  • Page 3: Introduction

    IEC 61496-1,2 and EN 61496-1. VISION MXL is composed of Emitter plus Receiver, with added functions such as Muting, feedback control of eventual external contactors, and manual/automatic function management. A series of warning LEDs located on the Emitter and the Receiver display the information necessary for the correct use of the device and to evaluate eventual functioning anomalies.

  • Page 4: Operation

    40 mm (protected height from 300 mm to 1200 mm) PROTECTION OF HANDS VISION MXL is available also in the 2, 3, 4 beams configuration with the following lens pitch: – 500mm (2 beams), 400mm (3 beams), 300mm (4 beams).

  • Page 5: Installation

    VISION MXL INSTALLATION Before installing the VISION MXL 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 6: Muting Function

    VISION MXL MUTING FUNCTION The Muting function is a temporary suspension of the safety light curtain’s protective function. Carefully check your risk analysis in order to assess whether the Muting function is compatible with your application and what additional measures have to be taken.
  • Page 7 VISION MXL SERIES "MXL T" - KIT OF MXL LIGHT CURTAIN AND SENSOR ELEMENT “MXLT SI” AND “MXLT SE” Integrated Muting sensors – for two-way openings with pallet entrance/exit. In this model, the Muting sensors are the first on one side and the second on the other in relation to the vertical light curtain (Figure 3).

  • Page 9 VISION MXL POSITIONING OF THE MUTING SENSORS The Emitter and Receiver of the light curtain must be positioned so as to permit access to the dangerous area from above, from below and from the sides without first of all intercepting at least one of the optical beams.

  • Page 10: Positioning

    VISION MXL POSITIONING The position of the MXLE Emitter and the MXLR 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 light curtain is shown in the figure below.

  • Page 11: Safety Distance Calculation

    VISION MXL SAFETY DISTANCE CALCULATION The light curtain 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 11).

    VISION MXL VERTICAL POSITION OF THE LIGHT CURTAIN 30 mm and 40 mm resolution models. These models are suitable for the protection of hands. safety light point of The minimum safety distance S is calculated curtain danger according to the following formula:...

  • Page 13: Multiple Systems

    VISION MXL MULTIPLE SYSTEMS When more than one VISION MXL 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 MXL Figure 16 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.

  • Page 15: Mechanical Assembly And Optical Alignment

    VISION MXL 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 16: Electrical Connections

    VISION MXL 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.
