Functional Description ( 97Ti/e and 95Ti/e)
The Smart Stop PCB is designed to sense the presence
of a user on the treadmill deck and pause the treadmill if a
user is not detected. An infrared light is transmitted twice
a second and then is reflected by the user. The light is
then detected by the receiver module. The treadmill
console controls the Enable pulse and reads the output of
the receiver module.
