In case you encounter difficulties or problems operating the system, we suggest consulting the possible causes and simple solutions presented below. If this information is not sufficient to resolve the difficulty, please contact Treetech's CS team or its authorized representative.
The equipment shows self-diagnosis messages on the display
The Temperature Monitor - TM firmware constantly checks the integrity of its functions and the sensors and modules connected to it. Any anomaly detected is signaled via its fault contact. Messages will be indicated on the TM display, assisting in the fault diagnosis process.
The meaning of the fault codes is shown in the following tables, respecting the digit on the display where the code appears. The code indication system is in hexadecimal coding. If simultaneous failures occur, the number indicated in a given digit will be the sum of the individual errors. Below is a table with possible combinations of errors in each digit.
Code of combinations of possible active errors
Code | Description |
0 | No active diagnosis |
1 | Diagnosis 1 active |
2 | Diagnosis 2 active |
3 | Diagnosis 1 + 2 active |
4 | Diagnosis 4 active |
