4常见故障检修流程4.1仪表检测流程仪表的输入、输出屏对维修起到及其重要的作用,所以在维修的时候应先保证仪表能正常工作。仪表4根重要功能线及其状态:C1插头5脚(30#电源输入)为24V,C1插头4脚(LIN线,即通讯线。它和主控板、驱动板的通讯线连接,工作电压在14～16V之间),C1插头7脚(15#电源输入)为24V,C1插头1脚或者3脚(搭铁线)。这4根线中的1根有问题,则仪表不能正常工作。
4 common troubleshooting process 4.1 instrument testing process Instrument input and output screens play an important role in the maintenance, so the maintenance should first ensure that the instrument can work properly. 4 main function of the instrument line and its status: C1 pin 5 feet (30 # power input) is 24V, C1 plug 4 feet (LIN line, that is, communication line. It and the main control board, the drive board communication line connection, the operating voltage Between 14 ~ 16V), C1 pin 7 feet (15 # power input) is 24V, C1 plug 1 foot or 3 feet (ground wire). There is a problem with one of the four wires, so the meter does not work properly.
