Sample Program 10: Re-trigger and Time Out
Desired Effect: To stop a motor when 10 seconds have elapsed without a
signal from a detector.
Plan: The detector provides a switch closure to Input #3 whenever an object
passes on a conveyer. The signal re-starts Program #7, a 10-second Off
Interval Program, so the conveyer motor on Circuit #2 won't turn off until 10
seconds have passed since the last signal.
