Description of the operation of the system for partial opening of the window
The door is considered to be closed when the lock is at the second notch
In this situation, the window is mounted in the body seal; its position is defined as being at the Upper Limit
Following operation of the door handle (inside or outside), and at the start of opening of the door, the window lowers by 8±5 mm (so-called Partly Open position) the door can then be fully opened
If the window is operated, with the door open, the window will only close as far as the Partly Open position
After closing the door, the window closes to the Upper Limit position
In some cases (no battery current, etc.), partial opening of the window will not be possible great care must then be taken when opening or closing the door
The lowest point reached by the window is called the Mechanical Lower Limit
During normal operation, the control electronics stop the window mechanism motor before the mechanical limit is reached, in order to reduce operating noise; this is called the Computerised Lower Limit

Возможности
Открывание двери: the window will partly open if its starting position is between the upper limit and the partial opening position; the door open switch triggers this operation
Закрытие двери: the window closes if its starting position is the partly open position, it remains open if it starts in any other position
Window control: the windows are controlled in the conventional manner, with the ignition on, by two-position switches with improved user safety (closing is by pulling, and no longer by pushing which could occur by accident; pushing will open the window, which is not considered to be dangerous)
There are two switches on the driver■s side, only one on the passenger's side
The first position controls manual closing (or opening), which stops when the control is released
The second position triggers one-touch (or automatic) control (during one-touch opening or closing, any operation of a switch will stop the window concerned)
If, on the other hand, the ignition is switched off during one-touch opening or closing, the movement will be completed
Window control (открытые двери): use of the window controls has the same effects as previously, but the window will not close further than the partly open position
Locking the doors using the remote control: the windows do not change position
Блокировка замков дверей (с помощью ключа): the windows do not change position
Deadlocking using the remote control: deadlocking using the remote control triggers closing of the two windows with safety auto-reverse as soon as deadlocking of the vehicle is active
Суперблокировка (с помощью ключа): deadlocking using the key triggers closing of the two windows with safety auto-reverse after the position of the key has been maintained for at least 1-2 seconds (±0,2); the window closes as long as the position of the key is maintained
Special features of the safety auto-reverse
Принцип
When the window mechanism is initialised, an obstacle can be detected during closing of the window in manual or automatic mode / the Hall effect sensor measures the variation in the speed of rotation of the motor, and sends this data to the ECU
The safety cycle is as follows
- Reversal of the direction of movement of the window
- Lowering of the window by 125 mm or to the lower limit (if reached before 125 mm)
- Stopping of the window
The window must then be closed again by operating (pulling) the control button again; the safety auto-reverse is still active
Safety auto-reverse detection area
The detection of faults varies depending on the point of detection
- Partial opening area (X); no detection
- All of the area (Z) which can be contacted by a 4 mm diameter rod passing between the top of the window and the seal is protected
- Anomalies are detected throughout the whole of the area (A)
- The area (Y) located 60 mm above the lower limit has no protection
Инициализация
The safety auto-reverse window mechanism must be initialised each time the permanent +ve 12 V supply is cut off if the window is any position other than at the upper limit
With the door closed and the ignition on, operate the window control until it closes completely and keep operating the control for more than 200 milliseconds to allow the electronics to detect the upper limit (relay clicks), (closing is a step-by-step cycle): when this procedure is completed, the window mechanism ECU stores the upper limit position, and the system is initialised
If this operation is carried out with the door open, the window lowers 20 to 25 mm after reaching the upper limit
Closing the door will trigger closing of the window and storing of the limit

Computerised lower limit
When the window is fully opened in automatic (one-touch control) mode for the first time, the system stores the mechanical limit position
During following operations, the ECU will cut off the supply to the motor before the window reaches this limit, in order to reduce noise and extend the service life of the assembly
The computerised lower limit is approximately 1 mm above the mechanical limit
The protrusion of the window should be less than 3 mm at the Computerised Lower Limit position
The mechanism returns to the mechanical limit once every 200 cycles, in order to update the stored position
Pressing the switch again from the Computerised Lower Limit will lower the window to the mechanical lower limit
Отключение функции защиты от защемления
The safety cycle may be triggered not by an obstacle, but by a point of resistance (sticking of the seals in icy weather, significant wind force)
In this case, operate the control switch to reach the mechanical lower limit
Within two seconds, reverse the direction of control to reach the mechanical upper limit
When the upper limit has been detected by the electronics (relay clicks), the safety auto-reverse device becomes active again, and incorporates in its procedure the point which it stored during manual control
The safety auto-reverse will remain active as long as movement does not become significantly more difficult
Работа в аварийном режиме
The system has a down-graded operation in the following cases
- After cutting off of battery positive, and until initialisation
- Inconsistent status information
- Неисправность, обнаруженная устройством самоконтроля
Operation in lower mode is characterised by
- Automatic opening and closing prevented
- Ручное опускание стекла разрешено
- Manual closing limited to step-by-step operation with movement of 45 ± 5 mm each time the switch is operated
- Closing in the same conditions when the door is locked using the key, with a pause of 0,5 second(s) between each step
- No partial opening of the window, which means that the door can be opened or closed (with care) when the window is at the upper limit
