4-3 DESCRIPTION of GENERATOR OPERATION
4-3-1 PRIMARY EXCITING ACTION
(RGV12100)
AVR
When the generator is started, the perma-
nent magnet on the engine rotates to genera-
tor a voltage in the exciting coil.
FC
This voltage is regulated by a diode in the
AVR to feed a current to the generator field
coil. (FC). (See Fig. 4-1)
a
EC
The rotor is turned an electromagnet by that
current and rotates so that voltage are gener-
ated in the stator coils (main coil and sub
coil). The voltage generated in the sub coils
is operated by the AVR to feed a current to
increase the field coil current. (See Fig. 4-2)
As a result, the rotor magnetism increases.
This operation is repeated to generate the
rated voltage at 50 Hz or 60 Hz in the main
coil and DC coil.

4-3-2 VOLTAGE REGULATING MECHANISM
(RGV12100)
b
FC
AVR
Connect a load to the AC output terminal and
increase current. Output voltage varies as
shown in Fig. 4-3 depending on whether an
automatic voltage regulator is used or not.
The operation of the AVR is explained below.
When an AC output is taken, the engine is
loaded and its rpm falls, Also the AC voltage
fails due to the voltage drop caused by the
internal resistance of the coils. The AVR
detects this voltage drop and its built-in SCR
automatically increase the current flows to
the field coil. As a result, the rotor magnetism
increase, the voltage fallen by the load cur-
rent is raised, and the output voltage is kept
constant. If the AC output is reduced, the
SCR operates in the opposite way to similarly
keep the output voltage constant.

4-3-3 CURRENT TRANSFORMER CONTROL (RGV13100T)
When the engine starts, a permanent magnet implanted in the rotor rotates, creating voltage in
the main coil (MC). When a load makes contact with the coil, the load current passing through
the primary coil of current transformer causes a magnetizing current to flow in ratio to the load
current flowing through the current transformer primary coil. This magnetizing current passing
through a diode to field coil creates a strong magnetic field in the rotor which falls with the
amount of the load, increasing the voltage.

4-3-4 THE ADVANTAGES OF CURRENT TRANSFORMER CONTROL (RGV13100T)
With AVR control, control is effected according to variations in output voltage.
When an inductive load is applied, a large starting current is required (current variations are
greater than voltage variation), precise control becomes difficult.
Current transformer control, on the other hand, controls the output voltage according to the
load current, which is better for using inductive load.

5. SAFETY PRECAUTIONS
1. Use extreme caution near fuel. A constant danger of explosion or fire exists.
Do not fill the fuel tank while the engine is running. Do not smoke or use open flame near the
fuel tank. Be careful not to spill fuel when refueling. If spilt, wipe it and let dry before starting
the engine.
2. Do not place inflammable materials near the generator.
Be careful not to put fuel, matches, gunpowder, oily cloth, straw, and any other inflammables
near the generator.
3. Do not operate the generator in a room, cave or tunnel. Always operate in a well-venti-
lated area.
Otherwise the engine may overheat and also, the poisonous carbon monoxide contained in
the exhaust gases will endanger human lives. Keep the generator at least 1 m (3 feet) away
from structures or facilities during use.
4. Operate the generator on a level surface.
If the generator is tilted or moved during use, there is a danger of fuel spillage and a chance
that the generator may tip over.
5. Do not operate with wet hands or in the rain.
Severe electric shock may occur. If the generator is wet by rain or snow, wipe it and thor-
oughly dry it before starting.
Don't pour water over the generator directly nor wash it with water.
If the generator is wet with water, the insulation s will be adversely affected and may cause
'
current leakage and electric shock.
6. Do not connect the generator to the commercial power lines.
This may cause a short-circuit or damage to the generator.
7. Be sure to check and remedy the cause of circuit breaker tripping before re-setting it
on.
CAUTION : If the circuit breaker tripped off as a result of using an electrical appliance,
the cause can be an overload or a short-circuit. In such a case, stop opera-
tion immediately and carefully check the electrical appliance and AC plugs
for faulty wiring.

6. RANGE OF APPLICATIONS
Generally, the power rating of an electrical appliance indicates the amount of work that can be
done by it. The electric power required for operating an electrical appliance is not always equal
to the output wattage of the appliance. The electrical appliances generally have a label show-
ing their rated voltage, frequency, and power consumption(input wattage). The power con-
sumption of an electrical appliance is the power necessary for using it. When using a generator
for operating an electrical appliance, the power factor and starting wattage must be taken into
consideration.
In order to determine the right size generator, it is necessary to add the total wattage of all
appliances to be connected to the unit.
Refer to the followings to calculate the power consumption of each appliance or equipment by
its type.
(1) Incandescent lamp, heater, etc. with a power factor of 1.0
Total power consumption must be equal to or less than the rated output of generator.
Example : A rated 3000 W generator can turn thirty 100W incandescent lamps on.
(2) Fluorescent lamps, mercury lamps, etc. with a smaller power factor
Select a generator with a rated output equivalent to 1.2 to 2 times of the power consump-
tion of the load.
Example : A 400W mercury lamp requires 600 W to 700 W power source to be turned on.
A rated 3000 W generator can power four or five 400 W mercury lamps.
NOTE 1 : If a power factor correction capacitor is not applied to the mercury lamp or fluorescent
lamp, the more power shall be required to drive those lamps.
A rated 3000W generator can drive one or two 400W mercury lamps without power fac-
tor correction capacitors.
NOTE 2 : Nominal wattage of the fluorescent lamp generally indicates the output wattage of the
lamp.
Therefore, if the fluorescent lamp has no special indication as to the power consumption,
efficiency should be taken into account as explained in item (5) on the following page.
(3) Motor driven tools and light electrical appliances
Generally the starting wattage of motor driven tools and light electrical appliances are 1.2
to 3 times lager than their running wattage.
Example : A rated 250 W electric drill requires a 400 W generator to start it.
(4) Initially loaded motor driven appliances such as water pumps, compressors, etc.
These appliances require large starting wattage which is 3 to 5 times of running wattage.
Example : A rated 900 W compressor requires a 4500 W generator to drive it.
NOTE 1 : Motor-driven appliances require the aforementioned generator output only at the starting.
Once their motors are started, the appliances consume about 1.2 to 2 times their rated
power consumption so that the excess power generated by the generator can be used for
other electrical appliances.

NOTE 2 : Motor-driven appliances mentioned in lets (3) and (4) vary in their required motor starting
power depending on the kind of motor and start-up load. If it is difficult to determine the
optimum generator capacity, select a generator with a larger capacity.
(5) Appliances without any indication as to power consumption
Some appliances have no indication as to power consumption; but instead the work load
(output) is indicated. In such a case, power consumption is to be worked out according to
the numerical formula mentioned below.
(Output of electrical appliance)
(Power consumption)
＝
(Efficiency)
Efficiencies of some electrical appliances are as follows:
Single-phase motor ・・・・・・・・・ 0.6 to 0.75
The smaller the motor, the lower
the efficiency.
Three-phase motor・・・・・・・・・・ 0.65 to 0.9
Fluorescent lamp・・・・・・・・・・・ 0.7 to 0.8
Example 1 : A 40 W fluorescent lamp means that its luminous output is 40W. Its efficiency is
0.7 and accordingly, power consumption will be 40 0.7=57W. As explained in
÷
Item(2), multiply this power consumption value of 57 W by 1.2 to 2 and you will
get the figure of the necessary capacity of a generator. In other words, a genera-
tor with a rated output of 1000 W capacity can light nine to fourteen 40W fluores-
cent lamps.
Example 2 : Generally speaking, a 400 W motor means that its work load is 400 W.
Efficiency of this motor is 0.7 and power consumption will be 400 0.7=570 W.
÷
When this motor is used for a motor-driven tool, the capacity of the generator
should be multiple of 570W by 1.2 to 3 as explained in the Item (3).

NOTES : Wiring between generator and electrical appliances
1. Allowable current of cable Use a cable with an allowable current that is higher than the rated
input current of the load (electrical appliance). If the input current is higher than the allowable
current of the cable used, the cable will become excessively heated and deteriorate the insula-
tion, possibly burning it out.
Table 7-2 shows cables and their allowable currents for your reference.
2. Cable length
If a long cable is used, a voltage drop occurs due to the increased resistance in the conduc-
tors decreasing the input voltage to the load (electrical product). As a result, the load can be
damaged.
Table 7-2 shows voltage drops per 100 meters of cable.

7. MEASURING PROCEDURES
7-1 MEASURING INSTRUMENTS
(1) VOLTMETER
AC voltmeter is necessary.
The approximate AC voltage ranges of
the voltmeters to be used for various
types of generators are as follows :
0 to 150 V : Type with an output voltage
of 110 or 120 V
0 to 300 V : Type with an output voltage
of 220, 230 or 240 V
0 to 150 V, 0 to 330 V : Dual voltage type
FOR AC
(2) AMMETER
AC ammeter is necessary.
An AC ammeter with a range that can be
changed according to the current rating
of a given generator is most desirable.
(About 10 A, 20 A, 100 A)
FOR AC
(3) FREQUENCY METER
Frequency range : About 45 to 65Hz
NOTE : Be careful of the frequency meter's input
voltage range.

7-3 MEASURING INSULATION RESISTANCE
Use a megger tester to check the insulation
resistance. Connect a megger tester to one
of receptacle output terminals and the ground
terminal, then measure the insulation resis-
tance.
Ω
An insulation resistance of 1M or more is
normal.
Ω
If it is less than 1M , disassemble the gen-
erator and measure the insulation resistance
of the stator, rotor and control panel individu-
ally.
●
STATOR
(1) Measure the insulation resistance
between BLUE (RGV12100),
GREEN (RGV13100T) lead and the core.
(2) Measure the insulation resistance
between WHITE lead and the core.
(3) Measure the insulation resistance
between BLACK lead and the core.
(4) Measure the insulation resistance
between RED lead and the core.

8. CHECKING FUNCTIONAL MEMBERS
8-1 PILOT LAMP and VOLTMETER
Check the pilot lamp and the voltmeter if it is
turned on by applying specific voltage.
Pilot lamp and voltmeter cannot be checked
with circuit tester because its resistance is
PILOT LAMP
too large.
8-2 AC RECEPTACLES
Using a circuit tester, check continuity
between the two terminals at the rear of the
AC receptacles while the receptacle is
mounted on the control panel. When continu-
ity is found between the output terminals of
the receptacle with a wire connected across
these terminals, the AC receptacle is normal.
When the wire is removed and no continuity
is found between these terminals, the recep-
tacles are also normal.

8-3 AC SWITCH (NO-FUSE BREAKER)
Check continuity between each of 2 terminals at the back side of AC switch (no-fuse breaker)
while it is mounted on the control panel.
Normally, there is continuity between each of the 2 terminals when the breaker is ON, while no
continuity when the breaker is OFF.
RGV12100
RGV13100T
8-4 STATOR
Disengage connectors on the wires from stator and check the resistance between wires with a
circuit tester, referring to the following specification table.
NOTE : If the circuit tester is not sufficiently accu-
rate, it may not show the values given and
may give erroneous readings.
Erroneous readings will also occur when
there is a wide variation of resistance
among coil windings or when measure-
ment is performed at ambient tempera-
℃
tures different from 20
(68 F).

2) Cleaning Slip rings
SLIP RING
The slip ring surfaces must be uniformly
bright. Slip rings showing black spots,
excessive wear, or uneven wear must be
repaired. A stained slip ring lowers gener-
ator efficiency and output voltage. Polish
the slip rings with fine sandpaper while
turning the rotor until rough spots disap-
pear. Care should be taken not to touch
the rotor coils with the sandpaper.
SANDPAPER
8-6 EXCITING COIL (RGV12100 only)
1) Disconnect the two yellow wires which
come out from the exciting coil through the
hole of the crankcase and connected with
A.V.R. in the control box.
2) Check the resistance between two yellow
wires with a circuit tester.
Exciting coil for A.V.R.

8-7 BRUSH
The brushes must be smooth where they
contact the slip rings. If not, polish smooth
the brushes with sandpaper. A brush that is
not smooth produces arcs between the brush
and slip ring leading to possible damage.
Usable brush lengths are from 5 mm to 15
mm (0.2 " to 0.6").
BRUSH
HOLDER
15 to 5 mm
(0.6" to 0.2")
A brush shorter than 5 mm must be replaced
because decreased contact pressure
between the brush and slip ring lowers gen-
erator efficiency and output voltage.

2) A.V.R. trouble may be identified by simply
looking at the A.V.R., or by the inter-lead
resistance with a tester, or actually mount-
ing it in the generator and operating it.
(a) A.V.R. TROUBLE IDENTIFICATION by APPEARANCE
If an A.V.R. electronic part is burnt dark, or the surface epoxy resin melted, it often indi-
cates A.V.R. trouble.
(b) IDENTIFYING A.V.R. TROUBLE by CHECKING INTER-LEAD RESISTANCE
Check the inter-lead resistance of the A.V.R. with a tester, referring to the following table.
If the tester readings very greatly from the values specified in the table on next page, the
A.V.R. is faulty.
NOTE : Take teater inaccuracy into account in reading the tester.
(c) IDENTIFYING A.V.R. TROUBLE by MOUNTING and OPERATING in THE GENERATOR
SCR or transistor damage cannot be detected by simply looking at the A.V.R. or checking
the lead resistance. Check it by mounting the suspectedly faulty A.V.R. in a normal gener-
ator, or mount a mormal A.V.R. in a generator which fails to generate voltage.

9. DISASSEMBLY AND ASSEMBLY
9-1 PREPARATION and PRECAUTIONS
1) Be sure to memorize the location of individual parts when disassembling the generator so
that the generator can be reassembled correctly. Tag the disassembled part with the neces-
sary information to facilitate easier and smoother reassemble.
2) For more convenience, divide the parts into several groups and store them in boxes.
3) To prevent bolts and nuts from being misplaced or installed incorrectly, replace them tem-
porarily to their original position.
4) Handle disassembled parts with care; clean them before reassemble using a neutral clean-
ing fluid.
5) Use all disassembly / assembly tools properly, and use the proper tool for each specific job.
