- 电压测量
- (A) - (B):24 V
在随后的端子上测量电压。 例如,红色测试针脚 + 连接端子 "A",而黑色测试针脚 - 连接端子 "B"。
- (A) - (B):24 V
- 符号的含义
- 下表描述了特定符号的含义:
- "C-ground":底盘接地端子
- "P-ground":平台接地端子
- "R-ground":继电器面板接地端子
- "Cab-ground":驾驶室接地端子
- "C-ground":底盘接地端子
- 下表描述了特定符号的含义:
- 初步检查
- 接头
执行故障诊断与排除程序前,检查接头的连接情况。 检查接头是否受潮。 接头受潮可产生不良连接。 确保接头正确配合。 确保接头内的针脚牢固。
- 连续
确保以下各项间的连续性:
- "C-ground" - "P-ground"
- "C-ground" - "R-ground"
- "P-ground" - "Cab-ground"
执行连续性检查前,将断路开关转到 OFF 位置。 断电可防止测试仪和电路损坏。
- "C-ground" - "P-ground"
- 接头
- 准备
- 将钥匙起动开关转到关闭位置。
- 液压控制杆处于锁定位置。
- 确保控制器、线束和接头连接完毕。
注: 确保断开的导线没有接触机器,以防止通电时损坏电气部件。
