BALLAST SIGNAL CHECK UNIT AND TREATMENT SYSTEM FOR BALLAST WATER THEREOF

摘要

The present invention relates to a ballast signal check unit and a ballast water treatment system having the same. The ballast signal check unit according to the present invention comprises an input terminal part for inputting each of a pump signal, an inflow valve signal, and a bypass valve signal; a ballast operation signal generation part for generating a ballast operation signal if all of the pump signal and the inflow valve signal inputted in the input terminal part are on-signals and the bypass valve signal is an off-signal; and an output terminal part for outputting the ballast operation signal generated in the ballast operation signal generation part, thereby preventing a wrong operation and saving an unnecessary power loss.
