Caterpillar监控系统

(1) 行动灯。 (2) 停车制动指示灯。 (3) 制动系统的低油压指示灯。

监控系统提供三个警告级别。 1 级警告只需要操作员注意。 当发生 1 级警告时,监控系统使一个报警指示灯点亮。

2 级警告需要操作员响应。 当发生 2 级警告时,监控系统使一个或更多报警指示器亮起。 2 级警告还可使行动灯 (1) 亮起。

3 级警告要求立即安全关闭机器系统。 当发生 3 级警告时,监控系统使一个或多个报警指示灯点亮。 监控系统还使行动灯 (1) 闪烁。 同时行动警报器也会鸣响。

注: 在排除故障之前不要操作机器。

对于制动系统,当停车制动器处于接合位置而变速箱处于空档位置时,1 级警告发生。 这使停车制动指示灯 (2) 在起动发动机时闪烁。 在将停车制动器移到分离位置后,报警指示灯熄灭。

对于制动系统,当差速器油槽达到 100 °C (212 °F) 的温度时,2 级警告发生。 不过,当油冷却到 95 °C (203 °F) 的最低温度时,警告消失。 此警告不适用于 836K 垃圾填埋压实机。


注意

如果由于任一分动器中的机油超过最高推荐工作温度而发生警告级别 2 ,请立即降档变速箱以降低机器上的负载。 使机油冷却。

如未能冷却轴中机油的温度,可能会导致轴中旋转部件发生严重损坏。


对于制动系统,3 级警告在系统内出现制动器油压损失时出现。 这使得制动系统的低油温指示灯 (3) 发光。 如果停车制动器在机器操作中接合,3 级警告也会出现。

在机器操作过程中出现 3 级警告时,要立即停机并接合停车制动器。 停止发动机。 机器恢复正常工作前应查明警告产生的原因。
