9905-038  负载分配和速度控制 调整电位器

【产品详情】

伍德沃德零件 9905-039 系列 2301A 负载分配和速度控制。该型号提供减速斜坡，可与柴油发动机一起使用。执行器输出最大 7.5 Vdc，电流为 0 至 214 mA。

9905-039 控制器是反向作用的单个执行器高压型号，电流为 0-200 mA，该型号提供减速斜坡。由于这是一个高压型号，它可以由 88-132 V 交流或 90-150 Vdc 供电。 由于该控制器是高压型号，因此极其重要的是，当控制器连接到的发动机正在运行连接到端子四到九的电线时，不应断开连接，如果出于任何原因发生这种情况，则可能会造成伤害，因为开路会带来以下风险具有极高的电压。

将屏蔽线连接到控制器时，请查看端子并评估它们是否必须打开或关闭才能使控件正常工作，例如，如果使用端子 17、18 和 19，则每个端子都有特定的用途以及是否应该打开或关闭。对于 17 号航站楼，它必须以最低燃料开放;第十八和第十九个终端分别关闭，第十八终端用于覆盖速度信号的丢失，第十九个终端用于额定速度。

在使用控制速度信号丢失时，可能仅在启动故障速度信号时才将执行器电位计定位在启动燃料水平，请注意，由于此控制是反向作用模型，因此不建议不使用启动燃料限制。

【英文介绍】

Woodward Part 9905-039 Series 2301A Load Distribution and speed control. This model offers a deceleration ramp and can be used with a diesel engine. The actuator outputs a maximum of 7.5 Vdc with a current of 0 to 214 mA.

The 9905-039 controller is a reverse-acting single actuator high voltage model with a current of 0-200 mA, which provides a deceleration ramp. Since this is a high-voltage model, it can be powered by 88-132 V AC or 90-150 Vdc. Since this controller is a high voltage model, it is extremely important that the engine to which the controller is connected should not be disconnected while running wires connected to terminals four to nine, and if this happens for any reason it could cause injury as an open circuit carries the risk of having extremely high voltages.

When connecting the shielding wire to the controller, look at the terminals and evaluate whether they must be opened or closed for the control to function properly, for example, if using terminals 17, 18, and 19, each terminal has a specific purpose and whether it should be opened or closed. For Terminal 17, it must be open with minimum fuel; The eighteenth and nineteenth terminals are closed respectively, the eighteenth terminal is used to cover the loss of the speed signal, and the nineteenth terminal is used for the rated speed.

In the event of loss of use of the control speed signal, the actuator potentiometer may be positioned at the start fuel level only when the fault speed signal is activated, note that since this control is a reverse acting model, it is not recommended not to use the start fuel limit.
