6.1 AC application
1. Be sure to run the generating set at rated speed, otherwise AVR(Automatic Voltage
Regulator) will produce the forced excitation. If the running is for a long time unser such
condition,AVR will be burned out.
2. After switching on the air switch, observe the voltmeter on the panel of the control cabinet,
the voltmeter should point to 230V
±
5%(50Hz) for single-phase generating set;400V
±
5%(50Hz) for three-phase generating set, then the loading can be carried out.
3. When the double voltage generating set changes over the voltage, the air switch should be
set at
“OFF” position. Otherwise the generating set and electric devices will be burned out
and damaged.
4. Connect the equipment to the generating set in order. For the matter of the motor load, firstly
the heavy-duty motor should be connected, then the light-duty motors. If the operation is
false, the generating set will lag or stop suddenly. It is necessary to unload the generating set
immediately and turn off the main switch and do checks.
5. Three-phase generating set

Balance three phase during the operation. Stop the engine for check if the tolerance exceed
20%.Be sure to keep the tolerance among three phases less than 20%.

The load for each phase must below the rated load as well as the current must less than
rated current.
A,B,C,D(or U,V,W,N) phase arrangement should be from left to right, or clockwise.

Concerning starting the three phase asynchronous motors, first start the heavy-duty motors,
then start the light-duty motors.

If overloading of the circuit trips the AC circuit protector, reduce the
electrical load on the circuit, and wait a few minutes before resuming operation.
