机械设备在各工步的所需的时间基本不变,因此可以用时间为参考,在可编程控制器发出信号,相应的外部执行机构开始动作时起动一个定时器开始定计时,定时器的设定值比正常情况下该动作的持续时间长20%左右。如某执行机构在正常情况下运行10s后,800-372-7402 AVS-1700-ACX使限位开关动作,发出动作结束的信号。在该执行机构开始动作时起动设定值为12s的定时器定时,若12s后还没有收到动作结束的信号,由定时器的常开触点发出故障信号,800-372-7402 AVS-1700-ACX该信号停止正常的程序,起动报警和故障显示程序,使操作人员和维修人员能迅速判别故障的种类,及时采取排除故障的措施。

公司主营进口工控备件,大部分工控备件我们都能帮您从国外调到,由于型号品种繁多,如您需要的型号在本店搜索不到,欢迎随时咨询。

The required time of mechanical equipment in each work step is basically unchanged, so time can be used as a reference. When the programmable controller sends a signal and the corresponding external actuator starts to act, start a timer to start timing. The set value of the timer is about 20% longer than the duration of the b under normal conditions. If an actuator operates for 10s under normal conditions, 800-372-7402 AVS-1700-ACX make the limit switch act and send out the signal of end of b. When the actuator starts to act, start the timer with the set value of 12s. If the signal of b end is not received after 12s, the normally open contact of the timer sends a fault signal, which stops the normal program and starts the alarm and fault display program, so that the operators and maintenance personnel can quickly identify the type of fault and take troubleshooting measures in time.
