the ATS automatically starts
the engine and transfers the
load after the generator has
reached proper voltage and
frequency. This happens in
a matter of seconds after
the power failure occurs.
When the utility power has
been restored, the ATS will
automatically switch the load
back, and after a time delay,
it will shut down the engine.

times.
It’s for this reason that
many businesses and other
entities have invested in
