DescriptionGC 308 R
2 Description
The GC 308 R radar sensor has been designed for use as an opening pulse
generator on automatic doors. Due to the Doppler eect, the sensor
detects movements, whereby a distinction is made between approach and
distance to the detector. It is not possible for several sensor systems to inu-
ence each other and result in a hazard.

3 Work to be done before installation
3.1 Installing the drive
XMake sure that the cover of the drive is tted correctly and earthed.
3.2 Positioning the sensor
The GC 308 R is used as an activation sensor for automatic doors.
àThe sensor must be mounted above the door in the case of sliding,
curved sliding, folding and revolving doors. Ideally, the ows of people
walk directly towards the sensor. If the scanning area does not cover the
entire opening width or if ows of people from dierent directions are to
be expected, several GC 308 R can be used.
àIn the case of swing doors the sensor must be mounted on the hinge side
above the swivelling axis.
