Planning and application
Measuring slat adjustment total travel time
The total travel time of the slats from opened (horizontal slat position) to closed (vertical slat position) is
easy to determine: Fully open the slats. Then count how many slat adjustments are necessary to fully
close them. The slat adjustment total travel time is the number of slat adjustments multiplied by the switch
on duration. Enter this value as a parameter.
Reversing time, pause between two movements
To ensure that the blind drive is not damaged by a sudden change in direction, the output contacts are
electrically disconnected for the duration of the parametrized reversing time and only switched for the
required direction of movement once this time has elapsed.
Important
Observe the drive manufacturer's technical data when parametrizing the reversing time!
Note
The output contacts for UP and DOWN travel are configured to be electrically mutually exclusive,
ensuring that voltage cannot be applied simultaneously to both contacts, which would damage or
destroy the drive.

Safety

Activating the Safety on the Blind/Roller Shutter Actuator determines whether the blind should move UP,
DOWN, STOP or remain unchanged.
When the Safety is rescinded, the blind is moved to the parametrized position.
The Block function is suitable, for example, to raise blinds and shutters when windows have to be cleaned.
Please note that the Safety alone is not sufficient to protect cleaning personnel from the blinds
descending. Adequate protection should be guaranteed by another means.
