4-3-1. Load Cell Connector Specification
4-3-2. Load Cell Installation
1) You can connect Max 8pcs of same capacity Load cells at once. (350Ω)
2) You have to make horizontal balance on the ground.
3) If you install more than 2pcs of Load cells, use Summing box and adjust output signal difference as
minimum. It can make wrong weighing process caused by each load cell’s variation.
4) If there is some temperature difference around Load cell, it can cause wrong weight measurement.
5) Don’t do Welding job or Arc discharge around installation place. But, there is no choice, please
disconnect power cable and Load cell cable.
6) If you measure static electricity material, please make earth between down part and up part of Load
cell.

This “SI 4100” weighing controller’s Max input sensitivity is 0.2㎶/ Digit.
And for precise weighing system, the following formula must be satisfied.
Caution : “Input sensitivity” means Min. output voltage variation of weighing part to change 1digit.
So, please do not make large input voltage to make reliable weighing system.

Load cell capacity : 500kg
Load cell Related output : 2mV/V
Division : 0.05kg
Affirmation Voltage of Load cell : 5,000mV
Max Capacity of Weighing System : 300kg
Then, estimation result for this weighing system with formula,

5. SET-UP
5-1. Calibration
Calibration is the process of adjusting weight balance between “Real weight” on the load cell and
“Displayed weight of Indicator”. When you replace LOAD CELL or Indicator, you have to do Calibration
process once again
5-2. Test Weight Calibration Mode (Using Test weight)
Prepare the test weight as at least 10% of your weighing scale’s max capacity.
Remove “CAL-BOLT” on the indicator’s front panel and press “CAL - LOCK S/W” inside.
※Remark: If “P-W”is displayed, you should input the pass word to start calibration mode.
1. At normal mode, remove “CAL-BOLT” on the Front panel
123
2. And press “CAL - LOCK S/W” inside.
Check the “SET-CAL. message on display.

Please remove the test weight from weigh bridge.
0.629238
※Caution : The “Test Weight’s value” must be at least 10% Max capacity of weighing scale.
“at least 10%” means to guarantee precise weighing process you have to make standard with at least
10% of the max capacity weight.
We programmed the calibration will not be done, when you load less than 10% of the max capacity.
17. Press key to save all calibration process.
After then it resets automatically.
Now, fasten the Calibration Bolt on the front panel.

5-3. Simulation Calibration Mode (Calibrate without Test weight)
Through this “Simulation Calibration Mode” you can do simple calibration process without Test weight.
This calibration mode uses “Load cells’ max capacity” and “Rated output value(mV)”.
Simulation calibration’s degree of accuracy is lower than test weight calibration.
By simulation calibration’s characteristic, measured weight can be different with actual weight, according to
load cell’s actual output.
1. At normal mode, remove “CAL-BOLT” on the Front panel

5. After input max capacity of your load cell (at the label),
press key
Ex) Load cell CAPA: 30kg, division : 0.01 Input 3000
C 3000
In case of multiple pieces of load cells are installed, make sum of each load cell’s capacity and make setting
with max capacity. EX) There are 4pcs of load cells, and each load cell’s Max capa is1,000kg.
Then, total Max Capacitywill be 4,000kg(1,000 x 4) and you have to input 4,000.

※Caution : Due to some variation between “Stated output rate” and “Real Output rate” of load
cell, there might be some weight difference after finishing calibration.
If you want to make more precise weighing process, please measure real output rate of load cell and input the
measured value. Then the weight measurement will be more precise than before.
