Analysis：When parallel or connecting to ATS, the communication resistance value is incorrect or the wiring is incorrect. In the case of parallel operation, the parallel address settings are duplicated.

Solution：Check if the wiring of the CANB interface is correct. In the event of a power outage, the normal communication resistance range for measuring the resistance value of CANB should be 60-120 ohms. The communication resistance value can be changed by adjusting the CANB DIP switch on the control board. In the case of parallel operation, set the parallel addresses in order based on the number of parallel operations, from 1 to 4.

Analysis：It is usually caused by pressing the emergency stop button.

Solution：Reset the emergency stop button. If it cannot be resolved, please contact after-sales personnel for handling.
