Electronic Control Module (Generator Set) - Replace
注: 可以将旧 ECM 的配置保存在 Cat ET 中。 然后,可以将配置上传到新 ECM。
- 新 ECM 必须在安装后重新编程。 如果所替换的 ECM 是功能性的,则记录以下项目:工时计、所有发动机设定点和所有编程设定的备用输入或输出。 请参阅本文档中的系统操作, "设定点编程"章节。
- 使发动机停机。 将正极引线从蓄电池上拆下。
- 将线束接头从 ECM 上拆下。 需要使用 4 mm 六角扳手来转动紧固螺钉。
- 拆下将 ECM 紧固到前面板上的六个螺母。 拆下 ECM。
- 将新 ECM 置于前面板中。 安装之前拆下的六个螺母,以便将新 ECM 固定到前面板上。
- 将线束接头重新连接到 ECM,并将正极引线重新连接到蓄电池。
参考: 发电机组接线图测试和调整, "电子控制模块接线图"
- 使用原 ECM 的值,以便重新编程设定点、备用输入/输出和工时计。 参考步骤 1。
