Cummins Diesel Generator Set Shutdown

Diesel generator set shutdown

① Cummins Generator normal shutdown

a. Stop: The unit controlled by the automatic module can stop normally by pressing the stop button by hand; the manually controlled unit can only turn the key to the “STOP” position, and can also achieve normal shutdown.

b. Before shutdown, the load must be unloaded, and it is strictly forbidden to stop with load. In general, after unloading the load, the diesel genset needs to run for 3 to 5 minutes without load before stopping.

c. When the load cable is connected or removed, the battery's negative wiring must be turned off and removed.

② Genset emergency shutdown

a. The unit must be shut down immediately if abnormal noise or odor is emitted during start-up or operation.

b. When the unit oil pressure suddenly drops to the limit or no oil pressure, the fault light is red and must stop immediately.

The machine must stop immediately:

a. When the unit water temperature suddenly rises above the specified value and the fault light is red.

b. When the unit output voltage exceeds the maximum reading on the meter.

c. When there is a fire, electric leakage or other natural disaster that may endanger the safety of the crew and operators.

At this point, press the emergency stop button or push the stop control handle of the fuel pump to the stop position rapidly , the unit will quickly cut off the load, and immediately turn off the throttle, while the red "emergency stop" indicator light is on. The button needs to be re-screwed to release the emergency stop signal. When the power generating set is in normal operation or is supplying power to the equipment, if there is no special emergency, it is recommended that the user do not perform emergency shutdown operation at will.

After shutdown

a. Check for leaks in the engine and machine room.

b. Close the fuel valve

c. If the unit is to stop for a period of time, turn off the main switch.

d. Long-term shutdown should drain fuel and cooling water, and periodically charge the battery according to maintenance specifications.

e. When the ambient temperature is lower than 5°C, the unit after shutdown must do antifreeze measures to avoid freezing cracking of the body and water tank.
