Error messages

HART

communications errors are reported with the numerical codes 1 - 9. An error

message occurs when a transaction is not successful, despite being retried several times.

An error message is only displayed when an error occurs as a consequence of a command

sent from the display, i.e. only when an operation by the user leads to the error. Errors in the

communication between the control system and sensor are detected but not displayed.

The measuring value line shows "ERROR", the status line shows "HART

n" whereby "n"

represents the numeric error code. The error message remains displayed until the next key

actuation takes place.
