i means what's happen in diesel generator while just switch on ?
I am trying to figure out what you are asking? Step 1 is guess is to press start? What are you looking for? One last guess,, did it start?
Depends whether it is a battery start or air pressure start. If it's started with a battery, the starter cranks the engine with an electric starter. If it is air started, a solenoid valve is energized, or a hand valve is opened to allow the air pressure to crank the engine with an air turbine. That's the first occurance. There is a definite start-up sequence, in the event the engines fails to start within a given time frame.
