5.4Display and acknowledging error messages
Type of error
Errors that occur during commissioning or measuring are displayed immediately on the local display. If two or more system or process errors occur, the error with the highest priority is the one shown on the display.
The measuring system distinguishes between two types of error:
•A (Alarm):
Instrument goes into a defined state (e.g. MAX 22 mA)
Indicated by a constant 
symbol.
(For a description of the codes, see Table 9.2 on Page 79)
•W (Warning):
Instrument continue measuring, error message is displayed.
Indicated by a flashing 
symbol.
(For a description of the codes, see Table 9.2 on Page 79)
•E (Alarm / Warning):
Configurable (e.g. loss of echo, level within the safety distance)
Indicated by a constant/flashing 
symbol.
(For a description of the codes, see Table 9.2 on Page 79)
