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.

5. 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.

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.

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. The socket must be connected to the multipole
cable that will be wired to the mains switchboard.
ATTENZIONE: to avoid any risk of shock make absolutely sure that the power
supply cable is NOT powered when the multipole socket is connected to the
cable itself.
Connect the multipole socket to the power supply cable as described below and

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

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

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�.
