INTRODUCTION
Overview
The FRC TankVisionPro indicator shows the actual volume of liquid in a tank. The
liquid in the tank exerts a pressure that is measured by a sensor. As the amount of liquid
changes, the pressure it exerts on the sensor changes proportionally. The pressure change
is used to calculate the exact volume of liquid in the tank. The TankVisionPro can be
calibration to accurately display the volume of liquid in tanks of all shapes and sizes.
The display module is able to communicate with other display modules over the
FRC datalink. This allows for one master display module to control multiple displays.
The module also provides an output for cab miniature displays, remote light drivers,
and a low level warning buzzer.
The TankVisionPro indicator is a unique design made up of an extended wide view
lens with 9 or 10 super bright LEDs (depending on the chosen conguration) mounted
behind it. This allows the display to be visible and clearly read from all line-of-sight
angles for a full 180 degrees.
The pressure/vacuum foam tank vent is supplied for use on foam concentrate storage
tanks. These tanks should remain closed to the atmosphere. The FRC vent enables
the tank to compensate for changes in pressure or vacuum due to thermal expansion,
lling, or when withdrawing foam concentrate from the tank.
The MaxVision LED tank display provides a remote, wide angle view of how much
water or foam concentrate is left in the tank in fractional 1/8 tank eight level increments.
The remote light driver provides the option to have four 60 watt remote lights
controlled by the TankVisionPro to show full, 3/4, 1/2, and 1/4 tank.

WLA300 Rev170606
Display Module
The tank display module is waterproof and has dimensions of 4.4 inches high by
3 inches wide. An output signal from a pressure sensor mounted on the tank is input
to the primary display module. It is processed and the volume of liquid in the tank is
shown on the 9 LED display as a fractional amount on the overlay (or available as
a percentage value for a 10 LED display). Outputs from the primary display module
provide tank volume information to other displays and remote devices.
WLA400 Series primary displays are used for Auto Tank ATA400 systems.
WLA300 Series primary displays can be programmed to use pin #5 for Auto Tank
ATA400 systems.
Cab Miniature Display (Optional)
The cab miniature display has dimensions of 2.75 inches high by 1.5 inches wide.
It provides the option of mounting a remote display in the cab that uses a minimum
of panel space. An output signal from the primary display module is input to the cab
miniature display and the volume of liquid in the tank is shown on the 5-LED display.
Pressure Sensor
The pressure sensor is mounted on a side of the tank near the bottom. It provides a
signal that is proportional to the volume of liquid in the tank to the input of the primary
display module. The electrical connector is waterproof and molded into the pressure
sensor housing.
The standard pressure sensor is used on tanks between 1 and 10 feet in vertical
height. For tanks taller than 10 feet contact FRC for options.
7
WLA300 Rev170606
Pressure/Vacuum Foam Tank Vent
The pressure/vacuum foam tank vent is supplied for use on sealed foam tanks.
The vent compensates for changes in tank pressure due to thermal expansion or when
withdrawing foam concentrate from the tank. Internal passageways provide a path
for air to move between the tank and a center cavity in the vent. These passageways
are self-draining and designed to prevent splashing foam from entering the center
cavity and clogging the pressure and vacuum valves. The pressure and vacuum valves
are easily accessed and disassembled for periodic cleaning or inspections. (Refer to
Maintenance section.)
Note: The vent can compensate for a maximum foam concentrate ow rate
of 60 GPM. If the ow rate of foam concentrate from the tank will exceed
60 GPM, two (2) vents will be required.
MaxVision LED Tank Display (Optional)
The LED display is waterproof and has dimensions of 14 3/8 inches high by 1 7/8
inches wide by 7/8 inch deep. It has 96 RGB LEDs and built in LED drivers. A signal
from the primary display module is output on a two wire datalink and input to the LED
light to show the volume of liquid in the tank.
The display shows the level in 1/8 tank increments. It has a photo sensor that adjusts
brightness for day or night operations. The LEDs are programmable for various display
modes and multiple brightness levels:
Note: The MaxVision LED tank display shows how much water or foam
concentrate is left in the tank in fractional 1/8 tank eight level increments.
Remote Light Driver (Optional)
The remote light driver is waterproof and has dimensions of 4 inches high by 2.75
inches wide by 1 inch deep. An output signal from the primary display module is input
to the remote light driver. This provides the option to power four (4) 60 watt remote
lights that show the volume of liquid in the tank. The lights will show full, 3/4, 1/2,
and 1/4 tank levels.
Buzzer (Optional)
The buzzer provides an audio alarm when the tank volume drops to 25%.
The buzzer resets when the tank volume goes above 25%.
Note: When the TankVisionPro WLA300 primary display is used to control
an Auto Tank ATA400 system, pin 5 does not provide a ground for the
buzzer. WLA400 Series primary displays are used for Auto Tank ATA400
systems. WLA300 Series primary displays can be programmed to use pin
#5 for Auto Tank ATA400 systems.

Install Pressure/Vacuum Foam Tank Vent
A pressure/vacuum foam tank vent is supplied for use on sealed foam tanks. The
recommended location to mount the vent is in the cover of the foam tank ll tower. If
there is no ll tower, mount the vent at the highest point of the tank top so that it is not
immersed in foam. For installations where clearance above the ll tower is limited, a
90° mounted vent is available.
Note: The vent can compensate for a maximum foam concentrate ow rate
of 60 GPM. If the ow rate of foam concentrate from the tank will exceed
60 GPM, two (2) vents will be required.

Install MaxVision LED Tank Display
The LED display is waterproof to allow for exibility in the mounting location.
Ensure that the light is mounted with the rear against a at surface.
Mount the display so that the raised MaxVision logo on the lens and the drain notch
on the rubber gasket are at the bottom and is mounted with the rear against a at surface.
The wires can be run through any one of the three holes in the rubber gasket.
Note: Before drilling holes place the light in position to check for t. Ensure
that the display clears all obstructions.
1. Measure and mark the mounting hole locations and through hole for the wiring.
2. Drill the two (2) mounting holes for #10 screws and a wire feed thru hole. Any
of the three locations (holes) in the rubber boot can be used for the wires.
Note: Ensure that the terminating resistor is installed on the datalink wires
when required.
3. Connect the wiring and secure the light with two (2) screws. (Refer to Wiring Section.)
Terminating Resistor Notes
The datalink requires two terminating resistors.
1. One TankVisionPro with one or two LED displays: Install one resistor
close to the primary display; install the other resistor farthest away from the
primary display, but closer to the remote display.
2. Two TankVisionPro displays: Install terminating resistor at both ends.
3. If the TankVisionPro is used with a TurboFoam system: Do not install
terminating resistor.
Program MaxVision LED Tank Display
The MaxVision acts as a remote, and the color pattern will mirror the pattern
chosen for the primary display. (See page 29 for detailed information about synching
primary and remote displays.)
Code Entry:
1. Hold a magnet over the calibration point for ve seconds. Two middle rows
of LEDs come on.
2. Swipe the magnet to select the program to be changed; a row of LEDs come
on with each swipe.
Brightness Adjustment:
1. Top 2 rows on - set daytime brightness.
2. Top 3 rows on - set nighttime brightness.
15
WLA300 Rev170606
3. Wait 5 seconds to enter the program.
4. Each swipe changes the LEDs brightness—ten levels that are stepped through
and then repeated.
5. Hold the magnet over the calibration point for ve seconds to load the new
setting. The display blinks three times to conrm setting is loaded.
Programming the MaxVision to Display Foam A, Foam B or Water:
Code Entry:
● Hold a magnet over the calibration point for ve seconds. Two middle rows
of LEDs come on.
Swipe 4 times to set the display for one of the following options:
● Water (Default option)—displays alternate Blue LEDs
● Foam A—displays alternate Green LEDs
● Foam B—displays alternate Yellow LEDs
1. Wait 5 seconds to enter the program.
2. Each swipe changes the choice from Water, to Foam A, to Foam B—the three
options are stepped through and then repeated.
3. Hold the magnet over the calibration point for ve seconds to load and save the
new setting. The display ashes or blinks three times to conrm setting is saved
and updated.
Programming the Color Pattern for the MaxVision:
The default setting for the color pattern is to have this synchronized with the primary
display (as described on page 29, Fig. 10). If it is required to have the MaxVision synchronize
with the primary display, activate the "Code Entry" (as mentioned on page 15), select Pattern
#10, wait for 5 seconds and swipe the magnet once. Save the setting by holding the magnet
for 5 seconds at the calibration point.
However, these same six color patterns from Fig. 10 (shown in Fig. 5) can be "locked
in" for the MaxVision only, separately from the color pattern shown on the primary display.
Additionally, there are three color patterns to display the status level of either Foam A
(all Green LEDs) , Foam B (all Yellow LEDs) or Water (all Blue LEDs). This allows for
customizing of up to nine different "locked-in" color patterns on the MaxVision display
(separate from the primary display).
Perform the following steps to select the locked in color pattern for the MaxVision:
1. Start the "Code Entry" by holding the magnet the calibration point for ve seconds.
Two middle rows of LEDs come on.
2. Swipe the magnet to select the program to be changed; a row of LEDs come on
with each swipe.
16
WLA300 Rev170606
3. Swipe the magnet once and in ve seconds the previously saved color pattern will
be displayed. The Red LEDs will all light up and scroll upward (as shown in Pattern
10). The Red LEDs scrolling upward means the MaxVision display is synchronized
with the primary display. The color pattern on the MaxVision will be identical to
the one on the primary display. (This is the default setting).
Each swipe changes the choice from each of the nine color patterns—the nine
options are stepped through and then repeated.
4. Hold the magnet over the calibration point for ve seconds to save the new color
pattern setting. The display ashes or blinks three times to conrm setting is saved
and updated.

When power is applied, the remote light driver runs a lamp test function. The lamp
test starts at the 1/4 light and cycles each remote light on and off. At the completion
of the lamp test, the remote light driver turns on the correct light(s) to show the tank
water or foam volume.
All four lights are on when the tank is full. The top light goes off as the tank starts
to empty (at 7/8 full the light is off). The three bottom lights are on to show that the
tank is between less than full (approx. 7/8 tank) and 1/2 tank. The bottom two lights
show 1/2 and 1/4 tank. The bottom light blinks when the tank volume goes less than
1/4 tank.
Buzzer
The buzzer sounds when the tank volume drops to 1/4 tank. (This is programmable.
Review the Warning and Control Level Adjustment section on page 28 for
detailed information.)

CALIBRATION
The TankVisionPro has unique calibration programs that enable it to be used on
tanks of all shapes and sizes.
Note: The standard pressure sensor is limited to a maximum tank height of
ten feet.
Overview
Magnet Sensor
The calibration programs are accessed by activating the C 1 and C 2 magnet
sensors that are located on the front of the display module. The sensor is activated by
placing the north or south pole of a small magnet in close proximity of the sensor. The
magnet is then moved about 1-inch away, this will produce an electronic signal that is
similar to a button being released. If the LEDs in the display do not change try moving
the magnet further away from the sensor.
In these procedures the term ‘swipe’ will mean to move the magnet up to and then
away from the magnetic sensor.
Non-Linear Calibration
The rst program is a non-linear calibration procedure that can be used for any shape
or size tank. This procedure must to be used for irregular shape tanks (e.g.: T-shape,
oval, elliptical, tank with through hole, etc.). The program compares the pressure in the
tank, as the tank lls at a steady rate, to time. This provides for very accurate displays.
Linear Calibration
The second program is a linear calibration procedure that can only be used when
the tank volume is proportional to the height. This would include square or rectangular
shape tanks with no irregularities. It is quick way of calibrating a tank but not as accurate
as the non-linear procedure. The program compares a full tank to an empty tank, takes
the difference and divides it into eight equal volume displays.
Full Tank Correction
This program is for use to ne tune the tank display after a non-linear or linear
calibration procedure has been completed. It would only be needed in cases where
one type of liquid is used for calibration when a different liquid would normally be in
the tank. For example this would allow the basic calibration of a foam tank to be done
using water and then the calibration would be ne tuned when the tank is lled with
foam concentrate.

WLA300 Rev170606
PROGRAMMING CODES
Code Entry
1. Swipe the magnet at C1. Each of the bottom row of LEDs turns on one at a time.
2. Swipe the magnet at C2. Each of the top row of LEDs turns on one at a time.
For example:
A. To enter Code 32, swipe the magnet at C1 three times, and then swipe the
magnet at C2 twice.
B. If the code is accepted, the display will ash with the corresponding
number of top and bottom LEDs as the entered count. For example—three
bottom row and two top row LEDs will ash alternately between the top and
bottom rows.
3. The process times out after 10 seconds of inactivity, or if no additional codes
are entered (except for the non linear calibration).
4. Save the new setting or enable new data entry by holding the magnet at C2 for
5 seconds.
Calibration and Tank Level Correction
Linear Tank Calibration
1. Start this process with a full tank.
2. Enter Code 44 to activate the Linear tank calibration. (See page 23 for detailed
step-by-step instructions.)
Nonlinear Tank Calibration
1. Start this process with an empty tank.
2. Enter Code 33 to activate the Nonlinear tank calibration. (See page 22 for
detailed step-by-step instructions.)
Level Correction and Warning
Enter Code 55 to start full level correction. Make sure the tank is almost full, or
at greater than 90%.
Enter Code 66 to activate the warning, if the signal is 0.5V higher than the full level.
Note: See page 27 for complete Diagnostics & Warnings information.

WLA300 Rev170606
Non-Linear Calibration
This non-linear calibration procedure can be used for any shape or size tank. The
calibration process requires that the tank be empty at the start of the procedure and
then lled at a steady rate of ow.
The term ‘swipe’ means to move the magnet up to and then away from the C 1
and C 2 sensors on front of the display.
Note: To exit the calibration mode without saving any new calibration, reset
the power to the display.
1. Empty the tank.
2. Apply power to the display module.
3. Swipe the magnet three times at C 1 and three times at C 2 to enter the calibration
mode. Hold the magnet at C 2 for ve seconds to activate the calibration.
Result: Top three display LEDs and bottom three LEDs ash on and off.
Note: Once the calibration process is activated the ow rate of liquid into the
tank must remain constant for the procedure to be accurate.
4. Fill the tank at a steady rate of ow.
Note: As the tank is lling up, the display will simulate a visual "ll-up"
light pattern.
5. When the tank is full stop the ow.
6. Hold the magnet at C 2 for ve seconds to set the calibration into memory.
7. After six seconds the calibration process terminates and all the LEDs are on
to show that the tank is full.
24
WLA300 Rev170606
Linear Calibration
This linear calibration procedure can only be used for square or rectangular shape
tanks with no irregularities. The calibration process requires that the tank be full at the
start of the procedure.
The term ‘swipe’ means to move the magnet up to and then away from the
C 1 or C 2 sensors on front of the display.
Note: To exit the calibration mode without saving any new calibration, reset
the power to the display.
1. Fill the tank. (Do not ll up into the ll tower.)
2. Apply power to the display module.
Note: Once the calibration program is activated there is a six second time out.
Do not wait more than six seconds to move from step 3 to step 4.
3. Swipe the magnet four times at C 1 and four times at C 2 to enter the
calibration mode. (Do not wait more than six seconds in between swipes or
the session will time out.)
Wait until the top four and bottom four display LEDs alternatively ash on
and off. (See the diagram below.)
4. While the LEDs are still ashing, hold the magnet at C 2 for ve seconds to set
the calibration into memory.
5. After a few seconds the calibration process will terminate and all the LEDs
will go on to show that the tank is full.

Full Tank Correction (Code 55)
This ne calibration procedure is used to ne tune the tank display after a
non-linear or linear calibration has been completed. The calibration process requires
that the tank be full at the start of the procedure and the display shows 75% or more.
The term ‘swipe’ means to move the magnet up to and then away from the
C 1 or C 2 sensors on front of the display.
Note: To exit the calibration mode without saving any new calibration, reset
the power to the display.
1. Fill the tank. (Do not ll up into the ll tower.)
2. Apply power to the display module.
Note: Once the calibration program is activated there is a six second time
out. Do not wait more than six seconds to move from step 3 to step 4.
3. Swipe the magnet ve times at C 1 and ve times at C 2 to enter the
calibration mode.
Result: Top and bottom ve display LEDs ash on and off.
4. After three seconds hold the magnet at C 2 for ve seconds to set the calibration
into memory.
5. After six seconds the calibration process will terminate and all the LEDs will
go on to show that the tank is full.

CLEAN/INSPECT PRESSURE/VACUUM FOAM TANK VENT
The pressure/vacuum foam tank valve is supplied for use on sealed foam tanks.
There are internal passageways that provide a path for air to move between the
tank and a center cavity in the vent. These passageways are self-draining and designed
to prevent splashing foam from entering the center cavity and clogging the pressure
and vacuum valves.
The pressure and vacuum valves are easily accessed and disassembled for periodic
cleaning or inspections. Unscrew the cap from the main body and lift the valves out
of the center cavity. Clean all parts with warm water.
Note: The internal pressure and vacuum valves are different sizes. Make sure
to reassemble these valves correctly.
Note: It is extremely
important that the pressure
and vacuum valves are
assembled correctly.
