SICK deTec4 Ex II 3GD - System 2; Direction of Transmission

Using reversed direction of transmission
T
he direction of transmission of the system " can be changed during mounting by
switching the positions of the sender and receiver. With reversed direction of mounting,
the receiver " is not affected by the infrared light from the sender !.

4.3.4.3 Combining beam coding and reversed direction of transmission
To prevent a mutual interference in the case of more than two neighboring systems,
be
am coding and reversed direction of transmission can be combined.

Figure 18: Trouble-free operation of 4 neighboring systems due to beam coding and reversed
dir
ection of transmission
In the figure, the beam coding of the systems arranged next to each other is different.
The direction of transmission of the systems arranged on top of each other is reversed.
This prevents the systems from interfering with each other.
4.3.4.4 Using a sender with a small scanning range
Overview
In or
der to prevent mutual interference of systems, a sender with a small scanning
range can be used.
