14.1 Wired synchronism
TX/RX arrangement for synchronism connection, regarding the IR section in the dual technology
barrier type.
The synchronisms are to be connected as per the above diagram.The SYNC OUT corresponds to the
part of the TX column and must be connected to the SYNC IN of the opposite RX column.
N.B.:It is also necessary to connect the power supply negative in common between the columns and
to use shielded cables (2x0.22mm²) for the synchronisms preferably separated from the power
supply, with the braid connected to the negative.
The synchronism connections between the columns can be made directly in the control unit or in a
branch junction box.By using a shielded cable with 2x0.22mm² cross section, connections up to 500 m
can be made. In the event of joints, the braid and shield connections must also be restored.
