WALL INSTALLATION (Fig. 1)
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.
The SHIELD-180 photocells have a horizontal scope of 180° and a
vertical scope of 30°, they can also be applied on uneven surfaces
where the correct alignment between TX and RX is not possible.
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.
m
PLEASE NOTE: position the photocells so as to avoid
that 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.
• Attach the base
A
• Remove the cable gland
D
• Carry out the electrical connections by passing the cable
through the cable gland
E
.
• Place the cable gland

ELECTRICAL CONNECTIONS
m
WARNING: The installation of the unit, safety devices
and accessories must be carried out when the power supply
is disconnected
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.
m
WARNING: the supply of TX and RX must be in phase
(e.g. TX earth with RX earth and 24 V AC TX with 24 V AC
RX).
Synchronised operation - connect as Fig. 4
Supply both pairs of photocells with AC current, inverting the
polarity between the first and second pairs.
Non-synchronised operation - connect as Fig. 5
Supply by direct or alternating current the two pairs of photocells
and install the two pairs in the reverse order with respect to one
another.

Position A - relay output with normally closed contact (DEFAULT)
Position B - relay output with normally open contact
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, slowly
swing the movable part until the receiver LED comes on
- The receiver LED is on: the photocell is centred, move on to
part 3.
m
WARNING: If the receiver LED flashes, the power
supply of TX and RX is out of phase. Check the electrical
connections.
3.
Fix the mobile part of the photocell by tightening the screw
M
4.
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.)
5.
Then remove the attenuation filter.
6.
Break the infrared beam a number of times: the receiver LED
must switch itself off and the relay must switch.
7.
Insert the aluminium cover
F
and tighten the 4 screws
