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.
Prerequisites
•
The type codes of the connected sender devices are identical at the following
place in the number sequence.
°
Variant 1: C4P-******0***
°
Variant 2: C4P-******1***
•
The type codes of the connected receiver devices are identical at the following
place in the number sequence.
°
Variant 1: C4P-******0***
°
Variant 2: C4P-******1***
•
The type codes of the sender devices may differ from the receiver devices at
this place in the number sequence if the sender and receiver devices are not
connected with each other.
Integrating safety light curtains in a cascade
You 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
