Energy Management System (Ems); Circuit Protection - Airstream TOMMY BAHAMA 2020 Owner's Manual

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 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�

WARNING

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�
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 Circuit Interrupter
(GFCI) 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 GFCI 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 GFCI 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�
