  • Solutions

    • This solution Guard monitoring with Safety provides an efficient way to build machine safety. The Preventa XPSATE traditional 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 you create 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 designed to protect access into a hazardous zone. Opening the guard is detected by a guard switch monitored by the processing module. Safe Stop 1 is initiated on the drive decelerating movement. After a time delay the delayed 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:
    • Explanation of the architecture and safety chain
    • Wiring diagram
    • Calculation explanation
    • Calculation result
    • TÜV Certificate
    • Sistema project file
  • Differentiation

    Safety chain solutions concept is unique to minimize the complexity for implementing safety on machines. For each safety function around the machine there are ready to use or modify solutions available. Available for customers around the world aiming to reach CE certification.
