(1) the software should first detect whether the sensors are normal in each position. If the sensor is open or broken as a position detection, no signal is received in the unit time, then the machine is stopped and the alarm is started, thus improving the reliability of the equipment.

(2) when the baling machine detects the tip, it indicates that a tape will be used up. The machine is automatically pulled out, then the alarm is told that the tape has been used and a new tape is needed to be reinstalled.

(3) when entering the belt, if the defect of the belt causes it to be stuck in the banding machine, the binding function detects that the tape is defective.

As a financial instrument, security is also an important indicator. So it requires some special cases, such as when the coinage motor is just starting to loosen the coin. The sensor of the coin-operated motor suddenly broke down. If the abnormal conditions are handled normally, the coinage motor will stop and report to the police. The cash will be pressed into the equipment and the maintenance personnel will be on site for a day or two. But putting cash outside is not allowed by the financial sector. The method for handling this abnormal condition is to press a button for a few seconds, and the coinage motor is the loose currency until the key is released.

In addition, for each individual action, each individual action can be completed by pressing the corresponding button on the panel. Through this design, it is easy to repair the machine.
