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 il-
luminated 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.

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
