3. The generator switch can be closed once the rated speed is ready. Normally, the idle speed can be get .
in 20 or 30 seconds after pressing the start button. This time depends on the batteries conditions and
ambient temperature mainly.
In case of generated connected to the grid, the synchronize process must be carried out to close the
switch. The synchronization time will dependo n the stability of the grid parameters.
4. Load applications must be according to the product information:
-
IC-G-B-00-002 for engines at 1500 rpm
-
IC-G-B-00-003 for engines at1800 rpm
Minimum time between loads application of 5 seconds.
CAUTION
Do not operate a turbocharged engine for prolonged periods (fifteen minutes or above) at light load or idle.
Under this condition the turbocharger may be damaged by the accumulation of carbon, which does not have
a chance to burn off completely.
5. Operating inspection: There are series of important aspects, which must be checked while the engine is
in operation:
-
Examine the water, fuel and oil conduits in case of leaks, mechanical damage or corrosion.
-
Inspect the level and status of coolant. The presence of rust, foam or oil in the coolant indicates the
need to overhaul the circuit.
-
Observe and note down the operating parameters. Variations with regard to the normal values may
indicate that anomalies are occurring.
-
Listen to the sound of the engine. Some problems such an occasional false explosions, failures of the
turbocharger bearings or problems with the water pumps, may be detected at the outset by unusual
sounds from the engine.
3.3. Engine Shut-down
1.
Reduce the load gradually.
2.
Open the generator switch once the load is off.
3.
Before stopping an engine after having been operating in severe loading conditions, you should make
spinning without charge or idle for 5 to 10 minutes to stabilize at moderate levels the temperatures of
the various components of the turbocharger, valves and other engine parts
CAUTION
Before doing anything to the engine, let it cool for at least ten minutes after shut-down.
4. Check the fuel supply has been cut off at the engine.
