    5. CONSTRUCTION AND FUNCTION 5-1 CONSTRUCTION END COVER MOUNT RUBBER 5-2 FUNCTION 5-2-1 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.
  • Page 14 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.
  • Page 15 5-2-4 NO-FUSE BREAKER The no-fuse breaker protects the generator from getting damage by overloading or short circuit in the appliance. Table 5-1 shows the capacity of no-fuse breaker by each spec. and their object of protection. 5-2-5 DC CIRCUIT BREAKER The 10 ampere DC circuit breaker mounted on the control panel protects whole DC circuit from getting damage by overload or short circuit.
  • Page 16 NOTE : If your generator has receptacles pecu- liar to your country, Table 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.
  • Page 17 5-2-8 CONNECTING TO DOMESTIC CIRCUITS (HOUSE WIRING) WARNING : 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. Failure in connection may result in death, personal injury, damage to generator, damage to appli- ances, damage to the building's wiring or fire.

  • Page 19: Generator Operation

    5-3 GENERATOR OPERATION 5-3-1 GENERATION of NO-LOAD VOLTAGE (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. (2) As one or two condensers are connected to the condenser coil, the small voltage at the condenser coil generates a minute current a which flows through the condenser coil.
  • Page 20 5-3-3 FULL POWER SWITCH (Dual Voltage Type) The full power switch is provided for the dual voltage type to take out the full rated power from one receptacle in each voltage. Fig. 5-14 Fig. 5-12 Fig. 5-13 Table. 5-3 - 17 -...
  • Page 21 Two 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. Fig.

  • Page 22: Oil Sensor

    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.
  • Page 23 [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. The sensor judges that oil in the crankcase is sufficient. When oil level goes down and the inner electrode is exposed to the air due to consumption of oil, no current flow between the electrodes as air is considered to be electrically nonconductive.
  • Page 24 2 Detection circuit ... This detects quantity of oil, sufficient or not, according to difference of electric resistance across inner and outer electrodes. 3 Delay circuit ... This his prevents the sensor from making an unnecessary stop of the engine by momentary lowering of the oil level due to the engine being slanted or affected by vibration in spite of sufficient oil in the crankcase.

  • Page 25: Safety Precautions

    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. If spilt, wipe it and let dry before starting the engine. 2.

  • Page 26: Range Of Applications

    7. 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 watt- age of the appliance.
  • Page 27 (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.
  • Page 28 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 insulation, possibly burning it out.

  • Page 33: Measuring Insulation Resistance

    8-4 MEASURING INSULATION RESISTANCE 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. An insulation resistance of 1 megohm or more is nor- mal.
  • Page 34 * CONTROL PANEL Measure the insulation resistances between the live parts and the grounded parts. Fig. 8-13 Any part where the insulation resistance is less than 1MΩ has faulty insulation, and may cause electric leakage and electric shock. Replace the faulty part. - 31 -...

    9. CHECKING FUNCTIONAL MEMBERS 9-1 VOLTMETER Check the voltmeter if it is turned on by applying specific voltage. Voltmeter 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.
