Battery Separator; Protecting The Charging System; Monitor Panel; Inverter/Charger - Airstream Interstate 2020 Owner's Manual

Interior
If the touring coach is NOT plugged into an external
AC power source and the switch is turned to OFF the
batteries are disconnected and the 12-volt distribution
panel will not receive power from the converter� The
converter will not charge the batteries with the switch
in the OFF position with no shoreline power present�
The OFF position is intended for storage of the touring
coach or when power conservation is desired�
The solar panels will charge the batteries regardless of
the battery disconnect switch position� Likewise, if ON
or OFF, the generator will charge the batteries�
NOTE
As a safety precaution, the electric gas shut-off
solenoid closes automatically when 12-volt power
is disconnected, cutting gas to appliances. It will
reopen when power is restored.

Battery Separator

The Battery Separator system is located under the
driver's seat� It is designed as a solenoid priority
system to protect the chassis charging system from
excessive loading, while allowing house batteries to be
maintained by the Sprinter charging system�

Protecting the Charging System

The Battery Separator monitors the battery system
to determine if the batteries are being charged� The
charging can be accomplished through the inverter/
charger or the engine charging system� When the
engine battery or house batteries are charging, the
Battery Separator will engage, joining the two battery
banks� If charging ceases and voltage decreases in
either bank, the Battery Separator will disconnect the
two banks from each other, protecting the banks from
being discharged simultaneously�
NOTE
In the event the engine battery is depleted, Sprinter
recommends using a trickle charge only when
charging the battery. When jumping the engine
battery, do not use a power boost. Read and
follow battery charging procedures in the Sprinter
Owner's manual.

Monitor Panel

The "Home" screen of the Multiplex Systems main
control panel displays the fluid levels of the Black
Water, Grey Water, Fresh Water, and the LP gas tanks�
The panel also shows the voltage status of the main
(chassis) and the auxiliary (house) batteries�
The fluid monitoring system has been calibrated at the
factory for the size tanks the touring coach uses and,
therefore, should never need another calibration�

Inverter/Charger

The Inverter/Charger is a DC to AC inverter and a 50-
amp multi-stage battery charger� The remote control
module is mounted in the front locker behind the
drivers seat�
The Inverter/Charger charges the batteries and
converts 12-VDC to 120-VAC current for distribution
to the entertainment devices� To operate your
entertainment circuit the inverter must be ON, unless
connected to generator or shoreline power�
If power is not needed to the entertainment circuit
make sure the inverter is turned OFF to conserve
battery power� The inverter will have a slight power
draw even when turned off but the power consumption
will be even greater if left on�
NOTE
Airstream calibrates all settings at the factory and
recommends adjustments not be made.
