1.1.1 Mechanical part
1．The servo driver is used as the motor driving device to ensure the stability and
adjustability of the speed in the process of weight checking.
2. Double photoelectric mode more accurately determine the object up and down the
weighing platform, improve the accuracy and efficiency of weight detection.
3. Scale height adjustment range is larger, convenient for customers to choose to use.
4. Mechanical modular design makes transportation and maintenance more convenient
and application adaptability stronger.
1.1.2 Electrical part
1. Simple wiring, external only need to access the power cord; The internal use of
different specifications pin plug terminal block, wiring is convenient and will not make
mistakes.
2. Touch screen operation interface optimization, product parameter setting is simple
and the main interface content is richer.
3. The three-color indicator shows qualified (green), out-of-tolerance (red), under
tolerance (yellow), and the working state of the inspection weight is clear at a glance.
Buzzer user can define the alarm mode.
4. The new algorithm is adopted in the process of weight inspection, and the high
precision can be guaranteed in the process of high-speed weighing.
5. Optimize user login and logout function, without tedious operation and effectively
prevent others from disoperation.
1.2 Usage Notice
1.2.1 Precautions
1. Do not perform mechanical or electrical maintenance while live, do not place tools on
the scale, and do not perform welding operations on the scale.
2. The installation site must ensure the ground level, after installation through the
foundation adjustment, ensure that the weighing table level, tilt does not exceed 0.5
degrees, away from the vibration source.
3. Make sure the equipment is safely grounded and there is no strong electricity or
magnetic field interference nearby.
4. Do a good job of fire prevention, avoid direct sunlight to check the weighing table and
relatively strong air flow (outdoor air, fan and air conditioning outlet is directly against
the weighing table).
5.Should avoid squeezing, stepping on the scale platform, handling should first fixed
scale, installed sensor limit to prevent damage to the sensor, prohibit the direct handling
of the scale platform to move.

2.2 Mechanical installation
Place the checkweigher at the installation place and remove the sensor protection
device; Adjust the levelness of the checkweigher, and the inclination shall not exceed 0.5
degree; Fix the footing of the checkweigher, the stainless steel footing contacts the ground
smoothly, and lock the screws of the footing to ensure the stability of the checkweigher.
Adjust the distance between the check weighing platform and the front and rear end
conveying mechanism is 9 ~ 11mm, and the check weighing platform shall not be in
contact with other equipment. If the front and back end conveying mechanism is not equal
to the height, it is necessary to add the oblique conveying mechanism on one side, and add
the horizontal conveying mechanism connection on the side of the oblique mechanism (to
leave a gap) to check the weight scale platform, to ensure that the check weight scale
platform level and the height of the front and back end conveying mechanism.

The electric control box can be arbitrarily installed on the left and right sides of the
checkweigher to facilitate the operation of the production process.
2.3 Electrical installation
The power supply is inserted into the three-hole socket with ground or connected to
the power supply equipment such as the electric gas cabinet according to the line mark.
Any wiring and disconnecting operation can only be carried out after power off. After
the operation is completed, check before power on.
2. The serial port is fixed to RS485 communication, where the 485(A) pair should be
connected to 485(A) or 485(+), and the 485(B) pair should be connected to 485(B) or
485(-).
3. The switching quantity input point is valid at low level (DC0V) and does not allow
access to high voltage or alternating current.
4. Switching quantity output point access relay coil for intermediate control, so the
other end of the relay can access DC or AC power supply switching quantity.

3.3 Basic operation
The main interface of weight inspection is used for daily production, which is used to
start and stop the weight inspection belt, enter the relevant parameter interface and
display the basic information of the tested product and the weight inspection result.
3.3.1 Power-on operation
Power on and turn the knob switch to the "1" position. The power-on touch screen of
the electric cabinet displays the initialization interface. At the top of the interface are USB
insert mark, check scale model and time display; The black display area is the name of the
current production inspection product, the weight display area, the weight unit display area
and the weight check scale status display area; In the middle is the current setting of
weight checking speed, the current actual weight checking speed and the display statistics
of weight checking results; At the bottom are the function keys of the operation of the
weight check scale and the parameters related to the weight check.
Correct time parameters can effectively help users check the production inspection results,
relevant production parameter changes and alarm information, help to improve the
production pass rate and production speed and reduce production consumption.
The weight display area of the checkweigher displays the real-time weight value in the
stopped state, and displays the weight test result in the running state until the next
object is effective.

parameters.
2. Click this button to enter the parameter setting interface.
3. Click this button to enter the data interface to view the relevant check data.
4. Click this button to clear zero.
5. Click this button for user management operations.
6. Click this button to start and stop the device.
7. Click this type of action box to modify the value of this item.
8. Click the action box to modify the value of this item.
9. Click this type of action box to select Settings for this definition.
10. Click this type of action box to perform the corresponding operation.
11. Click this type of action box to open and close the corresponding function Settings.
3.3.2 Zero clear operation
If the touch screen displays the real-time weight value of the checkweigher in the
stopped state is not zero (zero indicates the off state), click "Clear zero" to clear the
weighing platform, so that the real-time weight value is displayed as zero, and then the
zero indicates the on state.(It can be operated only in the stopped state).
If the weight check scale shows that the weight is unchanged, the stable identifier bit
is on; otherwise, the stable identifier bit is off (the stable identifier bit is only related to the
weight state, and has nothing to do with the operation of the checkweigher and the size of
the weight value).
3.3.3 Start up operation
Click "Start" on the touch screen to start the weight checking scale, and the weight
checking motor drives the weight checking belt to rotate. At this time, the operation label
on the touch screen is "Running", and the weight checking operation can start.
