The document discusses the principles of fail-safe design in control systems, emphasizing the importance of engineering circuits to default to the safest mode
Fail-safe industrial switches
Generally using normally closed (NC) switches in series, fail-safe logic exploits a loss of signal or power to de-energize the actuator, therefore stopping a pump or a valve. NO (Normally Open): NO contacts just when the device is turned on. NC (Normally Closed): Only contacts open. Particularly in safety-critical applications including level control, emergency shutdown, and hazardous process interlocking, fail-safe circuit design is a basic concept in industrial automation and instrumentation systems. Usually to stop or isolate the process, a fail-safe system guarantees that. This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent dama...
