Control，即可编程逻辑控制器），是采煤机电气系统的控制中心。采煤机正常工作时,变频器的牵引方向、加减速控制；左右摇臂升降、制动抱闸的开断；左右截割电机的温度监测、牵引变压器温度监测、牵引、截割电机的电流采样；采煤机恒功率保护、“过零保护”、瓦斯断电保护等均通过PLC实现，以达到对采煤机接近完美的控制性能。交流变频电牵引采煤机电控系统选用的PLC是日本三菱公司的Fx2N系列，它具有可靠性高、抗干扰能力强的特点,且采用导轨式安装,非常方便。PLC 采用模块式硬件结构,组合和扩展都相当方便，用程序式的软连接代替传统的继电器式的硬连接，减少了故障连接点，控制系统接线简单、可靠，使得维护检修方便易行。现简要地将其分述如下：一）、结构简介交流变频电牵引采煤机电控系统的PLC由基本单元、扩展模块、特殊模块等组成。PLC实物图如下页所示：文档编码:CZ2W7Q3X7K9 HG9O6R6O4Q6 ZH6F7P1C7H4文档编码:CZ2W7Q3X7K9

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，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:CZ2W7Q3X7K9 HG9O6R6O4Q6
