Cardin Elettronica CDR serie Handbuch Seite 2

Description
Modulated infrared barrier consisting of a transmitter and a receiver.
The equipment is housed in a shockproof and waterproof plastic casing.
The adjustable lens, set on a self lubricating and self locking ball joint, can be ad-
justed through ± 90° horizontally and plus or minus 30° vertically.
The equipment has a double relay with serial exchange and conforms to the safety
directives EN12978 in category 3 of the EN954-1 and category 2 of the EN61496-2.
It is possible to connect up to 3 pairs of photocells and synchronize the transmis-
sion (multiplex system).
Use
The infrared barrier constitutes an efficient safety system for the protection of
passageways or spaces which are equipped with automatic door or gate systems.
The use and installation of these devices must respect the safety standards and
regulations in force.

Transmitter (fig. 2):
- Power supply voltage selection by means of the DIP-SWITCH "D2";
- Green power on led;
- Dip-switch "D2" multiplex installation settings.
Receiver (fig. 1):
- Power supply voltage selection by means of the DIP-SWITCH "D2";
- Green led indicating photoelectric unbroken beam;
- Red led lit continuously: photoelectric beam disturbed or misaligned;
- Red led lit flashing: photoelectric beam not functioning;
- High intensity orange led for centring ;
- Switch "S1" selection between normal operation or centring mode;
- Test point for fine tuning;
- Dip-switch "D1" multiplex installation settings and relay delay mode;
- Jumper "J1" for selecting the output mode (NA/NC – NA/8,2 kΩ).
INSTALLATION
Note: In cases where the installation consists of more than one device you are ad-
vised to use the multiplex function so as to avoid interference between the beams.
In this case each transmitter is associated with a receiver by setting dips 1 and 2
identically (Dip 3 will be ignored).
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 dif-
ferent heights as the lens with its ball joint always permits perfect centring.
Assembly instructions (fig. 3, 4)
• 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. 4":
- 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. 4":
- knock out the holes "B" in the bases;
- run the wiring through the holes and apply a gasket;
MODULATED INFRARED BARRIER
CONNECTIONS AND CENTRING
- Wire up the device according to the indications shown in figures 1 and 2.
- Set DIP-SWITCHES "D2" correctly according to the required voltage.
- Set all "D1" dips to the "off" position both on the receiver as well as on the transmitter.
- Set the switch "S1" to normal operation (NORM).
- Replace the p.c.b. card;
- Once the power has been turned on the following will occur:
- The minimum cable cross section area for the transmitter/receiver is:
Centring should be carried out as follows:
1) Move the switch "S1" on the receiver to the position
2) Orientate the lens until the orange receiver led re-
3) To obtain fine centring use a normal tester
4) Move the switch "S1" on the receiver to the position "NORM" (fig. 1): the green
Receiver settings
- Jumper inserted: setting the output contacts to NO/NC
- Jumper disinserted: setting the output contacts to NA/8,2 kΩ
- DIP 4 in the "Off" position: relay delay of 0,2 seconds
- DIP 4 in the "On" position: relay delay of 3 seconds
Multiplex system
- Position all the transmitters on the same side.
- Connect all the SINC inputs on the receivers in parallel
- Power up the pairs of photoelectric cells and centre
- Carry out the centring procedure separately for each pair
- Power up all the pairs of photoelectric cells and you
Maintenance
• You are advised to check the condition of the relays at the time interval in the
- To calculate the time period we took into account 2000 relay activations per day.
To test the relays proceed as follows:
- switch off the receiver and write down the position of the four dips;
- move the 4 DIPs to OFF;
- move the switch "S1" to the position "REG";
- connect the contacts of a common tester to the outputs COM and NC on the
- power up the receiver and check that the tester indicates open contacts;
- move DIP 1 to ON: the tester must still indicate open contacts;
- move DIP 1 to OFF and DIP 2 to ON: the tester must still indicate open contacts.
If all the steps gave positive results then both relays are deemed to be functioning
correctly.
If this is not the case you will have to replace the receiver immediately. It is forbidden
to use a receiver that has not passed the above mentioned test.
If the test gave you a positive outcome:
- switch off the receiver; disconnect the tester; move the DIPs back to the posi-
the transmitter led will remain permanently lit and, if the receiver is not aligned,
the receiver led will also be lit.
