PACKAGE STANDBY SYSTEMS PSS27LS/D PSS40LS/C INSTALLATION AND OPERATIONS MANUAL PSS40LS Engine Generator Set
SAVE THESE INSTRUCTIONS TABLE OF CONTENTS This manual contains important instructions that should be followed during installation and maintenance of the generator and batteries. 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.
IMPORTANT SAFETY INSTRUCTIONS 2. FIRE HAZARD - Natural gas and L.P. present a hazard of possible explosion and/or fire. a. b. SAVE THESE INSTRUCTION This manual contains important instructions that should be followed during installation and maintenance of the generator and batteries. 3. Read and understand all instructions in the manual before starting and operating the generator set. This engine generator set has been designed and manufactured to allow safe, reliable performance.
2) ENGINE/GENERATOR 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 generators 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.
Generator Protection and Metering Generator protection guards against over voltage, under voltage, under frequency, and over frequency. Over current and phase imbalance protection is available as an option at the time of manufacture. Each generator protection function has an adjustable pickup and time delay setting. Metered generator parameters include voltage, current, real power (watts), apparent power (VA), and power factor (PF).
J - Reset Push-button. This button is pressed to cancel a settings editing session and discard any settings changes. When pressed, this button also resets the Breaker Management PreAlarms K - Arrow Push-buttons. These four buttons are used to navigate through the front panel display menus and modify settings. The left- and right-arrow buttons are used to navigate through the menu levels.
The engine manufacturer has established an excellent world-wide 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.
Connect the fuel supply to the inlet of the fuel solenoid (see table for recommended line size). The pressure at the secondary demand regulator must be four to six ounces psi (per square inch) or 7 to 11 inches W.C. (Water column) for vapor withdrawal units. On units equipped with liquid withdrawal fuel systems full tank pressure is plumbed to the fuellock strainer mounted on the generator rails. The fuel converter mounted on the unit will handle both vaporization of the fuel and pressure reduction.
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. When installing or replacing batteries, use the proper group/size starting battery. The battery should be a Maintenance Free lead acid design. Deep cycle batteries will not work for this application.
Never fill the battery above the fill line. Over filling above the upper level line may cause the electrolyte to overflow, resulting in corrosion to the engine or nearby parts. Immediately wash off any spilled electrolyte following the procedure above. 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. All connections must be clean and tight.
B - Generator Circuit Breaker, This circuit breaker provides overload protection for the generator. Your power feeds from the transfer switch will connect to the bottom lugs on the circuit breaker. The generator power feeds have already been wired into the upper lugs. The table below gives you the circuit breaker size, lug wire sizes and torque specification.
generator control terminal box. Depending on the distance, 14 to 16 gauge stranded wire should be used. These wires should be labeled S1 and S23. CONTROL PANEL LAYOUT A - DGC-2020 Digital Gen-Set Control. See Explanation on page 3. B - DC Control Circuit Fuse. The 10 amp DC Circuit Fuse protects the 12 volt circuits and engine wiring harness against faults in wiring or control equipment. The fuse also prevents a discharge of the battery due to a circuit fault.
With the engine running smoothly check the no load voltage and frequency on the digital display. The voltage should be 208/240/ 480 AC depending on which model you have and a frequency of 59.5 To 60.5 hertz (Hz). If you have the proper voltage at the generator the next step is to check the voltage at the generator terminals in the Automatic Transfer Switch. The voltage between the G1 and the G3 terminals should be the same as it was on the generator front panel.

9. You are now ready to make the final fuel mixture adjustment. These engines were adjusted at the factory to produce about .7 to 3.4% CO. If you have the ability to test the CO, adjust the 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. PROPANE VAPOR TO NATURAL GAS 1. Turn off fuel supply. 2. Remove the fuel line from the carburetor at the demand regulator. 3.
