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 error:
This group includes all device errors, e.g. communication errors, hardware errors,
•
Process error:
This group comprises all application errors, e.g. empty pipe etc.

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.
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 and the outputs of the measuring
device.
• Displayed as
→
Exclamation mark (!), error type (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 operation and has an immediate effect on the
outputs.
• Displayed as
→
Lightening flash (
$
), error type (S: system error, P: process error)
• Displaying the device status on PROFIBUS DP/PA
!
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.
