What indicates a normal state in industrial equipment?

In the context of industrial equipment, a green indicator light is universally recognized as signaling a normal operating state. This standard color coding stems from general safety practices and protocols in various industries, where green denotes 'go' or that systems are functioning properly without any issues.

When equipment displays a green light, it typically implies that all parameters are within acceptable limits, and the machinery is safe to operate. In many cases, a steady green light can assure operators that no immediate action is required and that the equipment is operating as intended.

The other color indicators, like yellow, blue, or blinking red, often suggest caution, alertness, or malfunction. A yellow light usually indicates a warning or that attention is needed, a blue light may signify a specific condition or status of the machinery that doesn't necessarily mean normal operation, and a blinking red light typically alerts operators to a fault or emergency condition, requiring prompt attention. Understanding these color-coded signals is crucial for maintaining safe and efficient operations in industrial environments.
