1. If the victim is not responsive follow the A-B-Cs ofbasic life support. Place victim face-up on a flat hardsurface. Three critical areas (Airway, Breathing, andCirculation) need immediate attention:

WARNINGBITE HAZARD

USE CAUTION WHEN PLACINGFINGERS IN VICTIMS MOUTH, MUSCLESPASMS CAN CAUSE THE MOUTH TOCLOSE WITH FORCE SUFFICIENT TOSEVER YOUR FINGERS. FAILURE TOCOMPLY MAY RESULT IN LOSS OFFINGERS.

a. Airway - If victim is unconscious, open airwayby lifting up the neck while pushing back on thevictims forehead. Refer to Figure 1A. Clearmouth of obstructions and observe for breathing.

WARNINGRESCUER KEEP CALM

EXCESSIVELY DEEP AND RAPIDBREATHING BY THE RESCUER MAYRESULT IN RESCUER BECOMINGFAINT, TO TINGLE, AND EVEN LOSECONSCIOUSNESS. BREATHING SHOULDBE NORMAL IN RATE WITH ONLYMODERATE INCREASE IN VOLUME.FAILURE TO COMPLY MAY RESULT INRESCUE BEING PREMATURELYSTOPPED DUE TO FATIGUE.

b. Breathing - If victim is not breathing beginartificial breathing. Tilt head, pinch nostrils,make airtight seal with your mouth, and blow 4quick full breaths into the victims lungs. Refer toFigure lB.

c. Circulation - If victim does not have a pulse, seeFigure 1C, begin artificial circulation. Depresssternum 1Y2 to 2 inches then release. Refer toFigures ID and IE. WITH ONE rescuer:Perform 15 compressions and 2 quick breaths atthe rate of 80 per minute. WITH TWO rescuers:Perform 5 compressions and 1 breath at the rateof 60 per minute.

IX MAJOR EMPLACEMENT ANDMAINTENANCE HAZARDS

The precautions given in 1 and 2 below must be observed toprevent injury or death to personnel:

1. Installation and assembly hazards associated with theequipment are as follows:

a. After performing maintenance ensure the doorsand covers are installed prior to attempting toreturn the equipment to service.

b. On all electrolytic capacitors, make sure terminalpolarity markings [positive (+) and negative (-)]are observed when connecting capacitors to ± dcbuses.

2. While performing maintenance on the equipment,observe the following precautions:

SAFETY SUMMARY

2. Electrostatic handling of MOS devices is of primeimportance. Stati~ electricity is always present in anywork environment. It is generated when ever twodifferent materials are rubbed together. A personwalking across the floor can generate a charge ofthousands of volts. A person working at a bench,sliding around on a stool, or rubbing his arms on thework bench can develop a high static potential. Forpreventing damage to devices due to ESD, use thefollowing precautions:

a. Table tops or work areas should be covered withgrounded conductive tops. Test areas shouldhave conductive floor mats.

b. Tools and test equipment used in protected workareas shall be properly grounded. Ensure thatsoldering-iron tips are grounded. If plastichandled tools must be used, they shall be treatedwith a topical antistat.

STATIC SENSITIVE DEVICES

b. When performing maintenance on the equipmentmake sure all ac power to the unit is removed.

X

a. Maintenance of equipment shall not beperformed when thunderstorms and lightning areimminent or in progress.

c.

d.

Devices, or circuit cards with devices, should notbe inserted into or removed from circuits withthe power on because transient voltages maycause permanent damage.

Use a conductive wrist strap when removing acircuit card containing MaS/CMOS devicesfrom a card cage or when removing a devicefrom a circuit card.

There are some circuits throughout the equipment usingmetal-oxide-semiconductor (MaS) and complementaryMaS (CMOS) integrated circuits. This requires stringentattention to handling techniques due to the sensitivity tostatic electricity. The following paragraphs outline theprocedures to use when handling MaS or CMOS devices.

1. Electrostatic discharge hazards in MaS/CMOSdevices are prevalent. Such damage can be producedby Electrostatic Discharge (ESD) due to improperhandling or installation. All MaS/CMOS devices aresusceptible to damage by the discharge of electrostaticenergy between any two pins. This sensitivity to staticcharge is due to the fact that gate input capacitance (5picofarads typical) in parallel with an extremely highinput resistance (1012 ohms typical) lends itself to ahigh input impedance and hence readily builds up theelectrostatic charges.

3.

e. The devices are to be stored or transported instatic shielding bags, anti-static rails, orconductive foam.

ESD grounding is critical to safe handling of ESDsensitive devices. Earth ground rods for ESDprotection shall be solid copper or copper jacketedsteel and shall be driven six to eight feet into the earthbeyond the work area floor slab with approximatelysix inches exposed for making connection. Dry soilconditions may require a copper sulfate drip. Electricalgrounds shall be isolated from static grounds.

Water pipes offer convenient grounds; however, theymay not be connected to earth ground. Thesetechniques are for minimizing the difference ofpotential between separate grounds, and not forreducing the ohmic resistance to earth.

INSTALLATION

2-1. PRE-INSTALLATION INFORMATION

The transmitter requires three phase 200 to 250 volts, 50 or60 Hz, AC primary power of either Wye or closed Deltaconfiguration. Line-to-line balance must be within fivepercent both for voltage and phase.

Refer to Figure 2-1 for location of air ports, wire ports, andcabinet dimensions. The transmitter should be located toallow access to front and rear.

2-1.1 AC Power.

Figure 2-1 shows the location of the openings in the top andfloor of the transmitter that can be used to bring the powercables into the transmitter. Power cables may be broughtthrough either a two-inch (5 em) knockout in the top of thecabinet or through a two-inch round opening in the floor ofthe transmitter. The size of the power wiring is determinedby local electrical code and good engineering practice. In nocase should the wiring be smaller than number #1/0 AWGwire where the wire length is up to 100 feet (31 m). Thedisconnect fuses should be 150 ampere slo-blow. Thetransmitter has a 150 ampere primary power disconnectbreaker.

AC line transient suppressors are suggested for the primaryI lines. For recommendation of suppressors, call CE Field

Service.

2-1.2 RF Output Power.

The RF output power termination is a 3-1/8" EIA flangelocated at the top of the directional coupler just above thePA cavity.

2-1.3 Transmitter Cooling.

In many locations ventilating a building is preferred over airconditioning. Air conditioning equipment is mechanical andcan break down, is initially expensive, and is expensive tomaintain and operate. The 816R-2C transmitter can operatein a room environment where temperatures can be as low as-4 0 F to as high as 122 0 F. There are several different waysto ventilate a room that will be discussed in followingparagraphs. Refer to Figure 2-2 for nominal heat balancevalues.

Change 5

2-1.3.1 Exhaust Fans. There are times when exhaust fansare the best means of ventilating a transmitter space. If theroom is large and it is not possible to locate the transmitter

near an outside wall, exhaust fans may be the onlyreasonable way to ventilate a room. It is better in thissituation to vent the transmitter directly to the room orthrough a short duct to the attic and use exhaust fans in theroom or the attic. It is important to arrange the transmitterexhaust so that there is no chance of recirculation of exhaustair back into the transmitter.

There are many good ways to make an installation utilizingexhaust fans and one method will be described here. If theroom has a high ceiling (more than 10 feet), install a dropceiling about eight feet from the floor. Vent the transmitterexhaust directly into the space above the drop ceiling. Letthe transmitter take air from the room. At the four corners ofthe drop ceiling install air registers that will allow air fromthe room to escape into the area above the drop ceiling.Install an exhaust fan that will evacuate the area above thedrop ceiling. This method will not have the exhaust fancompeting with the transmitter fan and blower, will preventrecirculation (providing exhaust fan does not fail), and \villprovide ventilation for the transmitter space. There arevariations of this scheme that will allow recirculation(controlled by a thermostat) in the winter to heat thetransmitter space.

Although exhaust fans and blowers are the most commonmethod ofventilating transmitter spaces they are not the bestin some cases. The three cautions listed below are somereasons for choosing another method when there is a choice.

1. An exhaust fan allows unfiltered air into the transmitterby expelling air from the room or building and pullingair into the room through any and all openings in theroom. The transmitter space should be as clean and dustfree as possible. It is not likely that the transmitter spacecan be air tight except for the filtered air intake. Theunfiltered openings will allow dust and dirt into thetransmitter space.

2. An exhaust fan results in dead air spaces since it doesnot "stir" the air in a room which makes "dead airspaces" possible. There is usually only one intended airinlet to a transmitter space and the air movement is fromthat inlet directly to the exhaust fan.

2-1

INSTALLATION

2-1.3.1 Exhaust Fans. - Continued

3. In installations where the transmitter is ducted to theoutside and takes air from the room, the exhaust fan iscompeting with the transmitter cabinet fan and cavityblower for air through the same room air inlet. In thissituation, the greater capacity of the exhaust fan willreduce the transmitter cooling if the room air inlet is notlarge in size. Where exhaust fans or blowers are used,the room air intake must be large enough so that theroom in not under negative pressure. Negative pressureat the transmitter air inlet has the same detrimental effectas back pressure of the same amount at the transmitterair exhaust.

2-1.3.2 Positive Pressure. Positive pressure ventilationforces air into the room and the air escapes throughopenings in the room. The air may be forced into the roomwith propeller type fans or with centrifugal blo\vers.Propeller type fans move more air with smaller motors thanwill centrifugal blowers. A 30 or 36 inch fan is quiet andcan move more than 3000 cfm of air into a room and useonly a 1/4HP motor. Some of the advantages of positivepressure ventilation are:

1. All the air entering the room comes through one openingwhich can be easily filtered. When doors or windows areopened, air moves out through the opening.

2. A fan blowing air into a room will "stir" the room airreducing the risk of dead air space. Deflectors at the fancan be used to direct air into areas that might nototherwise have moving air.

3. All fans aid each other. The fan that is forcing air into aroom is aiding the transmitter fans in cooling thetransmitter. All the fans, the room fan, the transmittercabinet fan, and the power amplifier cavity blower aremoving the air in the same direction through thetransmitter.

4. Like the exhaust system, the pressure system will alsoventilate the room. The transmitter will exhaust about500 cu-ft/min. of air to the outside. If the room fan iscapable of moving three or four thousand cu- ft/min. ofair into the room, another opening in the room must beprovided for room ventilation.

An example of positive room ventilation will be describedhere. This is intended only as an example and can bemodified to meet your particular requirements.

Locate the left end or the rear of the transmitter near anoutside wall in order to keep the exhaust ductwork as shortas possible. Position the transmitter so that the exhaust ductwill not interfere with the coaxial RF output line. If the total

2-2

816R-2C

duct run is eight feet or less and there are no more than twoelbows, 16 inch round or the equivalent square duct can beconnected directly over the transmitter exhaust output usingsheet metal screws. (Dse care when drilling holes for sheetmetal screws so as to avoid metal shavings falling into thetransmitter.) The duct will have to be turned down at theoutside to prevent rain and snow from getting into it. A belltype transition should be used at the end of the duct toreduce turbulence.

The duct above the transmitter will have two dampers andan opening to the room. The dampers will be motorcontrolled and mechanically linked together so that theopening to the room will be closed off at the same time thatthe air from the transmitter will be directed to the outside.With the dampers in the second position, the air from thetransmitter will be directed to the room instead of outside.The mechanical linkage is necessary to prevent thepossibility of both dampers being closed at the same time.This arrangement will allow the transmitter to exhaust to theoutside in the summer and recirculate to the inside in thew·inter.

A fan that has enough capacity to change the room air atleast once each minute is installed in the wall. This fan pullsfiltered air into the room through motor controlled louvers.A 3000 cfm fan will change the air once a minute in a15X20 foot room having a 10 foot ceiling.

An opening with motor controlled louvers is provided in thesame wall where the fan is mounted. The reason for intakefan and room air outlet being on the same wall is tominimize the effects of wind on the ventilation system. Ifboth inlet and outlet are on the same wall, the effects ofwind, regardless of direction, is neutralized since the windpressure is the same on both. The transmitter air exhaustshould be on this wall also. The transmitter exhaust shouldnot be positioned so that there is a risk of recirculation.

With motor control on inlet and outlet louvers andtransmitter duct dampers, it is possible to control theoperation of louvers, dampers, and the ventilation fan withthermostats. Set the thermostats, based on environmentalconditions, to maintain the required equipment operatingtemperature at all times. Three conditions are describedbelo\v that will give different results:

1. A condition of maximum ventilation and cooling willresult during the hottest periods. The transmitter will beducted to the outside and the intake fan will be running.The outlet wall louvers will also be opened to permitroom ventilation.

2. A condition of minimum ventilation will exist at timeswhen it is not necessary to run the room intake fan, butthe transmitter should be vented to the outside. Underthese conditions the transmitter exhaust dampers willdirect the transmitter exhaust to the outside, the outletwall louvers will be closed, the fan will be off, and theinlet fan louvers will be open to allow fresh filtered airinto the room and transmitter.

3. A condition of recirculation for heating will exist duringcold periods. The transmitter exhaust dampers will bepositioned to allow transmitter exhaust air into the roomand all outside outlets and inlets will be closed.

The system described will require two heating typethermostats and control relays. One will be set toapproximately 65 ° F and the second will be set toapproximately 85° F.

At temperatures above 85 ° F, the first condition describedabove will exist.

For temperatures between 65 ° F and 85 ° F the secondcondition described above will exist.

For temperatures below 65 ° F the third condition describedabove will exist.

The thermostats should be mounted approximately sevenfeet off the floor and in an area of the room where thetemperature is not influenced by heat radiated by thetransmitter or by direct air flow from the room intake fan.

The transmitter space should also be provided with athermostatically controlled heater that can be set toapproximately 50° F. This will provide heat duringmaintenance periods or during times that the transmitter isoff-the-air, if not a 24 hour operation.

2-1.3.3 Transmitter Exhaust Duct. Regardless which airsystem is used, careful consideration must be given tolocation of transmitter, air intake, and air outlet vent whenusing outside air for cooling room and equipment. First,consider where to place the transmitter. The transmitter

2-6

816R-2C

exhaust will be vented to the outside and transmitter willtake air from the room. Since the transmitter will exhaust tothe outside, the exhaust vent on the transmitter should beplaced as close as possible to an outside wall. Although it ishighly undesirable, it is possible to exhaust through the roofbut extreme care must be used to weatherproof and leakproof the ductwork above the transmitter. Since water thatmay leak at the ductwork will likely get into the transmitter,it is absolutely necessary to check for leak proofing often. Inany case the ducts must be kept as short as possible tominimize back pressure at the transmitter outlet. Rememberthat elbows, vent caps, and hoods all add extra resistance toair flow through the transmitter. In most installations, thetransmitter can be placed so that no more than eight feet ofexhaust duct is needed. If this is possible, 16 inch roundduct or the equivalent rectangular duct will be acceptable.Do not use more than two elbows. It is not a good practiceto connect more than one transmitter to the same exhaustduct. Let each transmitter have its own individual exhaustduct.

Where possible use large ductwork instead of duct fans.Duct fans may be required if the duct run is long but ductfans increase air resistance if they fail; therefore, somemethod of monitoring and interlocking to the transmittermust be used if there is no alternative to the use of duct fans.

2-2. UNPACKING AND INSPECTING

2-2.1 Domestic Shipments.

The uncrated transmitter cabinet is shipped on a shippingskid. The transmitter is attached to the skid by shippingbands. Inspect for loose screws and fasteners. Ensure allcontrols operate freely. Examine the cabinet for dents orscratches. Ensure cable and wiring connections are tight andsituated clear of obstructions.

If any item is freight damaged, the customer should acceptthe equipment, note the damage on the shipping documentsand immediately file a freight claim. All boxes and packingmaterial should be retained for the freight inspector. Refusalto accept delivery of damaged equipment removes theevidence and makes freight damage reimbursementcomplicated or impossible.

CAUTION

ENSURE THAT THE TRANSMISSION LINEAND ANTENNA PRESENT A 50 OHMIMPEDANCE AND A VSWR NOT GREATERTHAN 2:1 TO THE TRANSMITTER AT THEOPERATING FREQUENCY. DAMAGE MAYRESULT FROM AN IMPROPER IMPEDANCEMATCH BETWEEN THE TRANSMITTERAND THE RF SWITCH, TEST LOAD, ORTRANSMISSION LINE.

8. Connect the customer-supplied, 50-ohm transmissionline to the RF output connector mounted on top of thetransmitter cabinet.

CAUTION

FOR 60 HZ OPERATION ONLY, THETRANSFORMER PRIMARY TAPS MUSTNOT BE SET MORE THAN TWO TAPSLOWER THAN THE HIGHEST LINEVOLTAGE EXPECTED. FOR EXAMPLE, IFLINE VOLTAGE IS 245 VOLTS, THE SCREENTRANSFORMER PRIMARY TAPS CAN BESET TO THE 230, 240, OR 250 VOLT TAPS. IFLINE VOLTAGE IS 240 VOLTS, THE SCREENTRANSFORMER COULD BE SET TO THE 220VOLT TAPS IF NECESSARY TO INCREASETRANSMITTER POWER. TRANSFORMERTAPS SHALL NOT BE SET TO LOWER TAPSTHAN THE HIGHEST EXPECTED LINEVOLTAGE WHERE 50 HZ PRIMARY POWERSOURCE IS USED. FAILURE TO COMPLYMAY RESULT IN DAMAGE TO EQUIPMENT.

INSTALLATION

9. The transmitter is shipped with all transformers on thehighest voltage taps unless specific instructions aregiven regarding source line voltage. This is done toprevent damage where line voltage may be higher thantransformers are tapped for and power is appliedwithout changing taps.

The broad range of allowable voltage sources (200 to250 volts) is made possible by the availability ofdifferent primary tap connections of power transformersT1, T2, T3, and A 1OTl. Figures 2-6 and 2-7, and Table2-1 show the details of the proper primary lineconnections for various source line voltages. Figures 2-8shows the proper T2 secondary line connections forvarious input line voltages.

In addition to the primary taps, the screen transfonner(T2) has three sets of secondary taps. These secondarytaps are identified as 1000/0, 850/0, and 700/0. The DCscreen voltage will be 800 volts when the primary tapsmatch the source line voltage and the secondary leadsare connected to the 1000/0 taps. For example if thesecondary leads are moved to the 700/0 taps the DCscreen voltage will be lowered to 560 volts.

20. Slightly adjust the PA LOADING and PA TUNINGcontrols until maximum power output is displayed onthe POWER OUTPUT meter.

21. As the transmitter warms up, the IPA reflected powerwill rise. Re-tune the PA GRID TUNING as needed tokeep the reflected power below 75 watts (final value isless than 20 watts). Once the IPA reflected powerappears stabilized, repeat Steps 19 & 20. The finalsetting should be established after the transmitter hasbeen on for at least 30 minutes. Do not re-tune the gridafter the final setting has been established.

NOTE

Operating parameters will become stable within15-20 minutes. All fine tuning and recording ofoperating parameters should be performed onlyafter the transmitter has stabilized.

22. RAISE or LOWER the POWER ADJUST control untilthe POWER OUTPUT meter displays the station'sauthorized power level. If specified by the customer,the meter was calibrated at the factory to indicate 100%at this power.

23. Compare meter readings with those listed in the factorytest data located at the back of this manual. If additionaltuning or transformer tap adjustment is required, referto the adjustment procedures listed in Paragraph 5-7.

24. Set POWER CONTROL switch to AUTOMATIC.Adjust the power monitor/control card A2A6R8,located in the card cage, for 1000/0 output power ifnecessary.

25. PA TUNING AND LOADING (For best efficiency).There is not likely to be a plate current dip within thenormal range of tuning control. There are, however,three indicators to be observed for proper PA TUNE.Power output and screen current will be maximum. PAplate current will change as the tuning is changed. Platecurrent will increase when the tuning control is held inthe raise position. When the shorting plane ispositioned correctly, the PA screen current and poweroutput will go through a peak. Refer to Figure 3-6 foran indication of what to expect as the tuning control isrun through its total mechanical range, from one limitto the other. Notice that power output is the same atpoint A and point B, but that plate current is greater atpoint B. The proper tuning point is at point A whichresults in maximum output and also the least amount of

OPERATION

plate current (not plate current dip). The loading controlis adjusted for maximum RF output. PA screen currentdecreases when loading is raised and increases whenloading is lowered. Normally, screen current is between300 - 600 rnA. The screen current is dependent uponloading, power output requirements, plate and screenvoltage, and individual tube characteristics. When thePA tube is replaced, screen voltage may have to bechanged in order to obtain the desired power output.

THEORY OF OPERATION


following paragraphs. Refer to Figure 4-3 and Schematic195125.

The FM Transmitter, 816R-2C, operates in the 88 to l08MHz range at a maximum rated RF output of21.5 kW. ACEC 802B solid state, wideband, FM exciter providesexcitation. The transmitter is equipped with circuits thatmaintain constant power output and protect the transmitterfrom overload conditions. A control panel providescomplete transmitter metering and tuning controls. Refer tothe overall schematic diagrams for detailed circuitinformation.

4-2. FUNCTIONAL DESCRIPTION

Refer to Figure 4-1, an input signal (monaural, stereocomposite, or SCA is supplied to the exciter. The exciter'sRF output drives a two stage power amplifier. The firststage, the intermediate power amplifier (IPA), raises theoutput to a level of 500 Watts. The last stage, the RF poweramplifier, raises the output to the transmitter's rated poweroutput. The power amplifier is followed by a low pass filterand a directional coupler which is connected to the station'santenna system. A dc sample of the forward power from thedirectional coupler (DC l) is monitored by the auto powercontrol circuit. If a change in output power is detected, asignal is sent to the power control board that increases ordecreases the plate and screen power supply input voltage tocompensate. A sample of the reflected power is alsomonitored by the power control circuits. If an excessiveamount of reflected power is detected, the control circuits

I remove the transmitter plate voltage. The 24 Vdc powersupply provides power for the control circuits.

4-3. RF CIRCUITS

Refer to Figure 4-2 for a simplified diagram of the RF drivepath. The drive path consists of the exciter A4, intermediatepower amplifier (IPA) A3ARl with its directional couplerA3DCI, coupling capacitor AI2CI, and power amplifier(PA) VI with its grid tuning components A12C3, A12LlL3, and A12C2. IPA metering and 3-phase power supplycontrol circuits are also shown in Figures 4-2 and 4-4.

4-3.1 Exciter, A4.

Refer to the 802B instruction manual, principles ofoperation.

4-3.2 IPA, A3.

The IPA consists of a Metering Assembly, StatusAssembly, and Amplifier Assembly as described in the

Change 5

4-3.2.1 Metering Card, A3A 1.

The IPA Metering Card permits measurement andcalibration of IPA supply voltage, current, forward RFpower, and reflected RF power. The metering circuitry cardis powered from the 50 Vdc IPA supply through VRIproviding 12 Vdc. Switch SI-A, -B, -C and -D selectswhich signal the external meter is monitoring. ResistorsR31 and R32 adjust the voltage sample. Op-amp U2-B andresistor R27 control the current sample. Op-amp U1-B andresistor R23 control the forward power sample. Op-ampU2-A and resistor R14 control the reflected power sample.Comparator U1-A and R22 set the VSWR trip level.Transistors Ql drives the VSWR LED while Q2 providesan excess-VSWR status output. Refer to Block DiagramFigure 4-3 and Schematic 195080 Figure 7-8.

4-3.2.2 Status Card, A3A2

The Status Card is a passive circuit consisting ot two LEDsdriven by signals from the Metering Card A3A 1. TheLEDs indicate power ON and high VSWR. Refer to BlockDiagram Figure 4-3 and Schematic 189626 Figure 7-9.

4-3.2.3 Amplifier Assembly, A3A3. The AmplifierAssembly consist of an RF splitter, two RF amplifiers, anRF combiner, and a 50 Vdc power supply. The splitterconsists of two quarter wave lengths 75 ohm line and a 100ohm balancing resistor. The input to the splitter, from theexciter, is equally divided and impedance transformed to theinput of each of the two RF amplifiers. Each amplifier hasa power gain of approximately 16 dB and the outputs ofboth amplifiers are summed together by the con1biner toprovide an output of 500-600 watts. The combiner is thereverse of the splitter and consists of the same parts, onlywith greater power handling capability. The IPA isfollowed by directional coupler A3DC 1. The couplerdrives the IPA RF power meter and a VSWR warningindicator. The IPA receives its dc power from a 50 Vdcsupply, part of which is on the AS assembly. The AmplifierModules, A3AI and A3A2, consist of two circuit cardassemblies mounted on a common heat sink, refer toSchematic 189397. The two circuit card assemblies are RFAmplifier and Control Assembly.

4-1

THEORY OF OPERATION

4-3.2.3.1 RF Amplifier. The RF Amplifiers use a systemof lumped coaxial lines to match the drain-to-drainimpedance of 12.5 Ohms, balanced, to 50 Ohms, balanced.See Schematic 189214. Transmission lines TL101 andTL 102, which have a characteristic impedance of 25 Ohms,are seriesed at their output connection to TL 103 (for 50Ohms) and are paralleled at their input connection to theamplifier transistor, Ql, to present a 12.5 Ohm impedance.The balanced 50 Ohm output impedance at the junction ofTL 1Oland 102 must be converted to a unbalanced outputsignal for coaxial transmission. This is accomplished byTL 103. The length of this line is just long enough topresent a large impedance to the unbalance current in itsshield. This type of current balun results is excellentbalance to the transistor drains.

The amplifier module is untuned. The operation of thetransformers and the balun serve to limit the operating rangeto 80-120 MHz. The input of the amplifier is similarlybroadband. Capacitor C 101 is adjusted to insure thatvariations in such things as the gate capacity of theamplifier FET transistor and the leakage reactance of theinput transformer are balanced out to provide a good inputmatch to drive the Splitter over the operating range.

The output transistors of the PA Modules operate insaturated push-pull, Class BC, with an operating angle ofapproximately 150 degrees and a drive level, at full output,of up to 20 Watts. This results in a conversion efficiency inexcess of 750/0. The bias adjustment for the RF transistor,R220, is adjusted to give an operating bias of + 1.5 to 3.5Vdc. This bias adjustment also serves as a gain control.During final testing, slight adjustment of the bias control ismade to insure that the gain of both RF amplifiers are equal.

There is an optimum drive level for the PA Modules. Asthe amplifiers are under-driven, they go into a linear modeand conversion efficiency drops. Over driving theamplifiers results in excessive harmonic content at theamplifier drains which also causes a drop in conversionefficiency. Drive level is adjusted by varying the exciteroutput to obtain the desired drive power to the finalamplifier tube.

4-3.2.3.2 Control Assembly. The Amplifier ModuleControl Assembly is an on-board protection system toprotect the module from over-current and over-temperature.The Schematic Diagram, 189211, shows that the operatingvolt..ge for the protection circuitry, +15 Vdc, can be derivedfrom either the +24 Vdc Control Power Supply of thetransmitter or from the +50 Vdc supply through theisolation diodes, CR201 and CR202. Voltage for the RF

4-2

816R-2C

transistor flows through the over-current shunt, R209, andthe ON/OFF switch, Q203. Switching transistor Q203 iseither ON or OFF in this circuit. The voltage on either sideof the over-current shunt, R209, is reduced to +8 Vdc by thebridge circuit. As the current flow, the over-current shuntcauses a voltage drop, 0.5 Vdc when the current is 10amperes. The voltage differential is amplified by a bufferamplifier so that the output of buffer, U201 A is 6.4 Vdc,when the current through the amplifier is 10 amperes. Thisvoltage appears on Jl-2 and is used to monitor the current ineach module. This current-related voltage is also bufferedand divided and feeds the non-inverting input ofU201B. Apreset reference voltage of +4 Vdc is applied to theinverting input ofU20 lB. When the current through theamplifier exceeds 12.5 amperes, the output ofU201 goeshigh and fires the SCR, Q202. This, in turn, pulls the baseof the switch driver, Q201 low. This turns Q201 ON whichcauses the gate voltage of Q203 to rise to input voltagevalue. Unless the gate ofQ201 is low, the switch turns OFFand removes voltage from the amplifier. Each RF Module isalso protected with a 12 ampere fast-acting fuse.

Over-temperature operation is detected by the thermalswitch, S1, on the amplifier assembly. This switch ismounted in contact with heat sink close to the attachmentpoint of the amplifier transistor. Closure of the switch dueto over-temperature (80 degrees C.) causes current to flowin the opto-isolator U202. This causes the voltage across theopto-isolator output transistor to fall to zero. Again, theswitch, Q203 opens and removes voltage from theamplifier. Operation of the thermal switch is throughresistor R223.

4-3.3 RF Power Amplifier, A12.

The RF power amplifier is driven by the IPA through amatching network consisting of the COUPLING control(C1), the PA GRID TUNE control (C2), and L1, 2, 3 (SeeFigure 4-2). Capacitor C3 and resistor R1 swamps thepower amplifier grid circuit and provide a more uniformimpedance to the IPA under varying drive conditions.Inductor L14 and the distributed capacity of resistor R75couple R75 to the cavity, forming a suppressor thatdampens the higher order cavity resonances that can occurnear the third harmonic of the output frequency. Cathodetuning (or peaking) capacitor C39 improves the bypassaction at the operating frequency. Inductor L5 is the poweramplifier grid bias feed choke.

The power amplifier is a plate tuned 4CX15,000.A. tube thatis operated as Class C. The tube screen is grounded and the

Change 3

816R-2C

cathode is placed 750 Volts (nominal) below ground toprovide screen voltage, as shown in Figure 4-5. A fixed biasfrom the power amplifier bias power supply is applied to thecontrol grid through terminal A5E12, resistor A5R13, andterminal A5E 13. When an input signal is present, gridcurrent flows and develops grid leak bias across resistorsR35 and R36. The increased negative potential on the gridcauses the diode in the power amplifier bias supply toreverse bias, preventing grid current flow through thesupply. Hall effect probe A5Z1 monitors the amount of gridcurrent for control panel metering.

The power amplifier plate circuit is coarse-tuned from 88 to108 MHz by resonating adjustable coaxial resonators,Figure 4-6. The resonators are in the area between the tubeshelf and the sliding shorting plane. Two motor-drivencapacitors permit more precise tuning (capacitor C51) andloading (capacitor C50). RAISE or LOWER switches S10or SII (PA TUNING) and S12 or S13 (PA LOADING) oncontrol panel A 1AI, control the capacitor drive motors. Thedc blocking capacitor C2 is located between the top ofpower amplifier tube and input to the air chimney. Figure4-7 shows the electrical equivalence of the plate tuningcircuit.

4-3.4 Low-Pass Filter, A7.

Low Pass filter A7 (Figures 6-1, sheet 2) consists of twocoaxial filters in tandem. The first filter has a cutofffrequency of 130 MHz, while the second has a cutofffrequency of300 MHz.

4-3.5 Directional Coupler, DC I.

The directional coupler provides a proportional dc voltageto both the forward and reflected circuits of A2A6. Theoutput of each is then routed to, and can be displayed on,the Forwardl Reflected Meter (AIM4).

4-4.1 General.

Refer to transmitter schematic 189632 for the followingdiscussion. There are five separate power supplies in thetransmitter. Three of the five, the plate, screen and poweramplifier bias power supplies provide voltages to the poweramplifier. The Driver supply, furnishes voltage to the IPAstage. The 24 Vdc power supply provides power to the Icontrol circuits.

4-4.2 24 Vdc Power Supply, PIO A10. I

The 24 Vdc supply is a fully self-contained power supply. IA parts list and schematic diagram is included in thismanual.

4-4.3 Power Amplifier Bias Power Supply, PIO Al O.

The power amplifier bias power supply provides the poweramplifier with fixed grid bias that holds the tube near cutoffwhen no signal is present on the grid. Single-phase primarypower is applied through contactor A8K1 and step-uptransformer T1 to a bridge rectifier network. An L-sectionfilter is formed by inductor L 1 and capacitor C2.

The power supply output is applied to the grid of the poweramplifier through diode CR5. Diode CR5 blocks gridcurrent flow through the supply when the grid leak biasexceeds the fixed bias. A sample of the bias voltage isapplied through resistor R3 to front panel meter A1M1 formonitoring.

THEORY OF OPERATION

4-4.4 PA Plate Power Supply.

The power amplifier plate power supply provides platevoltage to the power amplifier. Primary components of thesupply are transformer T1, 3-phase bridge rectifier assemblyZ 1, filter choke L 1, and filter capacitor C1. A metermultiplier board, A 12A 1, samples plate voltage and allowsconstant monitoring. Input power to transformer T 1 iscontrolled by SCR (silicon-controlled rectifier) powercontrol unit A9. This unit, connected as a closed loopregulator, maintains constant power output to offsetconditions of varying line voltage.

4-4.5 Power Control Unit, A9.

Power control unit A9 regulates the 3-phase ac power inputto the power amplifier plate and the power amplifier screentransformer. SCR assembly Z 1 has three SCR pairs; onepair in series with each primary \vinding of the 3-phasepower transformers. Each pair is connected within the deltacircuit of the transformer primaries. Three control cards arelocated within the A2 card cage. Each control card controlsthe firing (tum-on) point of one SCR pair (Refer to Figures4-4 and 4-8).

A common dc control signal from power control regulatorA2A6 is fed simultaneously to each control card. Thiscontrol signal governs the firing of the SCR pairs thatregulate the input power applied to the power supplies.Upon receipt of a PLATE OFF control signal, a ground isplaced across the inputs of each card.

4-4.6 Power Control Regulator, PIO A2A6.

The power control regulator located on A2A6 provides thenecessary control signals to operate power SCR control unitA9. Assembly A2A6 supplies a soft-start power amplifierplate supply tum-on signal, a negative voltage for manualpower control, and amplifier mixer functions for automaticpower control.

IWhen the PLATE ON switch is pressed, 24 Vdc is suppliedto A2A6J 1-30. The 24 Vdc activates transistor Q1 to tumon relay A8K6. Relay A8K6 in tum supplies 3-phase accontrol power to A2TI-3. An RC time delay circuit formedby resistor R41 and capacitor C12 maintains A8K6 closedfor a short interval after the PLATE OFF switch is pressed.

ITransistors Q2, Q3, and Q4, also energized by the 24 Vdc,provide the dc tum-on signal to the gate cards. ResistorsR34 and R35, and capacitor CII modify this signal tosoft-start the high voltage power amplifier plate powersupply. Zener regulator VR4 provides -10 Vdc toMANUAL power adjust resistor A2A9RI. Transistors Q4

4-10

816R-2C

and Q5 amplify the control signal and apply the signal tothe gating cards. Capacitor C5 and resistor R36 phasecompensate the power control servo loop.

4-4.7 PA Screen Power Supply.

The 3-phase regulated voltage from the power control unitis applied through transformer T2 to a silicon 3-phasefull-wave bridge rectifier assembly A5CR1in the poweramplifier screen power supply. The output of A5CRI isfiltered and applied to the cathode circuit of the poweramplifier at the secondary center tap of filament transformerAI2Tl.

4-4.8 Driver Power Supply, PIO A5.

The driver power supply is a 3-phase, full-wave, type usinga single section choke input filter. It nominally delivers 45Vdc at 25 amperes to its load. The supply's primary poweris switched through relay A5KI which is operated by thePLATE ON circuitry. The supply is protected throughcircuit breaker A6CB3.

4-4.9 Filament Voltage Regulator, A2A4.

When the Filament Regulator Card is in the automaticmode, the filament voltage regulator detects andcompensates for sustained fluctuations in the input acvoltage (Refer to Schematic Diagram Figure 7-2). Thefluctuations are detected by a true rms detection circuitwhich in conjunction with associated circuitry, includingmotor control circuits, adjusts the setting of variabletransformer A8A2Tl. The output voltage of the variabletransformer is then applied to the primary of poweramplifier filament transformer A 12T1. The variabletransformer voltage is also applied to the primary ofdetector circuit transformer A2T4.

Voltage for the power supply circuits on the filamentregulator board is derived from sampling transformer A2T4.This ac voltage is rectified and applied to voltage droppingresistor R33. Capacitor C24 provides filtering. Athree-terminal 15 Vdc regulator U9 supplies voltage to the15 Vdc circuits with additional stabilization povided bycapacitors C27 and C28. Voltage dropping resistor R34feeds three-terminal 5 Vdc regulator UI0 while capacitorsC29 and C30 provide additional voltage stabilization. LEDDS5 indicates voltage present on the 5 Vdc line whichimplies that the 15 Vdc circuits are also powered.

THEORY OF OPERATION

4-4.9 Filament Voltage Regulator, A2A4. - Continued

Negative supply voltage is provided via diodes CRI andCR2 via resistor R3 and capacitor C24 to card edgeconnection 38 for distribution to other circuit cards in thetransmitter.

A sample of the voltage feeding the power amplifier tubefilament transformer is applied via transfonner A2T4. Thisac signal is applied to RF filtering components inductor L 1and capacitor C14. Inductor L1 has a 4.7 j.lh parallelresonance which falls in the FM broadcast band providing ahigh impedance path for frequency modulated RF signals.Capacitor C14 is a 100 pf capacitor whoseseries resonance falls in the FM broadcast band providing alow impedance shunt path for frequency modulated RFsignals. These filtering components are used in severallocations in the filament regulator card, and provide thesame filtering functions as described here.

The filament voltage sample signal is then applied to theRMS-to-dc converter circuit via voltage divider resistors RIand R2, and through capacitor C15. This RMS-to-dcconverter circuit is based around U7, a true nns-to-dcconverter integrated circuit. The converter directlycomputes the true RMS of any complex input waveformcontaining ac components. It has crest factor compensationwhich allows very accurate measurements up to 300 kHz.The crest factor of a wavefonn is the ratio of the peak signalswing to the RMS value. Components C17, R17, R 18, C18,RI9, and C20 provide time constant and filtering functionsfor the converter.

Test point 3 (TP3) provides easy access to the dc voltagerepresentation of the filament RMS voltage. During nonnaloperation of the filament voltage regulator, resistor R2 isadjusted so the output of the RMS-to-dc converter circuit is5.00 Vdc when the filament voltage has been preset to thenominal value by the operator. The output voltage is thenfed to window comparator composed ofU8 and relateddevices. The voltage references for the window comparatorare provided by UII, a very high precision IO-Voltregulator, and voltage divider components R20, R21, R22,and R23. In normal operation, resistor R20 is adjusted toprovide 5.00 Vdc at TP2. The corrected reference voltagesare then applied to their respective comparators. Pin 5 of U8has 5.05 Vdc applied, and pin 10 ofU8 has 4.95 Voltsapplied. These voltages will be correct if resistor R20 hasbeen properly adjusted for 5.00 Vdc on TP2. The 50 mVvoltage drops are provided by voltage divider resistors R21and R22. This 100 mV total window provides a total ± 10/0window for the voltage comparator, and hence for thevoltage regulator circuitry.

4-12

816R-2C

If the voltage from the RMS-to-dc converter circuit iswithin the 4.95 to 5.05 Vdc windo\v, the outputs of thecomparators will both be high and the output of AND gateU4C will go high illuminating green LED DS4 indicatingproper filament voltage is present. If the voltage from theRMS-to-dc converter is not within the 4.95 - 5.05 Vdcwindow, the circuit \vill then operate to make the necessarycorrections if switch S2 is in the AUTO position.

Assuming that switch S2 is in the AUTO position, if thefilament voltage rises above +1% of the nominal valuesetting, the following actions are taken. The output of the5.05 Vdc comparator will go low at U8-2 causing the outputofU4 to go low and DS4, the LOCK LED, will extinguish.Device U8-Il will go high bringing the input ofUI-13high. When either of the comparators goes low, indicating acorrection is necessary, U2B, U2D, and U2C incombination act as an OR gate forcing U 1-10 high which inturn triggers timer, U6. When U6 is timing, the output pin 3goes high illuminating yellow LED DS 1. At the same time,UI-3 output goes low which takes the input ofU4-1 low.This output is fed through switch S IA to inputs UI-9, Ul12 and U2-1 bringing them all low. Hence, while the timeris in its timing state, the outputs ofUIC, UID, and U2A areall high, inhibiting the actuation of relays Kl, K2, and K3respectively. Once the timer U6 has timed out, the inputs ofUIC, UID, and U2A fed from s\vitch SIA are broughthigh. At this point if the filament voltage is still above the+1% nominal value, both inputs of U 1 will be high,enabling actuation of relay Kl and the clutch assembly onthe filament voltage adjust variac motor. Simultaneously,both inputs ofUID will go high forcing its output pin 11 togo low. The LOWER LED (DS2) will be illuminated andrelay K2 will be activated which in turn actuates the lowerwinding in the motor driving the filament voltage controlvariac. Once the variac brings the filament voltage backinside the range of nominal operation, the comparatoroutput ofU8-2 will go high, and the above logic actions arereversed removing power from the filament voltageregulator variac motor.

The raise function operates just as the lower functiondescribed above, but instead activates the raise circuits. Itmay be noted that if future adjustments by the operator arerequired in the automatic mode, resistor R2 may be used asa simple filament voltage adjustment control.

The timing period of timer U6 is provided to guard againstconstantly correcting momentary excursions in the filamentvoltage. This delay timing period is adjustable from 0 to 12seconds with resistor R7.

816R-2C

4-4.9 Filament Voltage Regulator, A2A4. - Continued

If automatic operation of the filament voltage regulatorcircuit is not desired, switch S1 can be put in the MAN(manual) position. This effectively takes the regulator out ofthe circuit, but the green LED lock indicator will still showif the filament voltage is within nominal range.

While in the manual mode, momentary switches S2 and S3can be used to manually activate the clutch and raise orlower circuits respectively. Other than the timer not beingactive in this mode, these switches simulate the output ofthe comparators per the operator's command, thus manuallyraising or lowering the filament voltage. This provides aconvenient way to determine ifmost of the digital logic andthe solid state relay are functioning properly should aproblem occur. Devices U3A and U3B are provided toinsure that the raise and lower functions are not activatedsimultaneously by circuit failure or accidentally by theoperator using the manual controL

While in the manual mode, the operator may depress boththe raise and lower switches simultaneously and the onlyaction to take place is the timing of U6 as noticed by theillumination of yellow LED DS 1. This allows the operator aconvenient way to set the time delay ofU6 withoutaffecting the other circuits.

Solid state relays K 1, K2 and K3 provide a return for the acvoltages already on the windings of the clutch, and thelower and raise circuits of the variac drive motor. Relays K2and K3 also have the return path for the ac voltages routedthrough micro-switches S1 and S2 on the variac assembly.This provides a secondary measure against operating thefilament voltage regulator outside of the prescribed rangeprovided by the mechanical stops on the variac drive motor.

Figure 4-10. Circuit breaker A6CB5 is connected inside thedelta of plate transformer T1. It also serves to interruptprimary power to the PA screen transformer T2 throughassociated circuit breaker A6CB4. Circuit breaker A6CB3controls power to driver power supply (IPA) transformerT5. AC line voltage metering is provided by ac meterA2M 1. In addition to the three phase-to-phase voltages,A2M1 can monitor the power amplifier filament voltage.BLOWERS circuit breaker A6CB2 controls application ofprimary power to cavity blower Bland FAN fuses A6F7,F9, and FI2 through filament-on relay A8K2. Relay A8K2is energized when the filament switch (S2) is turned on.Application of primary power to the filament circuits, theexciter, the power amplifier bias power supply, and thepower amplifier tuning and loading motors is relaycontrolled. Filament-on relay A8KI and blower-on relayA8K2 control application of power to the regulated filamentcircuit through auto-transformer A8A2TI. Relay A8K1 alsocontrols application of power to 802B exciter A4, to poweramplifier bias power supply, PIO A10, and to the poweramplifier tuning and loading motors B2 and B3respectively. Power to the exciter and the motors is throughisolation transformer T4. Time totalizing meter A2M2 isplaced across the load side of filament-on relay A8Kl.

The filament, exciter, and power amplifier bias supply inputpower circuits are protected by associated fuses. Thesecircuits receive power from the blowers circuit breaker,A6CB2.

4-5.2 Transmitter Tum-On.

The transmitter is energized by pressing FILAMENT ONswitch AIAIS4 on the Al control panel. Relay A8K2 isenergized and is applied to the blower motors. Aftersufficient air pressure is created in the power amplifiercabinet, air switch A I2S 1 is closed and relay A8K 1 isenergized.

After a 30-second delay, relay A8K4 is energized. ThePLATE ON switch is pressed energizing relay A8K3 whichapplies 24 Vdc to the base of transistor A2A6Q3. This turnson the control amplifier, which applies input voltage to theplate and power supplies.

The transmitter may also be energized by pressing thePLATE ON switch which latches relay A8K3, andenergizes relay A8K2 through contacts 8 and 5. Pressingthis single switch (PLATE ON) enables the transmitter togo through the above sequence of blower, filament, timedelay and plate on.

4-5.3 Exciter Power Control Override.

An output override voltage is supplied to the 802B exciterwhen the plate voltage is turned OFF. This mutes the outputof the exciter while the power amplifier plate voltage isturned OFF (Figure 4-11). The voltage is applied from the

124 Vdc power supply through contacts 3 and 9 of relayA8K4 to the 802B exciter power supply regulator.

4-5.4 FWDIREFL Calibrate and Auto Power Control Unit,A2A6.

4-5.4.1 Functions. The FWDIREFL CALIBRATE ANDAUTO POWER CONTROL portion of the A2A6 cardperforms these functions (Refer to Schematic 180162):

1. The forward power signal from the directional coupleris buffered and amplified to provide a panel powermeter reading of 1000/0 at the customer's specifiedtransmitter power output (TPO). Full scale meterindication is 120% in the FORWARD POWERposition.

2. The forward power signal from the directional coupleris compared against either of two internal, adjustablevoltages for automatic power control. Two discretelevels of power control are remotely selectable andmaintain the desired power to within 10/0.

3. The reflected power signal from the directional coupleris buffered and amplified to provide a full scale readingof 12% of the customer's specified TPO on the panelpower meter in the REFLECTED POWER position.

4. The reflected power signal from the directional coupleris compared against an internal limit to smoothly foldthe forward power level back when a slowly risingVSWR level is detected. Forward power is reduced tokeep the reflected power at 5 to 60/0 of the customer'sspecified TPO.

5. A reflected power signal from the directional couplercan remove power from the transmitter and light theVSWR tally LED when a rapidly rising reflected powerlevel greater than 100/0 of the customer's specified TPOis detected.

4-16

816R-2C

4-5.4.2 Theory of Operation.

The forward power signal from the directional coupler,DC 1, is amplified and buffered by U4. Resistor R9 is anoffset null adjusted for zero output at TP 1 when no inputsignal is present. Resistor RIO is adjusted to provide a1000/0 forward power indication on the panel power meter(AIM4) at the customer's specified TPO.

The output ofU4 is also present on terminal boardAl OTB2-13, through a 2.2K ohm isolation resistor, R53, toprovide remote metering of forward power.

The positive output ofU4 is coupled through diode CRl1and compared at the inverting input ofU3 against thenegative voltage from either resistor R8 (Normal Power) orresistor R7 (Second Power) in the automatic mode. Theoutput ofU3 is used to raise or lower the transmitter platevoltage, as necessary, to maintain the selected power level.The input to U3 is switched from resistor R8 to resistor R7by relay Kl which is activated by applying +24 Vdc to relay!KI coil through terminal board AIOTB2-1. Normally,resistor R8 sets the normal operating TPO reference whileresistor R7 is adjusted for some lower value, perhapsnecessary during emergency operation with a generatorunable to supply the full power load.

The reflected power signal from directional coupler DC 1 isamplified and buffered by UI. Resistor Rl is an offset nulladjustment for zero output at TP2 when no input signal ispresent. Resistor R2 is adjusted to cause a 100/0 reflectedpower indication on the panel power meter AIM4 when thereflected power reaches 100/0 of the customer's specifiedTPO. Resistor R3 is adjusted to simulate that 100/0 reflectedpower level when the TEST switch S1 is depressed. Thisallows testing of the VSWR protection and meteringcircuits. The output ofUl is fed through resistor R43 to thegate of the VSWR overload SCR A2A5Q4 when theVSWR protect is in the enable position. Resistor R4 isadjusted to fire SCR A2A5Q4 when the reflected powerreaches 10% of the customer's specified TPO. When SCRQ4 fires, VSWR overload relay AIIK9 activates, removingpower from the transmitter and illuminating the VSWROVERLOAD LED.

The output of U 1 is also present on terminal boardAI0TB2-12 through 2.2K ohm resistor R46 to provideremote metering of reflected power.

Devices U2 and U3 form the VSWR foldback circuit. Asample of the buffered reflected power signal from U 1 isfed to U2 through resistor R5. Resistor R6 is the offset nulladjustment for U2 and is adjusted to give zero output at U26 when no input signal is present. The output of U2 iscoupled through diode CR6 to the automatic powercomparator, U3. Resistor R5 sets the level so that the outputvoltage ofU2 will exceed that ofU4, causing the power tobe reduced, when the reflected power exceeds 5-60/0 of thenormal TPO. The VSWR foldback circuit is defeated by thecircuitry of the ten second timer U5. The timer is triggeredby sampling the anode voltage ofVSWR overload SCRA2A5Q4. The response time of the VSWR foldback circuitis relatively slow. A sudden significant increase in VSWR,as in an arc, would cause the VSWR overload SCR to fire.Power to the transmitter is removed, the VSWROVERLOAD LED is illuminated and the VSWR foldbackcircuit is disabled for ten seconds. The VSWR foldbackcircuit is disabled to allow the VSWR overload circuit tosample the VSWR at full power thereby preventingoperation into a dangerously deficient load.

4-5.5 Overload Protection.

Relays A5K2, A5K3, and A5K4 are adjusted to energizeand remove power from the transmitter when an overloadoccurs in the plate or screen supply or when the VSWRexceeds a preset level. Screen current through resistor A5R8produces a voltage that is applied to relay A5K2 throughresistor A5R15. The plate current through resistor A5R7produces a voltage that is applied to relay A5K3 throughresistor A5R16. When SCR A2A2Q5 is gated on, a groundis applied and relay A5K4 is energized. Each relay isadjusted to trip at a factory preset current level. The relaycontacts are in series with plate control relay A8K3. If anoverload occurs, the corresponding relay trips andde-energizes relay A8K3, removing plate power from thetransmitter.

4-5.6 Overload and Recycle Board, A2A5.

Overload and recycle board A2A5 contains circuits thatprovide overload indication and memory, automatic poweron recycling, and filament control circuit interlock status(Refer to Schematic 180167).

When an overload occurs in the PA plate, PA screen, orIvsWR circuits, a 24 Vdc pulse is supplied to theappropriate SCR Q4, Q7, or Q8. The SCR latches and lightsits associated LED indicator on the A 1 panel to indicatewhich overload has occurred. All indicators that have beenlighted by an overload function remain lighted until OVLD

Change 5

THEORY OF OPERATION

FAULT RESET s\vitch AIAlS16 on the main control panelis pressed. Plate voltage is removed by overload relaysA5K2, A5K3, or A5K4. The 24 Vdc pulse that triggers the ISCR is simultaneously routed to the recycle circuit viadiodes CR9, CRIl, or CRl2 to be used to automaticallyrestart the transmitter.

The automatic recycle circuit provides a timed restart pulsefor up to four overload occurrences within a 30-secondperiod. The card as shipped will allow only two restartpulses in a 30-second period. However, it may bereconfigured to allow four restart pulses in a 30-secondperiod by removing the jumper between terminals A and Bon the card and replacing it between A and C.

The auto recycle begins when the 24 Vde pulse is applied talthe base of transistor Q2 causing it to conduct. The outputofQ2 is fed to timers UI and U4. Timer Ul provides a0.5-second delay, then triggers timer U3 which generates a0.5-second output pulse. This pulse is fed through gate U2Ato inverter Q3 which causes Q6 to conduct and chargecapacitor C22. The charging current of capacitor C22momentarily energizes relay Kl which closes the PLATEON circuit through switch S2. The charging current ofcapacitor C22 also flows through RECYCLE PULSEindicator LED CR6 giving an indication of the recyclecircuit operation.

Gate U2D conducts the output pulse from timer U 1 tocounter U5. Counter U5 counts the number of recyclepulses and provides a logic 1 output at terminal C \vhen fourpulses have been received. Depending on which terminalhas been strapped to terminal A, two or four recycleattempts in a 30-second period will close gates U2A, U2B,U2C, and U2D and prevent any further attempts by the cardto restart the transmitter. RECYCLE LOCKOUT indicatorLED CR2 will light to indicate this condition. When the30-second period of time has elapsed, a pulse is generated,inverted by tramsistor Q1, and applied to U5 to reset it tozero. This clears the memory and allows another sequenceto begin. If the maximum count of two or four pulses hasnot been received in the 30-second period, the timer willalso reset the counter automatically.

AUTO-RECYCLE switch S2 may be used to disable theauto recycle card when desired. This is usually done duringtune-up or maintenance procedures. RECYCLE TESTswitch S1 may be used to test the automatic recycle circuitduring maintenance procedures by simulating an overloadpulse at the input to the recycle circuit.

THEORY OF OPERATION

4-5.7 Power Failure Recycle Board, A8Al.

In the event of momentary loss of primary power, the powerfailure recycle circuit restores the transmitter to operationalstatus. Capacitor C3 maintains current flow through timedelay relay A8K4 keeping the time delay circuit active forshort term power outages and a separate circuit provides amomentary ground at pin 10 when power is restored. Themomentary ground is applied to capacitor A2A5C22 and thecharging current of this capacitor pulls relay A2A5K8 inand initiates the power ON command.

4-5.8 Auto-Manual Power Control Latching Relay andTransmitter Status Indicators.

The latching relay permits local or remote selection ofmanual or automatic power control (Refer to Figure 4-11and Status and Interlock Simplified Schematic, 189579, inpouch at rear of manual).

The latching relay is connected to the remote control panelI through terminal board A10A2. A 24 Vdc signal applied by

manual control switch A 1A 1S2 or through remote controlinterface board will latch relay Al OA2K2 in one of twostable states. AUTO PWR CONTROL switch LEDA 1A 1S1 indicates automatic power control is selected andMAN PWR CONTROL switch LED AIAlS2 indicatesmanual power control is selected.

Visual indication of TRANSMITTER CONTROLREMOTE/LOCAL switches A2A7S 1 or A2A7S2 are givenby status indicator LEDs A1AIDS22 and AIA1DSI6.

Plate control circuit interlock status indicators are providedon the Control Panel AI. RMT PLT OFF INTLK indicatorLED AIAIDSII is lighted when remote relay AI0A2K8 isde-energized. PA GRID DOOR INTLK indicator LEDAIA1DS12 is lighted when the PA grid compartment dooris closed. PA DOOR INTLK indicator LED AIAIDS13 islighted when the power amplifier plate compartment door is

closed. L REAR DOOR INTLK indicator LED A1A1DSI4,C REAR DOOR INTLK indicator LED A1AIDSI5, RREAR DOOR INTLK indicator LED AIA1DSI7, C FRPNL INTLK indicator LED AIAIDS18, and R FR PNLINTLK indicator LED AIAIDS19 are panel interlock statusindicators that are lighted when the respective panels are inplace. Panel designations refer to the three bays of thetransmitter cabinet (left, center and right) as viewed fromthe front of the transmitter. REMOTE INTLK indicatorLED AIAIDS20 is lighted when continuity exists betweenremote control interface terminal board A 1OTB 1-3 and -4.FAILSAFE INTLK indicator LED A 1A 1DS29 is lightedwhen remote relay Al OA2K8 is energized. Indicator LEDsAIAIDSl1 through AIAIDS21, except for AIA1DS16,are in series and in sequence as they are connected in thecircuit. Therefore, an interlock must be satisfied before itsstatus indicator LED will light.

4-5.9 Power Control Relays, PIO AI0A2.

Assembly AI0A2 provides remote manual power lower andraise control. When power is decreased at the remotecontrol panel, relay K4 is energized (see Figures 4-8 and4-12). Closed contacts provide 115 Vac to motor A2A9Blwhich adjusts the resistance of A2A9R1 to decrease thetransmitter power output. When the power is increased atthe remote control panel, relay K6 is energized and closedcontacts provide 115 Vac to motor A2A9B 1 which adjuststhe resistance of A2A9R 1 to increase the transmitter poweroutput.

4-5.10 Remote Relays, PIO A10A2.

Remote relays in Al OA2 parallel the front panel controloperations. Failsafe relay K8 is energized only when 24 IVdc is present in the control circuit. If the 24 Vdc is lost,the relay de-energizes and removes plate power from thetransmitter. Second power level (low power) relay K7 mustalso be energized continuously (24 Vdc) to maintain this Ifunction.

NOTE

NOTE

The transmitter plate and screen power supplieswill be operating with only one power phaseapplied in the following tests. The plate voltage,screen voltage, and RF power output will be lowerthan usual. Exact voltages in these tests areunimportant.

The 24 V dc power supply is ON when both the24V supply breaker and ac line breaker are ON.Unless otherwise indicated, the POWERCONTROL switch is set to MANUAL, thePOWER switch is set to FORWARD, the AUTORECYCLE switch is set to OFF, and all circuitbreakers are set to ON during adjustmentprocedures.

I

5. Operate POWER CONTROL ADJUST and observe thatthe plate voltage, plate current, and RF power outputchange smoothly. Note the maximum plate voltage. Ifthe power controller phase under test is good, thereshould be no breaker trips, no unusual noise from thepower transformers and no building lights blinking.

CAUTION

REMOVE PRIMARY POWER FROM THETRANSMITTER EACH TIME A GATINGCARD IS REMOVED. FAILURE TO COMPLYMAY RESULT IN CARD DAMAGE.

If none of the cards operate properly in the selected powercontroller receptacle, use a different card receptacle andrepeat the test. Perform the same test with each of theremaining gating cards in the same power controller cardreceptacle. The results should be the same for each card ifthe card is good. If all the cards operated properly, use oneof the cards to test each of the two remaining receptacles.This will check the other two power controller phases.

If all cards operate properly in one or two receptacles butnot in another, it can safely be assumed that the cards aregood but either an A2 control transformer or one of theSCR banks are defective. Experience indicates that theSCRs are least likely to fail.

5-7. ADJUSTMENTS

All transmitters are factory adjusted and pre-tuned tospecific customer requirements. No adjustments arerequired by the customer unless a broken part is replaced, aspecific assembly does not display meter readings withinallowable tolerances, or the transmitter is operated at afrequency or power output different from the frequency orpower output specified in the production test data suppliedwith the transmitter.

5-9.1.10 P.lL\. Grid Circuit. There are several reasons foradjustment of the PA grid tuning and coupling circuits, forexample:

Ao When the IPA module fails and is replaced.

Bo When the tube is replaced.

C. If there is any reason to suspect that there may be abad load on the IPA or if changes have been made inthe PA grid circuit.

When the IPA internal VSWR protection circuits are active,the IPA output power will be reduced and the fault lampilluminated. This can make grid tuning difficult if the grid isfar out of tune. The 802B Exciter can be used to adjust thegrid circuit to approximately correct tuning and couplingpositions. The 802B Exciter has a reflected power foldbackcircuit that limits the reflected power to a safe level for theexciter regardless of the VSWR presented to the exciter bythe PA grid circuit. The first six steps of the following

Change 5

The PA tube input impedance decreases asthe grid input power is increased. The gridtuning and coupling must be readjusted whenthe IPA is reconnected and the IPA outputpower is increased to normal.

The following steps shall be performed starting with lowIPA output power and zero or minimum plate voltage.Adjust grid tuning and coupling as drive power is slowlyincreased until normal drive power is reached and thenslowly increase plate voltage while adjusting the grid tuningand coupling until normal operating plate voltage isreached. Keep the IPA reflected power to a minimum whilemaking adjustments to IPA power output and plate voltage.

(See Figure 4-7.) Adjust the PA TUNING control on thecontrol panel until the capacitor is positioned approximatelymid-range. Close the plate cavity door.

NOTE

An easier way to determine position ofcapacitors Al2CSl and A12C50 is to look atthe capacitor motor drive units. Each has alimit switch actuator bar that travels with thecapacitor plate. When it is in the middle of itsrange so are the capacitors. Left side andcenter rear covers must be removed.

CAUTION

DO NOT EXCEED THE FOLLOWINGMAXIMUM RATINGS, FAILURE TOCOMPLY MAY RESULT IN DAMAGE TOTHE TRANSMITTER:

13. Slowly increase the plate voltage with the manualpower control. Notice that the IPA reflected powerwill increase as the plate voltage is increased. Adjustthe grid tuning and coupling to keep the IPA reflectedpower at minimum and IPA forward power atmaximum as the plate voltage is increased towardmaximum. PA SCREEN CURRENT:

Because of the relatively high output capacityof the 4CX15,OOOA tube and the resulting lowcavity inductance, no plate current dip will benoted at higher power levels. Tuning andloading should be adjusted in steps formaximum output power. Perform procedure inParagraph 3-3, Step 25, for best efficiency.

9. Check for power amplifier neutralization. Refer toParagraph 5-9.3.

NOTE

Compare the transmitter operatingparameters with those in Tables 3-5 and 3-6.Some fine tuning of the previously presetadjustments may be needed to bring operatingparameters into agreement with those found inthe data. If efficiency needs improvement,adjustment of the efficiency capacitor(A12A3C39) may be needed.


11. Determine if plate tuning capacitor A 12C50 isapproximately halfway between its limits.

12. If plate tuning capacitor A12C50 is not approximatelyhalf way between its limits, adjust the PA plate cavityshorting plane (Paragraph 5-9.1, Step 1) and repeatSteps 3 through 12 of this paragraph.

The power amplifier of the transmitter can be found in oneof three possible states of neutralization (neut). These are:

Experience has shown that it is best to adjust theneutralization slightly beyond the point of perfectneutralization into the region of degeneration. Moving theneutralization bars out slightly, 1/16" to 1/8", from the pointof perfect neutralization will place the PA into thedegenerative region.

NOTE

Check the transmitter for proper neutralization.If neutralization is correct, do not perform thisprocedure.

PRODUCT SERVICE BULLETIN

EIMAC 4CX15000A, 4CX20000E, 4CX25000C AND 4CW30000A TUBES JUNE 22, 2007

EIMAC has learned more about the best way to operate these tubes with regard to filament management. These operating instructions can be found in EIMAC Application Bulletin AB-18. Specifically, you should lower the filament voltage after the first 200 hours of operation. After operating a new tube for 200 hours, the filament voltage should be reduced to the power emission knee required for your output power.

WARNING

HIGH VOLTAGE IS USED IN HIGH POWER EQUIPMENT. HIGH VOLTAGE CAN CAUSE SEVERE INJURY OR DEATH. INSURE THAT ALL CIRCUIT BREAKERS

ARE OFF AND PRIMARY POWER IS DISABLED WHEN MAKNG ADJUSTMENTS INSIDE THE TRANSMITTER.

DISCHARD ALL POWER SUPPLIES BEFORE MAKING ANY ADJUSTMENTS.

INSTRUCTIONS First, stabilize the new tube emission by operating it a rated filament voltage for a minimum of 200 hours. With the transmitter in manual power control at 100% power, carefully lower the filament voltage in 0.2 volts steps, pausing for at least 30 seconds after each decrement, until you see a significant (greater than 2%) change in power output or plate current. This is the filament emission knee. Now raise the filament voltage 0.2 volts above the knee voltage. This is the correct filament operating voltage for your power output. Operation at this reduced filament voltage insures maximum possible tube life. Recheck the filament knee voltage again after 24 hours to determine if the emission is stable. If not repeatable, repeat the derating procedure again.

Please contact Continental Electronics Field Service with any questions or comments.
