There are mainly two reason for this problem:
2.Touch screen’s parameter adjustment or the failure of the circuit
Set Zero on the main page, and choose all hoppers, let the weigh hopper run three times continually, then come to the Read load Cell Page, observe which hopper can’t return to zero.
If some hopper can’t return to zero, which means this hopper’s installation is abnormal, or the load cell is broken, or the modular is broken.
And observe whether there is a large number of communication errors in the module of the monitoring page.
If some hopper’s door opening/closing is abnormal, it need to check whether the weigh hopper’s installation is not correct. If yes,install it again.
If all hopper can open/close the door correctly, the next step is to take down all the weigh hopper to see whether there are material on the weigh hopper’s hanging spare parts.
Last to ensure no material clutter on each weigh hopper’s spare parts, then make the calibration of all weigh hopper.
