Page 45: Operation
Operation Operation WARNING • Before starting the machine, carefully read section “2. Safety”. • It is forbidden to connect the set to the public grid and/or other source of electricity. • Continuous operation at low load In general, all machinery (in particular those equipped with motors with after-treatment devic- es) must operate with a load (i.e. - Page 46 Operation Power factor - cos ϕ The power factor is a data that depends on the electrical characteristics of the load. It indicates the ratio between the Active Power (kW) and the Apparent Power (kVA). The apparent power is the total power required for the load, given by the sum of the active power delivered by the engine (after the alternator has transformed the mechanical power into electrical power) and the Re- active Power (kVAR) delivered by the alternator.

Page 47: Checks Before Start-Up
Operation Checks before start-up 1 - Check that the battery disconnect switch is turned ON. D5265870 2 - Check the oil, fuel and coolant levels. 3 - Check that the engine compartment, radiator and battery access doors are locked. 4 - Check that there are no oil, fuel and coolant leaks. 5 - Check that there is no flammable or dirty material around the exhaust pipe. - Page 48 Operation 4 - Press the start button (3) to launch the generating set start sequence. Note The start button (3) only works when the LED (a) located above the AUTO button (4) is off (MAN mode). During the start-up phase, the LED (b), located above the start button (3) flashes and it lights up steadily when the engine is started. D5265890 5 - Before drawing a load, let the engine run for the time shown in the following table.

Page 51: Maintenance
Maintenance Maintenance WARNING • Before proceeding with maintenance, carefully read section “2. Safety”. Refuelling Use fuel, coolant and lubricants according to the ambient temperature. 7.1.1 Fuel The fuel required for stage V engines must comply with EN590 and ASTM D975. The cetane number of the fuel should be at least 45. In order to ensure an efficient and long service life of the engine, the fuel must be sulphur-free diesel fuel: • EN 590 •... -
Page 52: Engine Oil
Maintenance 7.1.2 Engine oil • To ensure adequate protection of the engine and keep it efficient for a long time, use only the recom- mended oil. Using different oils can reduce the life of the engine. • The viscosity must be appropriate to the ambient temperature. • The oil to be used must comply with the following specifications: CJ-4 Low S.A.P.S ACEA E6 Low S.A.P.S. Low S.A.P.S. (low sulphated ash, phosphorus, sulphur oil) keeps the catalyst in good working condition. SAE oil classification In the SAE classification, oils are identified according to the viscosity. -
Page 53: Coolant
Maintenance 7.1.3 Coolant The engine cooling system is fuelled with OAT: ENI ANTIFREEZE SPEZIAL coolant, mixed at 50% with dem- ineralised water. It is recommended to continue using the same coolant. If the type of coolant is changed for refuelling, the system must be thoroughly washed. By mixing with each other, the residues of additives of different types contained in the different liquids would create gelatinous substances that could obstruct the system. Use a mixture of 50% demineralised water and 50% low silicate ethylene glycol coolant. Use a coolant free from silicates, phosphates, borates, nitrites and amines. -
Page 54: Checking And Cleaning The Engine Air Filter
Maintenance 2 - Remove the cap (3) and pour the coolant into the radiator. 3 - Top up the liquid until it covers the pipes inside the radiator by about 5 mm. Note • Do not overfill the radiator; allow room for coolant expan- sion. 4 - Refit the cap (3) and tighten securely. D5265940 5 - After the top-up operations, run the engine for a short peri- od, check the coolant level again and refill if necessary. -
Page 55: Routine Maintenance
Maintenance Routine maintenance WARNING • Pay the utmost attention to the generating sets equipped with an automatic or remote interven- tion system. Make sure that the generating set does not start during routine maintenance or repair opera- tions by carrying out the following operations: Disconnect power to the generating set control board. - Page 56 Maintenance 7.2.2 Scheduled maintenance for KOHLER engines Every 100 hours • Check coolant level • Check engine oil level • Check for sediment and water in fuel filter/separator • Checking and cleaning the air filter Every 250 hours • Check and clean radiator fins • Check alternator belt Every 500 hours • Check rubber sleeves • Check fuel line hoses •...

Page 57: Precautions For Generating Sets With Automatic Or Remote Start-Up
Maintenance Precautions for generating sets with automatic or remote start-up • Pay the utmost attention to the generating sets with automatic or remote start-up system, including: ◦ Generators in emergency service to the mains. ◦ Generators with programmable automatic test function. ◦ Generators with remote control via PC, via telephone modem or GSM modem and other communica- tion systems. -
Page 58: Storage
Maintenance Every year • Check electric connections and clean control panel. • Replace the engine oil. Storage • Carefully clean the fairings and all other machine parts. • Run the machine with load every 10 days for 15-30 minutes. Doing so ensures proper lubrication of the engine, keeps the battery charged and prevents any blockage of the injection system. - Page 60 MOSA div. della BCS S.p.A.
