The RS-NAGU.. is used for muting of safety light barriers and safety light curtains, so that materialtransport to or from a machine can be done. Applications can be found in the automotive industry, packaging machines or at highly automated production systems. The differentiation between human and material is done with up to four muting sensors or two safety light barriers. Inductive sensors or mechanical switches can also be used as muting sensors. Functions of the muting controllers: .. Connection of an external muting lamp .. Connection of present-sensing safeguarding devices .. Monitoring of external devices and expansion modules .. Connection of different muting-sensors (NPN,PNP and relay output) .. RS-NAGU.1 / RS-NAGU.1b / RS-NAGU.12: 3 electronic safety-semiconductor outputs. .. RS-NAGU.2f: 3 normal open safety outputs. Muting cycle If the muting sensors 1 and 2 or 3 and 4 are activated within 3 sec, RS-NAGU.. starts a muting cycle. The controlled muting light is turned on and an interruption of the light barrier will not cause a stop of the machine. If three of the four muting sensors are deactivated, the muting cycle will end after 0,25 sec. i Muting t < 3s ML a i a i 1 1 i MS4 a MS3 a MS2 i a MS1 i a i : inactive a : active : signal must overlap, e.s. both muting sensors need to be active in parallel. t < 3s 1
