Installation of the dome rotating ring

1. Assemble the bottom of the rotating ring on the

observatory's crown. To combine elements of the

ring, use the side supports of the dome rotation

mechanism. Center the ring on the observatory's

crown.

2. Attach the bottom of the rotating ring of the dome

the observatory's crown using at least 16 x M12

bolts. The more mounting screws the better. First,

use the holes next to the side supports. Note that

these bolts are the only security elements protecting

against removing the dome from the observatory's

building in the case of very high winds. For fixing the

rotation ring to the the observatory's crown, you can

also also use Hilti anchors.

3. Assemble the upper part of the dome rotating ring

on the bottom part of the rotating ring. For

connecting the upper ring segments, use

countersunk screws. Please note that the ends of

the bolts should not touch the side supports. Use a

rubber hammer to align the joints of segments.

Connections should be as smooth as possible.

Uneven joints will cause rapid wear of the main rolls

of the rotation mechanism. For connecting the

segments, use the connectors mounted on their

ends.

4. During the installation, please pay attention to the

wires of the power contacts system between

stationary and movable part of the dome's drive.

Their failure will then be very troublesome to repair.

5. Adjust the height and location of the power contacts

of the movable part so as to slightly touch the brass

rolls supplying the power. Check the power supply

contacts if they completely overlap with brass rolls

and do not cause a short circuit between the rolls.

6. After this stage, the rotation drive mechanism is

completely assembled.

The entire dome will be built on the rotation ring. At

subsequent stages of assembly access to it will be

very difficult. Before the next stages of assembling

you should very carefully adjust it and test its

performance.

Testing the rotating ring assembly

a) In a few places measure the diameter of the rotating

ring using the laser. The deviation of individual

measurements should not be greater than + / - 3 mm.

b) Check that all the main rolls are well pressed into the

upper ring of the drive. If not - it is necessary at this

point, adjust their height.

c) Check that the upprer ring is well leveled. Electronic

spirit level should show 0 degrees + / - 0.1 degrees at

every place of the ring. Measurements should be

done at each of the eight puds of the lower ring.

If the rotating upper ring is not well leveled, adjust the

height of the rolls so that the ring was perfectly

horizontal, while not wiped on the side supports. The

distance between the ring and side handles should be

about 5 mm. During the adjustment you should pay

attention to whether the cog rim of the rotation

mechanism fits the cog wheel of the motor.

d) Check that the side rolls of rotation mechanism are

not unduly pressed against the cog rim. Between the

side roll and the cog rim there should be a slight gap

ofabout 0.5mm. If the rolls are squeezed too tight,

adjust the position of the side supports.

e) A well adjusted ring should be able to rotate freely

and effortlessly with the force of one hand.

f) Before further installation stages you should

repeatedly rotate the upper ring left and right, noting

that it does not touch anywhere on the elements of

the lower ring and the rotation takes place smoothly

and without resistance.

g) If the motor blocks the movement of the base ring, try

to loosen the bolt mounting the cog wheel and move

it slightly to the center of the ring so that the cog

wheel will not be in contact with the cog rim.

h) If the ring drive works properly, you are ready for

further stage of the dome's assembly.

Assembly and sealing of the outer

casing panels

Embedding and assembly of the dome

base panels

Installation of the dome we start from installing four

panels the outer casing on the top of the rotating ring.

You should seal:

- the connector between the casing and the upper ring

- joints between sections of the outer casing

Each of the four parts of the outer casing should be

tighten by the countersunk screws M8x20 into the upper

part of the ring. The holes - previously prepared in the

manufacture should be used to do it. Screw heads should

not protrude above the plane of the outer casing. During

the assembly of the casing you should pay attention

whether it is centrally mounted on the ring. At the end, the

inner edges of the outer casing you should tighten by the

M6x25 screws.

On the ring with mounted and sealed outer casing we put

the dome base panels and screw them on together.

Installation is best to start from the left panel of the base.

Then we combine the left side of the base panel with the

front panel of the base. At the end attach to them, right

panel base.

These three elements together we screw on into the

upper ring of the drive using the prepared holes and the

hex bolts M10x25. Under the bolts that connect the base

panels with the upper drive ring, please use washers

M10.

During installation you should use the markings on the

elements and the upper part of the base ring, matching

them to each other in such way: 1-1, 2-2, 3-3, etc.

The key issue for the integrity of the dome and its

protection from the rain is to seal all threaded outer

casings. This casings help to drain the water out of

the dome.

When installing panels and the outer casings you

should pay attention to the power cord connected to

the movable contacts. The cable should be piped to

the inside of the dome. Route the cable using the

prepared holes.

S4 Assembly and sealing of the side

panels

Installation of the rear panel of the

dome

Installation of the

shutter drive

Embedding the shutter and the

shutter handles assembly

Appropriate panels of the dome we screwed on to the

panels of the base. We screwed on the left panel of the

dome to the left panel of the base, and the right panel of

the base to the right panel of the dome. At the end, the

upper front panel of the dome should be screwed on to

the front panel.

During installation you should use the markings on the

elements matching them to each other in such way: 1-1,

2-2, 3-3, etc.

The edge connecting the panels with the main base of the

dome panels should be sealed around the perimeter by

the rubber seal.

After this stage, we will have screwed on all the panels

except the rear panel of the dome and the shutter. The

next step is to screw on the rear panel of the dome which

crowns this building phase of a sphere of the dome. Then

we should just install the shutter drive and mount it on the

dome.

The shutter drive we screwed on the top of the dome to

its sides using five hex screws M10x30 on each side of

the dome. The steel bar of the drive should be additionaly

screw on to the gutter of the dome on each side using two

countersunk screws. Distance between the outermost

edges of the shutter must be adjusted so that was 140 cm

(+ / - 1 cm) around the entire perimeter of the dome

windows.

Before mounting the shutter we should declutched the

cog wheel of the drive by screwing off the four screws

fixing it to the flange mounted on the drive axle. If he will

mount the shutter with a crane, we can skip this step.

Disengaged the gear helps in mounting the flap. This

makes it easier to match the holes in the cog rim with the

cog wheel of the shutter drive.

Note the correct front-rear orientation of the shutter.

Embed it in accordance with the ribbing on the sides of

the dome.

The easiest way to install the shutter is to do it manually

by applying the shutter from the back of the dome. It can

also be installed by crane by embedding it on the top of

the dome.

To hold the shutter in the back end position there will be

need of support at least three persons, becouse the

shutter is quite heavy. Doing it manually there will be a

need of support at least five people - two on each side

and one with long enough bracket to sustain the shutter

on the center.

After embedding of the shutter we screw on its side

handles. We screwed them on from the outside of the

side panels. The handle on the top of the dome must be

screwed on using the screws fixing the shutter drive.

Handles should be installed in such a position to slightly

tighten the aluminum strip with leading shutter rolls.

Mounting screw heads of the handles should be placed

on the outside of the dome in such way to avoid their

rubbing on the shutter leading mechanism.

Side handles of the shutter have two functions in the

dome's functionality:

All adjustments of the shutter drive (motoreducer's

height, handles location) should be done in such way to

have the cog wheel heavily pressed to the cog rim of the

shutter.

While applying the shutter we should pay attention to

the shutter side rolls. We can easily damaged them

during assembly by hitting them on the side panels

of the dome.

Note: When you place the shutter on the dome it

could be unstable. It should be locked on the teeth of

the cog wheel. The cog wheel must be secured by

screwing it on to the flange mounted on the drive

axle using the four screws.

When mounting the drive we should pay special

attention to the cog rim and the cog wheel of the

drive. The cog rim around the entire perimeter of the

dome should be closely pressed against the cog

wheel. In particular, note the extreme (open-closed)

position of the shutter.

1. They provide the necessary up/down pressure for the

cog rim of the shutter

2. They protect the shutter before removing it from the

dome by strong wind

Left/right rolls help to correct positioning of the

shutter during its the opening and closing.

ver 2.0 automatics

At the end (after the installation of automatics), we screw

on the inner casing panels to the side supports of the

lower drive ring.

During the assembly it should be noted that the inner

casing do not wipeth anywhere on elements of the dome.

The inner edges of the casing we screw on using screws

M6x25. And this is the end of the dome assembly. Please

follow only the final test to see if the dome continues to

rotate freely.

Complete ScopeDome automation system consists of

following components:

Optionally, the card can be connected to:

Properly assembled dome should be able to be

rotated by hand with little effort in both directions

around the entire perimeter, with no audible effects

of friction and jams.

To verify the correctness of the dome assembly

please (manually or by using the rotary drive motor)

rotate it several times in both directions.

B. Installation of encoder

- attach the stationary part of the ScopeDome USB

card to the pier

- attach the rotation motor inverter close to the motor

- connect the card with the rotation motor inverter

according to the scheme

- connect the inverter with the dome rotation motor

- connect the power (230VAC) paying attention to the

order of the wires L / N / PE.

- turn on 230VAC power on the card

- press the CW and CCW buttons to check the dome

drive.

- on one of the dome side supports attach the dome

position encoder so that the cog rim passes through

the fork of the encoder.

- adjust the encoder's position so that the end of its

fork was in the middle of the cog rim teeth

- connect the encoder and the card

- very slowly rotate the dome and make sure that the

encoder does not touch the cog rim teeth during the

dome's rotation

From 2011, we introduced for sale a new encoder

module, mounted on the rotation drive cog wheel

axis (shaft) (behind the motoreducer). It allows you

to avoid the difficulty of adjustment of the sensor and

is much more resistant to inaccuracies in assembly

and dust. It is slightly more expensive than the

standard solution - but we believe its benefits and

durability compensates slightly higher price for the

item.

Proper connection of the phase (hot) power supply

wire is crucial for the correct functioning of the

automation. Due to security reasons, do not forget

under any circumstances connect the security

cable PE.

The speed of the dome can be adjusted by a

potentiometer on the front panel of the inverter.

The encoder is a very delicate and easy to be

damaged during assembly and adjusting the drive.
