Intelli-Tank Manual (106759) 021502 – 1 – Class 1

The Intelli-Tank 4 light tank level is designed to display a liquid’s volume to an
eighth of a tank level accuracy through 180-degree viewable ultra-bright LEDs.
The unit set as a Master uses a 0 – 5 PSI pressure transducer to obtain tank
level information and then relays that information along the data line to units set
as Remotes. Multiple Remote units can be linked to the Master tank level unit.

Modes of Operation:
Master When the unit is calibrated with a proper pressure signal it

automatically becomes a Master Unit and will send tank level
information along the 1-wire data transfer line to all other Remote
units on the line.

Remote Units are initially shipped as Remote units. A Remote unit only

requires power, ground and the 1-wire data transfer line. The
Remote unit mimics the Master unit’s display by reading the
appropriate information on the 1-wire data transfer line.

Self Test When the self test password is entered the unit will perform a self

test and display the results on the display. A Master unit will
command all Remote units to perform the self test also.

Note: All units are shipped as Remote units. A valid calibration will set the unit
as a Master. A Master can be reset as a Remote by entering a password.

When the unit is first powered up the LEDs will cycle on individually starting with
the EMPTY (bottom) LED and then the LEDs will show current status.

• A Master unit properly connected to a functioning transducer will display
current tank level information.

• A Master unit not connected to a pressure transducer will alternately flash the
bottom two LEDs.

• A Remote unit connected to a Master unit (through the 1-wire data line) will
mimic the Master unit’s LED condition and flash rate.

• A Remote unit not connected to a Master unit will alternately flash the upper
two LEDs and the lower two LEDs. This indicates a “no data” condition.

alternately at the SLOW flash rate.

“Wave off” pattern : two center LEDs, two outer LEDs flashing quickly for 4 cycles.
