<P>PROBLEM TO BE SOLVED: To provide a pump set having a safe interlocking device for judging a state that the pump set is surely mounted on a pump. <P>SOLUTION: A supplying set 5 has a conduit 55 for a nutrient solution and the safe interlocking device 61 connected to the conduit. A pump apparatus has a pump device and a controlling system for controlling the operation of the pump. An electromagnetic radiation source is connected to the controlling system of the pump in an operable manner in order to radiate an electromagnetic radiation signal toward the safe interlocking device of the supplying set. The safe interlocking device 61 is constituted so as to exert an effect in an electromagnetic radiation direction. An electromagnetic radiation detector is connected to the controlling system in an operable manner and receives the electromagnetic radiation signal in a case that the direction of the electromagnetic radiation signal is affected by the safe interlocking device to issue a command for the controlling system to confirm a state that the conduit of the supplying set is appropriately arranged to a supplying pump. <P>COPYRIGHT: (C)2007,JPO&INPIT |
