How to connect the three-color warning light of machine tool?

Three-color warning lights generally have five lines. Some tricolor lights have six wires. They are: red, yellow, green, orange, brown and black. Among them, red, yellow and green are light signal lines, orange is buzzer, brown is collinear, and black is power line.

1. First, connect the power cord (black line) of the three-color alarm lamp to the power supply. The power cord is divided into single wire and black-and-white parallel wire, and the single wire is directly connected to the power supply; Double black lines are negative electrodes and white lines are positive electrodes.

2. Tri-color alarm lamp has five signal wires. There are only four tricolor lights, and there is no brown collinear. Among the three colors, red, yellow and green are optical signal lines, corresponding to red light, yellow light and green light respectively; The orange line is an audio line, which is connected with the buzzer; The brown lines are collinear, so it is necessary to connect the signal line and the audio line.

3. After connecting the power supply, it is necessary to judge the sound line. The specific judgment method is: after connecting the power line, turn on the power, and the power indicator light on the adapter will light up. For the 5-wire tricolor lamp, it is necessary to connect the black power cord with the signal lines of red lamp, yellow lamp, green lamp and orange sound line to test the sound of each lamp of tricolor lamp; Six-wire tricolor lamps need to connect the signal lines of red light, yellow light, green light and orange sound line in line to test the sound of each lamp of tricolor lamps.
