Message Description Action
Reference pulse calculated The position of the reference pulse is
calculated from the internal reference
pulse.
No action needed.
Reference pulse invalid An error in the reference pulse in the last
sampled tank signal.
Check Warning messages. If MicroWave
Module (MWM) Warning is active, this
might indicate a transmitter error.
Contact Emerson Service Department.
DeltaF not at setpoint The DeltaF is not correctly regulated. Check Warning Messages. If MicroWave
Module (MWM) Warning is active, this
might indicate a transmitter error.
Contact Emerson Service Department.
Tank signal clip warning The last Tank Signal was clipped. Check Warning Messages. If MWM
Warning is active, this might indicate a
transmitter error. Contact Emerson
Service Department.
No surface echo found The Surface Echo Pulse cannot be
detected.
Possible cause:
• Wrong surface threshold
• Liquid level in Blind Zone or below
probe end
Check if the configuration can be
changed so that the surface echo can be
tracked in this current region.
View the Echo Curve plot and check
surface threshold.
Predicted level The presented level is predicted. The
surface echo could not be detected.
Check if the configuration can be
changed so that the surface echo can be
tracked in this current region.
View the Echo Curve plot and check
surface threshold.
No reference echo The Reference Echo Pulse cannot be
detected.
Possible cause:
• The tank is full.
• The transmitter is configured with
wrong probe type.
• Reference Amplitude Threshold is
incorrect.
• Check the product level.
• Check that correct probe type is
configured.
• Check Reference Amplitude
Threshold.
Reduced reference echo The reference echo has been found with
reduced amplitude.
No action needed.
In full tank state The level measurement is in the full tank
state, waiting for a surface echo
detection at the top of the tank.
No action needed.
Sampling failed The sampling of the last tank signal failed. Check Warning Messages.
Invalid volume value The given volume value is invalid. The
given measurements are simulated.
Check Volume Status for details.
