5.2.3 Disabling the programming mode
Programming is disabled if you do not press a key within 60 seconds following automatic return
to the HOME position.
You can also disable programming in the “ACCESS CODE” function by entering any number
(other than the customer's code).
5.3 Error messages
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.
Tthe measuring system distinguishes between two types of error:
•
System errors: This group comprises all device errors, e.g. communication errors, hardware faults,
etc.
→
see Page 85
• Process errors: This group comprises all application errors, e.g. empty pipe, etc.
→

Fig. 40: 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 / seconds
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 (see the “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.
• Not available in custody transfer mode (notice messages are always classified and treated
as fault messages in custody transer mode).
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 outputs (failsafe mode) can be defined by means of corresponding functions
in the function matrix (see Page 92).
