To use this product safety, basic knowledge of pneumatic equipment,
including materials, piping, electrical system and mechanism is
required (to the level pursuant to JIS 8370 Pneumatic System
Rules).
We do not bear any responsibility for accidents caused by any
person without such knowledge or arising from improper operation.
Our customers use this product for a very wide range of
applications, and we cannot keep track of all of them. Depending on
operating conditions, the product may fail to operate to maximum
performance, or cause an accident. Thus, before placing an order,
examine whether the product meets your application, requirements,
and how to use it.
This product incorporates many functions and mechanisms to
ensure safety. However, improper operation could result in an
accident. To prevent such accidents, read this operation manual
carefully for proper operation.
Observe the cautions on handling described in this manual, as well
as the following instructions:
PRECAUTIONS
PRECAUTIONSPRECAUTIONS
PRECAUTIONS
 Incorrect address settings of serial transmission slave stations could
cause the solenoid valve and the cylinder to malfunction.
 For operation if serial transmission slave stations, read the
communication system operation manual carefully.
 Do not touch electric-wiring connections (exposed live parts): this
will cause an electric shock. During wiring, keep the power off. Also,
do not touch these live parts with wet hands.

This product does not meet the surge immunity requirements specified
in EN61000-4-5 for CE marking. Please provide appropriate protective
measures against lightning surges on the device side.

When the valve power is turned on (i.e., at power-up),the valve lamp
may light up momentarily. However, the valve itself is not turned on
or off as a result of this.

１． PRODUCT
１．１ General outline of the system
1) MW4G※2-T8G※
This solenoid valve system is equipped with a remote I/O station(NW4G※
2-T8G ※), the CC-Link open field network system. (This is specified by
CC-Link Partner Association. :hereafter referred to as CLPA)
The following features are provided.
(1) It helps to curtail wiring man-hours as it requires twist pair cables only to
connect it with PLC.
(2) This slave station is an environment-proof slave station applicable to the
protection structure IP65 (dust-proof and jet-proof type).
(3) Upper and side wiring directions are provided, ensuring reduction of the
installation space.
(4) The power supply for the slave station is separated from that for the valve,
ensuring easy maintenance work.
(5) The energized status of the valve power supply can be checked by using the
master station through the communication. (Detection function, such as fuse
blow-up)
(6) The slave station output status, if the communication error occurs, can be
set using the switch (holding or all points OFF).
2) CC-Link
The CC-Link is Open field network system for FA including remote I/O devices
(Sensor and valve, etc.) and intelligent devices (high-speed counters, inverters,
etc.), can be configured with reduced wire connections. Moreover, the user can
create programs that control these devices installed away from the master
station without being aware of the communication protocols.
The CC-Link system has following features:
(1) 10Mbps network, the fastest network in the industry, is applicable to a
sensor and large capacity data communication requiring the high-speed
response.
(2) Remote control handling the bit data and data communication handling word
data (analog) can be performed at the same time. The communication is also
stable at a high speed.
(3) “n : n” cyclic transmission can be performed between the controllers,
ensuring easy distributed control.

1) Monitor lamp
Various LED lamps are installed in front of station to aid visual verification of
operational conditions. Each function is printed on the sheet made of resin.
Make use of them during maintenance works or for verification of operation.
Name of LED Content of indication
PW1 Lit when unit power is ON.
PW2 Lit when valve power is ON.
SD links while Data being output.
RD links while Data being input.
L RUN
This checks whether or not the slave station correctly exchanges the data with the master station. Lit
when data is received normally from the master station. Goes off when data is absent for a preset period
of time.
L ERR
Lit when a transmission error (CRC error) is detected.
Goes off after a preset period of time. (The RUN lamp is also off.)
Lit when the user specifies a value out of range when setting the station number or transfer rate.
(When
the setting is corrected and the power is turned ON again, the lamp will go off.)
links when the station number or transfer rate setting is modified during operation.
(The RUN lamp is lit. The slave station starts operation with the station No. setting and transmission
speed setting made when the power is turned ON.)
2) Setting switch
This switch is used to set a station No. allocated to the slave station and a
transmission speed.
Name of switch Content of setting
Station number setting Sets the slave station numbers within the bounds of 01-64.
Transfer rate setting Sets the transfer rate between the master and slave stations. A value ranging
from 0 to 4 is set.
Setting of output status in case of an
error Specify whether to hold (HDL) or clear (CLR) the output when an error occurs.
 Before changing the switch positions, be sure to cut the power.
 Tighten the switch cover screw with a specified tightening torque (0.3 to 0.4N･m). If the screw is
tightened insufficiently, the protection structure may not be kept.
 Keep the cover closed except when you have to change switch positions or reconnect wires. If
you keep the cover open unnecessarily, foreign matter may enter the circuit board causing an
unexpected failure, or the cover may be broken by accidental contact. While the cover is open as
you change switch positions or reconnect wires, be careful not to cause the entry of foreign
matter.

•
Refer to User’s manual for the master station concerning to transmission delay
time. The transmission delay within the entire system depends on the scan time
achieved by the PLC unit and on other devices included in the network.
• Solenoid valve responding time, of course, varies depending on model.
It is advisable of referring to valve specification.
• As for OFF time, there is another delay factor of approx. 20ms due to flywheel
diode being used for surge absorbing circuit to valve slave station.
• Connect the power supply cable and signal cable correctly within the
specifications so that any incorrect wiring is not performed.
• Pay special attention so that any tensile force or impact is not applied to the
power supply cable and signal cable.
• efore turning ON the power, make sure that the various connection cables and
connectors are connected firmly.
• Disassembly, modification, and/or repair made by the customer may cause a
trouble or malfunction. Never attempt to disassembly, modify, and/or repair the
unit.
• Many precision devices are mounted inside the unit. Do not drop the unit or
apply vibration or impact to the unit.
• If any connector is disconnected or connected with the electric power supplied,
this may cause a trouble or malfunction. Do not disconnect or connect any
connector with the electric power supplied.

The switches are used for different kinds of setup: setting the station number,
setting the transfer rate, specifying whether to hold or clear the output during
an error. Since different switches are used for different kinds of setup, you must
correctly identify the switch to be used. efore changing the switch positions, be
sure to cut the power.
