9X-4276 继电器 | |
随动继电器测试将确定内部开关的触点是否在端子（SR-87）和（SR-87a）触点间短路。 随动继电器未通电时，一个触点正常关闭而另一个触点正常打开。 使用 6V-7070 数字万用表 对随动继电器进行测试。
- 从接线箱拆下继电器。 将 24 伏电源的负极导线连接端子（SR-86），正极引线连接端子（SR-30）。
- 将万用表的负极导线置于端子（SR-86）上，万用表的正极引线置于端子（SR-87a）上。 电压应为 24 伏。
- 将万用表的负极导线置于端子（SR-86）上，万用表的正极引线置于端子（SR-87）上。 电压应为零。
- 将跨接线跨接端子 （SR-30） 和 （SR-85）。 将万用表的负极导线置于端子（SR-86）上，万用表的正极引线置于端子（SR-87a）上。 电压应为零。
- 将万用表的负极导线置于端子（SR-87）上，万用表的正极引线置于端子（SR-86）上。 电压应为 24 伏。
- 如果万用表读数有任何错误，则继电器出现故障且需要更换。
