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
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
the first corrective action and then try the second.

OUNDATION
Description
Wrong sensor connection with wrong sensor type
The micro detected a chksum or start/stop bit failure with
ASIC communication
The ASIC detected a communication error
ASIC interrupts are too fast or slow
Reference resistors are greater than 25% of known value
ASIC registers were not written correctly. (Also
CALIBRATION_ERR)
Difference between sensor values has exceeded user specified
limit
The device is currently operating in Hot Backup mode,
meaning the primary sensor has failed
Open sensor detected
Shorted sensor detected
Open or shorted PRT detected
Sensor readings have gone beyond PRIMARY_VALUE_RANGE
values
Sensor readings have gone below 2% of lower range or above
6% of upper range of sensor
