VISION VXL
This symbol stands by a very important warning concerning the safety of persons.
Its non-observance can cause a very serious risk for the exposed personnel.
INTRODUCTION
The VISION VXL photoelectric barrier is a multi-beam optoelectronic safety system.
It belongs to the family of Type 2 electrosensitive devices for the protection of personnel
exposed to risks arising from the use of hazardous machinery or plant, according to
standards IEC 61496-1,2 and EN 61496-1.
VISION VXL is a Type 2 photoelectric barrier composed of Emitter and Receiver with
integration of additional functions, such as the external contactors feedback control and the
manual/automatic operation management.
The LEDs present on Emitter and Receiver units labels provides the necessary information
for a correct use of the device and the evaluation of the possible operation defects.
The VISION VXL barrier system features an automatic self-diagnosis function that enables it
to detect every malfunctions (in an maximum execution time of 0,5 sec).
This safety system is permanently active and does not require any interventions from the
outside.
If necessary, for any safety-related problems contact the competent safety
authorities or industrial associations in the country of use.
For applications in the food industry, please contact the manufacturer to ensure that
the barrier contains materials that are compatible with the chemical agents utilized.
The protective function of the optoelectronic devices is not effective in the following cases:
If the machine stopping control cannot be actuated electrically and it is not possible
to stop all dangerous machine movements immediately and at any time during the
operating cycle.
If the machine generates dangerous situations due to material being expelled or
falling from overhead.
Carefully consider the risks analysis of the application and the legislation of the barrier
application Country to establish if the application is compatible with the safety category 2.

P = Pitch between two lenses
D = Diameter of one lens
R = Resolution = P+D
OPERATION
If the protected area is clear, the two outputs on the Receiver are active and enable the
machine to which they are connected to operate normally.
Each time that an object bigger than or equal in size to the resolution of the system
intercepts the optical path of one or more beams, the Receiver deactivates the outputs.
This condition enables hazardous machine movements to be stopped (by means of an
adequate machine emergency stop circuit).
The resolution is the minimum dimensions that an object must have so that, on
crossing the protected area, it will certainly intercept at least one of the optical
beams generated by the barrier (Figure 1).
Figure 1
The resolution is constant irrespectively of work conditions, as it only depends on the
geometric characteristics of the lenses and the distance between the centres of two adjacent
lenses.
The height of the protected area is the height that is actually protected by the safety
barrier. If the latter is placed horizontally, this value refers to the depth of the protected area.
The working range is the maximum operative distance that can exist between the Emitter
and the Receiver.
VISION VXL is available with the following resolutions:
– 30 mm (protected height from 150 mm to 1200 mm)
PROTECTION OF HANDS
– 40 mm (protected height from 300 mm to 1200 mm)
PROTECTION OF HANDS
VISION VXL is available also in the Multibeam configuration with the following lens pitch:
– 500mm (2 beams), 400mm (3 beams), 300mm (4 beams).

INSTALLATION
Before installing the VISION VXL safety system, make sure that:
The safety system is only used as a stopping device and not as a machine control
device.
The machine control can be actuated electrically.
All dangerous machine movements can be interrupted immediately. In particular, the
machine stopping times must be known and, if necessary, measured.
The machine does not generate dangerous situations due to materials projecting or
falling from overhead; if that is not the case, additional mechanical guards must be
installed.
The minimum dimensions of the object that must be intercepted are greater than or
equal to the resolution of the specific model.
Knowledge of the shape and dimensions of the dangerous area enables the width and height
of the relative access area to be calculated.
Compare these dimensions with the maximum working range and the height of the
protected area in relation to the specific model.
The general instructions set out below must be taken into consideration before placing the
safety device in position.
Make sure that the temperature of the environment in which the system is to be
installed is compatible with the temperature parameters contained in the technical
data sheet.
Do not install the Emitter and Receiver close to bright or high-intensity flashing light
sources.
Certain environmental conditions may affect the monitoring capacity of the
photoelectric devices. In order to assure correct operation of equipment in places
that may be subject to fog, rain, smoke or dust, the appropriate correction factors Cf
should be applied to the maximum working range values. In these cases:
where Pu and Pm are, respectively, the working and maximum range in meters.

If the device is installed in places that are subject to sudden changes in temperature,
the appropriate precautions must be taken in order to prevent the formation of
condensation on the lenses, which could have an adverse effect on monitoring.
POSITION
The position of the VXLE Emitter and the VXLR Receiver must prevent access to the danger
zone from above, below and from the sides, unless at least one of the optical beams has
been intercepted. Some useful information regarding the correct position of the barrier is
shown in the figure below.

SAFETY DISTANCE CALCULATION
The barrier must be installed at a distance that is greater than or equal to the minimum
safety distance S, so that a dangerous point can only be reached after all hazardous
machine movements have stopped (Figure 3).
According to European standard EN999, the minimum safety distance S must be calculated
using the following formula:
where:
S = K (t1 + t2) + C
The non-observance of the correct safety distance reduces or cancels the protective
action of the light curtain.
If the position of the barrier does not prevent the operator from having access to the
dangerous area without being detected, additional mechanical guards must be
installed to complete the system.

30 mm and 40 mm resolution models.
These models are suitable for the protection of
hands.
The minimum safety distance S is calculated
according to the following formula:
S = 2000(t1 + t2) + 8(D-14)
(D=resolution)
This formula is valid for distances S between 100
and 500 mm. If this formula results in S being
greater than 500 mm, the distance can be reduced
to a minimum of 500 mm by means of the following
formula:
S = 1600(t1 + t2) + 8(D-14)
If, due to the specific configuration of the machine,
the dangerous area can be accessed from above,
the highest beam of the barrier must be at a height
H of at least 1800 mm from the base G of the
machine.
Figure 4
Multibeam Models.
These models are suitable for the protection of
the entire body and must not be used to protect
arms or legs.
The minimum safety distance S is calculated
according to the following formula:
S = 1600 (t1 + t2) + 850
The reccomended height H from the base
(G) must be the following:

When the object’s direction of approach is parallel to
the floor of the protected area, the barrier must be
installed so that the distance between the outer limit
of the dangerous area and the most external optical
beam is greater than or equal to the minimum safety
distance S calculated as follows:
S = 1600(t1 + t2) + 1200 – 0.4H
where H is the height of the protected surface from
the base of the machine;
H = 15(D-50)
(D=resolution)
In this case, H must always be less than 1 meter.

AUTOMATIC MODE
The VISION VXL light curtain does not dispose of a start/restart interlock circuit in
automatic mode. In most applications this safety function is necessary. Please
consider the risk-analysis of your application about this matter.
In AUTOMATIC functioning, the two static outputs OSSD1 and OSSD2 follow the status of
the guarded opening.
with the area guarded clear, the outputs will supply +24VDC
with the area occupied they will supply 0VDC.

MANUAL MODE
Use of manual mode (start/restart interlock activated) is compulsory if the safety
device controls an opening to protect a danger area and a person, after passing
through the opening, may remain in the danger area without being detected (use as
'trip device' according to IEC 61496). Failure to comply with this rule may result in
very serious hazards for the persons exposed.
In this operating mode the safety outputs OSSD1 and OSSD2 are activated (+24VDC) only if
the protected area is free and after the reception of the RESTART signal, using a push
button or thank to an appropriate control on the SEL_A or SEL_B input (ref. Table 4).
After an interception of the protected area, the safety outputs will be de-activated.
To re-activate them it will be necessary to repeat the sequence described above.
The RESTART command is active with a voltage of +24VDC.
The minimum duration of the RESTART command is 100ms.

K1/K2 EXTERNAL CONTACTORS CONNECTION
In every operating mode the K1/K2 external contactors feedback is activable.
If you want to use this control feature, connect the pin 4 of 8 poles M12 connector with the
power supply (+24VDC) through the series of N.C. contatcts (feedback) of external
contactors.
MULTIPLE SYSTEMS
When more than one VISION VXL system is used, precautions must be taken to avoid
optical interference between them: install units so that the beam emitted by the Emitter of
one system can only be received by the relative Receiver.
Figure 9 illustrates some examples of correct positioning when two photoelectric systems are
installed. Incorrect positioning could generate interference, and may result in malfunctioning.

USE OF DEFLECTION MIRRORS
In order to protect or control areas that can be accessed from more than one side, in addition
to the Emitter and Receiver, one or more deflection mirrors can be installed.
These mirrors enable the optical beams generated by the Emitter to be deviated on one or
more sides.
If the beams emitted by the Emitter must be deviated by 90°, the perpendicular to the
surface of the mirror must form an angle of 45° with the direction of the beams.
The following figure illustrates an application in which two deviation mirrors are used to
provide a U-shaped protection.
Figure 10
The following rules should be taken into consideration when using deviation mirrors:
Place the mirrors so as to ensure compliance with the minimum safety distance
S (Figure 10) on each side from which the danger zone can be accessed.
The working distance (range) is given by the sum of the lengths of all the sides
that give access to the protected area. (Remember that for each mirror used
the maximum working range between the Emitter and the Receiver is
reduced by 15%).
During installation, take great care to avoid twisting along the longitudinal axis
of the mirror.
Make sure, by standing near to and on the axis of the Receiver, that the entire
outline of the Emitter is visible on the first mirror.
The use of more than three deviation mirrors is not recommended.
8540615 • 19/12/2014 • Rev.8 15
Page 16
VISION VXL
DISTANCE BETWEEN REFLECTING SURFACES
The presence of reflecting surfaces in proximity of the photoelectric barrier may generate
spurious reflections that prevent monitoring. With reference to Figure 11, object A is not
detected because surface S reflects the beam and closes the optical path between the
Emitter and Receiver. A minimum distance d must therefore be maintained between any
reflecting surfaces and the protected area. The minimum distance d must be calculated
according to the distance l between the Emitter and the Receiver, considering that the angle
of projection and reception is 5°.
Figure 11
Figure 12 illustrates the values for the minimum distance d that must be maintained when
the distance l between the Emitter and Receiver is changed.
Figure 12
After installing the system, check whether any reflecting surfaces intercept the beams, first in
the centre and then in the vicinity of the Emitter and Receiver. During these operations, the
red LED on the Receiver should never, for any reason switch off.
16 8540615 • 19/12/2014 • Rev.8
Page 17
VISION VXL
MECHANICAL ASSEMBLY AND OPTICAL ALIGNMENT
The Emitter and the Receiver must be assembled opposite each other (at a distance
specified in the technical data sheet). Use the fastening brackets and inserts supplied with
the system to place the Emitter and the Receiver so that these are aligned and parallel to
each other and with the connectors facing the same way.
Depending on the dimensions and the shape of the support on which they are to be installed,
the Emitter and Receiver must be assembled with the fastening inserts at the back, or else
by fitting these in the side groove (Figure 13).
Perfect alignment of the Emitter and Receiver is essential in order to assure correct barrier
operation. The indicator LEDs on the Emitter and Receiver facilitate this operation.
To perform an easier alignment the use of SFB circular brackets is necessary.
These are available on request (ordering code 1330974).
Figure 13
Position the optical axis of the first and last beam of the Emitter on the same
axis as that of the corresponding beams on the Receiver.
Move the Emitter in order to find the area within which the green LED on the
Receiver stays on, then position the first beam of the Emitter (the one close to
the indicator LEDs) in the centre of this area.
Using this beam as a pivot, effect small sideways movements of the opposite
end to move to the protected area clear condition. The green LED on the
Receiver will indicate this condition.
Lock the Emitter and Receiver in place.
If the Emitter and the Receiver are assembled in areas that are subject to strong
vibrations, the use of vibration-damping supports is necessary, in order to
prevent circuit malfunctions (code SAV-3 1200088, code SAV-4 1200089).

TEST FUNCTION
The TEST function is available should the user wish to check equipment connected
downstream of the barrier (without physically entering the protected area).
By means of this function the OSSDs can be switched from ON to OFF as long as the
function remains active. Please see Table 2 (page 10) for details about the use of the test
function. With the test function, which simulates occupation of the protected area, it possible
to verify the operation of the entire system by means of an external supervisor (e.g. PLC,
control module, etc.).
ReeR recommend to operate a TEST function before each work shift to check equipment
connected downstream of the barrier.
The minimum duration of the TEST function must be 40 msec.
PERIODICAL SYSTEM TEST
According the Standard EN 61496-1, a Type 2 photoelectric barrier must carry out a
periodical system test. As decribed above, the VISION VXL barrier features an automatic
self-diagnosis function which is permanently active and verify the entire VXL operation (with
a periodic auto-test every 500ms).
OUTPUT STATUS
The VISION VXL features two static PNP outputs on the Receiver, the status of which
depends on the condition of the protected area.
The maximum load allowed is 500mA at 24VDC, which corresponds to a resistive load of
48. Maxim load capacity corresponds to 2F. The meaning of the status of outputs is
defined in the table below. Any short circuit between outputs or between outputs and 24VDC
or 0VDC power supplies is detected by the barrier.
Table 5
In the protected area clear condition, the Receiver supplies a voltage of 24 VDC on
both outputs. The required load must therefore be connected between the output
terminals and the 0DVC (Figure 15).

The VISION VXL barrier does not require any specific
maintenance operations; however, periodic cleaning of
the front protective surfaces of the Emitter and Receiver
optics is recommended.
Wipe using a clean, damp cloth; in particularly dusty
environments, after cleaning the front surface, the use
of an anti-static spray is recommended.
Never use abrasive or corrosive products, solvents
or alcohol, which could damage parts. Do not use
woollen cloths, that could electrify the front surface.
CHECKOUTS AND MAINTENANCE
VERIFICATION OF BARRIER EFFICIENCY
Before each work shift or just after switching on, check the correct operation of the
photoelectric barrier.
Proceed as follows, intercepting the beams using the appropriate test object (available on
request).
The correct test object must be used for testing, depending on the barrie r resolution.
See page 26 for the correct ordering code.
Refer to Figure 21:
Introduce the test object into the protected area and move it slowly, starting
from the top and moving down (or vice versa), first in the centre and then in the
vicinity of both the Emitter and the Receiver.
Multibeam models:
Intercept each beam with an opaque object, first in the center of the detection
zone and then close to the emitter and the receiver.
Make sure that during each stage of the test object’s movements the red LED
on the Receiver is always on.
Grooving or fine scratching of the front plastic surfaces can increase the amplitude
of the emission angle of the light curtain, jeopardising detection efficiency in the
presence of lateral reflecting surfaces.
It is therefore fundamental to pay particular attention during the cleaning phases of
24 8540615 • 19/12/2014 • Rev.8
the curtain front window, especially in environments where abrasive dusts are
present. (E.g. cement factories, etc).

TROUBLESHOOTING
The indications provided by the LEDs present on the Emitter and Receiver units make it
possible to trace the cause of a system malfunction.
As indicated in the “SIGNALS” chapter of this manual, in the case of a fault, the system is
blocked and the type of fault can be identified by the LEDs present on the Emitter and
Receiver units. (See the tables below).

VISION VXL
In any case, when faced with a system stoppage, switch the system off and then on again, to
exclude any occasional electromagnetic disturbances.
Should the problem persist, contact ReeR’s service department. In case of continued
malfunctioning:
make sure that the Emitter and the Receiver are correctly aligned and that the
front surfaces are perfectly clean.
verify the integrity of electrical connections and check that these have been
made correctly;
check that the supply voltage levels comply with those specified in the
technical data sheet;
the barrier power supply should be kept separate from that of the other electric
power equipment (electric motors, inverters, frequency converters) or other
sources of disturbance.
If it is not possible to clearly identify the malfunction and to remedy it, stop the
machine and contact Reer's Assistance Service.
If correct system operation cannot be restored after carrying out the above procedures, send
the equipment to ReeR’s laboratories, complete with all parts, stating clearly:
the product code number (the P/N field is shown on the product label)
serial number (the S/N field is shown on the product label)
date of purchase;
period of operation;
type of application;
fault.
