Action Order.

Tools requiredto set-up the dome:

1. Make sure you have all dome's parts and suitable tools.

2. Prepare the place for shutter assembling. You will need a flat place, approx. 4.0x3.0m.

1. Read this manual understandingly.2. Check if you have all upgrade components.3. Disassemble old shutter drive and dismount the

engine and the reductor.4. Disassemble rods rollers.5. Unscrew limit switches plate.6. Take off the shutter.7. Take off aluminum guide rails.8. Fix new guide rails.9. Put shutter onto the dome.10. Fix front and rear shutter limiters.11. At the dome's top - cut out a hole for cog-wheel.12. Screw on shutter drive main holder to the dome.13. Assembly shutter motor module.14. Fix motor module with cog-wheel to shutter main

holder.15. Screw on shutter securing holders.16. Adjust cog-wheel height.17. Connect the motor and limit switches according to

the diagram.18. Test and adjust the drive system.

1. Automatic screwdriver with x-shaped ending2. A small screwdriver with flat ending3. Knife or scissors for cutting wires4. Inbus keys set5. Hex keys, screw keys set6. Driller and drills 7. Fretsaw (scroll saw)8. Universal meter

Each photo is worth more then thousand words. View attached photos before assembly. They can be found at:"Assembly instruction photographs"

An additional person to help is required when fitting-up the aluminum rails.

Rails fitting and cog-wheel hole cutting out.

Aluminum rails fitting.

Action Order.

Cog-wheel hole

Tip: Proper rails fitting is a key to shutter drive operation. Especially important issues:

Drive cog-rim shall be fitted at the right side of the dome (front view) with cogs facing inwards dome.

Rails fitting shall start from dome's front. Rail ending shall stick out the shutter front edge by approx. 1cm.

Do not try to screw on both endings of the rails firstly, it will disable proper adjustment of rails bending.

The hole shall be carved out in right part (from front view) of the dome, at its top and at 2cm distance from back panel end (see the next picture). The hole shall be 8cm wide, the same as the plates fastening the motor. Hole's position height must match vertical dome's edge.

The easiest way to carve out the hole is to drill two holes first and then use a fretsaw (scroll saw) to obtain the exact shape.

1. Both rails shall bend uniformly (rails shape shall fit dome's curvature)

2. The same rail distance from shutter edges3. The same rail spacing at shutter ends4. Rails must not "wave" compared in vertical view with

dome's sides more than 0,5cm.5. Rails fitting position shall be adjusted in a way that

the shutter must not protrude dome's curvature.

1. Assembly shutter rails (wheels and side bracket holders) according to attached photos.

2. Screw on cog-rim at the right side of shutter. Then - keeping uniform distance (height) between rail and shutter edge - screw on succeeding bracket holders.

3. Proceed with left rail in similar way.4. Put the shutter onto the dome and check if it slides

at correct height compared to dome's curvature. Adjust rails height if neccesary. Guide rails shall move at 1.5cm distance above hihgher part of shutter track.

Fitting up the shutter.

Action sequence.

1. Unscrew rear movement limiters.2. Fix eight holders securing the shutter from being

dragged away by strong wind (four holders at each side).

3. Screw on the decorative handles at the front and rear of the shutter.

4. Put the shutter onto the dome.5. Fix limit switches clamp.6. Screw on the rear movements limiters.

Mind correct orientation of shutter front and back. Shutter front has a specific incision which matches front panel of the dome. Securing holders shall be screwed on in a way to touch aluminum guide rails very slightly.

These rails shall be under holders rollers. It is more convenient to start shutter assembly from the dome's back. Properly mounted shutter has to open and close without resistance nor abrasion.

The shutter without engines tends to fall down (it is not balanced well). Since you have automatics installed,the shutter is restrained by the driving cog-wheel. It is especially dangerous when the shutter falls down during opening. The shutter shall be opened and closed in two steps - first grab the shutter at the front, open it just halfway and check if it does not start to fall down. Then walk around to the dome's backand open the shutter to the end position,holding it by the rear handle.

If the shutter brush (abrades) against dome's side, fix inside the dome a wooden strut 1015 mm long, as shown on a photo below.

Shutter drive assembly.

Action sequence.

1. Screw on motor main holder (L) at dome's top with the use of five screws.

2. Fix the cog-wheel (C) in drive motor module (M).3. Screw on slightly drive motor with main shutter

holder in a way that the cog-wheel would not touch shutter's cog-rim.

4. Adjust cog-wheel height so that cog-rim is at its middle point.

5. Fix end switches.6. Test limit switches operation trying to set them

active at approx. 2cm before full open/close of the shutter.

7. Press and tighten cog-wheel to shutter's cog-rim and screw on the bolts (K) fastening motor module.

8. Install motor and limit switches wiring.9. Open and close the shutter several times using

ScopeDome USB Card.10. If the cog-wheel slips off cog-rim - stop the shutter at

this point. Loosen screws fastening the motor module, then tighten the cog-wheel to cog-rim hitting 2X motor mounting plate with a hammer. Next screw on firmly four bolts fastening the motor module.

11. Test shutter drive operation again.12. Check if the shutter power cable does not brush

dome's engine during its revolution.

Shutter motor is powered by 14-core cable. Its both ends shall be fixed firmly - as not to be teared out if the dome proceeds too many turns. The cable shall be placed in a way it would not brush the dome's engine.
