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
represents the numeric error code. The error message remains displayed until the next key
actuation takes place.
The following table shows the error codes and information regarding the failure cause and
elimination.

CAUTION!
If faults cannot be eliminated by means of the measures listed above, the

is no longer present, and it must be prevented from being inadvertently put back
into service. In this case, contact the manufacturer.
If a return is needed, follow the instructions given in chapter 12.1 "Return".
