Setup Channels Option
This menu selection gives access to pump settings as follows:
Ideal Typical Flowrate 0.8 to 1.2L/Min
Use the pressure
indication to:
1. Check pump suction
performance by blocking
the inlet line. Minimum
should be a 25mBar
pressure drop.
2.Use to observe the
system running
pressure, typically
10mBar Pressure drop
with new filters.
Sampler low flow threshold. Set this to be 5mBar below maximum pump suction
pressure with the sample line blocked. For example with new internal and EOL filters
fitted the running pressure is 990mBar. With filters removed the running pressure is
1002 mBar. So the filters and sample line impose a 12mBar pressure drop. The
maximum pump suction performance with the line blocked is 967mBar indicating a
25mBar max suction pressure. In this case set the low flow threshold to 20mBar.
Use to turn pump on/off
Use to view pump running
pressure difference on to off
and to ensure pump starts
correctly after tuning
Tune function will
automatically set the pump
optimum operating
frequency.
Manual pump adjustment to
fine tune using attached
flowmeter. Use test or On/Off
buttons to ensure pump reliably
starts after tuning.
