After the LCD screen of controller shows that countdown, city's electrical anomaly are delayed, into " booting delay " state；
B. after booting delay, starter relay output does not such as start success in " starting time " interior generating set,
Starter relay stops output, and into " starting interval time ", waiting starts next time；
C. in the number of starts of setting, if generating set does not start success, the LCD of generating set automatic controller is jumped
To alarm panel, while LCD shows starting failure alarm；
D. in arbitrary one push start, if starting successfully, enter " safe operation time ", safe operation delay terminates
Afterwards, then enter " delay of booting idling " state；
E. at the end of booting idling delay, the generating set automatic controller generating state if generating set power generation is normal
Indicator light is bright；Requirement is carried as generator voltage, frequency reach band, then the side of generating set contact closure of ATS twin-power switch, hair
Motor group band carries, into normal operating condition.
Generating set autostop process：
City power recovery is normal in generating set normal operation, then enters " line voltage is normally delayed ", confirms that alternating current is normal
Afterwards, the alternating current status indicator lamp of engine controller lights, and ATS twin-power switch Generation Side contacts disconnect, alternating current side contact closes
It closes, generating set " shutting down delay " starts；After shutting down delay, it is defeated that Engine ECU (electronic control unit) shuts down relay
Go out；After generating set comes to a complete stop, into power generation standby mode.
