= 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 ” ).

•
If no “ n-min ” is adjusted, the fan stops with reaching the desired value.
•
If
“
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 ” ).

•
For PI-controller only in special applications of importance.
•
When the setpoint is reached, the modulation is reduced to “ 0 % ” , or to the set value if
“ n-min ” is speci fi ed.
•
For actual value = setpoint disconnection takes place from “ n-min ” to “ 0 ” . Hysteresis
(ON / OFF) approx. 2.5 % of 100 % set value.
8 Start-up
8.1 Prerequisites for commissioning
Attention!
1. You must mount and connect the device in accordance with the operating instructions.
2. Double check that all connections are correct.
3. The mains voltage must match the information on the rating plate.
4. The rated current on the rating plate will not be exceeded.
5. Make sure that no persons or objects are in the hazardous area.
