伍德沃德公司2301A系列的8272-611控制器用作分轴或尾轴控制器。发动机和尾轴的期望转速实际上是相同的，尽管用于识别相同转速的齿轮并不常见。仅使用远程负载的速度存在原动机超速的风险，并可能在启动控制时引起问题。8272-611控制20至160毫安的输出。涡轮机上的燃料控制必须获得该操作信号。

8272-611管理下垂或同步模式的控制。丢弃模式用于两个或多个原动机的并行操作，等时模式用于基本加载。2301A系统的标准硬件是2301A控制器、用于低压型号或高压型号的外部20-40 Vdc电源、90-150 Vdc或88-132 Vac，以及电流和电压互感器(如果搜索型号标识的话);高压型号在前面，低压不在前面。致动器的电压损失将驱动部件达到全燃料，这允许备用部件控制原动机而不是关闭它。

控制装置的安装位置很重要，安装时要考虑维护和修理的空间、足够的通风和保护免受高电流设备的影响。控制和负载共享线总线之间绝对不需要继电器，连接控制线时使用屏蔽电缆。在控制装置完全连接之前，不要给控制装置通电，否则可能会损坏控制装置。

8272-611

The Woodward 2301A series 8272-611 controllers are used as split or tail shaft controllers. The expected speed of the engine and tail shaft is actually the same, although gears used to identify the same speed are not common. There is a risk of over speed of the prime mover when using only remote loads, and it may cause problems when starting control. 8272-611 controls an output of 20 to 160 milliamperes. The fuel control on the turbine must obtain this operation signal.

8272-611 manages the control of droop or synchronization modes. Discard mode is used for parallel operations of two or more prime movers, while isochronous mode is used for basic loading. The standard hardware for the 2301A system is a 2301A controller, an external 20-40 Vdc power supply for low-voltage or high-voltage models, 90-150 Vdc or 88-132 Vac, and current and voltage transformers (if searching for model identification); The high-pressure model is in front, and the low-pressure model is not in front. The voltage loss of the actuator will drive the components to full fuel, allowing the backup components to control the prime mover instead of shutting it down.

The installation position of the control device is very important, and during installation, consideration should be given to maintenance and repair space, sufficient ventilation, and protection from high current equipment. There is absolutely no need for relays between the control and load sharing line buses, and shielded cables are used to connect the control lines. Do not power on the control device until it is fully connected, as it may damage the control device.
