2. System Overview
The Intelli-Tank 4 light tank level (ITL) 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 communication line(s) (1-Wire or CAN) to units
set as Remotes. Multiple Remote units can be linked to the Master tank level unit.

2.2. Modes of Operation
Master When the ITL 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 ITL 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. Operation
3.1. LED indications
The ITL display uses the 4 LEDs to show the unit status (section 3.1.1), water level (section 3.1.2), and error
conditions (section 3.1.3).
3.1.1. Initial power ON indications
When the display is first powered up the LEDs will cycle on individually starting with the bottom LED (LED 1) and
then the LEDs will show current status.
• A Master display properly connected to a functioning transducer will display current tank level information.
• A Master display not connected to a pressure transducer will alternately flash the bottom two LEDs.
• A Remote display connected to a Master display (through the 1-wire or CAN communication line(s)) will
mimic the Master display’s LED condition and flash pattern.
• A Remote display not connected to a Master display will alternately flash the upper two LEDs and the lower
two LEDs. This indicates a “no communication” condition.

3.2. Magnetic switches
The display has two magnetic switches (left and right). The magnetic switches are activated by using a magnet and
touching the front of the display on either side of LED 2.
For best results the magnet should be positioned over the desired magnet approximately 2 inches from the front of
the display, pushed directly to the front of the display, and then pulled back to the start position.

The LEDs on the display will indicate which switch was activated (upper two LEDs = left switch, bottom LED = right
switch) for approximately half a second and then the display will go blank.
The maximum time between magnetic switch activations is two seconds. If longer than two seconds have passed
between activations the unit will resume normal operation and the password attempted will be reset.

3.3. Calibration
The ITL display can be calibrated four different ways: 1-point (quick calibration), 2-point (level calibration), 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 “wave off” pattern on the display. (Two
center LEDs, two outer LEDs flashing quickly for 8 cycles.) 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)
6 of 22
2 point RLLR LLRL
5 point RLLR LRLR
9 point RLLR RLLR
(see section 3.3.2)
(see section 3.3.3)
(see section 3.3.4)
During calibration, the process can be cancelled at any time by activating the LEFT magnetic switch. This will
allow the display to exit without showing an “incomplete calibration error” (section 3.1.3) on the next power
cycle.
3.3.1. 1 Point Calibration
1 point calibration only calibrates the full point. The empty calibration is always set to 0.55V (approximately 1.5
inches of liquid).
1. Make certain that the tank is FULL.
2. Enter the password RLLR LRRL. The display will respond by flashing the top LED twice. The display will
then revert to normal operation by displaying FULL (all LEDs on).
3.3.2. 2 Point Calibration
1. Enter the password RLLR LLRL. The display will respond by flashing the two center LEDs twice. The
display will then begin cascading the LEDs from top to bottom (drip).
2. Make certain that the tank is EMPTY and then activate the RIGHT switch to store that point. The display will
flash the top LED and then turn on all four LEDs.
3. Fill the tank and then activate the RIGHT switch. The display will respond by flashing the top LED then
lighting the two center LEDs and then reverting to normal operation by displaying FULL (all LEDs on).
3.3.3. 5 Point Calibration
1. Enter the password RLLR LRLR. The display will respond by flashing the two center LEDs five times. The
display will then begin cascading the LEDs from top to bottom (drip).
2. Make certain that the tank is EMPTY and then activate the RIGHT switch to store that point. The display will
flash the top LED and then turn on the bottom LED.
3. Fill the tank to the one-quarter tank point and then activate the RIGHT switch. The display will flash the top
LED and then turn on the bottom two LEDs.
4. Fill the tank to the one-half tank point and then activate the RIGHT switch. The display will flash the top LED
and then turn on the bottom three LEDs.

5. Fill the tank to the three-quarter tank point and then activate the RIGHT switch. The display will flash the top
LED and then turn on all four LEDs.
6. Fill the tank to the full point and then activate the RIGHT switch. The display will respond by flashing the top
LED then lighting the two center LEDs and then reverting to normal operation by displaying FULL (all LEDs
on).
3.3.4. 9 Point Calibration
1. Enter the password RLLR RLLR. The display will respond by flashing the two center LEDs nine times. The
display will then begin cascading the LEDs from top to bottom (drip).
2. Make certain that the tank is EMPTY and then activate the RIGHT switch to store that point. The display will
flash the top LED and then begin flashing the bottom LED.
3. Fill the tank to the one-eighth point and then activate the RIGHT switch. The display will flash the top LED
and then turn on the bottom LED.
4. Fill the tank to the one-quarter tank point and then activate the RIGHT switch. The display will flash the top
LED and then turn on the bottom LED and flash the second LED.
5. Fill the tank to the three-eighths point and then activate the RIGHT switch. The display will flash the top LED
and then turn on the bottom two LEDs.
6. Fill the tank to the one-half point and then activate the RIGHT switch. The display will flash the top LED and
then turn on the bottom two LEDs and flash the third LED.
7. Fill the tank to the five-eighths point and then activate the RIGHT switch. The display will flash the top LED
and then turn on the bottom three LEDs.
8. Fill the tank to the three-quarter point and then activate the RIGHT switch. The display will flash the top LED
and then turn on the bottom three LEDs and flash the fourth LED.
9. Fill the tank to the seven-eighths point and then activate the RIGHT switch. The display will flash the top
LED and then turn on all four LEDs.
10. Fill the tank to the full point and then activate the RIGHT switch. The display will respond by flashing the top
LED then lighting the two center LEDs and then reverting to normal operation by displaying FULL (all LEDs
on).
3.3.5. Calibration retention
Calibration data is saved in non-volatile memory (EEPROM) and the display does not need power to retain
calibration data.
3.3.6. Invalid calibration
Calibration automatically makes the display a master 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 transducer voltage falls
outside of the valid minimum (.4V) or maximum (4.8V) range. An invalid calibration is acknowledged by giving the
“wave off” and if this was a master display previously will show an “invalid calibration error” (section 3.1.3), while a
Remote will revert to Remote operation.
3.3.7. Calibration incomplete
If the calibration is not completed the display will continually flash the “incomplete calibration error” (section 3.1.3),
during all subsequent power cycles. This indicates that a calibration was attempted but never completed.
Recalibrate the display completely to remove this error condition.
3.4. Self test
The Tank Level can check its hardware for proper operation by entering the password RLLR LLRR.
The display will then cycle each LED ON individually starting with the bottom LED and then all LEDs will come on and
begin flashing between full bright and the calibrated dim level for 5 seconds. The display will then show the condition
of the self test for 5 seconds.
