Caterpillar 监控系统 通知操作员机器系统的立即发生的故障或机器系统即将发生的故障。 当主显示模块收到故障信号时,警报开始运行。 问题信号反映了机器的异常状况。 当主显示模块探测到控制系统故障时,警报也会开始运行。 机器上的开关、传感器和其他电子控制模块向主显示模块提供信号。 问题信号是下列状况:

  • 一个开关开路。 如果条件超出开关的行程点,开关就会打开。

  • 传感器信息超过极限。 主显示模块决定该极限值。

  • 另一种情况是由另一个电子控制模块探测到异常状况。 然后,异常状况通过 CAT 数据链路与主显示模块进行通信。

主显示模块分析问题信号。 为向操作员通知警报,主显示模块上的显示部件将激活相应的报警指示灯。 下列报警指示将通知操作员:

  • 相应的指示灯每秒大约闪亮9次。

  • 行动灯亮 1 秒,灭 2 秒。

  • 行动警报响 1 秒,停 2 秒。

  • 当最高警报级别为 2-S 时,行动警报持续鸣响。

注: 激活报警指示灯需要一个以上的输入。 主显示模块决定何时激活报警指示灯。

来自机器系统的问题分为三个警告级别。 警告级别基于故障的严重性。 警告级别指示操作员必需的反应。 警报级别 1 代表机器最轻微的问题,警报级别 3 则表示问题最为严重。 根据警报指示器的综合效应,向司机发出不同警报的级别。 请参阅警报操作表格。

注: 请参阅操作和维护手册中有关警报操作的完整信息。
