4.2.1 Sensor Faults – Register 40005
The sensor fault status register consists of High and Low Status Bits. These bits are set/reset as faults occur or
are cleared. Each Bit has a particular meaning and displayed as follows:
Register # High Byte Low Byte
0005 Status Bits Status Bits
NOTE Bits read as 0 are FALSE, bits read as 1 are TRUE.
Status Bits High Byte:
Bit 15 – Reserved
Bit 14 – Calibration Mode
Bit 13 – Reserved
Bit 12 – Zero Fault
Bit 11 – Range Fault
Bit 10 – Reserved
Bit 9
– Clearing Fault
Bit 8 – Reserved
Status Bits Low Byte:
Bit 7 – Sensor Fault
Bit 6
– Processor Fault
Bit 5 – Memory Fault
Bit 4 – Reserved
Bit 3 – Reserved
