Safety anti-pinch
In automatic mode and at the end of its travel,
if the blind meets an obstacle while closing it
stops and moves back slightly.
Reinitialisation
If power to the blind is cut off while it is moving,
the safety anti-pinch must be reinitialised:
operate the control until the blind is fully
closed,
continue to press for at least 3 seconds.
A slight movement of the blind will then be
noticeable, confirming the reinitialisation.
If the blind stops and immediately opens again
during a closing manoeuvre:
operate the control until the blind is fully
open,
then operate the control until the blind is
fully closed.
The safety anti-pinch function is not
operational during these operations.
If the blind meets an obstacle during
operation, you must reverse the
movement of the blind. To do this, press
the control concerned.
When the driver operates the blind
control, they must ensure that no one is
preventing correct closing of the blind.
The driver must ensure that passengers
use the blind correctly.
Be aware of children when operating
the blind.
