4.3.4 Mapping of DIAGNOSIS_EXTENSION bits into DIAGNOSIS bits
How to read this table:
If e.g. an S - Temperature Drift error has been detected the below-mentioned
DIAGNOSIS_EXTENSION bits will be set:
• DIAGNOSIS_EXTENSION (Octet 1 / Bit 2): S - Out Of Specification
• DIAGNOSIS_EXTENSION (Octet 4 / Bit 4): S - Temperature Drift
These bits will be mapped to the below-mentioned DIAGNOSIS bits (which will be set
additionally):
• DIAGNOSIS (Octet 2 / Bit 5): DIA_MAINTENANCE
• DIAGNOSIS (Octet 4 / Bit 7): EXTENSION_AVAILABLE
5 0 S - Tube Temperature Temperature is exceeding limits
1 S - Density Process density is over range
2 S - Startup The device is in startup mode
3 S - Power Fail Device has been powered up
4 S - Resistor Circuit Defective Temperature and strain measurement defective
5 S - SE Defective "Operational fault in sensor electronics"
6 S - 2 Phase Flow 2 phase signal is above the programmed threshold
7 S - Density Calib. Failed Density calibration failed
6 0 S - BE PCB Temperature Temperature on BE PCB is exceeding maximum limit
1 S - Interface PCB Fault Error detected during self-monitoring of interface card
