NOTE
The 16’ Caravel combination Black/Grey tank
requires only the “Black” button to be pressed to
view the current tank level. Pressing “Grey” will
result in “OPn” being displayed.
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�
