      • 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 internal oder external faults (e.g., short-circuit or cross-circuit of output signal switching devices). Follow the detailed information in the operating instructions.
      • 4) The time specified applies to one sensor after the supply voltage has been applied to the safety switch. In a safe series connection, 0.1¬s must be added for each sensor. An additional 0.5¬s per taught-in actuator must be added for uniquely coded and permanently coded sensors.
