Via total duration for slat turning: This method for determining the slat adjustment times is particularly
suitable when high blind/shutter control accuracy is required, e.g. for slat adjustment. Firstly, the time
must be determined which the slat requires to tilt from fully closed (100 %) to fully open (0 %). When
the total slat turning duration has been determined, only the number required slat adjustments for a
complete slat tilt from closed to open must be input. The device calculates the slat adjustment duration
automatically.
Example
Total duration for slat turning:
Number of slat adjustments:
Time for slat adjustment (stepped) =
Note
As times under 50 ms cannot be processed, the calculated time (quotient of the total duration for slat
turning and the number of slat adjustments) must always be greater than 50 ms.

The following parameters appear:
Duration to turn slat from 0% - 100%
in ms [50...60,000]
50...1500...60,000
Options:
The measured total duration for slat turning is entered here. The time must be determined as
precisely as possible to achieve the best possible result for slat position.
Number of slat adjustments
(from 0% = open to 100% = closed)
1...7...60
Options:
This parameter defines the number of slat adjustments which are required to tilt the slats from fully
closed to fully open. The appropriate duration for a slat adjustment is calculated from the duration of
a complete slat turn and the desired number of slat adjustments.
