10. Protection operation
10-1 The list for protection operation
When the soft starter occurs abnormity, the protection function runs, it trips immediately,

Some faults is related, for example, report that
over current or load short-circuit, therefore, when check the fault, please consider compr-
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.
