17AMPLIFIER CONTROLOMICR O PR O CESSO R CO N TROLLE D SYS TEMRS232PO W ER CODE: APG012B TITLE: AMPLIFIER CONTROL REV: 0 DATE: 25/11/02
181.1 FUNCTIONSThe 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 graphicdisplay all the checked parameters. The number of the Slaves changes depending on the output power ofthe amplifier. The communication between Master and Slaves is made via I2Cbus standard. The Masterboard reads the overall parameters of the equipment (forward and reflected power and unbalancing),polls (interrogates in sequence) the local boards, shows on the display the values requested by the userand indicates alarm conditions, if any. Besides it realizes a serial data interface to an external systemable to analyse the working parameters of the equipment, using the RS232 and RS485 communicationprotocols.At start-up, the display of the Amplifier Control shows an informational message concerning the equip-ment and the firmware version.The main menu has: a list of the amplifier modules, the measure of some parameters of the powers in antenna,a window with icons to show the alarm status and some general information, that is date, time, temperatureinside the module and, for FM equipment, transmission frequency.In the Amplifier List, next to each module, you can find the following symbols:AMPLIFIER CONTROLif 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 ONOMICR O PRO CE SSO R CO N TROLL E D SYS TEMRS232POW ER
19The UP and DOWN arrow keys allow to select one of the slave or the alarm list; the RET key is used toconfirm the selection.By selecting one of the slaves, it is possible to see all the parameters of that amplifier module, that is voltagesand currents of the power supply, forward and reflected power, temperature and, for some amplifiers,unbalancing powers. The UP and DOWN keys allow to scroll the local measures of all the slaves. The ESCkey is used to go back to the main menu.By selecting the Alarm List, two pages listing the latest 20 alarms saved are shown. Each line in these pagesincludes the progressive number of the alarm, starting with the most recent, the number of the module in whichthe alarm occurred (the indication “AC” means that the alarm occurred in the Amplifier Control module), theparameter in alarm and the date and time of the alarm. The saved alarm can be deleted by keeping simultane-ously pressed the UP and DOWN keys. The ESC key is used to go back to the main menu.In the main menu there is the Alarm Status Window:displays the status of the INTERLOCK, in case of alarm this icon blinks and the buzzer rings.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 thePIN is left floating, an alarm is detected;shows the status of the FANS: works normally;in case of alarm this icon blinks and the buzzer rings;this icon blinks in case of ALARM.If one of the parameters of a Slave or any of the ones directly checked by the Master is alarmed, thegeneral alarm LED and the alarm icon blink until the Alarm List is checked to see the type of alarmoccurred.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.
20In case the amplifiers are communicating but switched off, or they are not communicating and the INTER-LOCK alarm contact is open, a WARNING condition occurs: buzzer on and blinking ALARM LED on thefront panel; 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 or not the amplifiers. In fact, ifthe DIP-switch n. 2 (see mounting plan BOTTOM - SCH0109BR0) is set to OFF before turning on thetransmitter, the amplifiers will be switched off after a FAN alarm occurs, while it will be kept on if the switchis set to ON. The DIP-switch n. 3 has the same effect for what concerns the Interlock alarm.1.2 PROGRAMMING MODETo access the “Programming Mode”, press simultaneously the ESC and RET keys. The “Setting Time”menu or the “Setting Frequency” menu can be selected by using the arrow keys, while the RET key confirmsthe choice. While this menu is open, no alarm will be signalled until the return to the main menu. If no key ispressed for about 50 seconds, the main menu is automatically displayed.The Setting Time menu allows to set the following functions: hour, minute, day, month and year. The selectedparameter blinks and can be modified with the arrow keys; the RET key confirms the changes, while the ESCkey cancels them.The “Setting Frequency” menu appears only in the FM amplifiers. To visualize the power emitted by theantenna correctly, set the frequency nearest to the working frequency of the transmitter in the frequencyprogramming menu. The selected parameter blinks and can be modified with the arrow keys; the RET keyconfirms the changes, while the ESC key cancels them.1.3 SETTINGSet the RS232-RS485 mode on the SCH0109BR0 Control board:RS232 MODE - DIP-switch n. 1 set to ON before turning on the transmitter: the RS232 mode allows adirect access to the equipment via PC and a remote access via modem or switched telephone line.RS485 MODE - DIP-switch n. 1 set to OFF before turning on the transmitter. ThevRS485 mode allows aremote access to the equipment via modem over switched telephone line or GSM network. It allows theconnection to the Remote Control System, designed to monitor several apparatuses located at the same site.- FWD Power calibrationDisconnect the antenna and connect a wattmeter to the antenna connector. Give power to the amplifier untilyou will read on the wattmeter a value corresponding to the equipment nominal power. Then turn the trimmer
21A (see mounting plan BOTTOM - SCH0109BR0, it is a variable resistor used to adjust the A analog inputmeasure) until you read approximately the same FWD power value on the display.- REF Power calibrationDisconnect the antenna and connect a wattmeter to the antenna connector. Connect the Forward powermonitoring cable to the Reflected power input connector. Give power to the amplifier until you will read on thewattmeter a value corresponding to 10% of the equipment nominal power. Then turn the trimmer B (seemounting plan BOTTOM - SCH0109BR0, it is a variable resistor used to adjust the B analog input measure)until you read approximately the same REF power value on the display.- UNB CalibrationConnect a wattmeter before the dummy load. Give power to the amplifier then turn off one slavemodule: you will read an amount of unbalancing power on the wattmeter. Turn the trimmer C (see mountingplan BOTTOM - SCH0109BR0, it is a variable resistor used to adjust the C analog input measure) until youread approximately the same UNB power value on the display.1.4 REMOTE CONTROLIt is possible to remotely control the apparatus, thus to monitor the parameters shown on the display of theAmplifier Control and check the status of the transmitter. This is done through RS232 and RS485 standardserial communication, digital and analog inputs through the DB25 telemetering connector on the rear panel ofthe Amplifier Control.The pins n. 1 and n. 14 of this connector are used to receive the ON (pin n. 1) and OFF (pin n. 14)commands, both impulsive and stationary. The digital level on these contacts is usually high, becoming lowwhen the remote control is active. When a remote command to turn off the amplifiers is received while thetransmitters is ON, the LED ON of the frontal panel blinks and the REMOTE LED lights up.

561.1 DESCRIPTIONThe AUTV/1000LD is an amplifier operating into Band IV-V for common amplification process of the Visionand Sound carriers.The amplifier has been designed to offer to the customer high performances, high reliability and greater simplicityin his operation and maintenance procedures.The amplifiers modules employ all solid state LDMOS technology in order to obtain high gain, wide-bandperformances, very good linearity, reliability and high efficiency.The equipment design allows the soft degradation (RF power loss) for several transistor faulty: in fact theoutput combiner uses RF power resistors for unbalancing power dissipation.The amplifier is put in a 20U rack just ready for a double driver use. Inside the rack there is also the outputband-pass filter.AUTV/1000LDLDMOS - UHF TV AMPLIFIER
