If there is no auto stop function which is more easier, select both engines in manual mode.
>> The panel will have fuel control selector for each engine, you can increase the fuel to DG#1, which will start taking in more load and the DG#2 will start dropping.
>> Go up to 10-15% load on DG#2 capacity, stop at that point as going further below may cause the engine to reverse power or trip on reverse power
>> Now, open the breaker of DG#2, DG#1 will take the complete load.
>> If we don’t reduce the load below 15%, the incoming generator voltage will fall seriously below, over current trip or low voltage trip may occur! its always better to reduce the load to safe low voltage.
