Diagnostic Messages - Emerson Rosemount 3051S Series Reference Manual

Reference Manual

Note
After sensor trimming Rosemount 3051S Range 4 and 5 Transmitters for high differential pressure
applications, verify the 4 and 20 mA points are at the correct values using the Field Communicator. For
the example above, this would be 500 and 1500 respectively. The zero effect can be eliminated by doing
a zero sensor trim at line pressure after installation without affecting the completed calibration.

Diagnostic messages

In addition to output, the LCD displays abbreviated operation, error, and warning messages for trouble-
shooting. Messages appear according to their priority; normal operating messages appear last. To
determine the cause of a message, use a Field Communicator or AMS Device Manager to further
interrogate the transmitter. A description of each LCD display diagnostic message follows.
Error indicator
An error indicator message appears on the LCD display to warn of serious problems affecting the
operation of the transmitter. The meter displays an error message until the error condition is corrected,
"ERROR" appears at the bottom of the display, and analog output is driven to the specified alarm level.
No other transmitter information is displayed during an alarm condition.
Fail module
The SuperModule is malfunctioning. Possible sources of problems include:
Pressure or temperature updates are not being received in the SuperModule.
A non-volatile memory fault that will affect transmitter operation has been detected in the module by
the memory verification routine.
Some non-volatile memory faults are user-repairable. Use a Field Communicator or AMS Device Manager
to diagnose the error and determine if it is repairable. Any error message that ends in "Factory" is not
repairable. In cases of non-user-repairable errors, replace the SuperModule. See
procedures" on page
Fail configuration
A memory fault has been detected in a location that could affect transmitter operation, and is
user-accessible. To correct this problem, use a Field Communicator or AMS Device Manager to
interrogate and reconfigure the appropriate portion of the transmitter memory.
Warnings
Warnings appear on the LCD display to alert you of user-repairable problems with the transmitter, or
current transmitter operations. Warnings appear alternately with other transmitter information until the
warning condition is corrected or the transmitter completes the operation that warrants the warning
message.
LCD update error
A communications error has occurred between the LCD display and the SuperModule. Verify the LCD
display is firmly seated by squeezing the two tabs, pulling the LCD display out, making sure the pins are
in the feature board and snapping the LCD display aback into place. If this does not clear the error,
replace the LCD display.
