About the 9905-132
The 9905-132 unit is a 2301A Electronic Load Sharing and Speed control available in low-voltage or high-voltage models manufactured by Woodward. This model was designed as a standard speed control. The two voltage models are typically powered by a power source of 90-150 Vdc or 85-132 Vac for high voltage and 20-40 Vdc for low voltage models depending on the module type the 9905-132 is being used. The power leads are:
- connected from the power source to the control through the fifteenth terminal, negative, and the sixteenth terminal, positive
- connected through corresponding positive and negative leads to the matching terminal on the 9905-132
Power supplies 10-40 Vdc should strictly be dedicated to the governors. The temporary burden terminal block for current transformer correction must be connected by terminals four through nine; if this resister is not used, the engine requires that it is shut down, and the load must also be removed.
9905-132 Standard Speed Control Trim and Sensing
Speed trim is offered on the 9905-132 control depending on the installation, whether it is split shaft or tail shaft; on split shaft installations, the speed trim potentiometer will only need to be turned on the tail shaft governor; the trim may also be installed on the engine governor if wanted and run fully clockwise for standard operation. The 9905-132 unit can be used with a load sensor. When the unit is used with a load sensor, the system shares the collected load with other generators in the system, so long as it is used in parallel with two or more systems. When the 9905-132 is used for its intended purpose, it will maintain and monitor the prime mover's speed to ensure it is used on the set operating level.
