    Attention Laser! This symbol warns of possible danger caused by hazardous laser radiation. The light section sensors of the LRS series use a class 2M laser: Viewing the laser output with certain optical instruments, e.g. magnifying glasses, microscopes or binoculars, may result in eye damage.

  • Page 12: Safety Notices

    The protection of personnel and the device cannot be guaranteed if the device is operated in a manner not complying with its intended use. The light section sensors of the LRS series are laser sensors for presence detection of objects in defined areas.

  • Page 13: Working Safely

    Adjustments: Do not attempt any adjustments to or alterations of this product. Do not open the protective housing of the light section sensor. There are no user-serviceable parts inside. The glass optics cover is the only aperture through which laser light may be observed on this product. Leuze electronic Technical description LRS...

  • Page 21: Line Range Sensor - Lrs

    Device description 4.1.3 Line Range Sensor - LRS Line Range Sensors are designed to perform proximity object detection along the laser line. Similar to a light barrier or a laser scanner, the sensor detects the presence of objects through scanning. With individual configuration, one sensor can be used to detect single or multiple objects.

  • Page 22: Operating The Sensor

    LRSsoft. Detection operation In detection operation, the LRS 36/6 is connected to the process control via its 4 switching outputs; the LRS 36/PB is connected to the process control via PROFIBUS. Alternatively, the LRS can be operated via the Ethernet interface on X2, see chapter 10 "Integrating the LRS in the process control (Ethernet)".

  • Page 23: Triggering - Free Running

    - The shortest possible time interval between two successive trigger edges is 10ms. Notice! Ex works, the LRS is set to Free Running (shown on display: fRun). In order for it to respond to signals on the trigger input, the operating mode must be set via the LRSsoft con- figuration software to Input Triggered (shown on display: Trig).

  • Page 24: Profibus Trigger

    So that a measurement can be triggered on each PROFIBUS cycle, the PROFIBUS trigger of the LRS responds to a change of master output byte uTrigger. The control only needs to increment the trigger value in order to initiate a new measurement.

  • Page 25: Detection Functions Lrs

    4.3.1 Inspection Task The LRS lets you operate with up to 16 individual inspection tasks, each of which may contain up to 16 rectangular analysis windows (AWs) that can be configured independently and that may overlap arbitrarily. 1-16 AWs can be defined for each inspection task. The results of the individual AWs may be combined via logic operations (AND, OR, NOT).

  • Page 26: Analysis Results

    Detailed evaluation results such as, e.g., the status of all AWs, the number of hit points and the state of the switching outputs are transmitted via Ethernet and can be queried via PROFIBUS. For more information please refer to chapter 10. Technical description LRS Leuze electronic...

    In order to be able to establish an UDP communication with the PC, the IP address of your PC and the IP address of the LRS must lie in the same address range. The LRS has no built- in DHCP client, so that you need to set the address manually. This is done the easiest way via the PC.

  • Page 55: Setting An Alternative Ip Address On The Pc

    Set the subnet mask of the PC to the same value as on the LRS. Close the configuration dialog by confirming all windows using OK. Connect the interface X2 of the LRS directly to the LAN port of your PC. Use a KB ET-…-SA-RJ45 cable for the connection, see table 15.7 The PC first tries to establish a network connection via the automatic configuration.

    Integration of the LRS 36/PB in the PROFIBUS Sensor state Sensor status byte uSensorState contains the following information: Designation Meaning ErrM Error mode, permanent sensor malfunction. Command mode: the sensor is in command mode. The queries from the control are not processed and the measurement data are frozen (indicated by the constant scan number).

    General maintenance information Usually, the light section sensor does not require any maintenance by the operator. Cleaning In the event of dust buildup, clean the LRS with a soft cloth; use a cleaning agent (commercially available glass cleaner) if necessary. Notice! Do not use aggressive cleaning agents such as thinner or acetone for cleaning the light sec- tion sensors.
