Some faults is related, for example, report that

ehensively, to judge the faults accurately.

Notice:

When soft starter starts motor successfully, the indication lamp for running in the middle

of panel lightens, it says that the it runs at the bypass, if the bypass contactor can't absorb,

it will cause the motor stops running, thus, you shall check the bypass contactor and con-

nection.
