ATS- Automatic Transfer Switch 
ATS-automatic loading transfer panel is the standard configure of emergent power system. The panel detects the voltage and frequency of civil electricity timely. While there is something wrong, such as high voltage, low voltage, phase missing, electricity cutting off, etc., it will signal to start the generator set automatically; then the generator set starts as soon as receiving the signal; ATS panel controls the switch to run the power when the generating of electricity is balanced; after the civil electricity resumes balanced, ATS panel will control the switch from generating electricity to civil electricity after prolonged confirmation,resumes the civil electricity; simultaneity, it controls the generator set to shut down after cooled. To-and-fro, makes the automatic double-circuit system comes to be true. 
Advantage
Automatic Transfer Switch Equipment Automatic starting the engine
 Automatic starting the engine
 ATS can start generator set and switch on without manual intervention when there are some breakdowns like as city electricity cut off. 
 Automatic stopping the engine 
 when commercial power is ok  ATS let switch transform from standby power supply to city electricity,then stop the engine.
 Automatic protection
 If there are some breakdowns like as high engine oil temperature , abnormal voltage ATS will stop the engine immediately, and give out sound and light alarm signal, call attention to manual intervention.
 Three-time restart function
 Generator has three-time restart function, if starting the engine is failure in the first time, ATS restart the engine in the second time after delaying 5 seconds, if starting the engine is failure in the second time, it restart the engine in the third time after delaying 5 seconds, if only one time starting the engine is ok it will run according to re-establish program, if in the three times starting the engine is failure, it will give out sound and light alarm signal. 
 Automatic keeping starting state all along
 be equipped with manual and automatic operation mode
