Red

This error is set if the temperature

of the sensor is superior to +85 °C

or inferior to -40 °C.

This information is sent until

temperature is over range.

Set the environmental

temperature between

-40 °C to +85 °C .

Red

This error is set when the

mechanical tolerances of the

airgap parameter are out of range.

This information is sent until power

supply turns off.

The mechanical

mounting must be

adjusted.
