MN300840 REV A8
Sensor is not receiving power (10 to 30 VDC). Check wiring to the
sensor as well as the power supply.
Sensor cannot acquire a valid level reading. Make sure the sensor is
installed properly within the application and the probe is touching liquid.
Sensor is likely acquiring a false echo from some interference close to
the probe. Running an Empty Signal Scan should address this issue.
You may have received a probe that was cut from its original factory
setting. When Factory Reset is clicked in WebCal, the default restores
this original length. The correct physical length of the probe must be re-
entered and written to unit before the sensor is installed in your
application.
