Operation (cont’d)
31
Note: Expect slight variations in voltage/speed with changing electrical
loads. All engines have a tendency to slow down when a load is
applied. When electrical loads are connected to the generator, the
engine is more heavily loaded and as a result the speed drops slightly.
This slight decrease in speed, together with the voltage drop within
the generator itself, results in a slightly lower voltage when the
generator is loaded to its full capacity than when it is running with no
load. Additionally, there may be small brief surges and drops in
voltage as motors connected to the generator cycle on or off.
The slight variation in voltage has no appreciable effect in the
operation of motors, lights, and most appliances, as long as the
voltmeter’s needle remains in the green area.
Using as a
Back-up Power
Source for a
Building Written instructions for how to safely bring the generator online with the
building’s electrical system should be provided by the electrician who
installs the transfer switch, and who should also provide personal instruction
to the owner/operator.
Failure to follow the proper procedure as provided by the electrician could
expose persons to the hazards noted above.
Note: After you have brought the generator online with the transfer switch,
you may need to adjust engine speed to maintain correct output voltage
under load. (See more detail about maintaining proper voltage in the
instructions given above for using the generator as a portable power
source.)
5. Stopping
Stop the generator using the following steps:
1. Disconnect all loads to generator.
(Never turn off or reduce engine speed with electrical loads connected. Damage to generator
and loads will occur.)
2. Shut OFF the engine
3. Shut OFF fuel supply to the engine if possible.
4. Remove spark plug to prevent accidental starting of engine.
