5. Hold the DXR Actuator Package steady and
tighten the set screw (Figure 5) to the following
inch pounds of torque:
–
60 inch pounds – solid steel or plastic graphite
composite (
hollow steel shafts require an insert
to prevent shaft damage!)
–
38 inch pounds – hollow aluminum shafts
Save the hex wrench. Adjust if necessary using
manual override. DO NOT remove the actuator
from the base-plate.
CAUTION! It is EXTREMELY IMPORTANT to
fully tighten the set screw. Loose set screws are
the leading cause of actuator control failure.

6. After viewing Figure 6, secure the base plate
with only two self-tapping screws (using more
may obstruct the damper’s range of motion).
