Self-diagnostic

At a supply voltage (Vcc) ≥ 12 V it takes about 5 minutes until the sensor works in a stable
mode. Therefore, after switching on the unit, the LED will show a not stable state for up to
5 minutes.
With this function the current status of the sensor will be indicated by different flash modes of the LED.
If activated, the LED will show one out of five possible states of
the sensor:
Status
Normal
Sensor overheated
Out of measuring range
Not stable
Alarm fault
