3 Switch point setting
► Press button briefly and release it.
► After 1 - 2 s press it again and keep it pressed for the time indicated.
> The flow sensor gives its output signals to the teach button. They are displayed
by the illuminated pushbutton:
Output closed (OUT = 1) button lights
Output closed (OUT = 0) button does not light
Button
OUT = 1
OUT = 0
Time window
Duration [s]
Within the time windows A, B, C the output is switched depending on the flow: output closed
(OUT = 1/ button lights) if flow ≥ SP / output open (OUT = 0 / button does not light) if flow < SP.
If flow rises or falls within the time windows A, B, C the switching status / display of the illuminated pushbutton can change.
In the time windows D, E, F the output is used for feedback signals (-> table below). It does
not react to flow changes.

A Initialisation of the setting operation.
B Confirmation of the initialisation.
C Setting of the switch point (SP)*
Push of the button in s 5 10 15 20 ... 55 60 65
corresponds to SP in
cm/s
D The last switching status from C is maintained (= internal monitoring).
E Output signal is inverted (= confirmation of the setting);
duration = setting time of the selected switch point
F Output signal is inverted again (= internal monitoring), then this new switch
point is active.
* Accuracy: ± 1s
min.: flow < 10 cm/s; max.: flow > 60 cm/s
min. 10 15 20 ... 55 60 max.
