Tattletale Function

Usage:

769D 5SS
该功能是一个供经理和保养人员使用的辅助工具。 该功能允许对机器历史记录进行追踪。 ECM 会存储重大事件的数据。 可以通过 ET 维修工具和 Caterpillar 监控系统获取这些信息。

记录的事件如下所列。

  • 换档计数器 - 该计数器记录从每个档位换到其他档位的变速箱换档次数。 最多可记录 128 万次。 当变速箱档位开关的位置改变并停留在新位置持续至少 0.5 秒之后,会创建一条新记录。 计数器收集的信息供办公室使用。 可以使用这些信息创建换档方式的历史记录。 也可以使用这些信息来进行比较,以便预测故障之前的修理并设定保养周期表。

  • 锁定离合器计数器 - 该计数器记录换入直接驱动的换档次数。 最多可记录 1200 万次换档。 计数器收集的信息供办公室使用。 也可以使用这些信息来进行比较,以便预测故障之前的修理并设定保养周期表。

  • 空档滑行计数器 - 该计数器记录变速器位于空档位置时机器速度高于 19.3 km/h (12 mph) 的出现次数。

  • 负载计数 - 该计数器记录特定时间段期间运载的负载数。 如果车斗升起 10 秒或以上,就会产生一个计数。

  • 负载总计 - 该计数器记录自从新机或者 ECM 更换之后机器运载的负载总数。 如果车斗升起 10 秒或以上,就会产生一个计数。

  • 变速箱误操作 - 操作员在发动机转速高于 1500 rpm 时从空档换入前进档或者倒档,会发生这种情况。

  • 机器超速 - 操作员在发动机转速处于 2100 rpm(3500 发动机)或者 2475 rpm(3400 发动机)时换入最高档时,会发生这种情况。 如果发动机转速超过 2300 rpm(3500 发动机)或者 2675 rpm(3400 发动机),会记录机器超速事件。

  • QuickEvac- 每次执行快速排放功能时进行一次记录。 当维修软管开关作动泵时,记录该事件。 在每一次 ECM 电源的通电循环中只会记录一次事件。 这将防止为一个 Quick Evac 操作记录多个事件。
