User manual YAESU G-550 APRS MANUAL

[. . . ] The factory-lubricated rotator unit is housed in weatherproof melamine resin coated die-cast aluminum, to provide maintenance-free operation under all climatic conditions. The controller unit is a handsomely-styled desktop unit which indicates antenna elevation offset from zenith up to 90° in both directions. Please read this manual carefully before installing the G-550.

[. . . ] 1 If any of these items are missing or appear to be damaged, save the carton and packing material and notify the shipping company (or dealer, if purchased directly at his shop). Before proceeding with installation, confirm that the AC voltage label on the rear of the Controller matches your local line voltage: either "117V" for 110 to 120 VAC, "220" for 220 to 240 VAC. If the labeled voltage range does not match, return the controller to the dealer from whom you purchased it (different power transformers are installed for the different voltage ranges). Note that cable is not included with the rotator, as the length must be determined caseby-case. Contact your Yaesu dealer to obtain the length of cable your installation requires. For runs of over 100 feet, use #18 AWG instead of #20 AWG. PAGE 2 G-550 INSTALLATION MANUAL CONTROL CABLE PREPARATION & CONNECTION 1. Assemble the cable according to the following diagrams. Connect each wire to the terminal on the rear panel of the controller, making sure to match the numbers on the pins (terminals 7 and 8 are not used), 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 lamp should light and the meter indicate approximately 90° (center). The 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 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 cable connections. When everything checks out in the above steps, slide the water resist cap over the connecter on the rotator. Remove the cable clamps from the controller, clip them over the cables, and screw them back onto the controller. Notes on Controller Operation: H If both UP and DOWN switches are pressed at the same time, the rotator turns clockwise (up). H Remember to turn the controller off when the rotator is not in use. Terminal 7 is not used. Tin the wire with solder. Make sure to insert the Water Resist Cap first. PAGE 3 G-550 INSTALLATION MANUAL ELEVATION INDICATOR CALIBRATION Turn the controller off and note the position of the meter needle, which should be precisely at the left edge of the scale. [. . . ] 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 as shown in Figure 2. Center the boom carefully, and alternately tighten the nuts on each U-bolt 1/2-turn beyond the point where the spring washers are flattened. Figure 1 Figure 2 PAGE 5 G-550 INSTALLATION MANUAL Be sure to leave enough slack in both the elevation control cable and the coaxial cable feedline around the azimuth rotator so the antenna can rotate 180° without straining the cable or feedline. For dual parallel arrays, feedlines should be taped to the boom on either side of the rotator, with enough slack left to allow 180° rotation without stressing the feedlines. The rotator motors are rated for five-minutes intermittent duty. [. . . ]
