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.

4-3-3. Formula to plan the precise weighing system
This “SI 4300” weighing controller’s Max input sensitivity is 0.2㎶ / Digit.
And for precise weighing system, the following formula must be satisfied.
!
Caution
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.
Single Load cell use
EⅹBⅹD
A : Load cell capacity(kg)
A
B : Load cell Voltage(mV)
0.2㎶ ≤
EⅹBⅹD
Plural Load cells use
D : Digit
E : affirmation Voltage of Load cell
0.2㎶ ≤
AⅹN
N : Number of Load cell
Example1.)
Number of Load cell : 1pcs
Load cell capacity : 500kg
Load cell Voltage : 2mV/V
Digit : 0.05kg
Affirmation Voltage of Load cell : 5,000mV
Max Capacity of Weighing System : 300kg
Then, estimation result for this weighing system with formula,
5000ⅹ2ⅹ0.05
= 1 ≥ 0.2㎶
500
The calculated value is larger than 0.2㎶, so this
system has no problem.
Example2.)
Number of Load cell : 4pcs
Load cell capacity : 500kg
Load cell Voltage : 2mV/V
Digit : 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,
5000ⅹ2ⅹ0.10
= 0.5 ≥ 0.2㎶
500ⅹ4
The calculated value is larger than 0.2㎶, so
this system has no problem.
※ According to “Resolution” or “Capacity”, it might not be calibrated like calculation.

6-2. Current Loop Interface
“Current Loop” Interface is stronger for Electric Noise than “RS-232C” interface.
So, it can be used for long distance communication.(About 100m long distance).
※ Current Loop Interface supports, up to 9,600 Communication Speed, only.

This Print Interface Option is based on “Centronics Parallel Interface”, so this print interface can be
connected other printers using this communication method.
But, the print format is programmed based on our “SE7300”, and “SE7320” Industrial Printers, so you had
better to use these printer for convenience.

6-4. Analog Output Interface (Option 02 : 0~10V Output)
This Option card converts weight value to Analog Voltage output(0~10V) and transfers to external
devices(Recorder, P.L.C), controlled by voltage output.
6-4-1. Specification
① Output Voltage : 0~10V DC output
② Accuracy : More than 1/1,000
6-4-2. Circuit
※ This Voltage output is proportioned on weight calibration and outputs 0~10V.
6-4-3. Output Adjustment
①This output is adjusted as when the weight is “Zero”, output is 0V and When the weight is “Full
capacity”, output is 10V.
②If you need additional adjustment, please adjust with “VR1(Zero)”, “VR2(Span) on the Analog Output
PCB.
※ Remark
This Analog option card converts Displayed weight value(Micro-process data) to analog value on
D/A Converter(Digital to Analog converter)
This D/A Converter has Max 1/4,000 accuracy, so this output is not suitable for high accuracy
application, like more than 1/3,000.

 How to Calculate Check sum.
Sum the value from “STX” to “ETX” and converts to ASCII(2byte) and transfer.
Convert the Sum value(HEX) to ASCII and transmit(28byte) .
ex) The sum HEX value from STX to ETX(02,30,31,52,43,57,54,03) is 1A6h.
Then, divide 1A6h by 100h(1A6h/100h). the rest of result is A6h.
Calculated remainder value is A6h, then convert A6h to ASCII, 41(A), 36(6), and transfer.
