Power Window Safety Function

When the driver or passenger power window auto-up switch is operated, the power window safety function is activated

1.	Safety function enable conditions When the window is closing and restriction 100N (using the 10N/mm spring) has been detect causing the motor to slow down, the window is reversed.

Window reversing distance (except while holding the Auto-Up switch).

–	When jamming (resistance) is detected between 4 - 250mm from the top of the door. → the window is lowered to 300mm from the top of the door as shown below.

–	When jamming (resistance) is detected from more than 250mm from the top of the door. → the window is lowered to the lowest position plus an additional 50mm from the lowest position.

Window reversing distance (while holding the Auto-Up switch)

–	When jamming (resistance) is detected while pulling the auto-up switch. → Window moves downward by 25mm from jamming position

–	Auto-up function is not available for 5 seconds after the above operation. → When pulling the auto-up switch, the manual-up function is activated (no safety function).

4.	The area with the safety function is not applied Safety function is not available within the 4mm range from the top of the window frame.

How to initialize the safety power window

Battery connection initialization

When the battery power is removed for more than 5 minutes, safety power window switch needs to be re-initialized.

(1)

Power window operation before initializing

–	Manual-Up/Down function is available

–	Auto-Up/Down function is not available (Only up/down available while holding the switch)

(2)	Initialization With the window in the FULL OPEN position, press and hold the UP switch position until it fully closes and hold switch for an additional 0.2 seconds. (Procedure will fail if starting initializing with the window in closed position)

(3)	If initializing procedure while the safety system still in jamming status, the safety function is not available.

(4)	The window safety motor uses a hall type sensor that is used to verify the position and direction of the motor, the safety module detects the uppermost (full closed)position of the window and sets the position as "0" or full closed.

(5)

De-initialization

The window safety module is de-initialized if the conditions listed below occur. Auto-Up and Safety function are deactivated.

De-initialization conditions

a.	Repeating window downward movement 15 or more times in a row.

b.	Power supply is suspended while the motor is in operation.

Driver door opens, IGN Off with the window glass positioned in Hard Stop -> IGN On within 2 seconds -> within 5 seconds with IGN On, entering manual down switch signal 3 times -> De-initialization completed (if power is not on in 2 seconds, or the operation to be performed in 5 seconds, the de-initialization process shall be repeated from the beginning.)

Fail safe mode initialization

System includes motor overheating prevention feature, avoid overrunning/overheating of the window motor.(EEPROM data is stored in safety module)

(1)	If the window moved by force and motor has a problem, power window switch could enter in fail safe mode for user’s safety.

(2)

Power window operation in fail mode

–	Auto/Manual-Down function is available

–	Auto/Manual-Up function is not available (When Auto/Manual-up is operated, window rises by 20mm and stops moving.)
