Claims
- 1. A method for learning, storing and controlling operational parameters of a door in conjunction with electromechanically influenced operation of an independently operable mechanism connectable with the door and including a piston for controlling door closing characteristics by selected fluid flow within the mechanism, said method comprising the steps of:
- learning operational variables of a particular door installation without user intervention; or activation and
- storing said learned operational variables in memory.
- 2. The method of claim 1 further comprising updating said learned operational variables during operation of the door.
- 3. The method of claim 2 wherein the steps of learning and updating operational variable includes learning and updating friction inherent in operation of the door.
- 4. The method of claim 1 wherein at least one of said unit and the mechanism includes a return spring, the step of learning operational variables including learning preload of said spring.
- 5. The method of claim 1 wherein the step of learning operational variables includes learning the position of said piston when the door is closed.
- 6. The method of claim 1 wherein the step of learning operational variables includes repeating a learn cycle until selected operational variables learned during a cycle match selected stored operational variables learned in a previous cycle.
- 7. The method of claim 6 further comprising initiating a potential mechanical difficulty indication when no said match is found within a preselected number of learn cycles.
- 8. The method of claim 1 wherein the step of continuously learning operational variables of a particular door installation is done by causing a unit to contact and move the piston and thus the door.
