Diagnostic Messages
In addition to the output, the LCD meter displays abbreviated operation, error, and warning messages for troubleshooting the transmitter. Messages appear according to their priority, with normal operating messages appearing last. To determine the cause of a message, use a HART Communicator to further interrogate the transmitter. A description of each LCD diagnostic message follows.
Error | Error messages appear on the LCD meter display to inform you of serious |
| problems effecting the operation of the transmitter. The meter displays an |
| error message until the error condition is corrected, and the analog output is |
| driven to the specified alarm level. No other transmitter information is |
| displayed during an alarm condition. |
| FAIL |
| The transmitter CPU board and the sensor module are incompatible. If you |
| encounter this message, contact Rosemount Nuclear Instruments, Inc. at |

| FAIL MODULE |
| The sensor module is disconnected or is malfunctioning. Verify that the |
| sensor module ribbon cable is connected to the back of the electronics board. |
| If the ribbon cable is properly connected, there is a problem within the sensor |
| module. Possible sources of problems include: |
| • Pressure or temperature updates are not being received in the sensor |
| module. |
| • A |
| operation has been detected in the module by the memory verification |
| routine. |
