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 5-14 and see Charging via
Shoreline Connection on page 5-17�
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
5-8�
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� 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.
Energy Management System (EMS)
The Energy Management System is located in the
overhead compartment, behind the driver’s seat� A
complete, detailed EMS manual is included with your
owner’s packet�
The EMS controls 120-volt operated circuits to help
keep the total 120-volt current draw to less than 30
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�
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 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.
EMS Display
The display panel requires little user interaction
and is provided to help the user understand power
management� The display monitors the total AC current
of the touring coach and prevents circuit breaker
tripping by momentarily shedding loads� As additional
appliances are turned on the system will begin to shed
loads� As appliances are turned off, and a minimum of
two minutes has expired, the system will automatically
restore power to each of the shed loads�
