3.8 Motorized Draft Shield
3.8.1 Sensor Area
The device has a motion sensor that opens the draft shield automatically as soon as
a motion is detected within the sensor area. Following that the draft shield will be
automatically closed again. The operation is optimized for left- and right-handed
users due to the motion sensor.
The motion sensor has a right and a left sensor window.
The motion sensor has two modes:
− Proximity sensor (one-hand operation)
− Crossover method (two-hand operation)
The motion sensor sensitivity can be adjusted in steps (see Chapter “Parameters in
the “Draft Shield” Submenu (Only for Devices with a Motorized Draft Shield)”,
page 46).
3.8.2 Operating Elements for the Draft Shield
The draft shield can be opened and closed via the palm-operated key. Operation via
the palm-operated key enables the opening and closing of the draft shield as well as
the activation and deactivation of the motion sensor.
