7.3 Behaviour in rotation by air current in reverse direction
In the STOP state (no release, no preset signal, no voltage supply) the motor controller
does not intervene when the fan turns in the wrong direction (e.g. due to a draught).
If the fan is started (= voltage ON), while being driven in the opposite direction to that set,
the speed is reduced controlled to
“
0
”
and restarted in the set direction of rotation.
The higher the speed to be reduced, the longer this process lasts.
Information
Do not disconnect the line voltage if, during an application, this might result in the
disconnected fan being propelled very powerfully in the reverse direction. This ensures a
safe start at all times.
