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.

CAUTION
Leakage voltage
When a C-R device (surge voltage suppressor) is used for the
protection of the switching device, be aware that leakage voltage will
be increased by passing this leakage through a C-R device.
Suppress residual leakage voltage as follows:
DC coil: 3% or less of rated voltage
Solenoid manual override (Fig 8 and Fig 9)
WARNING
Exercise extreme CAUTION when operating solenoid manual overrides
as connected equipment will commence operation.
Push non-locking type (Fig 8)
1 Push down on the manual override button (Fig 8) until it stops ON.
2 Hold this position whilst carrying out function checks.
3 Release the manual override button and the override will re-set to
the OFF position.
Push locking type (Fig 9)
1 Push down and turn the manual override button (Fig 9) clockwise
using a small slotted screwdriver until the slot is opposite the
locked position.
2 Withdraw the screwdriver.
WARNING
In this position the manual override is mechanically locked ON.
Unlocking (Fig 9)
1 Insert screwdriver into the override slot, push down and turn anti-
clockwise until the slot is opposite the unlock position.
2 Remove the screwdriver and the manual override will re-set to the
OFF position.
Maintenance
WARNING
Before carrying out any form of maintenance ensure all air and power
supplies are isolated.
Removing a valve from the base (Fig 10)
1 Disconnect the electrical connector 1(Fig 10) (Also refer to Fig 6).
2 Remove the valve holding down screws 2 and retain) (Fig 10) .
3 Lift off the valve from the base.
4 Retain the gasket 3(Fig 10) .
Refitting a valve to a base
1 Refit the gasket 3 (Fig 10) ensuring correct orientation.
2 Replace the valve.
3 Refit the valve holding down screws 2 (Fig 10).
4 Torque the screws to the following figures:
SYJ300 0.12 N-m {1.2 kgf/cm}
SYJ500 0.45 N-m { 4.5 kgf/cm}
SYJ700 0.8 N-m { 8.0 kgf/cm}
Fitting blanking plate (Fig 11)
1 Remove valve as shown above (Fig 10).
2 Fit blanking plate gasket 3(Fig 11) .
3 Fit blanking plate 2Fig 11).
4 Fit blanking plate holding down screws 1(Fig 11).
5 Torque the screws to the following figures:
SYJ300 0.12 N-m { 1.2 kgf/cm}
SYJ500 0.45 N-m { 4.5 kgf/cm}
SYJ700 0.8 N-m {8.0 kgf/cm}

Rc(PT)1/4 12~14 (120~140)
Lubrication
The valve has been lubricated for life at manufacture and requires no
additional lubrication.
CAUTION
However, if a lubricant is to be used, a turbine oil type #1 (ISO VG32)
should be used. If a lubricant is used, continuous lubrication must be
carried out, as the original lubricant will be washed away.
Energisation time
The double solenoid valve must be energised for at least 0.05 seconds
to ensure proper operation.Low
Low temperature application
May be used down to -10° if the air is sufficiently free of moisture.
Please use an appropriate dryer to ensure dry air preventing the valve
from freezing.
Energising in a long run
For use of long run energising, its specifications should be consulted.
Tube connections - push-in fittings (Fig 4)
1 Ensure the tube 5is cut square.
2 Push tube 5into the body 7until tube stops.
3 Lightly pull tube 5back to ensure connection.
Tube disconnection (Fig 4)
1 Push collet in 1.
2 While holding collet in 1withdraw tube 5.
3 Release collet 1.
Connection of plug connector (Fig 5)
1 Push the connector in a straight line onto the pins of the solenoid
ensuring that the lip of the lever is securely positioned in the
groove of the solenoid cover.
Disconnection of plug connector (Fig 6)
1 Press the lever against the connector and pull the connector away
from the solenoid.
CAUTION
Do not exert excessive force on the wires as this may cause contact
failure.
Wiring specifications (Fig 7)
Ensure correct connection of the lead wires to (+) (positive) and
(-) (negative) indications on the connector. For non-polarity type the
lead wires can be connected to either one.
For DC voltages other than 12, 24 incorrect wiring will damage the
surge voltage suppressor circuit. (Incorrect polarity will cause
malfunction).
Solenoids whose lead wires have been pre-wired are red positive and
black negative.
