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 Model HC275 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.
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 not disconnected, 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–this condition is
not repairable, the transmitter must be replaced
FAIL ELECT
The transmitter electronics module is malfunctioning. Possible causes include:
Internal fault
A non-volatile memory fault that will effect transmitter operation has been
detected in the module by the memory verification routine
Neither problem is user-repairable; you must replace the electronics board.
