    Sequence of Operation

    See "Sequence of Operation" under Additional Information for details.

    When utility power fails for just 3 seconds or more, the Series 165 Automatic Transfer Switch signals the generator to start.
    In less than 30 seconds your electrical power is restored and life returns to normal.
    Once the Series 165 Automatic Transfer Switch senses utility power has reached an acceptable voltage level for a period of time, it automatically reconnects your home or business to commercial power.
    It then smoothly shuts the generator down after a one minute cool down period to extend generator life.
    The Series 165 Automatic Transfer Switch automatically performs a test to simulate utility power failure every 14 days.
    The user-friendly control panel also allows you to manually run a test at the push of a button.
    LED indicators let you know the availability of both power sources and transfer switch positions.
