7 / 28User Manual Rev. 1.5L - 14/10/02

4. General DescriptionRVR Elettronica's PJ500M-C/LCD is a 19" rack-mountable broadband MOSFETRF power amplifier. It works without adjustments on the whole 87.5 - 108 MHz FMband, and its power output is 500 W with a drive level of about 10 W.

The RF power section makes use of two modules, able to deliver more than 300W each.

The power supply is a switching mode one, and a soft-start circuit is included tominimize the transformer's current spikes when the device is switched on.

The PJ500M-C/LCD is controlled by a microprocessor system including a LCDdisplay, implementing the following functions: measurement and display of the amplifier's working parameters activation and deactivation of the RF power output protection of the amplifier against dangerous sistuations like exceeding output

power or swr, overdrive or overtemperature detection of user-settable attention thresholds (e.g. output power being below

a certain value), that are made externally available using the "telemetry"connector

communication with external devices

The amplifier gives the option for an external 24 V dc power supply: this willautomatically be used to supply the CPU section in case the mains power goesoff, allowing to interact with the device even in such case.

The user can navigate through the menu system using four buttons, ESC, moveLEFT/UP, move RIGHT/DOWN and ENTER. Another button is used to reset thealarms that possibly arose.

Five LEDs on the front panel of the amplifier show the current status of the machine:ON/OFF, WAIT, FAULT, LOCAL and FOLDBACK

A switch allows to select the LOCAL or REMOTE mode. LOCAL mode allows tocontrol the machine using the buttons on the front panel, while remote control (that isusing the telemetry connector) is disable. In REMOTE mode, buttonson the panelcan be used only to read parameters, but they can be changed only remotly.

The PJ500M-C includes the Automatic Gain Control feature, that will can be used tofix the RF output power of the amplifier to the desired value so that environmentalfactors (e.g. temperature) or settings (frequency change) dont impact onto thedelivered RF power. The AGC function can be seen as an add-on, meaning that itcan be exploited or not depending on the user preferences. More informations aboutthis are given in the manual.

PJ500M-C

8 / 28 User ManualRev. 1.5L - 14/10/02

Different working parameters are made available for the user on the telemetryconnector, as voltage levels that are proportional to the value of the parameterunder consideration.

A built-in low-pass filter keeps the harmonic emission level below the CCIR andFCC permitted levels.

5. Installation and UseThis chapter is intended to summarize the necessary point for the installation of thedevice. In case any of the arguments is unclear, for example when you use it for thefirst time, please read carefully the whole manual.

5.1 Preparation

Unpack the amplifier and before any other operation check the unit for any shippingdamage and check that all the controls and connectors on the front and rearpanels are in good conditions.

Check the mains voltage selector on the rear panel: the position of the jumpers tochose between 220 and 110 mains voltage is indicated on the panel.

Check also the presence and the integrity of the fuses. The required value for thefuses are: RF MODULE 25 A 10X38 A.C. LINE 10 A 6,3X32 AUX OUT A.C. LINE 4 A 6,3X32

Verify that the mains switch is in the OFF position.

Connect to the RF input the RF output of a suitable exciter (e.g. RVR ElettronicaPTX30) using a N-connectors terminated cable; the exciter shall be set for minimumpower and OFF.

Turn the Power Adj. multiturn trimmer on the front panel completely clockwise. Thisoperation disables the intervention of the AGC

Link one of the ALARMS/INTERLOCK connectors to the INTERLOCK connector ofthe exciter, if available (it is, in RVR Elettronica exciters).

Connect The RF output to the antenna cable or to a suitable dummy load.

Finally, connect a proper cable to the amplifier's mains input.ATTENTION: the cable has to be disconnected from the mains outlet.

After the cable has been safely connected to the amplifiers mains plug, it is possibleto plug it into the mains outlet.

The amplifier shall be mounted in one rack that contain a anti-strap device to notexpose accidentally the mains conductors.

PJ500M-C

10 / 28 User ManualRev. 1.5L - 14/10/02

ATTENTION: It is essential that the unit is properly earthed to ensure both thesafety of operation as well as the correct working of the equipment.

5.2 Operation

Switch the amplifier on and verify the green "ON" LED being lit. The LCD displaywill indicate a first screen of presentation of the amplifier and next it will switch toa screen indicating the forward and reflected power.

Switch the exciter on (to minimum power level) and wait for it to lock on the workingfrequency. When the locked condition will be reached, progressively increase itsoutput power, while controlling the amplifier's display. Keep increasing the exciteroutput until the amplifier reaches the desired level, at most 500W. (Please notethat, as result of the digitalization of measurements, it could happen that thedisplayed value is not exactly 500W, but a value comprised between 495 and505; this is perfectly normal.)

At this point, the transmitter is set for its nominal power, but the built-in AGCfunction is not controlling the output power of the amplifier. Changes in theexciters power, or in the environmental conditions could reduce the RF powergenerated by the amplifier.

To activate the AGC, increase the exciters output level up to 10 W (the FWDpower of the amplifier will reach 540W or more, but its internal limiter will makeshure that no harm will be caused to the machine). The exciters power can alsobe measured as the amplifiers input power in the Power Menu, as describedlater in the manual. Now turn counterclockwise the PWR Adj. trimmer on the frontpanel of the PJ500M-C observing the reduction in the delivered power of theamplifier, until the desired level is reached.

If the amplifier has to be used at a lower power level, two ways can be followed: If the power reduction will be temporary (e.g. for tests), simply reduce the

exciters power until the required level is reached If the power reduction will be permanent (that is to have lower transmitted

power by the station), first disable the AGC function turning clockwise thePWR Adj. trimmer of the amplifier. Than reduce the exciters powerproportionally to the wanted reduction in the output power of the transmitter.Finally turn the PWR Adj. trimmer counterclockwise until the desired outputpower is reached

At this point, it is possible for the user to verify all the working parameters of theamplifier using the management software.

PJ500M-C

11 / 28User Manual Rev. 1.5L - 14/10/02

Normally, the device doesnt require any human supervision for its normal operation.If any alarm condition arise, these are automatically managed by the embeddedprotection system, and notified to the user with the LEDs on the panel or via messageson the LCD display.

5.3 Software

This chapter describes in which mode microprocessor system controls the amplifier,and how the user can interact with it.

Note that the user can give commands to the device only when it's set in LOCALmode using the switch [13] of Figure 1. Otherwise, the user will only be allowed toread the parameters, but not to change any of them.

The flow diagram in figure 3 gives an overall view of the use interface of thesoftware.

At power on, the LCD display will show the following presentation screen, indicatingthe name of the device and the indication of the switch-on power limiter device namedSoft Start:

To enter into another menu, just select the corresponding name (that will be indicatedby a flashing underscore) with the LEFT and RIGHT buttons, and then push ENTER.

Note that some of the parameters that are measured and can be read may be, insome circumstances, not available. This situation mostly arises when, for physicalreasons, the measured values are not significant to be used in the control software.

When the value for a parameter is not available for such reasons, it's substituted withthe symbol ==.

5.3.1 RF Power switch menu (Fnc)

From this screen the user can switch on and off the power amplifier.

When the amplifier is set in the OFF state, the inner conductor of the INTERLOCKconnector will be grounded to force the exciter in stand-by mode(if it is fitted withsuch an option, as RVR exciters are, and if the devices are correctly linked). At thesame time, the auxiliary AC power output circuit is opened to shut off the exciter if itis connected to this plug.

A few seconds after the amplifier is set in OFF mode, the software sends a signalto the relaysof the blowers to turn them off too (the delay allows for the propercooling of the amplifier).

5.3.2 Power menu (Pwr)In this multi-line scrollable screen it is possible to read all the measurementsrelated to the behaviour of the power section of the amplifier: Forward Power (Fwd Pwr) Reflected Power (Rfl Pwr) Standing Wave Ratio (SWR) Input Power (Inp Pwr) Internal SWR (Int SWR)

Depending on the configuration, some of the measurements can be disabled.

The complete aspect of the screen is the following (please note that only two lines at

5.3.3 Power Amplifier menu (P.A.)In this multi-line scrollable screen it is possible to read the values of the parametersrelated to the RF amplifier section of the device: voltage (VPA) current (IPA) efficiency temperature mains voltage (Percentage variation referred to nominal voltage)

The complete aspect of the screen is the following (only two lines at a time arevisible, use the UP and DOWN buttons to scroll):

5.3.4 Threshold setting menu

As it has been said in the introduction, the amplifier offers a maximum of three usersettable alarms. For each of them, one of the working parameters is compared againsta threshold value that can be be modified by the user. The results of the comparisonsare available on the telemetry connector or as dry contacts on the optional externaltelemetry board, and can be read on the display as "O" (open, i.e. the result is false)or "C" (closed, i.e. the result is true).

Two seatteble thresholds (Power Good) regard the emitted power level, the third isused to verify the quantity of reflected power (Reflected Warning).

PJ500M-C

15 / 28User Manual Rev. 1.5L - 14/10/02

The thresholds are shown as percentage of full-scale value.

The full-scale value for PJ500M-C are: Forward Power 500W Reflect Power 50W

It is also possible to change those values executing the following procedure: Select the line to modify (UP and DOWN buttons) Push the ENTER button Modify the value of the threshold (UP and DOWN buttons) Push the ENTER button to confirm

The following figure shows an example of configuration for this menu

In this example, the thresholds of the warnings are: PwrGd1 400W (80% X 500W) PwrGd2 250W (50% X 500W) RflWar 20W (40% X 50W)

5.3.5 Alarms menu

This screen gives to the user information regarding the status of the protectionsystem included in the amplifier.

It consists in a number of lines, each of wich holds the name of the quantity that ischecked by the protection system and the kind of intervention that is undertaken.

The latter can be: of the kind X - (Y), Wait, or Disabled.

The aspect of this multi-line screen is the following (only two lines at a time arevisible, use the UP and DOWN buttons to scroll):

5.3.6 Various menu

This menu permits to effect two operation: Setup the address of the I2C serial bus type connection. Setup the kind of visualitation in the default menu.

The default address of I2C communication is foundamental when the amplifier isconnected whith other RVR devices that use this protocol. Its raccomended not tochange this parameter if not necessary.

The visualitation mode can be digital (the default mode described in chapter 5.3) oranalogic:

In analogic mode, a little triangole indicates the reflected power level setting inthreshold setting menu (RflWar) and the bar below shows the reflected power in realtime.

PJ500M-C

17 / 28User Manual Rev. 1.5L - 14/10/02

This kind of visualitation is best used when the amplifier output is connected to adevice that needs tuning.

5.3.7 Version menu

This screen shows the different version of hardware (H.V.) and software (S.V.) of theunit.

5.3.8 Protection system

The protection system implemented by the software is based on two kinds of reaction.

The first reaction is called "Foldback", and consists in lowering the RF power stagevoltage in case the forward or reflected power surpass a certain value. In this way,the gain of the amplifier gets smaller, and the overall effect is an opposition to theincrease of both the forward and the reflected power. A yellow LED on the front panelsignals the intervention of the foldback circuit.

The second kind of reaction consists in shutting off the power stages of the amplifierwhen a certain quantity exceeds the configured value.

Depending on the kind of problem that caused the failure, after the amplifier hasbeen shut off, it will either be reactivated after a fixed time interval, or only when theimpeding condition has been solved. In the Alarm menu, the first kind of configurationis noted by X - (Y), wile the second is indicated with Wait. The third possibility is thatthe configuration of the sistem does not implement any protection based on a certainparameter: This would be noted with Dis. (Disabled).

While the amplifier is temporarily shut off for an alarm, the yellow WAIT LED is lit, andthe cause of the intervention of the protection system is written on the display.

When the protection intervenes for a parameter of "cyclic" kind, a counter isincremented (the value X in the alarm screen). If the value of the counter reaches themaximum admitted value (Y), the amplifier is definitively switched off, and the redLED "fault" on the front panel is lit.

The button ALARMS RESET gives the user the opportunity to interact with theprotection system. Its effect is different depending on the status the amplifier is whenthe button is pushed: If the system is off, waiting for the cycle time to be reached, or if it is definitively off

in FAULT state, pushing the ALARMS RESET button will immediately turn the

PJ500M-C

18 / 28 User ManualRev. 1.5L - 14/10/02

amplifier on and reset the alarm counters If the system is transmitting, but some alarm occurred before, so that the alarm

counters are not all at "0", pushing the ALARMS RESET button will have noeffect unless the button is pushed wile the user is reading the Alarm menu. In thisway it is assured that the user doesnt reset the possible alarms without beingconscious of them

The alarm counters are reset by the system itself without the need for an externalintervention after half an hour of undisturbed (i.e. without alarms) working of theamplifier

8.2 Power supply

The power supply are housed in the left side of the amplifier. The Switching PowerSupply is mounted on a heats that allows its cooling through forced ventilation.

Housed inside to the PJ500M-C the are two transformers, both having a selectableinput for voltages of 110 and 220 Volt.

The first has one output, 61-0-61 Volt for Switching Power Supply.

The second has three outputs: 18-0-18 V, 0-15 Volt, C 0-15V, the output A drivethe Alarms Card and the Soft Card, the outputs B and C supply the Control Sectionof Switching Power Supply.

Inside the Alarms Card a rectifying and stabilization circuit provides the +15 and -15V needed by the electronics.

8.3 Soft Start

The soft-start card is a board placed on the left side of the amplifier.

This circuit imposes a resistive load when the amplifier is activated and excludes itafter a certain delay. In this way, the current spikes due to the transformer at power-on are reduced.

8.4 Input directional coupler

The function of this circuit is to provide the measurement of the input power, thatelaborated by the software for the protection of the amplifier. This card also hoststhe temperature sensor, that is monitored by the software too.

8.5 RF Power Amplifier

The R.F. Power amplifier section is composed of the two power modules coupledwith a Wilkinson Splitter and Combiner realized with "Strip Line Technology".

The four R.F. modules, splitter card and cobiner card are housed in the top side ofthe equipment.

All R.F. section is mounted on a heat-sink that allows its cooling through forcedventilation.

Each module delivers 300W with 4-6W of drive and is supplied by an switchingpower supply.

The quiescent parameters of each module are:

PJ500M-C

26 / 28 User ManualRev. 1.5L - 14/10/02

VDC=50V Vgs=3.5V Idq=200mA

The active device employed is a Mosfet (BLF278).

8.6 Wilkinson Splitter and Combiner

Both the splitter and the combiner are realized in Strip-Line technology".

The Splitter Card is used to split the RF power of the exciter and provide half of itto each R.F. Power Amplifier moudule.

The Combiner Card is in turn used to combine the output power of the R.F. PowerAmplifier moudules to obtain the total rated power.

These two circuits garantee equal phases of the power of each R.F. Power Amplifiermodule. A power resistor placed on each circuit is used to dissipate any powerdue to unabalancement of the power paths in case of fault of one of the modules.

8.7 Bias Card

This card has the function to control and if necessary to correct the polarization currentof each Mosfet of the R.F. section.

It is also able to supply measurements as: currents, voltages for each R.F. amplifiermodule, total current and average voltage.

8.8 Low-pass Filter

This filter is housed in the right side of the equipment. Its role is to suppress theharmonic components generated by the amplifier under the levels required byregulations.

8.9 Ouput Directional Coupler

The function of this circuit is to provide the measurement of the forward andreflected output power.

8.10 CPU

This subsystem is composed by three cards: the CPU card, the display card and theanalog section card.

This subsystem implements all the software functions (measurements, protection,control, data display, communications) described in the previous chapters.

8.12 External telemetry card (optional)This optional device is designed to interface to the telemetry connector of thePJ500M-C/LCD, and its main role is to give to the user a number of dry contactsrelated to the status of the amplifier. The contacts can be configured as normallyopen or closed, and are triggered by the four user settable thresholds plus LOC/REM, WAIT, FAULT, ON, OFF, INHIBIT.

The analog signals produced by the amplifier are replicated on a DB9 connector.

8.13 PFC Switching Power Supply (optional)This optional module, replaces the assembly composed by the main transformer,the soft start board and the standard switching power supply. The data sheet ofthe module is included in the appendix of this manual.

Among the pros of this option are the active power factor correction (0.99), abetter efficiency, and a reduction in weight of the machine.

The modified wiring diagram of the amplifier using this type of power supply isincluded in the technical appendix.
