Rev. 2.0 - 21/01/17 User Manual PJ5000U-K 4. General Description The PJ5000U-K is an radio broadcasting amplifier manufactured by R.V.R. Elettronica SpA featuring adjustable RF power output up to 5000 W under 50 Ohm standard load and less than 70 W drive power requirement�. The PJ5000U-K is designed to being contained into a 19” rack box of 4HE. 4.1 Unpacking The package contains: 1 PJ5000U-K 1 User Manual 1 Mains power cable The following accessories are also available from Your R.V.R. Dealer: • Options for the machine: /LD-PJ • Spare Parts • Cables 4.2 Features The overall efficiency of PJ5000U-K is better than 70% across the bandwidth, for this reason are part of RVR Green Line family. This performance characteristic is guaranteed in a range between +0.25 dB and -3 dB (+5% and -50%) referred to the nominal power of the equipment: for example from 2500W to 5250W in case of PJ5000U-K; outside these limits the equipment is able to work properly but can not guarantee an efficiency of 70%. The operating logic during the output power regulation, which is necessary in order to not deteriorate the efficiency even of 5-6%, expects to set the pilot power to the optimum power (dependent on the amplifier: for example the PJ5000U-K requires 70 W) and then successively adjust the bar setting of power on amplifier in order to obtain the desired output power. The amplifier incorporates a low-pass filter to keep harmonics below the limits provided for by international standards (CCIR, FCC or ETSI). Two major features of PJ5000U-K are compact design and user-friendliness. Another key feature is its modular-concept design: the different functions are performed by modules with most connections achieved through male and female connectors or through flat cables terminated by connectors. This design facilitates maintenance and module replacement. User Manual Rev. 2.0 - 21/01/17 / 32 PJ5000U-K The RF power section of PJ5000U-K uses eight LD-MOSFET (MRFE6VP61K25H) modules delivering up to 850W output power each.

Quick guide for installation and use This section provides a step-by-step description of equipment installation and configuration procedure. Follow these procedures closely upon first power-on and each time any change is made to general configuration, such as when a new transmission station is added or the equipment is replaced. Once the desired configuration has been set up, no more settings are required for normal operation; at each power-up (even after an accidental shutdown), the equipment defaults to the parameters set during the initial configuration procedure. The topics covered in this section are discussed at greater length in the next sections, with detailed descriptions of all hardware and firmware features and capabilities. Please see the relevant sections for additional details. IMPORTANT: When configuring and testing the transmitter in which the equipment is integrated, be sure to have the Final Test Table supplied with the equipment ready at hand throughout the whole procedure; the Final Test Table lists all operating parameters as set and tested at the factory. 5.1 Preparation 5.1.1 Preliminary checks Unpack the transmitter and immediately inspect it for transport damage. Ensure that all connectors are in perfect condition. Provide for the following (applicable to operating tests and putting into service): √ Single phase mains power supply (P+N) 230 VAC (-15% / +10%) or three phase mains power supply (3P+N) 400 VAC (-15% / +10%) , both with adequate earth connection √ FM exciter with adjustable output power up to 70W (minimum), as the RVR Elettronica PTX100LCD/S √ For operating tests only: dummy load with 50 Ohm impedance and adequate capacity (5000W as a minimum) √ Connection cable kit including�: • Mains power cable IMPORTANT: Specify the kind of power supply when ordering: the machine will be delivered already configured according to your needs. User Manual Rev. 2.0 - 21/01/17 / 32 PJ5000U-K 5.1.2 Predisposition of mains power supply WARNING: Disconnect mains power supply before beginning these procedures. The three power supplies of the equipment (see the following chapters for a more detailed description) have their own fuses and voltage selection: all fuses and voltage selection must be checked and, if necessary, modified on the basis of real power supply that will be used. The mains power supply protection fuses are conveniently located on the rear panel and are easily accessed: to check or replace a fuse, disconnect machine from power mains, unscrew fuse cover and pull fuse out of socket. The following fuse are used: PJ5000U-K Mains fuses 1-2-3 & services power supplies (3x) 25A-T type 10x38 Table 5.1: Fuses Check that the value of mains voltage available corresponds with the value of voltage set on the machine (also reported in the test table), verifying and appropriately modifying, with the equipment disconnected from the mains power, the location of the voltage selection of services power supply is placed on the rear panel. The main power supply, that is of “Full Range” type, not needs to change the settings related to the supply voltage. 5.1.3 Connections Connect the output of a suitable FM exciter (for instance, PTX100LCD/S exciter available from R.V.R. Elettronica) to the RF input using a 50 Ohm coaxial cable with suitable connectors. To begin with, set exciter to minimum output power and switch if off. Connect the amplifier INTERLOCK OUT output to the matching INTERLOCK IN input fitted on all R.V.R. Elettronica exciters as standard; if your exciter is a different brand, identify an equivalent input. 10 / 32 Rev. 2.0 - 21/01/17 User Manual PJ5000U-K Note: the amplifier’s INTERLOCK connector is an output. The operating logic is as follows: the internal conductor fl oats when the amplifi er works correctly, on the contrary power is delivered and the internal conductor is closed to ground to halt the exciter. Connect the RF output to an adequately rated dummy load or to the antenna. WARNING: Electric shock hazard! Never handle the RF output connector when the equipment is powered on and no load is connected. Injury or death may result. An ILME model KKCNTCQF04/2 (CQF04/2) multipole socket is supplied with the amplifier to power the machine.

Pg1 Modifies Power Good (forward power) threshold. The Power Good rate is a percent of machine rated power (5000W for PJ5000U-K), not of forward output power. This means that this threshold set at 50% will give 2500 W regardless of set power level. The Power Good feature User Manual Rev. 2.0 - 21/01/17 15 / 32 PJ5000U-K enables output power control and reporting. When output power drops below set Power Good threshold, the equipment changes the state of pin  of the DB25 “Remote” connector located on the rear panel�. Pg2 Like Pg1 , modifies a second Power Good threshold for forward power. When output power drops below set Power Good threshold, the equipment changes the state of pin  of the DB25 “Remote” connector located on the rear panel�. Pg3 Like Pg1, modifies Power Good threshold for reflected power. When output power drops below set Power Good threshold, the equipment changes the state of pin  of the DB25 “Remote” connector located on the rear panel�. Pg4 Like Pg1 , modifies a second Power Good threshold for reflected power. 5.3.2 Power Menu (Pwr) This screen holds all readings related to machine output power: Menu 5 Note that these are readings, rather than settings, and cannot be edited (note the empty arrow).

Menu 7 FWD RFL INP Counter of alarm conditions triggered by forward power. Counter of alarm conditions triggered by reflected power. Counter of alarm conditions triggered by input power. Reset Alm Alarm counter reset. Alarm conditions are numbered from 1 to 10 and reflect the following situations: forward output power too high, reflected output power too high and input power too high. User Manual Rev. 2.0 - 21/01/17 17 / 32 PJ5000U-K Alarm monitoring cycle is as follows: when an alarm condition is detected, alarm counter increases by 1 unit, machine goes into lock-out state and the display shows the cause for the stop. After 15 seconds, the machine attempts to re-start; if a new alarm condition is detected, cycle is repeated over and over again up to 10 times maximum. If machine re-starts successfully, all alarm counters are reset after 30 minutes’ regular operation. After 10 alarm conditions triggered by the same cause, the machine goes into fault lock-out mode, a lock-out mode warning appears on the display and the “FAULT/LOCK” LED turns on. After the alarm condition has been rectified, the counter can be reset by highlighting “Reset Alm” and holding down the ENTER key for some time. 18.104.22.168 Allarmi and Faults There are three types of alarms that can cause a machine lock-out and trigger a “FAULT/LOCK” indication. When any one of the three alarm thresholds is exceeded, the system will automatically switch to the warning screen (even though the user is browsing system menus) and the following messages are displayed: 1. Over Forward Power Forward power threshold exceeded. Alarm 1 2. Over Reflected Power Reflected power threshold exceeded. Alarm 2 3. Over Input Power Input power threshold exceeded. 18 / 32 Rev. 2.0 - 21/01/17 User Manual PJ5000U-K Alarm 3 Monitoring cycle is as follows: • An alarm condition occurs; • Alarm is displayed and device is locked out for 15 sec.; • Operating conditions are restored; • Verification. Upon reaching the 10 cycle limit, a “FAULT/LOCK” indication is triggered and the device goes into lock-out mode; the appropriate LED turns on (figure 6.1) and this screen is displayed: I. Over Forward Power Forward power alarm display. Stop 1 II. Over Reflected Power Reflected power alarm display. Stop 2 III.Over Input Power Input power alarm display. Stop 3 Once the machine goes into “FAULT” mode, it will no longer attempt to re-start; choose the appropriate reset procedure according to current machine setting: • Machine set to LOCAL control mode - press “Reset Alm” in the alarm menu User Manual Rev. 2.0 - 21/01/17 19 / 32 PJ5000U-K (menu 7) or power off and back on again using the POWER switch. • Machine set to REMOTE control mode - power off and back on again sending the appropriate command via the DB25 connector (pin  and ). There is a fourth alarm that does not trigger a “FAULT” condition, but allows some time until correct operating conditions are restored. When the temperature alarm threshold is exceed (about 85°C), the following screen appears: 4. Over Temperature Temperature power threshold exceeded.

Release date. Shows table loaded in the memory. 5.4����������������� Protection System The protection system implemented inside the amplifier is based on two types of intervention. The first reaction is called “Foldback” and consists in decreasing the voltage in the power amplifier when the forward or reflected power exceeds the proportional limit voltage value. As such, the amplifier’s gain is reduced and the overall result is an action that opposes the increase of the forward or reflected power. The yellow LED on the front panel indicates the tripping of the foldback circuit. The second type of reaction consists in turning OFF the equipment’s amplifying section when a specific variable exceeds a set value. Depending on the type of event that has occurred, after that the amplifier has been turned off, it will be reactivated after a fixed time interval or only after that the sharing which caused the block has been removed. When the protection system trips due to a “cyclic” type parameter, a counter begins counting up (the X value in the alarm menu). If the counter reaches the max admissible cycle value (Y), the amplifier turns OFF definitely and the red “FAULT” LED lights up on the front panel. The user may press the ALARMS RESET key, in alarms menu, to interact with the protection system. If the system is transmitting but alarms were triggered earlier causing certain counters not to be at “0”, will have no effect unless it is pressed while inside the alarm menu. As such, the system will be sure that the user takes note of the alarms that were triggered before resetting them. The system resets the alarm counters automatically after thirty minutes of operation, i.e. the user need not do anything, if the amplifier does not trigger any alarms or after the machine the machine has been turned OFF and then back ON�. 5.4.1 Auxiliary Protection The amplifier contains a second microcontroller that manages local measurements and carries out auxiliary protection functions of the machine together with the main protection system. This microcontroller card indicates its interventions via LEDs��i interventi tramite i LED. User Manual Rev. 2.0 - 21/01/17 21 / 32 PJ5000U-K A delivered power automatic back-off mechanism is envisaged for excess temperature, SWR or current absorbed by a MOSFET module. The yellow FOLDBACK LED indicates this case. A FAULT signal is triggered (red LED) when a fault occurs that stops the power amplifier. This situation is signaled to the machine’s main microcontroller as well and triggers a lock situation (FAULT). The LED FUSE BLOWN indicates that one of the fuses that protects the power supply of the MOSFET modules has blown. In this case the machine keeps running as usual (obviously without the contribution of the module) even if it is advisable to single out and clear the cause for the malfunction and replace the fuse as soon as possible to fully restore the machine’s working efficiency. 5.4.2������������������ Power Supply Units Three power supply units, which work in parallel mode, power the machine. Should one of the power supply units malfunction, the machine automatically compensates the delivered power down to a value compatible with the current deliverable from the surviving power supply. This situation is indicated by the “PS” LEDs on the front panel�. 22 / 32 Rev. 2.0 - 21/01/17 User Manual PJ5000U-K 6.
