    • Software Setup Initial setup of the LOE and individual Modbus sensors is done via an embedded web server. The embedded server can be accessed by using either the serial number or local IP address of the LOE and a web browser (Internet Explorer, Chrome, Firefox, etc).
  • Page 13 On the Sensor Information screen you will see the IP Address of the newly installed LOE. (See Figure 2.6.) Type the LOE’s IP address into your browser’s address bar (See Figure 2.7). Figure 2.6 Figure 2.7 Logging on to the LOE Embedded Web Server The LOE’s embedded webpage should now be open, showing the Main Display page (See Figure 2.8).
  • Page 14 Click on Home to bring up the Menu page (See Figure 2.9). The first menu link clicked during each session will prompt a User Name and Password login for the LOE (See Figure 2.10). The default User Name is admin, and the default Password is password.

  • Page 15: Removal Instructions

    Change Numb of Sensors On Line to reflect the total number of Modbus sensors you will be connecting to your LOE. Click Change (or press Enter) to send the new value to the LOE. With Sensor Number to View set to 1 (for the latest sensor added to the Modbus network), set New Sensor Number to the highest available number.

  • Page 42: Chapter 5: Maintenance

    Chapter 5: Maintenance • General Care Your LOE series controller is very low maintenance and will need little care as long as it is installed correctly. However, in general, you should: • Avoid applications for which the sensor was not designed, such as extreme temperatures, contact with incompatible corrosive chemicals and fumes, or other damaging environments.

  • Page 43: Calibration

    • Calibration This procedure uses targets at known distances to calibrate the LOE sensor’s accuracy. A wall or other large, flat object is recommended for the long range target. • Point the sensor at a target at a known distance near the maximum range of the sensor (See Figure 5.1).
