Important information
DANGER
Hazard due to lack of effectiveness of the protective device
If 2 or more identical safety light curtains (same resolution and same protective field
height) are used in a cascade, the protective device can be disabled if the connecting
cables are switched round.
b
Make sure (e.g., by routing the cables appropriately) that the operator is unable to
switch round the connecting cables of 2 senders or receivers of the same type.

Integrating safety light curtains in a cascade
Y
ou can use cascading to connect up to 3 safety light curtains, e. g., to provide reliable
presence detection. The connected devices act like a long safety light curtain. Only one
device, the host, is connected to the control cabinet. The second device, guest 1, is
connected to the host. The third device, guest 2, is connected to guest 1.
Advantages of cascading:
Rapid connection, no additional external circuitry required
No optical mutual interference between the protective fields within a cascade.
Host and guests are operated with the same beam coding.
Resolution and protective field heights of the individual systems may be different
