SENSOR TRANSDUCER BLOCK

Table 5-5. Sensor Transducer Block BLOCK_ERR messages

Table 5-6. Sensor Transducer Block XD_ERR messages

This section describes error conditions found in the Sensor Transducer Block. Read Table 5-5 through Table 5-7 to determine the appropriate corrective action.

Condition Name and Description

Other

Out of Service: The actual mode is out of service.

Condition Name and Description

Electronics Failure: An electrical component failed.

I/O Failure: An I/O failure occurred.

Data Integrity Error: Data stored in the device is no longer valid due to a non-volatile memory checksum failure, a data verify after write failure, etc.

Algorithm Error: The algorithm used in the transducer block produced an error due to overflow, data reasonableness failure, etc.

Diagnostics

Table 5-7 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 Table 5-7. Start with the first corrective action and then try the second.
