About the 9905-135

AX Controls buys, sells, and repairs Woodward’s 9905-135 control from our latest surplus or restored secondhand inventory. This specific model was designed for Woodward’s 2301A Load Sharing and Speed Control system. When using the actuator output on the control wire it is to terminal nine of the engine governor, to connect the two governors connect the wire from terminal ten of the engine governor to terminal twelve on the tail shaft governor.

Pertaining to the actuator voltage of the control if at the minimal setting slowly begin to turn the rated speed potentiometer clockwise, if using a reverse acting control turn the potentiometer counterclockwise until the voltage just barely begins to steadily climb. If for any reason while operating the prime mover is hunting at a reduced rate begin to increase the reset potentiometer until it begins to stabilize, if this method does not solve the problem and stabilize the prime mover look into assessing the gain potentiometer by slowly decreasing it or decrease the gain potentiometer as well as simultaneously the increasing the actuator compensation. While operating the control the actuator compensation should read at time-continuous compatibility of 0-500 ms.
