Read and understand all instructions in the 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 engine generator set, it is important that you carefully read and follow the operating instructions in this manual.
2. 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, 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. FIRE HAZARD - Natural gas and L.P.
TESTING POLICY: 2) ENGINE/GENERATOR 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. PSS27LS- The engine generator set consists of a GM 3.0L, I-4 Industrial, four cylinder, liquid cooled engine equipped to run on L.P./N.G. fuel. The engine operates at 1800 rpm and frequency regulation is maintained by the electronic governor within .
The following pre-alarm and alarm setting have been programmed in the DCG: Pre-Alarm Low Coolant Temp (Deg F) 70 High Coolant Temp (Deg F) 210 Low Oil Pressure 25 PSI Overspeed N/A Battery Overvoltage 15 VDC Low Battery Voltage 10 VDC Weak Battery Voltage 7.5 VDC Coolant Temperature Sender Failure Oil Pressure Sender Failure Magnetic Pickup Failure Battery Chager Failure Enabled Loss Of Generator Voltage Alarm PROGRAMMING VIA THESE PUSH-BUTTONS AND ENTERING AN IMPROPER CODE CAN DISABLE YOUR GENERATOR.
The engine manufacturer has established an excellent worldwide engine service organization; engine service is available from a nearby authorized dealer or distributor; check the Yellow Pages of the telephone directory under “engines,” or ask the dealer from whom you purchased the power plant. The rated power of each engine-generator is limited by the temperature, altitude and all other ambient conditions specified by the engine manufacturer. Engine power will decrease 3-1/2% for each 1000 ft.
************* ***** WARNING **** **** CAUTION **** EQUIPMENT DAMAGE - Be careful when sealing gas line joints. Excessive sealing compound can be drawn into the solenoid, regulator or carburetor causing an engine malfunction. ************* FIRE HAZARD - All fuel runs should be installed by a licensed fuel supplier. FUEL PRESSURE (vapor system) Connect the fuel supply to the inlet of the fuel solenoid (see table for recommended line size).
Notice the preceding tables give two (2) different units of measuring fuel pressure. The first is with a pressure gauge calibrated in ounces per square inch. The second and most accurate is the use of a simple water manometer. A manometer is calibrated in inches of water column. NOTE: Always make sure that a new battery is fully charged before installing it on a generator set. Failure to do so can cause damage to the engine control module in the generator set.
plete electrical system. In this case it will be necessary to install a secondary emergency distribution panel or purchase a larger transfer switch. FIGURE 5 ************* ***** WARNING ***** ************* PERSONAL INJURY - Be certain the operation selector switch on the front of the A.T.S. Control is in the “stop” position and the main power switch “off”. For your own protection, verify these important safety precautions yourself with reliable instruments before proceeding. A.C.
system requires an isolated neutral, this neutral to ground bond can be isolated by removing the copper strap located between the LINE terminal L-N and the ground lug in the panel. This action, along with lifting the Neutral to Ground bond in the generator connection cabinet, will effectively change this unit to a fully isolated neutral system. The generator output leads in the generator connection box follow the same marking pattern. i.e.
There is no neutral connection point in these switches so all three neutral leads (line neutral, generator neutral and load neutral) should be connected together and taped up. See the prints enclosed with UL-ATS panel for additional information. ************* ***** WARNING ***** ************* EQUIPMENT DAMAGE - The UL-ATS panels are voltage sensitive. Do not attempt to use a 240 volt ATS on a 208 volt system. Doing so will cause damage to the control circuits in the ATS panel.
Restoring the line power will cause the generator side contactor in the A.T.S. to open and the line side to close as soon as the generator side is open. This sequence is controlled by the electrical and mechanical interlocks in between the two contactors in the A.T.S. panel. These interlocks ensure that you get a clean 'break before make' action in the transfer switch. The restoration of line power also sends a stop signal to the engine generator set. This stop signal will cause the unit to shut down.

mixture on the carburetor until you achieve the proper CO reading. If you don't have a CO meter follow the manual adjustment procedure later in this section. 8. Next the timing on the engine must be changed. As this unit was shipped to operate on LP the timing advance was set at 26 degrees. For operation on NG it will be necessary for you to reset the timing advance to 36 degrees. PROPANE VAPOR TO NATURAL GAS 1. 9. You are now ready to make the final fuel mixture adjustment.
