Signal light flashing
The signal light is for convenient, fast and easy maintenance; the signal is composed of red and orange. The
current state of light flashing depends on the number of pulse flashes.
Signal is as below:
Pause 1 time
RED
Pause twice
Orange
Pause 1 time
(Pause flash: 1-5times) (Pause flash: 1-5times)
