Automatic generator sets, all components using domestic and foreign brand-name manufacturers. The main functions are: fault (electric phase, overvoltage, undervoltage, frequency, delay, or accept less frequency) passive start signal, automatic start generator unit; starting after the success of the delay, when the voltage, pressure, frequency of normal, can choose to automatically load the power supply when the electricity is normal; unit, load shedding, electricity supply, no-load operation for a period of time, automatic shutdown. Self locking function: when the unit is out of order, the automatic locking starting loop. Automatic protection function: three sets of starting failure, low oil pressure, high water temperature, over voltage, under voltage, overload, short circuit, overspeed, other faults.
