MS41-6153 Series

Apply a 0 to 10 Vdc control signal between wire 8 (Y) and wire 2 (G0) to operate the damper actuator. The angle of rotation is proportional to the control signal. A 0 to 10 Vdc position feedback output signal is available between wire 9 (U) and wire 2 (G0) to monitor the position of the damper motor.

In the event of a power failure, the actuator holds its position. In the event that only the control signal is lost, the actuator returns to the “0” position.

MF41-6153

A floating control signal controls the damper actuator. The actuator’s angle of rotation is proportional to the length of time the signal is applied. A 24 Vac control signal to wire 6 (Y1) causes the actuator coupling to rotate clockwise. A 24 Vac control signal to wire 7 (Y2) causes the actuator coupling to rotate counterclockwise.

To reverse the direction of rotation, wires 6 (Y1) and 7 (Y2) can be interchanged.

With no control voltage, the damper actuator holds its position.

In the event of a blockage in the damper, the actuator is overload protected over the full range to prevent damage to the actuator.

An improperly tuned loop will cause excessive repositioning that will shorten the life of the actuator.

The type of actuator required depends on several factors:

1. Obtain damper torque ratings (ft-lb/ft 2 or Nm/m 2 ) from the damper manufacturer.

2. Determine the area of the damper.

3. Calculate the total torque required to move the damper:

Total Torque =

Torque Rating x Damper Area

SF

1

1 Safety Factor: When calculating the total torque required, a safety factor should be included for unaccountable variables such as slight misalignments, aging of the damper, etc. A suggested safety factor is 0.80.

4. Select the non-spring return actuator type using Table 2.

Mounting and

Installation

Manual Override

Installation Instructions

• Place the actuator on the damper shaft so that the front of the actuator is accessible.

(The label and the manual override button are on the front side.)

• The minimum damper drive shaft is 3/4-inches (20mm). The shaft length determines whether the shaft adapter will be mounted on the front or back of the actuator.

• See Specifications for minimum and maximum damper shaft dimensions.

• Set auxiliary switches, DIP switches, and Offset/Span as required by your application.

(See following sections for details.)

• The position indicator can be mounted to show either the clockwise or counterclockwise 0 to 90 scale.

• An anti-rotation bracket is included with the actuator.

• The shaft adapter and mounting parts are shipped in a separate container with the actuator.

• The actuator is shipped from the factory with a 5° pre-load to ensure tight damper close off.

• For detailed mounting instructions, see Installation Instructions F-27212.

To move the damper blades and lock the position with no power present:

1. Hold down the PUSH button.

2. Make adjustments to the damper position.

3. Release the PUSH button.

Once power is restored, the actuator returns to automated control.

Mechanical

Range Adjustment

Figure 2. Manual Override.

The angular rotation is adjustable between 0° and 90° at 5-degree intervals. The range of shaft movement is limited by mounting the shaft adapter:

1. Loosen the shaft adapter from the damper shaft and remove the actuator from the damper shaft.

2. Remove the clip and shaft adapter from the actuator.

Mechanical Range

Adjustment (cont.)

3. Return the actuator gear train to the “0” position using the steps that follow for the clockwise or counterclockwise damper shaft rotation.

Clockwise to open: a. Insert the shaft adapter to the right as close as possible to the raised stop. See

Figure 4.

b. Hold down the PUSH button and rotate the shaft adapter to the left until it stops.

See Figure 5.

c. Release the PUSH button.

d. If the shaft adapter is not resting against the left raised stop, remove the adapter and insert it against the left stop. e. Place the position indicator to the “0” position on the outside scale.

See Figure 6.

Counterclockwise to open: a. Insert the shaft adapter to the left as close as possible to the raised stop.

b. Hold down the PUSH button and rotate the shaft adapter to the right until it stops. c. Release the PUSH button.

d. If the shaft adapter is not resting against the right raised stop, remove the adapter and insert it against the right stop. e. Place the position indicator to “0” on the inside scale.

4. Determine the angle of rotation for the damper blade shaft. Subtract that amount from

90°.

5. Remove the shaft adapter and insert it with the position indicator pointing to the mark on the scale calculated in the previous step. See Figure 6.

6. Attach the clip.

7. Rotate the damper blade shaft to its “0” position.

8. Return the actuator to the damper shaft and tighten the shaft adapter to the damper shaft.

Installation Instructions

To change the settings of A and B:

NOTES:

• The scale is only valid when the actuator is in the “0” position on clockwise motion.

• For the counterclockwise rotation, the shaft adapter/ position indicator has to move from 90° to 0° and then adjust the auxiliary switches. After the auxiliary switches are adjusted, the shaft adapter/position indicator has to move back to the 90° position.

• Use the adjustment tool provided with the actuator to turn the switch adjustment dials to the desired signal setting.

Factory setting:

Switch A: 5°

Switch B: 85°

Recommended range:

Switch A: 0° to 45°

Switch B: 45° to 90°

NOTE: Use the long arm of the “†” to point to the position of switch A. Use the narrower tab on the red ring to point to the position of switch B.

• Factory setting:

Self-adapting

Caution: When turning the self-adaptive feature on, or after a software reset with the feature on, the actuator will enter a five-minute calibration cycle as the actuator adjusts to the rotation limits of the system.

A software reset happens after power on, or may be caused by electrostatic discharge (ESD) at levels of

2kV and above.

Wiring

All wiring must conform to NEC and local codes and regulations.

Use earth ground isolating step-down Class 2 transformers. Do not use autotransformers.

The maximum rating for a Class 2 step-down transformer is 100 VA. Determine the supply transformer rating by summing the VA ratings of all actuators and all other components used. It is recommended that one transformer power no more than 10 actuators (or 80% of its VA).

Warnings:

Installations requiring Conformance:

• Except for the auxiliary switches (See Warning above) all wiring for actuators must be safety extra-low voltage (SELV) or protective extra-low voltage (PELV) per HD384.

• Use safety transformers per EN61558 with double isolation, designed for 100% dutycycle for supplying SELV or PELV circuits.

• Over-current protection for supply lines is maximum 10A.

Caution:

Do not parallel MF41-6153 actuators with any other type of actuator.

Warning:

Do not open the actuator.

If the actuator is inoperative, replace the unit.

• Check that the wires are connected correctly.

• Check that auxiliary switches, DIP switches, and Offset/Span are set correctly.

• Set the DMM dial to Vac and verify that the operating voltage is within range.

• If the actuator is not working, check the damper for blockage. If blocked, remove the obstacle and cycle the actuator power off and on. The actuator should resume normal operating mode.
