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 Field
Communicator or AMS to further interrogate the transmitter. A description of each LCD
diagnostic message follows.
Error
Error messages appear on the LCD display to inform you of serious problems affecting the
operation of the transmitter. The LCD 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. See
procedures" on page
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:


Some non-volatile memory faults are user-repairable. Use a Field Communicator 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, you must replace the transmitter.
Fail Elect
The transmitter electronics board is malfunctioning due to an internal fault. Some of the FAIL
ELECT errors are user-repairable. Use a 275 Field Communicator 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, you must replace the electronics board. See
procedures" on page
Fail Config
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 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.
92
97.
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.
