      • 1) In a safe series connection, each downstream safety switch increases the system response time. More response times can be found in the operating instructions.
      • 2) Response time on approach to the enable zone.
      • 3) Detection time for external faults (e.g., short-circuit or cross-circuit of output signal switching devices). Follow the detailed information in the operating instructions.
      • 4) After application of the supply voltage to the safety switch.
