4) Check if there is any abnormal noise or vibration and check connection and
fastening condition of various parts;
5) Check if exhausting is normal or not. Belching of small amount of black smoke
immediately after starting of the Gen-set is normal.
If the Gen-set is equipped with idling/rated speed switch and operates normally after
being started, turn throttle control handle of diesel engine to “RATED SPEED”
position and lock it after the Gen-set has operated under idling state for 3~5min.
If the Gen-set is not equipped with idling/rated speed switch, the Gen-set will
automatically increase to rated speed in about 30~45s after being started.
After the Gen-set reaches to rated speed, check operation state of the Gen-set again.
Main checking contents are as follows:
1) Check speed and frequency of the Gen-set (normal speed and frequency of the
Gen-set is separately 1530~1560r/min and 51~52Hz). If speed and frequency of
diesel engine is lower than 1,530r/min or 51Hz, it need to adjust and lock throttle
control handle to increase speed of diesel engine to approximately 1530~1560r/min
(frequency 51~52Hz);
2) Check voltage of three-phase output line of the Gen-set. Voltage of each line shall
be 400V;
3) Check if water temperature and oil pressure of the Gen-set is normal or not. Water
temperature shall be lower than 95 and oil pressure shall be higher than 0.15Mpa;
℃
4) Check if lines of fuel, lubrication and cooling system leak or not;
5) Check if belched smoke is normal. Belched smoke of the Gen-set shall be colorless.
