11.2.1 Evaluate the index of the level edge
Index of level edge Troubleshooting
• The substitute value
"255" is provided�
Reason: the measured
signal is too weak�
► Increase the sensitivity of the sensor (→ 10.2.1) �
► Check the [Minimum recognition threshold] and reduce it
or reset it to factory setting (→ 10.2.1) �
► Reduce the wall thickness of the tank�
• The index of the level
edge maintains the
minimum value even
though the tank continues
to be filled�
► Check the grounding and, if necessary, correct it (→ 6.6)
When used on a bypass pipe:
► Insert the supply cable into the adapter�
• The index of the level
edge is in the measuring
range� However, the
position significantly
deviates from the actual
level�
► Read the parameter [Signal strength] (→ 10.2.3) �
Further procedure: → 11.2.2 Evaluate signal strength
and filling edge sharpness�
11.2.2 Evaluate signal strength and filling edge sharpness
Parameter / value Troubleshooting
Signal strength < 10 ► Reduce the wall thickness of the tank�
► Increase the sensitivity of the sensor (→ 10.2.1) �
► Read parameter [Filling edge sharpness] (→ 10.4) �
Filling edge sharpness
< 50
► Install the unit where the edge of the level is at a right
angle to the active face�
