Bottle Mode
6.10 Excursion mode
Note: Excursion mode requires the use of an RFID tagged excursion bottle. Excursion mode does
not operate without an RFID tagged excursion bottle.
Excursion mode enables the analyzer to withdraw a sample from the water system when
a predefined TOC level is exceeded or when alarm condition 35 or 36 occurs. An
excursion sample can also be implemented manually. With excursion mode enabled and
an empty excursion sample bottle loaded, a sample of the process system water is drawn
immediately following the indication of the appropriate event. The water sample is then
available for analysis to help determine the cause of the water system excursion.
Excursion sample bottles must contain an RFID tag. The information from the excursion
event is written to the bottle's RFID tag to ensure accurate information about the water
sample.
Excursion with validation includes the use of a 500 ppb sucrose standard with the
excursion sample bottle. The 500 ppb standard is used for verifying the performance of
the analyzer immediately following the excursion event and sample. If excursion with
validation is enabled, the analyzer draws a water sample, immediately following the
analysis that indicated an excursion, followed by an analysis of the 500 ppb standard.
Touch the excursion mode button in the bottle mode dialog box. See Figure 67, page 88.
The excursion mode dialog box appears, as illustrated in Figure 91.
Excursion with validation button opens the excursion with validation load bottles dialog
box. See Figure 92 and follow the instructions in Excursion with validation, below.
Excursion without validation button tells the analyzer to run the excursion without
validation and opens the excursion without validation load bottles dialog box. See
Figure 96 and follow the instructions in Excursion without validation, page 113.
Return icon returns you to the bottle mode dialog box.
