Do not use floodlight together with other machines.
9. 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 under 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
heave-duty motor should be connected, and 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 phases during the operation. Stop the engine for check if the tolerances
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 phases asynchronous motors, first start the heavy-duty
motors, and 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.
6. STOP PROCEDURE
1. Set the main switch to OFF.
2. Turn the breaker to the OFF.
3. Turn the start switch to the STOP position after running for 1-3 minutes with
zero load, then the generator stopped.
First disconnect the unit and load, then stop the generator.
