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.

Sample Flow Failure
The analyzer cannot detect any sample flow.
If there is sufficient flow to the analyzer, check that:
1. 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.
