Measured value status
The measured value status is available for the main and secondary
measured value of a sensor.
05h MAINTENANCE The sensor is in maintenance condition or a cleaning cycle is active
(cleaning including adjustment phase).
The measured value display on the terminal indicates a flashing
measured value or Clean.
During the sensor status MAINTENANCE, the measured value and
the measured value status is frozen.
In the case of the measured value status VALID, the measured value
is frozen on the value of the start of the MAINTENANCE status.
Code Status Meaning of the status
Code Status Meaning of the status
1h VALID The measured value is valid.
In the case of the sensor status MAINTENANCE, the measured
value is frozen on the value of the start of the MAINTENANCE sta-
tus.
The measured value display on the terminal indicates a flashing
measured value or Clean.
2h OFL The measured value lies outside the selected measuring range.
The transmitted measured value is set to 0.
The measured value display on the terminal indicates OFL.
3h INVALID The measured value is invalid.
The transmitted measured value is set to 0.
The measured value display on the terminal indicates "----" (invalid
measured value).
4h MISSING The measured value cannot be determined or is not available.
The transmitted measured value is set to 0.
The measured value display on the terminal indicates Cal or Error.
