. Exhaust piping must not terminate under loading plat- forms, structures, or near any opening in a building. . Where necessary, exhaust piping must be guarded and/or insulated to prevent burns. . Provide a clearance of at least 9 inches (229mm)(10 inches (250mm) recommended) between exhaust piping and any combustible material. . Keep exhaust piping well clear of fuel tanks, fuel lines, etc. 5.3. RAIN CAP A rain cap is recommended on the end of the exhaust pipe. The rain cap is attached to the end of the pipe and opens due to the pressure from the exhaust discharge force. The rain cap protects the exhaust system from the environment when the system is not running. 5.4. SPARK ARRESTOR Use of a spark arrestor is required by the U.S. Department of Forestry if located on lands under their jurisdiction. The spark arrestor is recommended in areas where combustible Page 15 6. INSTALLATION CHECKLIST BATTERY INSTALLATION . Battery is connected properly. . Recommended battery is installed. . Cables are clean and tight. . Terminals are coated with anti-corrosion grease, and terminal covers are positioned. FUEL SYSTEM . Complies with local and NFPA codes. . Fuel is connected and checked for leaks. . Correct fuel pressure (11-14 inches of water (0.6 psi) at all load ranges). . Load block adjusted for maximum power for natural gas fuel. LOCATION . Unit is fastened to the appropriate mounting pad. . Louvers are free from obstruction. . Exhaust is clear of flammable objects and debris. ELECTRICAL CONNECTIONS . Complies with local code requirements and all National Electrical Codes. . Utility is connected and present. . Transfer switch is connected. . All wires running outside of the generator are in NEC- approved conduit. *Note: Utility wires and transfer switch control wires must be in separate conduit. . Unit is grounded to an approved earth ground. COOLING AND VENTILATING . All inlets and outlets are free from obstruction. OTHER . Verify that the unit is filled to the proper level with the proper break-in oil. Adjust as required. Page 16 GENERATING SET OPERATION AND MAINTENANCE Page 17 7. PRE-OPERATION CHECK BREAK-IN During the engine break-in period, observe the following by all means: . Change engine oil and oil filter cartridge after the first 50 hours of operation 2. DAILY CHECK To prevent trouble from occurring, it is important to know the conditions of the engine well. Check it before starting. CAUTION To avoid personal injury: • Be sure to install shields and safeguards attached to the engine when operating. • Stop the engine at a flat and wide space when checking. • Keep dust or fuel away from the battery, wiring, muffler and engine to prevent a fire. Check and clear them before operating everyday. Pay atten- tion to the heat of the exhaust pipe or exhaust gas so that it can not ignite trash. 1) Oil or water leaks 2) Engine oil level and contamination 3) Amount of fuel 4) Amount of coolant 5) Dust in air cleaner dust cup 6) Damaged parts and loosened bolts and nuts 7) Emergency stop off. 8) Battery connections 9) Wiring in good condition 3. CONTROL PANEL The DSE 5120 automatic mains failure module has been primarily designed to start and stop the generator depend- ing upon the mains supply status. External autostart from a switch and user operated manual start is also provided. Additionally, you have the facility to view all the system operating parameters via the LCD dis- play. The DSE 5120 module monitors the engine, indicating the operational status and fault conditions automatically shutting down the engine and giving a true first up fault condition of an engine failure by a flashing COMMON ALARM LED. Exact failure mode information is indicated by the LCD display on the front panel. 7.1. Automatic Mode of Operation This mode is activated by pressing the pushbutton. An LED indicator beside the button confirms this action. When the mains supply fails (or Remote Start signal (if con- figured) is applied) the following sequence is initiated: The mains available LED extinguishes (if the sequence was started by mains failure) and the relevant mains over/under voltage LED will illuminate. The Remote Start Active indicator illuminates if the se- quence is started by the remote start input. To allow for short term mains supply brownouts or false start signals the Start Delay timer is initiated. After this delay, if the pre-heat output option is selected then the pre-heat timer is initiated, and the corresponding auxiliary output will energize. After the above delays the Fuel Solenoid is energized, then one second later, the Starter Motor is engaged. The engine is cranked for a pre-set time period. If the engine fails to fire during this cranking attempt then the starter motor is disen- gaged for the pre-set rest period. Should this sequence continue beyond the set number of attempts (fixed at 3), the start sequence will be terminated and Fail to Start fault will be displayed accompanied by a flashing shutdown sym- bo...
