3.3 Cascading

To implement linked protective fields, up to three SLC safety light curtains can be cascaded
one after the other.
Adjacent protective fields, e.g., for stepping behind protection, can thereby be implemented
without any additional expense for control and connection. The host system performs all nec-
essary processor tasks, provides indicators and the receiver-side interfaces to the machine and
command devices.
Devices with different resolutions can be combined.
With mounting brackets (see chapter 15 "Order guide and accessories"), an L or U-shaped
fixed connection can be created.
