Solar System

Airstream utilizes Zamp solar panels and a Sun
Explorer Charger Controller/Display System� Cut
the cord to expensive daily shore power hook-ups
with the 12-volt solar charging system� Ensuring the
panels are clean, not partially shaded by trees or other
interference will promote solar charging�
The Sunexplorer charge control performs these basic
functions:
1� It senses when the battery is fully charged and
disconnects the charge current to avoid over-
charging the battery�
2� It resumes charging the battery when the battery
voltage has dropped sufficiently to accept
additional charge current�
3� It checks the availability of charge current, by
cycling the relay every 4 minutes� If there is
insufficient charge current available, it's internal
relay will disconnect the battery to prevent
discharge through the solar panels at night�
Three different colored LED's indicate the status of the
battery charge� Green = Full, Yellow = Partial, blinking
Orange = low� When orange LED is blinking, due to low
voltage, both the green and yellow LEDs will be dimly
lit� Manuals on their use are included with the Airstream
owner's packet�
For those units manufactured without the solar panel
option, a 3-port plug-in has been pre-wired on the
roof� This port allows for roof mounted solar panels to
be installed after manufacturing without the need for
running wires� A single port has also been pre-wired
in the front of the unit near the battery box� This port
is a quick plug-in for a portable solar charging kit�
These ports are designed for solar panels added after
manufacturing�

SeeLevel II Monitor Panel

The display is the only system component that is
accessed by the user� All user input to the display is
done using the three buttons along the bottom of the
display�
The display receives the information from the two
sender pads via a single, two-conductor wire, and
displays the level information in percent of full on a
three-digit, LED display� When the front panel button
for a particular tank is pressed, the display powers
up and displays the level for that tank� If the button
is pressed and released, the display will show the
level for about 5 seconds and then shuts down
automatically� If another button is pressed before the
display shuts down, then the new level will immediately
be shown� If the same button is pressed twice, the
display will hold on that tank and continue to show
updated levels for 5 minutes before shutting off� This
allows the user to monitor the filling or draining of the
tank� By pressing two buttons at once, the diagnostic
functions can be accessed�
Sender pads are installed and stuck to the sides of
the holding tank� The sender pad scans the water
level through the tank wall using digital techniques
programmed into the sender microprocessor�
To Read a Water or Sewer Tank Level
1� Press the button corresponding to the tank to be
checked and release it, the display will show the
levels in percent on the LED display� If no other
button is pressed, then the display shuts off after
about 5 seconds�
2� If another button (including BATT) is pressed
before the 5 second time is up for the first button,
the display will immediately switch to show the new
level or voltage� The 5 second time-out is restarted
every time a button is pressed�
