系统打开电源后，触摸屏自检扫描后，进入主欢迎界面如图六所示，并处于自 动工作状态7. Lighthouse instructions: (special order requirements, selection of accessories)
The lighthouse is the system status indication, above the bit shell, and the display is visible to prompt the operator to pay attention.
The red indicator is on when the temperature of the closure heater fails to reach the set temperature limit. The red indicator light is on, and when the user has a bag-holding operation, the system is in the waiting temperature rise state until the red indication is out.
When the vacuum package number reaches the set value, when there is no packaging action for a long time and exceeds the set pause time, the yellow indicator light is on, the system goes into the suspended state and turns off the heating power supply until the[pause] key is used to cancel.
When the system is in the normal operating state, the green indicator light is on and the operator can start the packaging operation. VIII. Touch screen control and main operation interface
After the system turns on the power supply, after the touch screen self-check and scan, it enters the main welcome interface as shown in figure 6, and is in a self-acting working state.
Figure VI, main boot interface
Through the main welcome interface, the operator can easily choose to enter the automatic, manual, functiоnal button selection interface.
Automatic work main interface: can display the status of each control output, so that the operator can cut the work of the control system
Status, as shown in figure 7.
Manual work main interface: can control the action of the output port by touching the button to achieve the purpose of manual operation
Parameter setting interface: some time parameters and counting parameters needed for automatic control process are used to input some time parameters and counting parameters, which is an important guarantee for the normal operation of the system. It has been set up when it leaves the factory, and the user can modify it appropriately according to the need. The parameter setting interface is shown in figure 9.
Suggestion: it is best for the user to record the normal working parameters in case the parameters are scrambled and the work is out of order.
The parameter resets the recovery.
Enter the functiоn button selection interface: all functiоns can be selected from here, as shown in Figure X.
Detection interface: the detection interface is used to detect and display the state of the detection points, which are necessary to work. When the system is not working properly, the state of the system can be judged by the state of the detection points. The switch input status interface is shown in figure 11.
A change in the color of a character’s background represents the state of its input point, such as when a station car moves to a bagged position.
The background of station 1 changes from background color to dark blue.

Section 3 Adjustment of the feeding parameters of the controller (to be operated by a professional)
When setting the parameters, the fast advance quantity is set, the advance quantity is increased in the middle, and the advance quantity is increased slowly to ensure the installation.
The speed and accuracy of the package are premised on. According to the previous definition, the time of each feeding process is determined by adding the advance quantity quickly, adding the advance quantity in the middle and adding the amount before the increase slowly. The faster the advance value is, the smaller the setting of the middle plus advance value is, the longer the packing process is, the longer the packing time is, the faster the packing speed is, but if the advance value is increased quickly, the setting of the middle plus advance value is too small, the faster the increase, and the end of the middle plus one. Due to the delay of operation of the actuator and the fact that the material between the discharge port and the metering bucket has not been measured, it is already too bad to enter the slow feeding. Therefore, in order to ensure the packaging accuracy, it is necessary to ensure a certain slow addition time. For The fast packing speed and stable packing accuracy are obtained, and the parameters are adjusted to the medium plus time, and the slow adding time can last about two seconds each. Specific adjustment method: if the adding time is too long, the setting value of the fast plus advance quantity will be reduced, on the contrary, the setting value of the fast plus advance quantity will be increased, and if the slow addition time is too long, the setting value of the middle plus advance quantity will be reduced. On the contrary, it increases the setting value of the amount of advance in China; If the slow addition time has met the requirements and the accuracy can not meet the requirements, then adjust the setting value of the slow plus advance quantity, if it is overweight, increase the setting value of the slow plus advance quantity, on the contrary, reduce the setting value of the slow plus advance quantity.
