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.
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.
• 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).
m
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 connection cables into the hole on the bottom of
the column.
5.
Connect the photocells and make the necessary adjustments.
6.
Insert the plastic front of the column and slide it down and
then insert the top plug
m
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.
m
WARNING: synchronized operation is possible only
with AC power: 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).
Non-synchronised operation - connect as Fig. 5
(DIP2 set to OFF - DEFAULT)
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.
Synchronised operation - connect as Fig. 4 (DIP2 set to ON)
Supply both pairs of photocells with AC current, inverting the
polarity between the first and second pairs.
DIP-SWITCHES AND JUMPERS (Fig. 3)
The dip-switches and jumpers on the electronic circuits of the
photocells are used to set the operation of the system.
DIP-SWITCH 1 (RX)
ON - normal operation (DEFAULT)
OFF - slower operation (for use when it snows)
m
ATTENTION: slow operation is not compatible with
synchro operation. NEVER set DIP-SWITCH 1 to OFF when
DIP-SWITCH 2 is set to ON
DIP-SWITCH 2 (RX)
OFF - NON synchronized operation (DEFAULT)
ON - synchronized operation
JUMPER J2 (RX)
Position A - relay output with normally closed contact (DEFAULT)
Position B - relay output with normally open contact
NOTE:
for distances less than 2m, remove the
J1
jumper on the
transmitter (TX)
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.
- The receiver LED is on: the photocell is centred, move on to
part 3.
3.
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.)
4.
Then remove the attenuation filter.
5.
Break the infrared beam a number of times: the receiver LED
must switch itself off and the relay must switch.
