Displaying error messages
5.3.1
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
:
This group comprises all device errors, e.g. communication errors, hardware faults, etc.
•
Process errors
69:
This group comprises all application errors, e.g. empty pipe, etc.

Error messages on the display (example)
1
Error type:
– P = process error
– S = system error
2
Error message type:
–
$
= fault message
– ! = notice message
3
Error designation: e.g. EMPTY PIPE = measuring tube is only partly filled or completely empty
4
Error number: e.g. #401
5
Duration of most recent error occurrence (in hours, minutes and seconds)
5.3.2
Error message types
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 (
"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
Lightning flash (
$
), error type (S: system error, P: process error).
• The error in question has a direct effect on the outputs.
The response of the individual outputs (failsafe mode) can be defined by means of the "FAILSAFE
MODE" function in the function matrix (
"Description of Device Functions" manual).
!
Note!
For safety reasons, error messages should be output via the status output.
