4-3 Load cell Installation
Load Cell Wire Connection (In case of SEWHACNM’s Load cell)
It depends on the manufacturer of load cell, please check the specification.
Under Set-up the Load cell, if EXC+ and EXC- have a short circuit,
It may cause damage in the indicator.(specially analogue board)
If you connect other wires to Load cell terminal wrongly, it may cause damage
in the analogue board.
Before connecting the load cell cable you have to power off and be sure to connect
the cable to the terminal correctly.
Do not weld near the load cells , Indicators or other devices.
■Load Cell Installation
1. You can connect Max 8pcs of same capacity Load cells at once. (350 Ω)
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. If you measure static
electricity material, please make earth between down part and up part of Load cell.

5. SET-UP
5-1. Test Weight Calibration Mode (Using test weight)
5-1-1. Start Test Weight Calibration Mode
5-1-2. Setting “Capacity of weighing Scale”
If you want to set Max capacity as 1,000kg and the division is
0.1 (100g), then just input “1000”.
Remove “CAL-BOLT” on the Front panel, .
and press “CAL - LOCK S/W” inside.
When “CALIBR”displays, press key,
select “WCAL”and press key.
After displaying “CAPA”, input max capacity with keys & Press key to save &
move to next step.

SI 560A DIN SIZE WEIGHING INDICATOR
5-1-3. “Decimal Point”and “Digit / Division”Value
Max decimal point will be 0.001, and digit can be selected among 1, 2, 5, 10, 20,
50. Digit and decimal point must be fulfilled under the below condition.
(division value / Max capacity value) cannot be over 1/20,000. If this condition is not
fulfilled, “err-1”will be displayed and move back to capacity setting mode.
5-1-4. Measuring the “DEAD”Weight of Weighing Scale.
After “DIVI”is displayed, locate decimal point with key and key. Set the
division with key and key, save key to save.
When “DEAD”displays, Press key, then indicator will calculate dead weight of
scale part automatically (While this process, there should be nothing on the scale part.)

- 14 -
SI 560A DIN SIZE WEIGHING INDICATOR
In this step, if there is unstable condition such as some forces or Vibration on the
scale part, “ErrorA”will be displayed, and “DEAD value”will not be calculated.
Please remove the cause of the force or vibration and process it again.
5-1-5. Calculating span value
Indicator will search “DEAE weight”during 10secs automatically to find the best
condition.
If the count is over, input the weight of your “Test Weight”and press key.
If “UP”is displayed, please load “Test Weight”on the scale part and press
key.

- 15 -
SI 560A DIN SIZE WEIGHING INDICATOR
After calculation, span value will be
displayed on the display. Then press
key.
When “CALEND”is displayed and
calibration is completed.
Calculate Span value during 10~20 secs.

- 16 -
SI 560A DIN SIZE WEIGHING INDICATOR
5-2. Simulation Calibration Mode(Calibrate without Test weight)
With this “Simulation Calibration Mode”you can make simple calibration without any
“TEST weight”This calibration mode uses “Load cells’max capacity”and “Max Output
Rate(mV)”, so the weight adjustment degree might be less than “Test weight Calibration”.
The guaranteed resolution of this “Simulation Calibration”is 1/3,000.
5-2-1. Simulation Calibration Mode Start
Remove “CAL-BOLT” on the Front panel,
and press “CAL - LOCK S/W” inside.
When “CALIBR”is displayed, press
key and select “SCAL”.
Press key to enter to simulation
calibration mode.

SI 560A DIN SIZE WEIGHING INDICATOR
5-2-2. Setting “Capacity of Load Cell”
In case of multiple pieces of load cells are installed, Please 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 capacity is1,000kg.
Then, total Max Capacity will be 4,000kg(1,000 x 4) and you have to input 4,000.
5-2-3. Setting “Digit / Division”value
After “CAPA”displayed, Check Max Capacity of Load cell.
(refer the load cell label, or Test Report)
Input the Max Capacity of Load cell. And press key.
After “DIVI”is displayed select Decimal point with and key, and set the
division with and key. Press key to save.

SI 560A DIN SIZE WEIGHING INDICATOR
5-2-4. Measuring the “DEAD Weight”of Weighing Scale.
5-2-5. Inputting Max Output ( Rated Output Voltage / mV)
When “DEAD”displays, Press key, then indicator will calculate dead weight
of scale part automatically.
(While this process, there should be nothing on the scale part.)
After “mV”displayed, Check the Rated output value of Load cell.
(Refer to the load cell label, or Test Report) . And Press key to save and move to
next step.

- 19 -
SI 560A DIN SIZE WEIGHING INDICATOR
In case of multiple pieces of load cells are connected, the rated output will be
same as single load cell’s. (Because plural load cells are connected with parallel
connection, the sum of rated output voltage is same as single load cell’s rated output)
※Due to some variation between “State 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.
If input wrong value, there will display “Err-01”, please go back to Setting “Capacity of
Load Cell”. After recheck the label of load cell and retry the process.
Calculated span value will be displayed.
Then press key to finish the
calibration step.
