Sizing

Required Torque

In lieu of data from a Specification Engineer or Manufacturer, required torque for a given damper load can be determined using the following method:

Where: —T

= Required torque for the damper load.

—T

= Damper torque rating from the manufacturer,

expressed in either (lb-in.)/(sq ft) or (N•m)/(sq m). the damper load.

—A

= Damper area expressed in either sq ft or sq m.

Actuators Required

In lieu of data from a Specification Engineer or Manufacturer, the number of required actuators for a given damper load can be determined using the following method:

Where: — N = Number of actuators.

= Required torque for the damper load. (See above.)

—T

= Actuator torque rating.

— SF = Safety factor. NOTE: The safety factor accounts for variables such as mis-

alignments, aging of the damper, etc. 0.8 is a typical safety factor.

INSTALLATION

When Installing this Product...

1. Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous condition.

2. Check the ratings given in the instructions and on the product to make sure the product is suitable for your application.

3. Installer must be a trained, experienced service technician.

4. After installation is complete, check out product operation as provided in these instructions.

NOTES:

— When mounted correctly, these slots allow the

actuator to float without rotating relative to the damper shaft.

— Using other brackets or linkages, the actuator can

be foot-mounted or tandem-mounted.

Motor Damage Hazard. Deteriorating vapors and acid fumes can damage metal parts.

Install motor in areas free of acid fumes and other deteriorating vapors.

Equipment Damage Hazard. Tightly securing actuator to damper housing can damage actuator.

Mount actuator to allow it to float along its vertical axis.

Preparation

Before mounting the actuator onto the damper shaft, determine the: — Damper/valve opening direction for correct spring return

rotation. The actuator can be mounted to provide clockwise or counterclockwise spring return.

— Damper shaft size (see the Specifications section).

Determine Appropriate Mounting Orientation

The actuators are designed to open a damper by driving the damper shaft in either a clockwise or counterclockwise

direction (see Fig. 2).

NOTES:

— Actuators are shipped in the fully closed (spring

return) position.

— An arrow molded into the hub points to tick marks

on the label to indicate the hub rotary position.

Location

These actuators are designed to mount directly to a damper external drive shaft. The shaft coupling fastens to the drive shaft. The actuator housing includes slots which, along with an anti-rotation bracket, secure the actuator to the damper frame or duct work (see Fig. 8).

63-2607—6 4

Electrical Shock or Equipment Damage Hazard. Low voltage can shock individuals or short equipment circuitry.

Disconnect power supply before installation.

All wiring must agree with applicable codes, ordinances and regulations.

Fig. 2. Spring Return DCA mounting orientation.

Measure Damper/Valve Shaft Length

If the shaft is less than three inches in length, the shaft coupling must be located between the damper/valve and actuator housing. If the shaft length is more than three inches, the shaft coupling may be located on either side of the actuator housing.

S05, S10, S20 SERIES SPRING RETURN DIRECT COUPLED ACTUATORS

If the coupling must be moved from one side of the actuator to the reverse, follow these instructions (see Fig. 3):

1. Remove the retainer clip from the shaft coupling and set it aside for later use.

2. Remove shaft coupling from one side of the actuator.

3. Replace the shaft coupling on the opposite side of the

actuator aligning it based on the stroke labelling.

4. Replace the retainer clip on the shaft coupling using the groove of the coupling.

Select Actuator Control Signal

These actuators are available in two control types: — Standard: includes mode selection dial to select the desired

input signal.

— Enhanced: includes different mode selection dial to select

the desired input signal. Also includes dials for adjusting the input signal zero and span.

NOTE: Selections are made using a dial that appears on both

the front and back of the actuator (see Fig. 4). For available options, see Table 5.

To select the control signal simply turn the mode selection dial to the desired control signal (as indicated on the device label).

When operating in Modulating mode, the feedback signal matches the control signal.

Non-Standard Stroke

Mechanical Stroke Limit Reduction

For applications requiring a span less than 95 degrees, a simple adjustment can be made. When the rotational mounting of the shaft coupling is changed, the actuator drives less than the full 95 degrees stroke.

The stroke is adjustable in 5 degree increments. Once adjusted, the actuator drives until the shaft coupling reaches

motor to discontinue driving and the shaft coupling drives no farther. When the actuator returns, it stops at the fail-safe position.

To set the fail-safe position, proceed as follows:

1. Remove the retainer clip from the shaft coupling and set it aside for later use.

2. Remove shaft coupling from the actuator.

3. Rotate the coupling to the desired fail-safe position,

aligning it based on the stroke labelling. See Fig. 5.
