3.3.3 ANALOG
Flow related sampling 0/4 - 20 mA. The sampler is controlled by a mA - signal, where mA is proportional to the
flow. Accumulating of the flow is performed and when accumulated flow = pre-set interval, the sampler takes a
sample.
3.3.4 MAX FLOW
Setting of max. flow can be done between:
♦
1.000 - 9999 m
3
/ h
3.3.5 INTERVAL
Setting of interval (m
3
between samples) can be done between:
♦
1.000 - 9999 m
3
/sample
NOTE! Max flow (m
3
/h) / interval (m
3
/sample)
≤
36.0 samples / h
3.3.6 MAN SAMPLE
Manual sampling, a sample is taken at the operators command.
3.3.7 TOTAL SAMPLES
Every correct sample (without error) is accumulated.
3.3.8 ALARM
When an error appears the red diode at
ALARM lights up
At serious errors the display flashes and the error has to be accepted (and corrected) before sampling can
continue.
The alarm function (E-02) can be turned off by the ALon/ALoF-function.
ALon: (alarm on), the alarm output is activated when there is no water in the sample bottle during sequence 03.
ALoF: (alarm off), the alarm output is not activated even if the bottle stays empty.
Alarm output
Alarm output for connection to an external alarm unit, flash bulb, siren etc. Max load: 24 VDC.
The alarm output, a potential free contact, is closed as long as the error remains.
