™ SAFEasy TYPE 2 LIGHT CURTAINS Integrated light curtains for PRESENCE CONTROL PROTECTION • 50 and 90 mm resolution and operating distance up to 15 m • 31 x 32 mm compact profile • Versions with automatic or manual RESTART • SF2-PRESENCE CONTROL SERIES TM The SAFEasy light curtains of the SF2 series, according to the IEC 61496-1 and IEC 61496-2 standards, are very suitable for presence detection of operators exposed to risks. Different models are available with nine standard heights ranging from 300 to 1500 mm, with 50 or 90 mm resolution and an operating distance reaching 15 m. The emitter and receiver units are optically synchronised and contain all the control circuits, test input and two safety outputs inside the housing. The connection with the machine stopping circuits are guaranteed by unshielded M12 4-pole connectors for the emitter and M12 5-pole connectors for the receiver. TM The SAFEasy light curtains of the SF2 series have also integrated the test function, automatically activated every 0.5 seconds, without stopping the machine's working cycle. A wide range of industrial applications, requiring operator safety, can be solved by TM the SAFEasy light curtains, thanks to the extremely compact dimensions (31x32 mm), easy installation and excellent performances. SAFETY DEVICES SF2 PRESENCE CONTROL PROTECTION Presence control is obtained DIMENSIONS positioning horizontally the safety light curtain. This installation allows to continuously control the presence of an obstacle inside a specific area. This is a particularly useful solution when dangerous area, not visible from the machine control points, has to be protected. 2 L 53.3 14.9 1 L mm 31 CONTROLLED HEIGHT L L 1 2 (mm) 300 374 294 450 521 441 600 668 588 750 815 735 900 962 882 1050 1109 1029 1200 1256 1176 1350 1403 1323 1500 1550 1470 CONNECTIONS RECEIVER (RX) EMITTER (TX) OSSD1 PNP +24 Vdc NOT USED +24 Vdc +24 Vdc OSSD2 PNP NOT USED 0 V 0 V 1 = brown = +24 Vdc 1 = brown = +24 Vdc 2 = white = OSSD1 2 = white = NOT USED 3 = blue = 0 V 3 = blue = 0 V 4 = black = OSSD2 4 = black = NOT USED 5 =grey = TEST * * = automatic RESTART (X version) TEST/RESET function = manual RESTART (Y version) TEST/RESTART/RESET function 32 M12 x 1 TECHNICAL DATA TABLES Power supply (Vdd): 24 Vdc ± 20% (SELV / PELV) Consumption: 50 mA max. / 1 W (emitter) Model SF2-50 SF2-90 90 mA max. / 2.5 W (receiver without load) SF2 height 300 95 Light emission: infrared LED 880 nm SF2 height 450 13 7 Optic diameter: Ø 18 mm SF2 height 600 17 9 Number of controlled beams: refer to table 1 SF2 height 750 21 11 Optic interaxis: 37,5 mm (SF2-50); 74 mm (SF2-90) SF2 height 900 25 13 Resolution: 50 / 90 mm SF2 height 1050 29 15 Controlled height: refer to table 2 SF2 height 1200 33 17 Operating distance: 0.2 ... 15 m SF2 height 1350 37 19 Receiver inputs: external switches for Test and Restart Receiver indicators: 2 yellow ALIGNMENT LEDs SF2 height 1500 41 21 red BREAK LED green SAFE LED Table 1: NUMBER OF CONTROLLED BEAMS Emitter indicators: yellow WORKING UNIT CHECK LED green POWER ON LED Output type: 2 PNP Model SF2 short-circuit protection: max.1.4 A at 55°C min. 1.2 A at 0 °C SF2 height 300 334 Output current (for all loads): 500 mA max. per output SF2 height 450 481 Output voltage ON min.: Vdd - 1 V SF2 height 600 628 Output voltage OFF max.: 0.2 V SF2 height 750 775 Leakage current: 0.65 mA SF2 height 900 922 Capacitive load (pure): 100 nF max.
