GENERATOR ASSEMBLY INFORMATION EXCITER TYPE GENERATOR The exciter pole pieces contain residual magnetism, which sets up lines of force across the air gap to the exciter armature. When the exciter begins to rotate a voltage is induced and current flow is initiated in the exciter armature AC windings. This voltage is fed to the rotating rectifier assembly, rectified and fed to the alternator field, which sets up lines of force across the air gap to the alternator stator windings and to the output circuit.
ROTATING FIELD ASSEMBLY (ROTOR) The rotating field assembly consists basically of four members: 1) the shaft assembly, 2) the core assembly, 3) the field coil damper windings, and 4) balance lugs to provide a high degree of static and dynamic balance. CORE ASSEMBLY The core assembly consists of a quantity of thin steel plates compressed and fastened together to form a single laminated assembly. The field windings are wound around this assembly.

SAFTEY PRECAUTIONS A generator set can be potentially dangerous if not properly maintained and operated. The best Safe Guard against a dangerous situation is education, good judgment and common sense. For safe trouble free operation of your generator set some general precautions are listed below. Be sure to read, understand and follow these precautions. Please call Power Technology Southeast, Inc. with any concerns you may have with your generator set.
7) EXPLOSION: Never connect the negative (-) battery cable to the positive (+) connection terminal of the starter solenoid, or test the battery by shorting terminals together. This could ignite fuel vapors or cause the battery to explode. To disconnect the battery remove the negative battery cable first and reconnect it last. Do not modify the fuel tank or propulsion engine fuel system. Your vehicle must be equipped with a fuel pick-up arrangement as described in the Fuel System section of this manual.
GENERATOR INSTALLATION In RECREATIONAL VEHICLES INTRODUCTION Use this section as a guide when installing a generator set in a recreational vehicle, and then refer to the appropriate operation section for specific instructions. When installing a RV generator set the installation must comply with the current Safety Standards of ANSI / RVIA EGS-1-2003, ANSI A 119.2 / NFPA 501C and applicable articles of ANSI / NFPA 70 of the National Electrical Code.

GENERATOR COMPARTMENT SIZE In planning the size of the generator compartment allow for the minimum clearance of one (1) inch necessary to adequately cool the generator set. The thickness of insulation and sound deadening material used to line the compartment must be taken into consideration when planning this clearance. To maintain minimum clearance it may be necessary to enlarge the compartment.

GENERATOR ENCLOSURES Some installations require the Genset to be mounted inside an enclosure. Enclosures are generally constructed of heavy gauge sheet metal, and completely insulated. Enclosures are typically installed in RV’s with large unobstructed compartments. The major advantage to installing a Genset in an enclosure is to achieve a significant reduction in the unit’s sound level. In order to maintain the ambient temperature within the enclosure a forced cool air system is generally employed.

SYSTEMS CONNECTION REMOTE RADIATOR COOLING SYSTEM Use the following data in designing and installing the generator set cooling system. To insure a safe effective installation, be sure the cooling system selected follows these parameters. Power Technology offers radiator assemblies, which meet these requirements and will adequately cool the generator. Select the radiator assembly best suited for the generator installation.
SYSTEMS CONNECTION FUEL SYSTEM The diesel fuel system for the generator set must be designed to operate independently from the vehicles main engine if both engines are to be operated at the same time. The best way to do this is to have separate fuel tanks, but this is usually impractical because of space restrictions. In most installations both engines operate from a common fuel tank with separate pick-up tubes for each engine, not a Tee fitting arrangement.
EXHAUST SYSTEM IMPORTANT SAFETY TIPS: When exhaust system components are not furnished by Power Technology as part of the Genset, the installer is responsible for meeting the following requirements. 1) Only use exhaust system components, which do not restrict exhaust flow. A restricted exhaust system will create excessive backpressure and may cause poor engine performance and possible engine damage. The maximum allowable backpressure for the engines listed in this manual is 1.57in Hg, (40mmHg).

ELECTRICAL CONNECTIONS ELECTRICAL WIRING All wiring must be applicable with local electrical codes. A qualified licensed electrician must perform all electrical wiring connections. Ground Fault (GFCI) breakers must be installed to protect all vehicle branch circuits. All switches and controls must be securely mounted to prevent damage and accidental opening or closing from vibration, road shock and vehicle motion.
MOTOR LOADS When figuring generator set capacity requirements for installation involving motor loads, do not overlook the high current demanded by the motor during start-up. The “In-Rush” of starting current may be 2 to 5 times higher than that required when the motor reaches normal operating speed. Reserve capacity must be allowed for in rush demands plus other loads, which could be on the line as the motor starts.
APPLIANCE LOADS Generator sets in recreational vehicles are often used to supply AC voltage for appliances. With the exception of a resistance-type load such as a water heater, requirements for appliances are usually low. However, such loads must not be overlooked when calculating the total wattage requirements. To avoid an overload situation, reserve capacity should also be calculated for unanticipated appliance loads.
GAC ESD2110 SERIES SPEED CONTROL UNIT The ESD2110 Speed Control Unit is part of an engine governing system designed to control engine speed and stability throughout the load range. Operating in combination with a magnetic pick-up and electric actuator the ESD2110 will maintain the proper engine speed by adjusting the fueling system according to the applied load. By maintaining a set engine speed the generator voltage output and frequency will remain constant and stable.
BASLER AVC63-4 ANALOG VOLTAGE CONTROLLER The AVC63-4 voltage regulator is designed for use on 50/60 Hz brushless generators. Features include frequency compensation, over excitation shutdown, a solid-state build-up circuit and EMI filtering. The AVC63-4 attaches to the generator with spade type wire terminals for a secure connection. The AVC63-4 has three adjustable potentiometers for fine-tuning the output voltage, stability and under frequency.
