    During the connection, the blue light of the OELD will indicate different states. Once the connection has been successfully established and if the sensor status is normal, the OELD blue light will be lit solid blue to indicate this. Connect the mobile device to the OELD as follows: 1.
  • Page 20: Operation

    The start-up and self-test sequence of the OELD takes approximately 60 seconds. During this time the user can check that each of the functions listed below are operating correctly as well as the OELD checking the correct operation of its critical circuits and processes.
  • Page 21: Normal Operation

    Note The visual output of the OELD is derived from the 4-20 mA output of the sensor and/or status of the OELD unit. Use a suitable mobile device and the OELD app to connect to the OELD using Bluetooth® to access further diagnostic information. When used in conjunction with a Searchpoint Optima Plus or Searchline Excel, diagnostic and maintenance functions of the sensor can be accessed also.
  • Page 22: Display Screen

    During normal operation the instrument LCD shows a steady GREEN backlight. In case of a gas alarm or fault the red or yellow backlight respectively will flash. The screen is visible through the window of the OELD top cover and the display shows the gas concentration information both graphically and numerically, as well as other information including full scale range, measurement units, alarm / fault status etc.
