Interior

SeeLevel II Monitor Panel

The display is the only system component that is
accessed by the user� The display shown above
is located in the overhead cabinet behind the the
Multiplex Touchscreen� All user input to the display is
done using the four buttons along the bottom of the
display�
NOTE
The following information is for use of the SeeLevel
II Monitor Panel. The Multiplex Systems main
control panel can also be used.
The display receives the information from the three
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 is pressed before 5 seconds, 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�
5-20
3� To continuously display a reading, press and
release the desired button, and then press the
same button a second time� When the button is
released, the display will be on hold mode, which
is indicated by the decimal point on the right hand
side turning on� While the display is in the hold
mode it will recheck the level once per second
so the user can watch the level change while the
tank is being filled or drained. The display will
automatically shut off after 5 minutes in hold mode�
To end the hold mode before the 5 minutes is up,
press any tank button, and the display will shut off�

To Read the Battery Voltage

1� Press the BATT button and release it, the display
will show the battery (House) voltage on the LED
display
2� If no other button is pressed, then the display will
shut down after about 5 seconds� If the BATT
button is held down, the display will continuously
recheck the voltage and show the updated value�
The reading may flicker back and forth between
two values�
3� If another button is pressed before the 5 second
time is up for the BATT button, the display will
immediately switch to show the value for the new
button� The 5 second time-out is restarted every
time a button is pressed�
4� There is no hold mode for the battery voltage

Solar System

Airstream utilizes Zamp solar panels and a Sun-
Explorer charge control and display� 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�
