The rotator should rotate counter-clockwise, and stop exactly at 0. If not, go to the rear panel of the controller, and use a small screwdriver

14、to adjust the PRESET ADJ A potentiometer so that the rotator stops at exactly 0. 13. Set the PRESET control to 90 (fully clockwise), and press the PRESET switch. The rotator should rotate clockwise, and stop at exactly 450 (90; East). If not, go to the rear panel of the controller, use a small screw

15、driver to adjust the PRESET ADJ B potentiometer so that the rotator stops at exactly 450. 14.

Set the SELECT SWITCH on the rear panel to the le

Mounting the Rotator and Antenna 1.Temporarily connect the rotator unit and the con- troller using the supplied connection cable. 2.Turn the SPEED control fully

17、 counter-clockwise, and set the SELECT SWITCH on the rear panel to the right (ADJ. MODE) position. 3.Check to be sure that the POWER switch on the controller is set to “OFF,” then plug the controllers AC cable into your stations AC outlet. 4.Set the controllers POWER switch to “ON.” Verify that the

18、controllers pilot lights have become illumi- nated. 5.Press the LEFT (rotation) side of the seesaw switch, and continue to hold it until the rotator reaches the counter-clockwise position where it automatically stops (“Left” represents counter-clockwise rotation when the rotator is viewed from the t

19、op). 6.When the rotator has reached the left “stop” posi- tion, release the LEFT switch, and check to see if the controllers indicator needle is pointing to 0 (N: North). If the indicator needle is out of alignment, grasp the edge of the bezel around the bearing window, turn it 10 counter-clockwise,

20、 and pull it off. Then, grasp the needle at its center and pull it straight off, re- place the needle to 0 (straight up), and replace the bezel. 7.Just above the round connector jack on the rotator unit, you will observe two raised calibration marks (one each on the “rotating” bell and “fixed” base

21、of the rotator). These two marks should be directly aligned with each other. If not, place a small piece of masking tape on the rotating bell and the fixed base of the rotator unit, and make a calibration mark will be used to verify the amount of rotation in the next step. 8.Press the RIGHT (rotatio

Now check the indicator needle, which should also have rotated fully 360 so as to be pointing exactly to 0. If the indicator needle is not pointing exactly to 0,

23、go to the rear panel of the controller, and use a small screwdriver to adjust the FULL SCALE ADJ po- tentiometer (see below) so that the indicator needle points exactly to 0. 9.Press the RIGHT switch again, and continue rota- tion to the right.

Installing the Dial Heading Sheet A clear plastic round dial heading sheet is provided with the kit, which can be installed with north at any position you desire. This is particularly useful when you need to have south at the top of the dial (or east or west) inste

To install the heading scale: ?Turn on the POWER switch and press the seesaw switch to set the indicator needle to 0 (straight up), then turn off the POWER switch. ?Grasp the edge of the bezel around the bearing window, turn it 10 counter-clockwise, and pull it off. ?Note the position o

Before mounting the mast to the rotator, a single hole must be drille

32、d through the bottom of the mast to accommodate an anti-twist support bolt used in the base support clamp halves. 1.Drill a 9 mm diameter hole through both walls of the mast, centered 50 mm from the mast bottom (see Figure 1). Ensure the drill is maintained perpendicu- lar and centered when making t

33、he holes, to ensure proper alignment of the holes in the mast with those in the base support clamp. 2.Attach the rotator to the towers rotator mounting plate, using the supplied M8 x 16 bolts and spring washers. It is recommended that the tips of the bolts be lightly dipped in lubricating grease, to

34、 ease dis- assembly in the future (see Figure 2). 3.If a thrust bearing (such as the optional Yaesu model GS-065) is to be utilized, mount it on the top of the tower (see Figure 3) using the supplied hardware. 4.Partly tighten the mast clamp ? to the rotator hous- ing using the supplied M8 x 25 bolt

35、s ?, spring washers and flat washers (see Figure 5). 5.Using a “gin pole” or other raising fixture, insert the antenna mast through the bearing from above, and set the mast in the rotators mast clamps, then partly tighten the mast clamps using the supplied M8 x 70 bolts ? and spring washer. One side

36、 of the clamp has ridges on either side of the bolt holes; the bolts should be inserted from this side, so the ridges hold the bolt head from turning. 6.Pass the supplied M8 x 95 screw ? through the mast clamps and through the mast, then partly tighten it using the supplied square nut ?. 7.Partly ti

37、ghten the thrust bearings mast bolts, so as to center the mast in the thrust bearing. When you are satisfied that the mast is centered, tighten the thrust bearings mast bolts to secure the mast in place. 8.Now tighten all the nuts of the mast clamp except for the square nut holding the M8 x 95 bolt

38、through the mast clamps and mast. Leave the square nut only lightly secured at this time. Do not over-tighten the nuts on the mast clamps. They should be tight- ened until the spring washer becomes flat, then tight- ened further by to one turn maximum. 9.Install the rotator control cables round plug

39、 into the jack on the side of the rotators base, and tighten the connector ring to secure the connector. Slide the rub- ber boot over the connector; while putting a slight amount of inward pressure on the rubber boot, use electrical tape to secure the back end of the rubber boot to the cable. This s

40、light inward pressure on the rubber boot will enhance the weatherproofing of the installation. Secure the control cable to the tower in several places, using electrical tape and/or UV-re- sistant cable ties. 10. Get a ground crew member to set the controller to 0 (North), which corresponds to 180 of

41、 rotation clockwise from the left “stop” point. During rota- tion, watch the M8 x 95 bolt to be sure it does not bind between the mast and the mast clamps. If bind- ing is observed, stop rotation and make slight ad- justments to the thrust bearing and/or mast clamps, so as to eliminate the binding.

42、If the M8 x 95 bolt is not binding, you can go ahead and tighten the square nut securely. 11. Provide sufficient slack in the coaxial cable such that the antenna can rotate over its full 450 range without putting any tension on the coax (see Figure 8). Secure the coax to the tower, using electrical

43、tape and/or UV-resistant cable ties. 12. Installation is now complete. If you have scratched through the melamine coating of the rotator during installation, you may wish to apply several coats of clear acrylic spray to help protect the bare metal from corrosion. After installation is complete, test

44、 the sys- tem by operating the rotator through the entire range of its rotation. It is helpful to do so with the help of an observer, so that rotation can be stopped if some obstruction, binding, or tension on the coaxial cables turning loop should be encountered during the per- formance test. Insta

45、llation Note If using a roof tower with a long mast between the top of the tower and the antenna, the use of a “Guy Bearing” is highly recommended. The Yaesu GS-050 and GS-065 include guying “ears” which allow attachment of guy cables. As installing a guying system may cause the center- lines of the

46、 guy bearing and the rotator to become mis-aligned, be certain to check the roof tower attachment and guy cable alignment to ensure that the mast is straight.
