A flatline means that the fill level remains at exactly the same percentage for a long time – there is no increase or decrease visible. This can have several causes:

Possible causes:

• The container is no longer in use, for example due to a jam.

• The fill level sensor is incorrectly set or defective.

Solutions:

For a card reader:

• Check if there are still successful card registrations coming in.

• Are there registrations but the fill level remains the same? Then it is likely that the sensor is incorrectly set or broken.

For a TFSU solo:

• Check on site if the container is indeed jammed.

• Compare the actual fill level with the percentage displayed in the graph.
