Hog Slat Inc. Newton Grove, NC USA AUG 2026 REV A3 6 Ventilation 3. Setting travel limits: With limit switch cover removed from step 1. The Power Drive unit limit switch can be set up without power to the drive. Use a drill driver along with the hex bit found in the rubber gasket underneath the limit switch cover (or found in plastic bag on the revised model with blue cover) At the end of the motor (fan end) there is a mating female hex socket. First reset limits using the instructions below. (Turn off power to drive, limits cannot be reset or set if the drive is powered) Then use the drill to rotate the motor until the load is in the desired position. Note the direction of rotation required to bring load to that position. Use below instructions to program limit for that position. Once the first direction is set, change directions of the drill and move load to the opposite position. Use limit switch instructions to program limit for the second direction position. Apply power to drive and test in both directions and confirm unit stops at the desired positions Once limit switch is set, replace the hex key in the rubber gasket (or snap inside blue plastic lid) for safe keeping.
