The main and general load branch-breakers are
operated similar to a light switch with up as “ON” and
down as “OFF”� If an overload condition or a short
occurs the switch will snap to the “OFF” position�
The load for this breaker will now be “OFF”� Before
resetting the breaker be aware of any device that may
have been plugged in or turned “ON” which may have
cause the breaker to overload� Unplug or turn “OFF”
the possibly faulty device before resetting the breaker�
To reset the breaker, firmly push the breaker switch
to the “OFF” position then back to the “ON” position�
If the breaker snaps back to the “OFF” position while
resetting a fault condition still exists and should be
serviced by a qualified Service Technician. If the
breaker stays “ON” but snaps back to “OFF” after
plugging in or turning ON the possibly faulted device a
fault condition may exist in that device and should be
service by a qualified Technician.
The power center Ground Fault Interrupt Circuit (GFIC)
breaker is a special breaker that will provide additional
safety to the occupants of the touring coach on the
following receptacles; external, galley, lavatory, and
entertainment� In addition to short circuit and overload
protection the GFIC will shut off the breaker if any
current feeding out of the breaker does not return to
it� As in the case of a person contacting the electrical
energized part of the GFIC circuit and an electrically
conductive object not associated with the circuit�
Refer to to Ground Fault Circuit Interrupter and GFCI
Breaker Test in this section for more information�
Operation
In operation, when 120 VAC and 12 VDC are initially
applied, the system will energize the relays at one
second intervals, closing the normally open contacts
on each of the five relays while monitoring the total
current� If the total should exceed the service limit, the
system will turn off the last load that was turned on� As
it does this, it calculates the amount of current that was
removed, which is the value for that load� This value
is placed in memory� The system has “learned” the
amount of current that particular appliance draws� This
feature compensates for the difference in current draw
over a range of line voltage and ambient temperature,
by relearning the load each time it is turned off�
The system now waits until the total current is lower
than the service limit, by the amount in memory, before
it will turn that load back on� This ensures that there is
sufficient current to operate the load.
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
WARNING
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 front
locker behind the drivers seat� 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�
