Roller blind for panoramic sliding roof function - GF68.50-P-4101-01PC
Function requirements
- Circuit 15R ON or
- Circuit 15 ON
- The panoramic sliding roof is closed.
Function sequence
The following function sequence is initiated by means of the roof system switch (N70s1) or the transmitter key (A8/1) :
- Retraction of sun blind to the "open" end position.
- 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) .
