Initial Troubleshooting Procedure

Usage:

322C ADX

电子控制系统

监视器和控制器是电子控制系统的主要部件。 监视器和控制器具有自诊断功能。 监视器将显示向操作员发出的所有激活警告。

您应当确定机器故障是否依旧存在。 您应使用监视器和"维修模式"功能,以确定是否在电子系统中检测到任何系统故障。 如果出现错误代码,则执行以下错误代码程序。 请参阅主题测试和调整, "诊断代码的故障诊断与排除"。 否则,电子控制系统内不太可能存在故障。 对所维修的机器执行运行测试。 执行液压系统维修手册"测试和调整"部分描述的程序。 对运行试验的结果和技术规格进行比较,以确定故障严重性。 执行运行测试时,应当确定液压力是否足够或机具速度是否有问题。 这些故障可影响整个系统或仅影响特定的操作。 如果主泵、先导泵和控制阀的油路出现故障,则会降低机器的整体性能。 控制系统的液压系统的自诊断装置无法检测出此类故障。 要想检测此类故障,需要检查泵的流动特性、主卸压压力、先导压力等。
