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 → ä 66)
• W (Warning):
Instrument continue measuring, error message is displayed.
Indicated by a flashing symbol.
(For a description of the codes see → ä 66)
• 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 → ä 66)
Error messages
Error messages appear as four lines of plain text on the display. In addition, a unique error code is
also output. A description of the error codes is given on → ä 66.
•The "diagnostics" (0A) function group can display current errors as well as the last errors that
occurred.
• If several current errors occur, use
O
or
S

• The last occurring error can be deleted in the "diagnostics" (0A) function group
with the function "clear last error" (0A2).
