CONSTRUCTION AND FUNCTION 5-1 CONSTRUCTION 5-2 FUNCTION 5-2-1 ST A TOR 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.
- 11 - 5-2-2 CONDENSER One or two condensers are installed in the con- trol box and are connected to the condenser coil of the stator . These condensers and condenser coil regulate the output voltage. 5-2-3 ROTOR The rotor consists of a laminated silicon steel sheet core and a field coil which is wound over the core.
- 12 - 5-2-4 NO-FUSE BREAKER The no-fuse breaker protects the generator from getting damage by overloading or short circuit in the appliance. T able 5-1 shows the capacity of no-fuse breaker by each spec.
- 13 - NOTE : If your generator has receptacles pecu- liar to your country , T able 5-2 does not apply . 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.
- 14 - 5-2-8 CONNECTING TO DOMESTIC CIRCUITS (HOUSE WIRING) W ARNING : All Robin generators are a neutral ungrounded type. If a generator is to be connected to residential or commercial power lines, such as a stand-by power source during power outage, all connections must be made by a licensed electrician.

- 16 - 5-3 GENERA T OR OPERA TION 5-3-1 GENERA TION of NO-LOAD VOL T AGE (1) When the generator starts running, the permanent magnet built-in to the rotor generates 3 to 6V of AC voltage in the main coil and condenser coil wound on the stator .
- 17 - 5-3-3 FULL POWER SWITCH (Dual V oltage T ype) The full power switch is provided for the dual voltage type to take out the full rated power from one receptacle in each voltage.
- 18 - T wo main coils are wound over stator core. Each main coil outputs half the rated power at the lower voltage (120V). These main coils are wound to be in the same phase. The full power switch reconnects these main coils in parallel or in series.
- 19 - 5-4 OIL SENSOR 5-4-1 DESCRIPTION * The oil sensor mainly functions to detect posi- tion of the surface of engine oil in the crankcase of engines for general use and to stop the en- gine automatically when the oil level goes down below the lower limit specified.
- 20 - [Judgement of oil level] When sufficient oil is in the crankcase, both of inner and outer electrodes are immersed in the oil through which current flows across the electrodes.
- 21 - 2 Detection circuit ..... This detects quantity of oil, sufficient or not, according to dif ference of electric resistance across inner and outer electrodes.
- 22 - 6. 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.
- 23 - 7. RANGE OF APPLICA TIONS 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 watt- age of the appliance.
- 24 - (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 .
- 25 - 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).
- 26 - 8. MEASURING PROCEDURES 8-1 MEASURING INSTRUMENTS 8-1-1 “Dr . ROBIN” GENERA TOR TESTER The “Dr . Robin” generator tester is exclusively designed for fast, easy diagnosis and repair of Robin generators.
- 27 - 8-1-2 INSTRUMENTS (1) VOL TMETER 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 150V : T ype wit.
- 28 - (4) CIRCUIT TESTER Used for measuring resistance, etc. (5) MEGGER TESTER Used for measuring generator insulation re- sistance. Select one with testing voltage range of 500V . (6) T ACHOMETER Use the contactless type tacho meter . Fig. 8 -5 Fig.
- 29 - 8-2 AC OUTPUT MEASURING Use a circuit like the shown in Fig.8-8 for measuring AC output. A hot plate or lamp with a power factor of 1.0 may be used as a load. Adjust the load and rpm. and check that the voltage range is as specified in T able 8-2 at the rated amperage and rated rpm.
- 30 - 8-4 MEASURING INSULA TION RESIST ANCE Use a “Dr . Robin” generator tester in megger tester mode or use a megger tester to check the insula- tion resistance. Connect a megger tester to one of receptacle output terminals and the ground ter- minal, then measure the insulation resistance.
- 31 - * CONTROL P ANEL Measure the insulation resistances between the live parts and the grounded parts. Any part where the insulation resistance is less than 1M Ω has faulty insulation, and may cause electric leakage and electric shock. Replace the faulty part.
- 32 - 9. CHECKING FUNCTIONAL MEMBERS 9-1 VOL TMETER Check the voltmeter if it is turned on by applying specific voltage. V oltmeter cannot be checked with circuit tester because its resistance is too large. 1 Check that no disconnection nor short-circuit occurs with a tester , and the internal resistance is around 00k ohms normally .
- 33 - 9-4 ST A T OR Disengage connectors on the wires from stator and check the resistance between wires with a “Dr . Robin” or a circuit tester referring to the fol- lowing table. NOTE : If the circuit tester is not sufficiently accurate, it may not show the values given and may give erroneous readings.
- 34 - 9-5 ROTOR ASSEMBL Y (1) Using a “Dr . Robin” or a circuit tester , measure the resistance of the field coil at the terminals. NOTE 1 : Because a diode is soldered to the coil ends at the terminals, resistance may be measured only when tester probes touche the terminals in one combination of polarity .
- 35 - * If such an instrument is unavailable, the condenser can be checked by replacing with a new one. If the generator performs good with new condenser , the cause of trouble is defect in original condenser . 9-7 DIODE RECTIFIER Circuit inside of the diode rectifiers is as shown in Fig.
- 36 - * Checking table for digital circuit tester . NOTE 1 : Because of the difference of measuring method between the analogue circuit tester and the digital circuit tester , polarity of tester needles should be reversed.
- 37 - 10. DISASSEMBL Y AND ASSEMBL Y 10-1 PREP ARA TION and PRECAUTIONS 1) Be sure to memorize the location of individual parts when disassembling the generator so that the generator can be reassembled correctly . T ag the disassembled part with the necessary information to facilitate easier and smoother reassembly .
