12 Diagnostic Information and Icons
12.1 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.
All diagnostic messages displayed on the analyzer are added to
the analyzer's audit log.
Table 12.1 shows icon types, diagnostic messages and
ON / OFF status for the fixed relays, all of which operate in the
fail-safe condition.
Note.
The diagnostic icons in the following table conform to
NAMUR 107.

the float is located in the side-sample pot and is unrestricted.
2.
the end cap of the side-sample pot is positioned to allow the
magnetic float to be within the area of operation of the reed switch.
3.
the float switch lead is connected correctly to the interconnection
board.
4.
the magnetic reed switch is operating correctly.
