(1) 起动马达电磁阀开关(SMMS)。

在配有两台起动马达的系统内采用两个起动马达电磁开关(SMMS)。 每台起动马达采用一个开关。

测试步骤

  1. 从控制面板的下方,断开发电机壳体内端子 TS1-4 和 TS1-5 间的跨接导线。 从控制面板的下方,利用 7X-1710 万用表表笔 测量接头触点 TS1-5 和触点 TS1-2 间的电阻。 电阻测量值应当为以下数值。

    • 单起动马达系统为 26 到 33 欧姆

    • 双起动马达系统为 13 到 17 欧姆

    如果电阻不正常,则更换故障电磁开关。 如果电阻正常,则转至步骤 2。

  1. 断开从小齿轮电磁阀到起动马达的电缆。 在双起动系统的全部两台起动马达上执行此程序。

  1. 连接一块直流电压表。 将正极电缆和负极电缆分别连接到发电机壳体内的端子 TS1-24 和 TS1-25 上。 如果是测试双起动马达系统内的第二个电磁开关,则将负极电缆连接到端子 TS1-26 上。

    注: 步骤 4 的跨接导线只能保持连接 10 秒。

  1. 在发电机壳体内,从 TS1-1 到 TS1-5 临时连接跨接导线。 电压测量后立即断开此导线。 不要让此导线连接的时间超过 10 秒。 正确测量值从大约 24 DCV 变为大约 2 DCV。

如果电压大于 2.0 DCV,则更换电磁开关。 如果开关达到步骤 1 和步骤 4 的要求,则开关功能正常。 重新连接本程序中拆下的导线和电缆。
