    Your business issues

    According to your risk assessment, you need to design your machine with a Perimeter Guarding safety function, required to reach PL d EN/ISO 13849-1, SIL 2 EN/IEC 62061, and to meet current safety legislation and standards enabling CE compliance. You also need to expedite the time-consuming offer selection and documentation process. To reduce machine time to market and improve profitability when creating BOM, you need wiring diagrams and reliability calculation of the safety chain.

    Our experts help you throughout the entire machine life cycle.

    • Solutions

      • This Perimeter Guarding with Embedded Safety Module solution provides an efficient way to build machine safety. Modicon TM3 embedded safety module enables the creation of the safety circuit.
      • The documentation provides: wiring diagram, schematic diagram, explanation of application and the safety reliability calculations. The safety chain solution supports the creation of safety architectures with a Category 3 architecture PL d EN/ISO13849-1, and SIL 2 EN/IEC 62061 for the emergency stop function.
      • The safety-related stop function is initiated by actuation of a safety light curtain (ESPE Type 4) designed to protect access into a hazardous zone. Breaks in one or more beams of the light curtain are detected by the processing module, and Safe Stop 1 is initiated on the drive, decelerating movement. After a time delay the safety outputs (stop category 1 EN IEC 60204-1) connected to the safe torque off (STO) input on the drive are deactivated..
    • Value Proposition

      Safety Chain solutions provide a template to solve each safety function around a machine. Using safety chain solutions reduces time to create each safety function to meet the requirements of the machine risk assessment. It is possible to modify the safety chain solutions with products meeting your specific need on the machine and thus can be used as a template when designing the safety functions for your machine and thus improving your efficiency while saving costs in the process. Each safety chain solution contains:

      • Wiring diagram
      • Explanation of the architecture and safety chain
      • Calculation explanation
      • Calculation result
      • TUV Certificate
      • Sistema project file
    • Differentiation

      Safety chain solutions are designed to minimize the complexity of implementing safety on machines. For each safety function around the machine there are ready to use or modify solutions available to customers seeking CE certification.
