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).
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.
Function Warning lamp Electric starter control Fail-safe function Self checking function for warning lamp bulb Description of Operation When the lubrication oil pressure drops below the safety limit (Oil pres- sure becomes less than 1 kg/cm2), the warning lamp turns on and off, and the engine stops automatically.
4-2-8 OIL PRESSURE SWITCH The oil pressure switch sends a signal to ECU to stop the engine when the engine oil pressure drops to 1 .O kg/cm2 .r? 4-2-9 RELIEF VALVE The relief valve begins to open when the engine’s oil pressure increases above 3.
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. another, are used. As many AC terminals as the receptacles, each matching the corresponding receptacle, are provided.
n Check the amperage of the receptacles used referring to TABLE 1, and be sure not to take a current exceeding the specified amperage. n Be sure that the total wattage of all appliances dose not exceed the rated output of the gen- erator.
If the RESET button pops out during operation, stop the generator immediately and call a qualified electrician for checking generator and the appliances. (2) CONNECTING TO DOMESTIC CIRCUIT (HOUSE WIRING) All Robin generators are a neutral ungrounded type.

(1) 3-Phase application (208V) Connecting the power cable&o terminals U, V and W. 1 Generator rated output : 1OOOOVA 1 (2) Single phase higher voltage application (208V) Connect the power cables to-terminals U and V, V and W, and U and W. Maximum one-second (l/2) of generator output can be utilized from each phase.
4-3 DESCRIPTION of GENERATOR OPERATION 4-3-l PRIMARY EXCITING ACTION (RGV12000) When the generator is started, the perma- nent magnet on the engine rotates to genera- tor a voltage in the exciting coil. This voltage is regulated by a diode in the AVR to feed a current to the generator field coil.
4-3-3 CURRENT TRANSFORMER CONTROL (RGV13000T) When the engine starts, a permanent magnet implanted in the rotor rotates, creating voltage in the main coil (MC).
5. SAFETY PRECAUTIONS 1. Use extreme caution near fuel. A constant danger of explosion or fire exists. r- 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.
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.
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 capaciv, select a generator with a larger capacity.
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).
7. MEASURING PROCEDURES 7-l 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.
(4) CIRCUIT TESTER Used for measuring resistance, etc. (5) MEAGER TESTER Used for measuring generator insulation resistance. Select one with testing voltage range of 5oov. 7-2 AC OUTPUT MEASURING TO AC Use a circuit above for measuring AC output. A hot plate or lamp with a power factor of 1 .
.
L_ . ROTOR a Measure the resistance between the slip ring and the core. . CONTROL PANEL Measure the insulation resistance between the live parts and the grounded parts. . CURRENT TRANSFORMER (RGV13000T) Measure the insulation resistance between each terminal and the core.
8. CHECKING FUNCTIONAL MEMBERS 6-l 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 too large.
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.
8-5 ROTOR ASSEMBLY 1) Field coil Remove the brush holder and measure resistance between the slip rings. Rotor (Slip ring) Resistance RGV12000 4.11Q RGV1300dT 69.6 Q NOTE : If the circuit tester is not sufficiently accu- rate, it may not show the values given and may give erroneous readings.
8-6 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.
8-8 CURRENT TRANSFORMER (RGV13000T only) Disconnect the connectors and coupiers of current transformer. Check the inter-terminal resistance of current transformer with a circuit tester. If current transformer is found to be faulty, replace with new one.
8-10 IDLE CONTROL UNIT (RGV12000 only) Check the resistance between five terminals of IDLE CONTROL UNIT with circuit tester. Terminal number of the IDLE CONTROL UNIT Circuit tester (with battery power source 1.
8-11 DIODE UNIT (RGV13000T only) Check the resistance between five wires of DIODE UNIT with circuit tester. Diode unit needle of the cir- cuit breaker 9.
