Fig. 13 Separate power supplies for the system and field supply
Do not connect the protective earth connection PE of RS422 extension terminal with the
supply ground of system respectively field supply. As a result, the bus communication is
disrupted or the RS422 extension terminal damaged.
Connect the inputs laser and GND to the RS422 extension terminal in order to
switch on the laser beam of the connected sensors, see Fig. 13 .
A connection of the input to GND using a button or a transistor (NPN - Open collector) is
sufficient for starting.
The laser beam of the sensors, connected to the RS422 extension terminal, is switched
off for open inputs.
Connect the controller (
EtherCAT
) with an EtherCAT bus coupler. Use a LAN cable
with RJ-45 connectors.

to the protective earth
connection of mains
power.
