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.
The following table shows the error codes and information regarding the failure cause and
elimination.
Error code Description Causes
1 Transmitter does not respond
2 Communication error ■ Parity, check sum, package length incorrect
upon receiving
■ Transmitter signals receive error
3 Command not implemented Command not supported by the transmitter
4 Range error ■ The value is outside the range supported by the
sensor
■ The desired unit of measure is not supported
5 Unspecified error of the
transmitter
The sensor signals an error in the status byte that
is not broken down
CAUTION!
If faults cannot be eliminated by means of the measures listed above, the
instrument must be shut down immediately, and it must be ensured that signal
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".
