YOURGEN
The WINCO YourGen meter allows you to see useful information about
your generator from the front panel by displaying RPMs, Voltage,
frequency, load, hours, and maintenance reminders. It also has the
ability to display warnings if any parameter gets outside of normal
operation range.
Cycle Button ( ) -
During normal operation, the display will toggle through on fixed delay.
If you want to see any specific item, you can press the cycle button to
move it to that setting. Once the display is selected, the delay before it
starts toggling is approximately 5 seconds. This button is also used to
reset maintenance reminders.
RPM -
The meter will display the RPMs of the engine. This number is
calculated based upon frequency and is not directly measured from the
engine. The engine-generator must be run at the correct speed in order
to produce the proper electrical voltage and frequency.
CAUTION: EQUIPMENT DAMAGE
The output voltage should be checked to ensure the generator is
working properly prior to connecting a load to the generator. Failure to
do so could result in damage to equipment plugged into the unit and
possible injury to the individual.
Operating Speed
All engines have a tendency to slow down when a load is applied.
When the electrical load is 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 running no load. The slight
variation in speed also affects the frequency of the output current.
This frequency variation has no appreciable effect in the operation of
motors, lights, and most appliances. However, electronic equipment
and clocks will be affected if correct RPM is not maintained. See Load
vs. Output chart.
Although individual units and models vary slightly, the normal voltage
and frequency of the engine-generator described in this manual are
approximately as follows, under varying loads:

To connect these units directly to an un-powered, isolated construction
site TemPower panel, have your electrician connect to the control panel
using a 120/240 Volt, 4-wire twist-lock plug (14-60P).
NOTE:
Never attempt to use the 240 Volt 3-wire receptacle to wire into
a building. This is a GFCI circuit and is designed for 240 Volt output
only. It has no neutral connection. If you attempt to draw 120 Volt from
this receptacle, the GFCI breaker will trip.
2. If the generator set is connected to an existing distribution system,
a fully isolated manual transfer switch must be installed. The transfer
switch prevents damage to the generator and the other circuit
components if main line power is restored while the generator is
connected. Installing a transfer switch also permits the use of normal
fusing.
3.Many homes and construction sites are wired for at least 60 to 100
Amp entrance service, much greater than the capacity of this portable
generator. When installing the generator at these sites, a secondary
emergency distribution panel may have to be installed. The emergency
distribution panel must be installed by a licensed electrician according
to all applicable codes. The electrician will move the critical circuits to
be powered during the outage to the emergency panel. Keep in mind
only a limited amount of amperage is available from the generator set.
Some circuit breakers may still have to be turned off to prevent an
overload on the generator during the initial start up. See the nameplate
on your generator for the amperage capabilities of your unit.
CAUTION: EQUIPMENT DAMAGE
Failure to properly limit and balance the load applied to the generator
will cause the generator to produce low voltage and may damage
the engine generator set. It may also cause severe damage to the
loads connected to the generator at that time. Improper loading of the
generator set constitutes abuse and will not be covered by warranty.
