ML6131
Direct Coupled Actuator
PRODUCT DATA
FEATURES
• Mounts directly on damper shaft.
• 6 lb-in. torque.
• Selectable 45°, 60°, and 90° stroke in either clockwise
(cw) or counterclockwise (ccw) directions.
• 15 second timing model suitable for use with pressure
independent VAV systems.
• Magnetic coupling typically provides a maximum of
18 lb-in. stall torque eliminating the need for
mechanical stops or limit switch adjustments.
• Two field-addable auxiliary switches.
• Field-addable auxil

ML6131 DIRECT COUPLED ACTUATOR Preparation Before mounting the actuator onto the shaft, determine the following: 1. Size of the shaft (3/8 in. to 1/2 in.). 2. Direction the shaft rotates to open the device (cw or ccw). See Fig. 3. 3. Degrees of actuator stroke for opening device (45°, 60°, or 90°). If the shaft is 3/8 in. round or square, use part number 201391 Shaft Adapter provided inside the bag assembly shipped with the actuator. Place the adapter opposite the setscrews (see Fig. 4). M

ML6131 DIRECT COUPLED ACTUATOR OPERATION CHECKOUT To check out the ML6131, determine the direction the damper VAV Systems shaft moves to open the damper (cw or ccw). See Fig. 3: VAV systems control the temperature within a space by 1. Place 24 Vac across the appropriate COM and CW or varying the volume of supply air. Air is delivered to the space COM and CCW terminals to energize the actuator. The at a fixed temperature. The volume of supply air is controlled ML6131 should begin to open the d
