Abstract: A manual override mechanism is presented for a motor driven rotary actuator that allows the output of the actuator to be manually positioned. Once positioned, the output of the actuator may be locked by a locking mechanism to prevent this output from rotating to its quiescent position. When incorporated in a spring return rotary actuator, the manual override may be used to apply a preload on the spring before the driven device is connected. When the actuator is used to drive a valve or damper, the preload applies a positive closing force on the damper in its zero position to ensure a tight closure of the valve or damper. The locking mechanism engages the gear train and opposes the closing force applied by the spring return of the actuator. To disengage the locking mechanism automatically, the motor applies a forward kick to the gear train. Manual disengagement is also provided.
