Specifications for indicator lights
Thread Content
I have a simple question for everyone: How are the colors of electrical device indicator lights specified? Are there standards?
I think the red light indicates operation. . . . The red button represents stop. . . . . I’m looking for a basis
Here, red light means ready; green light means operation in progress. Yellow light indicates a fault. The green button starts the process, while the red button stops it
From what I’ve experienced, it’s like this: the red light means stop (alarm, power supply)； Green light means to proceed ； The white light is the power source ； The yellow light indicates energy storage ； The specific regulations are not clear.
Low-voltage electrical appliance indication: red light for stop, green light for operation, yellow light for fault, white light for power supply indication. High-voltage electrical appliance indication: red light for operation, green light for stop, yellow light for fault, white light for power supply indication.
Not necessarily! There are differences between power plants and chemical industries! For example, power plants use red to indicate startup
Red light for operation, green light for stop, white light for power indicator, yellow light for accident alarm. A red light indicates that the device is in operation, and it also shows the integrity of the tripping circuit ； A green light indicates that the device has stopped, and it also shows the integrity of the closing circuit.
There should be a unified standard; does anyone have it?
Take a look at the colors of the indicator lights and buttons in the GB2682-81 electrical installation kits
Oh, and GBT4025-2003 – Basic and safety rules for human-machine interface symbols; coding rules for indicators and operators
