1 Safety Precautions
• Before using the device, thoroughly read the following safety precautions and use as directed.
• Hazards and levels of danger that can occur due to incorrect handling are classified by the following symbols.
Warning Incorrect handling can result in death, serious injury, etc.
Caution Incorrect handling can result in injury or damage to the building or its contents.
• After reading this manual, keep this manual for future reference. When the device is reinstalled or repaired, give this
manual to those who provide these services. When the user changes, make sure that the new user receives this manual.
WARNING
Ask your dealer or a qualified technician to install the device.
Improper installation by the user may result in electric shock or fire.
Properly install the device on a surface that can withstand the
weight of the device.
Device installed on an unstable surface may fall and cause injury.
Only use specified cables. Securely connect each cable so
that the terminals do not carry the weight of the cable.
Improperly connected or fixed cables or short-circuited cables may
produce heat and/or result in fire.
Do not make any modifications or alternations to the device.
Modifications or improper repair may result in electric shock or fire.
Consult your dealer for repair.
CAUTION
Do not install the device where a flammable gas leak may
occur.
If a flammable gas leaks and piles up around the device, it may be
ignited and/or explode.
Do not use the device in an unusual environment.
If the device is installed where a large amount of oil (including machine
oil), steam or sulfidizing gas is present, this environment may lead the
device to a remarkable drop in performance or damage its parts.
When installing the device in a hospital, communication station, or similar place, provide sufficient protection against noise.
An inverter equipment, private power generator, high-frequency medical equipment or radio communication equipment may interfere with the
normal operation of this device. On the other hand, the device may affect such equipment by creating noise that disturbs medical treatment or
image broadcasting.
Properly install the device according to the instructions in this
manual.
Improper installation may result in electric shock or fire.
Have all electrical work performed by an authorized
electrician according to the local regulations and instructions
in this manual.
Power supply circuit capacity shortage or improper installation may
result in electric shock or fire. Ask your dealer or a specialist when
performing an electrical work.
Do not move or reinstall the device by yourself.
Improper installation may result in electric shock or fire. Consult
your dealer or a specialist when moving or reinstalling the device.
Do not install the device where a large amount of steam rises,
such as in the bathroom or kitchen.
Avoid installing this device where dew condensation occurs. If the
device is installed in such places, it may result in electric shock or
malfunctions.
Do not install the device where acidic or alkaline solutions or
chemical sprays are used frequently.
Doing so may lead to electric shock or malfunctions.
Do not put tension on the power supply wires.
If tension is put on the wires, they may break and result in
excessive heat and/or fire.
Do not immerse the device in water.
Doing so may lead to electric shock or malfunctions.
Do not install the device where the temperature may become
more than 40°C [104°F] or less than 0°C [32°F] or it will be
subjected to direct sunlight.
If the device is installed in such place, it may result in deformation
or malfunctions.
Use standard products with the proper current capacity.
The use of non-standard wires may result in current leak,
excessive heat, and/or fire.
Do not touch the main board with hands or tools. Prevent dust
from forming on the board.
Doing so may result in fire or malfunctions.
Do not apply an AC power source. The maximum applied
voltage for the device is 24 VDC.
Using the incorrect voltage may result in device failure, ignition,
and/or fire.
2 Device Capabilities
This device can be used in combination with a system controller to operate/stop general-purpose equipment, as well as to
monitor the operating status and error status.

* This figure omits the power supply line and only shows the transmission line.
Note:
• For the shield ground of the M-NET centralized control line, use single-point grounding at the power unit for the transmission
line.
However, when supplying electric power to the M-NET centralized control line from the R410A series outdoor unit without using
a power supply unit for the transmission line, use single-point grounding at the TB7 of that outdoor unit.
Furthermore, when connecting this device to the M-NET indoor control line, use grounding at the TB3 for each outdoor unit
system.
• If this device is connected to the M-NET indoor control line and the outdoor unit is down because, for example, the power supply
is interrupted for servicing or there is a failure, the DIDO controller cannot be controlled from the system controller.
• Controlling the system remote controller, ON/OFF remote controller, and schedule timer is only possible with channel 1 of a
standard terminal.
• When G(B)-50A is connected, monitoring control can only be performed from G(B)-50A Web or TG-2000A. Monitoring control
cannot be performed from the system remote controller, ON/OFF remote controller or schedule timer.

7-3. Connecting the Signal Lines
• Separately procure the relay, power supply for the relay, terminal block, and cable locally.
• The maximum wire length is 100 m. However, since the use of long wires makes the device susceptible to noise, using
wires shorter than 10 m is recommended.
• Connect another relay within 10 m from DIDO controller to extend the input line.

Caution:
• When using X1, X2, X3, X4, Y1, Y2, Y3 and Y4 relays, select ones that satisfy the following specifications.
Operating coil
Rated voltage: 24 VDC (Built-in diode)
Power consumption: 0.9 W or less
(*1) Be sure to use the ones with the voltages rated above. Exceeding the rated voltage may affect the ON/OFF of other outputs.
(*2) When using a separate power supply for this device, connect GND of the power supply to V– of CN16 of the terminal block
of this device.
(*3) Use a relay with a withstanding voltage of at least 2000 VAC between the coil and contact.
Otherwise, there is the likelihood of an electric shock or fire.
• Select a contact with a minimum applicable load of 1 mADC or less for the input contact.

error occurs
*1: If LED11 flashes quickly three times in any of the display states, it is an indication that an error input has been detected on one of channels 3 to 6. To
confirm the details, turn ON both of SW03-6 and 7 and select to "(3) Error Input Status Display of Channels 3 to 6".
*2: If a communication error occurs in any of the display states, switch to "Communication Error Status Display". Changing SW03-8 from ON to OFF masks
the "Communication Error Status Display" for 10 seconds so that the input/output status display set with SW03-6 and 7 can be confirmed.

10-2. Communication Error Status Display
If a communication error occurs, a 4-digit error code will be repeatedly displayed according to the steps shown below.
Communication error status display consists of the following 10 steps. This operation is performed repeatedly to indicate the
4-digit error code for the communication error.
Furthermore, changing SW03-8 from ON to OFF masks the "Communication Error Status Display" for 10 seconds so that
the input/output status set with SW03-6 and 7 can be displayed.

11 Test Run
Use the following procedure to confirm operation of the system.
(1) Configure the settings of this device and the system controllers while referring to "8 Initial Setting Procedure".
(2) Perform an operation from a system controller and confirm whether a connected general-purpose device can be operated normally.
(3) In the case of using contact inputs
(a) Change the operate/stop status of the connected device and confirm whether the operation status is displayed on the system
controller.
(b) Generate an error on the connected general-purpose device and confirm whether the error is displayed on the system controller.
(4) In the case of using error interlock stop outputs
(a) Generate an error on the connected device and confirm that "Stop" is output from a contact output.
If there is a problem, check the wiring and settings.
For details on configuring settings, refer to "8 Initial Setting Procedure" and "9 Switch List".
