G-5500 Antenna Azimuth-Elevation Rotators & Contoroller Instruction Manual
PRE-INSTALLATION ADJUSTMENT
Switch the controller off and adjust the
0. ADJ
screws beneath each meter face, if necessary, so that
each meter points to the left edge of the scale. Then turn the controller back on for the following
steps.
Azimuth Indicator
Press and hold the
LEFT
switch and allow the
azimuth rotator to turn until it reaches its end
stop. Note the precise position of the rotator
(mark the housing, if necessary), and then press
and hold the
RIGHT
switch to bring the rota-
tor around one full turn to exactly the same po-
sition. The meter should now point precisely
to 360° of the scale. If not, adjust the
FULL
SCALE ADJ
potentiometer at the upper cor-
ner of the rear panel above the AZIMUTH ter-
minals.
Press the RIGHT switch again to continue
clockwise rotation until the rotator reaches its
end-stop. The indicator should now point to
right edge (90°) of the scale.
Elevation Indicator
Press the
UP
switch to align the 180° markers
on the rotator. The meter should now point
precisely to 180° at the right end of the scale.
If not, adjust the
FULL SCALE ADJ potenti-
ometer at the upper corner of the rear panel
above the
ELEVATION terminals.
