AlfaSpid Rotator www.alfaradio.ca Page 8

Turn the unit OFF.

While holding the

button depressed, turn control unit back on. This

will now show

on the display.

This feature can be used if, for any reason, the direction of the antenna becomes incorrect.

This may be caused by antenna to mast slippage or incorrect initial alignment. Re-alignment

may be necessary.

IMPORTANT:

Azimuth

In order to set the limits for both the Azimuth and the Elevation sections

of the rotator, first always start by setting up the azimuth section by

pointing the rotator to 0 degrees or true north. Now reset the controller

as previously outlined above. The controller is now set for azimuth.

The AlfaSpid rotator is now set at the counter-clockwise end of its

normal rotation range. Normal rotation range is in a clockwise direction

for 360 degrees.

From the reset position, you can rotate counter-clockwise an additional

180 degrees in over-travel, as well 360 degrees clockwise, plus an

additional 180 degrees into clockwise over-travel.

Counter-clockwise over-travel is indicated by a steady dot above the

over-travel icon

. . Rotation past 359 degrees into the clockwise

over-travel is indicated by a blinking dot above the over-travel icon.

Elevation

Elevation, must be set to zero. To do this the controller and rotator must

be positioned to zero degrees, both electronically and mechanically.

Using the display down arrow ( or the mouse ) move the rotator to the

full travel, which should be about (- 21.0 ). If the rotator stops and the

display is not -21.0 then the mechanical stop in the rotator has been

activated. After display on the controller reads -21.0 (or its lowest value)

reset the unit by pressing the “F” button and turning on the power at the

same time. Again, using the display down arrow ( or the mouse ) move

the rotator to the full travel, which should be about (- 21.0 ), repeat this

until there is no more travel.

Press the display up arrow until the 10.0 degree mark is met. Do a

reset. Test for a full 180 degrees of travel. If it travel is 180 degrees or

more then setup is correct. If it does not then repeat the process until it

does. See section on “PP” for minor adjustments
