An error has occurred in the ADC (Analog to Digital Converter) installed
in the sensor input device.
The voltage value read from the ADC is outside the expected range.
ADC out of range fault (bit 1) or ADC hard fault (bit 6) will occur in the fourth argument InputStatus of the SsiInputTemperature function.
If a ADC fault always occurs, the following factors may be considered.
- Thermocouple is disconnected.
- Thermocouple wiring is incorrect.
- Other problems such as failure of sensor input device.
If necessary, check the system installation status.
For information about the ADC, please refer to the block diagram in [What is the cold junction compensation function?].
