Troubleshooting a FisherTek Marble Sorter? - answering machine troubleshooting

I make a marble sorter, first-class engineering and our machine works all right except for one small mistake, it seems that we can not solve. Our program is configured so that a light-break cycle continuously only if a ball on the street. We have the frequency 32, the monitor seems to more or less where the land of light on him. If the light is refracted is that light shines, and if the action amounting to less than 90 clock counterclockwise, then stops and starts the process again when it stopped about 90, then counterclockwise on the right side and finally and run the program again.

Our problem, if ... If we start the engine, the engine runs for about 5 seconds, while the light is switched on without a ball thrown on the street, and then set into motion on their own again without the marble to dictate the direction they are moving to .

We look forward to when this will be answered by Friday. Thank you in advance.
