The speed of the engine was carefully adjusted at the
factory so that the generator produces the proper voltage
and frequency. For normal usage, the speed setting
should not be changed. If the generator is being run
continuously on a very light load, it is often advisable to
lower the operating speed slightly. Whenever making any
speed adjustments check the unit with a voltmeter or
tachometer and be sure the speed is correct.
The engine will govern itself at full speed. Intentionally
overriding the governor and operating the generator at low
voltage may damage both the generator and any load
connected to it. Running the engine at excessively high
speeds results in high voltage, which may significantly
shorten the life of light bulbs and appliances being used,
as well as possibly damaging the engine.
Output voltage should be checked periodically to ensure
continued proper operation of the generating plant and
appliances. If the generator is not equipped with a
voltmeter, it can be checked with a portable meter.
Frequency can be checked by using an electric clock with
a sweep second hand. Timed against a wrist watch or a
stop watch the clock should be correct within +/- 2
seconds.
CONNECTING THE LOADS
1. Applying The Load - Allow the engine to warm up for two
or three minutes before applying any load. This will allow
the engine to reach normal operating temperature and oil
to circulate throughout the engine. A short warm-up time
will permit the engine to work more efficiently when the
load is applied and will reduce the wear in the engine,
extending its life.
a. The generator output is provided at the junction box
on top of the generator shell. Receptacles may have
been provided by the vehicle manufacturer for
convenient load connection. The loads should be
applied gradually. When starting large electric
motor(s), they should be started individually when
possible. The largest motor should always be started
first.
CAUTION: EQUIPMENT OVERLOAD
Keep the generator load within the generator and
receptacle nameplate rating. Overloading may cause
damage to the generator and/or the loads
b. Most electric tools and devices will have the voltage
and amperage requirements on their individual
nameplates. When in doubt consult the manufacturer
or a local electrician. The nameplate amperage rating
for electric motors can be misleading. See “Starting
Electric Motors” in Specification Section.
c. These engine generator sets are inherently self
regulating based on engine speed. The engine
governor will automatically adjust itself to the load. No
harm to the generator will result if it is operated with
no load connected.
d. Proper utilization of the generator output power is
necessary to prevent damage to either the tools or the
generator. The generator is a limited source of
electrical power, therefore pay special attention to the
generator ratings. The nameplate rating can be
obtained through a combination of all four generator
leads or a single lead pair as long as the current
capacity of the generator windings are not exceeded.
Both the 120 and 240 volt capabilities can be utilized
at the same time if so wired. See Specification
Section for proper load separation.
WIRING
These engine generator sets are designed for mobile
vehicular use. The generator output consists of two
independent 120 volt windings. These windings may be
connected in series to permit 120 and 240 dual voltage
availability, or in parallel to provide 120 volt only power at
higher amperage.
Please note that any standard 3 wire 240 volt receptacle
provided by the vehicle manufacturer is designed to power
only 240 volt tools. There are two hot and one ground
wire.... but no neutral connection in the 3 wire 240 volt
receptacle. Split 120/240 volt TemPower service on an
extension cord requires the installation of a 4 wire
receptacle (2 hot, 1 ground, and 1 neutral). Consult a
licensed electrician for wiring a TemPower plug and
splitting the cord output into 120 and 240 volt power
service.
To connect this unit directly to an un-powered, isolated
mobile vehicle distribution panel, have your electrician
wire the generator to the load(s) using one of the following
methods:
a. Connect the generator output to a distribution panel
using a fine strand (flexible) motor lead wire. Install a
mainline circuit breaker at the panel to protect the
generator output winding and distribution wiring. The
required breaker rating will depend upon the voltage
desired. Use a single pole 20 or 23 Amp breaker for
