How do you program problem 7c? Logic diagram?
5. Draw the relay logic diagram for a circuit that operates as follows:
A. The main switch (MSW) is the emergency stop switch, which is normally closed.
B. When the red pushbutton (PBR) is pressed, the red pilot light and motor one (M1) are energized. They will stay on until MSW is opened.
C. When the green pushbutton (PBG) is closed, both white and green pilot lights turn on, and motor one (M1) and motor two (M2) will run. They will stay on until MSW is opened.
