Stirrer P2 and pump P3 start.
Raw water flows through the system and the liquid polymer is also
metered in.
The automatic preparation process starts
Motorised valve V3 opens automatically and V2 remains closed
Polymer solution production
The "Polymer preparation" output signal is immediately enabled
depending on the output of the system: after approx. 15 minutes at
400 l/h and after approx. 30 minutes at 200 l/h.
The control valve VC1 automatically adjusts the raw water volume to
the mixing and preparation chamber.
Setpoint and measured value converge after a delay time.
When post-dilution is installed, the max. output of 400 l/h of the pre‐
pared polymer solution is taken from the main line and the remaining
volume of raw water is automatically adjusted using the control valve
VC2.
INFO!: With the Comfort version of system, the following pre-set
values can be changed via the "Parameter / Process" tab,
