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.

Abstract: A door cycle tracker for a door with at least an open position and a closed position mounted on a track having at least one spring. The door cycle tracker includes a counter mounted to the door having an actuator for incrementing the counter; a trip lever pivotally mounted adjacent to the counter and moveable to a position in which the trip lever actuates the counter actuator; and a plate assembly mounted adjacent to the track in a location such that when the door approaches a selected position, the trip lever contacts the plate assembly. When the door slides on the track and the trip lever contacts the plate assembly, the trip lever pivots, contacts the counter actuator and increments the counter.
