Guang Ri elevator has a phase sequence, yellow, green, red and bright. What lights are normal?

1, the elevator phase sequence relay is normally energized (yellow light) and normal (green light).

2. When the phase sequence of the elevator phase sequence relay is wrong, the power supply (yellow light) is normally on, and the normal (green light) is not on.

3. When the elevator phase sequence relay is missing phase, there are two cases of two-phase missing phase. The power supply (yellow light) is not on, and the normal (green light) is not on. Normal (green light) is not lit when one phase is missing, and power supply (yellow light) is always lit when L 1 is missing; When L2 or L3 phase is missing, the power supply (yellow light) is slightly bright.
