The 02 error code usually indicates that the packet received by the vibration disk controller is not in the correct format. This is usually due to a mismatch in communication protocols or incorrectly formatted data being sent.
If you are experiencing an 02 error code, there are several things you can try:
Check that the communication protocols match to make sure that the packets are being sent in the correct format.
Check if the connection line is normal, make sure the connection between the vibration plate controller and other devices is stable.
Restart the vibrating tray controller, sometimes this can solve the communication problem.
If none of the above methods work, you can refer to the documentation of the vibration disk controller or contact the manufacturer's customer service for help.
