11LDMOS - UHF TV AMPLIFIERAUTV/3500LDUsers manual
12INTRODUCTIONThe AUTV/3500LD belongs to the High Power UHF products family of Television Transmitters fully in solidstate technology.The AUTV/3500LD series represents the 3,5kW TV Transmitters operating in the IV/V Band for Commonamplification process (separate amplification available) of the Vision and Sound carriers. This Transmittersfamily has been designed to offer to the customer high performances, high reliability and greater simplicity intheir operation and maintenance procedures.The Vision and Sound signal processing is provided for all TV Standards and all types of Audio applications(Mono & Dual sound - NICAM) together with colour systems such as PAL - NTSC - SECAM. Thanks tothe amplitude and phase pre-correction circuit, it is possible to cancel the distortions in the output stage, thuscutting down the operating costs. The RF transposition in the driver is carried out by a synthesizer with variouspossibilities of accuracy and stability as well as precision offset locked by internal or external frequencyreference.The RF amplifier is made up by three RF modules installed in a power rack, the modules are dedicated for theVision and Sound carriers common amplification. The amplifiers employ solid state LDMOS technology inorder to obtain wide band, reliability, and high efficiency. Each RF module has a built-in switching-modepower supply unit, self-protected against overcurrents and overvoltages, as well as overtemperature andVSWR for RF parameters. The cooling system is fully contained into the transmitter. The control unit providesfull management of the transmitter without the presence of the operator, the system includes a central controllerand several peripheral units installed in each RF module and rack. The control device includes a fault findingsystem to detect equipment malfunctions and locate the faulty subassembly which needs to be replaced. Theinterlock circuit is independent on the software and remains always operational whether computer control ispresent or not. The operator interface is made by a high resolution LCD graphic display and a simple keyboard,the menu is very friendly and easy to use.The Control Unit can be fully controlled in REMOTE mode via link or via modem in RS232 or other interface.The equipment design allows the soft degradation (RF power loss) for several transistors faults.AUTV/3500LDLDMOS - UHF TV SOLID STATE AMPLIFIER

161.1 CONTROL SYSTEM OVERVIEWThe control system is made up by some Slave boards, which check locally the amplifier modules, and aMaster board to monitor the status of the Slave boards in each module and show on a graphic display allthe checked parameters.The number of the Slaves changes depending on the output power of the amplifier. The communicationbetween Master and Slaves is made via RS485 standard. The Master board reads the overall parameters ofthe equipment (Forward and Reflected power and Unbalancing), polls (interrogaes in sequence) the localboards, shows on the display the values requested by the user, indicates alarm conditions, if any, and allowsto change some of the operating parameters of the apparatus. Besides it realizes a serial data interface to anexternal system able to analyse the working parameters of the equipment, using the RS232 and RS485communication protocols.1.2 FUNCTIONSAt start-up, the display of Amplifier Control module shows an informational message concerning the equipmentand its firmware version.- Main menuThe main menu has: a list of the amplifier modules, the measure of some parameters of the power in antenna,a window with icons to show the alarm status (Alarm Status Window) and some general information, that isdate, time, temperature inside the module and, for FM equipment, transmission frequency.The following picture is an exact representation of the main menu screen.AMPLIFIER CONTROLOMICROPROCESSOR CONTROLLED SYSTEMRS2 3 2
17if the communication with the slave is correct and thenif the communication with the slave is interruptedONif the amplifier module is OFFOFFif the amplifier module is ONIn the Amplifier List, next to each module, the following symbols can be found:The UP and DOWN arrow keys allow to select one of the slave, the alarm list, or a menu allowing to changesome settings of the control module and the apparatus; the RET key is used to confirm the selection.In the main and slave menu the Alarm Status Window (which position is indicated by an arrow in the picturebelow) is shown: the gate symbol displays the status of the INTERLOCK, in case of alarm this icon blinksand the buzzer ringgs.The INTERLOCK signal is a control available to the user to manage an ON/OFF sensor.When the relevant PIN is grounded, the Master board does not signal any alarm, as soon as the PIN is leftfloating, an alarm is detected; the rotating screw symbol shows that the FANS work normally; in case of alarmthis icon blinks and the buzzer rings; the bell symbol appears in case of alarm detected by the control moduleor the amplifier. It blinks if the alarm condition is terminated and the alarm itself can be displayed in the AlarmList.If one of the parameters of a Slave or any of the ones directly checked by the Master is alarmed, the general
18Note that no numerical value is shown for amplifiers which are not communicating with the control module.alarm LED and the alarm icon blink until the Alarm List is checked to see the type of alarm occurred.Besides, if an alarm for any of the powers of the signals in antenna occurs, the relevant measure in theAntenna window of the display and the relevant LED on the front panel of the Master module blink until themeasure decreases below the threshold level, determined by the nominal power of the amplifier.If the slave modules are working and an INTERLOCK or FANS alarm occurs, aside from the indicationexplained above, the amplifiers are switched off. This happens immediately after an INTERLOCK alarm, orabout 7 seconds after a FANS alarm is detected.In case the amplifiers are communicating but switched off, or they are not communicating and the INTERLOCKalarm contact is open, a WARNING condition occurs: buzzer on and blinking ALARM LED on the frontpanel; while if it is the FANS alarm contact to be open, the icon of the alarm appears in the box.Further to any of these two alarms it is possible to choose whether to turn off the amplifiers or not. In fact,there is a submenu of the Settings menu which allows to choose whether to turn off the amplifiers connectedto the control module as a consequence of an INTERLOCK and FAN alarm.- Slave menuBy selecting one of the slaves, it is possible to see all the parameters of that amplifier module in two pages. Thefirst one shows voltages and currents Power Supply, the second one shows RF Powers: forward and reflectedpower, temperature and, for some amplifiers, unbalancing and input power. The UP and DOWN keys allowto scroll the local measures of all the slaves, page by page. The ESC key is used to go back to the main menu.The following pictures show the menu screen of one amplifier.
19- Alarm ListBy selecting the Alarm List, 26 pages listing the latest 130 alarms saved are shown. Each page shows 5alarms, each contained in a box providing the following information: progressive number of the alarm, startingwith the most recent; number of the module in which the alarm occurred, following the Blk. Message (theindication AC means that the alarm occurred in the Amplifier Control module); parameter in alarm, date andtime of the alarm. Next to the parameter showing the alarm type there may be a bell symbol. In case it is nothere, the alarm event has been communicated by an amplifier connected to the control module. These eventsare different and on option of the Settings menu allows to choose whether they are displayed or not in thealarm list.The saved alarm can be deleted by keeping simultaneously pressed the UP and DOWN keys. The ESC keyis used to go back to the main menu. The picture shows a page of the list, containing both alarms and generalevents.1.3 PROGRAMMING MODEThe Settings menu gives access to programming mode. As shown below, the menu offers a list of settings nextto a window showing the default parameter set, or the one selected previously, when the pointer is moved onthe relevant options.The menu under the cursor is accessed by pressing the RET key. This is shown by the Enabled Menu. Once

A message in the main menu screenconfirms current choice.It is possible to remotely control the apparatus, thus to monitor the parametersshown on the display of Amplifier Control module and check the status of thetransmitter.This is done through RS232 or RS485 standard serial communication, digitaland analog inputs through the DB25 telemetering connector on the rear panelof the Amplifier Control module.If the Local mode is set in this menu, the control module and the apparatuscan only be controlled locally, and a remote command is ignored. If Remoteis set instead, the REMOTE LED on the front panel of the module lights upafter going back to the main screen. From then on, incoming remote commandsfrom either the serial port or the telemeasuring connector on the rear panelare handled (Note 1).Clock / DateFWD Read ModeRemote Controlthe menu is accessed, it is possible to change the value of the displayed fields or select a function by means ofthe arrow keys. The RET key is used to confirm the selection (an acoustic signal should be heard). The ESCkey (or no key pressed for more than 7 seconds) sends back to the setting list. Pressing it again (or pressingno key for more than 10 seconds) brings back to the main menu.Every selection made in the Settings menu is stored into the EEPROM until it is changed again, this allows toremember the settings status after an equipment reset.

582.1 OPERATING ENVIRONMENTYou can install the apparatus in a standard component rack or on a suitable surface such as a bench or desk.In any case, the area should be as clean and well-ventilated as possible. Always allow for at least 2 cm ofclearance under the unit for ventilation. If you set the apparatus on a flat surface, install spacers on the bottomcover plate. If you install the apparatus in a rack, provide adequate clearance above and below. Do not locatethe apparatus directly above a hot piece of equipment.2.2 PRELIMINARY OPERATIONSCorrect installation of the equipment is important for maximum performance and reliability. Antenna and earthconnections must be installed with the greatest care. The equipment adjustment isnt need, because the unit iscompletely adjusted by our technical staff. This is the installation procedure:1. connect the power supply cable of the exciter to the auxiliary socket on the rear panel of the amplifier;2. connect the power supply cable of the amplifier to the electric network (230VAC). If there is the IsolatorTransformer, the amplifier is provided with cable and plug;3. connect the exciter / antenna cables respectively to the RF IN and RF OUT on the rear panel of theamplifier.WARNING!!!FOR ELECTRICAL SAFETY REASONS AND IN ORDER TO KEEPTHE APPARATUS SAFE, THE GROUND TERMINAL OF THEAPPARATUS MUST BE CONNECTED TO THE EXISTING GROUND-ING SYSTEM AND NOT BY USING THE SHIELD OF THE OUTPUTCOAXIAL CABLE.231Three-Phase cablingMonophase cabling
59When the apparatus is put within a combined system it is directly connected to the input splitting and outputcombining systems.Before fully powering the apparatus, check that the output connections of the coaxial cable to the antennasystem are working.In order to this it is possible to check the indication of the reflected power at low power levels. Only if theSWR indication on the display is 0, the output power can be slowly increased. At maximum output power,some watts might be shown as reflected power.2.3 TELEMEASURING SOCKET CONNECTIONSDB9 Socket2.4 RS232, RS485 AND AGC SOCKET CONNECTIONSPIN N° SIGNAL TYPE IN / OUT FUNCTION1 Analog Output FWD Power2 Analog Output REF Power3 Digital Output Temperature4 Digital Input Interlock5GND - -6 - 7 Digital Output Free contact (closed when alarm)8 Digital Input 0V = ON5V = Normal9 Digital Input 0V = OFF5V = NormalPIN 123456789FUNCTIONS -TxDRxD-GND----RS232 - DB9 SocketPIN 123456789FUNCTIONS -Rx-Rx+5VGND-Tx-Tx+-RS485 - DB9 Socket

643.1 OPERATIONAt startup, after initial image, the display shows the main screen with the RF powers as in Figure 1:The user may turn on and off the amplifier by means of the switch on the front panel. The control board turnson all the power supplies, the exciter (if any), and internal cooling fans. While the amplifier is working, themicro-controller monitors continuously the most important parameters: power supply voltages, absorbedcurrents, high power zone temperature, forward and reflected powers, unbalances (if any). Each measure isassociated to a maximum threshold beyond which the amplifier is immediately put in protection status byturning off one or more power supply, depending on the failed block. In order to prevent a temporary problemto trigger a definitive protection status, the failed block is turned on again, after some seconds, for up to fivetimes. If it goes beyond the protection threshold for more than five times, it is declared as FAILED and it willno longer be turned on. In this case, the amplifier will have to be turned off manually by means of the switch onthe front panel, then turned on again after performing the needed maintenance.On the front panel there are also three LEDs labelled ON, REMOTE and ALARM. Their meanings areexplained in Table 1.Figure 1: Main screenTable 1: Meanings of the three LEDs on the front panel1 Screenshots in this manual are indicative, so they can be different from those on your equipment.LED COLOUR MEANING MEANING WHEN BLINKINGON Green The amplifier is onThe amplifier has been turned onlocally but it has been turned off byremoteREMOTE Yellow Remote control isenabled It never bli nksALARM Red An alarm is present It never blinks
653.2 DISPLAYThe control board is provided with a modern pixels graphic display with blue background. Normally it alwaysshows a title bar (on the top line) and a status bar (on the bottom line).The title bar, see Figure 2, shows the name of the amplifier (TV Amplifier) and the current time. If the amplifieris a single unit coupled externally with other units in a high power transmitter, the title bar shows the amplifiernumber (slave address) too.Figure 2: Title barFigure 3: Status BarThe status bar (Figure 3) indicates the forward and reflected powers and the temperature. It also contains twosymbols for the interlock (lock) and the alarm (bell).The bell symbol is continuously displayed in case of alarm. It blinks if there has been an alarm which has endedbut has not yet been seen by the user. It stops blinking once the Log has been checked.The interlock symbol is displayed only when this function is enabled. It may be either a close lock, as in Figure3, when there is no alarm (interlock chain closed) or an open lock in case of alarm (interlock chain open).Since the status bar is always showed on the display, regardless of the screen, the user may monitor at anytime the most important parameters and the presence of alarms while moving between different screens.3.3 MENUSThe user may see or modify locally some configuration parameters using the four buttons on the front panel.All screens areorganized in a hierarchical menus and the user may move between them in a simple and intuitiveway.To see the menu its sufficient to press the ESC key (see Figure 4).
66Figure 4: Main menuThe display only shows three items at a time: all the items can be scrolled by the UP and DOWN arrow keys.Any item can be chosen by selecting it and pressing the RET key. Menu entries with an arrow on the right open sub-menus when chosen. Thus there is a hierarchical structure as in Figure 5. To go back from a sub-menu to the previous menu, press the ESC key. If the ESC key is pressed in the main menu, the RF powersscreen is accessed.Figure 5: Hierarchical menu structureAll menu items are described in detail below.
67- RF PowersThis is the main screen showing the RF powers of the amplifier: forward power, reflected power, unbalances,if any. For forward power a level bar is displayed. See an example in Figure 1.- Power SupplyThis screen shows all the signals coming from two power supply. To check the next (previous) power supplypress the UP (DOWN) key. For each power supply, the voltage, the absorbed current and the status (ON orOFF) are shown.Figure 6: Power supply screen- Log/AlarmsThe control board is provided with an external EEPROM and a clock. Any alarm or switching event with thetime at which it occurred is saved in the EEPROM. The Log/Alarms sub-menu allows to manage this log.It is possible to see the events stored in the log by selecting Log/Alarms View Log/Alarms. All eventscan be scrolled by pressing the UP and DOWN keys. For example, the event shown in Figure 7 is the turningon of the amplifier by means of the local switch. For every event/alarm a short description and the date andtime at which it occurred is displayed.Figure 7: Event stored in the log
68In case of alarm, the value of the measure which caused the alarm is saved into the log. In case of alarm stillexisting after five turning-on attempts, the parameter is marked as FAILED. Table 2 is the list of all the eventswhich can be logged.Table 2: Events managed and logged by the control boardThe log may be completely deleted by selecting Log/Alarms Clear Log/Alarms.Amplifier can store in the log details about alarms and generic events. You can change this behaviour selectingLog/Alarms Log/Mode menu item.- Working TimerThe control board has a working timer which is always enabled while the amplifier is working (i. e. there is atleast one power supply working). The menu entry Working Timer View Timer allows to check the hoursfor which the timer has been enabled. Working Timer Timer Reset resets the timer.- ThresholdsThis is a screen showing the alarm threshold of each signals monitored by the control board. The list can bescrolled by means of the UP and DOWN keys.EVENT DESCRIPTIONLocal ON Amplifier turned on by means of the local switchLocal OFF Amplifier turned off by means of the local switchRemote ON Amplifier turned on remotelyRemote OFF Amplifier turned off remotelyInterlock open Interlock chain openInterlock closed Interlock chain closedPower Supply ON Power supply onFwd Pwr xxxxW Alarm for forward powerRef Pwr xxxxW Alarm for reflected powerUnbY xxxxW Unbalancing alarmV1 xx.xV Power supply voltage alarmI1 xx.xA Power supply current alarm
69- RMS/PeakThe control board can monitor both the RMS and peak powers, the first used in digital systems. The menuentry Settings RMS/Peak allows to choose the power to be displayed and monitored. This menu ispresent only in certain amplifiers.- Date/TimeThis screen allows to set the current date and time. The setting is changed by pressing the arrow keys, thenpressing the RET key to move to the following value and eventually save the changes. To go back to theprevious menu and discard any change made, press the ESC key. Figure 8 shows an example of this screen.Figure 8: Date and time setting screen- DisplayThe menu entry Settings Display allows to change some settings of the display, such has back light,contrast and screensaver. The back light and the contrast are set by means of the UP and DOWN arrowkeys. The changes made are saved by pressing the RET key or discarded pressing the ESC key. Figure 9shows an example of this screen.With Settings Display Screensaver you can set an interval time after which display backlight isturned off. When display backlight is off, press any key to switch it on.Figure 9: Display contrast setting screen
70- Frequency (only for some Amplifiers)The forward and reflected RF powers is measured by means of a directional coupler. In order to compensatefor the effect due to the sampling made by the coupler, it is possible to set the frequency by menu entrySettings Frequency. The setting can be changed by pressing the arrow keys. The changes made aresaved by pressing the RET key or discarded pressing the ESC key. Set the video carrier frequency.- Slave AddressThe amplifier may be used either in stand-alone mode or as a slave of a master in a high power multiple unitstransmitter. In the latter case an unique address for each amplifier has to be specified, in order for all of themto communicate with the master on the same RS485 bus. The menu entry Settings Slave Addressallows to choose the stand-alone mode or set a slave address by means of the UP and DOWN arrow keys.The changes made are saved by pressing the RET key or discarded pressing the ESC key. An example of thisscreen is shown in Figure 10.Figure 10:Slave address setting screen- RemoteThe amplifier may be controlled either locally, by means of the keys and display, or remotely. There are threepossibilities for remote control:- using a direct serial connection between amplifier RS232 connector and a PC RS232;- using the remote control device manufactured by Elettronika S.r.l. (RCU), on the RS485;- using a general-purpose control system connected to telemeasures.You can enable / disable remote control choosing menu item Settings Remote. When remote controlis enabled, the yellow REMOTE LED on the front panel is lit.- InterlockOne of the pins of the telemeasure connector, located on the rear panel, is used for the interlock alarm. It is aninput line which turns off the amplifier in case of alarm. The interlock check can be enabled or disabled using
71menu item Settings Interlock. When it is enabled, the status bar shows the lock symbol (see Figure 3),which is close if the interlock chain is closed (no alarm) or open if it is open (alarm).- Firmware ReleaseThe menu entry Settings Firmware Release allows to display the firmware version number and thehardware release of the amplifier.- Serial NumberThe menu entry Settings Serial Number allows to display the serial number of the apparatus.
