Four motors can be started using their respective start buttons $($e$.$g$.,$ Motor $1$ with Start Button $1,$ Motor $2$ with Start Button $2,$ and so on$)$ and can be stopped using their respective stop buttons $($e$.$g$.,$ Motor $1$ with Stop Button $1,$ Motor $2$ with Stop Button $2,$ etc.$).$ However, Motor $1$ cannot be started unless Motor $3$ is running, and Motor $2$ cannot operate unless Motor $4$ is stopped. If a sensor in the system is active, no other motor can be started until Motor $2$ is started first. If any of the overcurrent relays associated with the four motors is triggered, all running motors are stopped. Information regarding the operating motors will be displayed on the interface.
