Lock-up recognition function - GF68.50-P-2005PC

MODEL 203.7 with CODE (413) panoramic sliding roof 

Panoramic sliding roof lock-up recognition function 

The overhead control panel control module (N70)  receives the voltage pulses sent by the two Hall sensors on the sun blind motor (M24m1), Hall sensor 1 (M24b1)  and Hall sensor 2 (M24b2)  , and uses this data for position measurement  .

If no Hall sensor pulses are received for more than 0.2 seconds during sun blind actuation the drive unit is deactivated.

Hall sensor failure represents a denormalization  .

The sun blind can then only be closed in increments of t = 160 ms by means of the roof system switch (N70s1)  , or alternatively by using the emergency crank.

Overload protection is provided by a mechanical thermal circuit breaker installed in the sun blind motor (M24m1)  .
