OCD related to operating the traffic light on the control column
Thread Content
The indicator lights on the operation panel of our equipment turn red when it is in operation and green when it is not. I suffer from OCD, so it makes sense to me that red means stop and green means go; however, some factories use red to indicate stop and green to indicate operation. I would like to ask if there is any particular reason behind this
During operation, both the red and green lights are on; people either turn a blind eye or choose not to look.
I feel the same; every time I see it, I get the urge to turn it green
I still remember during the trial run, the control panel of the device had both red and green lights; from a distance, it was impossible to tell anything from those indicators. Later, it was uniformly changed to red for operation and green for stop; red serves as a warning
Red light indicates danger (in operation), while green light indicates safety (stopped). If it is powered on, the lights will be on; if they are not on, it means no power is supplied, or there may be a fault – the indicator light could be broken
The on-site control panel should indicate a danger signal when the motor is running; therefore, it is more appropriate to use a red indicator light. In the control room, however, the motor is in a normal operating state, so it is more suitable to use a green indicator light.
It seems that the red light is more noticeable than the green light, making it easier to identify. . . At the same time, red represents danger, indicating that it is in operation under voltage. . .
