2 Product OverviewThe SX5 Safety Laser Scanner is an electro-sensitive protective equipment (ESPE). It employs active opto-electronicsproductive devices responsive to the diffuse reflection of a radiation (AOPDDRs), according to the definition andrequirements of international safety standard IEC 61496-3. The optical radiation is a class 1 infrared laser generated withinthe device.When the device is properly installed on a machine that presents a risk of personal injury, it provides protection by makingthe machine revert to a safe condition before a person reaches the hazardous points.The working principle is that the invisible beam of the laser creates a two-dimensional safety area that must be crossed toreach the dangerous points. In this way the dangerous movement of the machine can be stopped before anyone reachesthe hazard point.The safety area can be horizontal or vertical and by using a Graphic User Interface, its shape can be planned according tothe application needs.The beam is emitted in short interval pulses and they are reflected by objects in the safety area. The device calculates thedistance to the object by measuring the time interval between the transmission of the pulse and its reception after beingreflected (time-of-flight principles).The safety area is scanned by a mirror that deflects the light pulses over the 275° area around the device by rotating at aconstant speed. In this way, all the opaque objects that have a certain dimension can be detected in the safety area.Within the sensing range of the scanner, two areas can be monitored simultaneously: one is the Safety Zone, that is used todetect operators or objects entering a hazardous area; the other is the Warning Zone that can be defined with a longerdistance than the Safety Zone, allowing a configuration to detect objects that are approaching the Safety Zone.Configurations can also be created with one Safety Zone and two different Warning Zones.The scanner will only turn its Safety Outputs ON when the Safety Zone is free of obstructions, either automatically orfollowing a manual restart (reset) signal, depending on the operating mode.The scanner should be connected to a self-checking safety module, safety controller, or safety PLC/PES that has the abilityto perform the external device monitoring (EDM) function. This function ensures the fault detection capability required byU.S. Control Reliability and ISO 13849-1 Category 3 or PL d for controlling final switching devices (FSDs) or MachinePrimary Control Elements (MPCEs). The device that the scanner is connected to must perform to the level of performancerequired by the risk assessment.Warning Zone (WZ)Safety Zone (SZ)Figure 1.
