Digidoor Paratrak - Garage Door Opener Installation Manual

Features

The Paratrak drives the door symmetrically by means of chains and sprockets, applying the force symmetrically to both ends of the bottom rail, ensuring smooth and even operation.

Intended Use

The Paratrak is intended for the automation of the Digi Roll-up Door, and may be adapted to other makes of roll-up doors by means of Adapter Kits. Typically, a roll-up door weighs about 30 kg.

The width of a roll-up door may vary from 2,44 m to 3 m, and the height from 2,135 m to 3 m.

Longer Drive Shafts and Chain Kits are available for wider and/or higher doors.

If needed, (e.g. to avoid a tow-bar on a vehicle in a short garage) the Paratrak may be mounted off-centre. This is possible, and the longer Drive Shafts are required.

Paratrak Installation Instructions on Digi Roll-up Doors

Preparation

Prior to automating the roll-up door, inspect the door with a view to ensuring satisfactory manual operation; it is a mistake to imagine that automation will overcome the faults of a mal-functioning door.

The operator will interpret excessive resistance to door movement, due to poor alignment, balance, snagging or excessive wear and tear of working surfaces as an obstacle thereby preventing reliable movement of the door. Eliminate all hindrances to free and smooth door operation.

Check that the side-guides are free of grease, dirt and dents; and are secure, vertical and straight.

Check that the triangular support brackets are secure and level. The springs inside the door roll should have a light coating of grease.

The door should operate smoothly and easily using one hand, and remain stationary when left at any point of travel. Adjust the spring force if necessary (refer to the door installation instructions).

Remove or disable any unnecessary equipment or fittings, not needed for automated operation. If fitted, leave the centre lock un-locked.

Important Safety Instructions

Follow all instructions carefully, as incorrect installation could lead to severe injury. It is important for the safety of persons to follow all instructions. Save these instructions for future reference.

• Do not allow children to play with door controls
• Automated doors should only be operated whilst in full view
• Take care when operating the manual release since an open door may fall rapidly due to weak or broken springs, or mal-adjustment
• Frequently examine the installation for signs of wear or damage, in particular, that tracks and mountings are secure, and that the balance of the springs is correctly adjusted
• For use of the manual release, refer to the section Manual Operation
• During maintenance or adjustment, disconnect the mains supply
• This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

Permanently fix labels warning against entrapment in a prominent place or near any fixed controls.
After installation, ensure that the mechanism is properly adjusted and reverses when closing upon an obstacle, 40mm high, placed on the floor.
The drive must not be used on a roll-up door incorporating a wicket door (unless the roll-up door cannot be operated if the wicket door is closed).
After installation, ensure that parts of the door do not extend over public foot paths or roads.

INSTALLATION

It is assumed that the proper condition and balance of the door has been achieved.

A video is available on our website to assist you with this installation.

Step 1: Inserting the chains into the Sprocket Covers, left and right

Insert the first link (the one without the anchor pin) of one of the chain bundles into the opening of the shorter side of a Sprocket Cover assembly. Push the chain through, link-by-link, until it emerges at the other side. Pull the chain about halfway through the assembly. Repeat for the other chain bundle and Sprocket Cover assembly. See Figure 1.

Figure 1.

Step 2: Fixing the Chain Anchor to the floor, left and right

Starting on the left side, mark out the drilling dimensions as in Figure 2.

Figure 2 Left Side. Mirror for the Right side.

Using a Ø8 mm masonry bit, drill each hole as indicated to a depth of at least 65 mm, and fit two Ø8 x63 Screw Plugs. Please refer to the following tips.
Note: the box has a drilling template for ease of use.

TIPS

1. Accuracy is important! Before drilling, extend the centre-lines well beyond the hole-positions.
2. Start each hole with the drill set to normal (no hammer) and, while focusing on accuracy, drill initially to a depth of about 5mm before changing the drill to hammer.
3. To avoid snapping screws inserted in the floor; after drilling each hole, leave the mounds of dust. Insert the tips of the screw-plugs part-way into the holes, and then brush away the mounds of dust. Drive the plugs in flush. Apply a lick of grease to the bolt threads before fitting.

As in Figure 3, engage the pin at the end of the chain in the 'V' of the Chain Anchor.

Figure 3

Ensuring that the chain is between the wall and the sprocket in the cover, place the Chain Anchor over the screw plugs and fit two Ø6 Coach Bolts with Body Washers. At this stage, leave the bolts loose enough to allow the Chain Anchor to move ('Float') freely. Repeat for the right side.

Step 3: Securing the Chain to the triangular support bracket

Again, starting on the left side, mark the drilling position on the upper fl ange of the triangular support bracket as in Figure 4. Centre-punch and drill a Ø4.5 mm hole.

Figure 4

Refer to Figure 5.

Figure 5

Near the top end of the chain, choose a chain link such that, when an M4 Socket Head Cap Screw is pushed through that link and through the Ø4.5 mm hole in the triangular support bracket, a washer and an M4 Nylok Nut can be fitted, leaving suffi cient thread on the bolt so that the chain may be tensioned. For now, take up the slack. Repeat for the right side.

Step 4: Mounting the Paratrak and the Battery Box

With the foot of the door opened to waist height, measure and mark the horizontal mid-point of the door just above the bottom rail. Position the Paratrak unit with its output stage centred on the mid-point of the door, and its underside touching the aluminium bottom rail.

Figure 6

Drill through the upper-right mounting bush with a Ø6 mm bit.
Reach under the bottom rail and push an M6 Cup Square Figure 6 Bolt through the hole and the mounting bush, and fit an M6 nut, fi nger-tight. Now, with the Ø6 mm bit, drill through the remaining three mounting bushes. Remove the unit from the door and enlarge all the holes with a Ø7 mm bit. Refit the unit using four M6 Cup Square Bolts and M6 Nuts, tightening them with a 10 mm socket nut-driver until the heads are flush on the outside.

Step 5: Battery Box

Hold the Battery Box (without batteries) against the door to the left of the Paratrak with its feet standing on the bottom rail, with a 30 mm gap between the two.

Figure 7

In this position and on the right of the box, drill through the mounting bush that best suits the corrugation of the door with a Ø6 mm bit. As above, fit an M6 Cup Square Bolt and nut, finger-tight. Drill through the corresponding mounting bush on the left. Remove the Box and enlarge the holes with a Ø7 mm bit. Secure the Box with two M6 Cup Square Bolts and nuts, tightening them with a 10 mm socket nut-driver until the heads are flush on the outside.

Step 6: Connecting the Cables

Flex the side clips and remove the Light Cover from the front of the Battery Box. Set the cover aside until later.

Place the two batteries in the Battery Box with the terminals of each near the middle.

Figure 8

As in Figure 8, connect the Black battery wire to the left Black terminal, and the Red battery wire to the right Red terminal. Leave the 3-Pin plug from the batteries un-plugged at this stage. Connect the White Jumper wire from the left Red terminal to the right Black terminal. Insert the matching plugs from the Paratrak into the sockets, first and fourth from the right of the Controller. See Figure 9.

Figure 9

At this stage, check that the door is neutrally balanced. If necessary, adjust the spring force to balance the door.

Step 7: Cutting the Shafts to length

Starting on the left side, move the Sprocket Cover assembly to the same level as the bottom rail. Note the size of the gap between the Sprocket Cover and the side guide (see Figure 10).

Figure 10

Insert the formed end of a Shaft into the hub of the sprocket inside the Sprocket Cover Assembly and, while maintaining the gap, hold the Shaft horizontally so that it overlaps the hub of the Paratrak, and mark the Shaft opposite the centre of the nearest hub screw (see Figure 11).

Figure 11

Cut the Shaft at that mark and de-burr the sharp edge with a file. Slide two Bearing Brackets onto the shaft, clip them into the bottom rail (as in Figure 12) and push the end of the shaft into the Output Shaft.

Figure 12

Step 8: Securing the Shaft to the Motor

With the door open to slightly above waist level (for a comfortable working height), check that the foot of the door is level.

Move the Manual Over-ride Lever anti-clockwise and turn the Output Shaft by hand until the holes are horizontal, as in Figure 13.

Figure 13

Re-engage the motor by moving the Manual Over-ride Lever clockwise to lock the Output Shaft in place.

Check that the gap between the Sprocket Cover and the side guide is correct (Figure 10). Using a sharp Ø4 mm bit, carefully drill through the hole in the Output Shaft with attention being paid to keeping central, level and square. Push an M4x20 Socket Head Cap Screw through the hole just drilled.

Repeat 'Cutting' and 'Securing the Shaft' for the right side (Steps 7 and 8), remembering to slide the two Bearing Brackets onto the other Shaft. Release the motor by means of the Manual Over-ride Lever, lift the door until the tips of the M4 screws come into view and fit M4 Nylok Nuts. Lower the door until the Heads of the M4 screws come into view. Tighten the M4 screws and nuts with a 7 mm spanner and a 3 mm Allen key.

Step 9: Securing the Bearing Brackets

(For a Digi-Roll-up: If fitted, remove the red Foot Stops from the bottom Rail.)

On the left side, position the left edge of the Bearing Bracket flush with the end of the aluminium Bottom Rail. Using a Ø3.5 mm bit, drill through the mounting bushes in the Bearing Bracket and fit two #8x25 mm Self Tapping Screws. Likewise, mount the next Bearing Bracket 600 mm to the right of the first. Repeat the above for mounting the Bearing Brackets on the right side. Snip a corner off of the grease sachet and apply grease to the shafts where they are visible in each bracket, as well as the underside.

Tensioning the Chains
Release the motor by means of the Manual Over-ride Lever and, by hand, close the door fully. Now tighten the Ø6 mm Coach Bolts in the Chain Anchors, left and right.
Using a 3 mm Allen Key and a 7 mm spanner, tighten the M4 Nylok Nut above the triangular support bracket, to tension the chains so that no slack is evident and both chains feels firm. Refer to Figure 5.

Step 10: Mounting the Power Pack and Junction Box

Remove the dust-cover from the Junction Box. Depending on the position of the nearest mains 3-pin power socket, choose a front or side wall. On that wall, using the #4 screws and Ø5.5 mm plugs supplied, mount the Junction Box as in Figure 14, 1.1 m from the floor and 100 mm from the side guide of the door.
Take care to avoid damaging the wires in the Junction Box.

Figure 14

Plug the Power Pack into the 3-Pin Mains Socket; do not switch on yet. Use the twin-fl ex cable to connect the Power Pack to the Junction Box as in Figure 15, making use of the Yellow and Blue terminals, marked 'AC 24V'.

Figure 15
( Note: depending on the position of the power point, a longer length of twin-fl ex may be required). Secure the cable to the wall by means of cablesaddles. Fit the dust-cover to the Junction Box. Plug the short end of the curly cord into the Junction Box.

As in Figure 16, attach the beginning of the straight portion of the curly cord to the tip of the nearest bearing bracket with a cable-tie, then at the diagonal attachment point.

Figure 16

Plug the free end of the curly cord into the socket third from the right of the Controller (Figure 9). Secure the cord to the next bearing bracket with a cable-tie. Finally, fold up any slack cable and secure it with a cable-tie.
Trim the free ends of the cable-ties.

Step 11: Set-up

Switch on the Power Pack at the 3-Pin Mains Socket.

Referring to Figure 9, plug the 3-Pin plug from the batteries into the socket, second from the right on the Controller. The lights will flash and the beeper will sound, and the LED on the Controller will flash orange. (If the LED shows green, a 'Reset' is required; see Reset).

• Ensure that the Limit Slide is in the upper-most position. Refer to Figure 17
  
  Figure 17
• Move the Manual Over-ride Lever fully anti-clockwise
• Press the button on the Controller and the LED will show red
• By hand, move the door to the closed position against the floor
• Move the Manual Over-ride Lever fully clockwise
• Depress the Limit Slide Button and move the Limit Slide slowly downwards, until the LED on the Controller changes from red to green. Release the Limit Slide Button.

Keep clear during this phase.

Press the button on the Controller (see Figure 9). The Paratrak will slowly open the door in 'seek' mode until the fully open position is reached. The Paratrack will then close, stopping on the floor.
The Controller will beep twice and the LED will double-flash orange.

Step 12: Adding the eKey Remote

Press the button on the Controller and the LED will flash orange. Within 30 seconds, press the chosen button on the eKey Remote, causing the LED to turn off. Press the same button on the eKey Remote again and the LED will flash and the Beeper will sound four times. The eKey Remote is ready to use.
Note: For security reasons, adding remotes requires the door to be fully closed.

For additional eKey Remotes, repeat Step 12.

Reset.
If, for any reason, the Set-up procedure above needs to be repeated, first reset as follows:
From the Controller, un-plug the Telecom plug (Curly cord) and the Battery plug. Push and hold the button on the Controller while inserting the Battery plug. The Lights will flash and the Beeper will sound and the LED will flash orange. Continue Set-up (Step 11).

Step 13: Adjusting Obstacle Sensing

(For safety reasons, perform this check twice a year.) Referring to Figure 9, set the 'FORCE' adjuster mid-way. Using the eKey Remote, open the door. Start the door closing and, while standing to the left or right of the Paratrak, obstruct the door by hand. The door should sense the obstruction and reverse. If the force seems too high or low, make a slight change on the 'FORCE' adjuster (clock-wise for more), and test again.

ADDITIONAL INFORMATION

Erasing all eKey Remotes

Note: This procedure will erase all the eKey Remotes that have been added to the Paratrak. Ensure that all the relevant eKey Remotes are available, to re-add them after erasing. Referring to Figure 9, press and hold the button on the Controller. After ten seconds the LED will flash and the Beeper will sound four times. This indicates that all eKey Remotes have been cleared from memory.

Fitting a Key Release

A Key Release is required where there is no side door; the garage door providing the only access.

Refer to Figure 18.

Figure 18

In the second externally recessed corrugation above the Paratrak, mark a point 250 mm to the left of the Manual Over-ride Lever, and 150 mm above. Drill and mount the Key Release at this mark.

Measure the distance from the Key Release to the end of the Manual Over-ride Lever in the horizontal position. Cut the cable 150 mm longer than this distance. Insert the Key Release into the body and lock it. Loop the cable around the end of the Manual Over-ride Lever and secure it with an electrical screw clamp.

Manual Operation

To release the door from the Paratrak unit for manual operation, move the yellow lever at the right end of the unit, from its horizontal position in an anti-clockwise direction until it touches the body.

The door may now be moved by hand. To re-engage the drive, return the yellow lever to the horizontal position in a clockwise direction. Note that the door may be re-engaged in any position, and, if not closed, the next operation will cause the door to close slowly until the floor is reached.

Fitting Safety Beams

Choose and mark a suitable mounting height on both sides of the gate or doorway, low enough to protect toddlers and pets, but not lower than the under-side of most motor vehicles. Mount the Safety Beam units (Transmitter and Receiver) opposing one another, and at the chosen height. Note: Do not screw or rivet through the side tracks. This will interfere with the free movement of the curtain.

Wiring

(Refer to Figure 15)
In the Junction Box (dust cover removed), use the White terminal to supply positive(+) voltage to both beam units, and the black terminal to make the negative (-) connection to both beam units. If a Digitronic Safety Beam set is used, in the receiver unit, connect a short wire from negative (-) to 'COM'. Lastly, connect the Red terminal to the beam normally closed (N.C.) terminal on the beam Receiver unit.

Set-up

Referring to Figure 9, enable the Safety Beam by removing the link below the Telecom plug. The Safety Beam will not function if this is not done. Interrupting the beam during closing will cause the Paratrak to stop and reverse, but will be ignored during opening.

Enabling Auto-close

It is strongly advised that Safety Beams are fitted before making use of Auto-close.

Referring to Figure 9, remove the Auto-close Link to the right of the 3-way screw terminals. For convenience, store the Link on a single pin. The Auto-close timer will start after the door has stopped opening; after ten seconds the beeper will sound and the lights will flash for a further ten seconds before the door starts to close. Interrupting the safety beam will reset the timer, and the timer will not start while the beam is interrupted.

Fitting a Wall Console

Fix the Wall Console to the wall, in a convenient position (usually next to the side door) at a height of at least 1,5 m, within sight of the automated door, but clear of moving parts. To add the Wall Console to the Paratrak, close the door and un-clip the cover from the Battery Box. As in 'Adding an eKey Remote', press the button on the Controller and the LED will flash. Within 30 seconds, press the large button on the Wall Console, causing the LED on the Controller to turn off. Press the same button on the Wall Console and the LED will flash and the Beeper will sound four times. The Wall Console is ready for use. The large button will control the Paratrak (Open, Close and Stop). The button with the light symbol turns the Paratrak lighting on and off. (Note that this lighting will still go off after three minutes). Normal operation of the Paratrak is locked and un-locked by means of the button with the key symbol. The LED on the Controller changes from green to red when locked.

Fitting an Additional Receiver

An additional receiver may be connected by means of the terminals shown in figure 8. These are:
'-'(0V), '+'(24V) and '' (Operate, N.O. contact, active low signal). This receiver should not exceed 50mA. The range of this receiver may be degraded; if so, increase the mounting distance to at least 1 metre from the Controller.

Status Indications

The single L.E.D. on the controller indicates the status of the Paratrak as follows:

• Green (solid) - Ready, Mains is on
• Green (flashing) - Ready, Mains is off - battery voltage good
• Red (flashing) - Battery low – door cannot operate – restore mains to charge
• Red (solid) - Door locked by means of the wall console – will beep once when operation is attempted – unlock using the wall console
• Orange (flashing) - Reset – Programming mode – see Step 11.

Note: To save power, the Status L.E.D turns off when the Courtesy Light times out.
