Power window excess force limiter, function - GF72.29-P-3014GZ

MODEL 164.1/8 

Excess force limiter (indirect obstruction sensor) 

Function requirements 

Function 

If the left front door control unit (N69/1), right front door control unit (N69/2) and front SAM control unit (N10) recognize pinching while automatically raising a window, the drive is reversed and the window opens approx. 70 mm.

An excess force limiter for the vent window (model 164.8) is realized via the left vent window obstruction sensor strip (B51/5) and right vent window obstruction sensor strip (B51/6) which is read in directly by the rear SAM control unit (N10/8).When pinching is recognized, the corresponding vent window reverses direction and is automatically and completely opened.

The vent window drive is not normalized or denormalized.

If a request is received by the front left power window motor (M10/3) for another automatic closing operation within 5 t 10 s, this operation is performed without obstruction sensor.

Adaptive excess force limiter for power window 

Function requirements 

Function 

The adaptive excess force limiter serves for recognition of sluggishness when the window rolls up and takes this into consideration the next time it is actuated. The adapted values are not erased by normalization nor by voltage loss.
