PCD2.C100

 PCD2.C100初始状态包括：

　　a.供设备用电的电源正常。

　　b.设备选择在自动方式，即PLC控制方式。

　　c.该设备的保护、控制及信号已复位。在确定每台设备均满足初始状态后，由操作员下达起动命令，整个系统从初始状态出发进入起动过程。自检中任一台设备不满足起动的初始条件均不能进行起动操作。在起动过程中各设备状态不断改变，各个单体设备根据工艺流程顺序起动运行，向稳定运行状态前进，最后进入稳定运行状态。稳定运行状态的时间视生产情况确定。当一段生产工作完成后，由操作员操作或由停车条件自动发出停车命令，系统即进入停止过程，待最后一台设备停止完毕后，整个系统又回到了初始状态，等待下一周期。

　　1)在初始阶段，系统各设备自检发生的故障

　　a.供电电源或设备不正常。

　　b.设备控制状态是否选择自动方式。

　　c.未排除故障。

　　2)起动故障常见起动故障为起动超时故障，即PLC驱动输出继电器动作，在正常时间内电动机未能相应起动。

　　3)运行故障在系统运行中，可能出现电动机过载跳闸、自动方式被人为改变、保护人身和设备安全的急停开关动作等突发性事件或故障。以上故障和信号任一种出现，均应将PLC程序立即转入执行停止命令阶段，按程序设定停止生产流程，对于这种需立即中止生产过程的故障，称之为一类故障。Danfoss Temperature Regulator AVTA-20 AVTA20 77-150ºF 100 PSI New
