1、G-800SA G-1000SA Antenna Rotator once a rotator is mounted, however, troubleshooting may require that the tower be climbed and/or the rotator be removed and lowered to the ground! CONTROL CABLE PREPARATION Control Cable Installation In this Rotator, the user must supply and prepare the control cable
2、, per the simple instructions below. The control cable to be used should have six stranded conductors of at least 0.5 mm (#20 AWG) diameter if the cable is shorter than 40 m in length (125); if the cable is longer than 40 m, use conductors with a diam- eter of 0.75 mm (#18 AWG) or larger. 1.Disassem
3、ble the supplied round plug: slide off the rubber boot, remove the setscrew from the shell us- ing a small screwdriver, then unscrew the shell from the plug. Save the setscrew in a safe place until step 10, so you dont lose it. 2.Slide the rubber boot and the round shell over the “rotator” end of th
4、e cable. Leave enough cable pro- truding to allow easy dressing the end of the cable. 3.Using special care to avoid nicking the insulation of the individual wires, strip back 15 mm (about 5/8”) of the outer jacket of the cable from both ends. Now strip 5 mm (about 3/16”) of insulation from each wire
5、, being careful not to nick the conductors. 4.Solder the wires to the round plug pins, noting the color of the wire and the number associated with each pin for reference later. Pin 7 of the round con- nector is not used! Confirm that all solder joints are firm and cleanly made, as this part of the c
6、able will be difficult to access once the rotator is installed on top of the tower. Do not slide the shell onto the con- nector at this time. 5.Crimp the supplied pin contacts onto the wires on the opposite end of the cable, per the illustration below. 6.Referring to your notes of the wire color at
7、each pin of the round (rotator end) connector, insert the pins into the rectangular plug at the opposite (controller) end of the cable. Be sure that each wire from the round connector is routed to the corresponding pin number in the rectangular connector (i.e. 1 to 1, 2 to 2, etc.). 7.Temporarily co
8、nnect the round plug to the rotator, and the rectangular plug to the controller. Make sure that the POWER switch on the controller is set to “OFF,” then plug the controllers AC cable into your stations AC outlet. 8.Set the controllers POWER switch to “ON.” Verify that the controllers pilot lights ha
9、ve become illumi- nated. 9.Press the LEFT (rotation) side of the seesaw switch, and confirm that the rotator (when viewed from the top) and the controllers needle turn counter-clock- wise together. Stop rotation, then press the RIGHT (rotation) side of the seesaw switch, and confirm that the rotator
10、 and indicator needle turn clockwise. If rotation does not occur as indicated, turn the POWER switch “OFF,” and re-check your cable connections. 10. If the rotator and controller are working as described, replace the plug shells, setscrew, and rubber boot (removed in step 1). Assembly of 6-pin Plast

12、d to verify the amount of rotation in the next step. 8.Press the RIGHT (rotation) side of the seesaw switch, and continue rotating to the right until the calibra- tion marks (from step 7) are again precisely aligned. Now check the indicator needle, which should also have rotated fully 360 so as to b
13、e pointing exactly to 180. If the indicator needle is not pointing exactly to 180, go to the rear panel of the controller, and use a small screwdriver to adjust the FULL SCALE ADJ po- tentiometer (see the drawing to the right) so that the indicator needle points exactly to 180. 9.Press the RIGHT swi
14、tch again, and continue rota- tion to the right. You should observe the OVER- LAP LED becoming illuminated as rotation passes the 180 point. If the OVERLAP LED does not light up at the 180 position, the OVERLAP LED ADJ potentiometer (on the rear panel of the controller) may be used to align the illu
15、mination threshold to the 180 point. 10. Check to verify that rotation automatically stops at approximately 270 (West; representing a total ro- tation range of 450 from the original starting point). 11. Press the LEFT and RIGHT (rotation) switches a few more times, verifying that rotation appears to
16、 be normal. If so, press the LEFT or RIGHT (rota- tion) switch to set the rotator to 270 (West). 12. Set the SELECT SWITCH on the rear panel to the left (OPERATION MODE) position, and turn the POWER switch “OFF.” 13. This completes the ground-based testing of the ro- tator and controller.
