Automatic Generator Start (AGS)
Your Touring Coach is equipped with an Automatic
Generator Start System (AGS) which provides an
optional automatic control of your onboard generator
The purpose of an AGS system is to automatically
start (and run) the generator when the 12 volt electrical
system (house batteries) drops to a pre-determined
level� The AGS can be enabled to monitor the house
battery bank and when it reaches a certain level, the
generator will automatically start, sending a charge to
your batteries� This protects the system so that your
batteries will not go down farther� Once the batteries
receive a sufficient amount of charge, the generator
will automatically turn off� If you are in a location for an
extended period of time, this can help protect battery
bank when shore power is not available� You may also
have the ability to set predetermined times so that it will
not start during the night or during posted quite times in
a campground�
The automatic start function of your generator requires
you to manually enable it� This can be accomplished
by selecting "Auto Gen Start Enable"on the Multiplex
display and then pressing "on"� You will then see a
warning screen listing the safety issues associated
with AGS usage� You are required to acknowledge
these warnings by pressing and holding a button for 3
seconds or longer to enable AGS�
Once enabled, AGS will remain enabled until the
Sprinter Ignition is cycled or the generator is manually
operated� After the vehicle is started, the AGS will be
disabled� You can then return to the cabin to manually
re-enable the system� It will then remain active until
the vehicle is turned off� Any cycling, on or off, of the
vehicle ignition will disable the AGS functionality�
If the generator is manually stopped while running
and in an Auto Gen mode, it will disable future auto
gen starts until re-enabled at the multiplex screen� If
you manually start the generator when Auto Gen is
enabled, it will disable the future auto gen starts until
re-enabled at the multiplex screen�

Carbon Monoxide (CO) is a highly poisonous gas�
Moving Parts and electricity can cause severe personal
injury or death� To reduce exposure to these hazards,
always disable AGS before
1� Sleeping in vehicle, unless equipped with a
working Carbon Monoxide detector
2� Parking vehicle in a garage or confined space
3� Parking vehicle for storage
4� Servicing generator, batteries or other electrical
appliances
5� Fueling vehicle
Exposure to carbon monoxide, moving parts, and
electricity hazards are possible due to unexpected
starting of generator while in Auto Start mode.
Energy Management System (EMS)
The Energy Management System is located in the rear
roof locker above the TV� A complete, detailed EMS
manual is included with your owner's packet�
The ENERGY MANAGEMENT SYSTEM controls 120-
volt operated circuits to help keep the total 120-volt
current draw to less than 30 amps� When operating
on generator power the 120-volt draw will be less than
20 amps� These circuits may be any type load, but
are typically heavier loads, those whose use can be
"postponed" until a time when current is available for
their use�
Circuit Protection
Circuit protection for ALL 120 VAC loads are standard
residential resettable circuit breakers install in the
Power Center (120 VAC section)� Airstream has pre-
installed the correct breakers per RVIA (NEC) listing
requirements for the touring coach� The MAIN breaker
for the touring coach is 30 amp and feeds the branch-
breakers in the breaker box� Shutting off the MAIN
breaker will remove power to all branch loads, except
for receptacles on the Inverter circuit when the inverter
mode is "ENABLED"� The Inverter/converter contains a
resettable 20 amp input breaker and a 15 amp output
breaker� The remaining power center branch-breakers
feed individual loads and are defined by the label
affixed next to the breakers. The source for 120 VAC
power to the Power Center can come from either the
Shoreline plug when connected to a camp site or the
coach's own generator when running� If both sources
are "ON" the power feed to the Power Center will be
coming from the generator�
