当 VisionLink 中的"发动机工作小时"显示的小时数与设备不一致时,即存在工作小时数差异。 使用下面的步骤来纠正这种情况。

在对小时数差异进行故障排除时,请记住以下信息:

  • 如果"主 ECM" 和 PLE601 网络管理器之间的小时数差异大于 50 小时,则通过选择"同步"选项手动进行同步。

  • 打开资产后,资产将需要时间来确保所有 ECM 都通电,并完成同步时钟校验流程。 打开资产后,至少等待五分钟,以便连接 Cat ET。

  • 始终确保所有机器 ECM 都是最新的固件。

  1. 在 VisionLink 中,检查设备是否积累任何小时数和/或记录起动/停止。

    1. 如果小时数增加但总时数不正确,转至步骤 2。

    2. 如果小时数不增加,转至步骤 3。

    注: Cat ET 访问仅在带有标准 9 针维修端口的 Caterpillar 机器上的 PL542 上可用。 将需要使用 140-9442 适配器电缆组件。

  2. 连接到 Cat 电子技师。 导航至 "Service(服务)",并选择 "Synchronize Service Hour Meters(同步工时计)"。

    1. 如果存在非 Product Link 的 "Sync Clock Master(主同步时钟)",则将 Product Link 同步到 "Master(主同步时钟)"。

    2. 如果没有 "Sync Clock Master(主同步时钟)",请手动更正 Product Link 小时数。 如果小时数从机器小时数继续漂移超过百分之一,则转至步骤 4。

  3. 在机器发动机打开的情况下,连接到 Cat ET。 导航到 Product Link ECM 下的 "Service Tool(维修工具)",检查 "Engine Operation Status(发动机操作状态)"是否正确显示 "Running(运转)"。

    1. 如果状态显示 "Running(运转)",确保资产正与后台通信并具有激活的订阅。

    2. 如果状态显示 "Not Running(不运转)",检查 Product Link 设备的所有接线。 如果接线正确,转至步骤 4。

  4. 在发动机运转的情况下,检查蓝色 LED 的状态。

    1. 蓝色 LED 每四秒闪烁一次。 PL542 所需的关键数据不存在, PL542 安装不良,考虑安装 PL241。

    2. 蓝色 LED 每秒闪烁一次,每秒闪烁多次或稳定亮起。 转至步骤 5。

  5. 通过您的代理商 TC 从 Caterpillar 获得更多服务技术支持。 如果要发送服务请求,则 TC 可以通过 PSCRM 系统输入"产品技术"服务请求。
