Discovery error code troubleshooting

During System Discovery which establishes the radio communication to the MLPE units, the discovery process may encounter an error that will be displayed on the MMU and CC (Cloud Connect) data logger LCD.

Many of the error codes reflect problems with installation.  Discovery will not finish unless all errors are corrected. Once Discovery initiates without errors, it is fine to leave the site.

To test the gateways see Gateway Test on CC and CCA using App and How To Gateway Test

Error Number Description
1 The number of Gateways that can communicate with the data logger does not match the amount specified on the Equipment page.
                                          
  • Verify that number of Gateways installed matches the amount entered on the Equipment page. If needed correct the number of Gateways installed.
  • If you configured your system using it's web page, you can view the number of gateways configured by using the Equipment page.
  • If you configured the system via the Tigo SMART App, click 'back' until you see a page asking how many modules and how many gateways.
  • If the numbers match but the error persists, check Gateway wiring and termination.

  • Check Gateway wiring and termination
  • The terminating resistor should be installed on the last Gateway in the chain
  • Older Gateways need to have the jumper set inside (last Gateway only)

11 Discovery incomplete - lost communication between Gateway and smart modules
 
  • Check proximity to modules
    • Check RSSI map via laptop or your Smart Phone to verify all units have RSSI of at least 80 (RSSI = Radio Signal Strength Indicator). If you see dark blue + grey area on your RSSI map it's a good indication that you should improve the GW position, or add an additional GW
  • Check Gateway wiring and termination
  • Ensure that all smart modules are powered on, and allow enough time for Discovery to complete before sunset

23 Configuration file missing or incomplete
 
  • Verify that optimizer serial numbers were entered correctly in the system configuration
    • Go to 'My Installations' and under 'Pending Systems' find your site and press 'Configure'. Go to 'System Mapping' and make sure you have all the barcodes entered correctly; no typos or empty spaces. Also notice that MAC IDs must be exactly 16 characters long, and contain only the digits 0-9 and uppercase letters A-F. Once done hit 'Save' and restart discovery on the CC using the Tigo SMART App or the LCD menu options: 2. control > 1. discovery.
