4-2 FUNCTION

4-2-l STATOR

The stator consists of a laminated silicon
steel sheet core, a main coil and a condenser
coil which are wound in the core slots.
The condenser coil excites the rotor field coil
which generates AC voltage in the main coil. -

-6-

4-2-2

ROTOR

The rotor consists of a laminated silicon steel
sheet core and a field coil which is wound
over the core.

DC current in the field coil magnetizes the
steel sheet core.
Two permanent magnets are provided for the
primary exciting action (RGV13OOOT).

Slip rings are provided on the rotor shaft to

receive DC exciting current from AVR

(RGV12000) and diode unit (RGVl3000T).

A surge absorber is mounted inside of the

insulator.

4-2-3 BRUSH I BRUSH HOLDER

An exciting current is supplied from the A.V.R
to the rotor. The brushes are made of carbon

and the brush-holder of plastic.

It is necessary to keep the contact pressure

between the brushes and slip rings withing

specific limits. Thus, care must be taken of

brush length.

4-2-4 CURRENT TRANSFORMER

I DIODE UNIT (RGV13000T only)

The current transformer and diode unit will perform a role to step up the voltage lowered by the

load and stabilize the output voltage.

CURRENT TRANSFORMER

4-2-5 A.V.R

(AUTOMATIC VOLTAGE REGULATOR)
(RGV12000 only)

The automatic voltage regulator employs an

electronic circuit to automatically regulate
voltage.

4-2-6 ECU (ELECTRONIC CONTROL UNIT)

ECU controls the start/stop of an engine

enabling the fuel cut while stop.

It also automatically stops the engine if an

abnormal oil pressure occurs.

Function

Fail-safe function

Self checking function

for warning lamp bulb

Description of Operation

When the lubrication oil pressure drops below the safety limit (Oil pres­sure becomes less than 1 kg/cm2), the warning lamp turns on and off, and
the engine stops automatically. The warning lamp turns off after 3 minutes.

When the the engine started and reaches 1,050 rpm, the electric starter is
automatically stopped.

When the engine operating, the electric starter can not start.

When the key switch or the remote control switch is turned to ‘START”, the
fuel cut-off valve of the carburetor opens. When the key switch or the
remote control switch is turned to “STOP”, the fuel cut-off valve closes.

If the electric starter is locked by any reason, the electric starter is shut off
automatically after 3 seconds.

When the engine dose not start (engine speed dose not reach 1,050 rpm),
the electric starter is stopped after 21 seconds.

When the remote controller is connected, the electric starter dose not run
when the switch of remote controller is turned “OFF” even if the key switch
on the generator is turned to “START”.

When the key switch or remote control switch is turned to ‘START”, the
warning lamp lights up for a moment to indicate that the bulb for the warn-

ing lamp is normal.

4-2-7 IDLE CONTROL UNIT

(RGV12000 only)

The idle control unit has a function to check

that the generator has a load or not, then

decrease the engine rotation at no load or

increase it to the rated rotation.

The idle control unit releases throttle valve

when the applied load current exceeds

0.04A.

NOTE :

It is normal that the engine speed goes up for
a moment when you turn the key switch to
“STOP” while the Auto Idle Switch is in “ON”

position.

4-2-l 1 AC Receptacle and Terminals

AC receptacle and terminals are used for taking AC output power from the generator.
A total of 4 kinds of receptacle and terminals, each varying in rated voltage and current from.

receptacle, are provided.

The rated current for each receptacle and terminal is shown as follows;

CAUTION

Be careful not to use the receptacles and
terminal beyond the specified amperage
limits to prevent burning.

NOTE :

When the no-fuse breaker turns off during operation, the generator is over loaded or the appli­ance is defective. Stop the generator immediately, check the appliance and / or generator for
overloading or detect and have repaired as necessary by Robin dealer or service shop.

-[CAUTION]

The duplex 120V receptacle is protected by a GFCI (Ground Fault Circuit Interrupter).

GFCI shuts off the output current from the duplex 120V receptacle when a ground fault
occurs in the generator or the appliance.

Please note that other receptacles are not protected by GFCI.

GFCI RECEPTACLE

After starting the engine, check the GFCI for proper functioning by the following test procedure.

n

Push yellow TEST button, The red RESET button will pop out exposing the word TRIP.
Power is now off at the outlets protected by the GFCI, indicating that the device is functioning

properly.

m If TRIP dose not appear when testing, do not use the generator. Call a qualified electrician.

n

To restore power, push RESET button.
