3-15
<Check frequency and voltage>
1.
After finishing warming up operation, check and confirm frequency meter [F].
2.
While watching the voltmeter [G], turn the voltage adjuster [H] knob to set the voltage to the rated.
(See 3.6.2)
3.
The power indicator light [I] is lighted green during operation.
<Operation with Load>
1.
Set the Three-phase circuit breaker [A] and Single-phase circuit breaker [B] to [ON] and supply
power to the load.
2.
During operation, check and confirm whether the generator functions properly.
(See. Next page)
※
Before starting to supply power to the load, make sure that the voltage is in accordance with the load.
After the engine starts up, warm it up unloaded for approx. 5 minutes.
Warming up after starting up is necessary for smooth operation of the engine.
Do not operate the engine at full load immediately after it starts up.
This will shorten the equipment life.
During the warm-up operation, examine the different parts of the equipment for any looseness, leakage
of water, oil, fuel, and other irregularities.
Also, make sure that the alarm lamps are off.
Be sure to operate the generator at the rated frequency, irrespective of the load capacity.
If the machine is operated with a frequency lower than the rated frequency, it could cause the generator
main machine or to be burned.
