2. The measured value does not increase or does not match the expectation: This problem may be caused by incorrect voltage measurement. In this case, it is recommended to check whether the measured voltage matches the rated parameters of the equipment.

3、Motor protectorThe relay does not work. The possible reason is that the relay does not receive the control command. The solution is to check whether the communication link is correct.

4、Motor protectorUnable to enter parameter settings. The possible cause of this problem is that the password entered for the low-voltage motor protector is incorrect. In this case, it is recommended to contact the sales or company after-sales service department to resolve the issue.
