Jog Controls at the Cabinet
The Model 8250 has a
jog panel
with antenna jog controls similar to
those on the front of the Model 8200 ACU.
Figure 2-2
Model 8250’s jog panel inside the cabinet largely duplicates the jog
panel of the Model 8200 ACU. Shown here with display option.
The Polarization, Elevation, and Azimuth controls are the same as on
the ACU. When the antenna is in motion, LEDs on those controls
light up blue,
whether the ACU or the drive cabinet initiated the motion.
Three additional jog-
panel buttons allow the 8250’s operator to move
the antenna without the ACU:
• Local
When
local
is selected, the operator can control the antenna from the
drive cabinet’s jog panel and this LED will be illuminated green.
• Slew
If
slew
is selec
ted, the cabinet’s jog controls will move the antenna at its
slew speed and this LED will be illuminated green.
• Toggle
When this is
not
selected, the antenna moves only while the operator is
actively depressing a jog button. When toggle is selected, the antenna
starts moving at a button press
and keeps moving until an operator presses the
same button again
(LED is illuminated green). Either way, limit switches
are still in effect.
