1. Power on

将控制屏钥匙开关从OFF打向ON位置，观察面板上仪表背景灯亮，表示控制屏已上电，同时机组燃油处于打开状态，电子调速控制器、电喷控制器处于工作状态。

Turn the key switch of the control panel from off to on, and the instrument background light on the observation panel is on, which indicates that the control panel has been powered on, the fuel of the unit is on, and the electronic speed control and EFI controller are in the working state.

2、启动

2. Start

选择机组怠速/全速开关，进行机组启动。通常怠速运行时间不应超过5分钟。

Select the unit idle / full speed switch to start the unit. Generally, the idle running time should not exceed 5 minutes.

按下启动按钮，持续时间不大于30秒，发动机在启动马达带动下开始启动，启动成功，释放启动按钮，机组进入运行状态。

Press the start button, the duration is not more than 30 seconds, the engine starts to start under the drive of the starting motor, the start button is released, and the unit enters into operation state.

一次启动时间应尽量控制在5—10秒，延长启动马达和蓄电池使用寿命。

The starting time should be controlled within 5-10 seconds to prolong the service life of starting motor and battery.

3、运行

3. Operation

机组进入全速运行，发电机电压、频率正常稳定后，操作人员可将发电空开合上。

When the unit is running at full speed and the generator voltage and frequency are normal and stable, the operator can switch on the power generation air switch.

机组在运行中，操作人员还应经常观察了解机组运行是否正常、控制屏仪表指示是否在正常位置、控制 屏有无预报警指示、燃油箱燃油位情况等运行参数，并定时对机组运行参数进行记录。

During the operation of the unit, the operator should often observe and understand whether the unit is running normally, whether the instrument indication of the control panel is in the normal position, whether the control panel has pre alarm indication, fuel tank fuel level and other operating parameters, and regularly record the operation parameters of the unit.

4、急停

4. Emergency stop

一旦操作人员发现机组出现严重故障或配电故障时，可按下控制屏急停按钮，对机组进行立即停机。无特殊情况发生时，不能随意地通过急停按钮对机组进行停机操作。

Once the operator finds that the unit has serious fault or power distribution failure, he can press the emergency stop button on the control panel to stop the unit immediately. When there is no special situation, it is not allowed to stop the unit by emergency stop button.

5、正常停机

5. Normal shutdown

机组正常停机前，首先将负载分离（发电空开分断），然后将机组空载运行一定时间后（3～5 分钟），让机组得到充分冷却后停机。（冷却运行切勿在怠速下进行）

Before the normal shutdown of the unit, the load shall be separated first (the generator air switch is disconnected), and then the unit shall be shut down after the unit has been fully cooled after a certain period of no-load operation (3-5 minutes). (do not operate at idle speed)

关断控制屏钥匙开关使机组停止的操作是无效的。正确的停机操作，必须在控制屏上电时，按停机按钮才能使机组停止运行。

It is invalid to turn off the key switch of control panel to stop the unit. For correct shutdown operation, the unit can be stopped only by pressing the stop button when the control panel is powered on.

6、运行之后

6. After running

机组停机后，还有必要进行下列工作：

After the unit stops, it is necessary to carry out the following work:

a.检查机组有无“三漏”现象（润滑油、燃油、冷却液）。

a. Check the unit for "three leakage" (lubricating oil, fuel oil and coolant).

b.关闭燃油阀。

b. Close the fuel valve.

c.关闭机房进、排风设施（必要时）。

c. Close the air intake and exhaust facilities of the machine room (if necessary).

d.关闭发电机输出断路器。

d. Turn off the generator output circuit breaker.

e.关闭控制屏电源钥匙开关，取出钥匙，妥善保管（必要时）。

e. Turn off the power key switch of the control panel, take out the key and keep it properly (if necessary).

f.长时间停机或进行机组维护保养时，必须将机组启动电瓶负极电缆拆除，必要时还应放尽燃油和冷却液等。

f. When the unit is shut down for a long time or the unit is maintained, the negative cable of the starting battery of the unit must be removed. If necessary, the fuel and coolant should be drained.
