GENERATOR ASSEMBLY INFORMATION BRUSH and EXCITER TYPE GENERATOR BRUSH TYPE Brush Type generators use a set of carbon or graphite brushes that are set into a spring loaded brush holder, which house and support the brushes. This brush holder is mounted in such a way as to allow the brushes to maintain a sliding electrical contact between the stationary and rotating components of the generator.
FIELD COIL VOLTAGE SOURCE (EXCITER TYPE ONLY) Field coil DC voltage is obtained by rectifying the voltage from the phase to neutral line of the generator output, or either appropriate terminal to provide the needed voltage reference. The rectifier bridge is an internal part of the static regulator. The static regulator senses a change in the generator output and automatically regulates current flow in the exciter field coil circuit to increase or decrease the exciter field strength.

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. The installation of a RV generator set shall comply with current standards of ANSI / RVIA EGS-1, NFPA 1192 / ANSI A 119.2, ANSI / NFPA 70, NFPA 551 and applicable articles of the National Electrical Code. Generator set installations must also comply with state and local requirements.

GENERATOR COMPARTMENT SIZE In planning the size of the generator compartment or bay allow for the minimum clearance 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. The generator set must be securely fastened to avoid unwanted movement from vibration and road shock.

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.

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.
ES52F ENGINE CONTROLLER The ES52F Engine Controller is designed to enable automatic Start/Stop capability as well as providing fault protection for the generator. The ES52F will automatically Start the generator upon command and will monitor vital engine and generator functions. In the event a failure was to occur, the ES52F will automatically Stop the engine thus preventing further problems.
TROUBLESHOOTING Trouble Possible Cause Suggested Action Unit does not operate when powered to test mode Power leads to unit are reversed. Bad ground connection from engine to controller unit. Battery is low or terminals are dirty. Crank circuitry wiring improperly connected. Bad ground connection from engine to controller. Crank relay damaged. Or on board fuse is blown. Confirm correct wiring for ground And bat, and re-attempt testing.
