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. (FC). (See Fig. 4-1) The rotor is turned an electrom[...]

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). 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 t[...]

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. If spilt, wipe it and let dry before starting the engine. 2. Do not place inflammable mate[...]

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, [...]

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. .-. (5) Appliances without any indication as to power consumption Some appliances have [...]

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 insui[...]

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 : 0 to 150 V : Type with an output voltage ofllOor120V 0 to 300 V : Type with an output voltage of 220,230 or 240 V 0 to 150 V, 0 to 330 V : Dual vol[...]

(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 .O may be used as a load. Adjust-the load and rpm. and che[...]

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. 8-2 AC RECEPTACLES Using a circuit tester, check continuity between the two terminals at the rear of t[...]

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. WY RGV12000 RGV13000T 8-4 STATOR Disengage connector[...]

Erroneous reading will also occur when there is a wide var[...]

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 (0.2 ” to 0.6”). A brush shorter than 5 mm must be replaced because decreased c[...]
