4.3.4.1
Using beam coding
Important information
DANGER
Hazard due to lack of effectiveness of the protective device
A system with the beam coding “uncoded” can be affected by an active unit with code 1
or code 2.
A system with code 1 or code 2 can be affected by an active unit with the beam coding
“uncoded”.
Systems 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 system

Figure 13: Trouble-free operation due to beam coding
In the figure, the beam coding of systems in close proximity to each other is different.
This means that the systems do not influence each other.
Complementary information
The protective device is not influenced by coded systems of the following product
groups:
•
deTec4
•
M4000
•
C4000
In the case of systems in close proximity that are of a different product group, different
measures must be taken to prevent mutual interference.

4.3.4.2
Using reversed direction of transmission
An opposite transmission direction prevents mutual interference between adjacent sys‐
tems.
b
Align the active units of both systems back to back.
