The GrowerSELECT® HS589 Control Unit Switch Assembly is designed as a replacement switch assembly for the HS593 control unit. It can also be used as a direct replacement for other OEM control unit applications. The HS589 is designed for flexible auger feed systems where control of the auger drive motor is required.
Power to the auger drive motor is controlled through feed pressure being applied to a diaphragm coupled to an electrical switch internal to the control unit housing. The switch is used to control the auger drive motor by turning off the power when feed is present and turning on the power when feed has been removed from the control unit housing.
Alternate, not replacement for AP® part number: FLX-4512 The sensitivity of the electrical switch is not adjustable.
MAXIMUM LOAD RATING: 1-1/2 HP @ 230VACA red indicator light on the side of the switch housing will illuminate when diaphragm has been pressed (MOTOR OFF) and the switch has been activated.
