Pulse counter with manual reset and electric output signal.
有手动复位和电气输出信号的脉冲计数器。
Applying a negative-going trigger pulse simultaneously to RESET and TRIG during the timing interval discharges C and reinitiates the cycle, commencing on the positive edge of the reset pulse.
应用一个负的触发器脉冲在一个定时周期内来同时复位和触发，这样使电容器C放电并且重新初始化一个循环，从复位脉冲的正边开始启动。
The output is held low as long as the reset pulse is low. To prevent false triggering, when RESET is not used, it should be connected to VCC.
只要复位脉冲低，输出就低。为防止误触发，当不用“复位“的时候，”复位“端应和Vcc端相连。
The pulse width calculating circuit acquires the width of the reset pulse according to the number of the lightened display units.
脉冲宽度计算电路根据被点亮的显示单元的数量，以获得重置脉冲的脉冲宽度。
The reason is that soonest at the next current zero-crossing the firing pulse of thyristors can be reset.
通常的短路故障电流会大大高于这个倍数，而软启动器的晶闸管本身是没有短路分断能力的。
The reason is that soonest at the next current zero-crossing the firing pulse of thyristors can be reset.
通常的短路故障电流会大大高于这个倍数，而软启动器的晶闸管本身是没有短路分断能力的。
