Anleitung Zusammenfassung


Each single winding can supply a 120-volt, 60-Hertz AC output. 4 Generac® Power Systems, Inc. When the two windings are connected in series, a 240volt, 60-Hertz AC output results. Typically, the two “hot” leads in the circuit are Wires 11 and 44. The neutral leads are the junction of Wires 22 and 33. Figure 1.1 – Single-phase Generator AC Connection System Neutral Block 1.4 PREPACKAGED TRANSFER SWITCH The transfer switch shipped with this generator is rated 200 amps maximum at 120/240 volts AC single-phase. The enclosure of the transfer switch is NEMA 3R. This type of enclosure is intended for indoor or outdoor use. Follow these rules: • Install the transfer switch on a firm, sturdy supporting structure. • To prevent switch distortion, level the switch if necessary. This can be done by placing washers between the switch enclosure and mounting surface. • Never install the switch where any corrosive substance might drop onto the enclosure. • Where practical, protect the switch against excessive moisture, dust, dirt, lint, and construction grit. Always prevent corrosive vapors from coming in contact with enclosure. 1.5 AUTOMATIC SYSTEM OPERATION When this generator, along with its transfer switch, has been installed and interconnected, a circuit board in the generator panel continuously monitors utility power source voltage. Should that voltage drop below a preset value, and remain at such a low state for a preset amount of time, the generator cranks and starts. After the generator starts, the transfer switch transfers load circuits so the generator can power them. When utility source voltage has been restored, the switch transfers back to the utility source voltage, and the generator then shuts down after a brief cool-down time. 1.6 MAIN CIRCUIT BREAKER The generator’s main circuit breaker is included with the unit as shipped from the factory. The breaker for each unit is described as follows: 1.7 ENGINE PROTECTIVE DEVICES The engine has several safety switches that cause it to automatically shut down under the following conditions: low oil pressure, high coolant temperature, low coolant level, engine overspeed and overcrank. 1.7.1 LOW OIL PRESSURE SWITCH This switch is normally closed (N.C.) but is held open by engine oil pressure during engine running. Should operating oil pressure drop below approximately 10 psi (68 kPa), the switch contacts close, and the engine shuts down automatically (Figure 1.2). Figure 1.2 – Engine Protective Devices 1.7.2 HIGH COOLANT TEMPERATURE SWITCH This normally open (N.O.) thermostatic switch has a sensing tip that is immersed in captive coolant. Should the coolant temperature exceed approximately 121° C (250° F), the switch contacts close, which causes the engine to shut down automatically (Figure 1.2). 1.7.3 LOW COOLANT LEVEL SWITCH Should the engine coolant level drop below the level of the high coolant temperature switch, it is possible for the engine to overheat without automatic shut down. To prevent such overheating without automatic shut down, the engine has a low coolant level sensor. If the engine coolant drops too low, the engine automatically shuts down (Figure 1.2). 1.7.4 OVERSPEED SHUTDOWN The control module assembly (CMA) circuit board on liquid-cooled units receives AC frequency (rpm) signals directly from the stator AC power windings. Should AC frequency exceed approximately 72 Hertz, circuit board action will automatically shut down the engine. 1.7.5 OVERCRANK SHUTDOWN After 90 seconds of crank-rest cycles (about seven seconds cranking/seven seconds at rest), this function ends cranking if the engine fails to start in that 90-second span. 1.7.6 DC FUSE This fuse is located on the front panel of the control system. It protects the panel wiring and components from damaging overload. Always remove this fuse before commencing work on the generator. The unit will not start or crank if the fuse is blown. Replace the fuse with one of the same size, type, and rating. Generac uses an AGC fuse rated at 15 amps. 1.8 SPECIFICATIONS 1.8.1 GENERATOR Models..............................0043733, 0043734,, 0043735 0046262, 0046263, 0046264 Rated Maximum Continuous AC Power Output (kW)*..................................................40 Rated Voltage (volts) ................................................120/240 Rated Maximum Continuous Current at 240 Volts, Single-phase (amps)................................167 Number of Rotor Poles ........................................................4 Driven Speed of Rotor (rpm) ........................................1,800 Type of Stator ........................................................Four-wire Rotor Excitation System ..................................Direct Excited Brush-type System Stator Insulation ....................................................Class “H” Rotor Insulation ......................................................Class “F” *Rated power of generator is subject to and limited by such factors as ambient tempera...
