The EDA-8000 Electric Damper Actuator provides
clockwise and counterclockwise incremental control of
dampers and mounts directly on the damper drive
shaft, eliminating the need for costly and complicated
linkage combinations.
The mechanically limited torque output of 100 in·lb
provides long actuator life, protection of the controlled
equipment, and minimal setup and calibration time.
The EDA-8000 Electric Damper Actuator operates on
24 VAC power.

pplication
The EDA-8000 is designed to regulate control air
dampers in HVAC systems. Typical applications
include:
●positioning of D-1300 Series Dampers
●return air, or exhaust dampers
●face and bypass control
●blade positioning for variable volume fans
Refer to damper manufacturer’s information to properly
size the damper and actuator. Return to normal
actuators are recommended for use with outdoor air
dampers.
Operation
The EDA-8000 Electric Damper Actuator provides a
stall torque output of 100 in·lb with incremental control
of dampers. It can also be used in a variety of other
applications at 80 in·lb continuous load.
The EDA-8000 is used on dampers having externally
accessible 10 to 12 mm (0.394 to 0.472 inch) square
or 7/16 to 1/2 inch (11 to 12.5 mm) round shafts.
It is compatible with Johnson Controls D-1300
Dampers as a direct mount actuator. The EDA-8000
housing has additional mounting slots to aid adaptation
to unusual applications. Several kits are available to
solve virtually any mounting situation.
The EDA-8000 non-spring return actuator will drive the
damper through a full stroke cycle of 90° in
60 seconds.
In typical incremental operation, a controller provides
24 VAC to the Clockwise (CW) or Counterclockwise
(CCW) terminal on the actuator depending on the
desired movement of the damper. This signal causes
the motor to rotate in the proper direction and moves
the damper blades open or closed. When no control
signal is present, the actuator holds its position.
The actuator is energized as long as the 24 VAC signal
is present. Therefore, it is more efficient to pulse the
signal to the actuator, which will prevent excessive
drive time of the motor. The use of a controller and/or
software that provides a time out to remove the signal
at the end of rotation is preferred to leaving the signal
applied to the actuator at all times.

Dimension
Note: The actuator requires a minimum damper shaft
length of four inches from the mounting
surface. When determining shaft length,
consideration has to be given to channel
depth, insulation, etc. Refer to the following
dimensional drawings.
Before starting the job, obtain the damper installation
information to use as a reference when mounting the
actuator.

If access to the damper shaft is limited, or internal
mounting is required, mount the actuator remotely by
installing a six inch long, 1/2 inch diameter rod into the
coupler and use linkage accessories shown in the
Damper Accessory Kits , Order No. 268.1-100 located
in the
Damper and Actuator Manual, FAN 268.1 .
Mounting
!
CAUTIONS:
●Follow NEC and local electrical codes.
●Disconnect power supplies.
●Observe the ranges and limitations found in
Specifications.
●Do not install the actuator in applications
where its failure could result in personal injury
and/or loss of property.
●Do not install if explosive vapors, corrosive
vapors, or escaping gases will be present.
●Add protective control devices, as needed, to
prevent undesirable system failure modes.
Note: Use of the actuator’s top and bottom center
mounting slots with the isolation grommets is
the preferred mounting arrangement when
using shafts 10 mm (0.472 inch) square or
7/16 inch (11 mm) round or larger. If the duct
or wall is less than 16 gauge (0.06 inch or
1.5 mm), use the Universal Mounting Bracket
(D-3153-105).
When using the blade pin extension and/or the
universal mounting bracket, follow installation
procedures packaged with the product.
Direction Of Rotation
1. Firmly grasp the drive pin extension with a pliers
and manually close the damper blades.
2. Note which direction closes the damper, Clockwise
(CW) or Counterclockwise (CCW).
Figure 4: Removing Cover
3. Insert a screwdriver under the edge of the plastic
cover to gently pry off the cover. See Figure 4.

5. Hold the release lever up and fully rotate the
actuator coupler in the same direction as Step 2.
Note: For example, if the damper closed by rotating
the extension pin CCW, rotate the actuator
coupler fully CCW until the mechanical end
stop is reached. See Figure 6.

Standard Mounting
The EDA-8000 is not position sensitive and can be
mounted in any convenient orientation on a duct or wall
that is 16 gauge (0.06 inch or 1.5 mm) or thicker as
long as the drive shaft is perpendicular to the mounting
surface of the actuator.
Top Center
Mounting Slot
Figure 7: Actuator Against Duct
1. Position the actuator onto the blade pin extension
so that the actuator sits against the duct as shown
in Figure 7.
Note: The bottom center mounting hole looks the
same as the top mounting hole illustrated in
Figure 7.
2. Use of the actuator’s center mounting slots with
the isolation grommets is the preferred mounting
arrangement. If the duct or wall is less than
16 gauge (0.06 inch or 1.5 mm), use the
Universal Mounting Bracket (D-3153-105).
Note: Because of eccentric motion of the actuator
that occurs when using shafts smaller than
10 mm (0.394 inch) square or 1/2 inch
(12.5 mm) round, use the isolation grommet
only in the bottom center mounting slot.
3. Mark the location of the actuator’s top and bottom
mounting slots on the duct or wall.
4. Remove the actuator and coupler and set aside.
5. Drill two 5/32 inch (4 mm) holes in the duct or wall
at the marked locations.
Note: When using the universal mounting bracket,
drill two 11/64 inch holes.
6. Slide the actuator and coupler onto the pin
extension.
7. Secure the actuator to the wall or duct with the
screws and isolation grommets included in the kit.
8. Tighten the two square-head screws on the
actuator coupler.
9. Lift the manual release lever and hand turn the
coupler CW and CCW to check that the damper
blades fully open and close.
Note: The cover should remain off until the wiring is
completed.
