9905-026 反向作用系统 带有单个执行器

【产品详情】

伍德沃德零件 9905-026 2301A 系列负载分配和速度控制。反向作用系统，低压 20-40 VDC，0-200 mA 执行器电流。

这种特定型号是低电压，位于 20-40 Vdc，带有单个执行器。9905-026 型号是反向作用的，执行器电流为 0-200 mA。如果连接不在控制器内部结构中的速度微调或跳线设备，则屏蔽连接到端子 <> 和 <>。

在安装控制器之前，请确保电源已关闭并检查接地;这应通过将端子 11 的电阻取到控制器框架，然后从端子 11 到端子 11 来测量。此控件上的许多设置都是预先设置的，请确保其余和增益电位计都位于中间位置。

对于该模型的操作至关重要的是，安装在设备内的电流互感器可以获取极高的电压，并且在原动机运行时永远不会断开变压器。在安装此控件的过程中，避免使用所有塑料材料、乙烯基和其他任何具有静电的东西非常重要，还要确保避免在电路板周围时在身体上或周围积聚静电。

如果在操作控制时通过控制发生速度信号超控故障，则在原动机和控制启动后，应该只是暂时确定故障速度传感器电路的实现。

【英文介绍】

Woodward Part 9905-026 2301A Series Load distribution and speed control. Reverse acting system, low voltage 20-40 VDC, 0-200 mA actuator current.

This particular model is low voltage, located at 20-40 Vdc, with a single actuator. The 9905-026 model is reverse-acting, with an actuator current of 0-200 mA. Mask connections to terminals <> and <> if connected to speed trimmers or jumper devices that are not in the controller's internal structure.

Before installing the controller, ensure that the power supply is off and the grounding is checked. This should be measured by taking the resistance of terminal 11 to the controller frame and then from terminal 11 to terminal 11. Many of the Settings on this control are pre-set, make sure the rest and the gain potentiometer are in the middle.

Critical to the operation of this model is the fact that the current transformer installed in the device can obtain extremely high voltages and never disconnect the transformer while the prime mover is running. When installing this control, it is important to avoid using all plastic materials, vinyl, and anything else that has static electricity, and to make sure you avoid building up static electricity on or around your body when you are around the board.

If a speed signal override fault occurs through the control while operating the control, the implementation of the faulty speed sensor circuit should only be temporarily determined after the prime mover and control are activated.
