DANGER
Hazard due to lack of effectiveness of the protective device
A safety light curtain with the beam coding “uncoded” can be affected by senders with
code
1 or code

A safety light curtain with code
1 or code
2 can be affected by senders with the beam
coding “uncoded”.
Safety light curtains with the same beam coding can interfere with each other.
b
If systems are in close proximity to each other, only use code
1 and code
2.
Using beam coding
Use suitable beam codings to prevent mutual interference from neighboring systems.
b
Configure one safety light curtain with code 1 and the other safety light curtain
with code 2.

Figure 16: Trouble-free operation due to beam coding
In the figure, the beam coding of systems in close proximity to each other is different.
The system with code
2 is not affected by the beams of the system with code
1.

Using reversed direction of transmission
Important information
NOTE
The direction of transmission of the system can be changed during installation by
switching the positions of the sender and receiver. The sender and receiver are easy to
exchange with each other if they are wired in the same way.
Using reversed direction of transmission
The 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
