EMCP4.2B Caterpillar


Engine Cooldown Warning

Usage:

C3.4B CF6
系统运作描述:

以下情况导致发动机进入停机模式

  • 处于自动模式时,远程启动信号丢失

  • 停止信号输入激活

  • ECMP 的软停机响应

  • 要求发动机停机的数据链路消息

如果发动机正在运行,发动机将继续在冷却状态下运行。 当冷却间隔完成时,发动机将停止。 由于严重故障而立即停机将导致发动机关停,从而旁通冷却定时器。

参考: 有关设置冷却持续时间设定点的更多信息,请参阅测试和调整, "电子控制模块(发电机组)- 配置"。

产生此代码的状况:

当 EMCP 4 确定发动机冷却正在进行时,将会产生发动机冷却代码。 发动机将继续运行,直到冷却持续时间到期。

测试步骤 1. 与操作员交流

注: 不需要进行发动机修理。

  1. 确定导致诊断代码的状况。

预期结果:

由操作员或导致发动机进入冷却模式的软件引发的停机。

结果:

  • 确定 - 停止
