SG4 BASE7/741 GENERAL INFORMATION1.1 GENERAL DESCRIPTIONThe safety light curtains are optoelectronic multibeam devices that are used to protect working areas that, inpresence of machines, robots, and automatic systems in general, can become dangerous for operators that canget in touch, even accidentally, with moving parts.The light curtains are intrinsic safety systems used as accident-prevention protection devices and aremanufactured in accordance with the international Standards in force for safety, in particular:NORM DESCRIPTIONEN 61496-1: 2013 Safety of machinery: electrosensitive protective equipment.Part 1: General prescriptions and tests.EN 61496-2: 2013 Safety of machinery: electrosensitive protective equipment - Particular requirementsfor equipment using active optoelectronic protective devices.EN ISO 13849-1: 2015 Safety of machinery. Safety-related parts of control systems.Part 1: General principles for designEN 61508-1: 2010Functional safety of electrical/electronic/programmable electronic safety-relatedsystems.Part 1: General requirementsEN 61508-2: 2010Functional safety of electrical/electronic/programmable electronic safety-relatedsystems.Part 2: Requirements for electrical/electronic/programmable electronic safety-related systemsEN 61508-3: 2010Functional safety of electrical/electronic/programmable electronic safety-relatedsystems.Part 3: Software requirementsEN 61508-4: 2010Functional safety of electrical/electronic/programmable electronic safety-relatedsystems.Part 4: Definitions and abbreviationsEN 62061:2005/A2: 2015 Safety of machinery. Functional safety of electrical/ electronic/programmableelectronic safety-related control systems.The device, consisting of one emitter and one receiver contained inside aluminium profiles, generates infraredbeams that detect any opaque object positioned within the light curtain detection field.The emitter and the receiver are equipped with the command and control functions.The connections are made through one or more connectors as specified in cfr.ELECTRICAL CONNECTIONSpage 27.The synchronisation between the emitter and the receiver takes place optically, i.e. no electrical connectionbetween the two units is required.The microprocessor guarantees the check and the management of the beams that are sent and received throughthe units: the microprocessor – through some LEDs – informs the operator about the general conditions of thesafety light curtain (cfr.USER INTERFACE AND DIAGNOSTICS page 42).The receiver is the main controller for all functions. It monitors all safety actions in case of failure and performsgeneral functions as well.During installation, an user interface facilitates the alignment of both units (cfr.ALIGNMENT PROCEDURE page33).As soon as an object, or a limb or the operator’s body accidentally interrupts one or some of the infrared beamssent by the emitter, the receiver immediately opens the OSSD outputs or trigger Safety State over connectedsafety Fieldbus.
