5SHY3545L0010 可控硅模块

实验方式：即手动操作方式。这种方式是在上位机上对单个设备进行开、关，启、停的操作，设备间的联锁关系已经被解除了，不存在联跳功能，因此这种方式下不能带负载运行。

　　2） 集中联锁手动：此方式是对要启动的流程中的设备按逆煤流方向一对一的启动，按顺煤流方向一对一停机，要求设备启动前须先将三通挡板启动到位，设备的保护动作处理均同自动控制方式。

　　3） 自动方式：按照预先设定的流程启动或停止相关的设备，是一种正常运行方式，要求现场设备必须处于正常状态。自动方式为系统的最佳控制方式，在此方式下，设备的空载运行时间最短，操作员的操作步骤最少。

　　4） 就地方式：在就地操作箱上把手自动选择按钮打在就地位置，从操作箱上发出启停或开关命令，实现对现场设备的操控。在此种方式下，PLC就失去了控制此设备的功能了。
