9905-146 封闭式电气操作区 WOODWARD

【产品详情】

伍德沃德零件 9905-146 系列 2301A 负载分配和速度控制。满载时 CT 输出为 3-7 A，功耗 </= 15 W 标称值，MPU 为 1-30 Vac。

控制单元 9905-146 有正向或反向作用单元，该单元由 <> 个端子组成，具有复位、下降、负载增益、斜坡时间、低怠速、增益、额定速度和低怠速、启动燃油限制和执行器补偿电位器。在启动控制和原动机之前，需要设置所有电位器，转动电位器时要小心，因为电位器扭矩过大会影响性能，控制器上只有一个多圈电位器，即额定速度电位器。

负载增益电位器可以在发动机和控制单元启动后进行调整，如果满载读数为 3 伏或低于与满载成比例的 7%，则与控制一起使用的电流互感器可能与控制所需的尺寸不同。CT（电流互感器）输出在满载时通常为 5-<> A 或 <> A 标称值。

如果您拥有的控制单元是高压型号并且发动机无法启动，则此问题的原因就像连接到以下端子的触点的正源一样;14、17、18 和 19 从 16 号端子而不是 16 号端子获取此错误，以纠正此错误，将这些端子的正源连接到端子 0 而不是端子 16。

【英文介绍】

Woodward Part 9905-146 Series 2301A Load Distribution and speed control. CT output at full load is 3-7 A, power consumption </= 15 W nominal, MPU is 1-30 Vac.

The control unit 9905-146 has a forward or reverse action unit consisting of <> terminals with reset, drop, load gain, ramp time, low idle speed, gain, rated speed and low idle speed, starting fuel limit and actuator compensation potentiometer. Before starting the control and prime mover, all potentiometers need to be set, and be careful when turning the potentiometer, because too much torque will affect the performance of the potentiometer, and there is only one multi-turn potentiometer on the controller, that is, the rated speed potentiometer.

The load gain potentiometer can be adjusted after the engine and control unit are started, and if the full load reading is 3 volts or less than 7% proportional to full load, the current transformer used with the control may be of a different size than the one required for the control. CT (current transformer) output is usually 5-<> A or <> A nominal value at full load.

If the control unit you have is a high voltage model and the engine does not start, the cause of this problem is like the positive source of the contacts connected to the following terminals; 14, 17, 18, and 19 take this error from terminal 16 instead of terminal 16 to correct this error by connecting the positive source of these terminals to terminal 0 instead of terminal 16.
