Diagnostic Messages

Summary
The diagnostic messages can be grouped into one of these three categories:
Critical Failures
Non-Critical Failures
Communication Errors
A description of the messages in each category is given in the following paragraphs.
Critical failures
Table 48 summarizes the critical communicator status message displays. A critical failure drives the
transmitter's output to its failsafe direction—upscale or downscale.
INVALID DATABASE
CHAR PROM FAULT
SUSPECT INPUT
DAC DIODE FAULT
NVM FAULT
RAM FAULT
PROM FAULT
PAC FAULT
Once a critical fault has been corrected, you must clear the critical status from the transmitter. See Clearing
Critical Status later in this section.
