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 portable 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 2. FIRE HAZARD - Natural gas and L.P. present a hazard of possible explosion and/or fire. 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.
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.
water temperature shutdown has a 60 to 90 second lockout, allowing the engine time to clear the hot water out of the block in case of a hot restart. In addition if the generator should lose output during a run cycle the engine will continue to run for about 60 seconds and then shutdown and display an overcrank light. The starter will not reengage during this time or until the generator selector switch has been cycled off and back on. This is the only way to clear a fault light.
INSTALLATION FUEL INSTALLATION General Information The fuel supply should be as close as possible to the engine. This will reduce the installation cost of fuel runs. The information in this manual is offered to assist you in providing the proper fuel for your engine. However, this information is only provided to inform you of the engine’s requirements and assist in making you aware of the decisions you must make.
generally adequate for distances up to 300 feet from the primary to the secondary regulator. (Consult your local fuel supplier for your exact requirements). The appropriate line size from the table below is then installed from the second regulator to the generator set. ************* ***** WARNING **** ************* PERSONAL DANGER - Do not use galvanized pipe in fuel line runs. The galvanized coating can become eroded and flake off, causing possible obstructions in the regulator or fuel valve.
Tank Fuel Solenoid 1 Converter Engine 3 4 2 Reference number 1 is the fuel tank. No regulator is required but the tank must have a liquid withdrawal drop tube installed in it and a liquid valve on the tank. Reference number 2 through 4 are installed on the engine generator set. NOTE: Alway 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.
sufficient to handle your complete service. (I.E. your main line breaker rating does not exceed the line side contactor rating.) See Figure 5. If you have a larger main line breaker, you will not be able to transfer the complete electrical system.
The line terminals in the A.T.S. are marked “LINE - L1, LN, L3”. The “hot” leads L1 and L3 will wire directly to the top lugs on the line side contactor. The L-N connection will be made at the neutral bar on the standoffs on the floor of the A.T.S. The load terminals in the A.T.S. are marked “LOAD - T1, T-N, T3”. The “hot” leads T1 and T3 will wire directly to the load lugs between the contactors. s. The T-N connection will be made at the neutral bar on the standoffs on the floor of the A.T.S.
D.C. ELECTRICAL INTERCONNECTION INITIAL START UP PSS50000 and PSS65000 ************* ***** WARNING ***** ************* Two control wires are required between the A.T.S. panel and the generator control terminal box. Depending on the distance, 14 to 16 gauge stranded wire should be used. These wires will be labeled S1 and S23.
** Notice ** If for any reason during the check out procedure the voltage and frequency are not correct, turn the selector switch to the “STOP” position and correct the trouble before proceeding. After verifying the that voltage and frequency are correct, turn the selector switch to the “STOP” position. The unit should shut off with no time delay. You are now ready to test the automatic start function. Move the selector switch on the engine generator set to the “AUTO” position.
If, when you finish programing 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 progam 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 the clock is a small button marked "R". This is a reset switch.
LP/NG FUEL ADJUSTMENTS FUEL TYPE CONVERSION **** CAUTION **** If it should be necessary to change the type of fuel being used after the unit has been shipped from the factory it will be necessary to change the air gas valve assembly in the vapor fuel carburetor. The following conversion procedures are provided. EQUIPMENT DAMAGE - Do not make any fuel adjustments or governor adjustments until all pressure readings are in compliance with specification. See fuel pressure charts (tables 1, 2, and 3).
PROPANE VAPOR TO NATURAL GAS 1. Turn off fuel supply. 2. Remove the fuel line from the carburetor at the demand regulator. 3. Invert the regulator so the column is in the upright position. Remove the cap on the upright column of the regulator. This will expose the pressure spring adjusting screw. Turn the screw all the way out (CCW) and then back in (CW) about 8 turns. The plug should be approximately half way down for initial starting. 4. Remove the Air Cleaner to expose the top of carburetor. 5.
