SPRING RETURN DIRECT-COUPLED DAMPER ACTUATORS 10/20 Nm (88/177 lb-in) FOR 2-POSITION CONTROL
GENERAL
These direct-coupled damper actuators provide two-position control for:
•air dampers,
•VAV units,
•air handlers,
•ventilation flaps,
•louvers, and
•reliable control for air damper applications with up to 1.5 m2 / 16 sq.ft (10 Nm / 88 lb-in) or 4.6 m2 / 50 sq.ft. (20 Nm / 177 lb-in) (seal-less dampers; air frictiondependent).
FEATURES
•Self-centering shaft adapter
•Removable access cover
•Mechanical end limits (non-adjustable)
•Rotation direction selectable by choice of mounting orientation
•Mountable in any orientation (IP54 only when mounted on a horizontal shaft with access cover below the shaft)
•Mechanical position indicator

Rotary Movement
The actuators are designed to open a damper by driving the damper shaft in either a clockwise or counterclockwise direction.
NOTE: Actuators are shipped in the fully-closed (spring return) position.
Two-Position Control
The two-position actuators are capable of being operated by a two-position (open/close) controller. Refer to wiring diagrams for correct connection.
