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.

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.

Pu = Pm x Cf

VISION VXL

8540615 • 19/12/2014 • Rev.8 5

The recommended Cf factors are shown in the table below:

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 Smust be calculated

using the following formula:

S = K (t1+ t2) + C

where:

minimum safety distance

approach speed of object to the dangerous area

mm/sec

response time of the safety barrier in seconds

sec

machine response time, in seconds, meaning the time

required for the machine to interrupt the dangerous movement

following transmission of the stop signal

sec

additional distance

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.

VERTICAL POSITION OF THE BARRIER

30 mm and 40 mm resolution models.

These models are suitable for the protection of

hands.

The minimum safety distance Sis calculated

according to the following formula:

S = 2000(t1+ t2) + 8(D-14)

(D=resolution)

This formula is valid for distances Sbetween 100

and 500 mm. If this formula results in Sbeing

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

Hof at least 1800 mm from the base Gof 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 Sis calculated

according to the following formula:

S = 1600 (t1+ t2) + 850

The reccomended height Hfrom the base

(G) must be the following:

HORIZONTAL POSITION OF THE BARRIER

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 Scalculated as follows:

S = 1600(t1+ t2) + 1200 –0.4H
