Disabling the programming mode

Programming mode is disabled if you do not press an operating element within 60 seconds after you
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).

Error messages

Type of error
Errors that occur during commissioning or measuring operation are displayed immediately. 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 errors: this group includes all device errors, for example communication errors, hardware
errors, etc. → see Page 80
• Process error: this group comprises all application errors, e.g. measuring range exceeded
→ see Page 84

Fig. 43: 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. S.VELOC RANGE = sound velocity outside the measuring range
4 Error number: e.g. #491
5 Duration of most recent error occurrence (in hours, minutes and seconds)
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 func-
tion 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 86).
Note!
• Error status can be output via the status output.
• If there is an error message present a higher or lower signal on alarm level can be output via the
current output in accordance with NAMUR Recommendation NE 43.
