自动工作模式

(1)自投自复模式：控制器对两路电源进行监控，当两路电源都正常工作时，则负载由常用电源供电；当常用电源发生故障(断电或缺相)时，控制器发出切换命令使电源自动切换到备用电源，此时负载由备用电源供电；当常用电源恢复正常时，控制器再次发出切换命令使负载供电由备用电源返回到常用电源。

(2)自投不自复模式：其工作方式和自投自复类似，但只有当备用电源也出现故障时才自动返回到常用电源，否则将一直由备用电源给负载供电。

(3)电网-发电机模式：当常用电源发生故障时，控制器输出发电机启动命令，经短暂延时后断开常用电源，此时负载由发电机供电；当常用电源恢复正常时，控制器输出发电机停机命令同时电源自动切换到常用电源上，负载返回到由常用电源供电模式。

手动模式

在手动模式下，电源不能自动切换而需要人为操作，主要有常用电源供电、备用电源供电和断电再扣方式。

常用电源供电：强制常用断路器闭合，备用断路器断开。

备用电源供电：强制备用断路器闭合，常用断路器断开。

断电再扣：同时强制断开常用断路器和备用断路器或是闭合因故障而断开的所有断路器。

Automatic working mode

(1) Self switching and self recovery mode: The controller monitors two power sources. When both power sources are working normally, the load is powered by the commonly used power source; When the commonly used power supply fails (power outage or phase loss), the controller issues a switching command to automatically switch the power supply to the backup power supply, and at this time, the load is powered by the backup power supply; When the common power supply returns to normal, the controller issues a switching command again to return the load power supply from the backup power supply to the common power supply.

(2) Self switching and non self recovery mode: Its working mode is similar to that of self switching and self recovery, but it only automatically returns to the common power supply when the backup power supply also fails. Otherwise, the backup power supply will continue to supply power to the load.

(3) Grid generator mode: When a common power supply fails, the controller outputs a generator start command, and after a short delay, the common power supply is disconnected. At this time, the load is powered by the generator; When the common power supply returns to normal, the controller outputs a generator shutdown command and the power supply automatically switches to the common power supply, returning the load to the power supply mode from the common power supply.

Manual mode

In manual mode, the power supply cannot be automatically switched and requires manual operation, mainly including common power supply, backup power supply, and power off and re trip methods.

Common power supply: Force the common circuit breaker to close and the backup circuit breaker to open.

Backup power supply: Force the backup circuit breaker to close and the common circuit breaker to open.

Power off and re trip: Simultaneously forcibly disconnect the common circuit breaker and backup circuit breaker, or close all circuit breakers that were disconnected due to a fault.
