Chapter 7: Advice for installation
• Use special care for the
cables entry, in order to avoid
moisture and rain penetrating
inside the box.
• For cable entry inside the
covers of board protection, use the
cable-loops given within (as shown in the
drawing)
• In the hard-wired system use anti-fire shielded cable (2 x 0,75 mm² + 8 x 0,22 mm²)
In the wireless system, connect the support pole to ground and use an additional
shield for the supplying cable 220 V ~ inside the pole, in order to create a double
isolation.
• Before installing the support poles in a definitve way, it is suggested to make a trail installation
in order to find out the best position of alignement for the best effective detection:
1
Position the beams couple in the centre of a free area, respecting the minimum distances
for beams positioning and the installation height
2
Supply the transmitter and the receiver with two batteries and orientate TX and RX one
towards the other
3
Check the signal on TP and adjust it at 7,3 V .
4
Move the two beams towards RIGHT/LEFT within 30 - 50 cm and Up/Downwards
checking the variations of signal of TP and identifying the signal max point.
5
Once identified the best position, fix the brackets.
• During positioning and adjusting of the Receiver, take care not to have big bodies inside the
sensitive zone, which will then be moved when the system is in use, such as lorries or cars;
the adjustment could be highly affected.
The fixing bracket
is pre-arranged
for the
installation
on a steel
pipe, whose
e x t e r n a l
diameter is
40 millimeters
Thanks to the two slides on the sides of
the fixing bracket, it is possible to adjust
the inclination (max 5° upwards
and 5° downwards) in both
transmitter and
receiver.
T w o
notches on
the slides indicate the
max inclination
