WOODWARD 5421-112 涡轮电子调速器

WOODWARD模块是一款高性能可编程逻辑控制器，特殊电路提供高低限制调节，这些限制设置了可以通过改变速度设置毫安或电压参考来设置的最大和最小速度。

The WOODWARD module is a high performance programmable logic controller with special circuitry to provide high and low limit adjustments, these limits set the maximum and minimum speeds that can be set by varying the speed setting milliamp or voltage reference.

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.
