Actuator Connection
Remove the rear cover of the actuator motor. Inside the cas­
ing is a terminal strip. Connect the appropriate wires to the
connections on the strip. Be sure to use the cables recom­
mended in the preceding chart. Route the wire through the
rubber seal and put the case back on the motor. Be sure that
the gasket is properly seated for a weather-tight seal. The
actuator should then be connected to the 5 screw terminals
on the rear of the UST-9000. Make sure that the proper con­
nections are made. Any improper connection can cause per­
manent damage to your system.
Actuator Set-Up
The actuator inner tube should be retracted as far as possible,
leaving only the pivot socket exposed. The satellite position
display on the UST-9000 should read 000 . If the display is
not at 0, press the Clear Counter button on the back of the
receiver. Once the counter is at 0, press the East key until the
counter displays 0 1 0 . Press the Lower Limit button on the
back of the receiver. Move the antenna all the way to the
east. Press the West key to reverse it about 10 counts. Press
the Upper Limit button on the back of the unit.
NOTE: The Up and Down Limit buttons on the back of the
UST-9000 are used to stop the travel of the antenna in both
the east and west directions. If there is some kind of physical
obstruction or other reason that the antenna should not trav­
el the full distance of its arc, the Up or Down limit should be
set to stop the travel. To set the limit, advance the antenna to
the farthest position it should travel. Press the Down button
(for a western position) or the Up button (for an eastern
position).
IMPORTANT: BE SURE TO SET BOTH THE UPPER
AND LOWER LIMITS AS DESCRIBED ABOVE. IF THE
LIMITS ARE NOT SET THE ACTUATOR WILL NOT
WORK PROPERLY.
Additional Limit Settings
The normal limit of travel for the actuator arm is about 18
inches. If the most easterly satellite cannot be reached by the
antenna when the actuator arm is fully extended, an internal
limit switch should be adjusted.
Remove the back case of the actuator motor housing and
locate the red limit switch and cam. Loosen the two screws
holding cam. Turn the cam clockwise, until the screw head is
located in the center of the slot. Tighten screws and replace
actuator case. Press the Counter Clear switch on back of the
unit. Press the East key to move the antenna to an eastern
satellite. Move the antenna about 10 counts beyond the sat­
ellite and press the Upper Limit switch.
If the eastern satellite is still out of range repeat the preceding
steps and rotate cam further. Be sure to reset Upper and
Lower limit switches on rear of unit.
before replacing actuator case. If actuator limit
cam is not secure it will cause permenant damage
to your unit.
