Damper Actuator Sizing

Correct sizing of the actuator is necessary for proper control of d ampers. The area of damper that can be controlled by a given actuator is dependent upon the type of damper, the quality of the damper, the pressure dr op across the damper in the clo sed position, and the velocity of the air flow through the damper . To obtain actual damper torque requirements, contact the damper manuf acturer.

Damper Shaft Sizing

Use the “Long Damper Shaft ” mounting instructions if the damper shaft is at least 3-1/2" (90 mm) long.

Use the “Short Damper Shaft” mounting instructions if the damper shaft is shorter than 3-1/2" (90 mm) or the area around the dam per shaft is too narrow to allow stan dard mounting, as described in the “Short Damper Shaft” mounting section.

Changing Direction of Rotation

The MS40-7043, MS4X-7074, and MS4X-7153 actuators are equipped with a switch to control the direction of rotation. The switch can be set to "L” (left) or “R” (right) rotation. An actuator set to “L” will have a clockwise rotation when viewed from the left side. When viewed from the right side the rotation will be cou nterclockwise. Refer to Figure-3.

Caution:

moves the actuator against the -5° positive stop. Example: Viewing the actuator from the left side with th e swit ch set to “R” and an increasing signal. The actuator wil l at tempt to rotate beyond th e -5° st op and wil l stall.

These are spring return actuators. It is possi ble to switch to a directi on that

(MS40-7043 Series)

The MS40-7043 actuat or i s de signed for u se wi th j ackshaf ts up to 3/4" (19 mm ) in diamete r. In most applicat ions, the MS40-7043 actuator may be mounted in the same manner as a standard damper shaft application. If the jackshaft diameter is larger than 5/8" (16 mm) in diameter, the opti onal AM-710 universal cl am p mu st be used.

(MS4X-7153 and MS4X-70 73 Series)

The MS4X-7153 and MS4X-7073 ac tua tors a re desi gned for use with jac kshaf ts up to 1. 05" (27 mm) in diameter. In most appl ications, the act uator may be mounted in the same manner as a standard damper sh aft ap plica tion. I f the jac kshaft diamet er is l arger t han 3/ 4" (19 mm) in diameter, the optional AM-687 universal clamp must be used.

Multiple Actuator Mounting (MS4X-7153 only)

If more torque is required than one actuat or can provide, a second actuator may be mounted to the jackshaft or standard damper shaft, usi ng the AM-673 multipl e mounting brac ket. See Figure-4.

Caution:

MX41-707X, 715X - Do not attempt to use th e manual override with actuat ors

mounted in tandem. Damage to the gear train may occur.

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

• The total current draw of t he actuat ors (VA rati ng) is l ess than , or equal to, th e rating of

the transform er.

• Polarity on the secondary of the transformer is strictly followed.

– All Black wires f rom all actuators are connected to the common lead on the

transformer.

– All Red wires from all actuators are connect ed to th e hot l ead.

Caution:

Mixing the Black and Red wires on one l ead of t he transformer m ay result in

erratic operation or failure of the actuator and/or contro ls.

Multiple actuators positioned by the same control signa l may be powered from multiple transformer s provided the following r ules are followed:

• The transformers are properly sized.

• All Black wires from all actuators are tied together and tied to the negative lead of the

control signal.

Rotation Limitation Rotation Limitation for MS40-7043 Series

The Stop Block is used in conj unction with the tab on the univer sal clamp or the AM-709 position indicator. In order to func tion properly, the clamp or indicator must be mount ed correctly.

The Stop Block contr ols the rotational outp ut of the MS40-7043 and MF40-7043-501 actuators. It is used in applicat ions where a damper has a desi gned rotation th at is less than 90°, for exampl e with a 45° or 60° rotati ng damper. It can also be us ed to provide a m inimum damper positio n which is easily set, or changed, without removing the actuator from the damper.

1. Determine the amount of damper rotation required. The actuator stop block provides limited rotation from 40° to 95°.

2. Lo osen the screw securing the st op block to the actuator .

Note:

The actuator is shipped with the Stop Block mounted to the “L” side. If the damper application re quires the “R” si de face th e instal ler , simply remove the St op Block and sc rew and move it to the new location.

3. Slide the stop block into position, so that its edge lines up with the degree gradua tion on the actuator face which corresponds with the required rotation. See Figur e-5.

4. Sec ure the stop block in place .

5. Te st the damper rotation by applying power and the required control signal. Re-adjust if necessary.

Rotation Limitation for MS4X-7153 and MS4X-7073 Series

The AM-689 rotat ion lim iter is used in c onj uncti on with the t ab on t he univ ersal c lamp or t he AM-686 position indicator which comes with the AM-689. In order to function properly, the clamp or indicator must be mounted correc tl y.

The AM-689 rotation limiter controls the rotational output of the MS4X-7153, MS4X-7153502, MS4X-707 3, and MS4X- 707 3-502 act uator s. It is u sed in appl icat ions wher e a damper has a designed rot atio n that i s less t han 90°, fo r exa mple wit h a 45° or 60° rotatin g damper . It can also be used to provide a minimum damper position which is easily set, or ch anged, without removing the actuator from the damper.

1. Determine the am ount of damper rotat ion req uired .

2. Lo cate the AM-689 rotation limi ter on the actuator so that its edge lines up with the degree graduati on on the actuator face which corresponds with the required rotation. See Figure-6.

3. Find the appropriate cro ss-hair locatio n through the slot of the rotation limiter. This is the mounting loca ti on for the retaining screw.

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

5. Pos ition the rotatio n limiter b ack to the desired position , makin g sure the locatin g “teeth” on the rotation li m it er are engaged into the loca ti ng holes on the actuator.

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

7. Te st the damper rotation by ap plyin g power and the required co ntrol signal. Re-adjust if necessary.

Minimum Damper Positionin g

Note:

When using the AM-689 rotation limiter with an MS4X-7073 or MS4X-7153 actuator to provide a min imum dampe r posi tion, the sh ort sh aft mounti ng proce dure must be used t o mount the actuator .

Caution:

• The AM-689 rotation limiter should not be used with an MS4X-7073 or MS4X-7153

actuator to provide a minimum damper position in outdoor air damper app li cations. The rotation limi ter prevents the damper from reaching the full-cl osed position. This may cause coils to freeze or may cause other system problems to occur.

1. Position the damper to its minimum position by providing the appropriate control signal to the MS4X-70 73 or MS4X-7153.

2. Place the position indicator onto the actuator spline i n the approxim ate position shown in Figure-7. Fasten it with the retaining clip.

3. Place th e AM-689 r ot ation limi ter on the ac tuator s o that it either make s conta ct wit h, or is as close as possi ble to, the edge of the indicat or. See Figure-8.

4. Make sure t hat the loc ating teeth a re e ngaged in to the l ocati ng h oles on the act uat or. If all of the mounting te eth do not align with the holes, the mounting location of the indicator to the spli ne m ay have to be moved. The rotation l imiter would then be remounted to get the best position match of both parts.

5. Find the cross- hair location thr ough the slot of the rotati on limiter. Th is is the mounting location for th e retaining scre w .

6. Pierce through the label material to allow easy fastening of the retaining scre w.

7. Fasten the rotation limiter to the actuator using the self tapping screw provided.

CHECKOUT

After the entire system has been installed and the actuator has been powered up, the following check can be ma de for prope r system oper ation. Check for correct operation o f the damper while actua tor is being stroked.

1. Apply power to the actuator. Actuator and damper should be driven to their powered position as determined by the control signal.

2. On the MS4X-7XXX-50X models, check for correct auxiliary swit ch operation.

3. Break power to the actuator. Actuator and damper should return to the spring return position.

Note:

Check that the transformer(s) are sized properly.

• If a common transform er i s used with multiple actuators, make sure that polari ty is

observed on the secondary. This means connecting all Black wires to one leg of t he transformer and all Red wires to the other leg of the transformer.

• If multiple transformer s are used with one control signal, make sure all Black wires are

tied togethe r and tied to control signal negative (-).

• Controllers and actuators must have separate 24 Vac power sources.

Go, No Go Test 1. Turn 24 Vac power to actuator off.

2. Disconnect and temporarily insulate the yell ow/black input wire.

3. Wi th “L” side of the actuator fa cing the installer, set the L/R switch to “R.”

4. Tu rn actuator power back on.

5. Switch the L/R switch to the “L” posit ion.

6. Th e actuator should drive to the full counterclockwise position.

THEORY OF OPERATION

The actuators are mounted directly onto a damper shaft using a universal V-clamp. When the actuator is powered and a Vdc or mAdc control signal is applied to the actuator by the controller, the actuator rotates to a position determined by the control signal. At the same time the spring ret urn me chanism i s tensed. When power i s removed f rom the actu ato r, the spring returns the actuator to its normal position. The act uators provide true mechanical spring return operation for reliabl e, positive close -off on air tight dampers.

The MS40-704X-501 models are provided with one built-in auxiliary switch. The SPDT switch is provided for interfacing or signaling, for example, fan startup. The switching function is adjustable between 0° and 95° rotat ion (0 to 1 scale).

All MX4X-7XX3-XXX series ac tuat ors use a brushless DC motor which is controlled by a microprocess or. The m icropro cessor supp lies i ntelligence to p rovide a constant rotatio n rate and to know the ac tuator’ s exact normal position. The micro processor moni tors and c ontrols the brushles s DC motor’s r otation and pr ovides a digital sens ing function to prevent d amage to the actuator in a sta ll condition. The actuat or may be stalled anywhere in its normal rotation without the need for mechanica l end swi tches.

The MS4X-707X-502 and MS4X-715X-502 models are provided with two built-in auxiliary switches. The SPDT switches are provided for interfacing or signali ng, for example, fan startup. The switching function is adj ustable on one switch between 25° and 95° rotation, and the other switch is fixed to operation at 5° rotation.

All MS4X-7XX3 and MS4X-7XX3-5XX actuators provide a 2 to 10 Vdc feedback signal correspondi ng to the actua tor posi tion as det ermined by the control si gnal. MS 40-7043- MP and MS40-7043-MP5 model s provide a 20 Vdc, 25 mA power supply used to power TAC System 8000 control lers in lieu of position feedback.

The MS41-707X-XXX an d MS41- 715X- XXX actu ators are equi pp ed with a man ual ov errid e mechanism. This allows t he actuator to be manual ly posit ioned at an y point bet ween -5° and 85° rotation. This mechani sm is acc essibl e o n both sides of the ac tua tor an d ca n be used t o ensure tight close-offs for valves and dampers. The manual override should not be used while a unit is powered or on units that are mounted in tandem.
