Manual Mode
In the Overview screen in Manual Mode, the pumps can be started manually by pressing the red
Start
button. Alternatively, the feed (P-01) and permeate (P-03) pumps can be put into an individual
automation loop where data from either the flow meter modulates pump speed. Access this feature
by toggling the
Manual
button to
Auto
. Only the individual control loop for that pump is activated
and the pump will run at the setpoint entered based on the feedback from the flow meter (FL-01)
for the feed pump (P-01) control or scale (WE-01) for the Aux/Diafiltration pump (P-03) control.
