5.3.3 Disabling the programming mode
Programming mode is disabled if you do not press an operating element 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).
5.4 Error messages
5.4.1 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:
Includes all device errors, for example communication errors, hardware errors, etc.
→
ä
63
• Process errors:
Includes all application errors, for example inhomogenous fluid, 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
4 Error number
5 Duration of most recent error occurrence (hours:minutes:seconds)
5.4.2 Error message types
The measuring device always assigns system and process errors which occur to two types of error
messages (
fault or notice messages ), resulting in different weightings
→
ä
62.
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 the current measuring operation.
• Displayed as
→
Exclamation mark (!), type of error (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 the current measuring operation.
• Displayed as
→
Lightning flash (
$
), type of error (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
output value OUT (AI Block).
