Hello guys, I am currently looking through some examples of how timers work, but this ladder logic diagram gets me really confused.
Once I:1/0 is open and the timer starts timing, the green light should be energized. Once it ends timing, how is it that the red light turns on instead of turn off? I have the simulator, but I still do not understand.
