Cascading

To implement linked protective fields, up to three MLC 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 ad-
ditional expense for control and connection. The host system performs all necessary processor tasks, pro-
vides 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 connec-
tion can be created.
