10. ERROR MESSAGES
Table 10.1 List of Error Messages
11. BEHAVIOR IN ERRATIC CONDITIONS
(1) Erratic A/D Converter
If, following energization of A/D converter circuit, the conversion process is not completed within the
specified time period, it is found that the circuit has a problem. At this point, temperature and pressure
fallback values are used for calculation.
(2) Temperature and Pressure Input Out of Range
If the input exceeds the high limit or falls below the low limit, its default fallback value is used for
calculation.
(3) Analog Output Overflow
A full scale output is produced across the analog output terminals.
No.
