the
air switch should be set at
“
OFF
” postion. 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 phases during the operation. Stop the engine for check if the toler-
ance 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 heavyduty
motors, then start the light-duty motors.
NOTE
If coverloading of the circuit trips the AC circuit protector, reduce the electrical
load on the circuit, and wait a few minutes before resuming operation.
6.2 DC applicetion
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.
