4.6.1 Sensor transducer block diagnostics
Tab le lists the potential errors and the possible corrective actions for the given values. The
corrective actions are in order of increasing system level compromises. The first step should
always be to reset the transmitter and then if the error persists, try the steps in Tab le . Start with
the first corrective action and then try the second.
Table 4-5. Sensor Transducer Block BLOCK_ERR messages
Condition name and description
Other
Out of Service: The actual mode is out of service
Table 4-6. Sensor Transducer Block XD_ERR messages
Condition name and description
Electronics Failure: An electrical component failed
I/O Failure: An I/O failure occurred
Software Error: The software has detected an internal error
Calibration Error: An error occurred during calibration of the device
Algorithm Error: The algorithm used in the transducer block produced an error due to overflow, data
reasonableness failure, etc.
Table 4-7. Sensor Transducer Block STB.SENSOR_DETAILED_ STATUS messages
STB.SENSOR_DETAILED_STATUS Description
Invalid Configuration Wrong sensor connection with wrong sensor type
ASIC RCV Error The micro detected a chksum or start/stop bit failure with
ASIC communication
ASIC TX Error The ASIC detected a communication error
ASIC Interrupt Error ASIC interrupts are too fast or slow
Reference Error Reference resistors are greater than 25% of known value
ASIC Configuration Error ASIC registers were not written correctly. (Also
CALIBRATION_ERR)
Drift Alert Difference between sensor values has exceeded user specified
limit
Hot Backup Active The device is currently operating in Hot Backup mode,
meaning the primary sensor has failed
Sensor Open Open sensor detected
Sensor Shorted Shorted sensor detected
Terminal (Body) Temperature Failure Open or shorted PRT detected
Sensor Out of Operating Range Sensor readings have gone beyond PRIMARY_VALUE_RANGE
values
Sensor beyond operating limits Sensor readings have gone below 2% of lower range or above
6% of upper range of sensor
