It is not intended to contain a complete statement of all safety precautions, which should be observed by personnel using this or other electronic equipment. DOCUMENTATION - Read, retain and follow instructions before operating the equipment. There is a lot of useful information in the manual, and besides, we spent a lot of time writing it! ENVIRONMENT - To reduce the risk of fire or electric shock, do not expose this equipment to rain, moisture, or rye and sodas at the company Christmas party. Refer all servicing to qualified service personnel. SERVICING - Do not attempt to service this equipment yourself as opening or removing covers can result in a warm tingly feeling and will void the warranty. Refer all servicing to qualified service personnel. I-1 Technalogix Ltd TAVD-500 Transmitter Safety and First Aid Personnel engaged in the installation, operation, maintenance, or servicing of electronic equipment are exposed to the hazard of high voltage. It is imperative that all safety regulations and precautions are consistently observed. Knowledge of first aid procedures is recommended. The following information is presented as a reference only. • At all times, avoid placing any part of the body in series between ground and circuit points, whether power is on or off. • Dangerous voltage may be present in equipment even though power is off. Do not open the cabinet. Refer servicing to qualified service personnel. • It is the duty of all personnel to be prepared to give adequate emergency first aid treatment and thereby prevent avoidable loss of life. • There are three principle degrees of burns, recognizable as follows: • a first-degree burn reddens the skin. • a second-degree burn blisters the skin. • a third degree burn chars the flesh and frequently places the victim in a state of shock accompanied by respiratory paralysis. • Respiratory paralysis can cause death by suffocation within seconds. It is imperative that the approved methods of artificial respiration are initiated immediately and continue until the victim’s breathing is normal. • A muscular spasm of unconsciousness may render the victim unable to break free of the electric power. If this is the case, turn the power off immediately. DO NOT TOUCH THE VICTIM OR YOU MAY SHARE THE SAME PREDICAMENT. • If the power cannot be turned off immediately, very carefully loop a dry rope, article of clothing, length of strong cloth or a rolled-up newspaper around the victim and pull the victim free of the power source. Carefully avoid touching the victim or clothing. • Once free of the power source, the victim must be placed in a reclining position and covered with a blanket or newspapers to keep warm. At the first opportunity, enlist help in summoning a doctor. If a doctor cannot be summoned, transport the victim to the doctor or a hospital. Be sure the victim is kept well covered and warm while awaiting professional treatment. I-2 Technalogix Ltd TAVD-500 Transmitter Operating Safeguards It is a known fact that our broadcast transmitters and translators enjoy 50-ohm load impedances. So much so, that it is imperative you maintain 50-ohm impedances throughout your system. In return, your equipment will provide you with maximum power transfer to the antenna and decreased reflected power heading back towards the amplifier pallets, reducing the amount of magic smoke that gets let out of the power amplifier. Before anything is turned on, ensure that there is a 50-ohm path from the output of each stage to the input of the next, all the way to the antenna. In addition to maintaining proper 50-ohm impedances throughout the signal chain, it is also important, whenever possible, to make sure the RF drive going to the input of the power amplifier is removed before turning on or turning off the DC power supply. This is because all of the RF transistors used in the individual amplifier pallets are fabricated with LDMOS (Laterally Diffused Metal Oxide Semiconductor) technology. Nice and linear yes, but they do not like to make any RF power when their supply voltages are not within a specific range. When you first turn your power amplifier on or off, the DC power supply’s output voltage may take a while to stable out to a safe operating voltage. Ten seconds wait before applying the RF drive will ensure no issues arise. Our power amplifiers are designed to reliably generate a specific RF output power. Failing to adhere to overdriven amplifier warnings can decrease the reliability of your system, and frankly, makes our repair department busy and grumpy. If you need to transmit to a little larger coverage, you are better off increasing antenna gain, and more importantly, antenna height above average terrain. On TV and FM broadcast frequencies, insufficient antenna height puts an upper limit on your range, regardless of power levels, as the distance from your antenna to the radio horizon is limited.

Technalogix Ltd II-5 TAVD-500 Transmitter Section III – Overview Standard Features • Narrow output bandpass filter allows adjacent channel operation • Front panel Liquid Crystal Display (LCD) to monitor forward and reflected RF power, and DC voltage • Microcontroller-based monitoring and control ensures amplifier will never be overdriven and high VSWR will not damage amplifier • AC circuit breaker on back panel to eliminate replacement of fuses • All aluminium enclosure maintains power amplifier’s light weight • Simple design using commonly available parts ensures reliable operation Technalogix Ltd III-1 TAVD-500 Transmitter Principle of Operation The TAVD-500 power amplifier supplies a 500-watt (rms) 8VSB television signal on any of the VHF television channels 2 through 13. Please note that channel selection must be made at time of order, as the transmitter or translator is calibrated and tested to the channel requested and is not field tuneable. The TAVD-500 power amplifier is a modular solid-state system comprised a TAVD500 500-watt broadcast amplifier utilizing readily available RF components wherever possible, thus enhancing the serviceability of the equipment. Each TAVD-500 is comprised of a VHFTV-25 and a VHFTV-200 driver pallet and (4) VHFTV-400 final pallets that are combined to create 500 watts (rms) 8VSB power. The amplifier modules are stable for high reliability and long service life. The TAVD-500 features ultra linear amplification and individual channel RF output bandpass filtering. The following block diagram illustrates the 500-watt system.

It then passes through an RF attenuator to limit the output power level of the power amplifier and to help buffer any transients that may come into the power amplifier. After attenuation, the signal gets preamplified through the two driver pallets before the signal gets split into (4) signals for final amplification. The output of the (4) final amplifier pallets get combined and passes through an isolator. Finally, the signal passes through a dual directional coupler for monitoring purposes before heading out to the combiner/filter enclosure and then through to the antenna.

The VHFTV-25-L has a typical gain of 36dB and the VHFTV-25-H has a typical gain of 34dB. These pallets draw no more than 3.5Adc total drain current (the exact bias and drain currents of your system are found in the spec sheet supplied with each manual). The quiescent and drain currents can be measured on the VHFTV-25 pallet by measuring the voltage drop across the current sense resistor found directly at the DC power supply lead input to the pallet. This resistance is 0.01-ohms, providing a 10mV per ampere ratio. The VHFTV-200 pallet is a two stage ultra linear class-A linear pallet. The VHFTV-200-L and –H pallets have a typical gain of 20dB and the VHFTV-200-H has a typical gain of 18dB. These pallets draw no more than 4 Adc total drain current (the exact bias and drain currents of your system are found in the spec sheet supplied with each manual). The final amplifier stage is comprised of a VHFTV-400-L or VHFTV-400-H amplifier pallet and are characterized with typical gains of 18 dB (low band) or 16dB (high band) and maximum drain currents of 17 A (low and high band) for 8VSB systems. Each of the amplifier pallets is connectorized. All amplifier pallets must have the transistor drain voltages reach at least 26Vdc before the RF drive is applied. Technalogix Ltd IV-1 TAVD-500 Transmitter Technalogix Ltd. 25 Watt High Band VHF Pallet PA25-VHF-H S. Kazarian November 12, 2001 Technalogix Ltd. 200 Watt High Band VHF Pallet P200-VHF-H R.S. McDonald December 17, 2001 Technalogix Ltd. 400 Watt High Band VHF Pallet P400-VHF-H R.S. McDonald July 30, 2001 Filter The passive bandpass filter rejects spurious and harmonic output products and passes the VHF channel RF output. The cavity resonator uses aperture coupling and is a linear resonator design. Typical insertion loss is 0.6 dB to 1.0 dB depending on channel frequency. Average roll off is –33 dBc at a point 4.5 MHz below the peak visual carrier frequency and –30 dBc 9.0 MHz above the peak visual carrier frequency. The filter is DC grounded on both the input and output for additional lightning protection. Directional Coupler The Technalogix dual directional couplers provide DC voltages proportional to forward and reflected RF power monitoring. These analog voltages are converted for processing using analog-to-digital converters and provide the control system with valuable data for monitoring purposes. Output power should be set following the operating procedure found elsewhere in this manual. The directional coupler has a typical insertion loss of 0.5dB and its Type N connectors can handle 1,500-watts peak while the 7/16” DIN connectors can handle over 3,000-watts peak. Isolator The power amplifier pallets are protected in part by the isolator located in the power amplifier enclosures. It is actually made up of a circulator and 50-ohm dump resistor. The circulators’ specifications include an insertion loss of less than 0.2dB with an isolation rating better than 20dB. Any reflected power gets dumped into the flanged power resistor. Even though the flanged power resistor is rated for only 150-watts, and there could potentially be 500-watts being reflected back into the circulator, the software will recognize quickly that reflected power is present and turn the carrier off. This way, there is instantaneous protection due to the isolator setup and long term protection due to the software. Technalogix Ltd IV-5 TAVD-500 Transmitter Section V – Power Supply Switching AC-DC power supplies are used to power the amplifier pallets, the control circuits, and all of the fans. The power supply is set at 30.0 Vdc nominally. All fans run off this same supply, though they pass through a series dropping resistor to lower the supply voltage, as the fans are 24Vdc. The (2) power supplies found in the power supply enclosure are Mean Well RSP-1500-27. The switching power supplies are fully protected against short circuit and output overload. Short circuit protection is a cycling type power limit. The internal AC fuse is designed to blow only on a catastrophic failure in the unit – the fuse does not blow on overload or short circuit. The thermal shutdown automatically recovers when the power supply chassis cools down. AC (220Vac) is fed into the power supply enclosure via a filtered AC entry and then through a circuit breaker.

The control system also allows the user to monitor and control the transmitter from both the front panel and the remote access port. Five modules comprise the Insight control system. These modules work together to provide all the functions of the control system. The modules are: User Interface, Coupler Conditioning, RF Conditioning, Temperature Sensor, and the TxNET modules. The operation of each module is outlined in the following sections. For the TAUD-20-3 only, all three Power Amplifier chains are controlled by one User Interface Board and all three Power amplifiers are monitored on one LCD screen. In case of an alarm, the unit number and the fault will be displayed on the front panel (i.e. PA2 High Reflected Power). During the alarm situation only the error screen will be displayed while the other two units continue to run normally. The alarm buzzer will sound different on PA1, PA2 and PA3. User Interface Module The primary function of the User Interface module is, as the name suggests, providing the user interface for the control system. This circuit board is mounted to the front panel of the transmitter, directly behind the LCD display. The membrane switch on the front panel is also connected to the User Interface module. These components together provide the user with the ability to monitor the transmitter from the front panel. The following parameters can be monitored from the front panel: • Forward (incident) power at the transmitter output. • Reflected (reverse) power at the transmitter output. • DC voltage of the transmitter power supply. • DC current for each pallet in the transmitter. • Digital attenuation for input signal. • Temperature of the heat sink of the transmitter. • The time since the transmitter was last shut down. Technalogix Ltd VI-1 TAVD-500 Transmitter The hardware of the User Interface module is based around a microcontroller (U112). This microcontroller interfaces directly with the LCD and the membrane switch to provide output and receive input from the user. The microcontroller also communicates with the Coupler Conditioning board over a Controller Area Network (CAN) bus. This communication is facilitated by two ICs, U113 and U114, and passes through a CAT5 cable attached to connector J106. The communication link with the Coupler Conditioning module allows the User Interface module to receive information about the forward power, reflected power, and temperature of the transmitter, as well as relay commands from the user to the rest of the system. If the transmitter includes more than one amplifier enclosure, a second CAN connection will be present between the User Interface module (J105) and the TxNET board to facilitate communication between enclosures. Other elements of the User Interface module are also controlled by the microcontroller. A buzzer (BZ101), a status LED (D113), and a relay to control the backlight of the LCD (RL101), are all controlled through a buffer (U116). In order for the User Interface module to monitor the current draw of each pallet in the system, the DC supply wires pass through the User Interface module on their way from the power supply to the pallets. The DC enters through connector J101 (6-position) from the power supply, and exits through J102 (10-position) to go to the pallets. As the current passes through shunt resistors (R117/R118, R120/R121, R123/R124, R126/R127, R129/R130), the voltage drop is monitored by U101 through U105, buffered by U106 through U108, and sent to the analog to digital converter integrated into the microcontroller. There are up to five circuits for which the current is monitored by this system. As the DC supply passes through the User Interface module, it undergoes filtering to ensure that the supply to the pallets is as clean as possible. Each of the five circuits passes through a network of transient voltage suppressors, capacitors, and inductors. Each connection is also fused at the input to insure an over-current condition does not persist. The fuses are a replaceable mini blade type fuse with a 42V voltage rating, and a current rating depending on application. Coupler Conditioning Module The Coupler Conditioning module serves to monitor the output of the directional coupler which provides a voltage proportional to the forward and reflected power at the output of the transmitter. The Coupler Conditioning module also interfaces with each of the other boards in the control system, acting as the hub of communications for the system. Lastly, the Coupler Conditioning board sends and receives signals through the remote access port, via the TxNET board. The analog signals produced by the coupler for forward and reflected power are passed onto the Coupler Conditioning module by connectors J206 and J207, respectively. Each signal is then filtered by LC networks. The analog signals are converted to digital by an analog-to-digital converter integrated into the microcontroller U202. Technalogix Ltd VI-2 TAVD-500 Transmitter Aside from taking readings from the coupler, the microcontroller on the coupler conditioning module also interfaces with the RF Conditioning module (through J201) and the Temperature Sensor (through J202). The microcontroller interfaces with the system CAN bus using U203 and U204. Through the CAN bus, the Coupler Conditioning board is able to communicate with the User Interface module, and any other amplifier enclosures that are in the system. The last task of the Coupler Conditioning board is to send and receive remote access signals to and from the TxNET board. Two analog outputs, proportional to forward and reflected power and produced by the digital-to-analog converter U207 after it receives input from the microcontroller. The analog outputs are then buffered by U206 before being sent through J208 and J209 to the TxNET board. J208, along with J209, also bring the digital inputs and outputs from the TxNET board to the Coupler Conditioning module. The digital signals are then connected to the microcontroller through the opto-isolators U209 through U213. RF Conditioning Module The RF Conditioning board is located at the RF input of the amplifier. Its main function is to act as a variable attenuator, so that the control system can add attenuation to the input of the amplifier in order to limit the output power of the transmitter. The RF signal comes in to the RF Conditioning module through J301 before it passes through a fixed attenuator (Pi-network) made up of R301, R302, and R303. The signal then passes through the digitally-controlled variable attenuator U302 before exiting through J303. The input control for the digital attenuator comes from the Coupler Conditioning module through J304. The input signals are passed through the opto-isolators U302, U303, and U304 before being sent to the digital attenuator. In total, five control signals go to the digital attenuator, allowing for attenuations of up to 31dB in 1dB steps. Temperature Sensor Module The Temperature Sensor module is a small board mounted to the main heatsink of the amplifier. The main purpose of the temperature sensor module is to take temperature readings of the heatsink. The temperature sensor IC is U701 which, after it has taken a reading, relays the digital information to the Coupler Conditioning module through J702. Also passing through J702 is a driver disable signal coming from the Coupler Conditioning module. The Temperature Sensor module simply takes this signal and passes it through to a pad, where a wire connects it to the driver pallet. Technalogix Ltd VI-3 TAVD-500 Transmitter TxNET module The TxNET module is simply a passive board that acts as an interface between the wiring on the inside of the amplifier enclosure and connections on the outside of the enclosure. There is a high power version for systems that have more than one amplifier enclosure and a low power version, which does not have external enclosures aside from the modulator. The DB-25 connector for the remote port (J602) is attached to the TxNET module. The signals travelling through this port are connected to the Coupler Conditioning module through J601 and J603. The TxNET module also includes up to three straight through RJ45 connection pairs: J604 to J605, J606 to J607, and J608 to J609. These connections are only used on systems with multiple enclosures, to pass control signals between enclosures; otherwise a low power TxNET is used. Technalogix Ltd VI-4 TAVD-500 Transmitter Remote Port The remote port allows external control of the transmission system via the DB25. The Power Amplifier enclosure does not include all the pins in the remote port like the Combiner/Filter enclosure. The overall functions of each pin on the remote port are indicated in the following table (see the Installation section for the specifics to each enclosure): Pin Number Description Ground Forward power sample1 Reflected power sample1 Carrier off2 Carrier on2 Increase carrier level (level must have been decreased) 2 Decrease carrier level (1dB increments) 2 Reset2 11 High temperature flag3 12 High VSWR flag3 13 Amplifier overdriven flag3 14 +5Vdc 15 +3.3Vdc 16 Ground 17 Ground Notes: 1. Analog output with voltage ranging from 0 to 5Vdc. 2. TTL level digital input, active on rising edge. 3. TTL level digital output, active high. All other pins are not to be connected. Please see the Installation section for the specific pins that are used for each enclosure. Technalogix Ltd VI-5 TAVD-500 Transmitter Fault Shutdowns On the LCD (Liquid Crystal Display) the following messages may appear: The Amplifier overdrive shutdown is set to 115%. If the Amplifier is being overdriven (the RF output level is too high) the control system will automatically attenuate the RF input signal to the PA. It will continue attenuating this signal until the RF output is below 115% total power. If Reflected Power has been detected at the output of the transmitter, the unit will shut down for 4 seconds. This occurs 5 times – If the fault is clear the PA enables itself. If the fault still exists after 5 times, the PA disables the carrier for 10 minutes and cycles until the fault clears. During the disable time (10 minutes) the unit will still alarm with a High Reflected message on the front panel. Technalogix Ltd VI-6 TAVD-500 Transmitter The control system monitors the temperature of a specific location of the heat sync. If this temperature exceeds a threshold the control system will turn the RF output level down until this temperature level is reached. The RF output level will automatically be brought back when it is safe to do so.

Each heat sink has hollow fins, which help dissipate the heat from the amplifiers faster than a conventional serrated or corrugated fin. In addition to the cooling effects of the heat sinks, within the 500-watt power amplifier enclosure, there are six fans that each provide 170 cubic feet per minute (CFM) of air flow (into zero static pressure). There are three fans mounted at the front of the heat sink and three mounted at the back end of the heat sink. The fans are mounted side-by-side to produce the best cooling for the system and are operating in a push-pull configuration to assist with heat dissipation. The fans are a 24Vdc variety, so there are series dropping resistors to drop the higher power supply voltage down to a safe level. Technalogix Ltd VII-1 TAVD-500 Transmitter Section VIII - Installation This section contains installation recommendations, unpacking, inspection, and installation instructions for the power amplifier. We are sure that you are chomping at the bit to install your new system, so we recommend that you read the following sections very carefully. Building Recommendations The quality of the building is of great importance if you are to expect long life and continued performance from the power amplifier. The building must be clean, dry, temperature controlled and secure. Don’t forget to allow space in the building for any additional racks to house test equipment, a workbench area, line regulating transformers, ladders, equipment and parts storage, first aid kit, emergency generator if used, as well as heating and cooling devices that may be unique to your installation. A sloping roof will tend to develop leaks less rapidly. The building should be well roofed with good material. The cooling load will be lowered with reflective or light colored roofing material. Technalogix Ltd. VIII-1 TAVD-500 Transmitter Heating and Cooling Requirements The environment’s temperature will contribute greatly to the length of the power amplifier’s life. Technalogix recommends that the building’s filtered air intake must have capacity for all air-flow in the building plus an additional 20%. Keep the intake below the roofline to avoid intake of solar heated air. Please ensure that the intake and exhaust areas are on the same side of the building to avoid pressure differentials during windy conditions. Also, do not position intake near exhaust’s preheated air. If air conditioning is required to cool the shelter, discuss the situation with a qualified HVAC technician. Under average conditions, 12,000 BTUs will cool approximately 500 square feet to a comfortable level. The TAVD-5000 contains (3) DC ball bearing fans in each PA (push-pull configuration) and (2) fans in each of the combiner/filter and power supply enclosure. Technalogix Ltd. VIII-2 TAVD-500 Transmitter Electrical Service Recommendations Technalogix recommends that a qualified, licensed local electrician be consulted for the required electrical service. We suggest local electricians because: • The personnel knows the local codes • The personnel can be on site readily • You are apt to get better overall support if you give what business you can to local suppliers Technalogix recommends that proper AC line conditioning and surge suppression be provided on the primary AC input to the power amplifier. All electrical service should be installed with your national electrical code in your area, any applicable provincial or state codes, and good engineering practice. Special consideration should be given to lightning protection of all systems in view of the vulnerability of most transmitter or translator sites to lightning. Lightning arrestors are recommended in the service entrance. Straight and short grounds are recommended. The electrical serviced must be well grounded. Do not connect the unit to an open delta primary power supply, as voltage fluctuations could harm the unit. Branch your circuits. Do not allow your lights, your workbench plugs, and your transmitting or translating equipment to operate on one circuit breaker. Each transmitter or translator should have its own circuit breaker, so a failure in one does not shut off the whole installation. Technalogix Ltd. VIII-3 TAVD-500 Transmitter Antenna and Tower Recommendations Your preliminary engineering workgroup should establish your antenna and tower requirements, both for receiving and transmitting antennas. Construction of sturdy, high quality antenna/tower systems will pay off in terms of coverage of your service area, the overall quality and saleability of your radiated signal, and reduced maintenance expenses. Technalogix provides complete turnkey antenna systems if needed. If your site is serving as a translator, your receiving antenna should be in line of sight to the originating station all year round. The foliage will change with season. Transmitting antennas can enhance or seriously impair the transmitter/translator output. The selection, routing, and length of coaxial cable are extremely important in the installation. If there is a 3 dB line loss in the cable between your unit’s output and the transmitting antenna, a 1,000-watt unit will only deliver 500 watts to the antenna. Buy the best cable you can obtain, route it via the shortest way to the antenna, and keep it straight. Do not form it into sharp bends on its way. Do not use any more cable fittings for the installation than absolutely necessary. All cautions here apply equally to all coaxial cables in the system - input and output. Pay attention to radial ice accumulation when designing the transmission system. It is not uncommon for at least an inch of ice to build up on the tower and antenna. This in turn significantly increases the weight, cross section, and wind loading of the system. Attaching the transmission line to the tower is crucial to maintain a safe and reliable operation. Nylon wire ties and electrical tape will breakdown in the sunlight and ultimately fail, creating a potentially dangerous situation. It is important to use proper clamps and hoisting grips and also ensure that the transmission line is grounded to the tower in several locations. When high currents flow through the tower in the event of lightening strikes, some of that current will through the outer conductors of the transmission lines. Due to the resistance difference between the steel tower and copper transmission line, a significant voltage can be developed, often resulting in arcing between the outer jacket and outer conductor, thus pitting the conductor. Preventative maintenance is crucial in ensuring that safety is maintained. Specifically, check that transmission line grounds are tight and are not missing any hardware. Frequently inspect support clamps or spring hangers. Consider investing in an ice break, if you haven’t already done so, as shards of falling ice can damage the transmission line – and if it is going to happen, it will happen at an important time. Check the tower light photocells and conduit. The better-known tower manufacturers offer complete technical and safety documentation with their towers. Be sure that you have this information as it regards wind loading, guying, etc. The bestdesigned antenna system will function poorly if shortcuts and compromises are used during installation. Follow the manufacturer’s instructions exactly, along with any engineering data prepared for the site. Be absolutely safe and certain about this aspect as human lives may be at stake. Technalogix Ltd. VIII-4 TAVD-500 Transmitter Shelter Security The FCC requires that the transmitter or translator be secure from entry or control by unauthorized persons, and that any hazardous voltages or other dangers (including most tower bases) be protected by locks or fences as necessary to protect personnel and prevent unauthorized tampering or operation. Security of the building further implies that it be secure from wildlife. Use sturdy construction materials, including sheet metal if necessary. Holes around conduit, cable, and other similar entry points should be stuffed with steel wool and caulked to prevent entry of wildlife. Other features of security for your shelter may include its location with respect to the prevailing wind conditions. A location leeward of some natural topographical feature will prevent wind damage and snowdrifts. Check the soil runoff conditions that may slow or hasten wind or water erosion and other concerns that may be unique to your location. Technalogix Ltd. VIII-5 TAVD-500 Transmitter Unpacking and Inspection Check the outside of the container. Carefully open the container and remove the power amplifier. Retain all packing material that can be reassembled in the event that the equipment must be returned to the factory. Exercise care in handling equipment during inspection to prevent damage due to rough or careless handling. Visually inspect the enclosure of the power amplifier for damage that may have occurred during shipment. Check for evidence of water damage, bent or warped chassis, loose screws or nuts, or extraneous packing material in connectors or fan failures. Inspect all connectors for bent connector pins. If the equipment is damaged, a claim should be filed with the carrier once the extent of the damage is assessed. Technalogix cannot stress too strongly the importance of immediate careful inspection of the equipment and subsequent immediate filing of the necessary claims against the carrier if necessary. If possible, inspect the equipment in the presence of the delivery person. If the equipment is damaged, the carrier is your first area of recourse. If the equipment is damaged and must be returned to the factory, phone for a return authorization. Claims for loss or damage may not be withheld from any payment to Technalogix, nor may any payment due be withheld pending the outcome thereof. Technalogix cannot guarantee the carrier’s performance. Technalogix Ltd. VIII-6 TAVD-500 Transmitter Location and Function of Controls and Connectors (TAVD-500 Power Amplifier) The following illustration depicts the location of the connectors when installing the 500-watt power amplifier.

SELECT- Tactile button to select menu item, or to refresh the screen after it has timed out. RESET - Tactile button to reset microcontroller in control board. Also clears existing faults. The amplifier will come back on with the soft start feature. RF IN – RF input from modulator or processor. BNC connector, 50 ohm. RF OUT – 500-watt (rms) RF output. Connects to combiner/filter enclosure. N connector, 50 ohm. REMOTE PORT - Port to monitor and control the amplifier externally. See “ Monitor and Control” section for pin-out. Power amplifier has fault alarms only and filter/combiner has fault alarms and controls. Technalogix Ltd. VIII-8 TAVD-500 Transmitter Location and Function of Controls and Connectors (Filter Enclosure) The following illustration depicts the location of the connectors when installing the filter enclosure. Technalogix Ltd. VIII-9 TAVD-500 Transmitter RF IN - RF inputs (500-watts each) from the power amplifier. N female connector, 50 ohm. RF OUT – 500-watt (rms) RF output. Connects to inline wattmeter (not supplied) and antenna. 7/16”DIN female connector, 50 ohm. Technalogix Ltd. VIII-10 TAVD-500 Transmitter Initial Hook Up 1. Ensure that the antenna has been swept and has a return loss of greater than 20dB (VSWR = 1.2:1). This should be done before connecting the antenna cable to the transmitter output. 2. Check that your video source is present. 3. Place the transmitter/translator in its permanent location near a receptacle supplying required AC voltage. DO NOT APPLY AC POWER AND TURN ON POWER TO THE TRANSMITTER / TRANSLATOR AT THIS TIME SINCE THE RF OUTPUT MUST BE PROPERLY LOADED BEFORE OPERATION. 4. Place an appropriate AC power line protector, conditioner, and/or surge suppressor across the AC supply line. 5. Hook up the modulator or processor as shown in their respective manuals for a transmitter or translator. Do not connect the modulated signal from the RF OUT on the modulator or processor to RF IN on the power amplifiers at this time. Because of the characteristics of transistor devices, the RF drive should not be connected to the power amplifier until after the power supply and bias voltages are present and stable. 6. Ensure that modulator or processor RF output level is turned down as far as possible. 7. Hook up the PA out to the Filter in. 8. Connect the RF Output on the filter enclosure to the wattmeter directly (no cable in between) and then the output of the inline wattmeter to the transmitting antenna cable. 9. Plug power supply into AC mains (220 Vac, single phase). 10. Leave the AC rocker switch to “off” position. Technalogix Ltd. VIII-11 TAVD-500 Transmitter Section IX - Operating Procedure Assuming the previous installation instructions have been completed and cautions noted, and the TAVD-500 power amplifier is ready to receive a properly modulated video and audio signal, proceed with the following steps to place the system in operation. The TAVD-500 power amplifier has been factory aligned for channel frequency (per system specification), signal levels and optimum performance. IT IS HIGHLY RECOMMENDED THAT YOU RUN YOUR SYSTEM INTO A DUMMY LOAD BEFORE INSTALLING TO MAKE SURE THERE ARE NO DAMAGES CAUSED IN SHIPPING AND THE UNIT IS RUNNING PROPERLY 1. Do not apply RF drive signal to the power amplifier at this time. 2. Verify that all control and RF cables are tight and properly seated in or on the mating connector. 3. Plug the modulator or processor into AC mains. 4. With the PA output loaded, plug the 3U power supply enclosure into 220V AC mains. 5. Switch AC rocker switch to “ON” position. 6. Verify that the power amplifier fans are all on. 7. Ensure that the modulator/processor is turned on and set up according to its instructions. Depress the POWER tactile button to turn the unit on. 8. The internal soft start circuitry will turn the bias voltages off until the power supply to the amplifier pallets is fully stable. The message on the LCD indicates when the soft start is running. Once complete, the Forward and Reflected Power and Power Supply readings will appear on the LCD in the filter and power amplifier enclosures. 9. After the soft start is complete, apply the RF drive signal (which still should be turned down) between the modulator or processor and the power amplifier RF In. This ensures that the RF drive signal is applied only after the power supply is stable and the bias voltages are applied to the amplifier. Technalogix Ltd IX-1 TAVD-500 Transmitter 10. The TAVD-500 LCDs show the user the present status of the amplifiers. Adjust RF output power to desired level (see Important RF Power Notice in previous section). Verify that the FWD Power reads 400 to 500 Watts on the PA enclosure. The output power level can be adjusted using the modulator or processor’s RF output level adjust. Keep in mind that the system will shut down should the forward RF output power level be exceeded. 11. Ideally, the RFL Power should read zero. However, should a high VSWR be detected, the system will automatically shut down and cycle as previously described. 12. Verify that the power supply reads approximately 30 Volts DC (see supplied final inspection sheet for factory settings of power supply levels) on the LCD of the power amplifier. 13. Look at the transmitted output using a suitable monitor. The picture and sound quality should be clean and sharp. If the output picture and sound quality is unsatisfactory, check the input signals, connections to the antenna system, antenna and transmission line VSWR, and the physical condition of the antenna. If reception problems are encountered, and the quality of transmission is satisfactory, the difficulty is often with the receiving antenna or with obstructions in the path between the transmitter/translator and receiver. Technalogix Ltd IX-2 TAVD-500 Transmitter Section X – Maintenance and Troubleshooting Periodic Maintenance If your unit employs a filter on the air inlet for the fans, the filter should be cleaned every 30 days. If the equipment is operated in a severe dust environment, the filters on the inlet fan may need to be cleaned more regularly. Turn the system off and unplug all of the AC inlet cords. The filter can be lifted off the fan and cleaned using an air compressor at low pressure. While the filter is out, clean the fan blades themselves with a small brush. The fans themselves do not need lubrication. The interior of the cabinets should be cleaned and inspected annually. Turn the system off and unplug all of the AC inlet cords. Remove the top lid by unscrewing the 6-32 machine screws. Use extreme caution when working near the AC input terminal. The power amplifier and power supply store hazardous capacitances and voltages. Using either compressed air or a brush with soft bristles, loosen accumulated dust and dirt and then vacuum the interior of the cabinet. Complete a visual inspection of the interior, making sure there are no loose connections or discolorations on any components from heat. Nothing inside the power amplifier enclosure exceeds a temperature that is not comfortable to the touch under normal operating conditions, so any signs of discoloration indicate potential damage. All modular components inside the enclosure are attached to aluminium mounting plates for easy removal and replacement. Ensure that plates are secured and the mounting hardware is tight. Technalogix Ltd X-1 TAVD-500 Transmitter Troubleshooting The first and most important aspect of troubleshooting anything is to be systematic. Note where you have looked and what you found. Look first for the obvious. • Make a physical inspection of the entire facility. Are all necessary connections properly made? Do you see any signs of obvious damage within the equipment? • Is the AC power ‘ON’ to the site and the equipment? (Check fuses and circuit breakers if necessary.) • Are all the switches in the correct operating position? • Is the input signal present? • Check LCD readings for presence of forward and reflected power and 31 V DC supply levels. The above is an aid in determining the fault if some aspect of the system is not operating. The following table deals with quality of operation: Symptom Horizontal bars in picture (may roll either way depending on phase) Diagonal lines in picture Technalogix Ltd Possible Fault AC grounding / AC interference Interference X-2 Correction Install EMI/RFI filter in AC line Ensure modulator/processor and power amplifier share a common ground Install EMI/RFI filter in AC line Determine source and frequency of interfering signal (spectrum analyzer may be required) TAVD-500 Transmitter Symptom High reflected power Technalogix Ltd Possible Fault Correction Incorrect load Ensure amplifier connected to transmission line Ensure correct antenna impedance (50 ohms) Check antenna tuning and VSWR. Verify correct cable for transmission line length Check all cables for visible damage (kinks, nicks or cuts) Check all connectors for poor connections, water or corrosion Check alignment of antenna Check for physical damage of antenna, including ice build-up X-3 TAVD-500 Transmitter Thank you for choosing Technalogix Ltd.
