Table E.4—Transducer Error (XD_Error) and Block Alarm Codes
Value Error Description
16 Unspecified error Indicates occurrence of unidentified error
17 General error Error cannot be classified as one of the following errors
18 Calibration error Error occurred during calibration of the device or calibration error
detected during device operation
19 Configuration error Error occurred during configuration of the device or configuration
error detected during device operation
20 Electronics failure Electronic component has failed
21 Mechanical failure Mechanical component has failed
22 I/O failure I/O failure has occurred
23 Data integrity error Data stored within the system may no longer be valid due to non-
volatile memory checksum failure, data verify after write failure,
etc.
24 Software error Software has detected an error. Possible causes: improper
interrupt service routine, arithmetic overflow, watchdog timer, etc.
25 Algorithm error Algorithm used in the transducer block produced an error.
Possible causes: overflow, data reasonableness failure, etc.
Control Registers
The Control Registers allow specific functions to be implemented via the communications port.
Table E.5
shows the value to be written to the control register to implement the desired function.
