工作模式的特点，任何时刻控制器只能工作在1 种工作模式下

The characteristics of the working mode, the controller can only work in one working mode at any time

功率因数控制模式的特点：本控制器在出厂前已将工作模式调整在功率因数控制模式下，所有参数已按合理的方式预置，用户只要接线正确就能正常工作，无须任何操作。

无功功率控制模式的特点：能精确的控制电容器组的投切无投切震荡，适合所有工作环境特别是负载轻电容容量大的场合。

Features of power factor control mode: The controller has been adjusted to work in power factor control mode before leaving the factory, all parameters have been preset in the most reasonable way, the user can work normally without any operation as long as the wiring is correct.

Features of reactive power control mode: It can precisely control the capacitor bank without throwing oscillation, which is suitable for all working environment, especially for the occasion of light load and large capacitor capacity.

功率因数控制模式与无功功率控制模式的选择

Selec tion of power factor control mode and r eactive power control mode

控制器工作模式的选择是利用 参数的取值不同来区别的，如用户将参数调节在(1-12) 内则表示控制器工作在功率因数模式下，数据的大小表示控制器输出回路的多少，如用户将参数调节在(50-5000) 则表示控制器工作在无功功率控制模式下，数据的大小表示用户系统总电流互感器变比。

注：在无功功率控制模式下用户在没有使用控制器之前必须给控制器输入实际电流互感器变比及所有电容器容量等参数。

The working mode of the controller is selected by using different values of parameters to distinguish, such as the user will adjust the parameters within (1-12) means that the controller works in the power factor mode, the size of the data indicates how much the controller output loop, such as the user will adjust the parameters in (50-5000) means that the controller works in the reactive power control mode, the size of the data indicates the user's total system current Transformer ratio.

Note: In the reactive power control mode, the user must input the actual current transformer ratio and all capacitor capacity parameters to the controller before using the controller.
