Energy Management System (EMS)
Overview
NO SHORE
AUTO
Screen images may vary slightly with continuous
improvements/firmware updates
The Energy Management System (EMS) is a function
of the Firefly Multiplex system� The electrical screen of
the central Multiplex panel (example above) displays
EMS data�
The system monitors the total current draw of the
coach’s 120 VAC power system� When running multiple
appliances or turning on devices like coffee makers
and vacuums, the system will temporarily shed other
loads (reduce/remove power from certain devices)
like the heating/hot water electric element to prevent
nuisance breaker tripping�
Upon decreasing the additional demand, and
approximately 2-3 minutes pass, the system will
automatically power up appliances and components in
reverse sequence�
Load shedding occurs in the following sequence
depending on the demand:
1� Heating/Hot Water System Electric Element
2� Air Conditioner Compressor
3� Cooktop
4� Microwave
The number of appliances and devices the system can
run simultaneously depends upon available power�
With a 15A shore connection, you may be limited to
one or two appliances before the EMS will begin to
shed loads�
Power Source selections for the EMS range from 15A
to 30A, depending on your current power source�
Navigate to the electrical screen on the central
multiplex touchscreen panel to see the current
selection next to the block titled Power Source; see
Multiplex System on page 5-18 �
120 volt System
City Power Overview
When plugged into shore power, the Volta Power
System Flex Pack samples incoming power for a few
seconds to ensure uniformity requirements exist� If
incoming power meets the requirements, the Volta
System begins charging the Flex Pack battery (house
battery)� If the Volta System is on when establishing
a shoreline connection, the Battery Power On/Off
Pushbutton (battery disconnect) LED will remain
solid green� If the System is off when establishing a
shoreline connection, the Pushbutton LED will flash
green� For more information, see Pushbutton LED
Flash Codes on page 5-12 and see Charging via
Shoreline Connection on page 5-15�
120 VAC shoreline power (city power) enters the coach
through the SmartPlug Cordset shoreline connection,
Smartplug inlet, and distribution panel, where it is
distributed to each appliance or receptacle� The 120
VAC electrical system provides power to operate the
A/C, converter, and 120 VAC receptacles for portable
appliances�
The inverter/charger converts shoreline 120 volt
alternating current (120 VAC) to direct current (DC)
power to charge the battery pack and diverts 120 VAC
shore power to 120 VAC systems�
All wire, components, and wiring methods meet federal
and state requirements� The wiring is protected by
circuit breakers when connected to external AC power�
The circuit breaker panel for the 120 volt system is
inside the Power Center; see Power Center on page
5-7�
If an outlet or appliance is not working, check your
touring coach circuit breakers and the breaker at the
shoreline connection� If a breaker continues to trip after
you have reset it several times, your circuit may be
overloaded with devices/appliances, or there may be
a short in the circuit� The Energy Management System
(EMS) should shed loads to prevent breakers from
tripping� Ensure the Power Source on the electrical
screen matches your incoming power source� If all else
fails, try lessening the load on the circuit by turning off
devices while using external appliances like vacuum
cleaners� If that does not solve the problem, consult an
Airstream Service Center�
WARNING
Do not connect the Volta System to a 240 VAC
outlet. Connecting to a 240 VAC outlet may result
in permanent damage not covered by warranty.
