, each one time when energized and de-energized. (Primary value).
Electrical connection L/M type plug connector (Fig 2)
1. Insertion: Push the connector straight onto the pins of the sole-
noid making sure the lip of the lever securely “locks” into the
groove of the solenoid cover.
2. Removal: Press the lever against the connector housing and pull
it away from solenoid.
Connection/Disconnection of socket to connector (Fig 3)
Connection
Insert a socket complete with lead attached into square hole (marked
+, -) of connector. Push firmly until hook engages. Confirm engage-
ment by lightly pulling the lead.
Disconnection
To disconnect socket and lead assembly from the connector insert a
pin of approximately 1mm diameter into the hole in the connector,
located on the opposite side to the lever. Depress the hook on the
socket and withdraw. If the socket is to be re-used, gently spread the
hook of the socket.
Surge voltage protection circuit (Fig 4)
DC
Ensure that connections are made to the (plus) and (minus)
terminals on the connector.
Pre-wired solenoids will have red leads connected to the +(plus) ter-
minal and black leads connected to the -(minus) terminal.
WARNING
Incorrect connection may result in failure of diode or switching element.
Leakage voltage (Fig 5)
Note that when using a C-R device (surge voltage suppresser) for con-
tact protection, the voltage leakage may increase due to the current
leakage flowing through the C-R device.
Suppress residual voltage leakage as follows:
DC Coil 3% or less of rated voltage
Wire each valve on the manifold to integral printed circuit board.
External connection is made by flat cable via a 26 pole MIL type
connector.
Lubrication
These valves have been lubricated for life during manufacture and as
such require no further lubrication.
CAUTION
However, if a lubricant is to be used with a rubber seal type, a turbine
oil type #1, (ISO VG32) should be used. Continuous lubrication must
be carried out as the original lubricant will be washed away.
Manual override operation (Fig 8)
WARNING
Exercise EXTREME CAUTION when operating a solenoid manual over-
ride as connected equipment will commence operation.
Ensure all safety measures are in place.
Non-locking push type (Fig 8)
1. Push down the manual override button (Orange), until it stops,
using a small-bladed screwdriver.
2. Hold this position for the duration of the check (ON position).
3. Release the button and the override will re-set to the OFF
position.
Slotted locking type (Fig 8)
To lock
1. Insert a small-bladed screwdriver into the slot and push the man-
ual override down until it stops.
2. Turn the override through 90° in the direction of the arrow (ON
position).
3. Remove screwdriver.
WARNING
In this position the manual override is in the locked “ON” position.
To unlock
1. Insert small-bladed screwdriver into the slot of the manual
override.
2. Turn the screwdriver 90° in the reverse direction.
3. Remove the screwdriver, the manual override will re-set to the
“OFF” position.
Piping (Fig 9)
1. Ensure that the pipe is clean of swarf, cutting oil, dust etc.
2. When screwing the pipe of fitting into a port ensure that any
sealant is prevented from entering the valve. When using sealing
tape leave the first 1.5~2 threads free of tape.
Tightening thread portion
When installing fittings etc., tighten thread portion as follows:
1) M3, M5
1 In the case that you use SMC fittings etc., please tighten thread
as follows: First tighten it by hand, then give it an additional 1/4
turn for M3, 1/6 turn for M5 with a wrench. And in the case of
minutia fittings, tighten it by hand, then give it an additional 1/4
turn with wrench. Also universal elbow and universal tee which
have gaskets at two points, give it an additional 1/2 turn with the
wrench. Note: Excessive tightening may damage the thread por-
tion or deform the gasket to cause air leakage. Also insufficient
tightening may have the thread loosened or cause air leakage.
2 In the case that you use fittings except SMC, please confirm the
instruction by that company.

Installation
WARNING
Ensure all air and power supplies are ISOLATED before commencing
installation.
Do not install these valves in explosive atmospheres.
If these valves are exposed to water or oil droplets, ensure that they
are protected.
If it is intended to energise a valve for an extended period, please con-
sult SMC.
If air leakage causes associated equipment to malfunction cease using
valve and inspect for cause.
Check fixings while pressure and power are applied. Initial function
and leakage tests should be performed after installation.
Install only once safety instructions have been read and understood.
Coating. Warnings or specifications indicated on the product should
not be erased, removed, or covered. If paint is applied to resin parts it
may have an adverse effect due to solvent attack.
Should coating of valve be required, contact SMC for advice.
