Function

The sun blind is opened by pushing the roof system switch (N70s1) back to the actuation point. The overhead control panel control module (N70) reads the state of the switch and actuates the sun blind motor (M24m1) for as long as the switch is activated or until the sun blind has reached its end position.

 Further actuation is only possible once the control module senses that the switch is in the neutral position (i.e. not activated for more than 1 second).

Function abort

If the overhead control panel control module (N70) detects lock-up, the "open sun blind" function is aborted.

When denormalized, the "open sun blind" function is restricted. Motor actuation is then only possible for at most 1 second. The switch must then be released and pressed again before another actuation can take place.
