3 = Connect to the FTC normally closed (NC) terminal on the DUCATI’s
opener electronic board
WARNING: Do not use the 4th down terminal on the photocell RX 7120
Warning: by connecting the photocells, the bridge that keeps closed the
photocell contact must be eliminated.
Photocells are an actve security optional device active during the closing phase of the gate .It prevents that the gate gets in contact with an obstacle that is trapassing the infrared light transmitted from the transmitter
photocell to the receiver photocell.
It is advisable to mount the photocells at a height from the ground between 40 and 100 cm. Photocells can be installed directly on the pillar (without embedding) or on special support columns.
The obstacle is detected only if it is located between the infrared light beam between the two photocells. The device is composed of a transmitter TX and receiver RX. The transmitter TX emits a modulated infrared light
that is detected by the receiver RX, when this beam of light (invisible) is interrupted by the presence of an obstacle, a signal is sent to the electronic board and the doors reverse the direction of travel (this happens only
in the closing phase.) Do not install the photocells at a distance higher than 10m.
Model SW7012 or LASER 7012: pair of niversal photocells u12 / 24V ac / dc
Models SW7120 or LASER 7120: pair of low consumption photocells. Special model recommanded expecially if to be used on of solar powered openers (CTH44 & CTH48 control board)12 / 24V ac / dc
Unscrew the cover of the photocell to fix them to the pillar / column. It is mandatory to perfectly align the photocells.
Attention: photocells model 7012 & 7120 are aestheti-
cally identical.
They shall be identified and distinguished by the label
affixed to the back of the device. Moreover, the model is
also indicated on the printed circuit of the RX photocell
Caution: with CTH44 and CTH48 electronic bo-
ards powered by the solar panel is indispensabie
use of photocells model 7120 in order to contain
the consumption of the system. It is advisable, in
such cases, to install a single pair of photocells.
