Figure12.1 Pictographs of the status messages
Failure: Due to a malfunction in the transmitter, a fault message is output.
This status message is always active. It cannot be deactivated by the user.
Function check: The transmitter is being worked on, the measured value is
temporarily invalid (for example during simulation).
This status message is inactive by default.
Out of specification: The measured value is unreliable because an transmitter
specification was exceeded (e.g. electronics temperature).
This status message is inactive by default.
Maintenance required: Due to external influences, the transmitter function is
limited. The measurement is affected, but the measured value is still valid. Plan in
maintenance for the transmitter because a failure is expected in the near future (e.g.
due to buildup).
This status message is inactive by default.
