Assignment
Draw the following diagrams on engineering computation paper and place in your notebook.  Label all devices, take off points and circuit elements following standard conventions.  Drawings should be neat and completed using a straight edge.
  1. Internal "contol" circuit diagram for the reversing magnetic-across-the-line starter
  2. Internal "power" circuit diagram for the reversing magnetic-across-the-line starter
  3. External "control" connection circuit diagram for forward, reverse, and stop control of the reversing magnetic-across-the-line starter
  4. Complete control circuit diagram for forward, reverse, and stop control of the reversing magnetic-across-the-line starter
  5. Complete control circuit diagram for forward, reverse, stop, jog forward and jog reverse control of the reversing magnetic-across-the-line starter (implement using jog circuit #1)
  6. Complete control circuit diagram for forward, reverse, stop, jog forward and jog reverse control of the reversing magnetic-across-the-line starter (implement using jog circuit #2)
  7. Repeat numbers 4,5, and 6 with multiple forward, reverse, stop, jog forward and jog reverse push-buttons.
Explain the term "plugging".
Explain the tem "interlocking"
Explain operational difference between Coil Interlock vs Pushbutton Interlock design.
How does the reversing starter lock out the other direction both mechanically and electrically? 
What does the interlock protect?
