绿色LED指示灯：
亮表示继电器吸合。即输出端A与C连通。
有以下几种情况导致LED灯熄灭，继电器的断开，即输出端A 与C断开。
1.输出端R，S，T接线相序错误.
2.发生了过压,欠压,缺相,不平衡.
Green LED indicator lamp
If the lamp in on, it indicates the relay picks up, that is, the output terminals A is connected to C.
If the following conditions appear, the LED lamp will go out and the relay is switched off, that is, terminal A is disconnected from C.
1. The phase sequence of output terminals R, S and T is connected incorrectly;
2. Over-voltage, under-voltage, phase-lacking or imbalance happens.
产品主要用途：
主要适用于中央空调，5匹以上柜机空调,电梯，大型机电产品等。
Main purpose of product:
It is mainly suitable for central air conditioner, air conditioner over 5HP,electric elevator and large-scale mechanical and electric products.
产品特性:
该产品主要是当电网中相序发生错乱,缺相,以及电压高于460VAC,和低于342VAC时,对电器的某些控制线圈进行切断电流,从而达到保护目的.
Characteristics of product
This product can switch off some control coil of the electric appliances in case the phase order is in confuse in the network or phase is lack or the voltage is higher than 460VAC and lower than 342VAC thus to reach the protection purpose.
保护特点：
动态缺相、静态缺相保护：指被保护设备在运行状态或非运行状态时，任意一相发生断相故障。指示灯形式为：黄灯灭。
错相保护：防止T、S、R三相交流电源相序接错的一种保护措施。即时动作。指示灯形式为：黄灯灭。
过压保护：指被保护线路电压高于设定值。指示灯形式为：LED灯灭
欠压保护：指被保护线路电压低于设定值。指示灯形式为：LED灯灭
Characteristics of protection
Dynamic phase-lacking protection and static phase-lacking protection, which starts to work if one phase opens when the protected equipment is in operating course or un-operating state. The yellow indicator lamp goes out。
Error-phase protection: It is a protection method preventing T, S and R three-phase power supply connecting incorrectly. It can work instantly and the yellow indicator lamp goes out.
Over-voltage protection: means the voltage of the protected circuit is higher than the set value; the LED indicator lamp goes out.
Under-voltage protection: means the voltage of the protected circuit is lower than the set value; the LED indicator lamp goes out.
性能特点：
监视器的保护功能能够全性能、全气候长期工作。功耗不大于25W；
本产品通过CE认证
Performance characteri stics:
The monitor can exert its protection function wholly and in any climate for a long time. The power≤25W；
This product has pass CE Certification.
工作特点
T、S、R三相接线正确，监视器黄灯亮，继电器吸合；如果相序接错，监视器黄灯灭。
T、S、R三相或任何一相丢失，监视器黄灯灭，电压正常时恢复，黄灯亮，继电器吸合。
Work characteristics:
If three phases T, S and R are in a correct connection, the yellow indicator lamp is on and the relay picks up; If the phase sequence is connected incorrectly, the yellow indicator lamp goes out
If three phases T,S and R, or any phase loses, the yellow indicator lamp goes out. When the voltage is normal, the yellow lamp is on and the relay picked up.
