Due to the wide variety of towers available, eachinstallation will have different requirements. Thegauge of the 8-wire cable to connect the controlunit to the rotator depends upon the distancebetween the rotator and control. The longer thedistance, the larger the diameter of the wirerequired. Various antennas or beams requiredifferent installation methods. (See Table 1).

CAUTIONSInstall properly and safely

Towers, often the highest metal parts in the vicinity, require caution duringerection and placement. Extreme care must be taken during erection so thatmetal towers and beams do not contact power lines even if the beams slip orrotate, towers fall or fracture or metal wires blow in the wind, etc.

Metal towers or other position mechanisms must be placed so that if theyfracture or blow over in high winds, they cannot contact power lines, be ahazard to individuals, or endanger property.

When not mounted within a tower with a thrust bearing, as shown in Figures 6and 7, the rotator must be DEBATED.

Page 3: Ph: INSTRUCTION MANUAL - QSL.net MANUALS/ANTENNA...308 Industrial Park Road Starkville, MS 39759 USA Ph: (662) 323-9538 FAX: (662) 323-6551 T-2X / T-2XX TAILTWISTER TM Rotator T-2X

Metal towers must be grounded properly at the tower location before the tower iserected. This is to minimize electrical hazard and the possibility of lightningdamage. DO NOT bury bare aluminum wires or stakes in the ground. Use copperground stakes. The service entrance ground should be checked. The householdconvenience outlet should be the 3-prong type (grounded back to the serviceentrance).

• The Control Box is not weatherproof and must be located in the house, hamshack or other protected location.

• Read this manual completely before proceeding.The Tailtwister rotator has been carefully designed and manufactured to give manyyears of trouble-free service when carefully and professionally installed. It consistsof the strongest and best commercially available components.

TYPES OF INSTALLATION

There are three general types of installations (seeFigures 4, 5 and 6).

l. The recommended Installation is an "Inside"Tower Mount with a thrust bushing or bearingto provide support and resist high wind loads.

When the rotator is properly mounted thisway, it can be rotated to turn an antenna orbeam of 20 square feet (1.86 m2) wind surfacearea. The wind loading during storms, therotational inertia of the beam and unbalancedweight are more important than the deadweight of the beam. It is important tominimize the height of the beam above therotator to minimize the overturning forceinduced in a high wind (see "UnbalancedWeight" and "Wind Pressure").

2. An "outside" Tower Mount (see Figure 6) isoptional. The rotator is not well protectedbut the installation is simpler. With an"Outside"Tower Mount, the rotator must bederated to 10 square feet (.93 m2).

UNBALANCED WEIGHT AND WINDPRESSURE

Unbalanced Weight: Weight should be asclosely balanced as possible. Unbalancedweight creates a bending moment of forcewhich is concentrated on the mast at the pointwhere it is clamped to the rotator. Thismoment tends to strain the mast at that pointand also to bind the ball bearings by creatingexcessive downward pressure on one side andupward pressure on the other. Such unbalanceplaces additional stress on the motor geartrain. Unbalanced weight becomes critical asthe distance from the antenna boom to theclamping point at the rotator is increased.

2 Wind Pressure: Wind pressure against the,

boom and elements produces a bending forceon the mast which can cause the same stressesas unbalanced weight. To strengthen theinstallation to withstand unbalanced weightand wind pressure the top mast should be asshort and as strong as possible. In multiplearrays the antenna with the most wind areashould be closest to the rotator.

3. A telescoping or other type mast (see Figure7) can also be used. This installation issimilar to Number 2 above and requires theoptional Heavy Duty Lower Mast SupportKit and must be derated to 10 square feet

In order to distribute the bending stress andprevent fracture of the mast, the T2X rotatorincludes a specially designed steel clamping plateto clamp the mast to the rotator;

After procuring the type of tower or otherpositioning mechanism of the owner's choice, thenext step is to wire the rotator to the control boxand check out its operation prior to installation.

WIRING AND CHECK-OUT

A. Decide the wire gauge (size) required andprocure the number of feet of the propercable (see Table 1).

E. Turn the power switch on. The meter shouldbe illuminated.

F. Depress the "Brake Release" (center) lever,then release it. An audible click should beheard in the rotator. This is the solenoidoperating the brake wedge.

Table 1

Figure 2Control Cable Connector Attachments

NOTE: The specifications call for heaviergauge wire in two locations. Leads #1 and #2must be heavier gauge and less total leadresistance.

G

H

Depress the "Brake Release" (center) lever,hold it, and simultaneously depress the CCWdirection switch (left). The rotator shouldturn CCW (looking from the top). This is S-E-N-WS. Release the CCW direction switch;the rotator wil lcoast down and stop. Nowrelease the brake switch. The rotator is nowlocked into position.

Repeat the previous step for CW directionby depressing the brake switch first, then theCW direction switch (right). The red lampsshould indicate direction of rotation.

C. Temporarily attach the 6 5/16"-18 x 1 5/8"screws (Item 140) to the bottom of the rotorunit.

D. With the rotator sitting in the upright positionand connected to the control unit by the 8-wire cable, plug the control unit power cordinto a receptacle.

I. Return the rotator to full CW position.

CAUTION

B. Assemble the rotor cable as shown in Figure1.

CAUTIONShorts between terminals or grounded leads maydamage the rotator. Pay strict attention to the pin

numbers on the connectors!

It is best to release the direction switch just prior tothe end of rotation (extreme CW or CCW position) inorder not to cause undue stress on the stop armand/or the gears.

ATTACHING CONTACTS TO WIRES ANDCONNECTORSince these contacts will be inserted intoconnector blocks, their tabs mustbe carefullyrounded. Unless you have a crimpinmg tool forinstalling connectors, use the followingprocedure.

Repeat for each contact. Pay close attention to thenumbered holes in the connector! Pull backlightly on each conductor to be sure each contactis locked in each cavity. Once locked in place, thecontacts may only be safely removed with anextraction tool. (Extraction tool not included).This tool consists of a tube with an O.D. of 0.129and an I.D. of 0.115. When inserted over thecontact from the front side, this tool compressesthe locking tabs, permitting easy removal.

MOUTING INSIDE TOWERThe rotator is mounted inside a tower (see Figure 44) to the flat tower plate by means of six (6) boltsfurnished in the hardware kit. Use the followingprocedure:

51. Locate the rotator in the tower directly under

the bushing. Note that the tower plate must becut out to allow the connecting 8-wire cable topass through the plate.

Use the template in the back of the manual.

2. Plug the cables together and secure the cableto the tower in such a manner that the cablewill not be strained.

3. The rotator is attached to the tower plate bymeans of six (6) bolts and lockwashers (seeFigure 4). The flat tower plate must be drilledin six (6) places using the template providedwith this manual unless the tower plate is al-ready properly drilled.

Tighten the six (6) bolts, but not to final tight-ness. Observe how the rotator turns. It mustrotate in such a manner as to turn the mastconcentrically in the thrust bearing.Trial assemble the mast to the top of the rotatorusing the U-bolts nuts and lockwashersthrough the rotator and clamp plate as shownin Figure 4. The maximum mast diameter thatmay be used is 2 1/16" O.D. We recommend1 1/2" nominal steel pipe with 1.9" O.D. instandard wall thickness of .145". For stackedarrays or very large beams, we recommendextra heavy-duty wall thickness of .200".Both steel pipes can be purchased tospecification ASTM120.

NOTE: Apply a coating of heavy-duty motor oilor grease to the threads of the stainless steel boltsand U-bolts to prevent seizing.

Figure 4Rotator Mounting in a Tower

Page 7: Ph: INSTRUCTION MANUAL - QSL.net MANUALS/ANTENNA...308 Industrial Park Road Starkville, MS 39759 USA Ph: (662) 323-9538 FAX: (662) 323-6551 T-2X / T-2XX TAILTWISTER TM Rotator T-2X

On any inside tower installation, care must beexercised to get the antenna mast shimmed to theexact rotational center of the rotator. Thegeometry is such that a mast of 2.062" (2 1/16"[52 mm]) O.D. pipe will be exactly centered. Ifthe O.D. of your mast is less than this, you shouldshim out to these dimensions.

9. Return the rotator to the full CW "S"position. Mount the beam on the mastpointing South. The coaxial cable should belooped in such a manner that it will not foulor tangle when the beam turns around in acircle to the full 360° counterclockwiseposition.

OUTSIDE TOWER

6. If the rotator, top bushing and mast areproperly aligned, there should be unrestrictedrotation through 360°. If not, the rotator mayhave to be moved slightly on the flat plate. Ifa high quality bearing is used in the top ofthe tower (recommended), the shimmingprocedure must be done more carefully ascloser tolerances.are required. It is importantthat the rotator does not try to turn the masteccentrically with the top bushing or bearing.

7. Tighten the mounting bolts carefully - to ap-proximately 175 inch-pounds of torque.

8. Drill through the antenna mast and rotatorcasting, using a 5/16" drill. Locate the hole inthe clamp plate that is furnished. Insert thebolt through the clamp plate, mast, androtator and tighten all bolts to 150 inch-pounds. Refer to Figure 4.

Referring to Figures 5, 6, and 7, an outside toweror pole mount is made in the same manner exceptthat the rotator is fastened by four (4) bolts only(not six) to the Lower Mast Support, PN 5146710. Since the eccentricity of the rotator turning inreference to the tower is no longer important, theshimming procedure is not necessary. The four (4)screws must be torqued to the same specificationand the 8-wire cable securely fastened. The lowermast should be pinned with the 5/26"-18 x 4" boltas shown in Figure 6.

CAUTIONThe rotator is designed for vertical operation withthe bell shaped housing in the up position. Waterand other contamination will get into the motorunit if it's mounted horizontally or upside down.

PRELIMINARY CHECK ANDCALIBRATION

IMPORTANT

THERMAL PROTECTION: If the rotatorfails to turn after 4 or 5 minutes ofcontinuous operation, the thermal switch hascome into play. This protective device in thetransformer automatically shuts off power ifthe rotator is used continuously for too long.It will automatically reset after 10 minutes.

1. Turn the Control Unit Power "ON" withthe upper right "ON-OFF" switch. The metershould be illuminated and the needle shouldbe to the right.

2

3

4

When the control unit is turned "OFF", the meterneedle will fall to the left "S" position and returnto indicate the rotator position as soon as thecontrol unit is turned "ON' again. It will notdamage the unit to leave it turned "ON' for

Depress the brake lever (center) and hold. De-press the CCW lever (left) and operate therotator to its full CCW position. If the meterdoes not move from the right to the left handposition, press and release the "Calibrate"switch.

With the rotator in its full CCW position, ifthe meter is not at its full left position,carefully adjust the zero (CCW South)position with the screw directly under the

Meter Calibration Procedure: Operate therotator to its full clockwise position. Adjustthe calibration potentiometer until the meterindicates full scale to the right. The meter isnow calibrated. Do not adjust the calibrationpotentiometer when the rotator is in anyposition other than full clockwise.

NORMAL OPERATIONTo operate the rotator, it is necessary tounderstand the T2X Brake Release Lever and itsfunction. The brake lever (middle lever) on theControl Unit operates a brake wedge mechanismin the rotator which locks the rotator into positionmechanically. The rotator cannot turn unless thewedge is retracted by depressing the middle lever.The normal operation is as follows:

l. Retract the brake wedge by holding down the"Brake Release", middle lever. (Green lighton.) NOTE: The brake wedge will beretracted only while the Brake Release leveris held down.

2. Turn the rotator to the compass location bypushing down and releasing either the lefthand or the right hand lever.

Allow a few seconds for the rotator to coastdown. Then re-engage the brake wedge byreleasing the "Brake Release" (middle) lever.

OPERATING PRACTICEThe rotator has several mechanisms to protect itfrom misuse, but the following precautions areadvisable.

1. If you have a very large beam, the rotator canbe "nudged" to exactly the desired position byalternately working the left and right control,allowing it to coast down before the brakewedge is allowed to engage.

2. It is advisable not to run it full speed into theend of rotation.

3. Upon completion of turning, always allow therotator to coast down by keeping your fingeron the "Brake Release" after you havereleased the rotation lever. This procedurewill allow the rotator to stop before you re-engage the brake wedge. Observing thissequence prevents the rotator from stoppingsuddenly thus preventing undue stress on therotator, beam, and tower.

The motor has an internal brake which controlsthe coast down time and deceleration. Theinternal motor brake is usually strong enough toprevent pinwheeling during operation.

GROUNDINGThe tower, or other metal support device, must begrounded to an earth ground at its location. Useheavy copper cable looped so that if the towercomes down for any reason, there will beadequate slack to prevent the ground wire frombreaking. Use one or more 8 foot copper j acketedsteel stakes driven into the moist earth and fastenthe wire securely at the stake and at the tower.

5. Carefully remove the hex nuts on the meterstuds to free the printed circuit board. Slipthe P.C. Board off the studs and pull it downunder the chassis.

As mentioned in the "Cautions" portion, the steelchassis of the control box should be eithergrounded to a metal cold water pipe in the houseor back to the electric service entrance box wherethe power comes into the house. This normally isaccomplished with the wire of the 3-prong plugwhich then depends on the wall outlet beingadequately grounded back to the service entranceas to the utility ground. If there is any doubt, havethis checked by a licensed electrician.

SOUTH-CENTER METER SCALECONVERSIONThe stock Tailtwister Control Unit is shippedwith the meter scale installed for "North" centeroperation; ends of rotation are at the "South"position. Some geographic locations and/orpopular working areas may favor having themeter "South" center; ends of rotation are at the"North" position. We have provided theTailtwister with an interchangeable meter scale.

6. Loosen the meter retaining clips and removethe meter from the chassis.

7. Insert a small knife blade between the clearmeter cover and black housing at eithercorner of the top edge and gently pry thecover loose from that corner. Repeat for theother corner. The meter cover should pop

8. Carefully slip a knife blade under eachcorner of the lower edge of the white meterscale and twist slightly until the scale clearsthe two small indexing pins. Remove thescale and install the new one. Make sure thescale fits over the indexing pins and that it isflush and tight against the black housing.This will assure free movement of the

9. Reinstall the meter (remove the temporaryjumper), the P.C. Board and lamp hardware.Check for pinched, shorted end, oroverstressed wires.

10. Reinstall the top and bottom covers.We recommend the following

l. Disconnect the power cord.

2. Remove the 8-wire control cable, carefully la-beling each wire with its correspondingterminal number. This operation may beomitted if the control box can be worked oneasily without removing the leads.

11. Reconnect the 8-wire control cable in theexact sequence as they were removed.

If your beam was installed originally using theT2X with a "North" center scale, the antennamast must be loosened and repositioned. In orderfor the meter to indicate properly, the front ofyour beam must point "North" when the rotator isat the ends of rotation.

3. Remove the top and bottom covers. Recalibrate the meter.

4. Slip the lamp and holder off the lamp holderbracket. Loosen the hex nut on thetransformer that is holding the lamp holderbracket and swing the bracket clear of thewires leading to the printed circuit board.

NOTE: In the past the South Centered meterscale was on the reverse side of the factoryinstalled North Centered scale. The unit is nowprovided with a separate South Centered scale.This will help to avoid damage to the face of themeter scale during removal of the NorthCentered scale.

CAUTIONIt is good practice to use a short test leador jumper wire to short the meter studs

when it is not in the circuit.

TROUBLESHOOTING LACK OF POWERGENERAL DESCRIPTIONMost operational difficulties with rotators aretraceable to broken, shorted or grounded wiresusually at the rotor connections. Time spent incutting the leads to exact lengths, tinning, andclamping to prevent strain on the control cable,will pay dividends.

CAUTION

:;This unit has been thoroughly tested and;;::cycled before shipment. Follow the;::;connector wiring carefully between Rotator;:::and Control Box. Incorrect wiring will burn::::out the rotator potentiometer and void the:::;warranty.::Be sure Rotator and Control Units are:::;compatible. Do not intermix models with::•;different operating voltages. This results in::::sluggish or non-operating performance,;:::burned out motors, overheated transformers:::;and burned out rotator potentiometer, etc. ~:

If the antenna rotation is slow or sluggish or hardto start, check for proper voltages. If the voltagesare correct, the 130-156 MFD motor startcapacitor could be at fault. It is recommended thata new capacitor be tried before any other action istaken. Also, check proper wire size per Table 1,page 4.If the electrical circuit is okay, then check formechanical binding. Pay particular attention tobearings and alignment of the mast of an insidetower mount.

If the temperature is less than -300 F (-340 C),the rotator will be very sluggish and hard to start.This is normal. Hold down on the rotation switchuntil movement is seen on the meter.

If the capacitor is good, the temperature is wellabove -30°F, and there is no mechanical bindingabove the rotor, the rotor may not be receivingthe proper voltage levels to achieve maximumtorque. Check the cable resistances, and wiresizes. For cable runs over 300', move the motorcapacitor to the tower.

MECHANICAL PLAY

Frequently the slight motion of the antenna arrayin gusts of wind is due more to the natural flexingof the elements and mast than it is due to actualplay in the rotator mechanism. A slight amount of"play" is built into the rotator to avoid bindingdue to environmental changes.

ANTENNA ROTATES IN HEAVY WIND

This is usually a matter of the mast slipping inthe, support. For large arrays, it is often necessaryto drill a 5/16" hole through the clamping plate,mast and mast supports and pin them togetherwith the stainless steel bolt supplied.

IMPROPER METER INDICATION

The brake and motor operate independently of theindicating system. If the pilot light burns at properbrilliancy, the instrument transformer is okay andthe output is not shorted. Check the 1/8 ampmeter circuit fuse with the ohmmeter. Check forabout 13 VDC across Terminals No. 3 and No. 7with the switch operated. If the proper voltage isnot obtained, check the individual components inthe meter circuit. If the 13 VDC is present, checkfor 500 ohms across rotator leads No. 3 and No.7. If 500 ohms is present from No. 3 and No. 7,see if the readings from No. 3 to ground and No.7 to ground total 500 ohms.

If "slipping" or "turning" is suspected, return therotator to the end of rotation and visually checkto be sure that the antenna is in the original stoplocation as installed.

NOTE: An intermittent condition in anycomponent in the rectifier or meter circuits withinthe control box, as well as in the cable orpotentiometer circuit in the rotator itself cancause meter fluctuation or error. Possible cause ofsuch trouble may be localized by placing a testDC meter across Terminals No. 1 and No. 3 orNo. 1 and No. 7 comparing the action of the testmeter with the panel meter.

NO ROTATION - INDICATION OKEither the thermal cut-out in the powertransformer has opened or there is actually troublein the motor circuit. After allowing time for thethermal cut-out to restore service, proceed to"Checking the Control Unit" and "Checking theRotator from the Ground".

GROUND WIRESGround on cable leads can burn out either the linefuse or the small fuse in the meter circuit. If leadNo. 3 or lead No. 7 is grounded, it shorts out partof the potentiometer so that as rotation progressesto the other end, the full DC voltage is appliedacross a decreasing portion until current becomesso high that the potentiometer burns out. Notealso that any grounds may put an overload on thepower transformer which could cause the linefuse to blow or overload the rectifier circuit sothat the 1/8 amp fuse blows.

HELPFUL SUGGESTIONS

Be sure to check your rotator cable for shorting,open circuits, incorrect wiring, intermittent con-nections, shorted terminals, rodent damage, andmast support or thrust bearing binding.

2. Resistances with Unit Not Plugged In.Disconnect the AC power source and discon-nect the 8-wire control cable.

The control box can be checked withoutremoving the cover by using a volt-ohmmeterto check values across terminals. Resistanceacross Terminals 1 and 2 should read 4 ohms.Read same value across Terminals 1 through5 with clockwise switch lever (right hand) de-pressed and across Terminals 1 through 6with counterclockwise switch lever (left hand)depressed. Resistance across input line cordwith "ON-OFF" switch in the "ON" positionand the brake lever depressed should read 3.8ohms

CHECKING THE ROTATOR FROM THEGROUNDYou may possibly avoid bringing the rotatordown by making electrical checks from thecontrol box position. This is done bydisconnecting the eight wire control cable fromthe control unit. From the schematic diagram, it isapparent that the resistance of the lead wires willbe added to the resistance of the motor windingsand potentiometer strip in making the resistancechecks as shown in Table 2.

CHECKING THE CONTROL UNIT

1. Voltages with Unit Plugged In.To check the control unit, plug the line cord intoAC power. With no connections to the terminals,turn the "ON-OFF" switch to the "ON" position,the meter light will illuminate. The meter needlewill remain on the left hand "S".

.Terminals 1 and 2 should show 30 volts AC(approximately) when the brake level is de-pressed.

Terminals 1 and 5 should show 30 volts ACwith brake release lever depressed and CWlever depressed.

Table 2

Terminals 1 and 6 -should show 30 volts ACwith brake release lever depressed and CWlever depressed.

Terminals 3 and 7 should showapproximately 13 VDC.

4. Check cable between leads. Static lightningcharges or direct hits will cause carbon arcsin control cable at numerous spots along thecable that cannot be seen. This resistive pathwill break down with voltage applied torotator. (Replace cable.)

5. Check both control and rotator connectors forshorts.

6. Rotation in one direction usually indicates aloose or broken cable wire, bad relay, and badsensing transistors in some units.

Be sure cable is of proper size for length used.Refer to Table l.

Substitute a 3 foot piece of new rotator cableto bench test unit. Proper operation willindicate a defective rotator cable on the mastor tower, or a cable not large enough to createproper turning torque.

9 Low line voltage and cold weather will slowrotation. Using an extra long or small wireextension cord can lower line voltage.
