Operation not anticipated may cause damage of the machine and the product.
To prevent the malfunction by the noise, the AL-
communications cable recommends
QAUTION

Core connection of AL-
communications cable
( )
Ⅱ
Please install the core in the master side. And, the personal computer system including the AL -
communication

is made to operated with stability.
The core is prepared by our company.
Please refer to the "connection/other" manual.
2 Connection of terminator
( )
Please connect terminator CB-54/R
with the slave unit arranged on the AL-
communication network edge.
(
)
Ⅱ
Please do not connect the terminator with other equipment.
There is no problem even if AL-
communications or the terminator are connected with either of J1, J2.

Power supply and slave power supply for communication
( )
The AL-
communication power supply of each slave unit is supplied from the AL-
master through the
Ⅱ
Ⅱ
communications cable so that the entire AL-
communication network should not become unstable when the
Ⅱ
power supply on each slave unit side is intercepted.
The reconnection of communications can be done by executing Environment-function to the master when the power
supply of the main unit on the slave side is obstructed.
Moreover, 2CD-7713v1/GDB5F40 can independently intercept driving power supply with the controller power supply
maintained for the safety of the equipment.
