Engine Monitoring System

Usage:

3512B ED3

电子控制模块

电子控制模块(ECM)为该发动机提供了一个综合、可编程的发动机监控系统。 ECM 监控指定的发动机操作参数,以检测可能会发生的异常情况。 如果指定的操作参数超出了可接受范围,ECM 会有所动作。 ECM 将会根据该情况的严重程度做出反应。 ECM 可能会启动下列动作:

  • 点亮警告灯或警告报警

  • 发动机减额

  • 发动机保护停机

注: 在一定参数或应用情况下,上述动作可能会不启动。

在大多数应用中,可使用 Cat® 电子技师 (ET) 调节监控系统参数的触发点和延迟时间。 有关编程这些参数的具体信息,请参阅故障诊断与排除, "事件代码"。

发动机仪表板

发动机仪表板通常安装在发电机组上。 发动机仪表板可以安装到远离发动机 7.6 m (25 ft) 的位置。 发动机仪表板包括以下控制装置:

  • 紧急停机按钮

  • 发动机控制开关 (ECS)

  • 当地转速控制(如有配备)

  • 报警喇叭

  • 紧急停机指示灯

  • 电子模块控制面板 (EMCP) 4.4 控制面板

EMCP 4.4 发电机组控制 (GSC) 是发电机组控制系统中的主控制器。 如果 EMCP 4.4 GSC 专门需要应用和安装或故障排除信息,请参阅以下内容:

  • 应用和安装指南, LEBE0007

  • 系统操作、故障诊断与排除、测试和调整, UENR1210

EMCP 4.4 软件支持用户界面,并向面板显示器提供关于发电机、发动机和响应式气体混合 (DGB) 系统状态和运行控制的信息。 从 EMCP 4.4 面板显示器中,可以使用操作和状态概览屏幕查看系统状态信息。 有关导航显示屏以访问系统详细信息的更多信息和说明,请参阅应用和安装指南, LEBE0007。
