Grain electronic packaging scale failure and treatment method

Grain electronic packaging scale fault phenomenon and treatment method

1. Adjustment of speed and accuracy

In all the failures of electronic packaging scales, the adjustment of speed and accuracy is the most common problem. In the packaging of the finished product, both the speed of the packaging and the accuracy of the packaging must be ensured. This requires setting values ​​in the parameters of the instrument. For specific adjustment methods, please refer to the instruction manual of grain electronic packaging scales.

2. After the bag door is closed, it will automatically open again

When the finished product falls into the bag, the bag door should be automatically closed to release the bag, and then once again toggle the bag switch, open the bag door to open the next bag, if the bag door is closed automatically, Immediately and automatically, it indicates that there is a problem with the bag switch. Due to environmental influences, the dust in the finished product falls into the interior of the bag switch, which not only causes a certain degree of corrosion, but also causes a short circuit inside the switch. The above phenomenon occurs. After cleaning the internal dust, the malfunction can be eliminated. In order to avoid the occurrence of the above phenomenon, the bag-seal switch should be sealed and protected to prevent the dust from falling into the interior. This can not only ensure the service life of the bag switch, but also guarantee the continuity and stability of the production.

3. Press the scale start button, the material door will not open

After pressing the scale start button, the large and small material doors cannot be opened and the material cannot be fed, and the word “Err3” flashes on the F701 meter. The reason for this phenomenon is that because the scale is not used for a long time, the hopper still has a certain amount of finished products, and the value of the finished product weight exceeds the value set in F701 meter mode 36, resulting in the occurrence of this phenomenon. The processing method is to first clear the hopper, and then clear the value in the F701 meter mode 90 to solve. In order to avoid this phenomenon, it is necessary to clear the hopper in a timely manner without using the packing scale for a long time to keep the empty state. There is also a failure phenomenon is that, after pressing the scale start button, one or two of the large and small material doors do not open, F701 meter display is also normal, this phenomenon occurs, after careful inspection found that its control valve solenoid valve There is a problem with the power supply. This is because the dust in the finished product corrodes its terminals and causes poor contact with the power supply line of the solenoid valve. The problem is solved after the wiring is processed again.
