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 consequently 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 to the laws
and standards of the individual member nation.
DESCRIPTION
Modulated infrared barrier consisting of a transmitter and a receiver. The equipment
is housed in a shockproof and waterproof plastic casing. The lenses can be adjusted
through 180° horizontally and plus or minus 30° vertically. These adjustments per-
mit lateral fitting and installations where the transmitter and receiver are at different
heights (see detail e-d, fig.2)
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. It is
suitable for systems which have a passing room of not more than 60m.

INSTALLATION
Note: In cases where the installation consists of more than one device the follow-
ing must be taken into account. Two receivers installed on the same side can be
operated by one single transmitter 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 transmitter, 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 transmitters and the receivers (minimum 600m). The transmitter and
receiver are normally positioned frontally on the same geometrical axis and at the
same height from the ground.
Surface mounted installation CDR851 (fig. 4)
- Installation is possible on all types of structure. Other than the standard aligned
positioning the device can also be positioned both laterally (moving the device out
of the passageway) and at different heights in order to solve problems posed by
different structures ( detail a-b-c-d, fig.2).
- Choose the points at which the devices are to be surface mounted, according to
the requirements of the system.
- Work out the run of the cables from the structure to the point of connection.
- Fix the fast-fitting brackets at the chosen points (detail 1, fig. 4).
- Pass the connecting cables through the hole in the base of the case.
- Move the p.c.b. card slightly then wire up and connect the cables.
- Once the device has been wired up, snap the case to the fast-fitting bracket, re-
membering to place the waterproof seal between the case and the bracket. The joint
between the case and the bracket is guaranteed to be waterproof (detail 2, fig. 4).
- Insert the sealing gasket into its seat on the case, carry out any eventual adjust-
ments and then fit the glass enclosing cover into place (detail 5-6, fig. 4).
- If required fit the optional protective covering which is available on request (detail
7, fig. 4).
Embedded installation CDR851+KIT841VEI (fig. 5)
- Installation is possible on all types of structure.
- Choose the points at which the devices are to be surface mounted, according to
the requirements of the system.
- Excavate the seat for embedding according to the dimensions of the case (detail
1, fig. 5).
- Work out the run of the cables from the structure to the point of connection.
- Pass the cables through the wall and fasten down.
- Pass the connecting cables through the hole in the base of the case.
- Move the p.c.b. card slightly then wire up and connect the cables.
- Once the device has been wired up, insert the base case into the embedding case
and press the two together until the reference pins coincide with the corresponding
holes (detail 1-2, fig.5).
- Insert the sealing gasket into its seat on the case, carry out any eventual adjust-
ments and then fit the glass enclosing cover into place (detail 4-5, fig. 4).
ADJUSTMENT AND FINE TUNING
The appliance is fitted with a trimmer for sensitivity adjustment "A" fig. 6.
Note: The appliance is supplied with the 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.
CONNECTIONS AND CENTRING
- Wire up the device according to the indications shown in fig.3. Remove the p.c.b.
card slightly to facilitate this operation.
- Replace the p.c.b. card.
- Once the power has been turned on the following will occur:
the transmitter led will remain permanently lit and, if the receiver is not aligned,
the receiver led will also be lit.
- The minimum cable cross section area for the transmitter/receiver = 0.2 mm
(AWG #24)
Centring should be carried out as follows
1) Place the probes over the test point (fig. 6) maintaining the correct polarity as
indicated on the p.c.b. card (lowest setting 2 Vdc).
2) Set the sensitivity adjustment trimmer to a level which registers minimum tension
on the tester.
3) Orientate the lens so as to obtain the maximum signal deviation.
4) Compensate for the excess or lack of sensitivity by adjusting the trimmer until the
maximum signal deviation falls between 1 and - 1,5 Vdc.
