The measuring system distinguishes between two types of error:
• System error: This group includes all device errors, e.g. hardware errors, etc.
→ Page 71
• Process error: This group includes all application errors, e.g. fluid not homogeneous, etc.

Fig. 28: Error messages on the display (example)
1 Error type: P = process error, S = system error
2 Error message type: $ = fault message, ! = notice message, definition
3 Error designation: e.g. MEDIUM INHOM. = fluid is not homogeneous
4 Error number: e.g. #702
5 Duration of last error to occur (in hours, minutes and seconds)
5.4.2 Error message type
The measuring device always assigns system and process errors which occur to two types of error
messages (fault or notice messages), resulting in different weightings
→ Page 69.
Serious system errors, e.g. module defects, are always identified and classed as "fault messages" by
the measuring device.
Notice message (!)
• The error in question has no effect on the current operation
• Displayed as
→ Exclamation mark (!), type of error (S: system error, P: process error)
• PROFIBUS device status display, error display
→ Page 71
Fault message ( $)
• The error in question interrupts or stops the current operation
• Displayed as
→ Lightning flash ( $ ), type of error (S: system error, P: process error)
• PROFIBUS device status display, error display
→ Page 71
