Page 29: Electrical Protection
4. Description Electrical protection 4.2.1 Main machine switch The generating set is protected against short circuits and overloads by a circuit breaker (1) located upstream of the system. Overload protection tripping is not instantaneous; it follows an overcurrent/time characteristic. The greater the overcur- rent, the shorter the tripping time. The rated tripping current refers to an operating temperature of 30°C. -
Page 30: Residual Current Circuit Breaker With Overcurrent Protection (Rcbo)
4. Description The differential relay has 2 tests, 1 of which is carried out automatically by the instrument: • Manual test (test button). • Automatic test of toroid-relay connection and release reel relay. The differential relay can operate correctly even in the presence of harmonic distortion or with very disturbed signals. If the internal temperature exceeds the operating threshold, the Fault led (3) flashes. The interruption of operation due to a failure of the torus (breakage of the connecting wire) or a fault of part of the internal circuits, leads to the automatic intervention of the protection. - Page 31 4.

Page 39: Operation
6. 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. • Operating conditions 6.1.1 Power The electrical power of the generating set, expressed in kVA, is the available output power at the reference environmental conditions and at the rated values of: voltage, frequency, power factor (cos ϕ). - Page 40 6. Operation For cos ϕ values lower than 0.8, the alternator must be downgraded, because, at the same apparent power, the alternator should provide a greater reactive power. For the reduction coefficients, contact the Technical Support Service. Asynchronous motor start Starting an asynchronous motor by a generating set can be critical, due to the high starting currents that the asynchronous motor requires (Iavv. = up to 8 times rated current In.). The starting current must not exceed the overload current allowed by the alternator for short periods, gener- ally 250-300% for 10-15 seconds.

Page 44: Exhaust Post-Treatment
6. Operation Exhaust post-treatment Generating sets with engines complying with STAGE V exhaust gas regulations require special devices to reduce the emissions of pollutants in exhaust gases. Depending on the engine output, the after-treatment system includes the following devices: Doc (Diesel Oxidation Catalyst): catalyst to purify exhaust gases • DPF (Diesel Particulate Filter): particulate filter that captures soot in exhaust gases • SCR (Selective Catalytic Reduction): device that purifies nitrogen oxides (NOx) in engine exhaust gases. • On engines with power from 19 kW to 56 kW, there are DOC and DPF devices. On engines with a power greater than 56 kW, there are DOC, DPF and SCR devices. 6.6.1 Particle filter (DPF) regeneration Regeneration is the term used to describe DPF cleaning. - Page 45 6. Operation Reset regeneration DANGER During reset regeneration, post-injection is employed, and fuel is burned directly within the DPF filter (through the chemical reaction occurring within the DOC catalyst). The exhaust temperature is very high (up to 600°C). Take the following precautions: Make sure that there are no people, animals or flammable material nearby, and that the place is •...
- Page 46 6. Operation Forced manual regeneration (static) Even if the DPF filter executes the regeneration command, if unladen or low-load operating conditions are frequently repeated, the filter regeneration does not occur. When the DPF pollution level reaches 100% or higher, the engine control module requires a forced manual regeneration. The buzzer triggers and the control panel shows the following conditions: ECU light indicator light (1) ON and flashing • ATT filter indicator light (2) ON. • Aftertreatment D5261410 ACK indicator light (3) ON and flashing • • PCD indicator light (4) ON. D5261420 Important • If indicator lights (1), (2) and (4) turn ON and indicator light (3) remains OFF, it means that the engine requires a regeneration, but the regeneration conditions are not met (e.g., due to the presence of an engine alarm, or the coolant temperature lower than 60°C).

Page 49: After-Treatment Status Display
6. Operation After-treatment status display The generator control panel provides information on the after-treatment system installed on the generator engine through the following functions: • Universal lamps display (icons). • Display of analogue and binary values. • Control of the post-treatment regeneration function by transmitting commands to the control unit. After-treatment screen The after-treatment screen is automatically displayed once one of the warning lights activates or changes state. - Page 50 6. Operation Active indi- Inactive indi- Exit activated Indicator light Alarm name cator light cator light This alarm is activated when the control unit sends information that the red light of the control unit is acti- vated. The ALARM output is not activated, after the light is turned off, the alarm disappears automatically. This output is active when the control unit sends an active "red light" flag, that is, it has detected a critical malfunction. Do not run the engine until a service check is carried out. This flag is taken from DM1 on J1939 standard ECUs. Some controllers provide this flag in their own pro- prietary frames, others do not provide the flag.
