7.2.1.2.2 Menu: Diagnosis
In the Diagnosis section, the user is provided with information about faults and
warning messages that pertain to the pump set or process. The frequency inverter
can be in fault (standstill) or warning (operational) status. The user can also find
previous messages in the history.
Messages
All monitoring and protective functions trigger warnings or alerts. These are
signalled via the amber or red LED of the LED traffic light function.
A corresponding message is output on the control panel display. If more than one
message is output, the last one is displayed. Alerts have priority over warnings.
