Weigh Shark WING BMounting
We have designed our Weigh Shark WING B scale to easily mount
on the existing tube frame conveyor.
1. Remove the existing idler from the conveyor tabs.
2. Install the Weigh Shark WING B hardware using the same
mounting holes previously used by the idler.
3. Install the idler on the scale.
3.1 Install the two brackets provided under the mounted holes of the
idler with the bolts, washers and nuts provided, to be used for
calibration.
4. Route the load cell cables through the flexible conduit provided to
where the Weigh Shark integrator is mounted.
5. Mount the Shaft Encoder using the magnetic coupler on the pulley
shaft. Route the encoder cable to also be inside the conduit to the
integrator. Attach cable or chain to link to secure bracket from
turning on shaft.

Weigh Shark WING C Mounting
1. Select an idler that is away from the impact area and
will not be upside down during transportation. It is best
if there are 2 idlers before and 2 idlers after the scale
idler where no loading is taking place.
2. Remove the idler from the C-Channel. Install the
Weigh Shark scale with the scale C-Channel on the side
of the direction of travel.
1.

3. Install the idler onto the scale.
3.1 Install the two brackets provided under the mounted holes of
the idler with the bolts, washers and nuts provided, to be used for
calibration –See above picture.

4. Bolt the Speed Sensor on the scale frame.
5. Route your Load Cell and Speed Cable to the Weigh
Shark integrator.
Must use the Plastic Sleeving provided to protect wires
from Damage.
Mechanical Installation is Complete
You MUST remove your idler during
transport to prevent load cell damage.
2.

A) Perform the Auto Zero (ZERO TEST) as instructed.
B) Start the SPAN TEST. Since the WING scale is installed
inside the conveyor frame it is not possible to install
Calibration Weights during the SPAN TEST. You must
confirm or EDIT and change the IDLER SPAN distance so
we know the length of belt the scale idler supports. EXIT
after you have confirmed or edited to save.
Preferred: Do a Material Test catching material and
weighing it over a Truck Scale. Use the "Material Test"
instructions on page 12 to manually set your correct
SPAN.
Second Choice: This is the less preferred way since it is a
crude way of setting your SPAN. After you have done
the ZERO TEST you will stop the empty belt. Go to the
Misc. screen and look at the line: "Scale Weight". It
should be near 0 since we tarred off the load cell signal
from the belt and idler. With belt stopped and empty...
Place a known amount of weight DIRECTLY over the
scale idler. Your "Scale Weight" should increase by the
Calibration
3.

amount of weight you put on the belt. Use the formula
on the "Material Test" page using your weigh value as
the known (Truck Scale) and use the Belt Scale value of
what you read. Change your SPAN number so that the
scale shows the correct weight value you have on the
scale.
Calibration is Complete.
ELECTRICAL WIRING
1. Route your load cell and speed sensor cables through the special 4 hole
cable grip. Locate the load cell terminals and connect. Wire the speed
sensor cable to the indicated terminal also on the circuit board.
2. Route your power cable to the control box and run the cable though the 1
hole cord grip.
3. Wire either 110 VAC or 220 VAC single phase or 12-24 VDC to the
terminals indicated on the board. (Diagram below.).
When extending Speed Sensor or Load Cell Cables it is highly
Recommended to use a Junction Box or Soldeing of Wires with Heat Shrink
Wrap. Wire Nuts or Butt Connectors are NEVER to be used.

4. When all electrical connections are properly made, turn ON the unit at the
Power Switch on the board.

Correct Circuit Board Wiring

Our WEIGH SHARK integrator will support up to
8 Load Cells (4-pairs)
Our Standard Weigh Shark Scale is a single idler scale. It can be
converted to a Multi Idler Scale by the addition of pairs of load cell
assemblies on adjacent idlers. Multi idler scales increase accuracy by
weighing more material for a longer period of time.
The Scale Must be a Minimum 3 Idlers up from Material Drop Zone!
Converting a Single Idler Scale to a Multi Idler Scale.
Bolt additional pairs of load cell assemblies to the adjacent idler
using procedure shown on page 1.
When calibrating your scale you will be asked to enter Idler Span
Distance during the Span Test.
Let's say your idlers are on 4 foot centers:
Single Idler Scale Span = 8 feet.
Dual Idler Scale Span = 16 feet.
Triple Idler Scale Span = 24 feet.
Quad Idler Scale Span = 32 feet.
* See Following Page! *
During the Next Step of the SPAN TEST you are instructed to enter
the TOTAL value of test weights including the bar you will be using.
You must put weight on every scale idler using these guidelines

CALIBRATION
The calibration is divided into two categories.
A) ZERO Test
B) SPAN Test
The display will take you step by step through both processes and instruct you on
what is taking place during the process and what to do next.
ZERO TEST
1. The first step of calibration is to weigh your Empty Belt and Idler and tare
off the weight of the belt and the idler so the scale only weighs material on
the belt.
2. Push the arrow key located under “Calib.” to select this calibration process.
3. The main calibration screen will appear. An arrow will point to “Zero Test –
Press Enter”
4. Mark the belt or use the belt splice as your reference. Follow the
instructions on the display.
9.

5. Press the Arrow under START when your Empty Belt passes a reference
point start to measure and weigh your belt. The display will show you
information during this step. Watch your belt make one (1) revolution and
press the arrow under END after completion of this one revolution.
6. The screen will automatically change. It will show Belt Length (feet), Old
Zero Value and New Zero Value. It will instruct you to press the arrow under
APPLY. This will establish your Auto Zero value. The screen automatically
goes back to the main calibration screen.
10.

PREVIOUS FEATURE
Once you have established a Zero Number you have also established a belt
length for your conveyor. By using the PRV (previous) feature on the
screen, it will allow you to start a zero test without having to wait for your
splice or mark on the belt. Keep in mind that the belt MUST be empty and
no calibration weights or bar applied.
This feature is only used for recalibrating your zero number with your
existing belt length.
If you lose your settings for any reason, you will need to run a New Zero
Test following the instructions beginning on page 9.
11.

Span Test
1. Use the ▼arrow key located to the right of the display to move the
cursor arrow (>) down to the next line. “Span Test – Press Enter”.
2. Press ENTER
3. The screen will automatically change and instruct you to “Press
START to perform a Span Calibration.
4. Press the arrow under START to start your process.
5. The screen will change and ask you to “Verify the Idler Span”. (If
your idlers are on 4 foot centers….. you have a “Span” of 8 feet)!
6. The screen will instruct you to Press NEXT to continue or Press
EDIT to Change. The Idler Span value defaults to 8.00 feet. If you
need to change this value, press the arrow under EDIT.
7. To EDIT, press the ◄or ►Arrow keys to move the cursor to
activate the cell you wish to change.
8. Use the + and - keys to change the value up or down if required.
9. Press the arrow under EXIT to continue.
12.

10. The screen will change and ask you to “Verify the Test Weight”
value. Again you can accept the default value (100 lbs) NEXT or
select EDIT and change the value. Enter the total weight of your
test bar and weights.
- If you are going to run a material test to calibrate your scale….
- You can skip these steps……
- Press EXIT….Catch material and follow the instructions on :
NEXT PAGE…”Material Test”
13.

“MATERIAL TEST”
•We also suggest if possible that you verify the accuracy vs. a
legal for trade truck scale. Catch material and write down the
Belt Scale total and the Truck Scale total….then
a) Press ▲ under “Calib.”
b) Use ▼at right of display to bring the cursor down to the line
SPAN.
c) Press ENTER
d) You will want to Increase the SPAN if the scale was light and
Decrease the SPAN if the scale was heavy.
(Known Weight) Divided By (Wt. On Screen)
New SPAN = (Truck Scale Wt. / Belt Scale Wt.) X Old SPAN
(Multiplier you use to calculate your new SPAN number)
IE:If you wish to make the SPAN larger by 12% …. You take
your existing SPAN number x 1.12….. If you wish to make your
SPAN smaller by 12%, you take your SPAN number x .88.
e) Press ▲under EDIT. A line will appear under the last number
in the New Span: line.
f) Use the + or –buttons to change the number. Use the ◄ to
move to the next number to the left and again use the + or –
button to change that number. Continue until you have
entered in the complete number.
g) Press ▲under APPLY to accept your changes.
h) Press VIEW a couple times to go back to the default screen.
14.

Load %
The default screen (View) shows your Load %. It is important that you have a
reasonable load on the Weigh Shark scale to ensure the best opportunity for
accuracy. Ideally we would like to see about 75% Load when you are running
your normal rate. This will provide a good load cell signal and allow for additional
rate. If you find you are running under 50%, we recommend you increase your
ADC Gain. This will increase the amplification of the load cell signal to give us
more load cell signal to represent weight.
(Your ADC GAIN is set at the factory to 10).
Steps to Change ADC GAIN:
. 1) Go to SETUP
2) Arrow down to CALIBRATION SETUP
3) Press ENTER
4) Arrow up to ADC GAIN
5) Press ENTER
6) Press EDIT
7) Use the + button to increase your number to 15 or 20
Please Contact us to discuss your application.
8) Press APPLY
9) COMPLETED.
You will need to Re-Calibrate your scale.
You must do both the ZERO Test and the SPAN Test.
