    In addition, the EF3000iSE is packed full of convenient design features throughout, such as large fuel tank filling mouth, outstanding easy starting. The EF3000iSE is also a model that can be used for a wide range of applications, even able to supply sine wave AC current to a UPS, Uninterruptible Power Supply.
  • Page 5: Control Unit

    High temperature Control unit Inverter system of EF3000iSE In the EF3000iSE, the control unit and multi-pole alternator cooperate to generate AC output. The inverter, controlled by a 16-bit microcomputer, is a PWM sine wave inverter. * PWM: Pulse Width Modulation 1.
  • Page 6: Electronic Governor

    Power generation Stage 1. The rectifier circuit converts three-phase AC into DC and it maintains stable DC voltage using a con- stant voltage circuit Stage 2. The Constant voltage DC current is stored in a condenser. Stage 3. The PWM, pulse width modulator, inverter circuit generates a stable sine wave AC current. Stage 4.

    ON. Continuous running time EF3000iSE is able to run for 20.5 hours with 1/4 load with fuel tank full, when economy control switch is on. With rated load: 8.0 hours With 1/4 load: 20.5 hours...
  • Page 9: Frequency Variation

    Therefore, an inverter generator provides constant AC output frequency even if the load changes which is equivalent quality to the commercial power supplies. The frequency variation of EF3000iSE is less than 0.1 %. Voltage variation The output voltage with no load is approximately 10 %...
  • Page 10: Electronic Breaker

    It takes some duration to compensate the voltage from the momentary voltage drop by revving up the engine. This duration is called settling time. In case of an EF3000iSE, the settling time is shorter than 2 seconds, when a maximum rated load is turned on.

  • Page 15: Battery Charging

    Battery charging I Conditions of use of the DC power supply (exclusively for charging 12V battery) The DC power supply is designed to charge a battery of 40AH which is half discharged. 12V battery The time taken to charge a battery depends on how the battery is discharged. Charging is complete when the specific gravity of the battery is 1.26-1.28.

    I Handling precautions If you continue to charge the battery for many hours, the temperature of the electrolyte will rise and battery performance may deteriorate. Handling procedures vary with the type of battery. 1. Remove the cords and tubes from the battery and then remove the battery. 2.
  • Page 17 Introduction of Power Boost Technology EF3000iSEB is equipped with a DC-DC converter, which supplies supplemental electric current to the invert- er control unit to boost up the generator output for maximum 10 seconds. Control Unit DC-DC converter (Power Boost Technology) DC-DC converter is an electrical device to step up DC voltage.
  • Page 18 * Overload indicator lamp : The DC-DC converter is turned on automatically, when the generator output exceeds over 180 % of its rated load to boost generator output to assist the starting cur- rent of the load, such as an air conditioner. When the DC-DC converter is turned on automatically, the generator is obviously overloaded, thus the overload indicator lamp blinks quickly with 0.5-second interval...

  • Page 20: Ignition System

    Ignition system Ignition coil & TCI TCI ignition system is equipped with a speed limiter function. Speed limiter: 4500 rpm The ignition coil and TCI unit is a single built-in unit, while the speed limiter unit is a separate component installed in the control box.
  • Page 21: Auto De-Compressor System

    Auto-decompression system This engine is equipped with auto-decompression sys- tem to facilitate engine starting operation. While the engine is stationary or running at very low speed, a pin provided in the camshaft is projected above the base circle of exhaust cam lobe. The pin, consequently, pushes valve lifter causing exhaust valve to stay open, thus the compression pres- sure is released.
  • Page 22 Transportation Please observe the following warnings when transporting the generator in a car, truck or other vehicle. Q WARNING: 9 Since there is the risk of fuel (gasoline) spilling from the fuel tank due to vibrations and impacts dur- ing transport, do not transport the generator with fuel in the fuel tank. 9 Since there is the risk of fuel (gasoline) vaporizing and igniting, do not allow the car or truck to stand for a long period of time in locations subject to direct sunlight with the generator inside the vehicle.
  • Page 23 NOTE: The proper disposal of oil-based waste liquids is mandated by law (Pollution Control Ordinance). Please con- sult your Yamaha dealer. 1. Warm up the engine for a few minutes. 2. Turn the engine switch to the “STOP” position to stop the engine.
