Safety systems

The w i n d o w stops (i.e. motor electrical supply is cut off) w h e n the glass reaches the upper or lower end
stop or if an obstacle gets in the w a y and blocks the glass. This is regulated by controlling the self-
adaptive motor direct current.
The electronic control unit behaves as follows:
- If the motor control signal cuts out during operation, the control unit deactivates the system w i t h i n a
maximum time of 5 0 0 milliseconds. This interruption occurs w h e n the controlled current taken up by
the electric w i n d o w motor drops t o less than 0.8 A.
- If the control buttons are faulty (short-circuit or keys stuck d o w n ) , control operation is inhibited at the
time of control unit activation
milliseconds;
- if the buttons are pressed for longer than 12 seconds, motor operation is inhibited; if the descending
key is short-circuited or pressed for longer than 3 0 seconds, the control is inhibited so that the glass
can be closed.
