Grower Select - Model HS529 - Feed Level Control System
From Hog Feeding Systems
The HS529 Feed Level Control is a single pole, double throw switch configured so that the circuit is normally closed (Motor Runs) when there is no feed present against the paddle. The circuit is open (Motor Stops) when there is feed against the paddle. The HS529 internal switch is rated for 20 amps (Approximately 1 HP). It can be directly connected in series to control a motor with less current requirement than 20 amps. If the motor current is greater than 20 amps, the Control Unit must be connected to a relay/contactor.
