For operation as a speed controller, the output voltage is set manually by adjusting the built-in
potentiometer, by an external potentiometer or external signal.
The desired function is determined with dipswitch

down to

(cutoff below approx. 2 % regulating variable).
Without minimum speed cut OFF (DIP 5 =

= factory setting)
•
If minimal speed
“

”
is adjusted (e.g. 20%), then no disconnection of the fan takes place.
I.e. always a minimum ventilation is ensured (fan does not go under setting
“

).
With minimum speed cut off (DIP 5 =

)
•
Cutoff below approx. 2 % regulating variable from sestting

•
Switch on again for a regulating variable above 5 % (to setting
“

).
