1. Touch screen calibration
A. Click the middle position of the touch screen to enter the calibration mode within 3 seconds after starting the machine. Click the corresponding position of the screen according to the prompts, and restart the machine after calibration.
2. Debugging meter meter and frequency converter
A. Set the traction frequency converter to the external voltage (0V-10V) for input control.
B. Make the Mike weight controller of the film blowing machine under manual control, and power up the traction frequency converter.
C. In the parameter setting function, set the parameter of "Inverter Manual" to 5Hz, and save to exit.
D. Observe the "actual speed" on the LCD screen. The speed should be stable and the observation time should not be less than 30 seconds.
E. Observe the frequency display on the traction frequency converter. This frequency should be different from the set parameter of "manual frequency converter"
The observation time should not be less than 30 seconds after 3Hz and the observation time is stable
F. Set "Frequency Converter Manual" parameters to 10, 30 and 50Hz respectively; Repeat steps C, D and E.
3. Calibration of electronic scale
A. Press the "Calibration Electronic Scale" button in the kinetic energy of "Parameter Setting" to enter the calibration function of electronic scale.
B. Empty the material in the hopper, and then press "OK" to connect the button.
C. Put accurate weights in the hopper. It is recommended to put 3000-gram weights in the hopper, and then input the actual weights
And press the "OK" button to complete the calibration of the electronic scale.
D. Press "Exit" to return to the main screen. At this time, the weight of the hopper should display 1.000kg.
E, take out 3000 grams of weight, put 1000 grams of weight, at this time the hopper weight should be displayed as 1.000kg, if the display is not correct, please recalibrate.
4. Automatic feeding and sound and light alarm test
A. Set the low level of the hopper to 0.5kg and the high level of the hopper to 2.5kg.
B. Empty the hopper. At this time, there should be an acousto-optic alarm for lack of material in the hopper. At the same time, the feeding baffle above the hopper is opened and in the feeding state.
C. Apply downward pressure of more than 2.5kg on the hopper by hand, then the feeding baffle above the hopper is closed, indicating that automatic feeding is normal.
5. At the end of debugging, the Mike weight controller of the film blowing machine can work normally.
