Abstract
A spring cycle tracker system for a door mounted on a track having at least one spring, with the door having an open and closed position. The system has at least one sensed element and a tracker. The tracker has a sensor having at least one sensing element; and a controller having a counter, at least one input signal from the at least one sensing element and at least one output signal. The sensed element and the tracker are mounted such that when the door is moved towards the open position and/or the closed position, the sensed element and the controller are moved adjacent to each other so that the sensing element senses the sensed element, sending an input signal to the controller, incrementing the counter, tracking a number of times the spring is used.
