WALL INSTALLATION (Fig. 1 - 3)
For the system to function correctly, it is essential that the
flatness and linearity of the surfaces intended for installation be
checked, then FIX THE PROJECTOR ALONG THE SAME
GEOMETRICAL AXIS AND AT THE SAME HEIGHT ABOVE THE
GROUND, IN FRONT OF THE RECEIVER.
For correct installation, follow the instructions below very
carefully:
• Decide where the photocells are to be installed, taking into
account the need for the photocells to be fixed on a flat,
linear surface.
PLEASE NOTE: position the photocells so as to avoid
the receiver RX facing into the sun.
• Decide where to place the channels for the power supply
cables.
• Open the photocell casing and use the base A to mark out
the positions of the fixing holes.
• Fix the base and connect-up the terminals.
INSTALLATION ON A GARDO PILLAR (Fig. 2)
1. Install the pillars, following the instructions given in the
relevant instruction manual enclosed.
2. Insert the photocell (or photocells, depending on the length of
the strip) into the grooves in the strip.
3. Position the photocell at the desired height and fix it using the
special V screws (Fig.2).
PLEASE NOTE: Current regulations require the recognition
of obstacles with different minimum heights depending on the
type of installation: 30 cm (height recommended for the installation
of the 20 cm photocell) or 70 cm (50 cm recommended height).
Refer to the regulations specific for the type of installation.
4. Insert the connecting cables through the hole located in the
base of the stand.
5. Connect the photocells and align them.
6. Insert the front lens, sliding downwards from above, and
finally insert the upper cap.
PLEASE NOTE: If the signal is not sufficient, check that
the transmitter and receiver are aligned.
Optionally, remove the cover B from the photocell inserted
in the pillar and held in place by the upper cap.
If the photocell is inserted inside the pillar on which there
is an accessory fitted in place of the upper cap, DO NOT
remove the cover.

ELECTRICAL CONNECTIONS

The new range of devices is equipped with a synchronism circuit
allowing the installation of two pairs, even very close together,
without them interfering with one another.
PLEASE NOTE: It is essential that the TX and RX
power supplies be in phase (e.g. TX earth with RX earth
and 24 V AC TX with 24 V AC RX).
Synchronised operation: supply both pairs of photocells with
AC current, inverting the polarity between the first and second
pairs (fig. 4).
Non-synchronised operation: supply both pairs of photocells
with DC current, and install both pairs inversely with respect to
one another (fig.5).
ADJUSTMENT
Having completed the installation, check that the system is
operating correctly:
1. Ensure there are no obstacles between the transmitter and
the receiver.
2. Power-up the system:
- The receiver LED is off: The photocell is not centred;
perform centring, following the instructions given in part 3.
- The receiver LED is on: the photocell is centred, move on to
part 4.
WARNING: If the receiver LED flashes, the power
supply of TX and RX is out of phase.
Check the electrical connections.
3. Adjusting the direction:
To adjust the direction, follow the indications given in figure 1.
Loosen the screws slightly, slowly swing the movable part until
the receiver LED comes on, then tighten up the screws.
4. Insert the gasket D in the base A (Fig.3).
PLEASE NOTE: incorrect insertion of the gasket
seriously compromises the watertight seal of the casing.
5. Place the cover B over the photocell and ensure it is operating
correctly without removing the adhesive attenuation filter C
(the filter simulates adverse weather conditions such as rain,
fog etc.)
6. Then remove the attenuation filter.
7. Break the infrared beam a number of times: the receiver LED
must switch itself off and the relay must switch.
