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. PSS50LS- The engine generator set consists of a GM 5.7L V-8 industrial, 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 .
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 N/A N/A N/A Enabled Enabled Enabled SPECIFICATIONS GENERATOR MODEL During normal operation the DGC will continuously display the engine oil pressure, coolant temperature and the battery voltage reading.
***** CAUTION **** UNPACKING INSTRUCTIONS ** NOTICE ** When unpacking the generator set, be sure to inspect it carefully for freight loss or damage. If loss or damage is noted at the time of delivery, require that the person making the delivery make note of the loss or damage on the freight bill, or affix his signature under the consignees’s memo of the loss or damage. Contact the carrier for claim procedures.
INSTALLING THE FUEL LINE FUEL PRESSURE (vapor system) ** NOTICE ** Correct fuel pressure cannot be stressed enough. The most common cause for inoperative systems is an inadequate or incorrect fuel pressure. Performance of the engine is in direct relation to the correctness of the fuel system. Shown below is a block diagram of a typical L.P. or N.G. Installation.
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.
not be able to transfer the complete electrical system. In this case it will be necessary to install a secondary emergency distribution panel or purchase a larger transfer switch. .1/74- # ************* ***** WARNING ***** ************* Service Entrance 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”.
All the neutral leads (G-N, L-N and T-N) must be carried through the A.T.S. These leads are all bonded together within the A.T.S. and are bonded to GROUND at one common point. If your 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.
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.
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 activate the 5 minute timer circuit and shut down the unit 5 minutes later. This completes your installation and unit testing. ALWAYS leave the system in standby mode unless servicing the unit. For standby operation, keep both the generator set and transfer selector switches in the “AUTOMATIC” position. 8.
