Better Design Furniture has imported three refurbished medium sized electricity generators. The manager, Sam, was advised that the maximum running time for each generator is eight (8) hours. This is ideal for the company because the plant has to run for a complete twenty four hour period. With three generators running for eight hours each, this equates to twenty four (24) hours. Sam is now in dire need of a circuit that will start-up and shutdown each generator at different eight hour intervals.
According to Sam, the generators should work as follows: • Generator A 12:00 AM - 8:00 AM

• Generator B 8:00 AM - 4:00 PM • Generator C 4:00 PM - 12:00 AM
Sam has recruited your group as interns with the responsibility of designing the system that will execute the above functions. In designing the system, the group should ensure that generators are not allowed to run simultaneously, as this will result in serious damages to Sam’s equipment. In addition, there should be a disable switch which disables the power coming from the generators and enables the use of the Jamaica Public Service’s electric to power the equipment. This is necessary for the technicians to service the generators.
NB: Your counter/counting system should count in minutes and hours that is no need to worry about the seconds.
