Installation
Caution: before proceeding with the installation
of the photocells, verify the compatibility and the
technical features of the control devices to which
will be connected.
Tension selection 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 operation, the
pitches have to be connected through a point of
tinning.
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 obligation to link
in phase, as indicated in the
pictures 1 and 2
. Verify
the presence of the connection
P1
in the photocells
TX, its absence activates the synchronization and
makes it necessary to do the connections 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
. Caution: the synchronization
in DC is not activated, while the presence or the
absences of the connections
P1
in the photocells TX
are irrelevant.
Synchronization of one pair of photocells
The synchronization allows to install two pairs of
photocells very close to each other without problems
of interferences. To activate the synchronization, it
is necessary to remove the connections
P1
inserted
in the photocells TX, connect the current 12/24V AC
50Hz to the terminals 1-2 of the photocells, with
the obligation to do the connection following the
phases as indicated in the
pictures 1 and 2
. If the
connection following the phases has not been done
in the right way, the photocells will not function.
Fixing and setting up the alignment between pairs
of photocells
All the photocells must be installed on solid surfaces
free of vibrations.
The fixed version
M90/F2ES
does not include the
settings for adjusting, so they must be installed only
on linear surfaces and parallel to each other. This
allows a correct centering between the photocells.
The adjustable version
M90/F2ESO
is adjustable
of 210° along the horizontal axis and 15° along the
