3.1 Startup sequence

3.2 Analyzer initialization

Startup
The analyzer goes through the following sequence on power up:
1. Splash window: The splash window appears at startup while the system launches
the application.
2. Verify lamp monitor: After the system has initialized, it verifies that the lamp monitor
works by turning on the main lamp and ensuring a voltage is returned.
3. Sample bottle check: The system checks to see if the bottles loaded in the bottle
bay match the last known configuration. If the bottles contain RFID tags, the analyzer
reads the tags and compares them against the information stored in the settings. If
the RFID tag doesn't match what's stored in the settings, the settings are updated
with the new information and a warning is generated. If the settings list a non-RFID
tagged bottle in one of the bottle positions and an RFID tag cannot be detected in
that position, the analyzer assumes the bottle is still present.
4. Start sampling: If the analyzer is configured for online TOC, it starts sampling after it
has powered up.
5. Print header: After the system has started up, it prints a daily header.
With the plumbing, input, outputs and power connections properly established, the
ANATEL PAT700 can be initialized and placed into operation. Because the cleanliness of
commercially available tubing varies (particularly stainless steel), it is suggested that the
analyzer's flow path be thoroughly flushed. This is accomplished by placing the
instrument in either on-line TOC mode or self-clean mode for several hours.
To initiate the PAT700 and place in self clean mode:
1. Open the isolation valve to initiate flow to the analyzer.
2. Turn on the analyzer. The analyzer will go through the sequence described above
following power up.
3. To place the analyzer in self-clean mode, access the Run Mode screen by touching
the << tab to open the sliding toolbar.
4. Touch the run mode icon at the top of the sliding tool bar.
5. At the Run Mode dialog box, touch the self-clean icon.
6. Refer to Self clean mode, page 53
self-clean mode the analyzer's UV lamp is turned on to oxidize any contaminants
inside the analysis cell as sample water continuously flows through the analyzer to
flush away impurities. Allow the analyzer to run in this state for at least 3-4 hours, or
longer if the sample tubing is lengthy or if the sample point pressure is low.
7. With the analyzer sufficiently cleaned, on-line TOC analysis is initiated by selecting
Online TOC in the Run Mode dialog box.
Note: To ensure accurate and representative results after installation or long-term storage, allow the
instrument to complete several analyses before accepting the reported data as valid.
