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
