5.4 Error messages
5.4.1 Type of error
Errors which occur during commissioning or measuring operation are displayed immediately. 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:
• System errors: This group comprises all device errors, e.g. communication errors, hardware
errors, etc. → ä 97
• Process errors: This group comprises all application errors, e.g. empty pipe, etc. → ä 102

1 Error type: P = process error, S = system error
2 Error message type: $ = fault message, ! = notice message

4Error number
5 Duration of most recent error occurrence (hours:minutes:seconds)
5.4.2 Error message type
Users have the option of weighting certain errors differently, in other words having them classed as
"Fault messages" or "Notice messages". You can define messages in this way with the aid of
the function matrix (see the "Description of Device Functions" manual).
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 type (S: system error, P: process error).
• The error in question has no effect on the outputs of the measuring device.
Fault message ( $)
• Displayed as → Lightening flash ( $ ), error type (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 105
!
Note!
• Error conditions can be output via the relay outputs or the fieldbus communication.
• 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.
