Operation explanation
3.2.1 Sampling
Sampling system can take samples on three different principles:
•
Manual sample, by pushing a button on the operation panel.
•
Automatic sample, as programmed:
-
Time proportional sampling
- Volume proportional sampling(by pulse input or current input)
- Batch sampling (start time prop.sampling when the pulse
input is active).
•
Automatic sample on programmed start- and stop date.
3.2.2
Container distributor system (optional)
The distributor ensures a proper sample distribution across different
sample containers.
Systems with multiple sample containers are equipped with a direct
distributor. The distributor positions the sample hose from the sampler
(clockwise) above the container. This operates automatically (by program)
of manually (by push button). The distributor is programmable to turn on:
• Fixed time (example: set on 10:00) & selected days.
• Time interval (example every 2 hours), time interval starts after
programmed fixed time.
• After a number of taken samples, dependable on sample and
container volume (overflow protection).*
* When the distributor turns the cycle totalizer & sample counter
are reset. These values are stored in the jazz controller.
3.2.3
Cycle data (optional)
The display totalizes the cycle’s m
3
and taken samples. These values reset
when a new cycle is started (the distributor rotates to the next container).
The values are stored with the average temperature and date & time. The
controller stores up to 24 cycles.
3.2.4
Alarm function (optional for In Line Samplers)
After multiple sample failures or power failure the alarm output relay of
the sampling system closes.
When a sample cycle is not completed the CPU registers an error sample.
After a set number of error samples (default = 3) the sampler stops taking
automatic samples and switches to alarm condition. The alarm is
perceptible on 2 ways:
• A programmed output relays switches.
• Display describes current alarm status.
