GF72.29-P-3014RT Power Window Excess Force Limiter, Function

GF72.29-P-3014RT Power Window Excess Force Limiter, Function
- up to model year 08


Excess force limiter (indirect obstruction sensor)

Function requirements
^ Windows normalized
^ Function in a range of 230 mm to approx. 3 mm of window opening
^ The power window switches are in the non-actuated position.

Function
If the left door control unit (N69/1), right door control unit
N69/2(N10) and front SAM control unit recognizes pinching during automatic raising of the window, the drive is reversed and the window opens approx. 70 mm

Excess force limiter of the vent window is realized via the obstruction sensor strip on the left vent window (B51/5) and the obstruction sensor strip on the right vent window (B51/6), which is read in discretely by the rear SAM control unit (N10/8).If pinching is recognized, the corresponding vent window reverses direction and is automatically and completely opened.
The vent window drive is 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 windows

Function requirements
^ Windows normalized
^ Function in a range of 230 mm to approx. 3 mm of window opening

Function
The adaptive force limitation is intended to detect whether the window is hard to raise and take into consideration for further actuation.The adapted values are not erased by normalization nor by voltage loss.
