NOTEEven if abnormality or disconnection of the terminal block temperature sensor occurs, AL22 may not be output and AL04 may be generated.

CAUTIONThere is a time lag between sensor failure and sensor abnormality detection.Since the failed measurement value is output, the current output also becomes undefined.When an error is detected, it becomes the output set with this parameter.However, when sensor burnout is set to OFF, it may be held with indefinite measurement value, so please understanding this point.

CAUTIONThere is a time lag between sensor failure and sensor abnormality detection.Since the failed measurement value is output, the current output also becomes undefined.For this reason, until failure of Sensor 1 switches to Sensor 2, or　”Output state at sensor burnout” due to failure of Sensor 2 The output becomes undefined until switching to the output.When an abnormality is detected, it is output according to the measured value of Sensor 2 or "Output state at sensor burnout".
