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

 

(952) 949-5210 if you need assistance.

 

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 non-volatile memory fault that will effect transmitter

 

operation has been detected in the module by the memory verification

 

routine.
