1 63-2483—2G.R. • Rev. 4-95 • ©Honeywell Inc. 1995ML6185Spring ReturnDirect Coupled ActuatorThe ML6185 Spring Return Direct CoupledRotary Actuator is a floating control motor that canbe used with controls that provide switched orfloating single pole double throw (spdt) controloutput to operate dampers in heating, ventilation,and air conditioning (HVAC) applications.n Mounts directly on horizontal 3/8 in., 1/2 in., and5/8 in. round and square damper shafts by using theappropriate insert. Most models are shipped with 1/2 in. insert.n Provides 50 lb-in. running and spring return torque.n Magnetic coupling eliminates the need for mechani-cal stops or limit switch adjustments by limitingstall torque to 130 lb-in. maximum.n 95° stroke provides necessary compression of rub-ber/neoprene gaskets commonly used on 90° lowleakage dampers.n 88 second synchronous timing can eliminate needfor feedback position indication in closed-loop tem-perature control applications.n Removable splined output hub permits premountingof the hub on the damper shaft, providing installationflexibility.n Reversible mounting allows actuator to be used foreither clockwise (cw) or counterclockwise (ccw)spring rotation.n Designed for both single-point and three-point mount-ing, providing installation flexibility.n Available with or without a time-out feature. Modelswithout the time-out feature are designed to be usedwith intelligent building management system and/orcontroller.n Standard models have two 8 mm x 12 mm long setscrews for securing the damper shaft. Actuatormodels are available for various shaft sizes that willallow the damper shaft to operate centered inside theoutput hub.n Standard one-meter cable with color-coded lead-wires allows external wire connections with 1/2 in.conduit connectors.n Can mount two or more actuators on one dampershaft to increase output torque for use on damperslarger than 16 square feet.63-2483-2CONTENTSSpecifications ................................................. 2Ordering Information ..................................... 2Installation ..................................................... 4Operation ....................................................... 9Checkout ....................................................... 11
