A food processor has the following motor control. It has a switch that is either in the On
position, or Off position. When the motor is stationary and the switch is turned on, then power is applied to a starting coil, and the motor starts. After the motor starts, the power is applied to the running coil, and the motor continues to run. The motor has a heat sensor. If the motor becomes too hot due to overload, then the power to the motor is cut off, and the motor stops.When the motor has cooled down, and it is stationary, power is again applied first to the starting coil, and ten to the running coil, when it is in motion.
Draw the message sequence diagram for the above system (10 Marks)
Draw a use case block diagram, to illustrate the above-described sequence of events
in detail (i.e. the motor was started, run, it overheated, stopped, cooled, and again
started and run) (5 Marks)
