Brand: Johnson Controls

Model: EDA-8000

Type: Product/Technical Bulletin

Johnson Controls EDA-8000 Electric Damper Actuator provides precise and reliable control of dampers in HVAC systems. The device operates on 24VAC power and provides incremental clockwise or counterclockwise rotation, making it suitable for a wide range of applications.

The EDA-8000 is designed to be mounted directly onto the damper shaft, eliminating the need for complex linkage combinations. Its mechanically limited torque output of 100 in·lb ensures long actuator life and protection of the controlled equipment.

The actuator features over-torque protection, preventing the need for setup or maintenance of limit switches and extending its lifespan. With 90-degree clockwise or counterclockwise rotation and compatibility with dampers having externally accessible shafts, the EDA-8000 offers versatility in positioning and integration.

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.

peration

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.

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

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).

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

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.
