SAIA PCD1.M2120控制模块怎么使用

行程开关的“预行程”和“过行程”是否合适；行程开关电气功能是否工作正常；否则更换接口板。
9。控制器不通讯确认监视器控制板到主控板的通讯线是否连接无误，确认监视器控制板上的+15V与+5V正确无误；更换主控板。更换监视器。
10。主控板故障监视器与控制器已建立通讯，监视器检测主控板有故障，则报主控板故障。更换监视器。更换主控板。
11。接口板不通讯监视器与接口板未建立通讯，接口板将每5秒钟复位一次监视器，在3分30秒仍未建立通讯，将判断为重故障。通讯线是否正常,检查接线端子是否正确； I/O板工作是否正常.尤其是工作电压； I/O主控板外芯片是否插好。
12。参数错误在修改参数的时候，如果设置的参数有误（同步矢量控制时可能报此故障），则报参数错误故障，请重新修改参数，按复位按钮。
13。外部故障本地高压分断按钮闭合或接口板上高压分断接点闭合时，系统将报外部故障。高压分断按钮是否按下；高压分断端子是否短路；接口板坏；
14。高压失电上级高压电源消失。一般由正常分闸操作引起。若出现异常高压断电情况（无故障记录、无分闸操作），请检查上级开关柜分闸回路。
15。变频器过流变频器输出电流超过变频器额定电流的1.5倍时，变频器将过流保护。输出电压检测板是否正常，有无明显短路、放电痕迹；光纤是否插紧，主回路连接螺钉是否紧固；霍尔元件电源是否正常、霍尔元件输出电流信号是否正确；检查参数设置加速时间是否过短、转矩提升是否过大、启动频率是否过高；电机或负载机械是否堵转，电机绕组和输出电缆绝缘是否损坏；确保所有单元工作正常（拆下单元连接铜排，使用万用表或示波器检测单元输入输出电压和波形是否正常）； with powerful functions, can easily and intuitively carry out upper computer configuration and PLC programming, and supports online download, online modification, offline simulation and debugging and other functions.

5 Conclusion

This paper discusses the design and implementation of sewage treatment plant automatic control system based on LK series PLC, which gives full play to the advantages of LK programmable controller, such as flexible configuration, reliable control, strong openness and convenient on-line maintenance, and provides a reliable guarantee for the safe and stable operation of the whole system. The automatic control system based on LK has been applied in many sewage treatment plants, which has brought considerable economic benefits and good social benefits to enterprises. ACF attaching machine is applicable to ACF pre attaching process in FPC, tab and FOC production process of various LCD panel and sensor glass. Reclaiming and discharging are completed manually, and ACF attaching equipment is completed automatically.
