我们使用的一台SBR-4型包果收寄机,扳动启动键后,出现过下面一种障碍现象:计算马达常转不停,资费不断进行累加。资费累加的特点是无规律的,角位计数继电器乱跳,角位资费显示往往是二位相邻数字同时出现,关掉停机检修开关,马达虽停止转动,但角位计数继电器仍无规则地乱跳。根据上述障碍现象分析。从计算马达常转不停和角计数继电器乱跳同时出现来看,不会是由于计算电路印刷板原位槽积炭或打印部分发生故障造成的,而可能是交流160伏电源和
We use an SBR-4 baggage receiving and sending machine, pull the start button, there have been one of the obstacles below: The calculation of the motor stop non-stop, continue to accumulate tariffs. Accumulation of charges is characterized by irregular, corner counting relay jerk, corner bit rate display is often two adjacent figures appear at the same time, turn off the shutdown switch, although the motor stops rotating, but the angular position of the relay is still no rules bounce. According to the above analysis of obstacles. From calculating the motor stop and corner counting relay jerk at the same time appear, will not be due to the calculation circuit PCB in-situ slot coke or printed part of the failure caused, and may be AC 160 volts and
