Activating/deactivating the upper anti-freeze mechanism
Open/close the shading solution to a point between the limit positions.
Press the programming button on the programming unit (for approx 10 s) until the tu-
bular drive confirms.
Obstacle detection
Caution
Please note that the drive must be pushed into the shaft as far as the band of the thrust
ring.
Obstacle detection is not activated with a vertical fabric shade.
Use of the drive’s obstruction detection system as personal protection is not permitted. It
has been designed exclusively to protect the roller shutters or sun protection system from
being damaged.
If the drive is correctly installed, it switches off when it detects obstructions or roller shutter faults and reverses a short way in the
opposite direction and thus away from the obstacle.
If reversing is interrupted, a further drive command is only possible in the direction of reversing. Run the shading solution without
interruption until the tubular drive stops automatically. It is now possible to travel in both directions again.
The following are detected:
Moving DOWN
•
A curtain jam when closing due to objects on the window sill or sticking of the lateral guide tracks.
If the tubular drive switches off in the area of the upper limit position, it checks once more
whether an obstacle is present.
To ensure complete closing of the roller shutter curtain at the lower limit position, the curtain does not reverse once it gets to ap-
prox. 360° from the lower limit position.
Moving UP
• Extremely large increase in the load (e.g., ice on the end strip)
To ensure that the roller shutter curtain safely enters the guide tracks, obstruction detection is inactive for approx. 1.5 revolutions
of the barrel from the upper limit position.
Fly screen protection function
Attention
The fly screen protection function is not activated with a vertical fabric shade.
If the fly screen protection function is activated, obstruction detection is activated after a revolution of the barrel of approx. 140°
from the upper limit position. If the roller shutter curtain meets an opened fly screen door, the drive stops and returns to the upper
limit position.
This function is deactivated on delivery.
Both limit positions must be set before the fly screen protection function can be activated.
Activating/deactivating the fly screen protection function
Open the shading solution to the upper limit position.
Now press the travel button downwards and within 1 second press the programming
button too.
The tubular drive confirms.
