The Automatic Transfer Switch (ATS) constantly monitors the utility
If there is an interruption in utility service, the ATS disconnects the utility service from the distribution
panel and starts the generator.
When mains power fails the ATS will pause for a
set period (determined at set up by the engineer) to ensure you haven’t had a power spike.
the generator is producing power the ATS connects the generator to the distribution panel.
The standby generator is providing
power to the distribution panel. This process takes from 10-20 seconds.
ATS senses that utility service is properly restored, it disconnects the generator from the distribution panel and reconnects
the utility service.
After transferring back to utility service the generator goes through a cool down period of about
10-15 minutes, then shuts down.
The system is back in standby, ready to respond to the next power failure.
This insures that the system is indeed stand-by ready for the next time it is
called on to power-up in the event of a utility failure.
