7. Assemble the ball joint in the crankarm:
a. Remove the hex nut from the ball joint.
b. Insert the ball joint through the slot in the
crankarm.
c. Add the serrated lock washer and tighten the
ball joint hex nut using the recommended
torque of 2.3 to 2.8 N·m (20 to 25 lb·in.).
8. Proceed with the installation of the remaining
hardware required to connect the actuator
crankarm to the drive blade, jackshaft, or crankarm
to be driven.
Setup and Adjustments
Adjusting the Linkage
Make the necessary adjustments to fit the actuator’s
stroke limit to the application:
• Adjust the field-supplied linkage components to
use the actuator’s internal end-stops for stroke
control whenever practical.
• Apply the external adjustable end-stop if linkage
adjustment is not practical. An end-stop is supplied
with the actuator or can be ordered separately
(M9208-603 Adjustable Stop Kit). Refer to the
Limiting Rotation Range Using M9208-603
Adjustable Stop Kit section of the actuator
installation instructions, listed in Table 1, for limiting
the stroke of the actuator. When using the
M9208-100 Remote Mounting Kit, the washer is
used to limit the stroke in place of the gripper.
Checkout
Use the following steps to ensure that the actuator
assembly components function properly, and that the
actuator operates freely from one rotation limit to the
other.
1. Connect all control wires to the actuator.
Note: Refer to the Wiring section of the actuator
installation instructions listed in Table 1.
2. Apply power to the actuator.
3. Cycle the actuator fully in both CW and CCW
directions. Ensure that the mechanism’s stroke is
limited by the actuator internal or external
end-stops.
4. Ensure that the crankarm properly exercises the
full range of the drive blade, jackshaft, or crankarm
as required by the application without over-driving
the linkage hardware.
If the actuator is not operating properly, refer to the
appropriate actuator installation instructions indicated
in Table 1.
!
CAUTION: Risk of Property Damage.
Before applying power to an electric
actuator that is installed in a damper
application using a remote-mount linkage
kit, confirm that the actuator end-stops
are used to control the stroke applied to
the damper linkage. Failure to use
actuator end-stops to control the stroke
can lead to premature equipment failure
and/or property damage.
IMPORTANT: Adjustable stop is for use with
limiting the driving stroke only. Using the stop in the
spring return direction could damage the actuator or
linkage parts.
