Patent

CA 2034870

The position of the power output member of a motor actuator which is normally controlled by a microprocessor in response to system-supplied condition signals may be set manually by providing a manually controlled selector signal to the microprocessor allowing manually controlled adjustment signals rather than the normal condition signals to form the parameters from which is derived the motor control signal In the preferred embodiment, a first switch generates the selector signal and a second switch generates the adjustment signal. Such apparatus allows a repairer or installer to adjust a mechanical positioning system driven by the motor actuator while the positioning system is in a variety of precisely selected positions. This control system system contains a feature allowing one to change position of the motor actuator's power output member either continuously or incrementally by appropriately manipulating the switch which generates the adjustment signal.
