suddenly. It is necessary to unload immediately and to turn off the generator switch.
Check where the trouble appears.
If the circuit overload makes that the air switch of AC circuit trips, it is necessary to
reduce the circuit load. It is not allowed that the set runs under the overload condition.
Maximum output power of the generation for the set should not exceed the stipulation .It is
necessary to wait for several minutes before restoring the operation. If the indication on the
voltmeter is too low or too high, the revolution speed can be adjusted. If there is any trouble
and any abnormal running condition, it is necessary to stop the generator for check.
2.7.3 DC application
DC terminals are used only for charging 12V battery.
At the time of using 12Vfor charge, the air switch should be set at "OFF" state. On the
12Voutput terminals, a charge switch can be connected so the switch can be used for
on-and-off purpose.
At the time of using the automatic type battery with the battery conductors, be sure that
the battery negative conductor should be disconnected at the time of charge.
Connect the positive and negative poles of the battery with the positive and negative
poles of DC terminals separately. Do not misconnect the positive and negative poles of
the battery. Otherwise it will damage the generator and the battery.
Do not connect the positive pole of the battery with its negative pole. Otherwise it will
damage the battery.
Do not let the positive and negative poles of the DC contact each other. Otherwise it will
damage the generator.
At the time of charging the large capacity battery, because the current is too big (the
charge current should not be more than 10A). Otherwise the fuse of the DC power supply
will be burned off and broken easily.
Charging the battery will produce the flammable gas. Do not let any spark, flame and
cigarette approaching the place. In order to avoid producing the spark near the battery.
Firstly connect the charging conductors with the battery, then with the generator. At the
time of disconnection, firstly disconnect the motor cable.
Charging the battery should be at a place with good ventilation. Before turning on, open
the battery cover. If the electrolyte temperature exceeds 45℃, terminate the charge.
In order to protect the motor, at the terminals of the generator, the generator set has a fuse.
When the user find that the circuit is normal and there is no DC output, please open the
back cover of the motor. If the fuse is burned out, please check whether the
rectification-bridge is normal and change the fuse in time. If the generator set is not in use
for a time, the battery connection lines should be removed to prevent the electric leakage
of the battery.
2.8 Braking the Generator Set
2.8.1 Remove the load of the generator set.
2.8.2 Turn off the air switch of the generator set.
2.8.3 Set the speed handle of the engine to "RUN" position. Carry out the unload operation of
the diesel engine for there minutes. Do not brake the diesel engine suddenly because this may
make that the temperature goes up abnormally to cause the blocking-up of the oil nozzle and
