4 Installaon
Cauon: before proceeding with the installaon
of the photocells, verify the compability and the
technical features of the control devices to which
will be connected.
Tension selecon of the photocells 12/24V AC/DC
The photocells are adopted to the tension 24V AC/
DC.
For supplying power to the photocells 12V AC/DC,
it is necessary to short circuit the pitches C (see
picture 3) situated on the back of the circuit board
of the photocells. In order to do this operaon, the
pitches have to be connected through a point of
nning.
Power supply of the photocell with 12/24V AC 50Hz
Connect the current 12/24VAC 50Hz to the terminals
1-2 of the photocells without the obligaon to link
in phase, as indicated in the pictures 1 and 2. Verify
the presence of the connecon P1 in the photocells
TX, its absence acvates the synchronizaon and
makes it necessary to do the connecons following
the phases, as indicated in the pictures 1 and 2.
Power supply of the photocell with 12/24V DC
Connect the current 12/24V DC to the terminals of
the photocells, according to the tension polarity, as
indicated in picture 1. Cauon: the synchronizaon
in DC is not acvated, while the presence or the
absences of the connecons P1 in the photocells TX
are irrelevant.
Synchronizaon of one pair of photocells
The synchronizaon allows to install two pairs of
photocells very close to each other without problems
of interferences. To acvate the synchronizaon, it
is necessary to remove the connecons P1 inserted
in the photocells TX, connect the current 12/24V AC
50Hz to the terminals 1-2 of the photocells, with
the obligaon to do the connecon following the
phases as indicated in the pictures 1 and 2. If the
connecon following the phases has not been done
in the right way, the photocells will not funcon.
Control of the correct alignment between the
photocells
The photocell RX has one red led (indicated with L in
the pictures 1 and 2). Its brightness is proporonal
to the power of the received signal and at the same
me, it indicates the correct alignment between
the photocells. Bigger is the brightness, greater it
is the power received and therefore it is beer the
alignment. Even if the photocell RX works also with
low signal received, it is recommend to perform the
best alignment possible, to guarantee an ecient
