Monitoring System Parameters
电子控制模块(ECM)可监控发动机工作参数。 如果某发动机工作参数超出合格范围,ECM 可启动响应。 ECM 可能采取的响应有:"警告", 减额 和 "停机"。 不是所有响应对对于所有参数均有效。
某些参数可以进行编程设定。 Caterpillar 电子技师(ET)用于选择 ECM 响应。 Cat ET 用于编程设定可编程参数的监控等级、触发点和延迟时间。
要进行监控系统参数编程设定,在 Cat ET 中的服务菜单中选择"监控"。 Cat ET 屏幕提供可用编程选项的步骤指南。 有些参数需要密码才能进行编程设定。 有关监测系统参数编程设定的更多信息,请参阅 Cat 电子技师(ET)和故障诊断与排除手册。
发动机起动后,发动机监控系统即启用。 当发动机转速超过低于低怠速 50 rpm 的转速点时,ECM 会检查参数等级。 ECM 检查参数等级来确定等级是否超过设定点。
如果超出设定点,仍会记录警告事件。
任何传感器故障都将导致监测系统的相应部分无法工作。 将对故障传感器进行现行诊断。 有关传感器的更多信息,请参阅故障诊断与排除。
