The machine keeps showing that the door is open. First, check the following three positions.

As shown in Figure 1, the emergency stop button indicated by the red arrow on the human-machine interface. Rotate the button in the direction of the arrow on it until it reaches its end, keeping it in a pop-up state.

As shown in Figure 2, after opening the main door of the machine, press the emergency stop button indicated by the red arrow on the left side of the jog switch box. Rotate the button in the direction of the arrow on it until it reaches its end, keeping it in a pop-up state.

As shown in Figure 3, the door switch has shifted. After closing the door, it was not pressed down and the door switch remained in the released state. Loosen the screws and readjust the position.
If the above three areas have been repeatedly checked and the fault has not been eliminated, please contact our after-sales service department.
