Setting addresses for each air conditioner
To control and communicate with the air conditioners, a DIII-NET address needs to be set for each air conditioner.
For detailed instructions on how to set addresses, refer to the
“DGE601A52 Installation Manual (3P581074-2)” or
“DGE601A72 Installation Manual (3P581074-6)”.
The installation work of DGE601A53 is complete.

Quick Operation Guide
5.1 Restarting the unit
The DGE601A53 can be restarted by pressing the
[RESET//] button.
Operate the
[RESET//] button using a thin rod or similar item.
Only the slot whose
[RESET//] button has been pressed will restart.
CAUTION
Do not perform the operation with a pointed item. Doing so may result in malfunction.

A
Pulse width: 20 to 400 ms
B
Pulse interval: 100 ms or more
CAUTION
•
The contact connected to the contact input terminal must be capable of handling 10 mA at 16 V DC.
•
If an instantaneous contact is used for triggering an emergency stop, use one that has an energisation
time of 200 ms or more.
NOTE
Once the emergency stop input signal is turned on, all air conditioners stop and do not restart until the emergency
stop input is cleared.

3.1.4 Precautions for using multiple centralized controllers
If multiple centralised controllers are connected on the DIII-NET network, the
“MAIN (MASTER)” and “SUB
(SLAVE)” relationship for those controllers.
Set only one of those controllers as MAIN (MASTER), and the other controllers as SUB (SLAVE).
<DIII MASTER>
The
[DIII MASTER]
switch is located on the front face of the DGE601A52/
DGE601A72. The switch in the
[ON] position sets it as “MAIN” and the
switch in the
[OFF] position sets it as “SUB”.
3.2 Connecting an emergency stop input device or electric energy meters
3.2.1 Terminals location and schematic connection diagram
Connect the contact input lines or pulse signal lines to the
[i1] [i2] [i3] [i4] [CM] terminals of Di located on the upper
part of the front face.

3.1.2
Wiring specifications
•
Cable type: 2-core vinyl-insulated vinyl-sheathed cable/vinyl cabtyre cable or 2-core shielded cable
•
Core thickness: 0.75-1.25 mm², AWG 18-16
WARNING
•
Do not use multicore cables with 3 or more cores.
•
When using a shielded cable, connect only one end of each shield wire to the earth.
•
The maximum wire distance must be kept to 1000 m (3280 ft.) or less, and the total wire length must be
limited to 2000 m (6561 ft.) or less.
However, when using a shielded cable, the total wire length must be kept to 1500 m (4921 ft.) or less.
3.1.3 Address setup and termination resistor
For each DGE601A53, a unique address needs to be set.
In case of connecting to the DGE601A51/DGE601A71, set a number between “3” and “8”.
In case of connecting to the iTM, set a number between “2” and “8”.
Use the
[PORT]
switch located on the front face of each DGE601A53 to set an address. Moreover, the termination
resistor needs to be set for the DGE601A53 which is the furthest from the DGE601A51/DGE601A71 or iTM.
To set the termination resistor, change the position of the
[TERM] switch located on the front panel of the DGE601A53
to the
[ON] position.

NOTE
If both the
[ALV] and [ALARM] LEDs are lit when powering on the unit after installation, then probably something
went wrong with the PORT (address) assignment:
•
You set an invalid PORT address. (In case of DGE601A51/DGE601A71,
“0”, “1”, “2”, and “9” are not allowed,
and in case of iTM,
“0”, “1”, and “9”
are not allowed.)
•
You used the same PORT (address) twice.
Check and correct the PORT (address), then power on the DGE601A52/DGE601A72 again and restart.
Check the status of the
[ALV] and [ALARM] LEDs.
