ment" and must respect the local standards and regulations in force.
The use and installation of these appliances must rigorously respect the indications
supplied by the manufacturer and the safety standards and regulations in force.
Attention! Only for EU customers - WEEE marking.
This symbol indicates that once the products life-span has expired
it must be disposed of separately from other rubbish. The user is
therefore obliged to either take the product to a suitable differential
collection site for electronic and electrical goods or to send it back to
the manufacturer if the intention is to replace it with a new equivalent version of
the same product. Suitable differential collection, environmental friendly treatment
and disposal contributes to avoiding negative effects on the ambient and conse-
quently health as well as favouring the recycling of materials. Illicitly disposing of
this product by the owner is punishable by law and will be dealt with according

Description
Modulated infrared barrier consisting of a projector and a receiver. The equipment is
housed in a shockproof and waterproof aluminium casing.
The lenses can be adjusted through 90° horizontally and plus or minus 30° vertically.
These adjustments permit installations where the projector and receiver are at different
heights (see detail A-B, fig. 5). Protection grade IP66.
Use
The infrared barrier constitutes an efficient safety system for the protection of pas-
sageways or spaces which are equipped with automatic door or gate systems
(domestic or industrial).
It is suitable for systems which have a passing room of not more than 60 m. The use
and installation of these devices must respect the safety standards and regulations
in force. The manufacturer accepts no liability for damage caused by, or situations
arising from, the improper use of these appliances.

MODULATED INFRARED BARRIER
SERIAL NUMBER
ZVL448.03
This product has been tried and tested in the manufacturer's laboratory,
during the installation of the product follow the supplied indications carefully.
Installation
In cases where the installation consists of more than one device the following must be
taken into account; two receivers installed on the same side can be operated by one
single projector on the opposite side without compromising the correct functioning of
the system. If this situation occurs unintentionally (i.e. two receivers installed on one
side and a projector, which has to operate only one of the receivers, on the other side)
then care must be taken to maintain the correct distance between the projectors and
the receivers (minimum 600 mm). The projector and receiver are normally positioned
frontally on the same geometrical axis and at the same height from the ground. The
projector and the receiver however can also be installed misaligned and at different
heights (see fig. 5) as the lens with its ball joint always permits perfect centring.
Assembly instructions (see figs 2,3)
• According to the installation requirements work out the point in which the devices
are to be installed and run the cables to those points;
- using the template supplied with the kit mark the points where the wall fastening
holes are to be drilled.
- separate the cover from the base "3";
Passing wiring through the cable clamp "fig. 2a":
- fasten the base "3" to the wall using the screws "4" and the rawlplugs "2";
- fasten the cable clamps "6" to the entry holes "A" in the bases and pass the wiring
through;
- make sure that the type of pipe used allows sufficient grip when it is inserted to
guarantee a protection grade of IP66;
Passing wiring through the wall into the back of the unit "fig. 2b":
- knock out the holes "B" in the bases;
- run the wiring through the holes and apply a gasket;
- wire up the appliance on the terminal board (see fig. 6)
Note: The minimum cable cross section for the connection between the projector
"TX" and the receiver "RX" is 0.2 mm
100m in length;
- Power up the projector and the receiver and carry out the alignment procedure.
- They are correctly aligned when the LED on the projector is "ON" and the LED on
the receiver is "OFF".
- They are incorrectly aligned when both the projector and receiver LEDs are "ON"
(see connection and alignment).
- Check the correct position of the gasket on the cover seat.
- Hook the photoelectric cell cover to the upper part of the base, press downwards
and rotate until the two parts are correctly coupled.
- Fasten down the cover using the two hexagonal screws.
Setting and fine tuning (CDR852A)
The receiver is fitted with a fine tuning trimmer "C" fig. 3.
The appliance is supplied with sensitivity set to minimum.
A reduction in sensitivity is obtained by rotating the trimmer clockwise. An increase
in sensitivity is obtained by rotating the trimmer anticlockwise. Normally an increased
working distance requires greater sensitivity. Bear in mind that at reduced distances
a high sensitivity level will delay the tripping of the relay.
This could mean that a relatively small object travelling rapidly and crossing the beam
may not activate the security relay. Therefore the sensitivity should be adjusted when
centring the photo-electric cells and considering the following:
- the operating distance;
- the relay trip speed;
- the exact centring of the system.
Centring procedure (CDR852A)
1) For perfect centring place the probes over the test point (see fig.3) maintaining the
correct polarity as indicated on the p.c.b. card (lowest setting 2V dc).
2) Set the sensitivity adjustment trimmer to a level which registers minimum voltage
on the tester.
3) Orientate the lens "B" (fig. 3) so as to obtain the maximum signal deviation.
4) Compensate for the excess or lack of sensitivity by adjusting the trimmer "A" fig.
3 until the maximum signal deviation falls between 1 and 1,5V dc.
Centring procedure (CDR842A)
1) Orientate the lens "B" (fig. 3) until the receiver led goes out . The adjustment nuts
are self locking and should neither be loosened nor tightened.
2) For perfect centring place the probes over the test point (see fig. 3) maintaining
the correct polarity as indicated on the p.c.b. card (lowest setting 2V dc) and then
orientate the lens until the maximum signal deviation falls between 0,9 and - 1V dc.
