使用说明书Directions for use 

仪器正确连接后，接通电源到额定电压，工作指示灯亮。After the instrument is connected correctly, connect the power supply to the rated voltage, and the working indicator light is on.

将钮子开关打到“试验”位置，“越限”指示灯亮，经数秒延时后“动作”指示灯亮，但继电器不会动作，说明装置内部逻辑功能正常。其延时时间即为为逆功率继电器延时，其值可通过“延时时间”调节电位器进行调整，顺时针为增大方向。然后，将钮子开关打到“运行”位置。Press the button switch to the "test" position, and the "out-of-limit" indicator light is on. After a few seconds of delay, the "action" indicator light is on, but the relay will not move, indicating that the internal logic function of the device is normal. The delay time of the reverse power relay is the delay time of the reverse power relay. Its value can be adjusted by adjusting the potentiometer through the "delay time", and clockwise is the increasing direction. Then, set the button switch to the "run" position.

注意：二次试验的时间间隔应大于30秒。否则，第二次试验的“延时时问”会偏短。Note: The time interval of the second test should be greater than 30 seconds. Otherwise, the "delay time question" of the second trial will be too short.

-P调逆功功率3%～15%（连续可调），S调延时时间3～10S（连续可调）。-P adjusts inverse power 3%～15% (continuously adjustable), and S adjusts delay time 3～10s (continuously adjustable).

机组并联运行时，电压保持额定，让某台机组逆功，达一定值时逆功率“越限”指示灯亮，经延时后“动作”指示灯亮，继电器动作将主开关跳闸，逆功机组介列，动作功率可以通过“动作功率”调节电位器进行调节，顺时针为增大方向。Unit parallel operation, keep the rated voltage, an inverse work units, up to a certain value when the reverse power indicator "the limit", "action" after delay indicator, relay action will be the main switch trip, inverse power unit dielectric column, action power can be adjusted through the "power" to adjust potentiometer, clockwise to increase the direction.

继电器动作将主开关跳闸，逆功机组介列，动作功率可以通过“动作功率”调节电位器进行调节，顺时针为增大方向。Unit parallel operation, keep the rated voltage, an inverse work units, up to a certain value when the reverse power indicator "the limit", "action" after delay indicator, relay action will be the main switch trip, inverse power unit dielectric column, action power can be adjusted through the "power" to adjust potentiometer, clockwise to increase the direction.

如在逆功时继电器不动作，则可能有一相电流互感器的极性接反，应将接到接线端子的3, 4（或5、6)号线对调，对调后如在正功率时继电器动作，应再将电压接线端子的1.2号线对调即可。如在单机运行，正功率时，继电器就动作，则应把电压接线端子1、2号线对调。If the relay does not operate during the reverse power, the polarity of a current transformer may be reversed, so the No. 3, 4 (or 5, 6) line connected to the terminal should be switched. After the switch, if the relay is in operation during the positive power, the No. 1.2 line of the voltage terminal should be switched. If running in a single machine, positive power, the relay will operate, the voltage terminal 1, 2 line should be switched.

额定电压：AC100V-380V-440V，50／60HZ, A、C 二相功耗＜2VA。Rated voltage: AC100V-380V-440V, 50/60Hz, A, C two-phase power consumption < 2VA.

额定电流5A,  A、C 二相、功耗＜1VA。Rated current 5A, A, C two phase, power consumption < 1VA。

 注Note 

接线时要注意电流互感器的同名端，连接要可靠锁紧。When wiring, pay attention to the same name end of the current transformer, and the connection should be reliably locked.

如需方要求供货方整定动作功率和延时时间，可在订货时注明，如不提要求则按动作电流400mA（额定电流的8%)cos Ψ = 0.8延时时间为5秒进行整定出厂。If the buyer requires the supplier to set the operating power and delay time, it can be indicated at the time of ordering. If not, the operating current is 400mA (8% of the rated current) COS Ψ = 0.8, and the delay time is 5 seconds.
