PARTS LIST, PARTS DRAWINGS, AND WIRING DIAGRAM PERTAINING TO YOUR UNIT ARE ENCLOSED WITH THIS MANUAL. This manual covers the latest compact portable tractor driven Power Take Off (PTO) generator set model from Winco. This 15,000 watt generator, is designed to provide120/240V single phase electrical power for standby and utility service when commercial power interrupted, inaccessible or impractical. This PTO unit has a cast iron gear cases with a 1-3/8” – 6 spline, 540 rpm input shafts and brushless, heavy-duty 3600 rpm, 2 pole, low waveform distortion generators. This compact PTO generator units is designed to provide reliable electrical power for customers who already have a compact utility tractor with 24 to 40 horsepower and a 540 rpm PTO shaft. The PTO unit is a cost-effective way of providing needed electrical power without the cost or added maintenance of a dedicated drive engine. Primary applications for these PTOs are for infrequent or medium duty loads where the unit will normally be operated less than 50 to100 hours per year. Typical uses might be for farm, ranch or home standby or portable field power away from convenient utility or where running an extension cord is impractical. The compact PTO units are built to last, but are not intended for prime power (continuous or sole source) applications. 60706-178-6115 Page i All PTO units have a full control panel with features like large frequency meter, mainline circuit breaker, convenience and full load 4-wire receptacles. The full load matching plug is also included for customers load connection cord set. Traditional Winco power, convenience and reliability are standard features of this new series of compact PTO generators.

This manual covers standby generators driven by the power take-off of a compact tractor. This generator use a external voltage regulator excitation system. All generators are carefully inspected, tested and packaged for shipment at the factory. The generator should be unpacked as early as possible upon receipt and inspected for damage which may have occurred during shipment. Any damage noted should be promptly reported to the carrier in order that a claim can be filed to recover the cost of the damage. If at all possible, this damage should be noted on the freight bill at the time of delivery. If the damage appears to be of a major nature, the generator should not be operated until the fault has been corrected. Tractor driven generators are designed to deliver voltage and current similar to that of the normal power line. Equipment that can be operated on normal power can also be operated by the generator, provided that the capacity of the generator is not exceeded. It should be remembered that the power line, for all practical purposes, is backed by an unlimited generator. When not in use the generator should be stored in a clean dry location. All types of mechanical equipment suffer from long periods of storage without use. The generator should be used at frequent intervals to prevent deterioration and detect possible fault before an emergency condition develops. This generator set has been designed and manufactured to allow safe, reliable performance. Poor maintenance, improper or careless use can result in potential deadly hazards; from electrical shock, exhaust gas asphyxiation, or fire. Please read all safety instructions carefully before installation or use. Keep these instructions handy for future reference. Take special note and follow all warnings on the unit labels and in the manuals. ANSI SAFETY DEFINITIONS DANGER: DANGER indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. This signal word is to be limited to the most extreme situations. WARNING: WARNING indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. CAUTION: CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices. NOTE: CAUTION is also used on the unit labels and in this manual to indicate a situation that could result in serious damage or destruction of the equipment and possible personal injury. Page 1 60706-178-6115 7. INSTALLATION - Installing an isolation power transfer switch and PTO generator is not a typical “do-it-yourself” project. Consult a qualified, licensed electrician or contractor. The installation must be safe and comply with all national, state, and local codes. See page 11. a. Never operate the PTO drive generator without having it properly mounted to a concrete base or approved trailer. b. Never connect the PTO generator to an existing electrical system without installing an isolation transfer switch. c. Always insure the drive shaft is straight and level before operating the generator. GENERATOR SAFETY INFORMATION 1. ELECTRIC SHOCK - The output voltage present in this equipment can cause a fatal electric shock. This equipment must be operated by a responsible person. a. Do not allow anyone to operate the generator without proper instruction. b. Guard against electric shock. c. Avoid contact with live terminals or receptacles. d. Use extreme care if operating this unit in rain or snow. e. Use only three-prong grounded plugs and extension cords. f. Be sure the unit is properly grounded to an external ground rod driven into the earth. g. Do not make or break electrical connection under load. 2. FIRE HAZARD - Gasoline, diesel and other fuels always present a hazard of possible explosion and/or fire. a. Keep a fire extinguisher nearby and know its proper use. Fire extinguishers rated ABC by NFPA are appropriate. 3. DEADLY EXHAUST GAS - Exhaust fumes from any engine contain carbon monoxide, an invisible, odorless and deadly gas that must be mixed with fresh air. a. Operate only in well ventilated areas. b. Never operate indoors. INSTALLATION FOUNDATION MOUNTING Mount the generator on a foundation if it is to be used as a permanent or standby power source. See “TRAILER MOUNTING” if generator will be used as a portable power source (Figure 1). When planning a foundation consider the following points: 4. NOISE HAZARD - Excessive noise is not only tiring, but continual exposure can lead to loss of hearing. a. Use hearing protection equipment when working around this equipment for long periods of time. b. Keep your neighbors in mind when permanently installing this equipment. 5. CLEANLINESS - Keep the generator and surrounding clean. a. Remove all grease, ice, snow or materials that create slippery conditions around the unit. b. Remove any rags or other material that could create potential fire hazards. 6. SERVICING EQUIPMENT - All service, including the installation or replacement of service parts, should be performed only by a qualified technician. a. Use only factory approved replacement parts. b. Do not work on this equipment when fatigued. c. Use extreme caution when working on electrical components. High output voltages from this equip ment can cause serious injury or death. d. Always avoid hot mufflers, exhaust manifolds, and engine parts. They all can cause severe burns in stantly. 60706-178-6115 8. OPERATION - PTO drive shafts (tumbling bars) have many inherent dangers, extreme caution must be exercised when using them. a. NEVER allow children around a drive shaft when it is in operation. b. Keep all safety guards and shields in place and securely tightened. c. Never operate a drive shaft that has been damaged or had the safety shield removed. d. Never step over a drive shaft while it is running. e. Never wear a necktie, loose articles of clothing, or anything else that can be caught in moving parts. f. Never try to stop a turning drive shaft with your hand or your foot. A. The foundation location should enable aligning the drive shaft (tumbling bar) in a straight or nearly straight line between the power take-off and the generator input shaft. Misalignment must be less than 10 degrees during generator operation, even though the mechanical design of the tumbling bar would allow greater misalignment. B. The foundation must be solid enough to absorb generator starting and reflected load torque during operation. C. The foundation surface should be flat. D.Space is required around the generator for mounting switching devices, making connections, and for servicing. E. All four generator mounting pads must rest firmly on the foundation. Install shims if necessary to even out the foundation under the mounting pads then bolt the generator firmly in place. Page 2 TRAILER MOUNTING Mount the generator on a trailer if you plan to use it as a portable power source. See Figure 1. When selecting or building a trailer to mount the generator, consider the following points: A. The trailer construction must be strong enough to support the generator. B. The design of the trailer must enable the trailer to remain stable during operation, and to resist tipping caused by generator starting and reflected load torque. Figure 2 WARNING: Personal Injury & Equipment Damage TRAILER MAY TIP OVER AND CAUSE INJURIES IF WHEELS ARE NOT SPACED FAR ENOUGH APART. To assemble and wire the load disconnect plug, proceed as follows: 1. Strip outer jacket 2-3/4”. 2. Cut and strip leads to lengths specified for the particular plug. 3. Disassemble cable clamp and top cover. 4. Remove one blade at a time, insert the stripped end of the appropriate colored wire designated above, and tighten the set screw. 5. Fit blades through slots in bottom cover and push down until home. Please note: Make sure blades are in correct slots and oriented in accordance with the diagram above or you will not be able to close the top cover fully. 6. Place top plastic cover over assembly and partially tighten the bakalite assembly screw. Realign blades straight (so they fit into the top bakelite housing properly) and tighten the assembly screw. 7. Assemble cable clamp over the outer jacket of the wire and tighten the two clamp screws. Special Note: For small size round (less than 3/4”) and flat cables, the wire clamp may be inverted. C. The trailer height and mounting position of the generator on the trailer Figure 1 should enable aligning the drive shaft (tumbling bar) in a straight or nearly straight line between the power take-off and generator input shafts. Misalignment must be less than 10 degrees during generator operation, even though the mechanical design of the tumbling bar would allow greater misalignment. D. The generator mounting area of the trailer bed should be flat. All four generator mounting pads must rest firmly on the trailer bed. Install shims if necessary to even out the bed under the mounting pads, then bolt the generator firmly in place. Assembly The only assembly work required after unpacking the generator is to assemble and wire the load disconnect plug, which is packed in the generator carton. WARNING: Failure to wire as instructed may cause personal injury or damage to device or equipment. To be installed or checked by an electrician or qualified person only. OPERATING THE ALTERNATOR WARNING: Personal Injury When working on or around these generators, do not wear loose fitting clothing or any articles that may get caught in moving parts. WARNING: Personal Injury DISCONNECT POWER BEFORE WIRING IMPORTANT: Use copper wire only. Do not use tinned conductors. Sizing cable - see NEC 400-5. CORD SIZE: #4/4 conductor cord SO, 1.25 inch dia. max. A properly rated and installed double throw manual power isolation transfer switch must be used with a standby generator. The transfer switch isolates the load from the power line and allows you to safely operate your loads without endangering the power line repair crew. See page 11. Page 3 60706-178-6115 The load, connected to the normal terminals of the transfer switch, is energized by the normal power line when the switch is in the normal position. The generator, connected to the emergency terminals of the switch, furnishes power when the switch is in the emergency mode position. When the normal power fails, the generator is attached to the tractor by means of the power take-off shaft. WARNING: Personal Injury Be sure the safety shields are in place and retained. Start the tractor and adjust the speed until the frequency meter on the generator panel reads the proper frequency 60Hz to 61Hz. Check the connected load to assure that all heavy electrical equipment is disconnected. MAINTENANCE REQUIREMENTS 1. Maintain proper oil level in the PTO gear case. See page 5 for list of recommended vendors. Do not overfill, maintain level to the center of clear site gauge, approximately four (4) inches from the bottom of the gear case on the right side (Figure 4). CAUTION: Equipment Damage Do not overfill generator gear case. Overfilling causes overheating and oil seal failure. 2. Inspect for loose or broken wiring connections. Make sure that wiring connections are not loose at the generator end, circuit breakers, and receptacles. Move the transfer switch handle to the emergency position connecting the load to the generator. Switch on all required electrical equipment within rated capacity of the generator, then readjust tractor speed to maintain the proper frequency. 3. Do not allow dirt or chaff to collect in the interior of the generator or the ventilation openings. Inspect for indication of the entrance of mice or insects into the generator. The inlet and outlet openings are louvered, but possible damage to the louvers could occur. Mice can destroy the generator winding. NOTE: Equipment Damage If the load includes motors turn them on one at a time, highest starting current motor first, next highest second, etc. WARNING: Equipment Damage DO NOT CLEAN THE GENERATOR WHILE IT IS RUNNING. If the circuit breaker of the generator control panel trips during operation, the connected load is greater than the rated generator capacity. Reduce the load by disconnecting any nonessential equipment during emergency conditions and reset the breaker to resume power feed. When the normal commercial power is restored, for at least 15 minutes without interruption, the transfer switch can be returned to the normal position and the tractor drive generator shut down. Reduce speed gradually to minimize stress in drive line. If the generator is mounted on an offhighway trailer, such as the Winco trailer, it should be stored in a garage, barn or machine shed in a dry and clean location. The generator should be covered with a tarpaulin to prevent the entrance of dust, chaff, and/or moisture. dry elevated surface such as a board. Do not have it resting on a dirt surface. (Figure 3) CAUTION: Equipment Damage Most electrical equipment in North America operates satisfactorily at frequencies between 59 and 61 Hz (cycles per second). Operating the generator at frequencies outside that range may cause damage to the generator and/or to electrical equipment driven by the generator. OPERATION OF TRACTOR DRIVEN ALTERNATORS When the alternator is not in use, it must be maintained in a clean and dry condition. The inside of the panel, frame and air inlet and outlet must be free from dirt, chaff, and moisture (including condensation). When connection is made at the meter pole, a double throw manual isolation power transfer switch must be used. Normal power is connected to the top, the load at the center, and the alternator at the bottom of the switch. Warranty is void if an isolation transfer switch is not used (check instruction manual on transfer switch.) The generator may be stored on end, provided the generator is on a clean, 60706-178-6115 Page 4 DANGER: PERSONAL INJURY IF THE GENERATOR IS TO BE USED AS A STANDBY POWER SOURCE, A SPECIAL DISCONNECT SWITCH MUST BE INSTALLED TO SEPARATE THE GENERATOR AND THE COMMERCIAL POWER LINES. THE DISCONNECT MUST ISOLATE THE GENERATOR FROM THE COMMERCIAL POWER LINES AND THE LOAD WHEN THE GENERATOR IS ON STANDBY, AND MUST ISOLATE THE COMMERCIAL POWER LINES FROM THE LOAD AND THE GENERATOR WHEN THE GENERATOR IS SUPPLYING POWER. SEE FIGURE 6 ELECTRICAL CONNECTIONS CAUTION: Only qualified electricians should install electrical wiring. Wiring must conform to all applicable national, state, and local codes. (Reference: National Fire Protection Association Manual No. 70, National Electrical Code.) Page 5 Figure 6 60706-178-6115 PROCEDURE FOR USE 1. Set the manual transfer to mid or normal (up) position. 2. Connect the power take-off shaft securely to the alternator and the tractor. Position as near to a straight line as possible. 3. Slowly adjust power take-off up to maintain the the proper fregueny reading on the meter (60 to 61 Hz). 4. Plug 4 wire load cord set into receptacle. Place transfer switch in the emergency position. 5. Place the load circuit breaker in the “on” position. If the breaker trips, move manual transfer switch to“off” or normal position. Check for short circuit or grounded connection in the load cable to the double throw switch and repair. A breaker that trips from overload or short circuit must be reset by moving to “off” before reclosing. 6. Keep meter at the proper frequency by adjusting tractor speed. 7. The return of normal power will be indicated by the lamp on the front of transfer switch; (applicable only when the transfer switch is equipped with indicating lamps or your electrician has installed them). After sufficient time to assure that power restoration isn’t temporary, return the transfer switch to normal power (10 - 20 minutes). 8. Place the alternator circuit breaker in “off” position. Do not remove plug before opening the breaker. 9. Slowly reduce power take-off speed to a minimum and disengage the power take-off. Some tractors have a brake on the power take-off that stops the shaft instantly. Stopping the alternator rotor instantly from rated speed may result in a broken shaft or other drive line failures. 10. Exercise PTO alternator for one hour under load at least twice a year. DANGER: Personal Injury TRACTOR MUST BE SHUT OFF AND THE POWER TAKE-OFF MUST BE DISENGAGED AT THIS TIME. PTO ALIGNMENT Synchronized Unsynchronized Position the alternator in such a manner that the power take-off shaft is as near to direct line in all directions as possible. This will increase the life of the power take-off shaft, reduce light flicker, reduce wear on bearings of both the power take-off and the alternator, and reduce vibration. The maximum angle from a straight line should not exceed 10°. For a power take-off shaft length of 42 inches, 10° is approximately 7 inch misalignment. For extended distance the maximum misalignment would increase 2 inches for each foot. For example: For a 4 foot PTO shaft, the maximum misalignment is 8 inches from a straight line. Figure 5 LUBRICATION 1. Check the generator gear case oil level before each use of the generator. See Figure 4. Maintain the oil level before each use of the generator. Maintain the oil level at oil level plug height. The generator is shipped with lubricant in the gear case. Specifications for gear case lubricant are: API Service: GL-5 EP Rated, Grade: SAE 85W-90-140, Amount: 1 pint The following kinds of oil are recommended for use in the generator gear case: Mobil SAE 85W90-140 API Service GL-5 Sunoco/DX XL80W90-140 Kendal Three Star 85W-140 Amoco 85W140 or equivalent 2. The generator bearings are factory lubricated and sealed, and require no further lubrication. 3. The splined generator input shaft should be cleaned and lubricated with a thin film of grease before and after each use of the generator. See Figure 6 for lubrication schedule. 4. The drive shaft (tumbling bar) requires greasing. Keep the universal joints in the coupling shaft free from grease and dirt buildup. See Figure 6 for lubrication schedule. NOTE: Do not over lubricate the universal joints. Figure 6 60706-178-6115 Page 6 NOTE: THE FOLLOWING INFORMATION IS FOR REFERENCE ONLY - CONSULT A QUALIFIED SERVICE PERSON FOR FURTHER TESTING AND REPAIR. Testing of Rectifiers Unbolt the rectifier diode stud from the mounting clamp. Move rectifier away from the metal stud. 1. Connect black lead of meter to stud of rectifier and red lead to the solder terminal. Meter should read a low resistance. bending occurs closer than 1/8 inch to the rectifier body, and that header seals are not fractured or broken. If this seal is broken, it removes mechanical support for the lead and allows entry of moisture into the rectifier, almost assuring early failure. 2. Now, reverse the lead on rectifier terminals. Meter should read open circuit of infinite resis tance. A shorted diode will give low resistance reading in both directions. An open diode will give a high resistance (infinite) reading in both directions. 4. Care must be taken during all soldering operations. It is unsafe to exceed the general specification to which diodes are tested for solder ability. This is 10 +/- 2 seconds at a temperature of 230°C + 5°C at a point 1/16 +/- 1/32 inch from the diode body. This is not as restrictive as it may sound, since 230°C is 446°F and 60/40 solder melts at 375°F, and with proper procedure and soldering tools a solder joint can be made in 4 to 7 seconds. Also, solder joints are almost never made this close to the diode body. Heat sinks, such as a pair of needle nose pliers or alligator clips, can be attached to the lead between the solder joint and the diode body to further reduce the possibility of heat damage. Handling Procedures for Rectifier Diodes 1. Rectifier diodes should be handled in a manner which avoids the possibility of sudden shocks being applied, such as those encountered in dropping from a work bench to a hard floor. Damage done to the rectifier by such shocks may not be detected by subsequent testing, yet may cause poor system reliability. 2. Any lead trimming or forming operations should be done with care to avoid damaging the leads or the glass header seals. 3. Leads should never be bent or twisted. If lead forming is necessary the lead should be supported so that no Testing Stator 1. Instrument required - Volt-Ohmmeter. Set on Ohm X1 scale. 2. Check Ohmmeter by touching leads together. Reading should be zero. 3. Tag and lift control wires from stator winding(s) to be checked. 4. First, check if stator winding(s) are grounded a. Connect one lead of Ohmmeter to ground. b. Touch other lead to each stator wire. Meter should stay at infinite (not move). c. If reading is indicated, stator is grounded and should be replaced. d. Check all three windings. Also, precautions should be taken to prevent solder or flux bridging which causes a conductive path across the case of the rectifiers. As a precaution all flux should be removed by using alcohol and a small brush. Pay particular attention to assure that glass header seals are free of all flux. Stator - 6 Wires - 3 Windings 1 Phase This armature has two power windings and one excitation (auxiliary) winding. 1. Connect ohmmeter one lead to T1-red. Other lead to T2-green. Meter should read near zero. Then other lead to T3-black. Meter should read infinite. Then other lead to Z1-white. Meter should read infinite. 2. Connect one lead to T3-black. Other lead to T4-yellow Meter should read near zero. Then other lead to Z1-white. Meter should read infinite. 3. Connect one lead to Z1-white. Other lead to Z2-brown Meter should read near zero 5. Second, check stator windings for opens. Symptom: when generator was running, no voltage on one line to neutral.
