11.2 Deviation between process value and level
Description
Troubleshooting
The level indicated is too
low, although the level is
within the measuring range
►
Check whether the event [Signal fault] is provided, if
applicable, carry out the instructions in
►
Check whether the event [Plausibility error] is provided, if
applicable, follow the instructions in
►
Fill the tank until at least one electrode of the measuring
range is completely covered�
►
Read the parameter [Index of level edge]
Further procedure:
→ 11.2.1 Evaluate the index of the
The process value is in the
measuring range although
the tank is empty�
►
Check whether the event [Signal fault] is provided, if
applicable, carry out the instructions in
►
Check whether the event [Plausibility error] is provided, if
applicable, carry out the instructions in
�
►
Carry out an empty and full adjustment
If only an empty adjustment is possible:
►
Fill the tank until at least one electrode of the measuring
range is completely covered�
►
Read the parameter [Signal strength]
�
►
Calculate the minimum recognition threshold (signal
strength x 14).
►
Write the determined value to parameter [Minimum
recognition threshold]
The process value is in the
measuring range although
the tank is full�
►
Check whether the event [Signal fault] is provided, if
applicable, carry out the instructions in
►
Check whether the event [Plausibility error] is provided, if
applicable, carry out the instructions in
�
►
Carry out an empty and full adjustment
If only a full adjustment is possible:
►
Empty the tank until at least one electrode of the
measuring range is completely uncovered�
►
Read the parameter [Signal strength]
�
►
Calculate the minimum recognition threshold (signal
strength x 14).
►
Write the determined value to parameter [Minimum
recognition threshold]
