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. 3.
DESCRIPTION The WINCO PTO drive generator will provide, depending on the unit purchased, 120/240V single phase, 120/240V three phase, 120/208 three phase or 277/480 three phase 60Hz electrical service when direct-driven. Tractor or vehicle power take-off shafts, can be used for driving these generators. 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.
The following wire sizes are recommended for each unit. Generator Model W85PTOS W100PTOS W105PTOT W135PTOS W145PTOT W150PTOS W165PTOT Size AWG 4/0 4/0 4/0 350MCM 4/0 500MCM 1/0 Insulation Neoprene/THHN Neoprene/THHN Neoprene/THHN THHN NO THHN NO THHN NO THHN NO Plug Plug Plug Plug 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.
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. ELECTRICAL CONNECTIONS CAUTION: Only qualified electricians should install electrical wiring. Figure 5 3117-30 Wiring must conform to all applicable national, state, and local codes. (Reference: National Fire Protection Association Manual No.
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 5. 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 three circuit breakers.
6. Make sure that the electrical loads to be powered by the generator will not exceed the current ratings of the generator, receptacle, or cord set which will supply the current. 7. Check all electrical connections in the system to be energized by the generator. Make sure the connections are correct and tight and the load disconnect plug (if provided) is fully seated in the receptacle. 8. Make sure all loads are turned off. Do not start the generator under load. GENERATOR STARTING PROCEDURE 1.
NOTE: Do not over lubricate the universal joints. 5. Shut off the engine. 4. Disconnect drive shaft (tumbling bar) power take-off end first, then generator end. See Figure 8 for recommended lubrication schedule for the coupling shaft. MAINTENANCE The following chart lists various symptoms of poor generator operation with possible causes for them and the appropriate corrective action. You will need a volt-ohm meter or test light to check some of the causes.
2. Remove cooling fan shroud. Vacuum or blow dust from screen and fan blades. Wipe them off with cleaning solvent if necessary. 5. Replace the oil level check plug. 6. Replace the breather. 3. Vacuum or blow dust and other debris from inside generator and control box. CLEANING & INSPECTING THE GENERATOR Use a vacuum cleaner or dry low pressure compressed air (regulated at 25-35 PSI) to clean the generator periodically. 4.
SYMPTOM CAUSE(S) CORRECTIVE ACTION High voltage. 1. Defective or misadjusted AVR 1. Adjust, repair or replace as required. Output voltage flickering or fluctuation. 1. Tumbling bar (coupling shaft) misalignment. Engine speed not constant. 1. Reduce tumbling bar misalignment to less than 15 degrees. 2. 3. 4. Loose connection in field circuit. Tumbling bar U-joints not synchronized. 3. 4. Engine governor may be worn or improperly adjusted. Set or repair defective governor.
