There are two situations that cause the device to run up and the light is on:
1. Check if the contactor normally closed auxiliary contact of the contact state of the device A (X3-9) is connected.
2. When the power supply of the device is DC, check the positive and negative poles of the power supply and connect them according to the correct polarity.

Second, UNT-MMI-B control protection management device during the startup process reported overload analysis?
1. Check if the rated current is set correctly and set the rated current according to the nameplate of the motor.

3. Check the position of the transformer. The current contactor is connected between the molded case circuit breaker and the contactor. (If the current device is connected between the contactor and the motor, the positive transmission is normal, and the reverse relay may be phased. ).
