Error messages

5.4.1

Type of error

Errors that occur during commissioning or measuring are displayed immediately. If two or more
system or process errors occur, the error with the highest priority is the only one shown on the
display.
The measuring system distinguishes between two types of error:
• System error: this group includes all device errors, for example communication errors, hardware
errors, etc. ( ä 51).
• Process error: this group includes all application errors, e.g. measuring range exceeded
( ä 54).

1 Error type: P = process error, S = system error
Error message type: $ = fault message, ! = notice message, (definition:  ä 51)

3 Error designation: e.g. S. V. RANGE CH1. = sound velocity of channel 1 is outside the measuring range
4 Error number: e.g. #492
5 Duration of most recent error occurrence (in hours, minutes and seconds)

Error message types

Users have the option of weighting system and process errors differently, by defining them as either
Fault messages or Notice messages. This is specified by means of the functions in the function
matrix.  ä 65. Serious system errors, e.g. module defects, are always identified and classed as
"fault messages" by the measuring device.
Notice message (!)
• Displayed as  Exclamation mark (!), error group (S: system error, P: process error).
• The error in question has no effect on the outputs of the measuring device.
Fault message ( $)
• Displayed as  Lightning flash ($), error designation (S: system error, P: process error)
• The error in question has a direct effect on the outputs.
The response of the outputs (failsafe mode) can be defined by means of functions in the function
matrix ( ä 56).
Note!
• Error conditions can be output via the relay outputs.
• If an error message occurs, an upper or lower signal level for the breakdown information
according to NAMUR NE 43 can be output via the current output.
