Abstract:
A method for determining a range of motion of a mechanical device which when operated by an actuator moves between first and second extreme positions of travel, said method comprising:placing the mechanical device into the first extreme position;from the first extreme position, energizing the actuator to move the mechanical device into the second extreme position;starting a timer upon energizing the actuator to move the mechanical device into the second extreme position;terminating the method if the mechanical device fails to reach the second extreme position within a predefined period of time;quantifying an amount of movement which occurs for the mechanical device to reach the second extreme position from the first extreme position by measuring an amount of time which elapses during movement of the mechanical device between the first and second extreme positions and producing a value representing the amount of time; andstoring the value in a memory device.
