Installation

Overview

EDA-8102 Electric Damper Actuator

1. Follow NEC and local electrical codes.

2. Disconnect all power supplies.

3. Observe ranges and limitations for individual model.

4. Do not install the actuator in applications where its failure could result

in personal injury and/or loss of property.

5. Do not install if explosive vapors, corrosive vapors, or escaping gases

will be present.

6. Add protective control devices as needed to prevent undesirable

system failure modes.

Note: Before starting the job, obtain the damper installation information

to use as a reference when mounting the actuator.

1. Locate the preferred driving blade on the damper.

2. Cut a 1-1/4 inch (32 mm) hole in the duct or wall over the driving

blade pin.

3. Attach the drive pin extension to the drive pin and secure using the

clip provided.

4. Firmly grasp the drive pin extension with a pliers and manually close

the damper blades.

Note: The actuator can be mounted in any orientation.

1. Position the actuator onto the drive pin extension so that the actuator

sits against the duct.

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), order and 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 of the isolation grommets in the center

mounting slot is required.

3. Mark the location of the actuator's top and bottom mounting slots on

the duct or wall.

4. Remove the actuator and set aside.

5. Drill 5/32 inch (4 mm) holes in the duct or wall at the marked

locations.

6. Slide the actuator onto the drive pin extension.

7. Secure the actuator to the wall or duct with the screws and insulators

included in the kit.

8. Tighten the two square-head screws on the actuator coupler.

Note: The cover should remain off until the wiring is completed.

CAUTION: Disconnect all power before wiring the actuator to

avoid electrical shock or damaging the equipment.

Note: The EDA-8102 is factory set for 90° of rotation and a voltage

control signal of 1 to 9 VDC. To change these settings, see the

section Changing Rotation To Less Than 90° or the appropriate

signal calibration.

1. Apply power to the unit.

2. Refer to the controller's manual for directions on checking out a newly

installed device.

3. Use the controller to drive the actuator fully clockwise and

counterclockwise.

4. Verify that the damper blades fully open and close.

5. Install the plastic cover.

Procedure

EDA-8102 Electric Damper Actuator 7

The EDA-8102 is factory set for 90° of rotation and a control signal of 1

to 9 VDC. If the amount of rotation or the control signal must be changed

from factory settings, use the following procedures. Refer to Figure 7 for

the location of the potentiometer and terminal blocks in the procedures.

Figure 9: Rotation Setting

1. Verify jumper W2 is set to the voltage (V) position.

2. Verify jumper W1 is set in the desired position:

DCW for clockwise driven rotation.

DCCW for counterclockwise driven rotation.

Note: Spring return direction is NOT reversible.

3. Turn the offset potentiometer (R39) to its mid-position.

4. Turn the span potentiometer (R35) fully counterclockwise.

5. Turn the CCW potentiometer (R36) fully clockwise.

6. Connect a jumper from terminal IN (TB1) to terminal +15 (TB2) as

shown in Figure 9. The actuator rotates until the end stop is reached.

7. Slowly adjust the stroke potentiometer (R37) until the actuator rotates

to the desired end stop position.

8. Remove the jumper between terminal IN and +15.

Note: Calibration of offset and span is required after changing rotation.

Depending on controller application, proceed with the appropriate

calibration procedure.
