    In the previous section we configured the timer "T4 1" to time for 20 seconds after the Ball Mill motor starts. If the motor stops for any reason we will need to determine if the motor has run for the 20-second time period. A TON timer is reset when the input logic to the timer is false so if the motor stops I will lose the accumulated time and the "Done" bit if it is has been set.
