Chapter 1 Overview
1.2 Definition of Terms
1.2.1 Load cell
As a load sensor that converts weight into an electrical signal, it measures the weight converted into the
electrical signal by measuring the strain in the load cell.
1.2.2 Sensitivity(㎷/V)
Load cell output voltage (㎷) per load cell applied voltage(V)
1.2.3 Remote sensing method
Load cell voltage error due to the ap plied vo ltage is caused b y a change in th e cable resista nce value r esulting
from temperature chan ges. If two remote sensor signals (SEN+,SEN-) are connected to the volta ge applicati on
device (module), the applied voltage value can be stabilized.
1.2.4 Rated load
It refers to the maximum load that c an applied to the load c ell, and is represente d as Emax = 500kg, m eaning
the maximum weight value that can be measured by the load cell.
1.2.5 Gain drift
It refers to a gain variation cause by the temperature.
1.2.6 Zero drift
It is defined as a zero variation caused by the temper atur e.
1.2.7 Gross weight
It refers to the value of the total weight applied to the load cell, including tare w eight of containers, structu res
and contents.
1.2.8 Net weight
It refers to the net weight value of the contents calculated by removing the tare weight from the total weight.
1.2.9 Maximum weight
It refers to the maximum weight value to be applied to the system within the range of the load cell rated load.
1.2.10 Standard weight
It refers to the sta ndard weight value to be applied when the user performs a calibration oper ation within the
maximum weight range.
1.2.11 Free fall compensation
It is an algorithm that c ompensates the difference between t he actual set weight value and the weight value
contained in a package due to the free fall that occurs when an object is put into a device such as a hopper.
1.2.12 Span calibration
In general, a scale performs a calibration by measuring the zero and span between the minimum and maximum
weight values (calibration range).
That is, input X t o o bta in B f r om Y= AX + B( Y: output, X: input, A: slope, B (offset)) is zero, and inp ut X t o o btain

2) Relationship between Load Cell Output and Input Sensitivity
If the load cell sensitivity is 2.0 ㎷/V, the input sensitivity of the product is 0.25uV/digit or above.
When designing the system, the following formula must be met.
Example) Number of load cells: 4
Rated load cell capacity: 500 kg:
Rated load cell output: 2mV/V
Single scale: 0.10 kg
Power connected to load cell: 5V (= 5,000 mV)
According to the formula, (5000 mV* 2mV * 0.1Kg)/(500Kg * 4) = 0.5≥ 0.25 ㎶
Since the calculated value is larger than 0.25 ㎶, the weight system design is acceptable.

Chapter 3 Installation and Wiring
3.1 Installation
3.1.1 Installation environment and suggestions
Please not the following items to ensure the reliability and stability of the system.
1) Environmental conditions
(1) Installed on the waterproof and dust resistant control panel.
(2) Protected from continuous impact (shock) and vibration.
(3) Not exposed to direct sunlight.
(4) Where there is no dew condensation caused by rapid changes in temperature.
(5) Where the temperature is kept at 0 -55℃
2) Installation
(1) Make sure that wiring waste does not go into the PLC when dr i lling and wir ing operations are conducted.
(2) Installed in a location that is good for manipulation.
(3) Not installed in the same panel with high voltage equipment.
(4) The distance between duct and surrounding modules should be kept at least more than 50 ㎜ away.
(5) Grounded in a place with favorable ambient noise environment.
(6) Installed so that wind from a cooling fan will not come in direct contact with the inside of the panel.
3) Handling precautions
(1) Handling precautions from the opening of the module and its installation are described.
(2) Do not drop or apply strong impact.
(3) Do not remove PCB from the case. This may cause a failure.
(4) Make sure that foreign matters such as wiring waste do not go into the upper part of the module in
distributing wires.
(5) Do not install or remove of the module when the power is turned on.
Chapter 3 Installation and Wiring
3.1.2 Wiring
1) Wiring precautions
(1) Do not leave AC power line close to the external input signal line of the module. It should maintain
enough distance to avoid effects from the induction noise or surge occurring from the AC side.
(2) The wires should be selected in consideration of the ambient temperature and allowable current, and the
wire specifications are as follows.
(3) Use a shielded cable to connect the load cell. Disconnect the wire from high-noise voltages or AC power
wires using a shielded cable.
(4) If the wire is too close to hot device or material or comes in direct contact with oil for a long time, it can
make a short cut and therefore lead to damage or malfunction.
(5) Check the polarity when wiring terminal blocks.
(6) If the wire is distributed along with high voltage line and power line, it causes a induction failure, thereby
contributing to malfunction or failure.
(7) Be sure to use the same power supply as that of XGB basic unit for the external DC24V power wiring.
If the external DC24V power of the module is Off/On when the XGB basic unit power is On, it can cause
abnormalities in the temperature input value.

1) 6 lines type load cell
6 lines type connection method is recommended for analog input terminals of the load cell input module. The 6
lines type can com pens ate f or ex ternal c hanges s uch as changes in line resistanc e since EXC+/- si gnal is fed
back to SEN+/- sign al f rom the load c el l. I t can further decrease errors than 4 line s t ype if a long c able is us ed.
The figure below shows an example of wiring for 6 lines type.
2) 4 lines type load cell
4 lines type has no sense output. In case of using 4 lines type, EXC+/- should be connected to SEN+/-.
The figure below shows an example of wiring for 4 lines type system.

Remark
the zero tracking func tion will adjust the weight valu e to 0.When placing a light object, set the zero
tracking setting range at 0 to measure the weight value of the object, then set the zero tracking
setting range at a value less than the weight of the object.
Example) If the maximum weight is calibrated at 100g, and a single scale is 1g, and the zero
tracking range is set at 10 and the zero tracking time is set at 30, a 5-g object on the pallet will show
up as weighing 0.In such case, set the zero setting range at 3 or below.

When resetting the displa yed weight to zero, you can perform the setting within the near zero setting range.
Near zero can be set a t 1 ~ 99% of the maximum weight. If th e gross weight exce eds th e n ear zero s ett ing r a nge,

6.1.9 Free Fall Compensation function
When the weigh m ode is supply (simple com parison, sequential com parison) and disc harge (simple comparis on,
sequential comparison), it compensates the free fall value before reaching the final setting weight value. The
following sections show an actual example of application.
1) System Composition Example
(1) If a near zero signal is detected, perform tare setting to remove the tare weight.
(2) Open the supply valve to begin raw material supply from the raw material tank to the weighing tank.
(3) When the weight reaches the final set value – step 1, the step 1 signal is out put. Using this signal, the supply
valve is closed by half.
(4) When the weight reaches the f inal set value - step 2, the step 2 s ignal is output. Using this signa l, the supply
valve is closed by more than half.
(5) When the weight reaches the final set value - free fall, the step 3 signal is output, and the supply valve is
completely closed.
(6) When the supply valve i s complete closed, the remaining r a w m ater ia l (f r ee f all) in th e r a w m ater ial tank and the
weighing tank flo ws into the weighing tank . If the final weight add ed with the infl ow amount satisfies the s tability
condition, weighing is complete and the final discharge valve is open. .
(7) Close the discharge valve after discharging the raw material, confirm that the discharge is complete by
detecting near zero signals, and then repeat steps (1) through (6).

2) Free Fall Compensation
It compensates free fall values. The following sections show an actual example.
[Set Value]
Final set values 20000, free fall compensation value (counts):4 times, free fall compensation factor:2/4, free
fall initial value:500
[Description]
1 (after connecting
When the input free fall compensation value (count) is 4, free fall is compensated if the average value of 4
weighed values is the same as or above the final set value.
·For the first 4 measurements, the measured values are adjusted by 30 by applying a factor of 2/4, as the
weight over value is 60.
·For the following 4 measurements, the measured values are adjusted by 5 by applying a factor of 2/4, as the
weight over value is 10.
·For the following 4 measurements, the measured values are adjusted by -3 by applying a factor of 2/4, as the
weight lack value is -5.
This function calculates the average weight corresponding to the set counts, and increases the free fall value
when the weight exceeds the final set value , and decreases the free fall value when the weight is less than the
target value.

4) In the setting window, set Channel 0 as running and enable simple weighing.
5) In the setting window, set Channel 1 as running and enable simple weighing.
6) Weight Measurement Program example
(1) If the module is running normally and there is no error in Channel 0, M00000 is on.
U01.00.0(Module Error) = Off
U01.00.F(Module Ready) = On
U01.01.0(Input Channel 0 in Operation) = On
U01.01.E(Input Channel 0 Error) = Off
(2) When M00000 is On, the weight value (U01.06) of Channel 0 is moved to D00000.

7.2.4. Using PUT/GET Command
1) Input Program Example
(1) Use the PUT command to write '3' in the Address 0 of Slot 1 to operate Channel 0 and Channel1.
(2) Use the GET command to store the zero tracking range of Slot 1 to D00900.
(3) Use the PUT command to input '7' in Address 9 of Slot 1 to set the moving average value at 7.
(4) If the module is runing normally and there is no error in Channel 0, M00000 is on.
U01.00.0(Module Error) = Off
U01.00.F(Module Ready) = On
U01.01.0(Input Channel 0 in Operation) = On
U01.01.E(Input Channel 0 Error) = Off
(5) When M00001 is on, the weight value (U01.06) of Channel 0 is moved to D00000.
(6) If the module is running normally and there is no error in Channel 1, M00001 is on.
U01.00.0(Module Error) = Off
U01.00.F(Module Ready) = On
U01.01.1(Input Channel 0 in Operation) = On
U01.01.F(Input Channel 0 Error) = Off
(7) When M00001 is On, the weight value (U01.08) of Channel 0 is moved to D000002.
