The “10 questions” method for sizing and selection is recommended as the best method for your actuation requirements. Use the ‘Application Data’ column in this chart as a worksheet

to help in the selection process. This data, along with the ‘Actuator Product Range’ charts on pages 2 and 3, allow for the best selection of a Trane actuator.

Direct coupling has become the industry standard. Some retrofit applications do not allow direct coupling.

Some applications require the additions of an auxiliary switch for proof of position. Or a retrofit application may require an additional mounting bracket and linkage kit. You must identify these needs prior to leaving the job site or ordering products.

Control Signal Overview

Trane actuators are compatible with many control inputs. There are many signals to select from with today’s controllers.

What does ‘on-off’, ‘open-close’, ‘3-point’, ‘tri state’, ‘floating point’, ‘proportional modulation’, mean?

Trane will help you understand more on this control signal jungle with a quick overview:

On-Off or Open-Close: The actuator is able to drive either to its full open position, or to its full closed position. The same indication is used for Spring return type actuators. However the actuator will drive to its full open position and spring return to its zero position. This can also be reversed.

3-Point, Tri-state, Floating Point: The actuator has both clockwise (CW) and counter-clockwise (CCW) control inputs. One drives the actuator to its open, the other to its close position. If there is no signal (Null point) on either input the actuator simply stays in its last position.

Proportional Control: The Actuator drives proportional to its control input and modulates through-out its angle of rotation. This control type is usually a variation of VDC. Common values are:

0-10 VDC 2-10 VDC

It is common to also have a 0-20 mA output from a controller. This can be very easily converted to 0-10VDC or 2-10 VDC with a 500Ω resistor.

TAF24 (-S)

On-off, Spring Return Fail-Safe, 24 V

Torque min. 133 in-lb, for control of air dampers Application

For on-off, fail-safe control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications. Control is on-off from an auxiliary contact, or a manual switch.

The actuator is mounted directly to a damper shaft up to 1.05” in diameter by means of its universal clamp. A crankarm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft.

Operation

The TAF series actuators provide true spring return operation for reliable fail-safe application and positive close off on air tight dampers. The spring return system provides consistent torque to the damper with, and without, power applied to the actuator.

The TAF series provide 95° of rotation and are provided with a graduated position indicator showing 0° to 95°. The TAF has a unique manual positioning mechanism which allows the setting of any damper position within its 95° of rotation. The TAF series actuators are shipped at +5° (5° from full fail-safe) to provide automatic compression against damper gaskets for tight shut-off. When power is applied to the TAF series, the manual mechanism is released. The actuators will now try to close against the 0° position during its normal control operations. The manual override can also be released physically by the use of a crank supplied with the actuator.

The TAF uses a brushless DC motor which is controlled by an Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the actuator’s rotation and provides a digital rotation sensing function to prevent damage to the actuator in a stall condition. The actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches.

The TAF24-S version is provided with 2 built in auxiliary switches. These SPDT switches are provided for safety interfacing or signaling, for example, for fan start-up. The switching function at the fail-safe position is fixed at +5°, the other switch function is adjustable between +25° to +85°.

For all accessories, see pages 110 and 132.

Torque min. 133 in-lb, for control of air dampers Application

For proportional modulation of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications.

The actuator is mounted directly to a damper shaft up to 1.05” in diameter by means of its universal clamp. A crankarm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft.

The actuator operates in response to a 2 to 10 VDC, with the addition of a 500Ω resistor, a 4 to 20 mA control input from an electronic controller or positioner. A 2 to 10 VDC feedback signal is provided for position indication or master-slave applications.

Operation

The TAF series actuators provide true spring return operation for reliable fail-safe application and positive close-off on air tight dampers. The spring return system provides constant torque to the damper with, and without, power applied to the actuator.

The TAF series provides 95° of rotation and is provided with a graduated position indicator showing 0 to 95°. The TAF has a unique manual positioning mechanism which allows the setting of any damper position within its 95° of rotation. The actuator is shipped at +5° position (5° from full fail-safe) to provide automatic compression against damper gaskets for tight shut-off. When power is applied, the manual mechanism is released and the actuator drives toward the full fail-safe position. The actuator will memorize the angle where it stops rotating and use this point for its zero position for its normal control operations. The manual override can also be released physically by the use of a crank supplied with the actuator.

The TAF uses a brushless DC motor which is controlled by an Application Specific Integrated Circuit (ASIC) and a microprocessor. The microprocessor provides the intelligence to the ASIC to provide a constant rotation rate and to know the actuator’s exact zero position. The ASIC monitors and controls the brushless DC motor’s rotation and provides a digital rotation sensing function to prevent damage to the actuator in a stall condition. The actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches.

Installation Instructions

Mechanical Installation

Standard Mounting

Mechanical Operation

The actuator is mounted directly to a damper shaft up to 1.05” in diameter by means of its universal clamp. A crankarm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft. The TAF series actuators provide true spring return operation for reliable fail-safe application and positive close-off on air tight dampers. The spring return system provides constant torque to the damper with, and without, power applied to the actuator. The TAF…-S versions are provided with 2 built-in auxiliary switches. These SPDT switches are provided for safety interfacing or signaling, for example, for fan start-up. The switching function at the fail-safe position is fixed at +5°, the other switch function is adjustable between +25° to +85°.

Automatic Airtight Dampers/Manual Override

The TAF series provides 95° of rotation and is provided with a graduated position indicator showing 0° to 95°. The TAF has a unique manual positioning mechanism which allows the setting of any damper position within its 95° of rotation. A pre-tensioned spring automatically tightens damper when power is applied to the actuator, compensating for damper seal deterioration. The actuator is shipped at +5° (5° from full fail-safe) to provide automatic compression against damper gaskets for tight shut-off. When power is applied, the manual mechanism is released and the actuator drives toward the full fail-safe position.

Note:The TAF…series actuator is shipped with the manual override adjusted for a +5° position at the universal clamp (not at full fail-safe, 0° ). This allows for automatic compression of damper blade seals when the actuator is in use, providing tight shut-off. This assumes that the damper is to have tight shut-off at the fail-safe position. If tight close-off is desired at the opposite direction from fail-safe, the manual override should be released so the actuator can go to the full fail-safe position. See the manual override instructions.

1. Manually move the damper to the fail-safe position (usually closed). If the shaft rotated counterclockwise ( ), this is a CCW installation. If the shaft rotated clockwise ( ), this is a CW installation. In a CCW installation, the actuator side marked “CCW” faces out, while in a CW installation, the side marked “CW” faces out. All other steps are identical.

2. The actuator is usually shipped with the universal clamp mounted to the “CCW” side of the actuator. To test for

Determining Torque Loading and Actuator Sizing

Damper torque loadings, used in selecting the correct size actuator, should be provided by the damper manufacturer. If this information is not available, the following general selection guidelines can be used.

Damper Type Torque Loading

Opposed blade, without edge seals, for non-tight close-off applications 3 in-lb/sq. ft. Parallel blade, without edge seals, for non-tight close-off applications 4 in-lb/sq. ft. Opposed blade, with edge seals, for tight close-off applications 5 in-lb/sq. ft. Parallel blade, with edge seals, for tight close-off applications 7 in-lb/sq. ft.

The above torque loadings will work for most applications under 2 in. w.g. static pressure or 1000 FPM face velocity. For applications between this criteria and 3 in. w.g. or 2500 FPM, the torque loading should be increased by a multiplier of 1.5. If the application calls for higher criteria up to 4 in. w.g. or 3000 FPM, use a multiplier of 2.0.

General Information

Trane actuators should be mounted indoors in a dry, relatively clean environment free from corrosive fumes. If the actuator is to be mounted outdoors, a protective enclosure must be used to shield the actuator. For new construction work, order dampers with extended shafts. Instruct the installing contractor to allow space for mounting and service of the actuator on the shaft. The damper shaft must extend at least 3 1/2" from the duct. If the shaft extends less than 3-1/2" or if an obstruction blocks access, the shaft can be extended with the AV 10-18 shaft extension accessory or the actuator may be mounted in its short shaft configuration.

Installation Instructions

Mechanical Installation

adequate shaft length, slide the actuator over the shaft with the side marked “CCW” (or the “CW” side if this is the side with the clamp). If the shaft extends at least 1/8” through the clamp, mount the actuator as follows. If not, go to the Short Shaft Installation section.

Figure A Universal Clamp and IND-AF2 Pointer (optional) Positions Indicating Fail-Safe and Pre-load Settings

3. If the clamp is not on the correct side as determined in step #1, re-mount the clamp as follows. If it is on the correct side, proceed to step #5. Look at the universal clamp. If you are mounting the actuator with the “CCW” side out, position the clamp so that the pointer section of the tab is pointing to 0° (see Fig. C) and the spline pattern of the clamp mates with spline of the actuator. Slip the clamp over the spline. (Use the same procedure if the “CW” side is out.) If your application requires a mechanical minimum position, read the Rotation Limiting, Mechanical Minimum Damper Position section on page 21.

4. Lock the clamp to the actuator using the retaining clip.

5. Verify that the damper is still in its full fail-safe position.

6. Slide the actuator over the shaft.

7. Position the actuator in the desired location.

8. Tighten the two nuts on the clamp using a 10mm wrench or socket using 6-8 ft-lb of torque.

9. Slip the stud of the anti rotation strap into the slot at the base of the actuator. The stud should be positioned approximately 1/16 of an inch from the closed end of the slot. Bend the strap as needed to reach the duct. Attach the strap to the duct with #8 self tapping screws.

Short Shaft Installation

If the shaft extends at least 3/4” from the duct, follow these steps:

1. Determine the best orientation for the universal clamp on the back of the actuator. The best location would be where you have the easiest access to the V bolt nuts on the clamp.

2. Engage the clamp to the actuator as close as possible to the determined location.

3. Lock the clamp in place using the remaining retainer clip.

4. Verify that the damper is still in its full fail-safe position.

5. Slide the actuator over the shaft.

6. Position the actuator in the desired location.

7. Tighten the two nuts on the clamp using a 10mm wrench or socket using 6-8 ft-lb of torque.

8. Slip the stud of the anti-rotation strap into the slot at the base of the actuator. The stud should be positioned approximately 1/16 of an inch from the closed end of the slot. Bend the strap as needed to reach the duct. Attach the strap to the duct with #8 self tapping screws.

9. If damper position indication is required, use the optional IND-AF2 pointer. See Figure A.

Jackshaft Installation

The TAF… series actuator is designed for use with jackshafts up to 1.05” in diameter. In most applications, the TAF actuator may be mounted in the same manner as a standard damper shaft application. If more torque is required than one TAF actuator can provide, a second TAF actuator may be mounted to the jackshaft using the ZG-102 multiple actuator mounting bracket. See wiring guide for wiring details.

Multiple Actuator Mounting

If more torque is required than one TAF actuator can provide, a second TAF actuator may be mounted to the shaft using the ZG-102 multiple mounting bracket. Notes:The manual positioning mechanism cannot be used in

multiple actuator applications.

Special Wiring and Additional Information: See wiring guide

Rotation Limitation

The angle of rotation limiter, ZDB-AF2, is used in conjunction with the tab on the universal clamp or IND-AF2 position indicator which comes with the ZDB-AF2. In order to function properly, the clamp or indicator must be mounted correctly. See Figure A.

The ZDB-AF2 may not work in certain mounting orientations using the ZG-106 or ZG-107 mounting brackets. It will not work with the ZG-108 mounting bracket. Limiting the damper rotation must be accomplished by adjusting the crankarm linkage.

The ZDB-AF2 may be used in 2 ways to control the rotational output of the TAF series actuator. One use is in the application where a damper has a designed rotation less than 90°. An example would be a 45° or 60° rotating damper. The other application would be to set a minimum damper position which can be easily set or changed without having to remove the actuator from the damper.

Damper Rotation Limiting

1. Determine the amount of damper rotation required.

2. Locate the Angle of Rotation Limiter (ZDB-AF2) on the actuator so that its edge lines up with the degree graduation on the actuator face which corresponds with the required rotation. See Figure C.

3. Find the appropriate cross-hair location through the slot of the limiter. This is the screw mounting location.

4. Pierce through the label material to allow easy fastening of the retaining screw.

5. Position the limiter back to the desired position, making sure the locating “teeth” on the limiter are engaged into the locating holes on the actuator.

6. Fasten the limiter to the actuator using the self tapping screw provided.

7. Test the damper rotation either manually with the manual crank or apply power and if required, a control signal. Re-adjust if necessary.

Mechanical Minimum Damper Position

In order to use this procedure, the actuator must be mounted for short shaft mounting. See page 20.

1. Position the damper to its minimum position by using the manual crank or by providing the appropriate control signal to the TAF24… modulating type actuator.

2. Place the indicator on to the actuator spline in the approximate position shown in Figure D. Fasten it with the retaining clip. Note that the mounting orientation is different than the mounting used for Damper Rotation Limiting.

3. Place the ZDB-AF2 rotation limiter on the actuator so that it either makes contact with, or is as close as possible to, the edge of the indicator. See Figure E. Make sure that the locating teeth are engaged into the locating holes on the actuator. If all of the mounting teeth do not align with the holes, the mounting location of the indicator to the spline may have to be moved. The limiter would then be remounted to get the best position match of both parts.

4. Find the cross-hair location through the slot of the limiter. This is the screw mounting location.

5. Pierce through the label material to allow easy fastening of the retaining screw.

6. Fasten the limiter to the actuator using the self tapping screw provided.

7. Test the damper operation either manually with the manual crank or apply power and if required, a control signal. Re-adjust if necessary.

Installation Instructions

This method should not be used for outside air damper applications. The damper will never go to the full close-off position. This may cause coils to freeze or other system problems. The TAF24-SR wired to either the SGA24 or SGF24 can be used for minimum position setting and still provide full close-off.

Manual Override

The TAF series actuators can be manually positioned to ease installation or for emergency positioning.

1. The manual override will only work if no power is available to the actuator.

2. Insert the manual crank (shipped with the actuator) into the hexagon hole located on either side of the actuator. An illustration, located on the label, shows the location.

3. Turn the crank in the direction shown on the label (clockwise on the “CW” side, counterclockwise on the “CCW” side). It will take approximately 19 revolutions to rotate the full 95° of rotation.

4. To lock the actuator in the required position, rotate the crank quickly in the opposite direction, 1/2 of a revolution. The “lock closed” icon on the label shows the correct direction.

5. The manual override may be disengaged in 2 ways.

- Rotate the crank about a 1/4 revolution in the same direction as the initial winding. The “lock open” icon shows the correct direction.

- Apply power to wire 1 and 2. The actuator will automatically disengage the override function and will go to the “on” position in the case of the on-off versions. Or, in the case of the proportional versions, go to the 0 signal position and then go to the position corresponding to the control signal. The actuator will now work normally.

Testing the Installation without Power

The actuator/damper installation may be tested without power at the actuator. Refer to the manual positioning section of the instructions. Move the damper to its full non-fail-safe position using the manual crank. Disengage the manual position mechanism and have the damper go to full fail-safe position. Correct any mechanical problems and retest.

Auxiliary Switches

The TAF series actuators may be ordered with 2 built-in SPDT auxiliary switches used for safety interfacing or signalling, for example, for fan start-up. The switch position near the fail-safe position is fixed at 5°. The other is adjustable between 25 and 85° of rotation. The crank, supplied with the actuator, or a 3mm allen wrench is used to adjust the switching position.

Switch Rating

Voltage Resistive Load Inductive Load 120 VAC 7A 5A 250 VAC 7A 2.5A

Two methods may be used to adjust the switching point of the adjustable switch.

Method 1 - See Figure F 1 The actuator must be in its fail-safe position.

2. Insert the crank into the hexagon shaped hole located in the center of the adjustable switch pointer.

3. Rotate the crank until the switch pointer is at the desired switch point in degrees as shown.

Method 2 - See Figure G

1. Position the damper to the point at which you want the switch to activate. This may be done by using the manual override or by providing the appropriate proportional signal to TAF24… modulating type actuator. The position of the switch pointer is not important during this step.

2. Insert the crank into the hexagon shaped hole located in the center of the adjustable switch pointer.

3. Rotate the switch pointer to just past the switch point indicating arrow as shown.

Installation Instructions

Electrical Operation

General

The TAF series actuators utilize brushless DC motor technology. The TAF uses this motor in conjunction with an Application Specific Integrated Circuit (ASIC). In the On-Off versions of the TAF, the ASIC monitors and controls the actuator’s rotation and a digital rotation sensing function to prevent damage to the actuator. The TAF24… modulating type actuators incorporate a built in microprocessor. The microprocessor provides the intelligence to the ASIC to provide a constant rotation rate and knows the actuator’s exact zero position.

Brushless DC Motor Operation

A brushless DC motor spins by reversing the poles of stationary electromagnets housed inside of a rotating permanent magnet. The electromagnetic poles are switched by a special ASIC circuit. Unlike the conventional DC motor, there are no brushes to wear or commutators to foul.

Overload Protection

The TAF series actuators are protected from overload at all angles of rotation. The ASIC circuit constantly monitors the rotation of the DC motor inside the actuator and stops the pulses to the motor when it senses a stall condition. The DC motor remains energized and produces full rated torque to the load. This helps ensure that dampers are fully closed and that edge and blade seals are always properly compressed.

Motor Position Detection

The brushless DC motors eliminate the need for potentiometers for positioning in modulating type actuators. Inside the motor are three “Hall Effect” sensors. These sensors detect the spinning rotor and send pulses to the microprocessor which counts the pulses and calculates the position to within 1/3 of a revolution of the motor.

TAF24-SR actuators have built-in brushless DC motors which provide better accuracy and longer service life.

The TAF24-SR actuators are designed with a unique non-symmetrical deadband. The actuator follows an increasing or decreasing control signal with a 80 mV resolution. If the signal changes in the opposite direction, the actuator will not respond until the control signal changes by 200 mV. This allows these actuators to track even the slightest deviation very accurately, yet allowing the actuator to “wait” for a much larger change in control signal due to control signal instability.

General Wiring Instructions

WARNING The wiring technician must be trained and experienced with electronic circuits. Disconnect power supply before attempting any wiring connections or changes. Make all connections in accordance with wiring diagrams and follow all applicable local and national codes. Provide disconnect and overload protection as required. Use copper, twisted pair, conductors only. If using electrical conduit, the attachment to the actuator must be made with flexible conduit.

Always read the controller manufacturer's installation literature carefully before making any connections. Follow

all instructions in this literature. If you have any questions, contact the controller manufacturer.

Transformer(s)

The TAF24 . . actuators require a 24 VAC class 2 transformer and draws a maximum of 10 VA per actuator. The actuator enclosure cannot be opened in the field, there are no parts or components to be replaced or repaired.

– EMC directive: 89/336/EEC – Software class A: Mode of operation type 1 – Low voltage directive: 73/23/EEC

CAUTION: It is good practice to power electronic or digital controllers from a separate power transformer than that used for actuators or other end devices. The power supply design in our actuators and other end devices use half wave rectification. Some controllers use full wave rectification. When these two different types of power supplies are connected to the same power transformer and the DC commons are connected together, a short circuit is created across one of the diodes in the full wave power supply, damaging the controller. Only use a single power transformer to power the controller and actuator if you know the controller power supply uses half wave rectification.

Multiple Actuators, One Transformer

Multiple actuators may be powered from one transformer provided the following rules are followed:

1. The TOTAL current draw of the actuators (VA rating) is less than or equal to the rating of the transformer.

2. Polarity on the secondary of the transformer is strictly followed. This means that all No. 1 wires from all

actuators are connected to the common leg on the transformer and all No. 2 wires from all actuators are connected to the hotleg. Mixing wire No. 1 & 2 on one leg

of the transformer will result in erratic operation or failure of the actuator and/or controls.

Multiple Actuators, Multiple Transformers

Multiple actuators positioned by the same control signal may be powered from multiple transformers provided the following rules are followed:

1. The transformers are properly sized.

2. All No. 1 wires from all actuators are tied together and tied to the negative leg of the control signal. See wiring diagram.

Keep power wire runs below the lengths listed in the Figure H. If more than one actuator is powered from the same wire run, divide the allowable wire length by the number of actuators to determine the maximum run to any single actuator. Example: 3 actuators, 16 Ga wire

350 ft ÷ 3 Actuators = 117 ft. maximum wire run

Maximum Wire Length:

Wire Size Max. Feet. Wire Size Max. Feet

12 Ga 900 Ft. 18 Ga 225 Ft. 14 Ga 550 Ft. 20 Ga 125 Ft. 16 Ga 350 Ft. 22 Ga 60 Ft.

Wire Type and Wire Installation Tips

For most installations, 18 or 16 Ga. cable works well with the TAF24. . actuators. Use code-approved wire nuts, terminal strips or solderless connectors where wires are joined. It is good practice to run control wires unspliced from the actuator to the controller. If splices are unavoidable, make sure the splice can be reached for possible maintenance. Tape and/or wire-tie the splice to reduce the possibility of the splice being inadvertently pulled apart.

The TAF24… proportional actuators have a digital circuit that is designed to ignore most unwanted input signals (pickup). In some situations the pickup may be severe enough to cause erratic running of the actuator. For example, a large inductive load (high voltage AC wires, motors, etc.) running near the power or control wiring may cause excessive pickup. To solve this problem, make one or more of the following changes:

1. Run the wire in metallic conduit.

2. Re-route the wiring away from the source of pickup.

3. Use shielded wire (Belden 8760 or equal). Ground the

shield to an earth ground. Do not connect it to the actuator common.

Initialization of the TAF24-SR

When power is initially applied, the actuator will first release its manual preload position (This assumes a manual position has been set). The actuator will then rotate to the full fail-safe position. At this point the microprocessor recognizes that the actuator is at full fail-safe and uses this position as the base for all of its position calculations. The microprocessor will retain the initialized zero during short power failures of up to 20 seconds. For power failures greater than 20 seconds, the actuator would naturally return to its full fail-safe position prior to the microprocessor losing its memory. The actuator will also re-initialize if the manual position mechanism is used.

Procedure

Control signal is applied to actuator.

Check power wiring. Correct any problems. See Note 1.

Turn reversing switch to the correct position. Make sure the switch is turned all the way left or right.

Make sure the control signal positive (+) is connected to Wire No 3 and control signal negative (-) is connected to wire No. 1. Most control problems are caused by reversing these two wires. Verify that the reversing switch is all the way CCW or CW.

Check input signal with a digital volt meter (DVM). Make sure the input is within the range of the actuator. For TAF24-SR this is 2 to 10 VDC or 4 to 20 mA. Note: The input signal must be above the 2 VDC or 4 mA to have the actuator move.

Loosen the nuts on the V-bolt and move the damper by hand from fully closed to fully open.

Check damper torque requirement.

Actuator works properly. Test controller by following controller manufacturer's instructions.

Expected Response

Actuator will move to its “Control Signal” position.

Mechanical Installation

Standard Mounting

Mechanical Operation

The actuator is mounted directly to a damper shaft up to 1.05” in diameter by means of its universal clamp. A crank arm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft.

The TNF series actuators provide true spring return operation for reliable fail-safe application and positive close-off on air tight dampers. The spring return system provides consistent torque to the damper with, and without, power applied to the actuator.

The TNF series provides 95° of rotation and is provided with a graduated position indicator showing 0° to 95°. The TNF…-S versions are provided with one built-in auxiliary switch. This SPDT switch is provided for safety interfacing or

signaling, for example, for fan start-up. The switching function is adjustable between 5° and 85°.

1. See Fig. B. Manually move the damper to the fail-safe position (a) (usually closed). If the shaft rotated counterclockwise ( ), this is a CCW installation. If the shaft rotated clockwise ( ), this is a CW installation. In a CCW installation, the actuator side marked “CCW” faces out, while in a CW installation, the side marked “CW” faces out. All other steps are identical.

2. The actuator is usually shipped with the universal clamp mounted to the “CCW” side of the actuator. To test for adequate shaft length, slide the actuator over the shaft with the side marked “CCW” (or the “CW” side if this is the side with the clamp). If the shaft extends at least 1/8” through the clamp, mount the actuator as follows. If not, go to the Short Shaft Installation section.

Determining Torque Loading and Actuator Sizing

Damper torque loadings, used in selecting the correct size actuator, should be provided by the damper manufacturer. If this information is not available, the following general selection guidelines can be used.

Damper Type Torque Loading

Opposed blade, without edge seals, for non-tight close-off applications 3 in-lb/sq. ft. Parallel blade, without edge seals, for non-tight close-off applications 4 in-lb/sq. ft. Opposed blade, with edge seals, for tight close-off applications 5 in-lb/sq. ft. Parallel blade, with edge seals, for tight close-off applications 7 in-lb/sq. ft.

The above torque loadings will work for most applications under 2 in. w.g. static pressure or 1000 FPM face velocity. For applications between this criteria and 3 in. w.g. or 2500 FPM, the torque loading should be increased by a multiplier of 1.5. If the application calls for higher criteria up to 4 in. w.g. or 3000 FPM, use a multiplier of 2.0.

General Information

Trane actuators should be mounted indoors in a dry, relatively clean environment free from corrosive fumes. If the actuator is to be mounted outdoors, a protective enclosure must be used to shield the actuator. For new construction work, order dampers with extended shafts. Instruct the installing contractor to allow space for mounting and service of the actuator on the shaft. The damper shaft must extend at least 3 1/2" from the duct. If the shaft extends less than 3 1/2" or if an obstruction blocks access, the shaft can be extended with the AV 10-18 shaft extension or the actuator may be mounted in its short shaft configuration.

3. If the clamp is not on the correct side as determined in step #1, re-mount the clamp as follows. If it is on the correct side, proceed to step #5. Look at the universal clamp. If you are mounting the actuator with the “CCW” side out, position the clamp so that the pointer section of the tab is pointing to 0° (see Fig. C) and the spline pattern of the clamp mates with spline of the actuator. Slip the clamp over the spline. (Use the same procedure if the “CW” side is out.) If your application requires a mechanical minimum position, read the Rotation Limitation section.

4. Lock the clamp to the actuator using the retaining clip.

5. Verify that the damper is still in its full fail-safe position (a).

6. Mount the spring return actuator to the shaft. Tighten the universal clamp, finger tight only.

7. Mount the anti-rotation strap at the base of the actuator. Slip the stop of the anti-rotation strap in the slot of the base of the actuator. The stud should be centered approximately 1/4” from the end of the slot. Do not tighten the screws.

8. Remove the screw from one end of the mounting bracket and pivot it away from the actuator.

9. Loosen the universal clamp and, making sure not to move the damper shaft, rotate the actuator approximately 5° in the direction which would open the damper.

10. Tighten the universal clamp to the shaft.

11. Rotate the actuator to apply pressure to the damper seals (b) and re-engage the anti-rotation strap (c).

12. Tighten all fasteners.

Short Shaft Installation

If the shaft extends at least 3/4” from the duct, follow these steps:

1. Move damper blades to the fail-safe position (a).

2. Determine the best orientation for the universal clamp on the back of the actuator. The best location would be where you have the easiest access to the V bolt nuts on the clamp.

3. Engage the clamp to the actuator as close as possible to the determined location.

4. Lock the clamp to the actuator using the retainer clip.

5. Mount the spring return actuator to the shaft. Tighten the universal clamp, finger tight only.

6. Mount the anti-rotation strap at the base of the actuator. Do not tighten the screws.

7. Remove the screw from one end of the mounting bracket and pivot it away from the actuator.

8. Loosen the universal clamp and, making sure not to move the damper shaft, rotate the actuator approximately 5° in the direction which would open the damper.

9. Verify that the damper is still in its full fail-safe position.

10. Tighten the universal clamp to the shaft.

11. Rotate the actuator to apply pressure to the damper seals (b) and re-engage the anti-rotation strap (c).

Mechanical Installation

Rotation Limitation

The angle of rotation limiter, ZDB-AF2, is used in conjunction with the tab on the universal clamp or IND-AF2 position indicator which comes with the ZDB-AF2. In order to function properly, the clamp or indicator must be mounted correctly. See Fig. A.

The ZDB-AF2 may not work in certain mounting orientations using the ZG-106 or ZG-107 mounting brackets. It will not work with the ZG-108 mounting bracket. Limiting the damper rotation must be accomplished by adjusting the crank arm linkage.

The ZDB-AF2 may be used to control the rotational output of the TNF series actuator where a damper has a designed rotation less than 90°. An example would be a 45° or 60° rotating damper.

Damper Rotation Limiting

1. Determine the amount of damper rotation required.

2. Locate the Angle of Rotation Limiter (ZDB-AF2) on the actuator so that its edge lines up with the degree graduation on the actuator face which corresponds with the required rotation. See Figure. C.

3. Find the appropriate cross-hair location through the slot of the limiter. This is the screw mounting location.

4. Pierce through the label material to allow easy fastening of the retaining screw.

5. Position the limiter back to the desired position, making sure the locating “teeth” on the limiter are engaged into the locating holes on the actuator.

6. Fasten the limiter to the actuator using the self tapping screw provided.

7. Test the damper rotation before applying power and if required, a control signal. Re-adjust if necessary.

Auxiliary Switches

The TNF series actuators may be ordered with one built-in SPDT auxiliary switch used for safety interfacing or signalling, for example, for fan start-up. The switch position is adjustable between 5° and 85° of rotation. The crank, supplied with the actuator, or a 3mm allen wrench is used to adjust the switching position. See Figure. D.

1 The actuator must be in its fail-safe position.

2. Insert the crank into the hexagon shaped hole located in the center of the adjustable switch pointer.

3. Rotate the crank until the switch pointer is at the desired switch point in degrees as shown.

Installation Instructions

Initialization of the TNF24-SR

When power is initially applied, the microprocessor recognizes that the actuator is at full fail-safe and uses this position as the base for all of its position calculations. The microprocessor will retain the initialized zero during short power failures of up to 20 seconds. For power failures greater than 20 seconds the actuator would naturally return to it full fail-safe position prior to the microprocessor losing its memory. When power is applied again, the actuator will re-initialize the zero position. The microprocessor will keep count of these short power failures until 16 occur. At this point, the microprocessor will automatically drive the actuator to its zero position and re-initialize to correct for any possible error accumulation.

Motor Position Detection

A brushless DC motors eliminate the need for potentiometers for positioning. Inside the motor are three “Hall Effect” sensors. These sensors detect the spinning rotor and send pulses to the microprocessor which counts the pulses and calculates the position to within 1/3 of a revolution of the motor.

Overload Protection

The TNF24-SR actuators are protected from overload at all angles of rotation. The on board microprocessor constantly monitors the rotation of the DC drive motor inside the actuator and stops the pulses to the motor when it senses a stall condition. The DC motor remains energized and produces full rated torque to the load. This helps ensure that dampers are fully closed and that edge and blade seals are always properly compressed.

Brushless DC Motor Operation

The brushless DC motor spins by reversing the poles of stationary electromagnets housed inside rotating permanent magnets. The electromagnetic poles are switched by a microprocessor and a special ASIC (Application Specific Integrated Circuit). Unlike the conventional DC motor, there are no brushes to wear or commutators to foul.

TNF actuator responds to a 200 mV signal when reversing direction from stop position.

TNF24-SR actuators have built-in brushless DC motors which provide better accuracy and longer service life. The TNF24-SR actuators are designed with a unique non-symmetrical deadband. The actuator follows an increasing or

decreasing control signal with a 80 mV resolution. If the signal changes in the opposite direction, the actuator will not respond until the control signal changes by 200 mV. This allows these actuators to track even the slightest deviation very accurately, yet allowing the actuator to “wait” for a much larger change in control signal due to control signal instability.

Control Accuracy and Stability

40

I20683 - Subject to change.

WARNING The wiring technician must be trained and experienced with electronic circuits. Disconnect power supply before attempting any wiring connections or changes. Make all connections in accordance with wiring diagrams and follow all applicable local and national codes. Provide disconnect and overload protection as required. Use copper, twisted pair, conductors only. If using electrical conduit, the attachment to the actuator must be made with flexible conduit.

Always read the controller manufacturer's installation literature carefully before making any connections. Follow

all instructions in this literature. If you have any questions, contact the controller manufacturer.

Transformer(s)

The TNF24 . . actuator requires a 24 VAC class 2 transformer and draws a maximum of 10 VA per actuator. The actuator enclosure cannot be opened in the field, there are no parts or components to be replaced or repaired.

– EMC directive: 89/336/EEC – Software class A: Mode of operation type 1 – Low voltage directive: 73/23/EEC

CAUTION: It is good practice to power electronic or digital controllers from a separate power transformer than that used for actuators or other end devices. The power supply design in our actuators and other end devices use half wave rectification. Some controllers use full wave rectification. When these two different types of power supplies are connected to the same power transformer and the DC commons are connected together, a short circuit is created across one of the diodes in the full wave power supply, damaging the controller. Only use a single power transformer to power the controller and actuator if you know the controller power supply uses half wave rectification.

Multiple Actuators, One Transformer

Multiple actuators may be powered from one transformer provided the following rules are followed:

1. The TOTAL current draw of the actuators (VA rating) is less than or equal to the rating of the transformer.

2. Polarity on the secondary of the transformer is strictly followed. This means that all No. 1 wires from all

actuators are connected to the common leg on the transformer and all No 2 wires from all actuators are connected to the hotleg. Mixing wire No. 1 & 2 on one leg

of the transformer will result in erratic operation or failure of the actuator and/or controls.

Multiple Actuators, Multiple Transformers

Multiple actuators positioned by the same control signal may be powered from multiple transformers provided the following rules are followed:

1. The transformers are properly sized.

2. All No. 1 wires from all actuators are tied together and tied to the negative leg of the control signal. See wiring diagram page 19.

Wire Length for TNF… Actuators

Keep power wire runs below the lengths listed in the table in Figure E. If more than one actuator is powered from the same wire run, divide the allowable wire length by the number of actuators to determine the maximum run to any single actuator. Example for TNF24-SR:

3 actuators, 16 Ga wire 550 ft ÷ 3 actuators = 183 ft. maximum wire run

Maximum wire length:

Wire Size Max. Feet. Wire Size Max. Feet

12 Ga 1100 Ft. 18 Ga 260 Ft. 14 Ga 700 Ft. 20 Ga 140 Ft. 16 Ga 440 Ft. 22 Ga 75 Ft.

Figure E

Wire Type and Wire Installation Tips

For most installations, 18 or 16 Ga. cable works well with the TNF24… actuators. Use code-approved wire nuts, terminal strips or solderless connectors where wires are joined. It is good practice to run control wires unspliced from the actuator to the controller. If splices are unavoidable, make sure the splice can be reached for possible maintenance. Tape and/or wire-tie the splice to reduce the possibility of the splice being inadvertently pulled apart.

The TNF24… proportional actuators have a digital circuit that is designed to ignore most unwanted input signals (pickup). In some situations the pickup may be severe enough to cause erratic running of the actuator. For example, a large inductive load (high voltage AC wires, motors, etc.) running near the power or control wiring may cause excessive pickup. To solve this problem, make one or more of the following changes:

1. Run the wire in metallic conduit.

2. Re-route the wiring away from the source of pickup.

3. Use shielded wire (Belden 8760 or equal). Ground the

shield to an earth ground. Do not connect it to the actuator common.

Procedure

Control signal is applied to actuator.

Check power wiring. Correct any problems. See Note 1.

Turn reversing switch to the correct position. Make sure the switch is turned all the way left or right.

Make sure the control signal positive (+) is connected to Wire No 3 and control signal negative (-) is connected to wire No. 1. Most control problems are caused by reversing these two wires. Verify that the reversing switch is all the way CCW or CW.

Check input signal with a digital volt meter (DVM). Make sure the input is within the range of the actuator. For TNF24-SR this is 2 to 10 VDC or 4 to 20 mA. Note: The input signal must be above the 2 VDC or 4 mA to have the actuator move.

Loosen the nuts on the V-bolt and move the damper by hand from fully closed to fully open.

Check damper torque requirement.

Actuator works properly. Test controller by following controller manufacturer's instructions.

Expected Response

Actuator will move to its “Control Signal” position.

TLF24 (-S)

On-off, Spring Return Fail-Safe, 24 V

Torque min. 35 in-lb, for control of air dampers

Application

For on-off, fail-safe control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications. Control is on-off from an auxiliary contact, digital output, or a manual switch.

The actuator is mounted directly to a damper shaft from 3/8” up to 1/2” in diameter by means of its universal clamp, 1/2” shaft centered at delivery. For shafts up to 3/4” use K6-1 accessory. A crank arm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft.

Operation

The TLF series actuators provide true spring return operation for reliable fail-safe application and positive close off on air tight dampers. The spring return system provides consistent torque to the damper with, and without, power applied to the actuator. The TLF series provides 95° of rotation and is provided with a graduated position indicator showing 0° to 95°. The actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches. Power consumption is reduced in holding mode.

The TLF24-S version is provided with one built in auxiliary switch. This SPDT switch is provided for safety interfacing or signaling, for example, for fan start-up. The switching function is adjustable between 0° and 95°. The auxiliary switch in the TLF24-S is double insulated so an electrical ground connection is not necessary.

Torque min. 35 in-lb, for control of air dampers

Application

For proportional modulation of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications.

The actuator is mounted directly to a damper shaft from 3/8” up to 1/2” in diameter by means of its universal clamp, 1/2” shaft centered at delivery. For shafts up to 3/4” use K6-1 accessory. A crank arm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft.

The actuator operates in response to a 2 to 10 VDC, or with the addition of a 500Ω resistor, a 4 to 20 mA control input from an electronic controller or positioner. A 2 to 10 VDC feedback signal is provided for position indication or master-slave applications.

Operation

The TLF series actuators provide true spring return operation for reliable fail-safe application and positive close-off on air tight dampers. The spring return system provides consistent torque to the damper with, and without, power applied to the actuator.

The TLF series provides 95° of rotation and is provided with a

graduated position indicator showing 0° to 95°. The TLF24-SR uses a brushless DC motor which is controlled

by an Application Specific Integrated Circuit (ASIC) and a microprocessor. The microprocessor provides the intelligence to the ASIC to provide a constant rotation rate and to know the actuator’s exact fail-safe position. The ASIC monitors and controls the brushless DC motor’s rotation and provides a digital rotation sensing function to prevent damage to the actuator in a stall condition. The actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches. Power consumption is reduced in holding mode.

For all accessories, see pages 110 and 132.

Preliminary Steps

1. Actuators should be mounted indoors in dry, relatively clean environment free from corrosive fumes. If the actuator is to be mounted outdoors, a protective enclosure must be used to shield the actuator.

2. For new construction work, order dampers with extended shafts. Instruct the installing contractor to allow space for mounting and service of the actuator on the shaft.

3. For standard mounting, the damper shaft must extend at least 3 1/2" from the duct. If the shaft extends less than 3 1/2", the actuator may be mounted in its short shaft configuration. If an obstruction blocks access, the shaft can be extended with the AV 10-18 shaft extension (K6-1 is required).

Installation Instructions

Quick-Mount Visual Instructions

1. Rotate the damper to its failsafe position. If the shaft rotates counterclockwise, mount the “CCW” side of the actuator out. If it rotates clockwise, mount the actuator with the “CW” side out.

2. If the universal clamp is not on the correct side of the actuator, move it to the correct side.

3. Slide the actuator onto the shaft and tighten the nuts on the V-bolt with a 10 mm wrench to 6-8 ft-lb of torque.

4. Slide the anti-rotation strap under the actuator so that it engages the slot at the base of the actuator. Secure the strap to the duct work with #8 self-tapping screws.

NOTE: Read the “Standard Mounting” instructions, on the next

page, for more detailed information.

TLF

1. See Figue. B. Manually move the damper to the fail-safe position (a) (usually closed). If the shaft rotated counterclockwise ( ), this is a CCW installation. If the shaft rotated clockwise ( ), this is a CW installation. In a left hand installation, the actuator side marked “CW” faces out, while in a CW installation, the side marked “CCW” faces out. All other steps are identical.

2. The actuator is usually shipped with the universal clamp mounted to the “CW” side of the actuator. To test for adequate shaft length, slide the actuator over the shaft with the side marked “CW” (or the “CCW” side if this is the side with the clamp). If the shaft extends at least 1/8” through the clamp, mount the actuator as follows. If not, go to the Short Shaft Installation section.

3. If the clamp is not on the correct side as determined in step #1, re-mount the clamp as follows. If it is on the correct side, proceed to step #5. Look at the universal clamp. If you are mounting the actuator with the “CCW” side out, position the clamp so that the pointer section of the tab is pointing to 0° (see Figure. C) and the spline pattern of the clamp mates with spline of the actuator. Slip the clamp over the spline. (Use the same procedure if the “CW” side is out.)

4. Lock the clamp to the actuator using the retaining clip.

5. Verify that the damper is still in its full fail-safe position (a).

6. Mount the spring return actuator to the shaft. Tighten the universal clamp, finger tight only.

7. Mount the anti-rotation strap at the base of the actuator. Do not tighten the screws.

8. Remove the screw from one end of the mounting bracket and pivot it away from the actuator.

9. Loosen the universal clamp and, making sure not to move the damper shaft, rotate the actuator approximately 5° in the direction which would open the damper.

10. Tighten the universal clamp to the shaft.

11. Rotate the actuator to apply pressure to the damper seals (b) and re-engage the anti-rotation strap (c).

12. Tighten all fasteners.

Installation Instructions

Standard Mounting / Airtight Damper Procedure

Mechanical Operation

The actuator is mounted directly to a damper shaft up to 1/2” in diameter by means of its universal clamp, or up to a 3/4” shaft with the optional K6-1 clamp. A crank arm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft.

The TLF series actuators provide true spring return operation for reliable fail-safe application and positive close-off on air tight dampers. The spring return system provides consistent torque to the damper with, and without, power applied to the actuator.

The TLF series provides 95° of rotation and is provided with a graduated position indicator showing 0° to 95°. The TLF…-S versions are provided with one built-in auxiliary switch. This SPDT switch is provided for safety interfacing or

signaling, for example, for fan start-up. The switching function is adjustable between 0° and 95°.

If the shaft extends at least 3/4” from the duct, follow these steps:

1. See Figure D. Move damper blades to the fail-safe position (a).

2. Determine the best orientation for the universal clamp on the back of the actuator. The best location would be where you have the easiest access to the V bolt nuts on the clamp.

3. Engage the clamp to the actuator as close as possible to the determined location.

4. Lock the clamp to the actuator using the retainer clip.

5. Mount the spring return actuator to the shaft. Tighten the universal clamp, finger tight only.

6. Mount the anti-rotation strap at the base of the actuator. Do not tighten the screws.

7. Remove the screw from one end of the mounting bracket and pivot it away from the actuator.

8. Loosen the universal clamp and, making sure not to move the damper shaft, rotate the actuator approximately 5° in the direction which would open the damper.

9. Verify that the damper is still in its full fail-safe position.

10. Tighten the universal clamp to the shaft.

11. Rotate the actuator to apply pressure to the damper seals (b) and re-engage the anti-rotation strap (c).

13. Use IND-LF accessory if position indication is needed.

Installation Instructions

Short Shaft Mounting with IND-LF Position Indicator / Airtight Damper Procedure

Initialization of the TLF24-SR

When power is applied, the internal microprocessor recognizes that the actuator is at its full fail-safe position and uses this position as the base for all of its position calculations. This procedure takes approximately 15 seconds. During this time you will see no response at the actuator. The microprocessor will retain the initialized zero during short power failures of up to 25 seconds. When power is applied during this period, the actuator will return to normal operation and proceed to the position corresponding to the input signal provided. For power failures over 25 seconds, the actuator will be at it fail-safe position and will go through the start up initialization again.

Motor Position Detection

A Brushless DC motors eliminate the need for potentiometers for positioning. Inside the motor are three “Hall Effect” sensors. These sensors detect the spinning rotor and send pulses to the microprocessor which counts the pulses and calculates

the position to within 1/3 of a revolution of the motor.

Overload Protection

The TLF, on-off actuators are electronically protected against overload. The TLF, On-off actuators have an internal current limiter which maintains the current at a safe level which will not damage the actuator while providing adequate holding torque.

The TLF24, modulating actuators (TLF24-SR, TLF24-3) are protected against overload by digital technology located in the ASIC. The ASIC circuitry constantly monitors the rotation of the brushless DC motor inside the actuator and stops the pulsing to the motor when it senses a stall condition. The motor remains energized and produces full rated torque during stall conditions. The actuator will try to move in the direction of the stall every 2 minutes, for a period of 32 minutes. After this, the actuator will try again every 2 hours .

TLF

The TLF actuators are provided with an adjustable stop to limit the rotation of the actuator. This function works in conjunction with the universal clamp or the optional position indicator. The adjustable stop is needed when rotation of less than 95° is required. The TLF actuator can be indefinitely stalled, in any position, without harming the actuator.

Using the Universal Clamp:

1. Loosen the end stop fastening screw using a #2 Phillips screwdriver.

2. Move the stop block so the bottom edge of the block lines up with the number corresponding to the desired degrees of rotation (example: 45 degrees of rotation = .5).

3. Lock the block in place with the fastening screw.

4. Check the actuator for proper rotation.

Using the IND-LF Position Indicator with Adjustable Stop:

Note: Preferred method if short shaft mounting is used.

1. With the actuator in its fail-safe position, place the IND-LF position indicator so that it points to the 0° position.

2. Loosen the end stop fastening screw using a #2 Phillips screwdriver.

3. Move the stop block so the bottom edge of the block lines up with the number corresponding to the desired degrees of rotation (example: 45 degrees of rotation = .5).

Installation Instructions

Quick-Mount Visual Instructions for Mechanical Installation

TLF24-SR actuators have built-in brushless DC motors which provide better accuracy and longer service life. The TLF24-SR actuators are designed with a unique non-symmetrical deadband. The actuator follows an increasing or

decreasing control signal with a 80 mV resolution. If the signal changes in the opposite direction, the actuator will not respond until the control signal changes by 200 mV. This allows these actuators to track even the slightest deviation very accurately, yet allowing the actuator to “wait” for a much larger change in control signal due to control signal instability.

TLF actuator responds to a 80 mV signal when not changing direction from stop position.

TLF actuator responds to a 200 mV signal when reversing direction from stop position.

TLF24-3 and TLF24-SR actuators have a direction of rotation switch on the cover labeled “CW-CCW”. Switch position indicates start point. For the TLF24-SR, with the switch in position “CW”, the actuator rotates clockwise with a decrease in voltage or current. With the switch in position “CCW”, the actuator rotates counterclockwise with a decrease in voltage or current.

The TLF24-3 and TLF24-SR actuators rotate clockwise when the switch is in the “CW” position and power is applied to wire #3. When power is applied to wire #4 the actuator rotates counter clockwise.

Rotating the direction of rotation switch to “CCW” reverses the control logic.

During checkout, the switch position can be temporarily reversed and the actuator will reverse its direction. This allows the technician a fast and easy way to check the actuator operation without having to switch wires or change settings on the controller. When the check-out is complete, make sure

the switch is placed back to its original position.

Installation Instructions

The …-S model actuators are equipped with an adjustable auxiliary switch used to indicate damper position or to interface additional controls or equipment. Switching positions can be set over the full 0 to 95° rotation simply by setting a switch on the actuator.

1. Set desired switch position (Example 60%).

2. As the actuator rotates, the switch indicator moves from .6 (60%) toward 0 (0%). When the indicator passes 0 the switch contact between S1 and S2 is broken and the contact between S1 and S3 is made.

TLF

WARNING The wiring technician must be trained and experienced with electronic circuits. Disconnect power supply before attempting any wiring connections or changes. Make all connections in accordance with wiring diagrams and follow all applicable local and national codes. Provide disconnect and overload protection as required. Use copper, twisted pair, conductors only. If using electrical conduit, the attachment to the actuator must be made with flexible conduit.

Always read the controller manufacturer's installation literature carefully before making any connections. Follow

all instructions in this literature. If you have any questions, contact the controller manufacturer.

Transformer(s)

The TLF24 . . actuator requires a 24 VAC class 2 transformer and draws a maximum of 7 VA per actuator. The actuator enclosure cannot be opened in the field, there are no parts or components to be replaced or repaired.

– EMC directive: 89/336/EEC – Software class A: Mode of operation type 1 – Low voltage directive: 73/23/EEC

CAUTION: It is good practice to power electronic or digital controllers from a separate power transformer than that used for actuators or other end devices. The power supply design in our actuators and other end devices use half wave rectification. Some controllers use full wave rectification. When these two different types of power supplies are connected to the same power transformer and the DC commons are connected together, a short circuit is created across one of the diodes in the full wave power supply, damaging the controller. Only use a single power transformer to power the controller and actuator if you know the controller power supply uses half wave rectification.

Multiple Actuators, One Transformer

Multiple actuators may be powered from one transformer provided the following rules are followed:

1. The TOTAL current draw of the actuators (VA rating) is less than or equal to the rating of the transformer.

2. Polarity on the secondary of the transformer is strictly followed. This means that all No. 1 wires from all actuators

are connected to the common leg on the transformer and all No 2 wires from all actuators are connected to the hotleg. Mixing wire No. 1 & 2 on one leg of the transformer

will result in erratic operation or failure of the actuator and/or controls.

Multiple Actuators, Multiple Transformers

Multiple actuators positioned by the same control signal may be powered from multiple transformers provided the following rules are followed:

1. The transformers are properly sized.

2. All No. 1 wires from all actuators are tied together and tied to the negative leg of the control signal. See wiring diagram.

Wire Length for TLF… Actuators

Keep power wire runs below the lengths listed in the table in Figure A. If more than one actuator is powered from the same wire run, divide the allowable wire length by the number of actuators to determine the maximum run to any single actuator. Example for TLF24-SR:

3 actuators, 16 Ga wire 550 ft ÷ 3 actuators = 183 ft. maximum wire run

Maximum Wire Length:

Wire Size Max. Feet. Wire Size Max. Feet

12 Ga 1100 Ft. 18 Ga 260 Ft. 14 Ga 700 Ft. 20 Ga 140 Ft. 16 Ga 440 Ft. 22 Ga 75 Ft.

Figure A Wire Type and Wire Installation Tips

For most installations, 18 or 16 Ga. cable works well with the TLF24… actuators. Use code-approved wire nuts, terminal strips or solderless connectors where wires are joined. It is good practice to run control wires unspliced from the actuator to the controller. If splices are unavoidable, make sure the splice can be reached for possible maintenance. Tape and/or wire-tie the splice to reduce the possibility of the splice being inadvertently pulled apart.

The TLF24… proportional actuators have a digital circuit that is designed to ignore most unwanted input signals (pickup). In some situations the pickup may be severe enough to cause erratic running of the actuator. For example, a large inductive load (high voltage AC wires, motors, etc.) running near the power or control wiring may cause excessive pickup. To solve this problem, make one or more of the following changes:

1. Run the wire in metallic conduit.

2. Re-route the wiring away from the source of pickup.

3. Use shielded wire (Belden 8760 or equal). Ground the

shield to an earth ground. Do not connect it to the actuator common.

Brushless DC Motor Operation

The brushless DC motor spins by reversing the poles of stationary electromagnets housed inside rotating permanent magnets. The electromagnetic poles are switched by a microprocessor and a special ASIC (Application Specific Integrated Circuit). Unlike the conventional DC motor, there are no brushes to wear or commutators to foul.

Note 1 Check that the transformer(s) are sized properly.

• If a common transformer is used, make sure that polarity is observed on the secondary. This means connect all No. 1 wires to one leg of the transformer and all No. 2 wires to the other leg of the transformer.

• If multiple transformers are used with one control signal, make sure all No. 1 wires are tied together and tied to control signal negative (-).

• Controllers and actuators must have separate 24 VAC/VDC power sources.

Torque min. 18 in-lb, for control of air dampers

Application

For on-off, fail-safe control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications. Control is on-off from an auxiliary contact, or a manual switch.

The actuator is mounted directly to a damper shaft from 1/4” up to 1/2” in diameter by means of its universal clamp, 1/2” shaft centered at delivery. A crank arm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft.

Operation

The TTF series actuators provide true spring return operation for reliable fail-safe application and positive close off on air tight dampers. The spring return system provides consistent torque to the damper with, and without, power applied to the actuator. The TTF series provides 95° of rotation and is provided with a graduated position indicator showing 0° to 90°. The actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches. Power consumption is reduced in holding mode.

The TTF24-S versions are provided with one built-in auxiliary switch. This SPDT switch is provided for safety interfacing or signaling, for example, for fan start-up. The switching function is adjustable between 0° and 95°.

For all accessories, see pages 110 and 132.

I20683 - Subject to change.

1. See Figure B. Manually move the damper to the fail-safe position (a) (usually closed). If the shaft rotated counterclockwise ( ), this is a CCW installation. If the shaft rotated clockwise ( ), this is a CW installation. In a left hand installation, the actuator side marked “CW” faces out, while in a CW installation, the side marked “CCW” faces out. All other steps are identical.

2. The actuator is usually shipped with the universal clamp mounted to the “CW” side of the actuator. To test for adequate shaft length, slide the actuator over the shaft with the side marked “CW” (or the “CCW” side if this is the side with the clamp). If the shaft extends at least 1/8” through the clamp, mount the actuator as follows. If not, go to the Short Shaft Mounting section.

3. If the clamp is not on the correct side as determined in step #1, re-mount the clamp as follows. If it is on the correct side, proceed to step #5. Look at the universal clamp. If you are mounting the actuator with the “CCW” side out, position the clamp so that the pointer section of the tab is pointing to 0° (see Figure C) and the spline pattern of the clamp mates with spline of the actuator. Remount the stroke limiter to this side then slip the clamp over the spline. (Use the same procedure if the “CW” side is out.)

4. See Remounting the Stroke Limiter.

5. Lock the clamp to the actuator using the retaining clip.

6. Verify that the damper is still in its full fail-safe position (a).

7. Mount the spring return actuator to the shaft. Tighten the universal clamp, finger tight only.

8. Mount the anti-rotation strap at the base of the actuator. Do not tighten the screws.

9. Remove the screw from one end of the mounting bracket and pivot it away from the actuator.

10. Loosen the universal clamp making sure not to move the damper shaft, rotate the actuator approximately 5° in the direction which would open the damper.

11. Tighten the universal clamp to the shaft.

12. Rotate the actuator to apply pressure to the damper seals (b) and re-engage the anti-rotation strap (c).

13. Tighten all fasteners.

3. Engage the clamp to the actuator as close as possible to the determined location.

4. Lock the clamp to the actuator using the retainer clip.

5. Mount the spring return actuator to the shaft. Tighten the universal clamp, finger tight only.

6. Mount the anti-rotation strap at the base of the actuator. Do not tighten the screws.

7. Remove the screw from one end of the mounting bracket and pivot it away from the actuator.

8. Loosen the universal clamp and, making sure not to move the damper shaft, rotate the actuator approximately 5° in the direction which would open the damper.

9. Verify that the damper is still in its full fail-safe position.

10. Tighten the universal clamp to the shaft.

Short Shaft Mounting

Remounting the Stroke Limiter

1. Remove the stroke limiter by inserting a small screwdriver, like the one shown, and gently prying upward. This procedure takes very little force. See Figure 1.

2. While holding the back eye-let, unscrew the end-stop so that eye-let separates from the end-stop.

3. Flip the limiter over, so the teeth point the other direction. Replace the eye-let and end-stop.

4. Flip the actuator over to the opposite side (this reverses the spring return direction of the actuator). Replace the stroke limiter assembly by inserting the first two teeth as shown in the orange circle. Then press the stroke limiter into place by pushing downward on the adjustable stop.

5. Replace clamp and retaining clip.

The TTF actuators are provided with an adjustable stop to limit the rotation of the actuator. This function works in conjunction with the universal clamp or the optional position indicator. The adjustable stop is needed when rotation of less than 95° is required. The TTF actuator can be indefinitely stalled, in any position, without harming the actuator.

Using the Universal Clamp:

1. Loosen the end stop fastening screw using a #2 Phillips screwdriver.

2. Move the stop block so the bottom edge of the block lines up with the number corresponding to the desired degrees of rotation (example: 45 degrees of rotation = .5).

3. Lock the block in place with the fastening screw.

4. Check the actuator for proper rotation.

Using the IND-TF Position Indicator with Adjustable Stop:

Note: preferred method if short shaft mounting is used.

1. With the actuator in its fail-safe position, place the IND-TF Position Indicator so that it points to the 0 degree position.

2. Loosen the end stop fastening screw using a #2 Phillips screwdriver.

3. Move the stop block so the bottom edge of the block lines up with the number corresponding to the desired degrees of rotation (example: 45 degrees of rotation = .5).

4. Lock the block in place with the fastening screw.

5. Check the actuator for proper rotation.

Mechanical Angle of Rotation Limiting

Installation Instructions

Quick-Mount Visual Instructions for Mechanical Installation

TTF24-3 and TTF24-SR actuators have a direction of rotation switch on the cover labeled “CW-CCW”. Switch position indicates start point. For the TTF24-SR, with the switch in position “CW”, the actuator rotates clockwise with a decrease in voltage or current. With the switch in position “CCW”, the actuator rotates counterclockwise with a decrease in voltage or current.

The TTF24-3 and TTF24-SR actuators rotate clockwise when the switch is in the “CW” position and power is applied to wire #3. When power is applied to wire #4 the actuator rotates counter clockwise.

Rotating the direction of rotation switch to “CCW” reverses the control logic.

During checkout, the switch position can be temporarily reversed and the actuator will reverse its direction. This allows the technician a fast and easy way to check the actuator operation without having to switch wires or change settings on the controller. When the check-out is complete, make sure the

switch is placed back to its original position.

Direction of Rotation Switch

Initialization of the TTF24-SR

When power is applied, the internal microprocessor recognizes that the actuator is at its full fail-safe position and uses this position as the base for all of its position calculations. This procedure takes approximately 15 seconds. During this time you will see no response at the actuator. The microprocessor will retain the initialized zero during short power failures of up to 25 seconds. When power is applied during this period, the actuator will return to normal operation and proceed to the position corresponding to the input signal provided. For power failures over 25 seconds, the actuator will be at its fail-safe position and will go through the start up initialization again.

Motor Position Detection (TTF24-SR)

Brushless DC motors eliminate the need for potentiometers for positioning. Inside the motor are three “Hall Effect” sensors. These sensors detect the spinning rotor and send pulses to the microprocessor which counts the pulses and calculates the position to within 1/3 of a revolution of the motor.

Overload Protection

The TTF, on-off actuators are electronically protected against overload. The TTF, on-off actuator have an internal current limiter which maintains the current at a safe level which will not damage the actuator while providing adequate holding torque.

The TTF24, modulating, actuators (TTF24-SR, TTF24-3) are protected against overload by digital technology located in the ASIC. The ASIC circuitry constantly monitors the rotation of the brushless DC motor inside the actuator and stops the pulsing to the motor when it senses a stall condition. The motor remains energized and produces full rated torque during stall conditions. The actuator will try to move in the direction of the stall every 2 minutes, for a period of 32 minutes. After this, the actuator will try again every 2 hours.

Installation Instructions

The …-S model actuators are equipped with an adjustable auxiliary switch used to indicate damper position or to interface additional controls or equipment. Switching positions can be set over the full 0° to 95° rotation simply by setting a switch on the actuator.

1. Set desired switch position (Example 60%).

2. As the actuator rotates, the switch indicator moves from .6 (60%) toward 0 (0%).

TTF24-SR actuators have built-in brushless DC motors which provide better accuracy and longer service life. The TTF24-SR actuators are designed with a unique non-symmetrical deadband. The actuator follows an increasing or

decreasing control signal with a 80 mV resolution. If the signal changes in the opposite direction, the actuator will not respond until the control signal changes by 200 mV. This allows these actuators to track even the slightest deviation very accurately, yet allowing the actuator to “wait” for a much larger change in control signal due to control signal instability.

WARNING The wiring technician must be trained and experienced with electronic circuits. Disconnect power supply before attempting any wiring connections or changes. Make all connections in accordance with wiring diagrams and follow all applicable local and national codes. Provide disconnect and overload protection as required. Use copper, twisted pair, conductors only. If using electrical conduit, the attachment to the actuator must be made with flexible conduit.

Always read the controller manufacturer's installation literature carefully before making any connections. Follow

all instructions in this literature. If you have any questions, contact the controller manufacturer.

Transformer(s)

The TTF24 . . actuator requires a 24 VAC class 2 transformer and draws a maximum of 5 VA per actuator. The actuator enclosure cannot be opened in the field, there are no parts or components to be replaced or repaired.

– EMC directive: 89/336/EEC – Software class A: Mode of operation type 1 – Low voltage directive: 73/23/EEC

CAUTION: It is good practice to power electronic or digital controllers from a separate power transformer than that used for actuators or other end devices. The power supply design in our actuators and other end devices use half wave rectification. Some controllers use full wave rectification. When these two different types of power supplies are connected to the same power transformer and the DC commons are connected together, a short circuit is created across one of the diodes in the full wave power supply, damaging the controller. Only use a single power transformer to power the controller and actuator if you know the controller power supply uses half wave rectification.

Multiple Actuators, One Transformer

Multiple actuators may be powered from one transformer provided the following rules are followed:

1. The TOTAL current draw of the actuators (VA rating) is less than or equal to the rating of the transformer.

2. Polarity on the secondary of the transformer is strictly followed. This means that all No. 1 wires from all

actuators are connected to the common leg on the transformer and all No 2 wires from all actuators are connected to the hotleg. Mixing wire No. 1 & 2 on one leg

of the transformer will result in erratic operation or failure of the actuator and/or controls.

Multiple Actuators, Multiple Transformers

Multiple actuators positioned by the same control signal may be powered from multiple transformers provided the following rules are followed:

1. The transformers are properly sized.

2. All No. 1 wires from all actuators are tied together and tied to the negative leg of the control signal. See wiring diagram.

Wire Length for TTF… Actuators

Keep power wire runs below the lengths listed in the table in Figure A. If more than one actuator is powered from the same wire run, divide the allowable wire length by the number of actuators to determine the maximum run to any single actuator. Example for TTF24-SR:

3 actuators, 16 Ga wire 550 ft ÷ 3 Actuators = 183 ft. maximum wire run

Maximum Wire Length:

Wire Size Max. Feet. Wire Size Max. Feet

12 Ga 1300 Ft. 18 Ga 575 Ft. 14 Ga 1175 Ft. 20 Ga 300 Ft. 16 Ga 900 Ft. 22 Ga 150 Ft.

Figure A Wire Type and Wire Installation Tips

For most installations, 18 or 16 Ga. cable works well with the TTF24… actuators. Use code-approved wire nuts, terminal strips or solderless connectors where wires are joined. It is good practice to run control wires unspliced from the actuator to the controller. If splices are unavoidable, make sure the splice can be reached for possible maintenance. Tape and/or wire-tie the splice to reduce the possibility of the splice being inadvertently pulled apart.

The TTF24… proportional actuators have a digital circuit that is designed to ignore most unwanted input signals (pickup). In some situations the pickup may be severe enough to cause erratic running of the actuator. For example, a large inductive load (high voltage AC wires, motors, etc.) running near the power or control wiring may cause excessive pickup. To solve this problem, make one or more of the following changes:

1. Run the wire in metallic conduit.

2. Re-route the wiring away from the source of pickup.

3. Use shielded wire (Belden 8760 or equal). Ground the

shield to an earth ground. Do not connect it to the actuator common.

Brushless DC Motor Operation

The brushless DC motor spins by reversing the poles of stationary electromagnets housed inside rotating permanent magnets. The electromagnetic poles are switched by a microprocessor and a special ASIC (Application Specific Integrated Circuit). Unlike the conventional DC motor, there are no brushes to wear or commutators to foul.

Preliminary Steps

1. Actuators should be mounted indoors in dry, relatively clean environment free from corrosive fumes. If the actuator is to be mounted outdoors, a protective enclosure must be used to shield the actuator. (See Mechanical Accessories Section)

2. For new construction work, order dampers with extended shafts. Instruct the installing contractor to allow space for mounting and service of the actuator on the shaft.

3. For standard mounting, the damper shaft must extend at least 3 1/2" from the duct. If the shaft extends less than 3 1/2", the actuator may be mounted in its short shaft configuration.

Installation Instructions

Quick-Mount Visual Instructions

1. Rotate the damper to its failsafe position. If the shaft rotates counterclockwise, mount the “CCW” side of the actuator out. If it rotates clockwise, mount the actuator with the “CW” side out.

2. If the universal clamp is not on the correct side of the actuator, move it to the correct side.

3. Slide the actuator onto the shaft and tighten the nuts on the V-bolt with an 8 mm wrench to 6-8 ft-lb of torque.

4. Slide the anti-rotation strap under the actuator so that it engages the slot at the base of the actuator. Secure the strap to the duct work with #8 self-tapping screws.

Torque min. 180 in-lb for control of damper surfaces up to 45 sq ft.

Application

For on/off and floating point control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications.

The actuator is mounted directly to a damper shaft up to 1.05” in diameter by means of its universal clamp, self-centered default. A crankarm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft.

Operation

The actuator is not provided with and does not require any limit switches, but is electronically protected against overload. The anti-rotation strap supplied with the actuator will prevent lateral movement.

The TAMB series provides 95° of rotation and a visual indicator indicates position of the actuator. When reaching the damper or actuator end position, the actuator automatically stops. The gears can be manually disengaged with a button on the actuator cover.

The TAMB24-3… actuators use a sensorless brushless DC motor, which is controlled by an Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the actuator’s rotation and provides a digital rotation sensing (DRS) function to prevent damage to the actuator in a stall condition. Power consumption is reduced in holding mode.

Add on auxiliary switches or feedback potentiometers are easily fastened directly onto the actuator body for signaling and switching functions.

For all accessories, see pages 110 and 132.

Application

For on-off and floating point control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications.

The actuator is mounted directly to a damper shaft from 1/4” up to 5/8” in diameter by means of its standard universal clamp. Shafts up to 3/4” diameter can be accommodated by an accessory clamp.

Operation

The actuator is not provided with and does not require any limit switches, but is electronically protected against overload. The anti-rotation strap supplied with the actuator will prevent lateral movement.

The TLMB series provides 95° of rotation and a visual indicator which indicates position of the actuator. When reaching the damper or actuator end position, the actuator automatically stops. The gears can be disengaged with manual release on the actuator cover.

The TLMB24-3… actuators use a sensorless brushless DC motor, which is controlled by an Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the actuator’s rotation and provides a digital rotation sensing (DRS) function to prevent damage to the actuator in a stall condition. Power consumption is reduced in holding mode.

Add on auxiliary switches or feedback potentiometers are easily fastened directly onto the actuator body for signaling and switching functions.

For all accessories, see pages 110 and 132.

Installation and Operation

Non-Spring Return

General Information

If more torque is required than one TGMB can provide, TGMB24-SR may be installed on the same shaft.

Multiple Actuator Mounting

Preliminary Steps

1. Belimo actuators with NEMA 1 or NEMA 2 ratings should be mounted indoors in a dry, relatively clean environment free from corrosive fumes. If the actuator is mounted outdoors, a protective enclosure must be used to shield the actuator.

2. For new construction work, order dampers with extended shafts. Instruct the installing contractor to allow space for mounting the Belimo actuator on the shaft.

For replacement of existing gear train actuators, there are two

options:

A. From a performance standpoint, it is best to mount the

actuator directly onto the damper shaft.

B. If the damper shaft is not accessible, mount the non-

spring return actuator with a ZG-NMA or ZG-GMA crankarm kit, and a mounting bracket (ZG-100, ZG101, ZG-103, ZG-104)

Determining Torque Loading and Actuator Sizing

Damper torque loadings, used in selecting the correct size actuator, should be provided by the damper manufacturer. If this information is not available, the following general selection guidelines can be used.

Damper Type Torque Loading

Opposed blade, without edge seals, for non-tight close-off applications 3 in-lb/sq. ft.

Parallel blade, without edge seals, for non-tight close-off applications 4 in-lb/sq. ft. Opposed blade, with edge seals, for tight close-off applications 5 in-lb/sq. ft. Parallel blade, with edge seals, for tight close-off applications 7 in-lb/sq. ft.

The above torque loadings will work for most applications under 2 in. w.g. static pressure or 1000 FPM face velocity. For applications between this criteria and 3 in. w.g. or 2500 FPM, the torque loading should be increased by a multiplier of 1.5. If the application calls for higher criteria up to 4 in. w.g. or 3000 FPM, use a multiplier of 2.0.
