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 error:
This group includes all device errors, e.g. communication errors, hardware errors etc.
•
Process error:
This group includes all application errors, e.g. fluid not homogeneous, 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. MEDIUM INHOM. = fluid is not homogeneous
4
Error number: e.g. #702
5
Duration of most recent error occurrence (in hours, minutes and seconds)
5.3.2
Error message type
Users have the option of weighting system and process errors differently, by defining them as
Fault
messages
or
Notice messages
. You can define messages in this way with the aid of the function
matrix (see the "Description of Device Functions" manual).
Serious system errors, e.g. module defects, are always identified and classified 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).
Fault message (
$
)
• The error in question interrupts or stops the current 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 (
$
), error type (S: system error, P: process error)
!
Note!
For security reasons, error messages should be output via the status output.
