If you encounter difficulties or issues in the system operation, we suggest consulting the possible causes and simple solutions provided below. If this information is not sufficient to resolve the difficulty, please contact Treetech's SAC team or your authorized representative.

The equipment displays self-diagnostic messages on the display.

The firmware of the Smart Device Gateway - SD+ constantly checks the integrity of its functions and the connected sensors and modules. Any anomaly detected is signaled through its fault contact. Messages will be displayed on the SD+ screen, aiding in the fault diagnosis process.

The meaning of fault codes is shown in the tables below, respecting the digit of the display where the code appears. The system of indicating codes is in hexadecimal encoding. In case of simultaneous faults, the number indicated in a given digit will be the sum of individual errors. The table below shows the possible error combinations in each digit.
