4.4 PCB Removal and Replacement
Figure 4-3 has been changed to indicate the correct Molex pin locations
for the azimuth limit switch and the elevation limit switch.
The following procedure has been inserted for replacing the azimuth
limit switch. As a result, Sections 4.6 through 4.8 of the Installation
and Technical Manual have been renumbered Sections 4.7 through 4.9.
4.6 Azimuth Limit Switch Assembly
Replacement
1. Rotate the antenna assembly, by hand, clockwise
until it stops.
2. Remove the printed circuit board (PCB) cover,
illustrated in Figure 4-2, using a #2 Phillips
screwdriver and a
3 ⁄
8
" nut driver/socket.
3. At the CPU’s Molex connector, cut the black and
white wires from the azimuth limit switch (see
Figure 4-3). Leave about an inch of the wires still
connected for later reference.
4. At the azimuth limit switch cover, remove the hot
melt keeping the black and white wires in place
(see Figure 4-7).
