退浆机流水线已有小部分安全配置（如地垫，安全光幕等），但仍存在如滚筒卷入，围栏防护不足，气泵电机裸露等安全隐患。其中烘房门也存在人进入后打不开的状况。客户已有安全配置将接入我们安全系统进行监控，同时针对客户要求进行整改。

       采用NJ系列PLC分布4个数据控制点，将全线的安全装置统一控制管理，利用触摸屏显示报警点，对全线的安全状况一目了然。 

    Scouring Line has a few safety guard (such as safety mats, safety light curtain, etc.), but there are still risks such as roller involved, less fence protection, bare pump motor. And the chamber door could not open when there is a person inside. The existing safety device will be monitored access our security system, and we will add some new device based on customer requirements.

    The NJ series PLC will be use with 4 control points. All safety devices will be controlled and monitored by it. The HMI will be used for display all of the alarm.
