GF72.29-P-3007T Power Windows With Automatic Raising/Lowering, Function

GF72.29-P-3007T Power Windows With Automatic Raising/lowering, Function

Function prerequisites
^ No overvoltage or undervoltage
^ Circuit 15 ON or circuit 15R ON.
^ Power window in normalized state (for automatic raising).
^ Function disabled (version coding).
^ Power window motor rotation direction correct
^ No Hall sensors defective.

Function
The automatic raising/lowering function is performed by briefly pulling back or pushing forward a power window switch in the "close" or "open" direction beyond the first click-stop position. The corresponding door control module reads in the switch status and then actuates the corresponding power window motor until the position recognition indicates that the window is completely closed or open.

Automatic raising
The "automatic raising" function effects automatic window raising with excess force limitation (obstruction sensor) and can only be performed on normalized windows. If no other switch position is detected, the window is fully closed as far as the upper block position.

If an incorrect rotation direction of the power window motor or a defective Hall sensor is recognized, the automatic raising function is interrupted immediately.

If an error (incorrect rotation direction, defective Hall sensor) is recognized or when the windows are denormalized, the system will respond to any continued request for "automatic raising" by actuating the "manual raising" function.
If the "manual raising" function is detected after recognition of the "automatic raising" function without previously detecting the non-actuated state, then the "automatic raising" function remains active.

Function abort
The "automatic raising" function is aborted if:
^ Function requirements are not satisfied
^ An obstruction is detected
^ Another switch position after neutral position is detected
^ Response from excessive force limitation (obstruction sensor)
^ Activation time exceeded t >25 s
^ Zero point tolerance exceeded

Automatic lowering
The "automatic lowering" button function effects automatic window lowering and can be performed without normalization.

As long as no other switches are recognized, the window is completely opened down to the lower end stop position

Function abort
The "automatic lowering" function is aborted if:
^ Function requirements are not satisfied
^ Another switch position after neutral position is detected
^ An obstruction is detected
^ Activation time exceeded t >25 s
^ The maximum travel distance for normalized windows is exceeded
