Ensure the safety and correctness of diesel generator operation.
2. Scope of application
It is suitable for the operation of Cummins-Stanford diesel generator set (EDI-550-CS).
3. Content
3. 1 Pre-startup inspection
3. 1. 1 Turn off the output automatic air switch of the generator set and put the selector switch on the generator control panel in the stop position; 0; Location.
3. 1.2 check the overall situation of the unit: whether there are sundries in the fuselage, whether the radiator network of the water tank is blocked, whether the fuselage leaks oil, etc.
3. 1.3 Check the air intake and exhaust of the machine room, and check whether the air intake and exhaust ports are blocked.
3. 1.4 check the oil level: twist the dipstick, which is marked with: h; (high) and; l； (low), the oil level should be between H and L, close to H, but not more than; Check whether the oil quality is deteriorated and blackened.
3. 1.5 Check the diesel fuel tank: whether the fuel tank is full, whether the pipeline leaks oil, whether the exhaust port is unobstructed, whether the gate valve is open, etc.
3. 1.6 check the water level in the cooling water tank: unscrew the water tank cover, and the middle finger can detect the water level or observe that the water level is 2 ~ 4 cm below the plane of the water tank cover.
3. 1.7 Check whether the battery wiring and other leads of the unit are firmly connected.
3. 1.8 Check that the terminal voltage of the battery displayed on the display screen of the generator set (DSE plc model 560) should be DC24V, and there is no symbol indication such as warning.
3.2 Manual startup.
3.2. 1 Place the selector switch on the panel of the fan and exhaust fan control box; Manual; Position, press the start button to send the exhaust fan to run.
3.2.2 When the power supply stops, disconnect the power contact switch in the distribution room. When testing power generation, disconnect the generator set.
Output automatic air switch.
3.2.3 Turn the selector switch on the control panel of the generator set to; Manual; Position, the generator set will start to generate electricity.
3.2.4 Listen for abnormal sounds and use the operation buttons on the display screen; ▽; Observe whether the generator voltage, current, frequency, speed, oil immersion and engine temperature are normal.
3.2.5 If the engine fails to start smoothly, the starting motor will be separated from the engine mechanism after several tens of seconds, and an alarm signal will be sent out. The restart step is to wait for 2 minutes, let the starting motor cool down before restarting. If you still can't start the generator, you need to troubleshoot the corresponding display screen.
3.3 Automatic startup
Place the selector switch on the control box panel of blower and exhaust fan in the center; Automatic; Position, put the selector switch on the control panel of the generator set in the automatic position; Automatic; Location. When the power supply is cut off, the wind turbine will start automatically and the generator set will start generating electricity automatically.
3.4 downtime
3.4. 1 Shutdown in automatic state
When the commercial power returns to normal, the commercial power circuit breaker will automatically close, and the interlocking emergency power circuit breaker will be disconnected. The diesel generator set will automatically stop after three to five minutes of no-load operation, and the air supply and exhaust fan will also automatically stop.
3.4.2 Shutdown in manual mode
3.4 ...2. 1 First cut off the load at the back end of the generator set, and then disconnect the automatic air switch at the output end of the generator set.
Turn the selector switch on the generator control panel to the stop position after no-load operation of 3.4.2.2 generator set for 3-5 minutes; 0; Position, the generator set will stop running.
3.4.2.3 is pressed on the panel of the blower and exhaust fan control box; Stop; Button to turn off the blower.
3.4.2.4, after checking everything is normal, put the selector switch on the generator control panel; Automatic; Position, close the generator output automatic air switch.
3.4.2.5 will send, exhaust fan control box panel selection switch in place; Automatic; Location.
3.4.3 Emergency stop.
When an emergency is found and the generator's own protection system refuses to operate, the operation can be stopped by pressing the red emergency stop button on the control panel of the generator set.
3.5 Preventive measures
3.5. 1 Check before starting the generator to ensure that everyone is away from the generator to avoid personal injury accidents.
3.5.2 When starting the generator set for the first time or replacing the oil or oil filter, stop the generator after running for a few minutes, wait for 15 minutes for the standby oil to return to the oil pan, and check the oil level of the generator again. If it is not enough, add it to make the oil level close to that on the dipstick. h； At the mark.
3.5.3 After the generator set is completely normal and stable, the power transmission output can be switched on. The load of all kinds of power equipment must be put into operation by stages and with delay, and heavy load or full load cannot be put into operation at one time.
3.5.4 During the operation of the generator set, special personnel shall be assigned to guard the generator set and regularly check the operation of the generator set.
