Reinstalling the Electronics Box and the Magnetron/Circulator Assembly
- If necessary, secure the forked end of the magnetron ground wire to the top left screw securing the magnetron to the circulator, using a 3 mm (7/64 in.) hex wrench.
- Place the rubber grommet around the magnetron power cable and ground wire.
- Place the new electronics box in its slot on the bottom cover.
- Place the new magnetron/circulator assembly in its slot in the bottom cover, making sure the rubber grommet protecting the magnetron wires is properly inserted over the matching cut-outs on the electronics box housing and the bottom cover.
-
Lift the magnetron slightly, and
place the LNC in its slot in the bottom cover.
The open wave guide on the side of the LNC rests directly against the magnetron/circulator assembly.
- Using a #2 Phillips screwdriver, install the three screws securing the LNC to the bottom cover.
- Loop a cable tie through the cable tie holder next to the modulator board in the electronics box.
- Using a #1 Phillips screwdriver, secure the ring end of the magnetron ground wire to the board in the electronics box.
- Connect the magnetron power cable to the port on the modulator board.
- Form a loop in the excess magnetron cable and ground wire, and secure it to the electronics box using the cable tie you prepared earlier.
-
Place the oblong rubber grommet
in the cut-out on the electronics box near the processor board.
The split on the oblong rubber grommet must be facing up, to fit correctly.
- Route the LNC cable, the antenna position sensor cable, and the status LED cable through the oblong rubber grommet, and connect them to the appropriate ports on the processor board.
-
Connect the motor power cable to its port near the edge of the processor
board.
TIP: You should use a flat screwdriver to push the motor power cable connector and make sure it is fully seated.
- Place the electronics box cover on the electronics box, making sure the rubber grommet protects the LNC cable, the antenna position sensor cable, and the status LED cable from friction with the electronics box and the electronics box cover.
- Using a #1 Phillips screwdriver, install the two small screws securing the cover on the electronics box.
- Using a #2 Phillips screwdriver, install the screw securing the motor ground wire to the electronics box.
- Using a #2 Phillips screwdriver, install the remaining electronics box screws, except the two screws adjacent to the magnetron.
- Using a #1 Phillips screwdriver, install the small screw securing the magnetron/circulator assembly to the LNC.
- Using a #2 Phillips screwdriver, install the two screws closest to the magnetron, securing the magnetron/circulator assembly to the bottom cover.
- Place the magnetron cover over the magnetron/circulator assembly.
- Using a #2 Phillips screwdriver, install the six screws securing the magnetron cover.
- Reinstall the antenna (Reinstalling the Antenna).
- Reconnect the internal power cable and the internal network cable to the ports on the side of the electronics box.
- Install a new cable tie securing the ferrite beads on the internal power cable and the internal network cable to the bottom cover.
