Hog Slat Inc. Newton Grove, NC USA December 2022 37 GROW-DISK™ Feed System Drive Unit Chain Safety Switch and Door Switch Each Drive unit is equipped with 2 safety switches. The door switch prevents the system from starting with cover off or shuts it down if the cover would be removed during operation. The chain safety switch will shut off the system if the conveyer chain tension is too loose or conveyer chain is blocked. Drive Unit Chain Safety Switch The safety switch is located inside the Drive Unit as shown below. The switch can be activated in either direction by a bracket which is attached to the idler wheel. If either side of the bracket (caused by chain being too long or too short) comes in contact with the limit switch, it will shut the system down.

Once the problem has been corrected, pull the blue reset button on the safety switch and reset the HSCD200 Controller.
