System Diagram
The SerieS 185 Automatic Transfer Switch incorporates
the latest technology developed by ASCO for depend-
able operation in any environment
• When utility power fails for just 1 second or more,
the SerieS 185 Automatic Transfer Switch signals the
generator to start
• In less than 30 seconds your electrical power is
normally restored
• Once the SerieS 185 Automatic Transfer Switch senses
utility power has reached an acceptable voltage level
for a period of time, it automatically reconnects your
power
• It then smoothly shuts the generator down after an
adjustable 2 - 5 minute cool-down period to extend
generator life
• 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
Performance sets the series 185 apart
