4.1 General Description
PJ500C-LCD, PJ700C-LCD ePJ1000light are compact radio broadcasting
amplier manufactured by R.V.R. Elettronica SpA featuring adjustable RF power
output up to 500, 700 and 1000 W, respectively, under 50 Ohm standard load and
less than 20W drive power requirement.
PJ500C-LCD, PJ700C-LCD and PJ1000light have been designed for installation
in a 19”x3HE box for rack.
These ampliers incorporates a low-pass lter to keep harmonics below the limits
provided for by international standards (CCIR, FCC or ETSI).
Two major features of PJ500C-LCD, PJ700C-LCD and PJ1000light 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.
The RF power section of PJ500C-LCD uses two MOSFET modules delivering up
to 300W output power each, PJ700C-LCD uses two MOSFET modules delivering
up to 350W output power each, whereas PJ1000light features three MOSFET
modules with up to 350 W output power each.
An LCD on the front panel and a push-button panel provide for user interfacing with
the microprocessor control system, which implements the following features:
• Output power setup
• Power output enable/disable
• User-selectable threshold settings for output power alarm (Power Good
feature)
• Measurement and display of amplier operating parameters
• Communication with external devices, as programming systems or telemetry
systems through RS232 or I2C serial interface

4 / 32 User ManualRev. 1.0 - 20/06/08

5. Quick guide for installation and use
This section provides a step-by-step description of the machine installation and
conguration procedure. Follow these procedures closely upon rst power-on
and each time any change is made to general conguration, such as when a new
transmission station is added or the exciter is replaced.
Once the desired conguration has been set up, no more settings are required
for normal operation; at each power-up (even after an accidental shutdown),
the amplifier 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 rmware features and
capabilities. Please see the relevant sections for additional details.
IMPORTANT: When conguring and testing the transmitter in which the amplier
is integrated, be sure to have the Final Test Table supplied with the machine 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 amplier 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 230 VAC or 115 VAC (-15% / +10%) mains power supply with
adequate ground connection
√ FM exciter with adjustable output power up to 20W (as a minimum), like RVR
Elettronica PTX30-LCD
√ For operating tests only: dummy load with 50 Ohm impedance and adequate
capacity (500w for PJ500C-LCD, 700w for PJ700C-LCD or 1000 W for
PJ1000light as a minimum)
√ Connection cable kit including:
• Mains power cable

PJ500C-LCD, PJ700C-LCD & PJ1000light
5.1.2 Mains power supply
WARNING: Disconnect mains power supply before beginning these
procedures.
Both power supply units (please see chapter 8.1 for a detailed description) are
equipped with fuses and voltage selection blocks: check all fuses and voltage
selection blocks to ensure they are properly rated for the power mains and
change them as required to match mains voltage.
All mains power supply protection fuses are conveniently located on the rear panel
and are easily accessed (see gure 6.2): to check or replace a fuse, disconnect
machine from power mains, unscrew fuse cover and pull fuse out of socket.
The following fuses are used:
PJ500C-LCD /
PJ700C-LCD
@ 230 Vac/115 Vac
PJ1000light
@ 230 Vac/115 Vac
Main Power Supply
(g. 6.2 – item [7] e [20]) (2x) 25A type 10x38 (2x) 25A type 10x38
Service power supply
( g. 6.2 – item [19]) (1x) 1A type 5x20 (1x) 2A type 5x20
Table 5.1: Fuses
Ensure that machine is appropriately set for available mains voltage (supply voltage
rating is reported in the Final Test Table) as follows: disconnect machine from
mains and ensure that the voltage selection block of the power supply located on
the rear panel (see g. 6.2) is set to the appropriate voltage; change setting as
required.
The main power supply unit is the full-range type and requires no voltage setup.
When supply voltage is other than 230 Vac and might cause erratic operation (say,
less than 200 Vac), it may help to move jumper JP3 on the PFC controller board
from position 2-3 to 1-2 (see PFCPSL1000 diagram, in gure 9.1 and detail in
gure 5.1 below).

available from R.V.R. Elettronica) to the RF input (see gure 6.2) using a 50-Ohm
coaxial cable with suitable connectors. To begin with, set exciter to minimum output
power and switch if off.
Connect the amplier INTERLOCK OUT output (gure 6.2) to the matching
INTERLOCK IN input tted on all R.V.R. Elettronica exciters as standard; if your
exciter is a different brand, identify an equivalent input.
Connect the RF output (see gure 6.2) to an adequately rated dummy load or to
the antenna.
WARNING: Electric shock hazard. Never handle the RF output connector
when the machine is powered on and no load is connected. Injury or death
may result.
Ensure that the POWER switch on the front panel (see gure 6.1) is set to
“OFF”.
Connect the mains power cable to the MAINS terminal board on the rear panel
(see gure 6.2).
Note : The mains must be equipped with adequate ground connection properly
connected to the machine. This is a pre-requisite for ensuring operator safety and
correct operation.
WARNING: The power supply connector is a terminal board. Ensure the wire
is not live before performing the connection.

NOTE: This feature prevents the machine from delivering maximum power as
soon as output is enabled from menu 4, or in the event the machine is already
set to ON and energised.
2) Ensure that machine is not in a locked-out state. Press the ESC key (chap.
6.1) to call up the selection screen (Menu 3). Highlight Fnc and press ENTER
to conrm (chap. 6.1) and access the appropriate menu (menu 4).
If LOC is set to REMOTE (machine remote control), move cursor to LOC and
press ENTER (chap. 6.1); label will change to LOCAL, i.e. local control operation
mode.
In the same menu, ensure that power limiting is disabled: if PWR is set to OFF,
i.e. power output is disabled, move cursor to PWR. Press ENTER (chap. 6.1)
and label will switch to ON, i.e. power output enabled.
Press ESC (chap. 6.1) twice to go back to the default menu (menu 1).
3) Fine tune power setting from menu 2 (see description of item 1b) until achieving
the desired value.
WARNING:Equipment is capable of delivering more than rated output power
(500W for PJ500C-LCD, 700W for PJ700C-LCD or 1000 W for PJ1000-LIGHT);
however, never exceed the specied power rating.
NOTE: Exciter drive power setting should never exceed 20W, or it will trigger an
Overdrive Alarm.
NOTE: If power is set to 0 W in the edit mode, the INTERLOCK OUT contact
(chap. 6.2) trips and external exciter power is immediately inhibited.
Next, you can review all operating parameters of the machine through the
management rmware.
Normally, the machine can run unattended. Any alarm condition is handled
automatically by the safety system or is signalled by the LED indicators on the
panel or by display messages.
NOTE: Standard factory settings are: output power set to upper limit (unless
otherwise specied by customer) and OFF.

5.4.1 Operation Menu (Fnc)
In this menu, you can set power output On/Off, toggle between “Local” or “Remote”
control mode and set the Forward Power Good (PgD) threshold rate.
To edit an item, highlight the appropriate line using the UP and DOWN buttons and
then press and hold the ENTER button (chap. 6.1) until the command is accepted.
This way, Pwr setting is toggled between On and Off and Mod setting is toggled
between “x1” and “x10”. To edit the Power Good rate, simply select item “PgD”
and edit its value using buttons and ; nally, press ENTER to conrm (chap.
6.1).
Menu 4
Pwr Enables (ON) or disables (OFF) amplier power output.
Loc Modies machine operation. In the LOCAL mode, the machine can read
and modify its operating parameters through the navigation keys and the
management rmware, whereas all other sources are locked out. In the
REMOTE mode, the machine can only read its operating parameters;
parameters are modied based on the commands received from other
connected telemetry systems.

PJ500C-LCD, PJ700C-LCD & PJ1000light
PgD Modies Power Good threshold for forward power. The Power Good
rate is a percent of equipment rated power (500W for PJ500C-LCD,
700W for PJ700C-LCD and 1000 W for PJ1000-LIGHT), not of forward
output power. This means that this threshold set at 50% will give 250,
350 and 500 W, respectively, regardless of set power level. The Power
Good feature enables output power control and reporting. When output
power drops below set Power Good threshold, the equipment changes
the state of pin [7] of the DB15 “Remote” connector located on the rear
panel (gure 6.2).

5.4.4 Alarm Menu (Alm)
This menu shows any alarm conditions occurring during machine operation. Alarm
thresholds are preset at the factory.
Menu 7
FWD Counter of alarm conditions triggered by forward power.
RFL Counter of alarm conditions triggered by reected power.
INP Counter of alarm conditions triggered by input power.
Reset Alm Alarm counter reset.
Alarm conditions are numbered from 1 to 10 and reect the following situations:
forward output power too high, reected output power too high and input power
too high.
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 (chap. 5.3.4.1). 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 (chap. 6.1).
