BLZZRD Portable Refrigerated Sampler
Section 5 Extended Programming
5-31
If you select COMPLETE SAMPLES, the sampler sends a
three-second pulse only after it successfully collects a sample.
The sampler will not send an event mark if an error occurs, such
as “No Liquid Detected.”
Figure 5-5 Event Mark Timing Diagram
If you select EVERY SAMPLE, the sampler will send an event
mark every time a sample is initiated. The event mark signal can
be a:
• 3-second pulse at the beginning of the pre-sample purge.
• 3-second pulse at the beginning of forward pumping
only, marking the time the sampler deposited the
sample.
• Variable duration pulse generated during the pump
cycle, from the beginning of the pre-sample purge to the
end of the postsample purge.
• Variable duration pulse generated only during forward
pumping.
Figure 5-5 shows event mark timing diagrams.
Bottle Number – Concurrent with the event mark, the sampler
also sends a bottle number signal. The bottle number signal is a
series of pulses. The number of pulses sent represents the bottle
currently accepting a sample (see Figure 5-5).
5.15.8 Pre-sample and
Post-sample Purge
Counts
The pre-sample purge is when the pump runs in reverse clearing
the strainer of any debris before taking a sample. The pre-sample
purge is set at 200 pump counts. After the sample is taken a
post-sample purge occurs to clear the liquid from the suction line.
