Attach the head expansion board with the screws.
Attach the head expansion board with the two M3 screws used to
mount the cover.
To remove the head expansion board, reverse the steps above.
■ Assigning the head ID No.
The head ID No. is assigned according to the position of the
connector to which the head is connected.
■ Mounting the I/O connector for expansion units
For the input and output of the GT2-E3N/E3P, use OP-84456 (MIL
socket connector 30-pin) sold separately.
For the information on how to assemble the connector and how to
connect the power cable, refer to "GT2-100 Series User's Manual".
● Pin arrangement of I/O connector
For details about the I/O circuit, refer to page 15 of this instruction manual.
Valid ID Setting
On the GT2-100 Series, the expansion unit head ID No. is pre-
assigned. When turning on the power for the first time or changing the
number of connected sensor heads, set the valid ID.
■ Default values of the valid ID
The initial value of the valid ID setting varies depending on the
number of head expansion boards.
• When using the unit with the initial values, connect the maximum number
of sensor heads. When the number of the connected sensor heads is
less than the valid number of connected units, "ErH (head connection
error)" appears along with the ID to which no sensor head is connected.
• When the number of the connected sensor heads is less than the
maximum number of connected units, change "27. id (Valid ID
Setting)" in the additional function setting mode.
■ Changing the valid ID

NOTICE
• Apply tightening torque of 0.5 to 0.7 N•m
• Be sure to attach the head expansion board with
screws.
• Be sure to connect the head expansion boards
sequentially from the upper slot.
Reference • The assigned head ID No. cannot be changed.
• Be sure to connect the sensor heads sequentially
without skipping a connector. If the head expansion
board has a connector to which no sensor head is
connected, disable the unused connector in the
valid ID setting.
• The sensor heads exceeding the IDs set in the valid
ID setting cannot be recognized.
