    10/12 MN04913001Z-EN Engineering Distinction from other The safety-related part of the CMD contactor monitoring regulations device's control system has EN/ISO 13849-1 approval. The CMD is used for safety-related applications in machine control systems. It has not been assigned to a SIL category as per IEC/EN 61508.
  • Page 14: Average Diagnostic Coverage Dc Avg

    10/12 MN04913001Z-EN Engineering Two CMD relays are required in reversing starter circuits. To attain category 3, faults were excluded by wiring inside a control cabinet. On disconnection via the undervoltage release, a time delay of 100 ms G20 % can occur. An enable circuit must be protected with a max.
