ActiveSafety of machinery—Evaluation of fault masking serial connection of interlocking devices with potential free contacts
机械安全 串联的无电势触点联锁装置故障掩蔽的评价
Application Summary AI generated
This standard specifies methods for evaluating the risk of fault masking when multiple interlocking devices with potential-free contacts are connected in series in safety circuits. It is applied in machinery safety design and testing contexts, particularly for industrial equipment like presses, robots, and automated production lines where reliable interlocking is critical to prevent hazardous machine motion. The standard helps engineers assess whether series connections could hide a single fault, ensuring compliance with functional safety requirements.
