A Unique Concept in Roll-up Door Automation
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 fi ttings, not needed
for automated operation. If fi tted, leave the centre lock un-locked.
WARNING!
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
on page 11
• 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 fi x labels warning against entrapment in a prominent
place or near any fi xed controls.
After installation, ensure that the mechanism is properly adjusted and
reverses when closing upon an obstacle, 40mm high, placed on the
fl oor.
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.
Step 1
Inserting the chains into the Sprocket Covers, left and right
Insert the fi rst 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.
Step 2
Fixing the Chain Anchor to the fl oor, left and right
Starting on the left side, mark out the drilling dimensions as in Figure 2.
Using a Ø8 mm masonry bit, drill each hole as indicated to a depth of at
least 65 mm, and fi t 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 fl oor; 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 fl ush. Apply a lick of grease to the bolt threads before fi tting.

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.
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, fi rst and fourth from
the right of the Controller. See 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). 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).
Cut the Shaft at that mark and de-burr the sharp edge with a fi le. 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 3
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.
Refer to 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 fi tted, 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.
Drill through the upper-right
mounting bush with a Ø6 mm
bit.
Reach under the bottom rail
and push an M6 Cup Square
Bolt through the hole and the
mounting bush, and fi t 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. Refi t the unit using
four M6 Cup Square Bolts and M6 Nuts, tightening them with a 10 mm
socket nut-driver until the heads are fl ush 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.
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, fi t an M6 Cup Square Bolt and nut, fi nger-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 fl ush on the outside.

As in Figure 3, engage the pin at the end of the chain in the ‘V’ of the Chain
Anchor. Ensuring that the chain is between the wall and the sprocket in the
cover, place the Chain Anchor over the screw plugs and fi t 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.
