Additional important features of the

PJ10KPS-CA

are as follows:

● The 2.2 kW amplifying modules are implemented by means of plug-in technology: the individual modules may be removed for performing maintenance operations, for instance, without having to turn off the transmitter. The transmitter keeps working at reduced power even if the module has been removed. This operation may be carried out without any risk of damaging the module itself, or the amplifier as a whole, thanks to the control system and to the RF connectors, the power supply and the purposely designed data-exchange.

● Each module is controlled by a microprocessor-based card that checks and adjusts its operating mode. The resulting data are transmitted to the control unit.

For further information refer to the maintenance section.

The control unit manages the changeover of the two exciters both in automatic and manual mode.

The amplifier can work as usual even if the control unit is not present. In fact, the control unit may be substituted temporarily with an electromechanical interface by means of which the user may give the ON and OFF commands to the machine. However, in this case all the numeric type information will be missing and the power level remains the last one enabled before removing the control unit.

● Immediate power foldback under severe / damaging fault conditions of VSWR. The power of transmitter should automatically come down to a suitable safe design limit, so that the transmitter and its subsystem does not get damaged due to load mis match. Details of fold back to be provided.

The foldback function, on the VSWR protection, works automatically on bias voltage and PA voltage, reducing them to ensure that the machine can work at maximum power, not to damage internal organs (mosfet, combiners and dummy load).

4.3 Options

The

PJ10KPS-CA

● Dual exciter

envisages the following options:

● N+1 configuration

● Different kinds of exciters

● Automatic restore after safety tripping or manual restore

● Isolation transformer with surge arresters

● Electromechanical telemetry

4.4 Operating principles

This description is based on the block diagram shown in Figure 4-1.

The

PJ10KPS-CA

amplifier essentially comprises two blocks:

● The Splitter-Coupler section

● The RF amplifier section

The Splitter-Coupler section performs all the treatment of the RF signal except for the power amplification.

Figure 4-1 Block diagram of PJ10KPS-CA

The RF signals generated by two exciters (in the redundant configuration) are first attenuated by 6 dB to improve the uncoupling among the stages and then connected to a coaxial relay commanded by the control unit. One of the two signals is closed on a dummy load built into the machine whereas the other signal is connected to the input splitter. The power of both signals is measured by specific directional couplers.

The RF signal of the selected exciter is divided into five branches, each of which is passed to the input of an amplifying module.

The five RF amplifiers branches are recombined by the coupler at the output of the amplifying modules. The overall amplified RF signal is filtered by a low-pass filter for eliminating the harmonics and is therefore available at the output connector.

The Splitter-Coupler section is controlled by a microprocessor-based card, which makes the values detected at the various measuring points available for the user and for the diagnostics functions.

The system contains five RF sub-amplifier modules each of which is capable of supplying a maximum of 2.2 kW RF. Each RF sub-amplifier module incorporate a PFC (Power Factor Corrector) power supply that provides the utmost power efficiency for enhanced energy savings and environmental protection.

Each RF sub-amplifier module contains a first stage with gain that varies (driver) according to the

MOSFET BLF175. The RF signal amplified by the driver is then separated into three branches, amplified by three LDMOS MRF6VP11KHR5, recombined and filtered by a low-pass filter (Figure 4-2).

Each RF sub-amplifier module is controlled by a microprocessor-based card, connected to the other microprocessor-based cards of the system by means of a RS485 type bus.

Each RF sub-amplifier module runs the Automatic Power Control function for regulating the supplied power: the gain of the amplifying stages and the voltage supplied by the switching power supply unit are regulated so that the power that is output from the RF sub-amplifier module corresponds, if possible, to the set level.

The overall power that the

PJ10KPS-CA

must supply is controlled by the microprocessorbased card of the splitter-combiner section according to the settings made on the control unit for the NOMINAL

POWER and LOWER POWER parameters.

5.2 Buttons, selector switches and LEDs

The typical machine-control operations are performed using the buttons of the control unit’s panel. Specific LEDs correspond to each button and selector switch for indicating the machine’s status.(Figure 5-16).

Figure 5-16

The functions performed by the controls are as follows:

Funzione Descrizione

OFF Button for turning off the machine. A LED signals that the machine is OFF. In this status, the exciters and the pumps,are off.

STDBY Button for setting the machine in standby. In this status the transmitter does not emit any power, but is ready to start the transmission: the main blower is on, the RF modules are not powered, the exciters are on but locked by means of an interlock. The stand-by is used to test the exciters, in fact in manual modality the operator could arrange them in base to the own requirements; coming from an “On” in manual modality, the system does not touch the interlock. Stand-by status is signalled from a LED.

In manual and in stand-by the inhibit of the device doesn’t intervene on the interlock of the exciters. This could necessary when the apparatus is in configuration n+1 for verify if the exciters are operational.

ON Button for turning on the transmitter. The RF power supply is activated.

If the command is set to MANUAL CHANGEOVER EXCITER

(led on), exciters will block interlock and have to go through in

“exciters menu” of CU to enable them manually.The exciters should deliver a power of at least 15 W to start the transmitter.

Use this button to set the changeover system in manual or automatic mode. The signaling LED turns on when the manual mode is selected. On performing a changeover, the exciter connected to the amplifier is deviated toward the internal dummy load and vice-versa. The operator must use the exciters menu to perform the changeover in manual mode.

This LED indicates an attention condition (something is not working properly, but the amplifier is still running)

This LED indicates a fault (the amplifier is blocked, and required the intervention of an operator for the restoration)

This LED indicates the status of waiting (the amplifier is temporarily disabled, but will be reactivated automatically when the blockage is removed, or after a set period of time depending on the type of protection)

This LED indicates an external inhibition. This check is run on the parallel interface (JP4/4)

5.3 Alarms

The menu Alarms of the control unit reports all the events connected to possible malfunctioning of the equipment or due to external causes.

Each registration contains the reference to the concerned module, the kind of event and its date and hour.

The module that detected the event is indicated by one of the following acronyms:

• C.U. (Control Unit)

• P.S. (Power supply)

• R.F. X (RF module number X - from 1 to 5)

• Combi (Combiner/Splitter)

The type of event allows to identify the origin and the consequence of the fault. The first letter of the type of event can be one of the following:

W “Wait” event that causes the temporary block of the piece of equipment that will

be removed as soon as the problem is solved.

R “Retry”, event that causes a temporary block of the piece of equipment, that will

effect a restart attempt after a fixed lapse of time. (Max. 8 attempts)

F “Fault”, event that causes the block of the equipment and requires the intervetion

of an operator for the restart.

E “Error”, event that doesn’t cause the interruption of the supply of power, but can

reduce the functions of the equipment (e.g cannot be done the changeover fun-

ction of the exciters)

The possible event types are listed in the table below.

8 Installation and use

This chapter contains the basic instructions for installing and using the PJ10KPS-CA amplifier. If necessary, more in-depth information about the operating principles may be traced in the next chapters.

8.1 Assembly

For practical reasons and for transport safety, the machine is usually supplied disas-sembled to the customer. The assembly procedure is rather simple and can be car-ried out by any qualified technician.

Caution: In order to avoid the risk of damaging the machine and/or of injuring the operators, it is advisable to closely adhere to the instructions provided below. always respect all the safety regulations and standards in force.

Identify the machine components:

• The rack (various components are assembled, such as the coupler, the splitter, the control unit, the main blower) [Figure 5-1 a)]

• The 5 RF modules [Figure 5-1 b)]

• The exciters [Figure 5-1 d)]. (As a rule the amplifier is supplied as a complete transmitter. This example shows two PTXLCD exciters produced by R.V.R.

Elettronica. Usually the exciters are pre-assembled inside the rack).

Check that all the components are in perfect working order. Should there be any kind of problem, for instance if there is any damage caused by the transport of the components, read the instructions associated with the Warranty at the beginning of this manual (chapter 2).

1. Install the rack in the location where the transmitter will work. The rack is mounted on wheels for simplifying its movement, therefore after having positioned it where expected, it is advisable to use the four screws at the bottom of the rack to steady it perpendicular to the ground.

The transmitter is cooled by forced ventilation. The air outlet is on the machine’s roof whereas in the standard configuration the air intake is envisaged at the back of the machine. If you opt for this solution, install the machine at least 50 cm. away from the back wall, so that air can flow under optimal conditions.

2. Remove the protection panels of the RF modules .

5-2].

Figure 5.2

The modules have a groove at the top and one at the bottom: insert the modules so that the guides in the compartment fit into these grooves. Slide the module until the two fixing screws fit into their seats. Then tighten the fixing screws at the same time so that the module inserts into its compartment remaining parallel until it is perfectly in place.

4. Connect the machine’s main power supply cable. Route the cable (5-pole type) through the raceway on the machine’s roof [Figure 5-5 a)] and fix the conductors to the terminals of the top [Figure 5-5 b)].

PJ10KPS-CA

!

Caution: The connection of the machine to the electric alimentation is performed fixing to a 5 poles cable with bare terminals to a terminal block. Making sure without any possibility of error that the cable is not under tension while working on it.

It is reccomended not to turn on the machine without first have connected the RF exit to the antenna or to the dummy load!

The PJ10KPS-CA requires a three power supply 3F (black, brown and grey) + N

(blue) + GND (green yellow) able to give 50A for phase. Keep this requirement in mind in connecting to the personal distribution board.

5. Reposition the protection panels of the RF modules.

6. If the PJ10KPS-CA was not supplied complete with pre-assembled exciters, insert and connect the exciters into the appropriate housings.

8.2 First start

This section describes the procedure for powering-on the machine the first time.

For simplicity’s sake, the automatic control capacities of the exciters are temporarily disabled.

8.3 Preliminary operation

Before activating this piece of equipment, the necessary connections must be performed, and in particular:

• Power supply (MUST BE EQUAL TO WHICH HAS BEEN DESIGNED THE

MACHINE, OTHERWISE YOU MIGHT PERMANENTLY DAMAGE,

R.V.R.

ELETTRONICA S.p.A. DOESN’T ASSUME RESPONSIBILITY.)

• Modulating signals

• RF load (antenna feeder or dummy load).

The machine’s RF output is the “EIA 1 5/8” flanged type and is accessed on the roof of the PJ10KPS-CA. If a dummy load capable of dissipating the RF power generated by the transmitter is available, it is advisable to run the first tests by connecting to it rather than to the transmission antenna.

8.4 Power-on

When powering-on the transmitter the first time, perform the operations outlined in the table below.

The “Result” column indicates the immediate results of the operations performed plus a few indications that confirm that the machine is working efficiently.

Should any inconsistencies occur as compared to these indications, interrupt the procedure and identify the reason for the malfunction before resuming the procedure.

Operation Result

Turn the “Mains” switch The whole transmitter is powered. The machine is activated in the same status it was in when it was turned off the last time

Press the OFF key of the control unit

RF emission by the transmitter is inhibited; the exciters are off; the RF amplifier modules are off

Press the EXCITER CHANGEOVER key of the control unit

The automatic management for the exciters changeover is disabled.

The MANUAL LED must be on (otherwise press the key again)

Press the STDBY key of the control unit

The exciters are turned on in interlock status. The RF amplifying modules stay disabled. Being in manual modality, the exciters could be unlocked to verify the operation (see 8.5).

Set the parameters of the control unit

This procedure is described in chapter 5 on in this manual. The control unit communicates the nominal power and reduced power values to the

Set the exciters

RF modules. It also handles the coaxial relays so that the on air exciter is the desired one and sets the exciter to ON mode

Adhere to the instructions of the exciters used for setting the required work frequency on the exciters. Regulate the output power of the exciters to 20 W.

Press POWER LOWER and ON

The current exciter is activated (the interlock is released from the exciter) and its power emission is enabled. The power emitted by the

PJ10KPS-CA amplifier increases gradually until it attains the level that had been set previously as “Reduced power”. Check the emitted power level by means of the analog instrument with the selector switched to

FWD PWR position

Press NOMINAL POWER

Power supplied by PJ10KPS-CA increases and attains the set nominal value. Check it on the analog instrument.

When the transmitter is on and works at its nominal power, the whole series of

“accessory” checks and settings deemed necessary may be carried out before starting up the apparatus.

8.5 Control unit settings

The settings of the control unit that are required for starting up the machine, mentioned in the powering-on procedure, are the following:

1. Setting of the power levels

2. Setting of the on air exciter

Before performing the first operation, click the ESC and OK button. The display shows the screenful for selecting the menus [Figure 5-7]. Click the arrow keys until the cursor highlights the line associated with the Setting menu. Click OK: the software will show the associated screenful on the display [Figure 5-8].

On having accessed the Settings menu, use the arrow keys to select the nominal power line (Pwr. Out) and click OK. Use the arrow keys to decrease or increase the indicated percentage value up to the required level. Click OK again to set this value.

Repeat the operation for the line associated with the reduced power level (Pwr. Lower).

The new power level is transmitted to the combiner module and then stored in EEPROM only when the ESC button is clicked.

When inside this menu, it is advisable to check the date and time lines and update them if necessary. Note: the date and time are used only for marking the events in the alarms register.

The date and time do not need to be updated in the transmitter in order for it to work efficiently.

On having completed these settings, click ESC to return to the selection screenful.

In order to set the on air exciter, select the Exciters menu [Figure 5-9]. Take into consideration the On Air Exciter line: the number to the right indicates the exciter being used. To change it simply highlight the line and click OK.

To have the correct efficiency of the transmitter, the exciters should stay at 20/22 W, unless stated otherwise indicated on the modulator, depending on the version and frequency. The power of the transmitter should be adjusted from the menu “Settings”.

DO NOT RESPECT THIS COULD DAMAGE THE EQUIPMENT

LDMOS, RVR ELETTRONICA S.P.A. DISCLAIMS THE WARRANTY.

The exchange of the exciters is assisted from the software, that is when the commutation is carried out , the interlock comes systematized in the correct way independently from like they were. The interlock could be modified also manually in case of necessity.

Management of the exciters

The control unit can perform the automatic changeover between exciters if one malfunctions. The Manual LED on the panel indicates, when it is lighted up, that the automatic changeover function is disabled. In order to enable it, click the EXCITER

CHANGEOVER button and check that the LED turns off.

In function of the state of the PJ10KPS-CA automatism, the behavior of the machine will be various. In this chapter are described the different cases.

8.6.1

Start-up from power-on with exciters in manual mode

When powering on the machine with the exciters in manual mode, the apparatus does not perform any check, both mute RF signals are active and the changeover relay remains in standby status. Use the exciters menu to activate an exciter.

NB

This is why, if the transmitter is left in manual mode, any momentary power failure will cause the transmitter to be inactive when turned on again. Therefore it is advisable to leave the PJ10KPS-CA in automatic mode when you are not performing maintenance operations.

8.6.2

From OFF to ON with exciters in manual

When switching from OFF (or STDBY) to ON with the exciters in manual mode, the apparatus does not perform any check and the exciter that is currently set to on air is the one that is aired.

If the mains signal is not OK, the exciters turn off automatically.

If the maximum drive power is exceeded during operations, the PJ10KPS-CA is set to fault status and power supply is cut to the exciters. A message in the alarms menu signals this fault.

When the apparatus is set to STDBY, the mute RF signals of the exciters are not activated and may be modified by the operator.

When the apparatus is set to EXT INT or AUX INT, the mute RF signals of the exciters are not activated and may be modified by the operator.

User & Technical Manual

231

PJ10KPS-CA

8.6.3

Automatic changeover

When the PJ10KPS-CA is in the exciter automatic changeover mode, the power emitted by the on air exciter is checked constantly. If at any time the on air exciter is no longer good (i.e. power drops to below the preset level), the apparatus is kept operational whereas the exciter connected to the internal Dummy Load turns on.

If the latter one is good (i.e. it is capable of supplying the required power), then the two exciters are changed over. Instead if the alternative exciter is not good, no changeover takes place, the control unit commands the mute RF of the exciter to

Dummy Load, it waits 120 s. and repeats the attempt. This procedure is repeated indefinitely until one of the two exciters is considered to be good.

During the whole length of time during which there is no good exciter, the PJ10KPS-

CA keeps the WAIT LED on for signaling this status.

Each exciter is fitted with its own mute RF. On being commanded, the piloting signal must return to zero within 3 seconds at the most. If this does not occur, the fault is recorded by an error message that is entered in the alarms menu.

If the mains signal is not OK, the exciters turn off automatically. If the piloting power exceeds the limit during operations, the PJ10KPS-CA is set to the FAULT status and the power supply of the exciters is turned off. A message in the alarms menu signals the fault. Keep in mind that the operator’s intervention is required to exit from the FAULT status.

If the MAINS signal coming from the bus is not OK, the exciters are all turned off.

As soon as the MAINS signal is regular again, the evaluation cycle of the exciters begins (see 8.6.4).

When the apparatus is set to STDBY, the mute RF signals of the exciters are activated and as such both exciters are inhibited. If the ON key is pressed, the system re-evaluates both exciters in the same manner as in the procedure from

OFF to ON (see 8.6.4).

When the apparatus is set to EXT INT or AUX INT, the mute RF signals of the exciters are activated and therefore both exciters are inhibited. When the external interlocks are released, the system re-evaluates both exciters as during the phase from OFF to ON (see 8.6.4).

8.6.4

Phase from ON to OFF

When the apparatus is set to OFF status and you press the ON button, the power supply of the exciters is activated and the logic starts to evaluate the exciters. During the evaluation phase, the WAIT LED stays ON.

When the apparatus is turned OFF, it memorizes the exciter on air. Consequently when the machine restarts it can attempt to restore the previous conditions. On the machine restarting, if the exciter that is to be aired does not attain the preset power level whereas the spare one is operational, the apparatus performs the changeover when the evaluation time (120 s.) expires.

User & Technical Manual

232

PJ10KPS-CA

On the machine restarting, if both exciters do not attain the preset power level, the apparatus airs the one that had been present when the machine was turned off, after the evaluation time has expired.

8.6.5

Start-up with exciters in automatic mode

The sequence run by the PJ10KPS-CA, when the power supply is activated while it is already in ON status and the exciters are in automatic mode, is identical to the one run for switching from OFF to ON. The only difference is that a screenful displays the countdown for determining the fault of the exciters. During this phase the manual/automatic button is inhibited and in order to set the exciters to manual mode you must press the OFF button of the apparatus.

8.6.6

Audio alarm

The control unit of the PJ10KPSCA can manage a fault signal, for each exciter, which normally has an “Audio Alarm” meaning. The control software of the PJ10KPS-

CA does not intervene in triggering these signals since they must be checked by the exciters (or by any other connected devices).

The Audio Alarm signals are made up of two inputs for the logical signals on the parallel interface and on the “mute RF” command connector of the exciters.

The control unit manages these signals just like it manages the power good signals:

• Each “Audio alarm” signal is associated with its own exciter

• If the audio signal, associated with the exciter that is currently on air, enters an alarm status, the PJ10KPS-CA waits for the time configured in the exciter menu before it attempts the restoring operation

• If the audio of the aired exciter is still in alarm status on the elapsing of the aforesaid time interval, the control unit checks if the audio of the exciter on the dummy load is regular. In this case the changeover between the exciters is performed.

Observe the following differences as compared to the case in which power is missing:

• The management of the “Audio alarm” signals is not active during the start-up phase and during the switching phase from OFF to ON, but only when the exciters are working in automatic.

• In the standard configuration, the aforesaid sequence continues until the audio signal associated with one of the exciters becomes regular again. In the “N+1” configuration, the switching attempt is performed only twice, after which the

PJ10KPS-CA enters the fault status.

• An Audio Alarm output is provided on the parallel interface: this signal is activated

(with no delays) when the audio of the exciter that is currently on air is in alarm status.

8.6.7

Protection and alarms

The PJ10KPS-CA contains a complete protection and alarms system, both at the individ-ual modules level and at the control unit level.

The modules are fitted with a micro-processor-based system that manages any malfunctions locally. The associated information is communicated to the control unit for displaying and storing the events and for the centralized management of the events that require it.

Certain LEDs of the PJ10KPS-CA panel are dedicated to the management of the alarms:

LED Description

WARNING This LED indicates a warning (something is not correctly working, but the amplifier is still working)

FAULT

WAIT

This LED indicates a fault (the amplifier is shut off, the operator’s intervention is required)

This LED indicates the wait status (the amplifier is temporarily off, it will be restarted as soon as the reason that keeps it from working will be removed, or after a fixed amount of time depending on the reason of the intervention of the protection system)

The ALARM RESET button is used for resetting the alarms and restarting the machine.

A complete description of the alarms and protection system is given in chapter 5.3.
