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 S1 .

)
For operation as a P-controller the actual value measured by the sensor is compared with the nominal
value that has been set. The output voltage and hence the rotational speed of the connected motor
automatically change as a function of the parameter settings.
The desired function is determined with dipswitch S1 .

7.5 Minimum speed cut off DIP 2
7.5.1 For mode Speed controller 1.01
If no “ n-min ” is adjusted,output voltage goes continuously with reduction of the regulating variable
down to “ 0 ” (cutoff below approx. 2 % regulating variable).
Without minimum speed cut OFF (DIP 2 =
|
OFF
|
= factory setting)
•
If minimal speed “ n-min ” 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 “ n-min ” ).
With minimum speed cut off (DIP 2 =
|
ON
|
)
•
Cutoff below approx. 2 % regulating variable from sestting “ n-min ” to “ 0 ” .
•
Switch on again for a regulating variable above 5 % (to setting “ n-min ” ).
