Warning messages are marked in yellow. The function of the pump is restricted when
there is a warning (see the “Warning messages” section).
Example: cable break detection on analogue input.

“Error messages” section). Example: blocking rotor.
Further status displays can be displayed, if they are available, by turning the operating button
