  • Page 9: Use And Application

    IO-Link interface for service and process data, and for parameterization Description In addition to the usual standard functions, LGS series light grids feature a range of useful extra functions previously found only in much more expensive device classes. These functions include ultra-quick object detection even with beam crossover, the option of identifying objects, and remote communication via an IO- Link interface.

This can be achieved by swapping the emitter and receiver, or by ensuring a sufficient distance between the two light grids.

  • Page 18: Connecting The Sensor Rails

    LGS Series Installation Connecting the Sensor Rails Caution! Electrical connection Wiring work that requires the opening and closing of electrical connections must always be performed with the power disconnected. Use a Class 2 power supply to supply the power (certified according to UL 1310).
  • Page 19 LGS Series Installation Function test: When the strip is activated for less than 1.2 s, the transmitter beams switch off and the outputs on the receiver strip switch on in the same way as when a beam is interrupted. The outputs for the height control can also be tested in this way, if the relevant height control parameters are available.
  • Page 20 LGS Series Installation Height Control Outputs (H1, H2, H3) These three independent signal outputs are active if objects in the detection field match the position of the taught-in height controls see chapter 7.1.2. The outputs then report the same statuses as the function status indicators 5 (H1), 6 (H2), and 7 (H3).

  • Page 21: Storage And Transportation

    LGS Series Installation 1. Make up a grounding cable (max. 1 mm ) using the supplied cable lug. 2. Remove one housing screw from the cover at the cable end, using a Torx T8 screwdriver. 3. Place the cable lug with the prepared cable under the cover and tighten the housing screw again.

    LGS Series Commissioning Commissioning Final Assembly Checking the Mounting and Settings 1. Check the position of the light strips in relation to one another. The emitter strip and receiver strip must be aligned with one another with an accuracy of approximately ± 5°.

  • Page 23: Operation

    LGS Series Operation Operation Operating the Light Grid No objects or height controls are parameterized on delivery. The grid is operated using the touch field on the front of the receiver strip. The system can be parameterized as required using the two operating elements and the icons on the receiver strip.

  • Page 28: Object Detection (Overhang Control)

    LGS Series Operation Touch field Parameter icon Description Signal tracking Explanation of function: In non-stable ambient conditions, e.g., soiling and temperature changes, signal tracking ensures that the response threshold Object remains constant. Reflective objects that are position occasionally present along the detection field can distort signal tracking and cause switching faults.

  • Page 29: Monitoring The Object Height With Height Controls

    LGS Series Operation 7.1.2 Monitoring the object height with height controls The LGS switching light grid has been designed e.g. to monitor the load heights of pallets. An H switching output is therefore allocated for every load height. For example, the upper edge of the smallest object is taught in as height control 1 (H1), the upper edge of the middle object as height control 2 (H2) and the upper edge of the largest object as height control 3 (H3).

  • Page 30: Object Identification

    LGS Series Operation 7.1.3 Object identification The switching light grid can identify solid or perforated objects in the detection field from the interrupted light beams. Output Q is switched for the entire time that the object is in the detection field.

  • Page 31: Commissioning And Operating The Light Grid With Io-Link

    LGS Series Operation Commissioning and Operating the Light Grid with IO-Link Commissioning with IO-Link To activate the sensor via the IO-Link, proceed with the following steps: 1. Set the corresponding port on the IO-Link master to which the sensor is con- nected to IO-Link status.

  • Page 33: Maintenance And Repair

    If it appears that safe operation of the sensor system is no longer possible, it must be taken out of operation and secured against inadvertent use. Always send both parts of the device (transmitter and receiver strip) to Pepperl+Fuchs together for repair.
