Roller Blind For Panoramic Sliding Roof

Function requirements
- Circuit 15R ON or
- Circuit 15 ON
- The panoramic sliding roof is dosed.

Function sequence
The following function sequence is initiated by means of the roof system switch (N70s1) or the transmitter key (A8/1):
1 Retraction of sun blind to the "open" end position.
2 Extension of sun blind to the "closed" end position.

The sun blind is driven by the sun blind motor (M24m1). The motor's direction of rotation for sun blind retraction and extension is determined by the polarity of the actuating voltage from the overhead control panel control module (N70). The polarity of the actuating voltage is set by means of a two-coil relay (center-zero relay with neutral position).

Position measurement is performed by the overhead control panel control module (N70) using pulses supplied by Hall sensor 1 (M24b1) and Hall sensor 2 (M24b2).
