FIGURE 6-2. Rosemount 3051N 
with Optional LCD Meter.
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.
