WOODWARD 5439-984 涡轮电子调速器

如果需要，下限可以设置为与额定速度一样高，从而限制过程或计算机速度设置降低速度的能力，可用于在速度参考信号丢失时控制发动机运行。

If desired, the lower limit can be set as high as the rated speed, thus limiting the ability of the process or computer speed settings to reduce speed, and can be used to control engine operation in the event of loss of the speed reference signal.

启动燃料限制设置启动序列期间的最大执行器位置,当速度达到控制设定点时，它会偏置,此功能可用于限制过多的启动烟雾，减少过多燃油的冲洗作用造成的气缸磨损，并有助于缩短启动时间。

Starting Fuel Limit sets the maximum actuator position during the starting sequence, which is biased when the speed reaches the control set point. This feature can be used to limit excessive starting fumes, reduce cylinder wear caused by the flushing action of excess fuel, and help shorten start-up times.

如果需要，可提供外部开关连接来禁用启动燃料限制，以防止反向作用系统在磁性拾取器丢失时恢复到启动燃料位置，该控制装置可最大限度地防止电磁和射频干扰。

If desired, an external switch connection can be provided to disable the start fuel restriction to prevent the reverse acting system from reverting to the start fuel position in the event of loss of the magnetic pickup, and the control provides maximum protection against electromagnetic and radio frequency interference.
