Safety precautions
When designing and manufacturing devices using CKD products, the manufacturer is obligated
to ensure that the safety of the mechanism, pneumatic control circuit and/or fluid control circuit
and the system that runs the electrical controls are secured.
It is important to select, use, handle and maintain CKD products appropriately to ensure their
safe usage.
Observe warnings and precautions to ensure device safety. Check that device safety is ensured,
and manufacture a safe device.
1. This product is designed and manufactured as a general industrial
machine part. It must be handled by an operator having sufficient
knowledge and experience.
2. Use this product in accordance with specifications.
This product must be used within its stated specifications. In addition, never modify or
additionally machine this product. This product is intended for use in general industrial
machinery, equipment or parts. It is not intended for use outdoors (except for products
with outdoor specifications) or for use under the following conditions or environments.
(Note that this product can be used when CKD is consulted prior to its usage and the
customer consents to CKD product specifications. The customer should provide safety
measures to avoid dangers in the event of problems.)
Not intended for following applications:

If the product must be used under conditions that are different from the specified
conditions or if the product is to be used for a special application, consult CKD
before utilizing the product.
Before performing maintenance, turn off the power, cut off the compressed air
supply, and make sure there is no residual pressure.
Before increasing or decreasing the number of stations (valves) on the manifold,
turn off the power and release pressure.
Before disassembling or assembling the manifold, read this instruction manual
carefully with full understanding of its content.
Before performing electrical wiring, read this instruction manual carefully with full
understanding of its content.
Regularly perform daily and periodic inspections to correctly maintain product
performance.
Confirm the working voltage and polarity before wiring and turning the power ON.
Do not touch the electrical wiring connections (exposed live parts); as there is a risk
of electric shock. During wiring, keep the power OFF. Also, do not touch these live
parts with wet hands.
Before using the serial transmission slave unit, read the manual for the applicable
communication system carefully with full understanding of its content.
System components such as valves and cylinders could malfunction if the serial
transmission slave unit address setting is incorrect. Always check the address
setting before starting use.
This product does not meet the surge immunity requirements specified in
EN61000-4-5 for CE marking. Please provide appropriate protective measures on
the device side.
The valve status lamp may flicker momentarily when the valve power of the slave
unit turns ON (i.e., when the power voltage starts to rise). This will not cause the
valve itself to turn ON or OFF.

1. PRODUCT
1.1 General outline of the system
1) N4G*R-T8D**
The N4G*R-T8D** is a slave unit for 4G series which can establish connection to the DeviceNet
open field network system managed by Open DeviceNet Vendor Association, Inc. (or ODVA).
The N4G*R-T8D** slave unit has the following features:
(1) It is connected to the PLC with only a DeviceNet cable, allowing a significant reduction of
man-hours in wiring.
(2) It has separate power supplies for the network and the valve, ensuring ease of maintenance.
(3)When a communication error occurs, the slave unit output state can be set either hold or clear,
ON or OFF with a HC switch. With software setting mode, Explicit Message allows operation
being set for every one point at a communication error.
(4) The slave unit is mounted by inserting it into a slot on the manifold block and secured with just
one screw, allowing reduction of man-hours in maintenance.
(5) The slave unit is available in +COM or -COM output types and 16 or 32 output points, allowing
for use in a wide variety of applications.
2) DeviceNet
DeviceNet is a multi-bit, multi-vendor network that combines controls and data on a
machine/line-control level.
It is maintained and managed by ODVA (Open DeviceNet Vendor Association, Inc).
Note: Before using this slave unit, thoroughly read all relevant users’ manuals.
This instruction manual mainly describes N4G*R-T8D**.
For information on the master unit and slave units to be connected to the system, read the
manuals provided by their manufacturers.
For information on the manifold solenoid valves, read this instruction manual as well as the
manuals provided with the solenoid valves to fully understand their functions and
performance for their proper operation.
If you have any questions concerning the DeviceNet system, refer to the following website run by ODVA:

PRECAUTIONS
2. PRECAUTIONS
To correspond to the requirements of the relevant EC Directive, use AC/DC adapter (e.g., switching power
supplies) complying with EMC standards for the valve and communication power supplies.
Before turning the power ON or OFF, ensure the safety of the surroundings as the components in the system,
including the valve (cylinder), may move unexpectedly.
Refer to the user’s manual provided with the master unit concerning the communication delay time.
The transmission delay within the entire system depends on the scan time achieved by the PLC and on
other devices included in the system.
Solenoid valve response time varies by the model. Refer to the valve specification for the delay in
response time.
The time it takes for the solenoid valve to turn OFF is delayed by approximately 20 msecs since there is a
surge absorbing circuit incorporated in the slave unit.
Make sure the power cables and network cables are connected according to the specifications to avoid
any incorrect wiring.
Do not subject the power cables and network cables to tension and impact.
Before turning the power ON, make sure that all cables and connectors are connected firmly.
Never attempt to disassemble, modify, and/or repair the slave unit. Doing so may result in failure or
malfunction of the slave unit.
Do not drop, apply unusual vibration or impact the unit as the inside of the slave unit is a precision
construction.
Do not connect or disconnect any connectors while the power is being supplied. Doing so may result in
failure or malfunction.
Mold and rust can develop on the product if it is exposed to high humidity during transportation. Include
moisture absorbers and tightly seal the package.
Install the slave unit at least 200 mm away from high-voltage cables and power lines, or lay the
high-voltage cables and power lines in grounded metal tubings.

OPERATION
3. OPERATION
3.1 Switch settings
CAUTION:
Discharge static electricity that has built up on your body before touching
the slave unit. Otherwise, static electricity can cause damage to the slave
unit.
The slave unit will not identify the setting if the power is supplied. Make
sure the power of communication is turned OFF upon setting as they are
read into the unit only at power-up.
The cover on the slave unit is an easy-to-open one that requires only one
finger to flip it open. Keep the cover closed at all times except when
setting the switches. Otherwise, foreign matter may enter into the internal
circuit and cause unexpected failure, or the cover itself may get damaged.
Be extremely careful not to allow any foreign matter to enter the slave unit
when setting the switches.
Be sure not to touch the internal circuit board when setting the switches
as they are precisely built and can be damaged if mishandled.

OPERATION
3.4 Programming
This slave unit is treated as a slave unit device with 16 output points: T8D*1 and 32 output points:
T8D*2. There are 2 types of I/O data: output data transmitted from a master unit to a slave unit (with
16 output points: T8D*1 and 32 output points: T8D*2) and input data transmitted from a slave unit
device to a master unit.
This slave unit acts as an output device which transmits output data to valves after receiving it from
the master unit. Regardless of the model, the input data is transmitted to the master unit as 2 bytes of
reserved data.
When programming, refer to the PLC manufacturer’s manual, and to the tables shown below for I/O
mapping. The characteristics of this slave unit such as output status setting when error occurs, and
the +COM/-COM output specifications, have no relevance to the programming.
