Main Functions<\/h2>\n
<\/div>\n
    \n
  1. Dual – Channel Safety Input Monitoring<\/strong>: Monitors 2 – channel safety devices with potential – free outputs, supporting differential time monitoring and cross – circuit detection to ensure the safety of the control loopSICK.<\/li>\n
  2. Reset and EDM Control<\/strong>: Offers manual and automatic reset options via the reset\/EDM input, and enables external device monitoring to enhance the integrity of the safety systemSICK.<\/li>\n
  3. Restart Interlock<\/strong>: Prevents unintended machine restart after a safety stop, reducing the risk of accidents during equipment operationSICK.<\/li>\n
  4. Diagnostic Feedback<\/strong>: Provides 2 application diagnostic outputs and LED indicators for power, safety input status, output status, and fault conditions, facilitating quick troubleshooting and maintenanceSICK.<\/li>\n
  5. Test Pulse Generation<\/strong>: Delivers 3 test pulse outputs with a 40 ms interval and 2 ms width to continuously verify the functionality of connected safety sensorsSICK.<\/li>\n
  6. Stop Category 0 Compliance<\/strong>: Ensures immediate and complete machine shutdown upon detecting a safety hazard, meeting the requirements of IEC 60204 – 1 Stop Category 0SICK.<\/li>\n<\/ol>\n
