压力开关(行驶液压系统)
Show/hide table
图 1 | g00932594 |
行驶液压系统的压力开关以信号告知发动机 ECM 充油压力低。
该开关是一个两位式压力开关。 该开关有一套常开触点和常闭触点。电路仅使用常开触点。开关在 1400 kPa (203 psi) 时起作用,在 1100 kPa (160 psi) 时停用。
压力开关(振动液压系统)
Show/hide table
图 2 | g00932594 |
振动液压系统的压力开关以信号告知发动机 ECM 充油压力低。
该开关是一个两位式压力开关。 该开关有一套常开触点和常闭触点。电路仅使用常开触点。开关在 1400 kPa (203 psi) 时起作用,在 1100 kPa (160 psi) 时停用。
温度开关(液压系统)
Show/hide table
图 3 | g00932600 |
液压系统的温度开关以信号告知发动机 ECM 液压油温度高。
该开关是一个两位式温度开关。该开关有一套常开触点和常闭触点。电路仅使用常闭触点。开关在 92° ± 1.5°C (197.6° ± 2.7°F) 时起作用,在 85 °C (185 °F) 时停用。
行动警报器
Show/hide table
图 4 | g00932601 |
行动警报器警告操作员潜在的严重故障。
行动警报器将产生约为 90 dB 的噪音。 当侦测到 3 级警告时,发动机 ECM 启动行动警报器。
指示灯(报警)
