B.1 Analyzer Diagnostic Information
The analyzer is programmed to display diagnostic messages to
provide information on servicing requirements and any other
conditions that develop during operation. The following tables
list icon types, diagnostic messages, relay status (on or off) and
any operations that are inhibited if the condition occurs.
Diagnostic icons conform to NAMUR 107.
The messages listed below are shown by icon type and then
alphabetically. All diagnostic messages displayed on the
analyzer are added to the analyzer's audit log.
Note. The 'Out of Service' relay has the following fail-safe
operation:

Normal operation – ON (energized)

Out-of-Service state – OFF (de-energized)
