SAVE THESE INSTRUCTIONS This manual contains important instructions that should be followed during installation and maintenance of the generator. Read and understand all instructions in the manual before starting and operating the generator set. USING THE 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 service.
SAFETY INFORMATION This engine 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, 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.
TESTING POLICY Before any generator is shipped from the factory, it is fully checked for performance. The generator is loaded to its full capacity, and the voltage, current and frequency are carefully checked. Rated output of generator is based on engineering tests of typical units, and is subject to, and limited by, the temperature, altitude, fuel, and other conditions specified by the manufacturer of the applicable engines.
PREPARING THE UNIT produces more power at higher speeds, less when slowed. The prime mover must be run fast enough to reach the desired horsepower for good generator operation. UNPACKING CAUTION: EQUIPMENT DAMAGE The drive belt system must be of adequate size and must be tight enough to power the generator without slippage. Be careful not to overtighten to the extent that it puts excessive strain on the bearings. Doing so can cause bearing failure and other possible damage to the generator.
The normal slight variations in speed also directly affect the frequency of the output current. This frequency variation has no appreciable effect in the operation of most loads (such as motors, lights and most small appliances). However, timing devices and clocks will not keep perfect time unless the engine can keep the generator running at exactly 3600 RPM at all times. Since this is not usually possible, minor time errors in clocks occur.
MAINTENANCE ELECTRICAL TESTING GENERAL TESTING COILS FOR OPENS AND GROUNDS The main components of the generator are: field frame, field coils, armature, brushes. brush holder assembly, brackets, armature, and generator cooling fan. 1. Disconnect field leads from rectifier. 2. Set multi-meter to read resistance, and connect the meter leads to the field leads. If field is open, meter will read infinite resistance (very high ohms), repair or replace field if it is open.
TESTING ARMATURE FOR OPENS AND GROUNDS 1. Remove all brushes. 2. Ground fault test. Set milti-meter to read high resistance (mega-ohms). Holding one meter lead against a clean spot on the armature shaft, touch the other lead to each of the slip rings (one at a time) while observing the meter. If meter indicates continuity (any reading lower than one megaohm), the armature is grounded. Dirt between the slip rings and on the insulator surface can cause grounding.
TROUBLESHOOTING CHART SYMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION No output or low voltage. 1. Open or shorted armature. 2. Open or grounded field coil(s). 3. Generator operating below correct RPM speed. 4. Generator overloaded. 5. Short circuit in the load. 6. Loose (or broken) wires or connections in the control box. 7. Defective rectifier. 8. Dirty slip rings. 9. Brushes binding in holders. 10. Loss of residual magnetism. 1. Replace armature. 2. Replace field coil(s). 3.
