Air Shutoff - Test - Engines that are Equipped with Optional Air Shutoff Systems
进气切断开关可以用于手动启用进气切断系统。 按下该开关会把一个二次脉冲送至进气切断继电器。
进行下述步骤，测试空气切断系统：
- 起动发动机。
- 将变速箱控制置于 空档 (NEUTRAL)位置。
- 推下"空气切断 (AIR SHUTOFF)"开关。
发动机应停机。

必须手动使空气切断阀复位才能进行下一步的发动机操作。 发动机运转过程中"开启/关闭 (OPEN/CLOSED)"必须保持开启。 把指示器从关闭 (CLOSED)位置移到开启 (OPEN)位置。
如果发动机不停机可以使用 卡特彼勒 ET 完成空气切断系统的进一步测试。 有关您发动机的资料，请参阅 故障诊断与排除指南 , "进气切断电路 - 测试"。
