Warning Status and Warning Status Application
The current warning is displayed by a message in the warning status and can be
used for an early message of a critical operational condition. If a warning is present,
this is indicated by the flashing red LED and the display field WARN of the control
unit. If several warnings are present, the warning status is displayed as the sum of
the individual warning codes.
The warning masks created through parameters
