INSTALLATION
Some Spyder and Stryker controllers include a direct-coupled actuator with
declutch mechanism, which is shipped hard-wired to the controller. The
actuator mounts directly onto the VAV box damper shaft and has up to 44 lb-in.
(5 Nm) torque, 90-degree stroke, and 90 second timing at 60 Hz. The actuator
is suitable for mounting onto a 3/8 to 1/2 in. (10 to 13 mm) square or round
VAV box damper shaft. The minimum VAV box damper shaft length is 1-9/16 in.
(40 mm).
The two mechanical end-limit set screws control the amount of rotation from
12° to 95°. These set screws must be securely fastened in place. To ensure
tight closing of the damper, the shaft adapter has a total rotation stroke of
95° (see Fig. 1).
NOTES:
The actuator is shipped with the mechanical end-limit set screws set to 95 degrees of rota-tion. Adjust the two set screws closer together to reduce the rotation travel. Each “hash mark” indicator on the bracket represents approxi- mately 6.5° of rotation per side. The declutch button, when pressed, allows you to rotate the universal shaft adapter (see Fig. 1).
IMPORTANT
Determine the damper rotation and opening angle prior to installation. See
Fig. 2.
Removing the Old Actuator
- Loosen the two u-bolt shaft adapter nuts to release the actuator from the damper shaft.
- Remove any screws that attach the controller to the equipment and remove the assembly from the damper shaft.
- Use the tip of a flat head screwdriver to release the two tabs on the bottom of the actuator enclosure by gently prying upward.
- With the bottom tabs released push the cover upward to release the tabs on the top side of the cover. With all the tabs released, remove the cover from the assembly and set aside for later reuse.
- Remove the 3-pin connector that links the actuator to the controller, by pulling away from the actuator circuit board.
- Gripping the output end of the actuator, pull out to release from the top locking mechanism. When released, lift the actuator straight up to disengage the anti-rotation from the bottom of the enclosure.

Installing the New Actuator
-
Install new actuator by inserting the anti-rotation end below the foam block in the bottom of the hous-ing, then push the output end of the actuator into the locking mechanism. It should distinctly snap into place.
NOTE: The actuator must be flat against the bot- tom of the enclosure. If not, check that the slot of the actuator is below the plastic anti-rotation feature in the bottom of the enclo-sure. -
Replace the wiring connector, with the cables point-ing down and away from the circuit board.
-
Replace the cover that was previously set aside by latching the tabs on the top of the housing, and pushing down on the bottom of the cover until the bottom tabs engage.
NOTE: The actuator declutch button may need to be pushed down while rotating the cover down to engage the bottom tabs. -
Follow the steps in “Mounting Actuator Onto Damper Shaft” below to re-install the actuator onto the VAV box.
Mounting Actuator Onto Damper Shaft
Tools required:
— Phillips #2 screwdriver – end-limit set screw adjustment
— 8 mm wrench – shaft adapter nuts
The unit is shipped with the actuator set to rotate open in the clockwise (CW)
direction to a full 95 degrees. The extra 5 degrees ensures a full opening
range for a 90 degree damper. The installation procedure varies depending on
the damper opening direction and angle:
- If the damper rotates clockwise (CW) to open, and the angle of the damper open-to-closed is 90 degrees:
- Manually open the damper fully (rotate clock-wise).
- Using the declutch button, rotate the universal shaft adapter fully clockwise.
- Mount the actuator to the VAV damper box and shaft.
- Tighten the two bolts on the centering clamp (8 mm wrench; 70.8–88.5 lb-in. [8–10 Nm] torque). When the actuator closes, the damper rotates CCW 90 degrees to fully close.
- If the damper rotates clockwise (CW) to open, and the angle of the damper open-to-closed is 45 or 60 degrees:
- Manually open the damper fully (rotate clock-wise).
- he actuator is shipped with the mechanical end-limits set at 95 degrees. Adjust the two mechanical end-limit set screws to provide the desired amount of rotation. Adjust the two set screws closer together to reduce the rotation travel.
- Tighten the two mechanical end-limit screws (Phillips #2 screwdriver; (26.5–31 lb-in. [3.0–3.5 Nm] torque).
- sing the declutch button, rotate the universal shaft adapter fully clockwise.
- Mount the actuator to the VAV damper box and shaft.
- Tighten the two bolts on the centering clamp (8 mm wrench; 70.8–88.5 lb-in. [8–10 Nm] torque).
- When the actuator closes, the damper rotates CCW either 45 or 60 degrees to fully close.
- If the damper rotates counterclockwise (CCW) to open, and the angle of the damper open-to-closed is 90 degrees:
- Manually open the damper fully (rotate counter-clockwise).
- Using the declutch button, rotate the universal shaft adapter fully counterclockwise.
- Mount the actuator to the damper box and shaft.
- Tighten the two bolts on the centering clamp (8 mm wrench; 70.8–88.5 lb-in. [8–10 Nm] torque). When the actuator closes, the damper rotates CW 90 degrees to fully close.
- If the damper rotates counterclockwise to open, and the angle of the damper open-to-closed is 45 or 60 degrees:
- Manually open the damper fully (rotate counter-clockwise).
- The actuator is shipped with the mechanical end-limits set at 95 degrees. Adjust the two mechanical end-limit set screws to provide the desired amount of rotation. Adjust the two set screws closer together to reduce the rotation travel.
- Tighten the two mechanical end-limit screws (Phillips #2 screwdriver; 26.5–31 lb-in. [3.0–3.5 Nm] torque).
- Using the declutch button, rotate the universal shaft adapter fully counter-clockwise.
- Mount the actuator to the VAV damper box and shaft.
- Tighten the two bolts on the centering clamp (8 mm wrench; 70.8–88.5 lb-in. [8–10 Nm] torque).
- When the actuator closes, the damper rotates CW either 45 or 60 degrees to fully close.
IMPORTANT
Special precautions must be taken for dampers that open in a CCW direction.
The actuator is shipped with its rotation direction set to CW to Open, which
applies to the damper direction in steps 1 and 2 above. If the damper shaft
rotates in the CCW direction to open, the controller software must be
programmed to change the rotation to
“Reverse to Open,” which applies to the damper direction in steps 3 and 4
above.
Panel Mounting
The controller enclosure is constructed of a plastic base plate and a plastic
factory-snap-on cover.
NOTE: The controller is designed so that the cover does not need to be removed
from the base plate for either mounting or wiring.
The controller mounts using four screws inserted through the corners of the
base plate. Fasten securely with four No. 6 or No. 8 machine or sheet metal
screws.
The controller can be mounted in any orientation. Ventilation openings are
designed into the cover to allow proper heat dissipation, regardless of the
mounting orientation.
