PACKAGED STANDBY SYSTEM INSTALLATION AND OPERATORS MANUAL PSS20000/E Automatic Transfer Switch PSS20000/E Engine Generator P/N 60706-151-2106-00
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 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.
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.
TESTING POLICY: Optional UL Automatic Transfer Switch Sizes 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. UNIT 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.

INSTALLATION FUEL INSTALLATION General Information NOTE: All PSS20000 units are tested on Natural Gas and shippped configured for Natural Gas. See page 6 for conversion to LP ************* ***** WARNING **** ************* Before proceeding with the installation, be sure the operation selector switch is in the stop position. These engine/generator sets are designed to be mounted on a concrete pad outdoors only.
voir. This is also true for the single dual stage regulators, they should also be minimum of 10 feet from the unit. If this is not done the demand regulator on the unit and the pressure regulator in the fuel line will interfere with each other. When this two (2) stage regulator system is used, a fuel line size of 1/2 to 5/8 inch is generally adequate for distances up to 300 feet from the primary to the secondary regulator. (Consult your local fuel supplier for your exact requirements.
LP LIQUID WITHDRAWAL FUEL TYPE CONVERSION The following is a block diagram of a typical L/P Liquid Withdrawal fuel system for the PSS20000. If it should be necessary to change the type of fuel used after a unit is received, the following procedures are provided. Tank 1 Fuel Solenoid 2 Converter 3 NATURAL GAS TO PROPANE Engine 1. Turn off fuel supply. 4 Reference number 1 is the fuel tank.
7. You are now ready to make the final fuel mixture adjustment. Refer to adjustment section in this manual. LUBRICATION Before starting the engine, check the oil and, refill if required, the crankcase with the proper weight/grade of oil, as recommended by the engine manufacturer’s maintenance instructions. The necessity of using the correct oil, and keeping the crankcase full cannot be over emphasized.
************* ***** WARNING ***** ************* All wiring must be done by a licensed electrician, and must conform to the national electrical code and comply with all state and local codes and regulations.
PSS20000 Three Phase (FIGURE 5) FIGURE 5 FULL SYSTEM THREE PHASE The three phase units are installed the same as the single phase units above, except a third power lead is added, (i.e. a G2 from the generator, L2 on the line side and a T2 on the load side). In the 120/240 volt configuration the G3, L3 and T3 will be the high voltage (wild) leg. The other difference is a three phase power monitor has been installed in the A.T.S. to monitor each phase for low voltage.
To wire the automatic transfer switch into the existing wiring, first determine which circuits will be on the emergency load circuit. If the entire load is to be transferred, the transfer switch can be wired in directly after the watt-hour meter or main entrance providing the service entrance ampere rating is within the transfer switch’s rated capability. All selected emergency circuits are removed from main distribution panels and reinstalled in the emergency distribution panel.
The relay in the clock will not work unless the transfer switch is installed and powered up. The relay needs 120 volts AC to operate. If, when you finish programming the clock, you get an “EEEE” on the display, it stands for error. The most common error is that the day of operation has not been properly set at each step or a program has been turned on and not turned off. (i.e. programs not properly grouped 1& 2, 3 & 4, 5 & 6, etc.) On the face of clock is a small button marked “R”, this is a reset switch.
TROUBLESHOOTING TABLES ENGINE WILL NOT COME UP TO SPEED AFTER IT STARTS. UNIT WILL NOT CRANK WHEN THE POWER FAILS. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14.

Incorrect wiring between transfer switch and generator. Defective start stop relay in the transfer switch. Circuit breaker tripped on engine control panel.
PREVENTIVE MAINTENANCE Reasonable care in preventive maintenance will insure high reliability and a long life for the engine generator set and the Automatic Transfer Switch. ************* ***** WARNING **** ************* When performing any type of maintenance on this equipment make sure the selector switch on the engine generator is in the off position. If you are working in the Automatic Transfer Switch, confirm with a reliable meter that all power has been disconnected.
