LOAD
NOTE
Do not start 2 or more machines simultaneously. Start them one by one.
Do not use floodlights together with other machines.
First start the motor load, and then start resistance load.
6.1 AC application
1. Be sure to run the generator 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 generator set; 400V
5% (50Hz) for three-phase generator set, then
the loading can be carried out.
3. When the double voltage generator set changes over the voltage, the air
switch should be set at "OFF" position. Otherwise the generator set and
electric devices will be burned out and damaged.
4. Connect the equipment to the generator set in order. For the matter of the
motor land, firstly the heavy-duty motor should be connected, then the light-
duty motors. If the operation is false, the generator set will lag or stop
suddenly. It is necessary to unload the generator set immediately and turn off
the main switch and do checks.
5. Three-phase generator set
Balance three phases 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.
CAUTION
6.2 DC application
1. DC terminals are only for charging 12V battery.
2. Set the air switch at "OFF" position while charging. On the 12V output
terminals, a charge switch can be connected so the switch can be used for on-
and-off purpose.
3. Concerning the automatic type battery with the leads, be sure to disconnect the
negative leads of the battery while charging.
CAUTION
Connect the positive and negative poles of the battery with the positive and
negative poles of DC terminals separately. Do not confuse them, otherwise
the battery and generator set will burn out.
Do not connect the positive pole of the battery with its negative pole,
otherwise the battery damage will result.
Do not connect the positive pole of the DC terminal with its negative pole,
otherwise the generator set damage will result.
When a large capacity battery is charged, excessive current flows, the fuse
for the direct current will burn out.
Do not run the generator set while it is still connected with the battery.
Do not use DC12V and AC at the same time.
Battery exhausts explosive gas. Keep sparks, flames, and cigarettes
away form the battery. To prevent from creating a spark near the battery,
always connect the charging cables to the battery first and only then to
the generator set. When disconnecting, you should disconnect the cables
at the generator set first.
Charge the battery at a well-ventilated place.
Before charging, remove the cap from each cell of the battery.
Stop charging if the electrolyte temperature exceed 45
