Mounting the Rotator and Antenna

l

 

Indoor Performance Check and Alignment

  1. Temporarily connect the rotator unit and the controller using the connection cable prepared per

the previous section.

  2. Check to be sure that the 

P

OWER

 switch on the controller is set to O

FF

, then plug the controller’s

AC cable into your  station’s AC outlet.

  3. Set the controller’s 

P

OWER

 switch to O

N

. Verify that the controller’s pilot lights have become illuminated.

  4. Hold down the 

L

EFT

 (Left rotation) switch, and continue to hold it down until the rotator reaches

the counter-clockwise position where it automatically stops (“Left” represents counter-clock-
wise rotation when the rotator is viewed from the top).

  5. When the rotator has reached the left “S

TOP

” position, release the 

L

EFT

 switch, and check to see

if the controller’s indicator needle is pointing to 0º (

N

: North).

    

If the indicator needle is out of alignment, slightly loosen the needle adjustment screw (using a

small Phillips screwdriver) on the face of the indicator, then turn the white needle adjustment
knob so that the indicator needle points precisely to 0º.

  6. Just above the round connector jack on the rotator unit, you will observe two raised calibration marks (one

each on the (rotating) bell and (fixed) base of the rotator).These two marks should be directly aligned with
each other. If not, place a small piece of masking tape on the rotating bell and the fixed base of the rotator
unit, and make a calibration mark on each piece of tape, so as to mark the current position of the bell
relative to the base. This calibration mark will be used to verify the amount of rotation in the next step.

  7. Hold down the 

R

IGHT

 (Right rotation) switch, and continue rotating to the right until the calibration

marks (from Step 6) are again precisely aligned. Now check the indicator needle, which should also
have rotated fully 360º so as to be pointing exactly to 0º. 

If the indicator needle is not pointing

exactly to 0º, go to the rear panel of the controller, and set the Adjustment Potentiometer Selection
Switch (see Figure 2) to the 

right

 position. Now use a small screwdriver to adjust the Indicator

Needle Adjustment Potentiometer (Fig. 2) so that the indicator needle points exactly to 0º.

  8. After aligning the needle to 0º, set the Adjustment Potentiometer Selection Switch back to the

left

 position.

  9. Hold down the 

R

IGHT

 switch again, and continue rotation to the right. You should observe the

“O

VERLAP

” LED becoming illuminated as rotation passes the 360º point.

    

If the 

O

VERLAP

 LED does not light up at the 360º position, the Overlap LED Adjustment Poten-

tiometer may be used to align the illumination threshold to the 360º point.

10. Check to verify that rotation automatically stops at approximately 90º (East; representing a total

rotation range of 450º from the original starting point).

11. Press the 

L

EFT

 and 

R

IGHT

 

rotation switches a few more times, verifying that rotation appears to be

normal. If so, press the 

L

EFT

 switch to return the rotator to the fully counter-clockwise (0º) position.

12. At this time, you must determine whether you wish to leave the “Left Stop”  position at North,

or whether you wish to set it to South (to allow uninterrupted rotation from southeast to north-
east to northwest to southwest, for example). 

If   you wish to leave the “Stop” at North, the

checkout process is complete. If you wish to set the “Stop” to South, again loosen the needle
adjustment screw on the   face of the controller, and rotate the needle to the “South” position.

Be certain that the rotator is fully rotated to the “L

EFT

” position in either case

.

The position of the “Left Stop” can be set to whatever position you like (North, South,
East, or West). Just remember where you have set it,  because the antenna must initially
be aimed in the same direction when it is installed on the mast (see next section).

13. Turn the 

P

OWER

 switch O

FF

. This completes the ground-based testing of the rotator and controller.
