Safety light curtain principle
The protective field is between the two twin sticks and is defined by the protective field
height and the protective field width.
The two twin sticks automatically synchronize themselves optically. Each twin stick pro‐
vides an OSSD and a so-called multifunctional connection. The OSSDs are integrated
into the machine controller. Either a reset button or an EDM can be connected to the
multifunctional connections.
