Disabling the programming mode
Programming mode 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 private code).

Error message display

Type of error
Errors that occur during commissioning or measuring are displayed immediately via the
local display. If two or more system or process errors occur, the error with the highest
priority is always 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.
• Process error: this group includes all application errors, e.g. fluid not homogeneous,
etc.

1 Type of error: P = Process error, S = System error
Type of error message: $ = Fault message, ! = Notice message
2
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)
Type of error message
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
→ Page 90 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 group (S: system error, P: process error).
• FOUNDATION Fieldbus → Notice messages are relayed to downstream function
blocks or higher-level process control systems by means of the status "UNCERTAIN"
for 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)
• FOUNDATION Fieldbus → Fault messages are relayed to downstream function blocks
or higher-level process control systems by means of the status "BAD" for the output
value OUT (AI Block).
