我单位一台CAT980G型装载机在使用3000h后,频繁发生起动机烧损事故。首先检查了启动继电器,结果工作正常。由于该机电路及传感控制部分(见图1)采用CMS(Caterpillar Moni-toring System)卡特彼勒监控系统,进而怀疑ECM(Electronic Control Module)电路监测、控制单元因误指令造成起动机长期工作而烧损。使用卡特专用检测软件(ET)对该机控制单元、线束、电器元件进行数据读取、检查。
My unit a CAT980G loader 3000h after the frequent occurrence of burned starter accident. First check the start relay, the result is working properly. As the machine circuit and sensing control part (see Figure 1) uses CMS (Caterpillar Moni-toring System) Caterpillar monitoring system, and then suspect ECM (Electronic Control Module) circuit monitoring, control unit caused by long-term starter starter error instructions And burn. The use of Carter-specific detection software (ET) on the machine control unit, wiring harness, electrical components for data read, check.
