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.

Caution

4-2-4. Formula to plan the precise weighing system

This “SI 4200” weighing controller’s Max. input sensitivity is 0.1㎶ / 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.

Example1.)

The number of Load cell : 1pcs Load cell capacity : 500kg

Digital Weighing Indicator

SI 4200

Load cell Rated 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,

Example2.)

The number of Load cell : 4pcs Load cell capacity : 500kg Load cell Rated output : 2mV/V Division : 0.10kg Affirmation Voltage of Load cell : 5,000mV Max. Capacity of Weighing System : 1,000kg

Then, estimation result for this weighing system with formula,

※ According to “Resolution” or “Capacity”, it might not be calibrated like calculation.

4. Please input Max capacity of your weighing scale,

And press key. Ex) Load cell CAPA : 20kg, division : 0.001  Input 20000

C 20000

5. define the optimal position or Decimal point

Whenever pressing key, Decimal point will be changed. Ex) Load Cell CAPA : 20kg, division : 0.001kg  input 20.000

5. SET-UP

5-1. Calibration

Adjust weight balance between “Real weight” on the load cell(Weight Part) 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)

※remarks : In case that “P-W” is displayed, you have to check the pass word.

Prepare At least 10% of Max. capacity of your weighing scale, and remove “CAL-BOLT” on the Front panel and press “CAL - LOCK S/W” inside.

※remarks : In case that “P-W” is displayed, you have input the pass word to start

calibration mode.

7. Define the optimal Digit/Division value of weighing measurement.

Whenever pressing key, the Digit/Division value will be changed like 1->2->5->10->20->50.

Ex) Load cell CAPA : 20kg, division : 0.001 Input division “1”

8. press key to save the Digit/Division value and move to next step

d 1

※ Caution : (Max. capacity value / division value) cannot be over 20,000.(as Indicator resolution is 1/20,000). If the value is over 20,000, Error message “ Err 01 “ will be displayed and move back “CAPA” mode again.

9. When you press key, the indicator starts to find “Zero” span..

10. Indicator will search “DEAD weight” during 5sec, automatically. After finding optimal “Zero” span , step is automatically

Moves to next.

Cal-1 0

※ Caution : At this step, if there some force or Vibration on Weighing scale, and unstable condition will be

continued, “ErrorA” will be display, and “DEAD value” will not be calculated. Under this condition, please remove force or vibration and process it again.

11. Span Calibration mode starts..

12. Input “Test weight” capacity. And press key. Ex) Load Cell CAPA : 20kg, division 0.001

 Use test weight(at least 2kg) which is 10% of max CAPA(20kg)  input test weight 2.000

l 2.000

13. After displaying “UP” ,please load “Test Weight” .

Ex) Load Cell CAPA : 20kg, division 0.001

 Use test weight(at least 2kg) which is 10% of max CAPA(20kg)

14. And press key.(Do not unload test weight)

15. Indicator will calculate span value during 5sec, automatically

Cal-2 0

16. After calculation, span value displays on the display. Please unload the test weight.

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 weight of Max. capacity.

We programmed the calibration will not be done, when you load less than 10% of max. capacity.

17. Press key to save all calibration process. After then it resets automatically. (Now, fasten the Calibration Bolt. )
