PACKAGED STANDBY SYSTEM INSTALLATION AND OPERATORS MANUAL PSS8B2W/C
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.
SAVE THESE INSTRUCTIONS This manual contains important instructions that should be followed during installation and maintenance of the generator and batteries. PROPER USE AND INSTALLATION You must be sure your new engine generator set is: 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.
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.
** NOTICE ** UNPACKING: Regarding Engines - This manual covers the generator portion of these units. See the separate engine instruction manual for engine-related problems, detailed engine information and engine warranty. ** CAUTION ** Be sure to check the engine oil level frequently, as specified in the engine manual.
Do not install any shock mounts between the base frame and the concrete pad. Engine vibration will be transmitted to the control panel causing erroneous start/ stop cycles and premature control failure. The unit should be mounted to allow for ample working room around it. A general rule to follow is five (5) feet clearance on all sides. See NFPA Code 37 for additional clearance requirements. FUEL INSTALLATION The fuel supply should be as close as possible to the engine.
the use of a simple water manometer. A manometer is calibrated in inches of water column. The second is with a pressure gauge calibrated in ounces per square inch.
Installation and servicing of batteries must be performed or supervised only by personnel knowledgeable of batteries and the required precautions. Keep unauthorized personnel away from batteries. 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. CAUTION – PERSONAL DANGER CAUTION - NEVER dispose of a battery in a fire. The battery is capable of exploding.
charge). This charger is mounted on the engine generator set in the same location as the other AC and DC connections. A.C. ELECTRICAL CONNECTIONS The battery tender receptacle is to be powered by a GFCI circuit and installed in accordance wth the United Startes National Electric Code. These AC wires can be run in the same conduit as the other AC leads from the generator. It is suggested that this circuit be fused for 15 amps.

WINCO UL ATS (ASCO165) See the ASCO installation manual for additional details on proper wiring of the Automatic Transfer Switch. The standby generator terminals in the A.T.S are marked “ALTERNATE L2 & L6”. The “hot” leads G1 and G3 from the generator are connected to the terminals L2 & L6. The normal line power terminals in the A.T.S. are marked “PREFERRED - L1 & L5”. The “hot” line power leads are L1 and L3 from your normal power supply are connected to terminals L1 and L5.
PROCEDURE Move the selector switch on the engine generator to the “RUN” position. The engine generator will crank and start automatically. If the engine fails to start, return selector switch to the “stop” position and correct the trouble before proceeding. With the engine running smoothly, check the no load voltage and frequency at terminals L2 and L6 in the ASCO ATS on the generator terminal block in the ATS. The voltage should be between 242 to 248 volts. The frequency should be between 61.
GENERATOR EXERCISER CIRCUIT The automatic generator exerciser is configured to automatically exercise the generator for 20 minutes once every fourteen days . In order to set and test the exercise circuit the right hand toggle switch on the generator control panel must be in the normal position. SETTING THE EXERCISER CIRCUIT Press and release the Automatic Generator Exerciser button. After about 8 seconds the exerciser light flashes 14 times to indicate that the exerciser circuit has been set.
ENGINE WILL NOT CRANK WITH GENERATOR SELECTOR SWITCH IN THE RUN POSITION. TROUBLESHOOTING TABLES 1. RED ALARM LIGHT IS ON The red alarm light on the engine control panel is an indication that the unit either failed to start during the last cycle or shut down before the cycle or outage was complete. Moving the toggle switch on the engine control to the off position will turn the light off and allow the engine to be restarted.
ATS PANEL WILL NOT PULL IN ON NORMAL POWER. PREVENTIVE MAINTENANCE See Automatic Transfer Switch Manual NO AC OUTPUT FROM GENERATOR. 1. 2. 3. 4. 5. 6. 7. 8. 9. Reasonable care in preventive maintenance will insure high reliability and a long life for the engine generator set and the Automatic Transfer Switch. Diodes on rotor blown. Defective capacitor(s). Defective rotor. Defective stator. AC short in the output leads. Unit has lost its residual voltage. Rotor loose on engine crankshaft.
