Wiring a Single ARD (Power Closed) to a
Control Panel
Fig. 4. ARD configured as power closed.
Changing ARD Power Closed to Power Open
1. Remove power to motor (damper blade in open posi-
tion).
2. Loosen socket head cap set screw and remove motor.
3. Pinch and push grommet (with hole) to remove.
4. Push out plastic plug.
5. Exchange the positions of the grommet and the plug.
6. Manually place damper blade in closed position.
7. Place motor on opposite side of damper. (This side
should now have the grommet with the hole.)
8. Tighten the cap screw. (Make sure the blade is in the
closed position.)
9. If using a zoning panel, change the power wires from
M1 and M6 to M1 and M4.
Changing ARD Power Open to Power Closed
(Factory Default)
1. Disconnect the motor wiring (damper blade in closed
position).
2. Loosen socket head cap set screw and remove motor.
3. Pinch and push grommet (with hole) to remove.
4. Exchange the positions of the grommet and the plug.
5. Manually place damper blade to open position.
6. Place motor on opposite side of damper. (This side
should now have the grommet with the hole.)
7. Tighten the cap screw. (Make sure the blade is in the
open position.)
8. If using a zoning panel, change the power wires from
M1 and M4 to M1 and M6.
CHECKOUT
CAUTION
Possible Equipment Damage
Do not manually open or close the damper as this can
damage the actuator.
To check out the ARD:
1. With 24 Vac applied to the motor leads, observe the
motor powering the damper to the closed position.
2. When energized, verify that the actuator connection
coupling rotates in a clockwise direction (as viewed from
the operator base end) and that the damper shaft turns
with the coupling.
3. With power removed, observe the damper returning to
the normally-open position.
NOTE: To remove power, disconnect one wire from the
motor.
4. If the motor does not operate smoothly and without hes-
itation throughout the complete opening and closing
stroke, examine the damper and the shaft for free rota-
tion within the duct.
5. If the full opening and closing is not achieved, check
that the lower adjustment lever is to the extreme left and
the upper lever is to the extreme right. See Fig. 2.
