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 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
•
Process error:
This group includes all application errors, e.g. fluid not homogeneous, etc.

5.4.2
Error message types
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
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 measuring operation.
• Displayed as
→
Exclamation mark (!), type of error (S: system error, P: process error)
• Displaying the device status on PROFIBUS DP/PA
Fault message (
$
)
• The error in question interrupts or stops the current measuring operation.
• Displayed as
→
Lightning flash (
$
), type of error (S: system error, P: process error)
• Displaying the device status on PROFIBUS DP/PA
!
Note!
• Error conditions can be output via 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.
