CHAPTER 6
FUNCTIONS
This chapter describes all the functions of the light curtain.
The main function of the light curtain is the safe detection: when any object with
dimensions equal or greater than the light curtain resolution is placed anywhere within
the detection zone, the light curtain will detect it and its safe outputs (OSSDs) shall go to
the OFF- state.
SH4 performs this detection function according to IEC EN 61496-2.
