9905-028 控制器 WOODWARD

【产品详情】

伍德沃德 9905-028 2301A 系列负载分配和速度控制。额定用于普通场所，与柴油或汽油发动机一起使用。

伍德沃德 INC 9905A 系列负载分配和速度控制器的 028-2301 型号。该特定型号是正向作用的 20-40 Vdc 型号，控制器也是电流为 0-200 mA 的单独执行器型号。如果在连接模型时，您使用速度调整电位计验证是否使用屏蔽线连接，如果不使用屏蔽线，可能会损坏控制并严重阻碍控制的性能。

在启动之前，原动机评估速度传感器，如果速度传感器出现故障并需要清除，请将控制速度降低 5%。如果由于任何原因需要将外部设备连接到控制器，则用于连接系统和控制器的接线端子位于前面板的下部。

当尝试启动原动机并且它没有启动时，端子 1 和 <> 处可能没有执行器电压，要修复此错误，请在终止原动机电源之前从正确的端子上拔下电线，检查执行器是否未缩短或接地，关闭十八号终端开关，缩短第二十三、二十四号端子;检查端子 <> 到 <> 的电压。评估终端二十八和二十九至少为<> Vrm，并且最低额定速度低于百分之五。

【英文介绍】

Woodward 9905-028 2301A Series Load Distribution and speed control. Rated for general use with diesel or gasoline engines.

Model 028-2301 of Woodward INC 9905A series load distribution and speed controllers. This particular model is a forward-acting 20-40 Vdc model and the controller is also a separate actuator type with a current of 0-200 mA. If you use a speed-adjusted potentiometer to verify that a shielded wire is used when connecting the model, not using a shielded wire can damage the control and seriously hinder the performance of the control.

Before starting, the prime mover evaluates the speed sensor, and if the speed sensor fails and needs to be cleared, reduce the control speed by 5%. If for any reason an external device needs to be connected to the controller, the terminals used to connect the system to the controller are located on the lower part of the front panel.

When you try to start the prime mover and it does not start, there may be no actuator voltage at terminals 1 and <>. To fix this error, unplug the wire from the correct terminal before terminating the prime mover power supply, check whether the actuator is not shortened or grounded, turn off terminal switch No. 18, shorten terminals 23 and 24; Check the voltage from the terminal <> to <>. Evaluate terminals 28 and 29 for at least <> Vrm and have a minimum rated speed of less than five percent.
