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 errors:
Includes all device errors, e.g. communication errors, hardware errors, etc. → ä 78
• Process errors:
Includes all application errors, e.g. fluid not homogeneous, etc. → ä 83

Fig. 26: Error messages on the display (example)
1 Error type: P = process error, S = system error
Error message type: $ = Fault message, ! = Notice message

3 Error designation: e.g. FLUID INHOM. = fluid is not homogeneous
4 Error number: e.g. #702
5 Duration of most recent error occurrence (in hours, minutes and seconds)
5.4.2

Error message type

The measuring device permanently assigns two types of error messages (fault message or notice
message) to system errors and process errors, thereby giving them a different weighting.
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 and the outputs of the
measuring device.
• Displayed as → Exclamation mark (!), type of error (S: system error, P: process error)
Fault message ( $)
• The error in question stops or interrupts running operation and has an immediate effect on the
outputs. The response of the outputs (failsafe mode) can be defined by means of functions in the
function matrix.
• Displayed as → Lightning flash ( $ ), type of error (S: system error, P: process error)
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.
