48、作，而手动升降正常，这时我们就可以通过观察PLC输入、输出指示灯的办法来排查问题:首先观察相应输入指示灯，若灯亮，则表示从端头站至 PLC的输入回路正常；若指示灯不亮，则需要重点检查输入回路。输入指示灯正常后，察看相应的输出指示灯，若灯亮，则需要重点检查左升电磁阀、24V电源、2Mpa控制油压及其线路连接等；若不亮，则估计PLC自身出现故障。从而根据输入、输出指示灯的状态快速准确地排查问题，处理故障。2.2、内部运行状况指示灯PLC基本单元右方中部有四个指示灯，也就是箭头11 放大图中所示的四个灯，它们表明了PLC 内部的运行状况。这四个指示灯的含义分别是：第一个为 POWER灯，即电源指示灯

49、，正常时，绿色，常亮。第二个为 RUN 灯，即运行指示灯，正常时，绿色，常亮。第三个为BATT.V 灯，即电池电压下降指示灯，正常时熄灭，故障时红色。当此灯红色闪烁时，提示尽快更换电池，当此灯红色常亮时，程序不工作。第四个为PROG-E、CPU-E指示灯，PROG-E 即程序出错指示灯，正常时熄灭，故障时红色闪烁。CPU-E灯，即CPU故障指示灯，正常时熄灭，故障时红色常亮，说明PLC 主模块损坏。注意：对于BATT.V、PROG-E、CPU-E灯，在送、断电的瞬间红色，属正常现象。三）、输入、输出端子文档编码:CZ2W7Q3X7K9 HG9O6R6O4Q6 ZH6F7P1C7H4文档编码:C
