Page 3: Introduction
Its non-observance can cause a very serious risk for the exposed personnel. INTRODUCTION The VISION VX 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. -
Page 4: New Safety Parameters For Type 2 Barriers And Mandatory Labelling
NEW SAFETY PARAMETERS FOR TYPE 2 BARRIERS AND MANDATORY LABELLING With the publication of Edition 3 of the harmonized EN 61496-1 standard it is no longer possible to use a Type 2 safety light barrier for safety functions assessed as SIL 2 / PL d. -

– 50 mm and 90 mm (protected height from 300 mm to 1800 mm) PROTECTION OF ARMS AND LEGS VISION VX is available also in the Multibeam and Long Range configuration with the following lens pitch: – 500mm (2 beams), 400mm (3 beams), 300mm (4 beams). -
Page 6: Installation
INSTALLATION Before installing the VISION VX 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. -
Page 7: Position
The recommended Cf factors are shown in the table below: ENVIRONMENTAL CONDITION CORRECTION FACTOR Cf 0.25 Steam 0.50 Dust 0.50 Dense fumes 0.25 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. - Page 8 In addition to the standard VISION models, VISION VX is available in the MASTER/SLAVE configuration. Such configuration is made of two pairs of light curtains, where the two emitters and the two receivers are respectively connected in series. The most common application is shown in Figure 3: the horizontal light curtain (A) has been installed to detect the presence of a person between the vertical light curtain (B) and the dangerous machine at system power-up or restart.

Page 9: Safety Distance Calculation
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 5). According to European standard EN999, the minimum safety distance S must be calculated using the following formula: S = K (t... -

Page 12: Electrical Connections
ELECTRICAL CONNECTIONS WARNINGS Before making the electrical connections, make sure that the supply voltage complies with that specified in the technical data sheet. Emitter and Receiver units must be supplied with 24Vdc±20% power. The external power supply must comply with the standard EN 60204-1. The electrical connections must be made according to the diagrams in this manual. -

Page 20: Configuration And Operation Modes
CONFIGURATION AND OPERATION MODES The VISION VX operation mode is selected realizing appropriate connections on the M12 8 poles of the Receiver (Table 6 and Table 7). AUTOMATIC MODE The VISION VX light curtain does not dispose of a start/restart interlock circuit in automatic mode. -
Page 21: K1/K2 External Contactors Connection
+24VDC MULTIPLE SYSTEMS When more than one VISION VX 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. -
Page 22: Use Of Deflection Mirrors
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. -
Page 23: Distance Between Reflecting Surfaces
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 19, object A is not detected because surface S reflects the beam and closes the optical path between the Emitter and Receiver. -
Page 24: Mechanical Assembly And Optical Alignment
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. -

Page 27: Test Function
TEST FUNCTION The VISION VX barrier system features an automatic self-diagnosis function that enables it to detect response time malfunctions (with a periodic auto-test every 500ms). This safety system is permanently active and does not require any interventions from the outside. -
Page 28: Output Status
OUTPUT STATUS The VISION 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. -
