5)
The sun or brightness sensor enables by means of the “DIP-switch”
No.6
that has to
be in
OFF
position;
6)
The brightness (sun) sensor trips any time that the light intensity value exceeds the
programmed threshold and remains at those values for at least 10 consecutive
minutes. The tripping threshold is adjusted by acting on the
Trimmer RT1 (Fig.3)
placed on the electronic card of the control unit. The trimmer adjusts from
0
(darkness) to about
50 klx
(shining sun and clear midday sky) with intermediate
progressive values; (see diagram given here below). The exceeding of the threshold
set on the trimmer generates an OPEN/CLOSE command to the motors connected
to the outputs
M5
and
M6
(motors
No.3
and
No.4
);
