After the engine starts up, warm up it under unload for approx. five 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 a 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 unit or to be burned.
4.7.1 Procedure to start the unit
Follow the starting procedure below.
<Start engine>
① Make sure that both circuit breaker
(dedicated to single phase)“1”and circuit
breaker“2”are“OFF”.
② Turn the starter switch“5”to“RUN”.
Then glow lamp“7”glows.
Immediately when the glow lamp“7”
switches off, fully turn the starter switch
“5”clockwise to start engine. Engine rpm
rises up to the rated rpm.
③ Once the engine has started up, leave the
engine running to warm up for
approximately 5 minutes.
<Check and confirm voltage and frequency>
① After warming up operation, switch
operation mode selection switch“6”to
“RUN”position.
② Check the frequency meter“9”. When the
meter indicates wrong Hz, correct it and
set it to your desired frequency, using the
frequency selector switch“8”.
③ While watching the voltmeter“4”, turn the
voltage adjuster“3”knob to set the voltage
to the rated.
④ Output display lamp is displayed in
accordance with the selected output. 200V
output lamp glows in green“10”, and 400V
lamp in red“11”.
<Loaded operation>
① Switch circuit breaker (dedicated to single phase) “1”or circuit breaker“2” “ON”, then supply
power to the load.
② During operation, check and confirm whether the generator functions properly, according to the
table on next page.
※ Before starting to supply power to the load, make sure that the voltage is in accordance with the load.
