PACKAGE STANDBY SYSTEMS INSTALLATION AND OPERATIONS MANUAL PSS30/B PSS40/E
SAVE THESE INSTRUCTIONS TABLE OF CONTENTS This manual contains important instructions that INTRODUCTION should be followed during installation and maintenance GUIDE TO PRODUCT SAFETY of the generator and batteries. BASIC INFORMATION Description Read and understand all instructions in the manual DGC-2020 Engine Control Layout before starting and operating the generator set.
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.
FUNCTIONS DGC-2020 Digital Genset Controllers perform the following functions: temperature, battery voltage, speed, engine load, coolant level (from ECU), ECU specific parameters, and run-time statistics. 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.
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 worldwide 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. General Information The rated power of each engine-generator is limited by the temperature, altitude and all other ambient conditions specified by the engine manufacturer.
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 load current carrying wires (L) and (T) must be sized to handle the maximum load current without excessive voltage drop.
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. (Replacement AGC10A-250V) C - DGC-2020 Fuse. This 3 amp DC fuse protects the DGC-2020 printed circuit board. (Replacement AGC-3A-250V) D - Emergency Stop Switch (3). When depressed this switch will disconnect all the 12 volt power to the DGC-2020 shutting the engine down.
PROCEDURE Depress the “RUN” push-button on the front of the DGC. The engine-generator will crank and start automatically. If the engine fails to start, depress the “stop” push-button and correct the trouble before proceeding. 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).
