Use fingers to insert the connector into the
pin, push it in until the lever claw latches
onto the protruded section of the connector
housing, and complete the connection.
To remove the connector, squeeze the lever
along with the connector, lift the lever claw
up from the protruded section of the
connector housing, and pull it out.

Non-locking type
To operate the manual override, press it all
the way down. For single solenoid, the valve
works the same as when in the energized
state as long as the manual override is
pushed down, and returns to the normal
position upon release.
For the double solenoid, pressing the manual
override on the 12(S1) side switches the
12(S1) to enter the energized position, and the
unit remains in that state even after the
manual override is released. To return it to the
normal position, operate the manual override
on the 14(S2) side. This is the same for the
solenoids 14(S2).

Crimping of connecting lead wire and contact
To crimp lead wires into contacts, strip off
4mm [0.16in.] of the insulation from the tip
of the lead wire, insert it into the contact,
and crimp it. Be sure to avoid catching the
insulation on the exposed wire crimping
section.

Cautions: 1. Do not pull hard on the lead wire.
2. Always use a dedicated tool for
crimping of connecting lead wire
and contact.

Manufactured by Sumiko Tech, Inc.
Crimping tool: Model F1-702062
Manufactured by Sumiko Tech, Inc.
Attaching and removing contact and connector
Insert the contact with lead wire into a plug
connector □ hole until the contact hook
latches on the connector and is secured to
the plug connector. Confirm that the lead
wire cannot be easily pulled out.
To remove it, insert a tool with a fine tip
(such as a small screwdriver) into the
rectangular hole on the side of the plug
connector to push up on the hook, and then
pull out the lead wire.
Cautions: 1. Do not pull hard on the lead wire. It
could result in defective contacts,
breaking wires, etc.
2. If the pin is bent, use a small
screwdriver, etc. to gently straighten
out the pin, and then complete the
connection to the plug connector.

※Illustration shows the 110 series.
Locking type
To lock the manual override, use a small
screwdriver to push down on the manual
override all the way down and turn it 45
degrees. Either turning direction at this time
is acceptable.
When locked, turning the manual override
from the locking position releases a spring
on the manual override, returns it to its
normal position, and releases the lock.
When the manual override is not turned, this
type acts just like the non-locking type.
TURN
PU
SH
※Illustration shows the 240 series.
Cautions: 1. The 240 series valves are pilot type
solenoid valves. As a result, the
manual override cannot switch the
main valve without air supplied from
the 1(P) port.
2. Always release the lock of the locking type manual overrides before
commencing normal operation.
3. Do not attempt to operate the
manual override with a pin or other
object having an extremely fine tip.
It could damage the manual
override button.
4. Do not turn the adjusting knob
more than needed. It could result in
defective operation.

Cautions: 1. For the 1(P) port piping, use a size
that matches the manifold’s piping
connection port. Insufficient flow rate
or pressure could result in defective
valve operation or in insufficient
actuator output.
2. When installing piping or mufflers to
the 3(R2) and 5(R1) ports, ensure
there will be minimum exhaust
resistance. On rare occasions,
exhaust from valves can interference
with other valves and actuators.
3. When a multiple number of valves
operate simultaneously on a multiunit manifold, or when the manifold
with valves is used at high frequency,
supply air from the 1(P) ports on both
ends, and exhaust air from the 3(R2),
5(R1) ports on both ends.
4. In bottom ported manifolds (B type
and BW type), use of the bottom
1(P), 3(R2) and 5(R1) ports can
prevent flow rate or pressure
shortages, or exhaust interference.

Stacking unit order
Piping
The 1(P) port, 3(R2) port, 5(R1) port and PR
port are on both ends of the manifold, and
piping direction can be selected depending on
the mounting location. At shipping, the ports
on one side are plugged. Remove the plugs
and then use sealing tape or another sealing
agent to tighten in place.

If stacking part is required due to the addition or replacement of manifold units, use the following order codes to

Stacking
The A Type, B Type, AW Type and BW Type
manifolds are the stacking type, for flexible
addition or reduction of units.
●Assembly instructions
240M□A and 240M□B
Loosening the joint mounting bolts (hexagon
socket head bolts) w on both ends and
removing the joint q lets the stations be
separated.
To add units, position the O-rings y and u
and gasket t in the stacking unit stations,
install the joint, and tighten the joint
mounting bolts.
240M□AW and 240M□BW
Loosen the set screw on the terminal cover,
remove the terminal cover o and
connection cover !0, and pull out the
terminal block i.
Loosening the joint mounting bolts on both
sides and removing the joint lets the stations
be separated. To add units, first position Orings and gaskets in the stations to be
added, install the joint, and tighten the joint
mounting bolts. Then, fit the terminal block,
secure the terminal cover in place with
mounting screws, and fit the connection
cover.
DIN connector
Mounting and removing valves
With the plug-in type, valves can be
replaced while leaving the air piping or
electrical wiring in place.
Loosen the 3 valve mounting screws, and
pull the valve straight out. To mount the
valve, align the valve plug over the socket of
the sub-base or manifold, and fit it straight
in. Then tighten the valve mounting screws
to secure it in place.
Socket
●Piping port location
With the 1(P) port on both ends and the
bottom surface, the 4(A) and 2(B) ports on
the side and bottom surfaces, and the 3(R2)
and 5(R1) ports on both ends and the
bottom surface, piping is allowed in any
location. Use the plugs provided with the
manifold, with sealing tape or another
sealing agent, to block off the unused ports.
Port isolator
Port isolators on the 1(P), 3(R2) and
5(R1) ports can be used to separate them
from adjacent stations, to allow supply of
different pressures, or to prevent exhaust
interference.
Port isolators can be fitted and assembled
between stations in place of the O-rings y
to separate the 1(P), 3(R2) and 5(R1) ports
from adjacent stations. For stations split by
port isolators, plumb the 1(P), 3(R2) and
5(R1) ports on the bottom.
Block-off plate
To close up the unused stations, use a
block-off plate (order code: -BP).
●Solenoid with DIN connector
When de-sheathing (outer sheath of the
cabtyre only), pay attention to the outlet
direction of the lead wire. The cover will be
easy to mount when the lead wire on the outer
side of the terminal cover interior is set to
about 8mm [0.31in.] longer than the inner side.
Without stripping off the sheath, insert the lead
wire until it contacts the lead wire stopper on
the terminal body, and then place the contact
from the upper side. Then use pliers to press
the lead wire further to ensure that the
contacts are firmly holding the core wire.

Wiring instructions
Wiring instructions
In the plug-in type, the terminal block and
solenoid are connected by a plug and
socket. Loosen the terminal cover mounting
screws, remove the terminal cover, and
then pull out the terminal block and connect
it. Fit the connected terminal block into the
sub-base or manifold, mount the terminal
cover, then secure the mounting screws in
place.
Connect the single solenoid leads to the
No. 2 (＋, −) terminal.
In the double solenoid, the No.1 (＋, −)
terminals are connected to the valve’s
solenoid 12 (S1), and the No.2 (＋, −)
terminals to the solenoid 14 (S2). For DC
models, pay attention to the polarity. While
a wrong in polarity will not cause a short
circuit, the valve will not operate.
For the terminal, use the round terminal
JIS2805 R type 1.25-3 or equivalent.
To order the terminal block and other parts
for adding units, see the manifold parts
order item on p.657. A collective common
type manifold that uses crossover contacts
can also be manufactured. Consult us.

cylinder’s max. speed operating time t 2.
When a cushion is used, add the cushioning time
t3, to the above calculations. The standard
