开关失灵

所有开关

任何开关失灵都可能是由于下列故障之一造成的:

  • 开关输出断路。

  • 开关输出短接"蓄电池 - 极"或"蓄电池 + 极"。

  • 测得的开关读数超出规格范围。

冷却液温度开关 1

冷却液温度开关监测发动机冷却液温度。 其输出可通过继电器或灯指示冷却液温度过高。 冷却液温度传感器用于确定冷起动条件出现。

冷却液温度开关失灵

诊断灯将会警告操作员冷却液温度传感器的状态。 冷却液温度传感器失灵不会导致发动机停转或任何马力改变。

电子控制调速器 2(如果配备)

如果配备,将由电子控制调速器控制发动机转速。 请参阅专门说明, REHS3720, "Caterpillar 逻辑控制调速器一(LCG1)和 Caterpillar 逻辑控制调速器二(LCG2)"以了解详细信息。

发动机机油压力开关 3

发动机机油压力开关检测发动机机油压力以进行诊断。

机油压力低警告

低压力警告设定点取决于发动机转速。 只有在发动机运转 8 秒钟之后才能检测到并记录故障。

机油压力非常低警告

机油压力非常低设定点取决于发动机转速。

发动机机油压力开关失灵

诊断灯警告用户发动机机油压力开关的状态。 如果发动机机油压力开关失灵,与发动机机油压力相关的策略将被禁用。 发动机机油压力开关失灵将不会导致发动机停转或任何马力改变。
