Page 2: Introduction
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. -

Page 4: Installation
VISION VXL 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. ... -

Page 6: Safety Distance Calculation
VISION VXL 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). -

Page 9: Electrical Connections
VISION VXL 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 supply that guarantee safe isolation from main voltage. -

+24VDC 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. - Page 14 VISION VXL Systems installed alongside each other: A Installation of two adjacent Emitters Overlapping systems: B L-shaped installation: C Crossed positioning of Emitters and receivers Figure 9 8540615 • 19/12/2014 • Rev.8...

Page 15: Use Of Deflection Mirrors
VISION VXL 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 16: Distance Between Reflecting Surfaces
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. -
Page 17: Mechanical Assembly And Optical Alignment
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. -
