How to Start and Operate Cummins Generator Correctly?
Start the diesel generator set
a. Do not start Cummins diesel generator with load
b. Press the start button. If the start is unsuccessful, wait for about 20 seconds before trying again. If the start is unsuccessful for 3 consecutive times, stop the start and remove the fault factors such as battery voltage or oil circuit before starting. Note that continuous start-up in a system that is not working properly will cause unburned gas to accumulate in the exhaust system, posing a potential explosion hazard.
c. For the mechanical speed regulating unit after the start of idle speed for about 1 minute, then the throttle is gradually raised to 1500r / min; electronic speed regulating unit, no need to adjust.
d. To start the diesel genset in a cold environment, preparation must be done. Use winter fuel suitable for local temperature (qualified brand). This can reduce the risk of waxy deposits in the fuel injection system. In the case of extremely low ambient temperature, it is recommended to install a preheating system (water jacket preheating, oil heating, fuel heating) and ensure that the cooling system is filled with antifreeze.
e. The battery must be in good condition. Low temperature will reduce the capacity of the battery. Depending on the actual situation, it may be necessary to increase the capacity of the battery.
f. Manual, automatic, three-remote control cabinets and ATS cabinet in non-standard units, please refer to the corresponding random data for the use of the cabinet.
Diesel generating set is in operation
a. Check the oil pressure, water temperature, voltage, frequency, etc. of the control module. If there is any abnormality, stop the machine immediately for inspection. After the fault is removed, the unit can be started again.
b. Check the oil circuit, waterway, gas circuit and smoke exhaust system of the unit for leaks. Check the connection of the unit for looseness and severe vibration. Check whether the various protection and monitoring devices of the unit are normal.
c. When the rotation speed reaches 1500r/min and the no-load operation is stable, the switch can only be closed to supply power to the load. The unit is not allowed to have continuous idle load of more than half an hour or less than 30% load operation. The gen set needs to be guarded when it is running. Overloading is strictly prohibited.
d. Do not short circuit when the unit is in operation, otherwise it will cause serious damage to the equipment. It is strictly forbidden to disassemble any parts of the generator set while it is running!
e. Do not reach under the fan shield and any other parts that have relative motion!
f. Do not try to touch the exhaust pipe, turbocharger, high temperature coolant, heater and other high temperature surfaces by hand, there is a danger of being burned!
g. Check the output voltage and frequency from the control panel. The output voltage of the unit has been adjusted at the factory, so it should be indicated within the normal range. For units with mechanical speed regulation, the frequency should be close to 52 Hz under no-load conditions; for units with electronic speed regulation or EFI speed regulation, the frequency is close to 50 Hz under no-load conditions.
h. Keep the load on the diesel generator set not exceeding the rated value. Some models can run 110% rated power continuously for 1 hour when necessary, but only after 1 hour of rated power operation.
