[. . . ] Your control cables should have six conductors each of at least #20 AWG gauge (if less than 100 feet long). Assemble the cable according to the following diagrams. Connect each wire to the terminals on the rear panel of the controller, making sure to match the numbers on the pins, and insert the connector to the Jack on the rotator. On the controller, make sure that the POWER switch is in the "OFF" position, and connect the line cord to the AC power outlet. The meter lamps should light and the ELEVATION meter indicate to the center of the scale (90°). The elevation rotator should turn as the meter indication moves to the right. Release the UP switch and confirm that the rotator slowly stops. Repeat step 5, pressing the DOWN switch instead of the UP switch. The elevation rotator should turn in the opposite direction as the meter indication moves to the left. If operation does not occur as described above, check for a wiring error in the elevation cable connections. The azimuth rotator should turn counterclockwise as the meter indication moves to the left. Release the LEFT switch and confirm that the rotator slowly stops. Repeat step 8, pressing the RIGHT switch instead of the LEFT switch. The azimuth rotator should turn clockwise as the meter indication moves to the right. If operation does not occur as described in steps 8 and 9, check for a wiring error in the azimuth cable connections. When everything checks out in the above steps, slide the water resist cap over the connectors on the rotator. Remove the cable clamps from the controller, clip them over the cables, and screw them back onto the controller. Then replace the two controller terminal covers. Tin the wire with solder. Make sure to insert the Water Resist Cap first. Terminal 7 is not used. PAGE 3 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 rotator around one full turn to exactly the same position. [. . . ] Installing the boom in the Elevation Rotator. Place one U-bolt over each arm of the rotator, and assemble one pipe clamp, flat washers, spring washers and nuts on the U-bolts. Center the boom carefully, and alternately tighten the nuts on each U-bolt ½-turn beyond the point where the spring washers are flattened. 2. Slip an 8 mm flat washer over each installed stud bolt, and then the pipe clamps. [. . . ]
