OPERATION / FUNCTIONS
Contents of Package
1 Self-centering shaft adapter
2 Retainer clip
3 Rotational angle scales (0...90° / 90...0°)
4 Mechanical end limits (non-adjustable)
5 Hex wrench for manual adjustment
6 Access cover
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.
Position Indication
An arrow molded into the hub points to tick marks on the label
to indicate the hub rotary position.
