9900-432 控制单元 具有起动电机的原动机中

【产品详情】

伍德沃德 9900-432 系列 2301A 负载分配和速度控制。安装在金属框架中的单个电路板、50/60 Hz 电源和 90-150 VDC。

伍德沃德的 9900-432 控制器是一个前向作用的 110 V 控制单元。2301 A 控制单元由安装在金属板框架中的单个电路板组成;控制设备所需的所有内容都可以通过框架的前部访问。如果在使用此控制时电压损失，执行器将要求执行器使用最少的燃料。控制器的电源需要由 90-150 的 VDC 单元或 88-132 的 VAC 单元或 50/60 Hz 电源提供。

最小燃料接触设计为原动机典型停机的替代方案。在原动机启动之前，控制器的速度信号不存在。在具有起动电机的原动机中，与起动动子相关的速度令人满意，可以提供信号，这意味着启动时不需要超控触点。当不使用最小燃料触点时，低压型号的端子 17 和端子 16 之间必须连接跳线;高压型号的端子 17 和端子 0 之间，如果 24 VDC 未连接到端子 17，则控制将不起作用。

除非使用远程速度微调电位计的替代方法，否则 9900-432 控制器上的外部速度微调必须通过跳线连接到端子 23 和端子 24。控制器的接线必须由带有双绞线配对的屏蔽电缆制成，这些信号线必须屏蔽以避免从附近设备接收其他信号。

【英文介绍】

Woodward 9900-432 Series 2301A Load distribution and speed control. A single circuit board, 50/60 Hz power supply, and 90-150 VDC mounted in a metal frame.

Woodward's 9900-432 controller is a forward-acting 110 V control unit. The 2301A control unit consists of a single circuit board mounted in a metal plate frame; Everything needed to control the device is accessible through the front of the frame. If the voltage is lost while using this control, the actuator will require the actuator to use the least amount of fuel. The power supply for the controller needs to be provided by a 90-150 VDC unit or 88-132 VAC unit or 50/60 Hz power supply.

The minimum fuel contact design is an alternative to the typical shutdown of the prime mover. The speed signal of the controller does not exist until the prime mover starts. In prime movers with a starter motor, the speed associated with the starting actuator is satisfactory enough to provide a signal, which means that no override contact is required for starting. When minimum fuel contacts are not used, jumpers must be connected between terminals 17 and 16 of the low-voltage model. Between terminal 17 and terminal 0 of the high-voltage model, if 24 VDC is not connected to terminal 17, the control will not work.

External speed trimmers on the 9900-432 controller must be connected to terminals 23 and 24 via jumpers unless an alternative method of remote speed trimmer potentiometers is used. The wiring of the controller must be made of shielded cables with twisted pair pairs, and these signal lines must be shielded to avoid receiving other signals from nearby devices.
