WARNING

LOSS OF INPUT FUNCTION

Do not operate the BMX DDM 16022H at 70 °C (158 °F) if the sensor power supply is greater than 29.0 V or less than 21.1 V. Overheating the module can cause the loss of the input function.

Failure to follow these instructions can result in death, serious injury, or equipment damage.
