5.5.3 Display of error messages
Type of error
Errors that occur during commissioning or measuring are displayed immediately on the local dis-
play. 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
errors, etc.
→
Page 72
• Process error: This group includes all application errors, e.g. fluid not homogeneous, etc.

Fig. 27: 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. FLUID INHOM. = fluid is not homogeneous
4 Error number: e.g. # 702
5 Duration of most recent error occurrence (in hours, minutes and seconds)
Error message type
The flowmeter assigns system error and process error to two error message types (fault message or
notice message) in accordance with a predefined algorithm and classifies them accordingly
→
Page 72 ff.
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 measurement currently in progress.
• Displayed as
→
Exclamation mark (!), error type (S: system error, P: process error).
• Presentation on the FOUNDATION Fieldbus
→
Notice messages are transmitted to subsequent
function blocks or higher-level process control systems by means of the status “UNCERTAIN” of
the output value OUT (AI Block).
Fault message (
$
)
• The error in question interrupts or stops measurement currently in progress.
• Displayed as
→
Lightning flash (
$
), error designation (S: system error, P: process error).
• Presentation on the FOUNDATION Fieldbus
→
Fault messages are transmitted to subsequent
function blocks or higher-level process control systems by means of the status “BAD” of the out-
put value OUT (AI Block).
