  • 48. Ball Mill Fan Control

    We want to use the timer logic to satisfy the rest of the second program requirement. The oil pump should stop if the Ball Mill motor stops when it has been running less than 20 seconds, but the fan should run an additional 5 seconds.

    We will take advantage of the properties of a Timer Off instr...

  • 49. Ball Mill Fan and Oil Pump Control

    We will look at the third specification for the program:

    "If the Mill has operated for more than 20 seconds, the fan should remain on until reset by a separate fan reset button, and the oil pump should remain on for an additional 10 seconds after the Mill is turned off."

    We will program the log...

  • 50. Ball Mill Motor Temperature Inter...

    The fourth program requirement requires if the Mill motor temperature goes above 80 degrees C, the mill should be stopped to protect the windings.

    The input from the temperature transmitter will need to be scaled to produce a value in engineering units, in this case, degrees C.

    The “SCALING” in...
