3.0 PRODUCT DESCRIPTION
3.1 Short description
CR0 light curtains are photoelectric devices built according to the IEC 6049 -5-2 norms and they must not be considered as safety
devices. Therefore they must not be used to guarantee operators’ safety nor to protect users on dangerous machines. They must
rather be used to detect objects reducing or obscuring the intensity of light beams that returns from the reflector.
The housing is in aluminium painted in blue RAL5002, size 20x36mm, (20 mm refers to the front side). A groove on the back allo s
connection ith T-shaped components. The top and bottom side are in black PBT, the optical indo is in PMMA. Protection degree
is IP6 .
In all models of the series, CR0 have t o LEDs indicators: Red and Green in combination, indicate the states of the sensor
(alignment, state optics and fault indication), they are arranged at the top of the curtain, the light is intense and diffused in all
directions, this ensures a great visibility in all conditions.
All models in the CR0 have an optic composed of a continuous array of 9x9mm lenses ith a step of 10mm, CR0 have seven
lenses. The optical indo has a height of 69mm; the total height of the curtain is 10 mm.
Emitter and Receiver are alternate ith the follo ing sequence is: E1, R1, E2, R2, E3, R3, E4 ith reference the cable side. This
allo s to realize a continuous succession of six pairs of reflex elements; the emitted light is polarized and has a ave length of
61 nm.
The orking distance is 0.2...5m ith reflector RL106 and lo er ith smaller reflectors, the best detection capability is 6mm.
All models of CR0 series have a teach button (inductive teach could also be available) in the top of the curtain dedicated to the
activation of menu functions: t o levels of Teach-in and Blanking.
The Teach_G (gross teach) select an excess gain equal to 2 times the threshold, the Teach_F (fine teach) select an excess gain
equal to 1.2 times the threshold; the latter should be used only if the system and the environment in hich the product is used are
clean and ith an high mechanical stability.
The sensor does not use automatic systems of signal tracking, but its repeatability is based on a sophisticated control of thermal drift.
The Blanking of the beams, allo s gradually eliminate pairs of beams; the active couples (E+R) may range from a maximum of six to
a minimum of one.
This sensors has a standard output ith M12 male flying connector (240 mm pigtail).
The CR0 models have four interface circuits hich can be combined in different ays depending on the model and the number of
output cables:
a) Supply 15...30V
b) IO_Link output (C/Q), PNP/NPN/PUSH- PULL
c) Auxiliary output (Q): PNP/NPN/PUSH- PULL
d) Auxiliary input, output mode selection LIGHT/DARK (NC/NO) or more.

5.0 START-UP INSTRUCTIONS
5.1 Mechanical mounting of CR models
It is extremely important to fix the sensors and the reflectors to a rigid structure, not subject to deformation or to strong vibrations.
Choose the position of the sensor so as not to expose it to strong sources of natural or artificial light and to light interference ith
other sensors in the visible emission.
Keep in mind that the devices are not suitable for outdoor installation, IP67 despite being declared, it is not guaranteed that the long
exposure to the eather does not cause ater penetration and performance degradation.
Choose the most suitable reflector to the required detection capabilities and sensing range.
Mount the sensor ith the optical axes as much as possible perpendicular to the reflector surface. The mutual distance depends on the
type of reflector and must be included in the field of specification. To secure the sensors to a support, use the corresponding inserts to
be applied in the rear groove and the brackets in the normal provisioning.
If the application is subject to vibrations, hich any ay do not prevent the optical alignment, use damping supports.
Though used polarized light, the light beams can in part be deflected by reflective surfaces parallel and near to the beams, this can
lead to a missed detections of the interruption of direct path of the of the optical beam, or incorrect calibration values that may
generate unstable operation, so all reflective surfaces and reflective objects should maintain a minimum distance from the direct path
of the rays. This distance depend on the aperture angle of optics.
Keep in mind that even if a surface is black, if it is shiny, it can be highly reflective.
If you can’t eliminate or reduce the effect of a reflective surface, it is important that this effect remains stable or that
the system behaves in an acceptable and predictable manner.
Temporarily block the sensor and reflector so that they are aligned and parallel to each other.
5.1 Electrical installation
Use PELV po er supplies, in compliance ith Chap.6.4. of EN 60204-1.
If using a non-stabilized po er supply, the transformer must have double insulation and adequate po er, the secondary inding must
not exceed 18Vac. Use a bridge rectifier, a filtering capacitor ith a minimum value of 1000μF.
Connect the supply cables directly to the source and not do nstream of other po er or highly inductive devices.
Run the cables of the light curtains in dedicated race ays or here only signals run; do not use race ays already carrying po er
cables.
Comply ith the specification of the maximum length of the connection cables. Make sure that the part or parts of the metal structure
on hich the sensors are installed are effectively connected to the same earth ground.
Before inserting the connector, check that the mains voltage and the supply voltage are ithin the required limits, apply the connector
and check again that the supply voltage has a correct nominal value and remains ithin the limits defined in all orking conditions.
Check the limits in the t o extreme conditions of minimum and maximum absorption of all devices connected to the same po er
supply, especially if this is not a stabilized po er supply.
Danger!
In order to carry out the follo ing operations, a voltage supply to the sensor is needed. Before starting this phase,
make sure that the outputs’ s itch cannot lead to any danger.
Make the minimum electrical connections for proper operation, connect the po er cables, connected to the necessary
inputs devices; suitably connected the NC / NO input if it is available, this status is only acquired at po er on.
5.2 Alignment of CR0 models
Applied the supply voltage, the Green LED must be s itched on, if it is off or flashes the supply voltage is not sufficient.
Verify that the emission optics are active and therefore emit a red light, if necessary make a teach-in (even ithout visibility of the
reflector) ith the purpose to activate the alignment function. If possible, observe the reflector from a point near the optical axis and
corrects the alignment so that the light stain completely illuminate the reflector, simultaneously or alternatively use the alignment
function of the Red and Green LED (reduce the red light to a minimum).
Fix the sensor and run no a Teach_F and check the status of the LEDs, if the Red LED is off and the Green on, the alignment as
acceptable and the Teach as successful. If both LEDs are still blinking it means that the alignment is incorrect, so try to get a better
alignment then run a second Teach G or F. After successfully aligned, permanently block the sensor and verify that the sensor detects
properly as expected. If possible, urging the structure, verify that the vibrations do not cause unstable operation.
If the LEDs sho no recognizable behaviors check the error codes in Chapter 5.5
Indication
A correct optical alignment ith a good signal margin prevents unstable functioning of the light curtains, reduces
optical interferences and reflection by shiny surfaces and guarantees better stability in general.
If the range is short, the graininess of the reflector can cause instability, check the behaviour of the system by shifting
the reflector, as an alternative use of reflective paper composed of micro prisms.
Please do not forg
et to reconnect
all
the cables and to control the correct functioning of the application.

10.0 CONTROL OF THE INSTALLED LIGHT CURTAINS
10.1 Purpose of controls.
The controls described here belo are meant to ensure the functional and reliable performances required.
10.2 Preliminary controls before start-up
● All devices must be correctly installed and ell secured.
● The maximum response time must be adequate to the application. Make sure that the sensor’s response time is compatible ith the
specific application, detecting objects of minimum and maximum size, in different positions and, if possible, ith even faster movements
compared to hat the application allo s.
● Make sure that no optically interfering devices are in the visual field of the sensor. Make sure that other devices do not undergo
interferences by the emitted light.
● Make sure that sensors are not exposed to any substance hich might dirty or damage the optics.
● Make sure that technical documentation is available for operators in charge of maintenance.
10.3 Controls device efficiency
● State and efficiency of the device can be checked using a test stick, hich must be detected in a ay that is repetitive in time.
● Make sure that there are no damages nor dirt on optical indo s’ surface. Scratches and tarnished surfaces can negatively affect the
light curtain’s resolution.
● If necessary, clean the optical surface ith a humid antistatic cloth. Do not use any alcohol, nor solvents, nor abrasive substances.
