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.
