SAFE OPERATION Cautious operation is your best insurance against an accident. Read and understand this section carefully before operating the engine. All operators, no matter how knowledgeable they may be, should read this and other related manuals before operating the engine or any equipment attached to it. It is the owner’s responsibility to instruct all operators in safe operation.
Page 7
KEEP AREA AROUND THE ENGINE CLEAN • Be sure to stop the engine before cleaning. • Keep the engine clean and free of accumulated dirt, grease and trash. • DO NOT stop the engine without idling; Temperatures around the engine rises suddenly. Keep the engine idling for about 5 minutes before stopping.
Page 8
ESCAPING FLUIDS • Relieve all pressure in the air, oil and cooling systems before any lines, fittings or related items are removed or disconnected. • Be alert for possible pressure release when disconnecting any device from a system that is pressurized. DO NOT check for pressure leaks with your hands.
Page 9
ANTI-FREEZE AND DISPOSAL OF FLUIDS • Anti-freeze contains toxic chemicals. Wear rubber gloves when handling anti-freeze. In case of contact with skin, wash immediately to avoid personal injury. • DO NOT mix different types of Anti-freeze. The mixture can produce a chemical reaction resulting in the formation of harmful substances.
PRE-OPERATION CHECK ENGINE BREAK-IN PERIOD During the engine break-in period, observe the following recommendations: Change the engine oil and oil filter cartridge after the first 50 hours of operation. (See “ENGINE OIL” in ENGINE MAINTENANCE SERVICE SCHEDULE). In ambient temperature above 32°F (0°C) approximately 3-5 minutes without a load is sufficient for engine warm up.
OPERATING THE ENGINE ENGINE STARTING CONTROLS 1) Generator Main Switch must be in the ON position. 2) Hold Start/Stop Switch for 1 second and release. 3) Glow Plugs will preheat for 8 seconds. LED flashes slowly. 4) Preheating will cease during engine cranking cycle. LED continues flashing. 5) Engine begins an 8 seconds crank cycle, After 4 seconds of cranking the PT-ECU-63 will check for an AC signal from the generator.

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.
Page 23
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.

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.
Page 37
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.
3. Add oil to crankcase, to the dipstick FULL mark. 4. Connect fuel lines, remote switch, load leads and battery terminals. (Consult the Specification Charts on the Following Pages for Requirements) MODEL PTSMH-15 PTSMH-17.5 PTSMH-20 GENERATOR DIMENSIONS L x W x H 46.5”...

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.

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.
Page 45
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.
Page 46
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.
Page 48
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.
Page 49
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.
Page 50
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.
Page 51
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.

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.

Power Controller Module (PCM) And Display (PCMD)
Feature Summary The PowerTech PCM controls all of the start and run processes and characteristics of any PowerTech generator. The features of the application are: Internal Ambient Temperature Sensor Provides an on-board temperature sensor. Oil Pressure Sensor / Switch Input Allows input from an external oil pressure sensor or switch.
Page 65
Operating Behavior Starting The generator starts in response to the “START” button being depressed for 1 second. The PCM goes into the Pre-Heat State, followed by the Cranking State, then finally, the Running State. The PCM attempts to start the generator a specific number of times (configuration parameter) before declaring a Fault.
Page 66
Automatic Generator Start (AGS) The Automatic Generator Start (AGS) allows the generator to start based upon the battery level. The trigger voltage is configurable via a configuration parameter. The entire feature can be enabled/disabled by a configuration parameter. The AGS feature is currently disabled, by default. Safety Monitoring And Shutdown The PCM monitors inputs for safety limitations which might damage the generator.
