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 4000” 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 Voltage : 2mV/V
Digit : 0.05kg

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)
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.
Then, you can enter the Calibration Mode with and start calibration mode with pressing
key.
Remove the CAL.Bolt.
Push the CAL. S/W Check the “SET-CAL.
Massage on display.
※For the save the each step, press key, for the cancel or move back, press key.
Step No.1 - Setting “Capacity of weighing Scale”.
Set Max. Capacity of Load cell Press “Enter” and move the next step.
Under this step, input Max. Capacity of you weighing scale.
Input Max. capacity of your weighing scale with No. keys.
The Max. capacity can not be exceed Max. capacity of load cell.
After finishing input, press key and save and move to next step.

Step No.2 - Setting “Decimal Point”
Decimal point position select with “0” key Press “Enter” and move the next step.
Under this step, define the optimal position or Decimal point.
Whenever pressing key, Decimal point will be changed, like XXX. – XX.X – X.XX - .XXX
The Max. Decimal point will be third place under Zero.
On the Optimal position, stop pressing key and press key to save and move to next
step.
Step No.3 - Setting “Digit / Division” value.
Set Digit(Division) with “0”
key.
Press “Enter” and move the next
step.
Press “Enter” and move the
next step.
Press “Enter”and move the next step.
Under this step, define the optimal Digit/Division value of weighing measurement.
Whenever pressing key, the Digit/Division value will be changed, like 01-02-05-10-50.
On the optimal Digit/Division value, stop pressing key and press key to save and
move to next step.
Caution※
(Max. capacity value / division value) can not be over 20,000.(as Indicator resolution is 1/200,00).
If the value is over 20,000, Error message “ Err 01 “ will be displayed and move back “CAPA” mode again.

DIGITAL WEIGHING INDICATOR
SI 4000

Step No.4 - Measure the “DEAD Weight of Weighing Scale.
Memorize “DEAD weight” of Weighing Machine
with “Enter”.
Indicator will search “DEAD weight” during
5sec, automatically.
Under this step, measure the “DEAD Weight of Weighing Scale”.
This “DEAD Weight” is very important to make “ZERO” value of weighing scale, so please make sure that
the weighing scale is empty and free from other external variations.
When you press key, the indicator starts to find “Zero” condition of scale during the 5sec.
After finding optimal “Zero” value, automatically move to next step.
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.
Step No.5 - Input Test Weight value and Calculate SPAN value.
Input “Test weight” capacity
Input “Test weight” capacity and
press “Enter”.
Load “Test weight” on
weighing part.
Process Span Calculation with
press “Enter”.
Indicator will calculate span
value during 5sec, automatically.
After calculation, display span
value on the display
Under this step, input prepared “Test Weight’s value” and calculate “SPAN Value”.
The “Test Weight’s value” must be at least 10% max. capacity of weighing scale.

DIGITAL WEIGHING INDICATOR
SI 4000
20
Input prepared Test weight value and press key, then message will be
displayed.
Then load Test weight on weighing scale and press key.
Then, indicator will make adjustment for “Standard weight value” and calculate “Span value”.
※“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.
Caution※
In case of Max. load cell capacity value /Division value is under 5,000, please prepare Standard weight at
least 10% of Max. load cell capacity value or max. display capacity value and set.
In case of Max. load cell capacity value / Division value is over 5,000, please prepare Standard weight at
least 20% of Max. load cell capacity value or Max. display capacity value and set.
This will be make more accuracy calibration setting.
- If you set test weight value over max. load cell capacity, Error Message “Err 04” will be displayed.
- If you set test weight value under 10% of max. load cell capacity value, Error Message “Err 05” will be
displayed.
Step No.6 – End calibration process / “CAL” switch OFF
Now, the Test weight calibration is done.
Calibration process completed. Push Calibration Lock S/W and tight Cal. Bol.
Press key to save all calibration process.
Now, Off the “CAL LCK S/W” and fasten the Calibration Bolt.
Caution※
To process “Simulation Calibration” process, All indicator has its’ own standard value of 2mV gap.
So, if you replaced analogue board, you have to input standard value of 2mv gap.
And you can check the this 2mV gap value on F96. (Normally, the gap value is between 200,00 ~400,000)
