Hog Slat Inc. Newton Grove, NC USA August 2019 REV A3 2 Grow-Flex™ Feed Systems Operation: To control fill auger system: Connect a HS809 to a HS809U Normally Closed proximity switch mounted in the side wall of the hopper at the desired upper feed height. When feed is above the proximity switch, the HS809 output will turn off immediately. This set-up would be connected to a fill auger control unit(s) such as HS693 or HS593 (see wiring diagrams). Once the feed drops below the proximity switch, a time delay will begin. This time delay allows the feed level to drop further down the hopper before restarting the fill auger. To control Feed line auger: Connect a HS809 to a HS809L Normally Open proximity switch mounted in the side wall of the hopper at the desired lower feed height. When feed is below the proximity switch, the HS809 output will turn off immediately. This set-up would be connected to feed line auger which pulls feed from the feed hopper such as an end of line control HS8500. Once the feed rises above the proximity switch, a time delay will begin. This time delay allows the feed level to continue to rise within the hopper to a desired level before turning on the feed line auger(s). The HS809 has two independent outputs which can be connected to control two fill augers or two feed line augers. Electrical Specifications: Relay Output Contact Rating: 1 ½ HP @ 220-240VAC 50/60 Hz per Output contact. Installation Instructions: 1. Select location to mount the HS809. Location should provide adequate ventilation with safe and easy access. 2. Secure enclosure using four mounting feet provided. 3.
