The Intelli-Tank Level 40 (ITL40) is designed to display a liquid’s volume to an eighth of a tank level accuracy through
180-degree viewable ultra-bright LEDs. An Intelli-Tank Level 40 set as a MASTER uses a 0-5 PSI (0-34.47 kPa,
0-0.3447 bar) pressure sensor to obtain tank level information and then relays that information along the
communication line(s) (1-Wire or CAN) to ITL40’s set as REMOTES. Multiple REMOTE units can be linked to the
MASTER tank level.
2.2. Part numbers
Tank Level Gauge C1 – p/n 118404-01 – Red LEDs
p/n 118404-02 – Amber LEDs
p/n 118404-03 – Yellow LEDs
p/n 118404-04 – Green LEDs
p/n 118404-05 – Blue LEDs
p/n 118404-06 – 2 Red, 2 Yellow, 2 Blue, 2 Green rows of LEDs
Master When the ITL40 display is calibrated with a proper pressure signal it automatically becomes a MASTER
display and will send tank level information along the communication line(s) (either 1-wire or CAN) to all
other REMOTE displays.
Remote ITL40 displays are initially shipped as REMOTE displays. A REMOTE display only requires power,
ground and communications line(s) (either 1-wire or CAN). The REMOTE display mimics the MASTER
display’s LEDs by reading the appropriate information on the communication line(s).

3.3. Calibration
The ITL40 display can be calibrated five different ways: 1-point (quick calibration), 2-point (level calibration) empty
then full, 2-point (level calibration) full then empty, 5-point and 9-point (volume calibration).
To enter calibration mode use a magnet and activate the magnetic switches in the order of the appropriate password.
Entering an invalid password will initiate a “password error” pattern on the display (“X”
flashed four times). The unit will then resume its normal operation and the user can
attempt to re-enter the password.
Calibrate the unit by entering the desired point calibration password –
1 point RLLR LRRL
(see section 3.3.1)

3.3.6. Calibration retention
Calibration data is saved in non-volatile memory (EEPROM) and the display does not need power to retain
calibration data.
3.3.7. Invalid calibration
Calibration automatically makes the ITL40 a MASTER display if the calibration is valid. An invalid calibration is
determined when any calibrated point is not at a higher level than the previous calibrated point, or if the sensor
voltage falls outside of the valid minimum (0.4V) or maximum (4.8V) range.
An invalid calibration is acknowledged by flashing “X” four times and then scrolling the text “CHECK SENSOR
VOLTS” followed by a continuous scroll of the voltage detected on the sensor’s signal (pin 6).

If the self test password is used on a MASTER display all REMOTE displays will also perform their self test.
3.5. Setting the di m LED level
The display can be dimmed by applying system power to pin 4 (Dim Display input). The ITL40 has 9 levels of
brightness available (9 = brightest, 1 = dimmest, default value is 3).
To select the dim level of the display use the magnetic switches to enter the password RLLR LLLR.
All of the LEDs will be illuminated during the set-up. Touch a magnet against the RIGHT switch and the display will
dim to the next level and show the dim value number (9 through 1). Release the magnet and again touch it against
the RIGHT switch again to drop to the next dim level. Once the dim level is at the dimmest setting (1) the next touch
of the magnet will cycle to the highest dim level (9).
When the dim level is at the desired point activate the LEFT switch to save and exit.
3.6. Show software version, device settings, and errors
The ITL40 can display its setting by entering the password RRRR RRRR.
The display will scroll the software version, unit type, communication method, and then display any errors.

3.10. Slosh dampening feature
Some applications (off-road vehicles, etc) may submit the tank to conditions of extreme movement which causes the
fluid to slosh producing significant fluctuation in the displayed tank level.
The ITL40 can counteract these conditions by averaging the rhythmic changes (sloshing) detected by the pressure
sensor creating a more consistent displayed tank level.
Example with the slosh dampening feature DISABLED (default).

Try to recalibrate. If condition remains, check if the sensor signal voltage (pin C)
changes as tank level increases. If it doesn’t, replace sensor. If it does, verify
depth of tank. It may be impossible to calibrate a tank with a depth of less than 6
inches.
The display is configured as a REMOTE. Recalibrate if a MASTER is required. If
the display is supposed to be a REMOTE check communication data lines for
continuity.
Check power (Pin 1) and ground (Pin 12) connection.
Check sensor wiring. Ensure sensor signal voltage (Pin C) is varying. If it does,
check for same signal changes at Pin 6 of tank level connector (if it is not the
same - repair wiring). If signal is good at both locations try re-calibrating.

If the display flashes “X” four times after entering a password, insure the display is
installed right side up. During power-up the display should turn on all LEDs and
then cycle them OFF starting with the top row, then the display should scroll the
custom greeting from right to left.
Check that the left and right magnetic switches are recognized by activating each
switch and verifying that the associated LEDs illuminate.
Check for large noise spikes on the 1-wire data line.
Insure that the display’s ground potential is the same as the MASTER’s.
Insure that the data line is not chaffed and making contact with other electrical
wires.
Check the pressure sensor for problems.

Recalibrate the display and take a voltage reading from the sensor (pin 6 on the
display’s connector) at each calibration point. When the calibration points again
look wrong check the voltages at those points and determine if they are the same
as the voltage reading taken during calibration – if they are not then replace the
sensor.
Insure the Dim input voltage on Pin 4 is at least 9V. Recalibrate dim setting
(RLLR LLLR). If display does not dim LEDs while in the dim configure mode,
replace display.
A calibration was started on the display but not completed correctly. Set the
display to a REMOTE display (LRLR LRLR) or calibrate it as a MASTER (follow
calibration steps exactly).
The display has had a unit type memory error.
Attempt to set the display back to REMOTE or MASTER as required.
Replace the display if this error cannot be corrected.
7.2. Using the display to verify pressure sensor signal voltage
The display can show the voltage level that it detects on the pressure sensor signal line by entering the password
LLRR LLRR.
The display will then scroll the text “VOLTS” and then continue to scroll the voltage detected at pin 6.
The display will continue showing the voltage until either of the magnetic switches is activated.
