FLOW-PROPORTIONAL SAMPLE EXTRACTION
According to the output signal of your flow meter either the
operating mode flow analog or flow digital can be selected
in the program settings.
FLOW ANALOG – set resp. calibrate -
Under „SETTINGS“ -> „SAMPLER SETTINGS ->ANALOG
SIGNAL“ the analog input can be set to the default values
4-20 or 0-20 mA or it can be adjusted/calibrated to the
plant’s signal.
To ensure that the sample extraction is effected according
to the plant’s signal we recommend a calibration.
Calibration
of the analog input 0/4-20 mA:
Connect the sampler to the plant’s signal. Set 0/4 and
20 mA by means of the SPS or an analog signal transmitter
and confirm these values according to the menu instructions.
1.
Connect 0/4 mA and confirm.
2.
Connect 20 mA and confirm.
3.
Calibration OK, confirm.
FLOW ANALOG
The only difference between the programming of the flow
analog mode and the flow digital mode is the definition
of the sampling interval. Point of reference in the flow
analog setting is the maximum flow at 20 mA, which can be
set as l/s or m3/h.
FLOW DIGITAL
In the FLOW DIGITAL mode, the sampling interval results
from the incoming pulses. The filling time can either be
time-related
or related to a
certain number of samples
. If
time-related
is selected there is a further menu to limit the
number of samples (samples/bottle) to avoid overfilling
(overfill protection).
