    LGM Series Product Description Figure 2.5 Receiver unit connection layout + UB SC (Stability Control, Out) 0 V DC C/Q (IO-Link / Out) Q (Out) not connected not connected Teach-In (In) IO-Link communication is established via the C/Q (Pin 4) connection.

  • Page 10: Installation

    LGM Series Installation Installation Mounting Make sure the detection field is free from obstacles. The first and last beams within the detection field are used for optical synchronization of emitter and receiver units. If both beams are blocked, synchronization is lost and the mea- surement is inhibited.
  • Page 11 LGM Series Installation Preparation Mark the position of the holes. Focus on the lateral continuous line on the light grid Mark the position of the holes. Using a 4.5 diameter drill, drill right through the housing. Deburr the hole. Repeat the first steps to drill all the holes.

    LGM Series Operation Use preset parameters to configure, parameterize, and diagnose the sensors. To parameterize the sensors with an engineering tool, use the device description (IODD), which can be loaded into all system environments with IO-Link support. To operate the sensor in an FDT environment, you can also use a DTM.
