PINEAPPLE TECHNOLOGY, INC. VTX2KW-A Operating and Service ManualPage 5III — TRANSMITTER INSTALLATION To insure long and reliable trouble free service from the VTX2KWA transmitter the following steps for installation are recommended.1. MECHANICAL INSTALLATION: The VTX2KWA was designed to be installed in a building pro-tected from the weather. The building should have a hard surface floor such as concrete with a mois-ture barrier. This barrier could be pressure treated wood sub-flooring which could be anchored to the concrete and to the transmitter to make the installation earth quake resistant. Allow a minimum of three feet around the transmitter cabinet for service access. The top of the trans-mitter should be clear for three feet to allow the air to exhaust from the transmitter. Air flow thru the transmitter is approximately 2000 CFM. Provisions for air inlet and exhaust from the room must allow air flow with minimal obstruction. In the event that the room temperature exceeds 35 degrees Celsius, cooling air must be provided so that the room temperature will not exceed 35 degrees Celsius under worse case conditions. Notice: This equipment is HEAVY and must be handled by professional movers with proper equipment. Any damage caused by the installers is not covered under warranty. Check to insure that installing crews have proper insurance coverage.2. GROUNDING: Transmitter grounding is VERY IMPORTANT and must be done correctly for safety and operational reasons. A typical installation may be done as follows: Use a heavy gauge wire such as #2 AWG strained copper or solid copper buss 1 inch wide by 1/8 inch thick for connections. The bonding between the transmitter and the ground rods must be good quality and protected from corrosion. The ground wires should run over the floor and connected to the ground rods located outside the building. The wire should not go thru the concrete floor but over and around it. 3. AC WIRING: A ten foot cable has been provided with the transmitter to facilitate the connection to the AC Main power source. Connections to the AC Main should be made as follows: RED and BLACK are connected to the 208-240 VAC SINGLE PHASE terminals WHITE WIRE is connected to the NEUTRAL terminal GREEN WIRE is connected to the SAFETY GROUND NOTICE: All wiring of this type must be done by A QUALIFIED ELECTRICIAN and must conform to LOCAL and NATIONAL Wiring CODES. Consult with your electrician to insure that the proper breaker size is selected for the main circuit.4. ANTENNA CONNECTION: The transmitter is equipped with a 7/8 EIA Flange connector located at the top of the rack. Connecting the transmitter to the antenna must be performed by qualified person-nel. Conditions vary from site to site so some engineering may be required to insure that the antenna is receiving the correct amount of power to comply with FCC licenses and to insure safety from lighting etc. III — TRANSMITTER INSTALLATION
PINEAPPLE TECHNOLOGY, INC. VTX2KW-A Operating and Service Manual IV — TRANSMITTER TURN-ON PROCEDUREPage 6IV — TRANSMITTER TURN-ON PROCEDUREBefore applying AC Power to the transmitter for initial turn on and check out, the installation should be approved by a qualified broadcast engineer. The Turn on procedure that follows is recommended by Pine-apple Technology, Inc. engineering staff:1. Check transmitter load or antenna for proper installation and connection to the transmitter.2. Open the transmitter and inspect all cables and wires for lose connections or broken wires in the rack assembly3. Check for damage to the equipment mounted in the rack.4. Check all AC breakers and on/off switches to ensure that all are OFF.5. TURN ON THE MAIN AC BREAKER LOCATED IN THE SUB-PANEL WHERE THE AC POWER CORD WAS CONNECTED.6. TURN ON THE MAIN AC BREAKER LOCATED ON THE ACDIS2 POWER DISTRIBUTION PANEL LOCATED ON THE FRONT OF THE TRANSMITTER. A GREEN LIGHT SHOULD COME ONE INDICATING POWER IS ON.7. TURN ON THE AC SWITCH LOCATED ON THE FRONT OF THE ADP500. THE INDICATING LIGHTS SHOULD BE ON AND READY FOR OPERATION8. TURN ON THE AUX BREAKER LOCATED ON THE ACDIS2 FRONT PANEL. THE PA FANS AND THE RACK EXHAUST FANS SHOULD COME ON.9. TURN ON THE POWER SUPPLY BREAKERS LOCATED ON THE FRONT OF THE ACDIS2. CHECK THE AC 2008 POWER MODULES (6) EACH TO SEE IF THE GREEN LIGHTS ARE INDICATING NORMAL OPERATION.10. USING THE ADP500 & PAS10 CHECK THE IDLING CURRENTS ON EACH PA TO ENSURE THAT THE CURRENTS ARE IN THE CORRECT RANGE. TYPICAL RANGE IS 1.5 TO 2.5 AMPS. SEE ADP500 OPERATING SECTION FOR DETAILSNOTICE: The Modulator/driver has been set at the factory so that the output power indication on the ADP500 will show 100% or 2 KW p-sync power level. It is important to read the instruction manual sup-plied with the modulator to locate key adjustment devices on the front panel. The output level adjustment will be necessary for the next step in the turn on procedure.11. Locate the level adjustment on the modulator/drive and turn the level down to minimum or CCW.12. Turn on the power switch located on the modulator/up-converter rear panel.13. Apply a video signal (1 volt P-P) to the video input terminal14. Slowly increase the output level adjustment while watching the RF Output level on the ADP500 until it reads to 50%.
PINEAPPLE TECHNOLOGY, INC. VTX2KW-A Operating and Service Manual15. Using the ADP500 reflected power indication check the LOAD reflected power. This should be less that 5% reflected. 16. Return to the PA current readings on the ADP500 to verify that all the currents are approximately the same. 17. With successful performance to step 17, the transmitter output power can be increased using the output level adjustment on the modulator to achieve 100%. The aural power can be added at this time not exceeding 10% of output p-sync power as indicated on the ADP500. V — THEORY OF OPERATIONSA. INTRODUCTIONThe VTX2KWA transmitter was designed to meet or exceed all FCC applicable specifications for TV Broadcast Equipment. Special attention was given to the selection of sub-assemblies and components to achieve maximum reliability and minimum down time. The construction of the VTX2KWA is BASIC and MODULAR with most components field replaceable. Special emphasis was placed on KEEPING IT SIMPLE and returning to more traditional transmitter layouts and instrumentation. This transmitter was designed for Analog (NTSC) transmission with provisions and options available to convert to Digital Service when necessary.Refer to the VTX2KWA block diagram (page 12) for an overview of the transmitter architecture. The key subassemblies are listed below followed by a brief description. This will give the technician basic infor-mation needed to understand the operations of the transmitter and the function of each subassembly.SEE SECTION VI.A FOR PARTS LIST (page 13) B. ACDIS2 AC & DC DISTRIBUTIONThe ACDIS2 is the primary AC power inlet module. The VTX2KWA transmitter was designed to except 208 to 240 V AC SINGLE PHASE using a FOUR (4) wire connection. The four wires are 2 wires for 208-240V AC single phase 1 wire for neutral connection 1 wire for safety ground connectionCAUTION: Connection to the AC Primary Source must be made using all four wires listed above. Follow the wiring instruction given in the AC WIRING section III. 3 (page 5). If not followed, severe damage to the transmitter and or electrical shock is possible.The ACDIS2 performs the following functions:1. Provides a primary AC power breaker point to shutdown the transmitter.2. Provides 208 VAC single phase power to each of the 2 KW DC power supplies with individual breaker points for added safety.3. Provides 110 VAC circuits for Modulator, ADP500, Auxiliary Power Source, and AUX Power where needed.V — THEORY OF OPERATIONSPage 7
PINEAPPLE TECHNOLOGY, INC. VTX2KW-A Operating and Service Manual4. Analog metering is provided to monitor the Power supply voltage and current being applied to the RF Amplifier stages5. Power supply current sharing test points are provided for checking current sharing between power supply modules. SEE SECTION VI.B FOR SCHEMATIC AND PARTS LIST (page 14) C. AC2008 2 KW POWER MODULEThe VTX2KWA transmitter is designed with over 8 KW of DC power available to the transmitter. To achieve this level, the power supply is made up of four RR6000 (PTI P/N AC2008) power module mounted into TWO mainframe assemblies RU2 (PTI P/N AC2009) which are capable of managing three 2 KW modules each. The power modules are “HOT PLUGGABLE” and can be removed or installed without turning off the transmitter. Each power supply modules has OVER VOLTAGE, OVER CURRENT, AND OVER TEMPERATURE protection as well as a fault signal in the event of a failure.REFER TO MANUFACTURER’S MANUAL PROVIDED WITH THE VTX2KWA.D. PAS10 & ADP500 PERFORMANCE MONITORThe PAS10 & ADP500 PERFORMANCE MONITOR provides the following functions:1. Monitors FORWARD AND REFLECTED POWER to the antenna and presents it as a percentage of power rating. The transmitter comes set to 100% P-Sync power based on the ratings of the transmitter.2. Monitors Aural Power as a percentage of P-Sync rating (10 % typical)3. Provides a HIGH ANTENNA VSWR MONITOR In the event of an antenna or coax failure where the reflected power exceeds 25% the transmitter will shutdown. Front panel LED with change from green to red in case of a fault. 4. Provides current monitoring of all the pallets used in the six V600LDV2 power amplifier assemblies. The current levels can be read directly from the multi-meter on the front panel. Individual pallets are selectable on the ADP500 and the PA assemblies are selected using the PAS10. In normal operations, a PA FAULT is indicated by going from green to red. RED indicates that the current level is below 500 ma and a transistor could have failed. To read the actual current, select the appropriate PA Bank using the PAS10. The ADP500 will now display status of each pallet in that PA. The multi-meter will read the actual current. 5. A PA INHIBIT switch is provided for failure diagnostic purposes. When activated, this switch allows the technician to monitor the bias currents for each pallet. These readings should be recorded when the transmitter is first installed and used as a reference. This is the best way to trouble shoot possible tran-sistor problems. When in the PA INHIBIT mode, the RF PWR OFF LED will change from green to red indicating that the “SHUTDOWN LINE” Is at a TTL 0 state and the output power has been reduced to near zero.6. An RF MONITOR port (BNC) is available to connect a spectrum analyzer or other test equipment for monitoring the output signal.V — THEORY OF OPERATIONPage 8
PINEAPPLE TECHNOLOGY, INC.

PINEAPPLE TECHNOLOGY, INC. VTX2KW-A Operating and Service ManualPage 42VII — ROUTINE MAINTENANCEVII — ROUTINE MAINTENANCEThe following KEY MAINTENANCE AND PERFORMANCE CHECKS should be made monthly or more frequently in some environments where dust is a problem:TRANSMITTER• Remove and clean the air filters with a light detergent and dry completely before re-installing. Dirty filters will cause PA amps to shutdown resulting in a loss of RF Power. Spare filter P/N 990199 is available from Pineapple Technology Inc.• Check and record the Voltage and Current meter readings on the ACDIS2 (AC AND DC DISTRIBU-TION UNIT LOCATED NEAR THE POWER SUPPLIES). NOTE: current readings will vary with picture content.• Using the ADP500 & PAS10 record the bias level settings on each PA Pallet by selecting the appropri-ate PA with the selector switch. To make this measurement of BIAS ONLY it is necessary to activate the PA INHIBIT switch momentarily for each reading. • Using the ADP500 check and record the RF Output power level to insure that it is still reading 100% +/- 10% from the previous settings.• Using the ADP500 check and record the VSWR (Reflected power) to insure that it is still reading only a few percent indicating normal load operations.• Using the ADP500 check and record Aural power readings. This is normally set at 10% of P-Sync.Expect this to vary only a few percent from reading to reading.• Carefully inspect RF Output coax and coaxial fittings for excessive heating or discolorationFACILITIES • Clean all air inlet filters and exhaust outlets to insure that the transmitter is getting clean unobstructed air flow.• Perform recommended service on air condition systems• Rodent traps or baits should be renewed to keep the facilities clear of these pests which can damage to the transmitter
PINEAPPLE TECHNOLOGY, INC. VTX2KW-A Operating and Service ManualPage 43VIII — ADJUSTMENTS AND TUNINGVIII — ADJUSTMENTS AND TUNINGThe VTX2KWA is basically a broadband transmitter with a few frequency selective sub-assemblies which comply with FCC Type Certification requirements. A list of these sub-assemblies are listed below and fol-lowed by general instructions where applicable:A. MODULATOR Instructions for making adjustments to the modulator are included in the Manufac-turer’s Instruction ManualB. BPV2KW Band Pass filter comes adjusted to the channel as purchased. To change frequency would require a tuning adjustment to the filter. To perform this adjustment it is necessary to use a NET-WORK ANALYZER and a signal generator with necessary I/O Adaptors to connect to the filter. The Technician performing this adjustment should be skilled in tuning Band Pass Filters. If the target frequency is outside of the tuning range of the filter, it becomes necessary to purchase a new filter. Replacement filters and service is available from Pineapple Technology Inc.C. V600LDV2 POWER AMPLIFIER MODULE: The V600LDV2 has three areas where adjustments may be necessary over time or in the event of a frequency change. These areas are:1. Bias adjustments: The LDMOS FET devices used in these pallet amplifiers are set to 500ma/device side or a total of 1 amp/device. This adjustment can be made on the bench by first termi-nating the input and output with 50 ohm terminations. Apply 31 volts DC to the PA using a power supply that can provide a minimum of 15 amps. Note: a cooling fan will be necessary to cool the amplifier during this adjustment. To adjust biases it is best to turn all the bias adjust resistors CCW or to minimum on the pallet being adjusted. Using a clamp on DC AMP Meter connected to the DC Feed terminal located on the DC ISOLATION AND CURRENT MONITOR BOARD measure the current levels. The first resistor is increased to 500ma indicated on the Amp meter. Repeat this adjustment for each addi-tional resistor for reading of 1.0 A, 1.5 A, and 2.0 A. This will indicate that each device half is set to 500 ma. This concludes the bias adjustment procedure. This adjustment should be made at all time when a device has to be replaced. Normal bias ranges from 1.5 amps to 2.3 amps per pallet as indi-cated on the ADP500/1000. DO NOT USE THE ADP500/1000 CURRENT READINGS FOR MAKING BIAS ADJUSTMENTS.2. PA PALLET RF circuit tuning: These circuits are Broadband and Fixed tuned providing no adjustments. Any turning at this level is performed by the factory.3. GAIN & PHASE MATCHING: Each V600LDV2 must be gain and phase matched to each unit in the system. This is accomplished by maintaining tight manufacturing tolerances on devices, cables, and component selection. No adjustment are required at this level and should not be attempted in the field
PINEAPPLE TECHNOLOGY, INC. VTX2KW-A Operating and Service ManualPage 44VIII — ADJUSTMENTS AND TUNINGD. PHASE MATCHED CABLES: The cables used to connect the splitter to the PA Amplifier inputs and those provided to connect the PA Amplifiers to the combiner are phase matched. If a cable is damaged and needs to be replaced, additional cables are available from Pineapple Technology Inc. The customer my manufacture additional cables, however the same coax type, connector, and lengths must be used. E. ADP500/1000 WATT METER: This unit comes calibrated from the factory for the rated power level of the transmitter. Adjustments are not recommended in the field.
PINEAPPLE TECHNOLOGY, INC. VTX2KW-A Operating and Service ManualPage 45IX — PROBLEM SOLVING/TROUBLE SHOOTINGIX — PROBLEM SOLVINGThe VTX2KWA is a complex assembly of Digital and Analog circuits and in many cases it is advisable to contact Pineapple Technology Inc for assistance. If it is necessary to perform field service on the transmit-ter, most parts are available from Pineapple Technology Inc for next day shipment.The failure analyzes of the transmitter starts off with the following assumptions:A. The transmitter is connected to an AC Source which is within the specified voltage range and has ample power to run the transmitter. This would normally be 208-240 V AC SINGLE PHASE with a minimum of 60 Amps available. B. The antenna has been checked out and verified to have a VSWR of 1.2:1 or better.C. The room temperature is < 35 degrees Celsius.D. There are no restrictions on the air flow in or out of the building E. The video and aural signals, to the Modulator, comply with stated specifications.CHECKING THE WARNING LIGHTSMFA1KW: This unit has dual performance indicator lights located above the air inlets. One set of lights for each PA Assembly located inside the unit. HS OVER TEMP GREEN NORMAL RED FAULT+28 VDC GREEN NORMAL RED FAULTFAN SUPPLY GREEN NORMAL RED FAULTHS OVER TEMP FAULT could indicate one of the following problems:a. Room temperature to high and the HS are over heatingb. High VSWR on PA output port will cause to Dump Load sensor to Fault.c. Air filters are dirty and need to be cleaned d. Exhaust fan failure. (located in the top of the rack) +28 VDC FAULT could indicate a power supply failure. Check the ADP500 & PAS10 for PA voltage and current readings. The power supply modules will also indicate a lost of power. FAN FAULT indications could mean that the PA blower has failed or there has been a lost of AC power
PINEAPPLE TECHNOLOGY, INC. VTX2KW-A Operating and Service ManualPage 46IX — PROBLEM SOLVING/TROUBLE SHOOTINGto the fan. There is also a fuse located just inside of the front panel in case there is a locked rotor failure condition. To access the fuse, the MFA1KW must be removed for the rack and the top cover removed. The fuse is located just behind the front panel.ADP500: There are a number of fault indicator lights on this unit that can be used for trouble shooting possible problems with the transmitter.With normal operating conditions, all the LEDs located on the front panel should be green. Red lights could indicate a fault in normal operations of the transmitter. Fault indicators are listed below:a. ANT VSWR HIGH light is RED. This indicated that the antenna reflected power exceeds the set point in the equipment which is normally set to 10 %. When this LED is on, the transmitter shutdown line is pull down to ZERO and the transmitter RF PWR OFF LED will also light RED indicated that the transmitter has been shutdown at the driver level. This condition will automatically reset when the problem is corrected. CHECK THE ANTENNA FOR POSSIBLE FAULTS.b. RF PWR OFF light is RED. This will occur anytime the “SHUTDOWN LINE” is pulled to ZERO. This control line is pulled to ZERO with any of the following faults:c. ANT VSWR HIGHPA INHIBIT SWITCH IN THE INHIBIT MODENOTICE: ONLY THE PA INHIBIT SWITCH OR THE ANT VSWR HIGH WILL SHUTDOWN THE TRANSMITTER DRIVE CAUSING THE RF OUTPUT TO FALL TO NEAR ZERO.d. PA1 THRU PA5 LEDs RED would indicate that the PA Pallet current level has fallen below the set point and could indicate a transistor failure.RR6000 (AC2008) POWER SUPPLY MODULESThe Power Supply module has two warning lights located on the front panel. Normally these lights are GREEN indicating that the AC Line voltage and the Over Voltage circuits are within their normal range. Should either go out of range, the lights will turn RED and the power supply module will shutdown. This will reduce the available power to the RF Stages and could result in lower RF Output Power from the transmitter. If this happens, turn off the transmitter for about 1 minute and then turn it back on. If this warning continues, the module should be removed from the rack and returned for service and a spare module should be installed to maintain normal operations.NOTICE: The VTX2KWA transmitter has 4 each 2 KW power modules. Under normal conditions, this is enough head room to allow the removal of one power supply module with little or no reduction in output power. In the event it becomes necessary to remove a module and the RF Output power drops, the RF Drive level from the Modulator can be reduced to a point where the DC Volt meter on the ACDIS2 reads 31 volts. This is the maximum output level obtainable with one power supply module removed. On this transmitter that could be a reduction of less than 500 watts in operational output power. This will keep the station on the air till the new power supply module arrives. DON’T FORGET TO TURN THE DRIVE LEVEL UP AFTER INSTALLING THE NEW SUPPLY TO RETURN TO 100% OPERATION.
