Hog Slat Inc. Newton Grove, NC USA APRIL 2024 REV IR 5 Ventilation 2. Wiring: Power drive unit has an attached power cord containing (4) wires identified as follows: L Direction HI L1 Direction HII Common Green/yellow stripe ground Determine the direction of rotation needed to achieve OPEN and CLOSE directions for the application. Apply rated voltage for the particular model to either L or L1 wires and Common to operate machine. 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 drive along with the hex bit found in the rubber gasket underneath the limit switch cover. At the end of the motor (fan end) there is a mating female hex socket. First reset limits using the instructions below. 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. Once the first direction is set, change directions of the drill and move load to the opposite position. Locate the control buttons on the LSC40 electronic limit switch. Apply power to drive and test in both directions and confirm unit stops at the desired positions HI HII S H I H II RESET LIMITS Press “HI” and “HII” at the same time. While pressing them, press “S” button and hold until LED indicators for position HI and HII turn red. SET LIMITS EITHER HI or HII DIRECTIONS Press the “S” button and hold then press HI or HII depending on the direction of rotation. Hold until the LED light for that direction turns green.

Hog Slat Inc. Newton Grove, NC USA APRIL 2024 REV IR 6 Ventilation The LSC40 has built in 0-10VDC and 4-20mA output to represent the position of the drive unit between limits. A 24VDC power supply is required per connection diagram below. If the 0-10V or 4-20mA output signals need to be inverted, locate dip switch “INV” and switch to opposite the existing setting. An optional HS1129 Actuator Auto/Man isolator Assembly (purchased separately) may be used to provide local AUTO/MANUAL control that can be mounted remotely. The HS1129 connects in series with the control power provided by the ventilation controller and the HS1171 series power drive unit. The HS1171 units can then be run in manual to aid in setting up limits etc. HS1129 Actuator Auto/Man isolator Assembly
