Diagnostic Messages

a.If Yes is selected, proceed to Step 10.

b.If No is selected, repeat Step 8.

10.Click Next at the “Setting fld dev output to 20mA” screen.

11.Repeat Step 8 - Step 9 until the reference meter equals the transmitter output value.

12.Select Next to acknowledge the loop can be returned to automatic control.

13.Select Finish to acknowledge the method is complete.

In addition to output, the LCD display displays abbreviated operation, error, and warning messages for troubleshooting. Messages appear according to their priority; normal operating messages appear last. To determine the cause of a message, use a HART Communicator or AMS to further interrogate the transmitter. A description of each LCD 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, and analog output is driven to the specified alarm level. No other transmitter information is displayed during an alarm condition.

FAIL MODULE

The transmitter is malfunctioning. Possible sources of problems include:

•Pressure or temperature updates are not being received in the Transmitter.

•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 HART Communicator or AMS to diagnose the error and determine if it is repairable. Any error message that ends in “Factory” is not repairable.

FAIL CONFIG

A memory fault has been detected in a location that could effect transmitter operation, and is user-accessible. To correct this problem, use a HART Communicator or AMS 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.

PV LIMIT

The process variable read by the transmitter is outside of the transmitter’s range.
