ACC-300 type controller is used to control the operation of ACG air-operated pump. Signals from top/bottom limit sensor built-in a pump automatically control the solenoid valve to reciprocate the pump.
By pressing Operation button,Output becomes ON, which indicates solenoid valve is ON, and the pump cylinder rises. When S2 switch is ON at the upper limit position, Output becomes OFF and the pump cylinder moves down. Grease is discharged from the pump by the repetition of this cycle.
