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.

-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.

-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
