Tractor Drive PTO Generators OWNERS MANUAL INSTALLATION AND OPERATION INSTRUCTIONS 12PTOC-3 25PTOC-3 SAFETY FIRST READ THIS MANUAL BEFORE OPERATING YOUR GENERATOR.
Read and understand all instructions in this manual before starting and operating the generator set. USING THIS MANUAL Congratulations on your choice of a Winco generator set. You have selected a high-quality, precision-engineered generator set designed and tested to give you years of satisfactory standby service. To get the best performance from your new generator set, it is important that you carefully read and follow the operating instructions in this manual.
. SAFETY INFORMATION 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. a. b. 4. b. 5. b. d.
Description The WINCO rotating armature power take-off generators are designed primarily for farm use as a standby electrical power supply, utilizing the power take-off of a tractor or truck as the prime mover. This PTO drive generator will provide, 120/240V single phase, 60Hz electrical service when properly driven. NOTE: The prime mover which drives the generator must be capable of delivering approximately 2 HP per 1000 watts output from the generator. Observe input RPM specifications.
. Insert the brass pin (with cable) into the plug body, and line up the retainer pin holes in the brass pin with those in the plug body. 6. Insert the retainer pin, and tap it firmly into place. The retainer pin will protrude approximately 3/8" when fully seated. (See Figure 1.) 7. Repeat steps 4 through 6 for each brass pin. Make sure to connect the neutral lead (cable), identified and color coded in conformance with the applicable local electrical codes, to the large diameter pin (“N”) on the plug. C.
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.) DANGER: PERSONAL INJURY POWER SOURCE, A SPECIAL DISCONNECT SWITCH MUST BE INSTALLED TO SEPARATE THE GENERATOR AND THE COMMERCIAL POWER LINES.
MOTOR LOAD Motor Amps Horsepower Operation OUTPUT POWER AVAILABLE AND LOAD DETERMINATION Before using the generator, read and understand the following information. Generator output current (amperage) is internally limited by circuit breakers. If too much demand is placed on a generator output (if you try to drive too many motors with it, for example), one of the circuit breakers will trip, cutting off the output in order to protect the generator.
7. Check all electrical connections in the system to be energized by the generator. Make sure the connections are correct and are tight. 8. Make sure all loads are turned off. Do not start the generator under load. GENERATOR STARTING PROCEDURE 1. With the power take-off drive disengaged, start the engine which will drive the generator. Run the engine long enough to warm it up before proceeding, so that it will run smoothly and achieve full power under generator load. Figure 6 2.
MAINTENANCE universal joints in the coupling shaft free from grease and dirt buildup. General Information NOTE: Do not over lubricate the universal joints. The main components of the generator are: armature, field coils, cooling fan, brushes, brush holder assembly, end brackets, rectifier and voltage regulator. Before performing any maintenance on the generator, isolate and/or disable the drive system so the unit can not be accidentally started while being repaired.
Proceed as follows: 1. Remove control box cover. Vacuum or blow dust or debris from the control box. Inspect all wiring for correct routing, fraying insulation, and secure connections. 2. Remove end cover. Vacuum or blow dust and debris from the inside of the generator. Inspect wiring for loose connections, fraying insulation and correct wire routing. 3. Replace end cover and control box cover. GENERATOR STORAGE Before storing the generator, apply a heavy coat of grease to the splined input shaft.
3. Open Test. Set meter to read low resistance (R x ohms). Holding one meter lead on surface of slip ring No. 1, touch other meter lead to surface of slip ring No. 2 while observing the meter. Meter should indicate continuity (low resistance - less than one ohm is typical). If the meter indicates open circuit (infinite resistance) part of armature winding is open. This may be caused by a repairable defect in the connection at the slip ring, however generally an open armature will have to be replaced.
TROUBLE SHOOTING TABLE SYMPTOM CAUSE(S) No output voltage. 1. Circuit breaker open. 2. Defective voltmeter. 3. Short circuit in the load. 1. 2. 3. 4. Defective receptacles. 4. Loose (or broken) wires or connections in control box. 6. Defective rectifier. 5. 7. Dirty slip rings. 7. 8. Brushes binding in holders. 8. 9. Shorted or open armature. 9. 10. Shorted or open field coils. 10. 5. Low voltage. High voltage. CORRECTIVE ACTION 6. Reset circuit breakers, replace if defective.
