If the device is used correctly, no maintenance is required in normal
operation.
8 .2 Error messages
HART communication errors are signalled with numerical codes 1 - 7.
An error message is sent if a transaction was not successful after
multiple attempts.
An error message is only displayed if an error occurs due to a
transmitted command, this means only if the error is caused by an
adjustment of the user. Errors in the communication between control
system and sensor are detected but not displayed.
The measured value line shows "Error“, the status line "HART n“
whereby "n" represents the numerical error code. The error message
is displayed up to the next key pressing.
The following table shows the error codes and gives information on the
failure reason and removal.
