1.检查继电器的安装是否正确,有无损坏及松动现象。 2.检查继电器的触头动作是否灵活,有无卡碰现象。 3.检查继电器的接线是否正确,接线螺钉是否拧紧。 4.查对电动机的额定电流必须在继电器电流调节凸轮所示电流值范围以内。继电器凸轮上所示最小、中间和最大刻度的刻线是出厂时经试验调整好以后刻上的,如果使用电动机的额定电流不同于这些刻度电流值时,则须按下列步骤对继电器进行动作调整试验:
1. Check the relay installation is correct, there is no damage and loose phenomenon. 2. Check the relay contact action is flexible, with or without touch phenomenon. 3. Check the relay wiring is correct, the wiring screws are tightened. 4. Check the rated current of the motor must be within the range of current values shown by the relay current regulation cam. The minimum, middle and maximum scale marks on the relay cam are inscribed after the factory adjusted by test. If the rated current of the motor is different from the current value of these scale, the following steps must be taken to adjust the relay test:
