这是使用凸轮的鼓轮式顺序控制器控制化工厂药品反应槽的实例。各工序的动作均用由附带的时间继电器进行的时间控制和由水平检测器、计数器、温度计等实现的终端测试点控制。动作顺序如程序表所示,从第一步到第九步按顺序控制各负荷,而第十步到第十二步是快速进给,同时又回到第一步。首先第一步是等待动作指令的工序、按钮信号输入后,便向第二步行进。第二步阀 V_1动作,开始给水。水给到既定水位时,水平检测器 LS_1动作,这一步动作完了,并向第三步行进。第三步是阀 V_1停止工作,传送带用的电动机 M_1起动。然后经过由控制回路的遥控装置 T_1所给定的时间,时间继电器超过给定时间,便向第四道工序行进。以下相同,重复进行。
This is an example of using a cam drum sequencer to control a chemical reaction tank. The operation of each process is controlled by the time controlled by the attached time relay and the terminal test point by the level detector, the counter, the thermometer and the like. Action sequence As shown in the program table, from the first step to the ninth step in order to control the load, and the tenth step to the twelfth step is rapid feed, while back to the first step. First of all, the first step is to wait for the movement instructions. After the button signal is input, the second step will be taken. The second step valve V_1 action, began to feed water. Water to the given water level, the level detector LS_1 action, this step is completed, and to the third step. The third step is to stop the valve V_1, the conveyor belt motor M_1 start. Then after the time given by the remote control T_1 of the control loop, the time relay travels for more than a given time and goes to the fourth sequence. The same below, repeated.
