Dosing pump
● Press "F1" to switch to the "Dosing Pumps" menu
Display indicator:
The Hall sensor signals and the signals from the flow controllers can be checked
in this menu.
H = X, means Hall sensor signals; D = X, means flow controller signals.
NOTE The values displayed here are not identical to the
dosing stroke details from the individual dosing pumps,
e.g. 120 strokes/min because the calculation does not
relate to 1 minute.
The default changes as the installation runtime progresses, whereby the following
evaluation is decisive.
D = H; i.e. each of the Hall sensor signals from the dosing pump is
fed back by the flow controller.
D > H; more flow controller signals are fed back, i.e. if the deviation is too large,
this reduces the precision of the flow monitor, although the installation
keeps running (there is no error message).
D < H; too few dosing controller signals are fed back. The overflow installation
goes into malfunction mode. The dosing controller settings have to be
checked.
NOTE The installation is correctly set at D = H whereby a few
extra dosing controller signals (D>H) have no bearing
on the precision of the installation.
● Press "Escape" to go back.
Bypass water
● Press "F2" to switch to the "Bypass Water" menu
Display indicator:
The setpoint and actual value for the bypass water can be checked in this menu.

● The value is entered by pressing the "Up" or "Down" buttons (changing the
number) and by pressing the "Arrow left" and "Arrow right" buttons (chan-
ging the input position).
Press "F1" to switch from -XX to +600 or from +600 to -XX
● Press "Enter" to confirm the entry
● Press "Escape" to go back.
NOTE If a new installation size is set, the preset limits for the
new installation are loaded!
