Installing 3/8" Reduced (thin) Wall Flexible Conduit onto One or Both Sides
of Actuator
Flexible conduit may be installed onto one or both sides of the actuator (refer to Figure-8
and Figure-9 ). Install each conduit as follows:
1. Determine the side of the actuator to which the flexible conduit is to be att
2. Remove the knockout, using channel lock pliers, on the selected side of the actuator.
Refer to Figure-7 .
3. Make the required connections. Refer to Figure-1 , Figure-2 , and Figure-3 to
determine your particular application. Refer to Table-5 to determine the damper position
versus the input signal.

4. Slip the conduit onto the base, over the ribs. Refer to Figure-8 and
5. Rotate the damper to its open position. Install and secure the damper crank arm (with
ball joint connector) to the damper shaft, positioning the crank arm as follows (refer
to Figure-16 ):
a. To achieve 60° of damper rotation, position the crank arm so that it is pointed
towards the actuator at 30° from its mid-stroke position.
b. To achieve 90° of damper rotati
towards the actuator at 45° from its mid-stroke position.
6. Install the damper rod by sliding one end through the ball joint connector mounted on
the damper crank arm, and the other end through the straight connector on the actuator
crank arm. Tighten the nut on the actuator crank arm’s straight connector. Cut off any
excess length of damper rod.
7. For normally open dampers, tighten the nut on the ball joint
crank arm. To ensure that the damper closes completely, make adjustments so that the
actuator is 1/16" (1.6 mm) from the extended end of stroke when the damper
Verify and, if necessary, make final adjustments during system checkout.
8. For normally closed dampers, rotate the damper crank arm until the damper is closed.
While holding the damper closed, tighten the nut on the ball joint connector on the
damper crank arm. To ensure that the damper closes completely, make adjustments so
that the actuator is 1/16" (1.6 mm) from the retracted end of stroke when the damper

Final adjustment of the actuator and damper must be performed when the system is

Valve
For valve assembly details refer to AV-600 Hydraulic Actuator Valve Linkage Kit, F-26279

After the entire system has been installed and the actuator has been powered up, perform
the following checks for proper system operation.
Caution: Never power the actuator without a spring return linkage attached.
If the sensed media is within the controller’s setpoint range, the actuator can be positioned
by adjusting the controller setpoint up and down. Check for correct operation of the actuator
(valve or damper) while the actuator is being stroked.
1. Apply power to the actuator.
2. Disconnect the actuator’s control leads from the controller.
3. Make the actuator shaft extend fully by shorting the red lead to the blue lead.
4. Make the actuator shaft retract fully by shorting the red lead to
5. Check for proper operation of the valve or damper as the actuator is operated
6. Reconnect the actuator wires to the controller.
7. Remove power from the actuator.
1. Apply power to the actuator.
2. Disconnect the actuator’s control leads from the controller.
3. Attach the slidewire leads from the calibration box (TOOL-209) to
on the actuator.
4. Manually position the actuator by turning the knob of the calibration box (TOOL-209).
Turning the knob in the clockwise direction retracts the actuator shaft. Turning the knob
in the counterclockwise direction extends the actuator shaft.
5. Check for proper operation of the valve or damper as the actuator is operated.
