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 which occur during commissioning or measuring operation are displayed imme-
diately. 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. → see Page 88
• Process errors: This group comprises all application errors, e.g. empty pipe,
etc. → see Page 92
Fig. 44: 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.
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 functions in
the function matrix (see Page 94).
!
Note!
For security reasons, error messages should be output via the status output.
