Your business issues

According to your risk assessment, you need to design your machine with a guard monitoring safety function required to achieve PL d EN/ISO 13849-1, SIL 2 EN/IEC 62061, 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 Guard Monitoring with Safety Module solution provides an efficient way to establish machine safety. The Preventa XPSAC traditional safety module enables the creation of the safety circuit.
    • Included documentation provides: Wiring diagram, schematic diagram, explanation of application and safety reliability calculations. The safety chain solution supports creation of safety architectures with a Category 3 architecture PL d EN/ISO13849-1, and SIL 2 EN/IEC 62061 for the guard monitoring function.
    • The safety-related stop function is initiated by actuation of an emergency stop or moveable guard. This is designed to protect access into a hazardous zone. Opening of the guard is detected by guard switches, and is monitored by the processing module. This deactivates the safety module outputs (stop category 0 EN IEC 60204-1) and stops the motor power supply connected to contactors (K1 and K2). The motor will freewheel to a stop.
  • 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, in order to meet the requirements of the machine risk assessment. It is possible to modify the safety chain solution with products suited to the specific needs of the machine, allowing it to be used as a template when designing safety functions, improving efficiency while saving costs. Each safety chain solution contains:

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

    Safety chain solutions are designed to minimize complexity for 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.
