Monitoring System Parameters

Usage:

3516B 1NW
ECM 提供了一个可编程发动机监测系统。 电子控制模块(ECM)可监测参数。 如果某发动机工作参数超出合格范围,ECM 可启动响应。 ECM 可能会执行三个可能动作:"警告"、"减额"和"停机"。 对于某些参数而言不是所有的反应动作都有效。 Cat® 电子技师(ET)可用来在 ECM 中选择其反应动作。 Cat ET 将编程设定每一个反应动作的监测水平和延迟时间。

注: 当用户要求的任何参数不同于工厂设定值时,这些参数必须通过 Cat ET 进行编程设定。

监测系统参数必须通过 Cat ET 进行编程设定。 为了对监测系统的参数进行编程设定,应从 Cat ET 的菜单内选择 "monitoring(监测)"。 Cat ET 的屏幕提供逐步进行编程设定的引导,以便选择针对选定参数有效的"无动作/警告/减额/停机"选项。 Cat ET 的屏幕也提供改变"警告/减额/停机"设定点的引导。 有些参数需要密码才能进行编程设定。 更多有关监测系统参数的编程设定的信息资料,请参阅 Cat 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 检查参数水平以便确定参数水平是否超过了监测系统的设定点。

任何监测系统的反应动作都将作为事件记录下来。 这些反应动作为"警告"、"减额"或"停机"。 如果参数水平超过了设定点,但反应动作被关掉的话,警告事件仍将被记录下来。

任何传感器故障都将导致监测系统的相应部分无法工作。 ECM 会产生一个针对出故障的传感器的活动诊断编码,但不会记录事件。 有关传感器的更多信息,请参阅故障诊断与排除。
