IMPORTANT: Electrical wiring for the PowerTrak™ should be at least 14 gauge, but all wiring should be

in accordance with National Electric Code or other local codes.

Physical Description/Drawing

Limit Switch Assembly

The limit switch assembly includes the limit switches, tensioning springs (20), guide rod (21), cotter pins

(15) and adjustment collars (17 and 18). These components work together to stop the motor when the

machine reaches the end of its travel. The auxiliary switches allow you to hook-up the equipment that

should run/not run when the curtains are closed, or all the way open. Refer to Figure 2A on Page 10.

Drive Assembly

The drive assembly includes the motor, bearings (6), coupling (12), screw and the load block. The

PowerTrak™ Vent Machine motor you have depends upon the speed of the machine you ordered. You

may have a 15 RPM, 30 RPM or 60 RPM motor. Refer to Figure 2A on Page 10.

Pulley Assembly

The pulley assembly is at the top of the machine. It consists of three pulleys which are spaced to allow the

cables to go out both sides of the machine for two curtain operation, or you can run both cables out of the

same side for one curtain operation.

NOTE: An optional chain and sprocket assembly is also available which can be used instead of the pulley

assembly.

Wiring Harness

The wiring harness includes all connectors and wiring to route the power through the limit switches and to

the motor. See wiring diagram on Pages 17-19 for detailed wiring instructions.

High voltage present inside the machine. If you need to reach inside the machine,

disconnect power to the machine first.

Dangerous rotating machinery. Keep hands, clothing, etc. clear when operating.

3. Installation

12 4801-0154 PowerTrak™ Curtain/Vent Actuator

3. Install one 3/8" lag bolt (39) through the wall of the building at the desired location.

NOTE: Place this bolt at 5-1/2" from the desired height, so that the machine top lines up with that

height. Refer to Figure 3B.

NOTE: Distance between holes depends upon length of the machine.

For example: If you have a six foot machine, the holes should be placed 78-3/8" apart.

Figure 3B

4. Hang the PowerTrak™ on the lag bolt (39) through the slot near the top center of the machine (32).

Refer to Figure 3C.

NOTE: This bolt is only for hanging the PowerTrak™ during installation. Do not attempt to operate

the machine until it is fully secured. To secure the PowerTrak™, use the remaining six 3/8"

lag bolts (39) provided. Drill the bolts through the four holes (33) in the back wall of the

PowerTrak™ and the two flange holes (34) at the top on each side of the hanging lag bolt.

3. Installation

4801-0154 PowerTrak™ Curtain/Vent Actuator 13

5. Install the corner brackets, hand winches, thru-wall brackets, etc. as shown on the charts in the

“Cabling Options”. Care should be taken when installing the brackets, pulleys, etc. to make sure that

cabling will not interfere with the normal operation of doors, windows, etc.

IMPORTANT: It is necessary to use only needle bearing pulleys on any “live” pulley (one that turns

every time the curtain moves) as this will extend the life of the machine and cables.

6. Run the cable (36) through the pulleys (35) and brackets as per the selected chart.

Figure 3D

7. When hooking-up the cables (36), leave the load nut (4) near the closed position (The PowerTrak™

should have been shipped in this position). This guarantees that the manual winches will have

enough cable (36) to allow manual operation of the curtains.

8. Run the ends of cables (36) through the pulley assembly to the load block. On the load block there

will be four holes on the top surface. Run the cables (36) down the holes toward the center of the

block, loop around and come up through the holes toward the outside of the block. Tighten the set

screws on the face of the load block to lock down the cables (36). Pull the cable (36) through the

pulleys as shown below in Figure 3E on Page 14.

NOTE: The cables should come out of the pulleys at the right angle (90°) with the cabinet. This is to

make sure that there is even wear on the load block. Changing the exit angle of the cable

(36) changes the force seen on that side of the load block. Refer to Figure 3F on Page 14.

This above figure shows a 1:1 ratio. Thus 1"

of machine movement gives 1" of curtain

movement.

This above figure shows a 1:2 ratio. Thus 1"

of machine movement gives 2" of curtain

movement.

9. If for any reason it is necessary to mount the PowerTrak™ horizontally, punch the “Knockouts” and

run the cables straight through the top of the machine. It is very important to loop the cable around

a needle bearing pulley as shown in Figure 3H on Page 15 to make sure weight is evenly distributed

on the load block. This pulley also acts as a spacer to keep the cables straight.

When one PowerTrak™ is used to

pull two curtains, loop the cables

as shown in above figure.

When one PowerTrak™ only pulls

the curtains, to the right, loop the

cables through the pulleys as shown

in above figure.

When one PowerTrak™ only pulls the

curtain to the left side of the machine,

loop the cables through the pulleys as

shown in above figure.

10. Hook-up electrical wiring as shown in the wiring diagrams. Refer to on Pages 17-19.

NOTE: All wiring must comply with all National and Local Electric Codes.

11. With the controller in manual mode, close the machine fully. Then take up the slack on the cabling

with the manual winch.

NOTE: With the PowerTrak™, you have the ability to adjust the lower limit switch set point, however,

the factory setting should be sufficient for most applications.

12. Next, open the curtains with the manual controls. When the curtain reaches the bottom of the

opening, or whichever point you choose, stop the curtain motion and set the high adjustment collar

(near the top of the machine) on limit switch guide rod to this point. Use an allen wrench for loosening

and tightening the set screw (3) on the collar.

13. Attach a small cable clamp (37) to the cable (36) near the hand winch (40) as a reminder not to wind

the cables past this point.

4. Maintenance

The PowerTrak™ is designed to operate with a minimum of maintenance. However, the following steps

must be performed on a regular basis to ensure peak performance over the unit’s lifetime.

1. The most crucial maintenance item is lubrication. We recommend using Valvoline Val-Plex EP™

wheel bearing grease for this purpose. The full length of the screw, and the “V shaped” tracks on the

sides of the cabinet (where the load block runs) should be wiped from top to bottom with grease.

There are five grease fittings provided on the PowerTrak™ one on the load nut (60 RPM only), one

on the thrust bearing (just above the spider coupling), and three on the pulleys in the top. Each

bearing should receive two pumps with a grease gun (or until grease appears on both sides of the

bearing) at least every 3 months.

2. To grease the screw, apply the grease directly to the threads. Then use the manual setting on the

controller to move the load nut from one end of the screw to the other while applying grease. This is

to make sure that the full range of the load nut is well lubricated.

IMPORTANT: Do not use WD-40™ or other similar products for lubrication or cleaning of this

machine.

3. Products of this nature will remove the grease from the unit, causing excessive wear on load bearing

surfaces and increasing the possibility of binding.

4. It is also important to keep the debris out of the enclosure. The door on the unit should be sufficient,

but it is still recommended that you do a visual inspection and clean out any wasp nests, etc. It is

acceptable to blow debris out of the unit with pressurized air, but never spray the internals with water

unless power is completely disconnected from the unit.

5. Inspect cables periodically, especially at the onset of cold weather. Damaged cables can break, and

the risk is higher in colder temperature. Replace any badly frayed or excessively worn cables.
