Conﬁguration of NITEC System

GENERAL

This device is called Robot Positioner (EPR-203).

By installing Parabola antenna for TVRO and con-

trolling Satellite Selector, it automatically directs

the Parabola antenna to the designated satellite.

This is done by automatically moving the ap-

propriate Azimuth (AZ) and Elevation (EL).

This manual only contains instructions for

mechanical parts, and we recommend you also

refer to "Satellite Selector Operation Manual".

We hope that you gain more knowledge on this

device to take a full advantage of its features and

to take proper maintenance care. We are certain

that you will be satisﬁed with this device when

used correctly.

FUNCTIONS

INSTRUCTION

-1 Installation of Robot Positioner

-2 Installation of Dish

1. Do not install the Robot Positioner up-side down.

Bullhead installation side should be at the bottom.

2. Set "North" so that the arrow points to the direction of North.

3. Use bolts that match four 1/2" -13UNC screws on Bullhead installation side.

4. Use four 14 mm holes on Dish or Wedge Adapter installation ﬂange side for installation of Dish or

Wedge Adapter.

5. Two persons should carry the Robot Positioner which weighs 60 lbs. (27 kg)

6. A spare fuse (4 A-250 VAC) is included in the carton.

Do not damage or lose this fuse.

To maintain its accuracy and to utilize its func-

tions to their maximum, the Robot Positioner

needs to be installed on a ﬂat and sturdy base.

Therefore, when installing directly on the ground,

install on concrete with foundation bolts. If in-

stalling on the rooftop of a building or similar

position, install on the foundation similar to that.

Make sure that a big vibration from the surroun-

ding area does not reach the Robot Positioner.

The installation procedure is that ﬁrst, place in-

stallation legs on concrete foundation, position

foundation bolts through four holes on installa-

tion legs, and ﬁx the legs ﬁrmly with nuts. Next,

place the bottom of post on the legs and ﬁx them

with four bolts. Then, cover the post with

Bullhead. Put them together with bolts around

the Bullhead pipe. These bolts are 3/8" -16UNC

bolts.

The next step is to ﬁx the Robot Positioner into

Bullhead. We recommend you use a lift for in-

stallation. After you put the Robot Positioner on

Bullhead ﬂange side, use 4-1/2" - 13UNC bolts

underneath the case to secure Positioner and

Bullhead in their place. (When a lift is not

available, work with two persons or more). Then,

turn Bullhead around to match the "North" make

and ﬁx it with bolts on Bullhead.

All this series of work should be done using

gauge and other instruments to carefully main-

tain its horizontal and vertical position. At last,

connect the extension cable from Robot Posi-

tioner to Junction Box and this completes the in-

stallation work.

Follow the instructions by Dish manufcturer.

Piece the Dish assemble installation side correctly

to the Dish or Wedge Adapter ﬂange side on

Robot Positioner. If dish assemble installation

side does not match the Robot Positioner installa-

tion side, place an installation metal instrument

between both sides and ﬁx the Dish in its place.

Once the Robot Positioner is installed, there is

no need for readjustment mechanically or

electrically.

Please note the following at the time of

installation.

BEFORE OPERATION

DAILY MAINTENANCE

-3 Connecting the Attachement Cable

Robot Positioner has a 4.6 ft (1.5 m) Attachment

Cable with 18 numbered wires at the end, and

each wire is connected to an U-shaped pressure-

attached terminal. This terminal connects to the

terminal block of Junction Box, and then to the

terminal block of Rear Panel of Satellite Selector

via External Cables. The connection to terminal

block of Junction Box is done with matching the

wiring number of External Cables connected to

the Rear Panel of Satellite Selector with the

wiring number of Attachment Cable. This means

matching the wiring numbers indicated on

Attachment Cable of Robot Positioner and the

numbers indicated on the terminal block on Rear

Panel of Satellite Selector by using the External

Cables and connecting to the terminal block of

Junction Box.

When installation and cleaning of the device are

completed, you are ready to operate the

machine. Check if Attachment Cable from the

Robot Positioner is connected to the Satellite

Selector.

Also, make sure all nuts and bolts are securely

tightened. When you have checked that all parts

are correctly attached, you may turn on the

power switch to the Satellite Selector. For the

operation of Satellite Selector, refer to "Satellite

Selector Operation Manual"

To maintain the device's accuracy and to fully

utilize its functions, the following inspections

should be practiced regularly. In case you ﬁnd

any trouble, switch oﬀ Satellite Selector and call

the qualiﬁed service personnel for repair.

[daily maintennace]

1) Do you see any impurities or dirt on the device ?

2) Does the operation noise sound normal ?

3) Is there any generation of heat ?

4) Are nuts and bolts tightened and in place ?

5) Is there any strange vibration while operation ?

6) Are there any other abnormal conducts ?

7) Are there any environmental factors that aﬀect the

operation of the device ? (tree branches, buildings,

natural phenomenon, etc.)

8) Others

Make sure not to mistake the numbers "6"

and "9" on the c abl e . Th e un d e rli n e

indicates the bottom of the number.
