of the solenoid, making sure the lip of the lever securely
"locks" into the groove of the solenoid cover.
Removal—Press the lever against the connector housing
and pull it outward from the solenoid.

Operation of Manual Override
Use caution since manual override operation will operate
any connected actuators.
Non-locking push type
[Standard type]
Press in the direction of the arrow.
Push-locking slotted type
[D]
While pressing, turn in the direction of the arrow.
If you do not turn, the mechanism does not lock in position.
Note) A second manual override is located on the pilot
valve assembly. It is only available as a non-locking
push type. Simply depress in the direction of the
arrow shown to operate.
Common Exhaust Port for the Pilot and Main Valve
Pilot air is exhausted through the main valve body rather
than directly to atmosphere.
Suitable for applications where exhausting the pilot valve
to atmosphere would be detrimental to the surrounding
working enviroment.
For use in extremely dirty environments where there is
the possibility that dust could enter the pilot exhaust and
damage the valve. Ensure that the piping of exhaust air is
not too restrictive.
Locked positon
PUSH
LOCK
Series SYJ 3000 may be used as a N.C. or N.O 3 way
valve by plugging one of the A, B ports.
Be sure not to plug the exhaust ports. Can be used when
a double solenoid, 3 way valve is required.
Crimping connection of lead wire and socket
Strip 3.2 to 3.7mm of the lead wire ends, insert each
stripped wire into socket and crimp contact using
special crimping tool. Be careful that the outer insulation
of the lead wires does not interfere with the socket
contact part.
(Contact SMC for special crimping tool.)
Connection/Disconnection of socket with lead wire
Connection
Insert lead wire and crimped socket into square holes
(indicated as A,B, COM) of connector. Press the socket
in fully until the hook of the socket locks into the groove
of the connector housing. Confirm the locked position by
lightly pulling on the lead wire.
Disconnection
To remove the socket from the connector, pull out lead
wire while depressing the hook of the socket with a fine
screw driver (or similar). If the socket is to be re-used,
reposition the hook again.
