Monitoring System

Usage:

3412E 9KS


注意

发动机监测系统不能保证防止突然的事故的发生。 编程设定的延迟和减额程序是设计来最大限度减少错误警报和提供操作人员使发动机停机的时间。


发动机监控系统监测下列参数:

  • 冷却液温度

  • 冷却系统液位(如有配备)

  • 机油压力

  • 机油温度

  • 进气歧管空气温度(如有配备)

  • 燃油压力

  • 燃油温度

发动机监控和系统操作的选项

发动机可以被编程设置为以下模式:

  • 警告

  • 警告/减额

"警告"

"DIAGNOSTIC"(诊断)灯和警告信号(红色灯或蜂鸣器)"接通"并且警告信号持续激活以警告操作员一个或多个发动机参数不在正常操作范围内。

"警告/减额"

"DIAGNOSTIC"(诊断)灯闪烁代码,警告信号(红色灯或蜂鸣器)激活。

当发生下述事件时,减额模式开始起作用并使 "WARNING"(警告)灯闪烁。

  • 机油压力低

  • 冷却液液位低

  • 冷却液温度高

因此,"WARNING"(警告)灯闪烁时,说明 ECM 正在限制发动机功率或将发动机功率减额。 发动机功率减额是用来警告操作员的。 操作员必须采取适当行动以使发动机免遭损坏。

有关更多信息,请参阅故障诊断与排除指南。
