Generator automatically switch cabinets (also known as dual-power automatic switching cabinet) is mainly used for automatic switching power supply and backup power generators, it is with self-starting generator set up the automatic supply system together, can be used after the power outage Fire Equipment , emergency lighting and other loads to switch to emergency power generators, a power supply and fire requires high banks, hospitals, telecommunications, radio and factories. In this paper, I will introduce dual power automatic switching method switch between generators with the operation.

1、Manual operation mode
First you need to supply key switch to manual operation position, and then press the "Manual" button to operate directly, after successfully running the generator set, so the generator into the boot automation module self-test, automatically increases the speed state after the passage until the power supply stable.

2、Automatic operating mode
Conventionally, dual power are Default As for the "automatic" state, generator sets in quasi-work state, dual power automatic mains status of long-term monitoring and fault identification, once common mains fails, automatic start work immediately enter state, load switch to backup generators. And when the utility power is restored to normal, after delay confirmation systems, generators automatically quit working condition, after a certain delay, automatically shut down and resume to monitor the quasi-state.
