Construct a graphical bubbles and arrows representation of the featured state machine. Ref: FSM State Diagrams

Answer

At a minimum, the sketch shall include:

  • 5 named states
  • Outputs associated with each state
  • Transition out of each state (e.g., there are three possible transitions from state closing)
  • Four lines leading to the fault state
  • A reset line leading from fault to opening state
  • All transition lines should identify the contrition associate with the transition.
